Can you check tire pressure on dashboard?
Tire-Pressure Warning – What to Do If the TPMS Light Comes On Getty Images Tire-pressure warning lights are typically located in the gauge cluster of an automobile’s dashboard. Warning lights are usually yellow or amber and resemble a cross section of a tire with an exclamation point and/or the letters “TPMS.” (You can see one in the photo above, just to the left of the speedometer.) This small telltale illuminates to inform you of low air pressure in one or more tires when that issue is detected by the vehicle’s tire-pressure monitoring system (TPMS).
- In general, the light will come on when the air pressure in one or more tires is outside the recommended range.
- Since the tires’ optimal performance and safety benefits are realized within a specific range of air pressure, measured in pounds per square inch (psi), the warning light may illuminate when pressure has dropped as little as 10 percent below the recommendation—long before low pressure is visible to the eye.
Some of the more sophisticated tire-pressure monitoring systems will tell drivers which tire is out of range or display real-time air pressure in each tire—including spare tires, in some cases. If your tire-pressure warning light comes on, don’t ignore it; you could be getting a flat.
- Low pressure could result from a leak or simply from the tendency of a tire to lose about a pound of air pressure every month, as well as a pound for every 10-degree drop in temperature.
- So if your tires are inflated properly in the summer, they could be low enough by the winter months to prompt the tire-pressure warning.
Similarly, if a tire-pressure light illuminates on a cool morning, it could shut off if the ambient temperature climbs high enough to bring the tires back to an acceptable pressure. Tires warm up as you drive, raising their internal pressure by about 3 psi, which is another reason the TPMS warning might be on first thing in the morning and off later in the day. Getty Images Either way, whenever a tire-pressure warning light turns on, it’s time to check your tires with, which costs as little as $5. A monthly pressure check of all your tires can help you keep them at the optimal level of inflation and will enable you to identify slow leaks early—possibly even before the pressure drops low enough for the warning light to come on.

- If your TPMS warning light does come on, find the closest gas or service station and check the pressure of all four tires (plus the spare, if applicable), adding air to any that fall below the range listed on a sticker inside the driver’s door.
Once the tires are properly inflated, the light may go off after you’ve driven a few miles. If the light doesn’t automatically turn off after about 10 miles, the TPMS may need to be reset, as directed in the vehicle’s owner’s manual. If the light comes on and all your tires are within the acceptable range, there’s a chance that you have a No matter what the issue turns out to be, pay attention if the tire-pressure light turns on; you’ll be safer for it, and you might also avoid damaging your tires.

Do Mercedes have tire pressure sensors?
Most modern Mercedes vehicles come equipped with a sophisticated tire pressure monitoring system (TPMS). This system checks the pressure in each of your four tires in real-time and indicates any problems on the dashboard. Driving with properly inflated tires has several advantages:
Safer driving: Under- or over-inflated tires can make handling and braking dangerous. Less tire wear: Properly inflated tires wear less and last longer than when the pressures are incorrect. Better fuel economy: You burn less can when your tires are at the right pressure. Road noise and comfort: You get maximum comfort and reduced road noise when air pressure is optimal.
This is why the Mercedes TPMS system is such a popular feature on their lineup of cars, SUVs and vans. As with all underhood automotive systems, the TPMS can suffer from issues as it gets older. We’ve put together this troubleshooting guide to help you determine when your TPMS is malfunctioning and requires attention.

How do I know which tire is low?
Incorrect pressure can cause poor mileage, uneven tire wear, or a tire blow-out. To prevent these events from happening it is important to maintain proper tire pressure. Check your tire pressure every time you fill your car with gas to ensure that you’re getting the most out of your tires – and that your tires are being treated well.
- 1 Look in the owners’ manual or on the inside of the driver’s side door for the standard cold tire inflation pressure. This number is the lowest PSI one would inflate the tires to and is suggested by the car’s manufacturer. Read below for reasons inflation may be placed higher.
- For most sedans, minivans, and even mini pickups, manufacturers generally recommend a PSI (pounds per square inch) in the range of 27 to 32, but can reach all the way up to 40.
- For larger vehicles that need to carry a larger burden, such as trucks and SUVs, the PSI is generally 4 to 8 PSI greater than it would be in smaller cars, perhaps around 45.
- Also note that the front and back tires may need different pressures, according to the manufacturer.
- 2 Unscrew the valve stem cap from the valve stem on the tire. The valve stem is a black or silver pencil-sized extension near the hubcap, about 1″ (2-3 cm) long.
- 3 Press the air pressure gauge evenly onto the valve stem and record the reading given. If there is a hissing sound, the gauge is not tight or even enough for an accurate reading. The angle of the gauge may need to be adjusted.
- If you are using a digital model gauge, you may or may not need to press a button in order for the gauge to read the air pressure. If you are using a traditional gauge, the metered stick should give you a reading automatically.
- 4 Replace valve stem cap. The cap does not hold air in, but it keeps dirt and moisture away from the valve mechanism in the valve stem, which does hold air in.
- Note that if the reading is the same as the manuals’ specifications, you are done after checking all other tires for the same pressure. If inadequate pressure is in the tires then fill air in the tires. Make sure you put in the correct amount.
- 1 Know that the manufacturer’s PSI recommendations don’t translate into optimum tire performance. For all-around driving, the manufacturer’s specifications are probably ideal, but adding a couple extra pounds of pressure into your tires may mean better fuel efficiency. Overall, adding a few pounds of PSI to your tires may make your ride a bit bumpier and less pleasant, so use with tact!
- An increase in PSI can also result in uneven tire wear, longer required braking distances, and reduced handling. Make sure you don’t over-inflate your tires.
- 2 Understand the myth about the max press value in the owner’s manual or driver’s side door. One popular misconception is that the max pressure suggested by the manufacturer is all the pressure the tire can handle before it pops or malfunctions. In truth, the max pressure is the pressure at which the tires will carry the maximum amount of weight.
- As soon as you inflate the tires past the max pressure limit, be prepared for the possibility of malfunction. If your tires are bearing heavier air pressure, a pothole at high speeds could spell disaster.
- 3 Add a few extra pounds of pressure to the back tires if you’re carrying extra cargo, carpooling, etc. If you happen to be carrying a heavier load in your car, especially if you are traveling for longer distances, don’t be afraid to add a few pounds of PSI to your rear tires to offset the added weight. When the weight is unloaded, release the pressure from the rear tires back to its standard specifications.
- 4 Check the air pressure of your tires as the seasons change. Cold weather will reduce the air pressure, while warm weather will increase the air pressure. It’s therefore very important to check tire pressure when the seasons change.
- 5 Never rely on the eyeball method to gauge air pressure in tires. Don’t get lazy. It’s very difficult to tell the difference between a tire with 10 PSI and 20 PSI. Plus, tires normally exhibit a bit of a bulge on the sidewall of radial tires. If you inflate the tires until the bulge is gone, you run the risk of seriously over-inflating your tires, past the point at which they get a performance boost.

- An under-inflated tire causes more sidewall flexing that increases stopping distance, lowers fuel economy and shortens the life of a tire. In rare cases the tire can blowout because of excessive heat from too much sidewall flexing and can even roll off the wheel in emergency maneuvers. Under-inflated tires will wear down the sidewall by making contact with the rim and the road. As a small thank you, we’d like to offer you a $30 gift card (valid at GoNift.com).

- Tire pressure gauge of good quality. Do not rely on ‘pencil’ type tire gauges. Professional quality tools always pay for themselves over time; buy a professional quality tire gauge.
- Air compressor or pump with correct fitting (bicycles can have one of two types: Presta or Schrader – Schrader is the type used by cars and assumed in the description above).
Article Summary X To check the air pressure in your tires, start by looking in the owner’s manual or the inside of the driver’s door for the standard inflation pressure. Next, unscrew the cap from the valve stem on the tire and press the air pressure gauge evenly onto the valve stem.

How do I know which tire needs air?
What to Do –
Pull your car onto a level surface in the shade. Remove dust caps from the tires’ valve stems. Using your tire gauge, firmly press the tip of the gauge straight on to the tire’s valve stem for a brief moment. The tire gauge should provide a psi reading; if the number seems unrealistically low or high — for example, 85 psi or 1 psi – you will need to repeat the previous step, ensuring that the tire gauge’s tip is properly making contact with the valve stem. If the tire gauge’s recorded reading is higher than the manufacturer-recommended rating, press the gauge tip on the valve stem until you hear air leak out. Check the tire pressure again. If the reading is lower than recommended, you will need to fill the tire with air. If you don’t have an air compressor at home, you’ll have to take your car somewhere with one. A gas station is likely to have one, but not all do. Do not drive on a flat tire; it is unsafe and can damage the wheel itself. To fill the tire, firmly press the air-hose tip onto the valve stem. You will hear air quietly enter the tire. If you hear air leaking or spraying out, you need to double-check that the connection between the air hose and the tire’s valve stem is secure. When you think you’ve added or let out enough air, check the pressure a few times with the gauge. Replace the valve dust caps.
Rastetter emphasized the importance of keeping dust caps on during winter driving because if water gets into the valve stem and freezes inside the tire, it could cause a flat. While you’re at it, check your spare tire’s pressure. You don’t want to have a flat tire and then find out your replacement is flat, too.

How do you manually check tire pressure?
4. CHECK TIRE PRESSURE WITH YOUR GAUGE – Remove the valve cap from one of your tires. Then place the pressure gauge on the valve stem and press down hard enough so the hiss sound disappears and your gauge provides a reading. With a standard gauge, the air pressure will push a small bar out from the bottom of the gauge.

How do you check TYRE pressure without gauges?
Feeling the Wheels – This is one of the most common ways to check for tire pressure without a gauge. Also known as hand pressure, it involves pressing the tire using your hand or foot. If the tire feels soft, it means that you need to inflate it. If it feels firm, then it has sufficient pressure and is good for the road. You can rely on this method how to check bike tire pressure without gauge.

Can I drive on low tire pressure?
Is it Safe to Drive? – If your tire pressure is only slightly low, you should be able to drive safely for a few more miles until you can add air. Tire pressure that is extremely low can lead to tire failure. This can result in a blowout, which can be extremely dangerous.
You’ll also experience poor traction and your car won’t be able to properly absorb the impact of the road. This is extremely dangerous in bad weather conditions like rain or snow since your tires will not be able to get a firm grip on the road when you drive and turn corners. The tire pressure light is specifically designed to alert you that there’s an issue with air pressure, so it should not be ignored.
If you don’t check the air, you could be at risk of getting a flat tire. If you experience a blowout, it can cause serious repercussions that can affect your safety, the safety of your passengers, and the safety of other drivers on the road. Stop at a gas station as soon as you can and refill the tires until they reach their proper air levels.

How do I know if my tires are too low to drive on?
If tire pressure is too low and the car drives over bumps and ridges, the car will feel like it’s toppling over them without ease. This is a result of less cushion within the tires’ air chambers. As you drive, see if the car feels like the shock absorbers aren’t working.

How does Mercedes TYRE pressure work?
Mercedes Tyre Pressure Systems Some details about your Mercedes Benz Tpms System. Before the year 2014 most of the Mercedes models had what’s called indirect TPMS (Tyre Pressure Monitoring System) fitted. This system works by taking information from the ABS sensor of the car and notifying the driver when a wheel effectively rotates faster than any of the others ( there’s a little more tech to that, but keeping it simple, when a tyre loses pressure, it reduces in size – like a balloon!! ).
- After 2014 all of the Mercedes Benz models started to have Direct TPMS systems installed, which has an electronic sensor fitted inside the tyre to the base of an aluminium valve (the bit you see sticking our where you feed air into! ).
- This kind of TPMS system measures tyre temperature and pressure in real time and reports back to an onboard computer using a localised radio transmission.
In any abnormal situation (temp or pressure change) the system provides instant information to the occupants. This alert can signify different situations (all require your attention though!). If there is air pressure loss: The system will illuminate on the dashboard a TPMS indicator light.
This light will remain on until the problem is resolved or the air pressure reset. Using the onboard computer menu system, it can then be seen exactly which tyre(s) has the problem! NOTE: it is highly unlikely that a tyre will lose pressure for no reason. ALWAYS have it checked immediately ( we can do this for you with our mobile tyre service in Bristol!!!) It is possible for a sensor malfunction to have occurred too though! They are battery powered with an estimated life of 5-7 years dependent on usage.
When the transmitter fails due to battery depletion, it’ll also trigger the same warning (a TPMS warning light on your dash is an automatic MoT failure too!) Condensation causing excessive moisture within the tyre can lead to advanced corrosion, which could also cause a TPMS sensor malfunction – as can poor tyre fitting and removal or continued use after a blow out or puncture.
In all cases your very best, most convenient and competitive option is to call Hometyre mobile tyre services to check your TPMS system, detect which tyre sensor has a problem and replace it with a new one. We’re equipped with all of the the necessary TPMS diagnostic tools to reset your TPMS system too – saving £££’s on dealer reprogramming costs! Your valves are serviceable items too with internal air seals which require periodic maintenance and replacement.
Carried out as part of routine tyre replacements, these units cost around £8.00 each. If they’re left to fail, the costs are likely to be far far higher! Call Hometyre Mobile Tyre Fitters Bristol. Your local Tyre Pressure Sensor experts! 03334445454 : Mercedes Tyre Pressure Systems

How do I know if my tire pressure sensors?
TPMS is an important vehicle safety feature mandated in the EU, U.S., and China. In the U.S., if a car or light duty vehicle under 10,000 lbs is manufactured after September 1, 2007, the vehicle is required to be equipped with TPMS. Within the TREAD Act of 2000, the U.S. federal government mandated the required implementation of TPMS on all new vehicles in the following phased rollout:
20% of new vehicles from Oct 5, 2005–Aug 31, 2006 70% of new vehicles from Sept 1, 2006–Aug 31, 2007 100% of new vehicles from Sept 1, 2007 and beyond
Prior to the legislation, some higher-end vehicles came equipped with TPMS as a premium option. In the EU, TPMS became mandatory for all class M1 vehicles (vehicles designed and constructed for the carriage of passengers and comprising no more than eight seats in addition to the driver’s seat) registered after November 1, 2014.
The initial legislation was approved in 2009 in Brussels (UN ECE R64) with the aim to optimize fuel consumption and increase driver safety, which are the two most well-known benefits of TPMS systems. The introduction of the current legislation happened with a two-year phase in schedule starting from November 1, 2012.
All vehicle types approved after this date are equipped with TPMS. Furthermore, all newly registered vehicles after November 1, 2014 have TPMS. Worried about compliance with TPMS legislation? There are several easy ways to check whether or not a vehicle comes equipped with direct TPMS.
- The easiest way is to watch the dashboard indicator lights at start-up.
- Turn the vehicle’s ignition switch to the “ON” or “AUX” position, or simply start the vehicle.
- Look for a TPMS warning light on the dashboard.
- Additionally, you can check the vehicle owner’s manual.
- There will be a section inside about TPMS, explaining the functionality of the system and how it works specifically for that vehicle.
Another way to verify if a vehicle is equipped with TPMS is to use a TPMS programming and diagnostic tool to “test” the sensors. Hold the TPMS tool up to the sidewall of the tire just above the exposed valve stem and follow the tool menu structure to check the TPMS sensor status.
