Find the service button on your screen, you might have to scroll down. Once you click on the ‘service’ button, find ‘tire pressure’ and select it. This will actually display what your tire pressures are. Once you adjust to the correct pressure, you can reset the
TPMS light
.
The TPMS reset button is usually located
beneath the steering wheel
. If you are unable to find it, refer to your vehicle’s owner’s manual. Inflate all tires to 3 PSI over their recommended amount, then deflate them completely.
How do you reset the low tire pressure light?
Turn the car key to “on” but don’t start the vehicle.
Press and hold the TPMS reset button
until the tire pressure light blinks three times. Release the button and start the car. The light should go off within 20 minutes.
Why won’t my low tire pressure light go off?
Without starting the car, turn the key to the “On” position. Press the
TPMS reset button
and hold it until the light blinks three times, then release it. Start the car and let it run for 20 minutes to reset the sensor. You’ll usually find the tire pressure monitor reset button beneath the steering wheel.
How do Mercedes Benz tire pressure sensors work?
The sensor transmits that
information via low-frequency radio to the vehicle’s onboard computer
and, if the car has one, to a corresponding display in the instrument cluster. It reads out in pounds per square inch (psi), and it illuminates an amber warning light to alert you if one or more tires are low on air.
Why is my tire pressure light on but my tires are fine?
In most cases, the warning light may be triggered by a tire that is
10% to 15% low in air pressure
. Cold or icy weather also has a tendency to lower the air pressure inside the tires. Taking the car for a short drive will heat up the tires and increase the tire pressure.
Is it normal for tires to lose pressure?
About 1-3 psi per month is normal for air loss
, but you still should check inflation rates often, and re-inflate your tires. Neglecting tire inflation for 6 months may take out 6-18 psi, and with the most frequent recommended rate being 30-35 psi, this is a big loss.
The TPMS reset button is usually located

What should I do if my tire pressure is low?
If too low, continue to add air in short bursts and recheck. If you add too much air, let some out by pressing the pin in the center of the tire valve with the back of the air hose nozzle or your tire gauge. Generally, the tire will let out approximately one
psi for every three seconds the
pin is depressed.
Why is my TPMS not working?
TPMS problems can include any of the following: …
The TPMS module itself is not functioning properly
or has failed because of a voltage supply, wiring or internal electronics fault. • The tires were serviced or rotated recently and the relearn procedure was not done correctly.
How much air should be in a Mercedes tire?
As a rule of thumb, tire pressure should usually be
between 32-36 PSI
. Check your owner’s manual for exact numbers, as these can vary from model to model.
What PSI should my Mercedes Tyres be?
You don’t want to underinflate or overfill your tires. For example, a reasonable range for Mercedes-Benz vehicles is
30-35 PSI
. If you inflate your tires to less than 30 PSI, your fuel efficiency will decrease.
How long do Mercedes TPMS sensors last?
The lithium ion batteries inside TPMS sensors may last anywhere from
five to 10 years
. Five to six years is a more typical lifespan for older TPMS sensors. The lithium ion batteries inside TPMS sensors may last anywhere from five to 10 years. Five to six years is a more typical lifespan for older TPMS sensors.
Why is my tire pressure light on when my tires are fine Honda Civic?
The reason you have a tire pressure monitoring system in your Civic is
to detect a flat tire
. Or possibly more than one flat tire. If the light comes on while you are driving, this is the likely cause. … Use a tire gauge to check the pressure in all four of the vehicle’s tires.
Is it safe to drive with tire pressure light on?
It’s not safe to drive around with your TPMS light illuminated
. Without a tire inspection, there’s no way of knowing how quickly air is leaving your tire, or for how long it has been over or underinflated. The best course of action is to use a tire pressure gauge to check the current inflation level of each tire.
What can cause your tire pressure light to come on?
When the tire pressure monitoring system (TPMS) light on your dash comes on, it usually means that the air pressure in one or more of your tires has dropped below the expected level. The light can also be triggered
erroneously by a bad sensor
, and it can also come on, and go back off, seemingly at random.
