The warning light
What the TPMS light means
The TPMS (tire pressure monitoring system) warning light tells you that the system has detected low pressure in at least one tire, or a problem with the system itself. Often the cause is simple, and a few checks are enough to find it.
If a tire looks flat or the vehicle handles strangely, stop in a safe place and do not keep driving.
Before you start
A tire pressure gauge
A reliable gauge, even a small one, is enough.
An air source
A pump or a service station compressor.
Your vehicle manual
It gives the recommended pressures and the TPMS reset procedure for your vehicle.
Step by step
Park and let the tires cool
Check pressures when the tires are cold: after the vehicle has been parked for a few hours, or after a very short drive.
Find the recommended pressure
It is on a label in the driver's door frame, or in the vehicle manual.
Check every tire
Use the gauge on each tire, and on the spare if your vehicle monitors it.
Inflate where needed
Bring each tire to the recommended pressure.
Drive, then check the light
Drive a short distance at normal speed. On many vehicles the light goes out by itself; if not, look for a reset button or a reset entry in the vehicle menu.
When you need a tool
If the light stays on, or if you replaced a sensor or changed tires, the vehicle may need to learn the sensors again. A TPMS tool can read the sensors and help the vehicle learn them again.
