Introduction to the subject
In this chapter you will find information on the following subjects:
⇒Indicator light (telltale)
⇒Recalibrating the Tire Pressure Monitoring System (TPMS)
Your vehicle's Tire Pressure Monitoring System (TPMS) uses the Anti-lock Brake System (ABS) sen‐
sors to indirectly check the tire pressure of all 4tires while you are driving. The sensors monitor the
tread circumference (rolling circumference) and vibration characteristics of the individual tires. TPMS
warns if there is a significant loss of pressure in one or more tires while the vehicle is moving.
Pressure loss is signaled by the indicator light (described below) as well as by acoustic warnings
and text warnings in the instrument cluster display if your vehicle has this display Infotainment system
or the Multi-Function Display (MFD).
The original benchmark pressure is the recommended maximum load cold tire inflation pressure for
the tires that come with your vehicle. This pressure is listed on the tire pressure label on the driver
door jamb ⇒Tire inflation pressure . After adjusting the tire pressures in all 4tires, you must confirm
and store the new cold inflation pressures through the Infotainment system, which changes the
benchmark pressure to match the current pressure of the tires on your vehicle ⇒Recalibrating the
Tire Pressure Monitoring System (TPMS) .
Recalibrating the TPMS to reset the benchmark cold tire inflation pressure is explained on
⇒Recalibrating the Tire Pressure Monitoring System (TPMS) .
WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, colli‐
sion, serious personal injury or even death.
When the warning symbol appears in the instrument cluster, stop and inspect the tires.
Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the
handling of the vehicle and stopping ability.
Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, including a
blowout and sudden deflation, causing loss of vehicle control.
The driver is responsible for the correct tire pressures for all tires on the vehicle. The recom‐
mended tire pressure values are listed on a sticker inside the driver door ⇒Tire inflation pres‐
sure .
