properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
Resetting and recalibrating the benchmark tire pressure
Resetting the tire pressures in the Infotainment system resets the benchmark tire pressure used by
the TPMS to the current tire pressure in the tires based on the circumference of the tires.
Switch on the ignition.
Press the Infotainment button ⇒Infotainment system operation and displays .
Tap the Vehicle and function keys to open the Vehicle settings menu.
Tap the Tires function key.
Tap the SET function key in the Tire Pressure Monitoring System menu.
If all 4 wheels are set to the correct values, touch the Confirm function key to store the tire
pressures.
Touching the Cancel button will prevent the current tire pressures from being stored and the sys‐
tem will not be recalibrated.
The recalibration must be performed each time the tire pressure in one or more tires has been ad‐
justed or after one or more tires has been changed, exchanged, or repaired. The new tire pressures
are stored in the system only after at least 20minutes of normal driving.
If you have reset the benchmark tire pressure when your tires do not have the correct tire pressure,
this will prevent the TPMS from working properly. It may then give false warnings or may not give any
warning even if the tire pressure is too low.
For this reason, it is vital to make certain that all 4tires are inflated to the correct pressure
when they are cold before calibrating the system. Cold tires are tires that have not been driven
more than a couple of miles (kilometers) at low speed within the last 3hours.
During normal vehicle operation, the system calibrates itself to the tires installed and the changed tire
pressures. The calibrated values are stored and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, for example, if the vehicle is carrying heavy load,
the tire pressure must be raised to the recommended full-load tire pressure before recalibaration
