CAUTION
After inflating the tires, always reinstall
the valve cap to help avoid damage to the
valve from dirt, gravel, etc.
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
WARNING
Incorrect inflation pressure could lead to
tire failure, resulting in a loss of control of
the vehicle.
Tire monitoring systems cannot indicate
sudden tire damage caused by external
factors (e.g., a blowout) in advance.

Calibrating the Tire Pressure
Monitoring System (TPMS)
In order for the Tire Pressure Monitoring System
to work properly, tire pressure reference values
must be set correctly. This must be done each
time wheels are changed or tire pressures are
modified.
Calibrating TPMS
To calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure.
Consult the tire pressure decal located on
the driver's side B-pillar (the structural mem-
ber at the side of the vehicle, at the rear of
the driver's door opening) or the inflation
pressure table in your printed owner's man-
ual supplement.
3. Start the engine.
4.
Open the
Car status app in the center dis-
play's App view.
5.
Tap
Status to access Tire Pressure
Monitoring System.
6. Tap the calibration button.
7.
Tap
OK after the tire pressure in all four tires
has been checked and adjusted.
8. Drive the vehicle.
> The calibration process will be completed
while driving and will be interrupted if the
vehicle is parked and the engine is
switched off. Calibration continues auto-
matically when driving resumes.
When enough data has been collected to detect
a low tire pressure situation, the tires' color in the
center display will change to green. The system
will not give any text confirmation when calibra-
tion is finished although it will state if calibration
fails. When driving with heavy loads or at sus-
tained highway speeds, the tire pressure should
be adjusted to the recommended inflation pres-
sures.
After adjusting inflation pressure, repeat steps
1-8.
