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 inflation pres-
sures are modified.
Calibrating TPMS
To calibrate the system:
1. Switch off the engine. The vehicle must be at
a standstill when calibration is started.
2. Re-inflate the tire(s) to the correct pressure.
Consult the tire pressure placard 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 manual
supplement.

3. Start the engine.
4. Open the
Car status
app in the center dis-
play's App view.
5. Tap
TPMS
to access Tire Pressure
Monitoring System.
6. Tap
Calibrate
.
7. Tap
OK
to confirm that the tire inflation pres-
sure has been checked and adjusted in all
four tires.
8. Drive the vehicle.
> Calibration is performed when the vehicle
is driven at a speed of at least 22 mph
(35 km/h) and will be interrupted if the
vehicle is parked and the engine is
switched off. Calibration continues auto-
matically in the background 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.
