Calibrating the tire pressure
monitoring system*
In order for the tire pressure monitoring system
9
to function correctly, tire pressure reference val-
ues must be set correctly. This must be done
each time the tires are changed or the tire pres-
sure is adjusted.
For example, when driving with a heavy load or at
high speeds (over 160 km/h (100 mph)), tire
pressure should be adjusted to the Volvo-recom-
mended tire pressure values. The system should
then be recalibrated.
1. Switch off the ignition.
2. Inflate the tire to the correct inflation pres-
sure; see the tire pressure placard on the
driver's side B pillar for recommended pres-
sures for factory-mounted tires.
3. Start the vehicle.
4.
Open the
Car Status app in App view.
5.
Tap
TPMS.
NOTE
The car must be stationary when calibration is
started.
6.
Tap
Calibrate.
7.
Tap
OK to confirm that the tire pressure in
all four tires has been checked and adjusted.
8. Run the car until calibration is complete.
Calibration is done when the vehicle is driv-
ing at a speed above 35 km/h (22 mph).
If the car's ignition is switched off before cal-
ibration is complete, the tires in the center
display change color from gray to green upon
next start-up, even if calibration is not com-
plete. Perform the calibration again and allow
it to complete within the same operating
cycle to ensure that the calibration is carried
out correctly.
> When enough data has been collected for
the system to detect low tire pressure, the
color of the tire symbols in the center dis-
play will change from gray to green. The
system will not provide any other confir-
mation that calibration has been comple-
ted.
If start-up of calibration fails, the following
message appears:
Calibration
unsuccessful. Try again..
