Recommended tire pressure
The tire pressure placard on the driver's side B
pillar (between the front and the rear door) indi-
cates tire pressure for different loads and speed
conditions. The decal specifies the designation for the fac-
tory-mounted tires on the vehicle, as well as load
limits and inflation pressures.

Approved tire pressure (p. 675) Tire pressure monitoring system*
The tire pressure monitoring system 6
provides a
warning symbol in the instrument panel if pres-
sure is too low in one or more tires. Symbol
Explanation This symbol illuminates to indicate
low inflation pressure.
If there is a system malfunction, the
inflation pressure warning symbol
will flash for approximately one
minute and then glow steadily.
System descriptionThe tire pressure monitoring system measures
differences in rotational speed between the
wheels through the ABS system to determine if
the tires are properly inflated. If inflation pressure
in a tire is too low, its diameter (and consequently
its rotational speed) changes. By comparing the
tires with each other, the system can determine if
the pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring
system is generally referred to as TPMS.
Each tire, including the spare (if provided)
7
should be checked monthly when cold and infla- ted to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure.
Driving on a significantly under-inflated tire cau-
ses the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire main-
tenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-infla-
tion has not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
6

||WHEELS AND TIRES
* Option/accessory.
570 pressure telltale. When the system detects a mal-
function, the telltale will flash for approximately
one minute and then remain continuously illumi-
nated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressure
warning symbol is shown in the instrument panel
along with a message.
Tire pressure low Check tires, calibrate
after fill
Tire pressure system Temporarily
unavailable
Tire pressure system Service required
To keep in mind
Always calibrate the system after changing
wheels or adjusting tire pressure. See the tire
pressure placard on the driver's side B pillar
for Volvo-recommended tire pressures.
If you switch to a tire of another size than the
factory-mounted tires, the system must be
calibrated for these tires to avoid false warn-
ings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system will not
work correctly due to the differences
between the wheels.
The system does not replace the need for
regular tire inspection and maintenance.
It is not possible to deactivate the tire pres-
sure monitoring system.
WARNING
Incorrect inflation pressure could lead to
tire failure, which could cause the driver
to lose control of the vehicle.
The system cannot predict sudden tire
damage.

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.. 9

NOTE Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.
If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.
The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide,
which is invisible and odorless but very poi-
sonous. For this reason, always perform the
calibration procedure outdoors or in a work-
shop with exhaust gas evacuation equipment.

When the system for monitoring inflation pres-
sure 13
detects low inflation pressure in a tire,
immediate action is required.
If the system's indicator symbol illumi-
nates and the message Tire pressure
low is displayed, check the tire pres-
sure and inflate if necessary. 1. Switch off the ignition.
2.

Check the inflation pressure on all four tires
using a tire pressure gauge.
3. 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.
4. Through calibration of the system via the center display after the tire pressure has
been adjusted.
Please be aware that the indicator symbol
will not go out until the low tire pressure has
been corrected and the system has been
recalibrated.
NOTE To help prevent incorrect inflation pressure,
pressure should be checked when the tires
are cold. The tires are considered to be cold
when they have reached the same tempera-
ture as the ambient temperature (about 3
hours after the vehicle was last driven). After
driving for a few kilometers, the tires will warm
up and the pressure will increase.
NOTE

After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
WARNING
Incorrect inflation pressure could lead to
tire failure, which could cause the driver
to lose control of the vehicle.
The system cannot predict sudden tire
damage. 11
