ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.
NOTE
TPMS indicates low tire pressure but does
not replace normal tire maintenance. For
information on correct tire pressure, please
refer to the tire inflation pressure table in this
chapter or consult your Volvo retailer.
Erasing warning messages
When a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:
1. Use a tire pressure gauge to check the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
table see page 177).
3. Drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and the
warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Changing wheels with TPMS
Please note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:
Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
If wheels without TPMS sensors are moun-
ted on the vehicle,
TIRE PRESS SYST
SERVICE REQUIRED
will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed,
the warning message should not reappear.
Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.
Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.
NOTE
If a tire is changed or if the TPMS sensor is
moved to another wheel, the sensor’s seal,
nut and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press
the pump's mouthpiece straight onto the
valve to help avoid bending or otherwise
damaging the valve.
Recalibrating TPMS (Canadian models
only)
In certain cases, it may be necessary to reca-
librate TPMS to conform to Volvo's recom-
mended tire inflation pressures (see the infla-
tion pressure table on page 177), for example,
if higher inflation pressure is necessary when
transporting heavy loads, etc.
To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure and
turn the ignition key to position I or II (see
page 141 for additional information).
3. Turn the thumb wheel on the left-side
steering wheel lever until
Tire pressure
Calibration
appears in the display.
4.
Press and hold the Reset button on the
left-side steering wheel lever until
TIRE
PRESSURE CALIBRATED
is displayed.
