06 Maintenance and specifications
Wheels and tires
NOTE
• TPMS indicates low tire pressure but
does not replace normal tire maintenance.
For information on correct tire pressure,
please refer to the tables beginning on
page 217, or consult your Volvo retailer.
• The tire pressure warning light will not
identify which tire is underinflated. Be sure
to check all four tires.
• A certain amount of air seepage from the
tires occurs naturally and tire pressure fluc-
tuates with seasonal changes in tempera-
ture. Always check tire pressure regularly.
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
06
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres-
sure (consult the tire pressure placard or
the tables beginning on page 217).
3. In certain cases, it may be necessary to
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
mounted on the vehicle, TIRE PRESS
SYST SERVICE REQUIRED will be dis-
played each time the vehicle is driven
above 25 mph (40 km/h) for 10 minutes or
more.
• Once TPMS sensors are properly in-
stalled, the warning message should not
reappear. If the message is still displayed,
drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster to
erase the message.
• 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 you change to tires with a different rec-
ommended inflation pressure, the TPMS
system must be recalibrated to these tires.
This must be done by an authorized Volvo
retailer or workshop.
• 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 re-
placed.
• When installing TPMS sensors, the vehi-
cle must be parked for at least 15 minutes
with the ignition off. if the vehicle is driven
within 15 minutes, a TPMS error message
will be displayed.
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.
