07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
07
192
NOTE
•
TPMS indicates low tire pressure but
does not replace normal tire mainte-
nance. For information on correct tire
pressure, please refer to the tables
beginning, see page 172, 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 pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure 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
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
tables, see page 172 ).
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 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.
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
recommended 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 sen-
sor is moved to another wheel, the sen-
sor's seal, nut, and valve core should be
replaced.
•
When installing TPMS sensors, the
vehicle 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.
