•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15
minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
•
CAUTION
•Always use distilled or deionized water
(battery water).
•Never fill above the level mark in the cell.

Changing wheels with TPMSPlease 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 a
trained and qualified Volvo service tech-
nician.
•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.
