13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
14. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged tire's inflation pressure.
NOTE
•Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.
•The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.
WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tables for the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air from
the tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.
Replacing the sealing compound
container
The sealing compound container must be
replaced if:
•the tire sealing system has been used to
repair a tire
•the container’s expiration date has passed
(see the date on decal).
NOTE
•After use, the sealing compound bottle,
the hose, and certain other system
components must be replaced. Please
consult your Volvo retailer for replace-
ment parts.
•If the sealing compound bottle’s expi-
ration date has passed, please take it to
a Volvo retailer or a recycling station
that can properly dispose of harmful
substances.

Inflating tires
The tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
6. Start the vehicle’s engine.
WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem.
•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation tables for the cor-
rect inflation pressure. If the tire needs to
be inflated, start the tire sealing system’s
compressor (press the on/off switch to
position I). If necessary, release air from the
tire by turning the air release knob coun-
terclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
9. Turn off the compressor (press the on/off
switch to position 0) when the correct infla-
tion pressure has been reached.
10. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
11. Disconnect the electrical wire from the 12-
volt socket.

07 Wheels and tires
Tire Pressure Monitoring System (TPMS) – U.S. models only
07

189
The tire pressure monitoring system uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is mov-
ing at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.
USA – FCC ID: MRXG403MA4A
This device complies with part 15 of the FCC
rules. Operation is subject to the following
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received,
including interference that may cause unde-
sired operation.
When low inflation pressure is detected,
TPMS will light up the tire pressure warning
light (also referred to as a telltale) in the
instrument panel (see page 57), and will dis-
play a message in the text window. The
wording of this message is determined by
the degree of inflation pressure loss.
AOn certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS
will light up the tire pressure warning light
(also referred to as a telltale) in the instrument
panel and will display one of the following mes-sages in the text window:
LOW TIRE PRESS.
CHECK TIRES or VERY LOW TIRE
PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated 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 pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuelefficiency 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 maintenance, and it is the driv-
er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination 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 malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, 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 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 tables or
consult your Volvo retailer.
Erasing warning messagesWhen 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 171).
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 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.
•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.

08 Car care
Washing and cleaning the vehicle
08

195
CAUTION
•Avoid waxing or polishing plastic or rub-
ber components
•Polishing chromed strips can wear
away or damage the surface
•Polishes containing abrasive sub-
stances should not be used
NOTE
When washing the vehicle, remember to
remove dirt from the drain holes in the doors
and sills.
WARNING
•When the vehicle is driven immediately
after being washed, apply the brakes
several times in order to remove any
moisture from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Automatic washing – simple and quick
•We do NOT recommend washing your
vehicle in an automatic wash during thefirst six months (because the paint will not
have hardened sufficiently).
•An automatic wash is a simple and quick
way to clean your vehicle, but it is worth
remembering that it may not be as thor-
ough as when you yourself go over the
vehicle with sponge and water. Keeping
the underbody clean is most important,
especially in the winter. Some automatic
washers do not have facilities for washing
the underbody.
•Before driving into an automatic car wash,
make sure that side view mirrors, auxiliary
lamps, etc, are secure, and that any
antenna(s) are retracted or removed. Oth-
erwise there is risk of the machine dislodg-
ing them.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or tail lights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based car waxes
can be purchased today. These waxes are
easy to use and produce a long-lasting,
high-gloss finish that protects the body-
work against oxidation, road dirt and fad-
ing.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113° F (45° C).

Note the following before you begin working
on your vehicle:
Battery
•Ensure that the battery cables are correctly
connected and tightened.
•Never disconnect the battery when the
engine is running (e.g., when replacing the
battery).
•Never use a fast charger to charge the bat-
tery. The battery cables should be discon-
nected when recharging.
•The battery contains acid that is both cor-
rosive and poisonous. It is important that
the battery is handled in an environmen-
tally friendly way. See page 214 for more
information on handling the battery.
Hoisting the vehicle
G027001
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.
They are specially reinforced to bear the weight
of the vehicle (see the illustration). A garage
jack can also be placed under the front of the
engine support frame. Take care not to dam-
age the splash guard under the engine. Ensure
that the jack is positioned so that the vehicle
cannot slide off it. Always use axle stands or
similar structures. The vehicle's gross vehicle
weight is between 5770 lbs (2630 kg) and
6080 lbs (2760 kg). Use a jack and stands rated
for this weight.If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
WARNING
The ignition system has very high voltage!
The voltage in the ignition system is dan-
gerous!
Do not touch spark plugs, ignition cables or
the ignition coil when the engine is running
or the ignition is switched on!
The ignition should be switched off when:
•Conducting engine tests.
•Replacing parts in the ignition system,
such as spark plugs, ignition coil, dis-
tributor, ignition cables, etc.
WARNING
Never try to repair any part of the SRS/
SIPS/WHIPS/IC systems yourself. Any
interference in the system could cause mal-
function and serious injury. Any work should
only be performed by an authorized Volvo
workshop.

Belt check
Check the belt regularly to make sure it is in
good condition and is clean. A worn or dirty belt
can cause poor cooling and low alternator out-
put as well as impair the operation of the power
steering and the air conditioning unit.
NOTE
The drive belt is equipped with a self-ten-
sioning mechanism and requires no adjust-
ment between changes.
WARNING
The engine must not be running when this
check is performed.
Check coolant level
The cooling system must be filled with coolant
and not leak to operate at maximum efficiency.
Check the coolant level regularly. The level
should be between the MAX and MIN marks
on the expansion tank. The check should be
made with particular thoroughness when the
engine is new or when the cooling system has
been drained.
Do not remove the filler cap other than for top-
ping up with coolant. Frequent removal may
prevent coolant circulation between the engineand the expansion tank during engine warm up
and cooling.
Changing coolant
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
Do not top off with water only. This reduces the
rust-protective and antifreeze qualities of the
coolant and has a lower boiling point. It can
also cause damage to the cooling system if it
should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water
and antifreeze.
CAUTION
The cooling system must always be kept
filled to the correct level. If it is not kept filled,
there can be high local temperatures in the
engine which could result in damage. Dif-
ferent types of antifreeze/coolant may not
be mixed.
WARNING
Never remove the radiator cap while the
engine is warm. Wait until the vehicle cools.
