If the pressure remains below 22 psi (1.8 bar) after approximately sev\
en minutes, turn off the
compressor. In this case, the hole is too large to be sealed and the veh\
icle should not be driven.
10. Unscrew the hose from the tire's inflation valve and reinstall the v\
alve cap.
11. Fold down the orange section of the tire sealing system to its origi\
nal (horizontal) position and press
the safety catch into place.
12. Safely stow the tire sealing system kit in a convenient place as it \
will soon be used again to check the
tire's inflation pressure.
13. Immediately drive the vehicle for approximately 2 miles (3 km) to \
distribute the sealing compound in
the tire.

Stage 2 - Checking inflation pressure
1. Park the car in a safe place.
2. Ensure that the orange switch (2) is in position 0 (the 0 side of \
the switch should be pressed down).
3. Remove the valve cap from the tire's inflation valve and screw the ho\
se connector onto the valve as
tightly as possible by hand.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur \
while driving, reduce speed and
park the car in a safe place. Recheck the tire for bumps, cracks, or oth\
er visible damage, and recheck its
inflation pressure. If the pressure is below 16 psi (1.3 bar), do not \
continue driving. Have the vehicle
towed to a workshop or Volvo retailer.
4. Connect the electrical wire to the nearest 12-volt socket in the vehi\
cle.
5. Start the vehicle's engine.
6. Check the tire's inflation pressure on the gauge (9).

After use, return the tire sealing system to its storage compartment beh\
ind the ski hatch in the center of
the rear seat backrest.
WARNING
If you interrupt your trip for more than one hour, check the inflation p\
ressure in the damaged tire again
before continuing. See the section "Stage 2: Checking inflation pressure\
" on
page 154.
Replacing the sealing compound container
The sealing compound container must be replaced if:
l the tire sealing system has been used to repair a tire
l the container's expiration date has passed (see the date on decal 1).
After use, the container (6), its retaining bracket (9), and the hos\
e (10) must be replaced. Please consult
your Volvo retailer for replacement parts.
See also the safety regulations on the bottom of the container.
WARNING
Be sure that the compressor is not connected to a 12-volt socket while r\
eplacing the
container.

179 08 Car care
Washing and cleaning the vehicle
washers do not have facilities for washing the underbody.
CAUTION
l Before driving into an automatic car wash, turn off the optional rain se\
nsor to avoid damaging the
windshield wipers.
l Make sure that side view mirrors, auxiliary lamps, etc, are secure, and \
that any antenna(s) are
retracted or removed. Otherwise there is risk of the machine dislodging \
them.
WARNING
l When the car is driven immediately after being washed, apply the brakes \
several times in order to
remove any moisture from the brake linings.
l Engine cleaning agents should not be used when the engine is warm. This \
constitutes a fire risk.
Exterior lighting
Condensation may form temporarily on the inside of the lenses of exterio\
r lights such as headlights, fog
lights, or taillights. This is normal and the lights are designed to wit\
hstand moisture. Normally,
condensation will dissipate after the lights have been on for a short ti\
me.
Polishing and Waxing
l Normally, polishing is not required during the first year after delivery\
, however, waxing may be
beneficial.
l 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 comp\
ound.
l After polishing use liquid or paste wax.
l Several commercially available products contain both polish and wax.
l Waxing alone does not substitute for polishing a dull surface.
l A wide range of polymer-based waxes can be purchased today. These waxes \
are easy to use and
produce a long-lasting, high-gloss finish that protects the bodywork aga\
inst oxidation, road dirt and
fading.
l Do not polish or wax your vehicle in direct sunlight (the surface of th\
e vehicle should not be warmer
than 113° F (45° C).
CAUTION

dule.

CAUTION
l Not checking the oil level regularly can result in serious engine damage\
if the oil level becomes too
low.
l Oil that is lower than the specified quality can damage the engine.
l Always add oil of the same type and viscosity as already used.
l Never fill oil above the MAX mark. This could cause an increase in oil c\
onsumption.

Engine oil
WARNING
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces
NOTE
Volvo uses different systems to indicate a low oil level or pressure. So\
me models have an oil pressure
sensor, in which case a warning symbol (see
page 48) is used to indicate low oil pressure. Other models
have an oil level sensor, in which case the driver is alerted by the war\
ning symbol in the center of the
instrument panel and a text in the information display. Some models use \
both systems. Contact an
authorized Volvo retailer for more information.

retailer.
NOTE
Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the coolant
and has a lower boiling point. It can also cause damage to the cooling s\
ystem if it should freeze. Top off
with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of water and an\
tifreeze).
CAUTION
The cooling system must always be kept filled to the correct level, and \
the level must be between the
MIN and MAX marks. If it is not kept filled, there can be high local tem\
peratures in the engine which
could result in damage. Different types of antifreeze/coolant may not be\
mixed. Check coolant
regularly!
WARNING
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle cools. If it is necessary
to top off the coolant when the engine is warm, unscrew the expansion ta\
nk cap slowly so that the
overpressure dissipates.

The brake fluid should always be between the MIN and MAX marks on the si\
de of the reservoir. Check,
without removing the cap, that there is sufficient fluid in the reservoi\
r.
Fluid type: DOT 4+ boiling point > 536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in t\
he Warranty and Service
Records Information booklet. When driving under extremely hard condition\
s (mountain driving, etc), it
may be necessary to replace the fluid more often. Consult your Volvo ret\
ailer. Always entrust brake fluid
changing to an authorized Volvo retailer.
Power steering fluid
The fluid level is checked at each service interval.
Fluid type: Volvo power steering fluid or equivalent.
Replace: No fluid change required.
WARNING
If a problem should occur in the power steering system or if the vehicle\
has no electrical current and
must be towed, it is still possible to steer the vehicle. However, keep \
in mind that greater effort will be
required to turn the steering wheel.
