WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 9 in. (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•If the engine has been stopped while the
car is in water, do not attempt to restart
the engine. Have the car towed out of
the water.
Cold weather precautions
If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to –31 °F
(–35 °C). See section "Coolant". The use of
"recycled" antifreeze is not approved by
Volvo. Different types of antifreeze must
not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to help protect your vehicle
during cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard drivingor in warm weather, see page 274 for more
information.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving – see
the chapter "Wheels and tires."
•To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze (see page 218 for the location of
the washer fluid reservoir). This is impor-
tant since dirt is often splashed on the
windshield during winter driving, requiring
the frequent use of the washers and wip-
ers. Volvo Washer Solvent should be dilu-
ted as follows: Down to 14 °F (–10 °C):
1 part washer solvent and 4 parts water
Down to 5 °F (–15 °C): 1 part washer sol-
vent and 3 parts water Down to 0 °F
(–18 °C): 1 part washer solvent and 2 parts
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer.

water Down to –18 °F (–28 °C): 1 part
washer solvent and 1 part water.
•Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de-icing sprays as they can
cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid turn-
ing the ignition key to position II. Many
electrical systems (the audio system, the
optional navigation system, power win-
dows, etc) will function with the ignition key
in position I. This position reduces drain on
the battery.
•Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained. Driving or having the engine run-
ning for approximately 15 minutes will help
keep the battery charged.
•The optional 12 volt socket in the trunk
(certain models only) provides electricalcurrent even with the ignition switched off,
which drains the battery.
NOTE
•If the ignition is switched on, a warning
message will be displayed in the text
window in the instrument panel when
the battery charge is low.
•An energy conserving function
designed into the vehicle's electrical
system will switch off certain functions
or reduce the load on the battery by,
e.g., reducing the audio system's vol-
ume.
Before a long distance trip
It is always worthwhile to have your vehicle
checked at a trained and qualified Volvo serv-
ice technician before driving long distances.
Your trained and qualified Volvo service tech-
nician will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be
checked before any long trip:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage
•Have the transmission oil level checked2.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by your
Volvo retailer only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with your Volvo retailer if you
intend to drive in countries where it may be
difficult to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
2To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid level inspected by a qualified Volvo service technician.

4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 152, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park and apply the
parking brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 162 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
