Condensation on the inside of the
windows
Keeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Cabin air filter
Replace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof* for several minutes before driving
will help release the warm air from the passen-
ger compartment. When the engine is running,
close the windows and moonroof and use the
recirculation function for several minutes to
enable the air conditioning to cool the com-
partment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
8-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

Cold weather precautions

163
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 protect your vehicle dur-
ing 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 section "Engine
oil" 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 antirust oil on
the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving – see
section "Wheels and tires."
•To prevent the washer fluid reservoir
from freezing, add washer solvents con-
taining antifreeze (see page 217 for the
location of the washer fluid reservoir). This
is important since dirt is often splashed on
the windshield during winter driving,
requiring the frequent use of the washers
and wipers. Volvo Washer Solvent should
be diluted 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 sol-
vent and 2 parts 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 the use of de-icing sprays as they can
cause damage to the locks.
W – Winter/Wet driving mode – enhanced
vehicle traction
•Mode W will only function if the gear selec-
tor is in the (D)rive position.
•Press the button at the base of the gear
selector to engage/disengage this driving
mode.
•An LED in the button will light up to indicate
that W is engaged and this will also be dis-
played in the instrument panel (see
page 58).
•This mode may be selected for starting/
moving off on slippery roads.
1Synthetic oil is not used when the oil is changed at the normal maintenance service intervals except at owner request and at additional charge. Please consult your Volvo retailer.

Maintaining your vehicle09

209 Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.
Each time the vehicle is refueled
•Check the engine oil level
•Clean the windshield, windshield wipers,
headlights, and tail lights
Monthly
•Check cold tire pressure in all tires. Inspect
the tires for wear.
•Check that engine coolant and other fluid
levels are between the
indicated "min" and "max" markings.
•Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•Wipe driver information displays with a soft
cloth.
•Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult a trained
and qualified Volvo service technician for
additional information.
As needed
•Wash the vehicle, including the undercar-
riage, to reduce wear that can be caused
by a buildup of dirt, and corrosion that can
be caused by salt residues.
•Clean leaves and twigs from air intake
vents at the base of the windshield, and
from other places where they may collect.

Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type ofinspection has replaced the tailpipe emission
test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec-
tion for any of the following reasons.
•If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
•If your vehicle's Check Engine light was lit,
but went out without any action on your
part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending
on the inspection practices in your area.
•If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
•If your Check Engine (MIL) light is lit – or
was lit but went out without service, have
your vehicle diagnosed and, if necessary,
serviced by a qualified Volvo technician.
•If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a
period of driving is necessary to bring the
OBD II system to "ready" for inspection. A
half-hour trip of mixed stop-and-go/high-

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.

CAUTION
Not checking the oil level regularly can result
in serious engine damage if the oil level
becomes too low.
•Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
•Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•Always add oil of the same type and
viscosity as already used.
WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces.

217 Washer fluid reservoir
G027097
Washer fluid reservoir
The washer fluid reservoir is located in the
engine compartment and holds approx.
6.8 US qts (6.5 liters).
When there is less than approximately 1 US qt
(1 liter) remaining in the reservoir, the washer
fluid spray will be directed to the windshield
only.
During cold weather, the reservoir should be
filled with windshield washer solvent contain-
ing antifreeze.
Changing coolant
G027087
Coolant reservoir
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.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•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 temperatures in the
engine which could result in damage.
Check coolant regularly!
•Do not top up with water only. This
reduces the rust-protective and anti-
freeze qualities of the coolant and has a
lower boiling point. It can also cause
damage to the cooling system if it
should freeze.
•Do not use chlorinated tap water in the
vehicle's cooling system.

WARNING
•Never remove the radiator cap while the
engine is warm. Wait until the vehicle
cools.
•If it is necessary to top up the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid reservoir
G000000
The brake fluid should always be above the
MIN mark on the side of the reservoir. Check,
without removing the cap, that there is suffi-
cient fluid in the reservoir.Fluid type: DOT 4+ boiling point >536 °F
(>280 °C), P/N 9437433.
Replace: Every second year or 30,000 miles
(48,000 km). The fluid should be replaced once
a year or every 15,000 miles (24,000 km) when
driving under extremely hard conditions
(mountain driving, etc.).
Always entrust brake fluid changing to a
trained and qualified Volvo service technician.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•Dot 4+ should never be mixed with any
other type of brake fluid.
Power steering fluid reservoir
FULL
ADD
G026991

ADD and FULL marks.
Fluid type: Volvo synthetic power steering fluid
(Pentosin CHF 11S) P/N 1161529 or equiva-
lent.
Replace: No fluid change required.
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.
