are used more often. Moreover, the capacity of the battery decreases as \
the temperature drops. In very
cold weather, a poorly charged battery can freeze and be damaged. It is \
therefore advisable to check the
state of charge more frequently and spray an antirust oil on the battery\
posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels
and tires."
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see
page 147 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 d\
iluted 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 solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water \
l 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
l Mode W will only function if the gear selector is in the (D)rive position.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and thi\
s will also be displayed in the
instrument panel (see
page 22).
l This mode may be selected for starting/moving off on slippery roads.
* Synthetic oil is not used when the oil is changed at the normal mainte\
nance intervals except at owner request and at additional
charge. Please consult your Volvo retailer.

pg. 109 Starting and driving
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer\
before driving long distances.
Your retailer will also be able to supply you with bulbs, fuses, spark p\
lugs 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\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage
l Check transmission oil level*.
l Check condition of drive belts.
l Check state of the battery's charge.

Owner maintenance
Periodic maintenance requirements and intervals are described in your ve\
hicle's Warranty and Service
Records Information booklet.
The following points can be carried out between the normally scheduled m\
aintenance services.
Each time the car is refueled:
l Check the engine oil level
l Clean the windshield, windshield wipers, headlights, and tail lights
Monthly:
l Check cold tire pressure in all tires. Inspect the tires for wear.
l Check that engine coolant and other fluid levels are between the indicat\
ed "min" and "max" markings.
l Clean interior glass surfaces with a glass cleaner and soft paper towels\
.
l Wipe driver information displays with a soft cloth.
l Visually inspect battery terminals for corrosion. Corrosion may indicate\
a loose terminal connector, or
a battery near the end of its useful service life. Consult your Volvo re\
tailer for additional information.
As needed:
l Wash the car, including the undercarriage, to reduce wear that can be ca\
used by a buildup of dirt, and
corrosion that can be caused by salt residues.
l Clean leaves and twigs from air intake vents at the base of the windshie\
ld, 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 diagnostic
information about your vehicle's emission controls. It can light the Che\
ck 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 messag\
e 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. Th\
e inspector can then read
"faults." In some states, this type of inspection has replaced the tailp\
ipe emission test.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection for any of the followin\
g reasons.
l If your Check Engine (MIL) light is lit, your vehicle may fail inspect\
ion.
l If your vehicle's Check Engine light was lit, but went out without any a\
ction 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.
l If you had recent service that required disconnecting the battery, OBD I\
I diagnostic information may
be incomplete and "not ready" for inspection. A vehicle that is not read\
y may fail inspection.
How can I prepare for my next OBD II emission inspection?
l If your Check Engine (MIL) light is lit - or was lit but went out with\
out service, have your vehicle
diagnosed and, if necessary, serviced by a qualified Volvo technician.
l 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/ highway driving is ty\
pically needed to allow OBD II
to reach readiness. Your Volvo retailer can provide you with more inform\
ation on planning a trip.
l Maintain your vehicle in accordance with your vehicle's maintenance sche\
dule.

Working you your vehicle

Reinforced lifting points
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments p\
oints should be used. They are
specially reinforced to bear the weight of the vehicle (see the illustr\
ation above). A garage jack can also
be placed under the front of the engine support frame. Take care not to \
damage the splash guard under

Battery Maintenance
The battery in your vehicle is located under the floor of the cargo comp\
artment.
Driving habits and conditions, climate, the number of starts, etc. all a\
ffect the service life and function of
the battery. In order for your battery to perform satisfactorily, keep t\
he following in mind:
l Check the fluid level in each cell in the battery every 24 months or eve\
ry 15,000* miles (24,000 km),
whichever is sooner. The fluid should be at the level shown in the illus\
tration above (A)**.
l Use a screw driver to open the caps and a flashlight to inspect the leve\
l.
l If necessary, add distilled water. The level should never be above the i\
ndicator (A**).
l The fluid level should be checked if the battery has been recharged.
l After inspection, be sure the cap over each battery cell is securely in \
place.
l Check that the battery cables are correctly connected and properly tight\
ened. Route ventilation hose
through opening in floor (see
page 151)
l Never disconnect the battery when the engine is running, for example whe\
n changing the battery.
l The battery should be disconnected from the vehicle when a battery charg\
er is used directly on the
battery.
l However, if the battery is being charged via the connecting points in th\
e engine compartment (see
page 103), the battery must be connected.
* More frequently in warm climates.
** The level indicator inside the battery could be designed in various w\
ays. See illustration.
