Belt check
Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and require\
s no adjustment
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 a\
t 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 eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and an\
tifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/ 50 mix of wat\
er and antifreeze). CAUTION!
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, and A\
CEA A1/ B1. Lower
quality oils may not offer the same fuel economy, engine performance, or\
engine protection.

CAUTION!
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge 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 pip\
e
surfaces.
R-models
R-models are equipped with an oil level warning system. If the engine oi\
l level becomes too low, the
warning light in the instrument panel will come on and a warning will be\
displayed in the text window.
l If the yellow warning light in the instrument panel comes on and the tex\
t OIL LEVEL LOW/FILL
OIL is displayed, stop safely as soon as possible and add 1 qt (1 liter\
) of oil. Check the oil level with the
dipstick before restarting the engine.
l If the red warning light in the instrument panel comes on and the text O\
IL LEVEL LOW/STOP
SAFELY-->STOP ENGINE -->SEE MANUAL is displayed, stop safely as soon as \
possible and add oil
(not more than 1.6 qts (1.5 liters). Check the oil level with the dip\
stick before restarting the engine. If no
oil level is visible on the dipstick, do not start the engine. Have the \
vehicle towed to an authorized Volvo
retailer.

Clutch and brake fluid reservoir
The clutch and brake fluid should always be above the MIN mark 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: Every second year or 30,000 miles (48,000 km). The fluid should be rep\
laced once a year or
every 15,000 miles (24,000 km) when driving under extremely hard condi\
tions (mountain driving, etc.).
Always entrust brake fluid changing to an authorized Volvo retailer.

Replacing the battery
- Switch off the ignition and remove the key.
- Wait at least 5 minutes after switching off the ignition before discon\
necting the battery so that all
information in the vehicle's electrical system can be stored in the cont\
rol modules.
- Remove the bolts on the retaining bracket over the battery and lift ou\
t the bracket.
- Fold up the plastic cover over the negative (ground) battery termina\
l. or unscrew the cover over the
battery.
- Disconnect the negative cable.
- Lift off the plastic cover if necessary and disconnect the positive ca\
ble.
- Pull the ventilation hose from the battery.
- Lift out the old battery.
Installing a new battery
- Put a new battery into place.
- Put the lower retaining bracket in place and retighten the bolt.
- Reconnect the positive cable.
- Press the cover for the positive battery terminal into place and fold \
down the lid of the plastic cover.
- Connect the negative (ground) cable and fold down the plastic cover \
if applicable.
- Be sure that the ventilation hose is securely connected to the battery\
and that the other end of the hose
is properly routed through the ventilation opening in the floor of the b\
attery compartment (see the
illustration).
- Reinstall the retaining bracket over the battery and retighten the nut\
s.
WARNING!
Ventilation hose:
l The battery generates hydrogen gas, which is flammable and explosive. Th\
e battery is fitted with a
ventilation hose which vents hydrogen gas out of the battery compartment\
through a ventilation
opening in the bottom of this compartment. If the battery must be replac\
ed, it is essential that the
ventilation hose is properly connected to the battery and that it is rou\
ted through the ventilation
opening provided (see illustration).
l Be sure the ventilation hose is free of debris.
l Only use replacement batteries equipped with a ventilation hose. Consult\
your Volvo retailer.
NOTE: After the battery has been disconnected or replaced, lock and unlock th\
e vehicle with the central
locking system's remote control to reactivate such features as the power\
windows, moonroof, courtesy
lighting, etc.

Replacing bulbs
When replacing bulbs, keep the following points in mind:
l Never touch the glass of bulbs with your fingers. Grease and oils from y\
our fingers vaporize in the
heat and will leave a deposit on the reflector, which will damage it.
l The optional Active Bi-Xenon headlight bulbs contain trace amounts of me\
rcury. These bulbs should
always be disposed of by an authorized Volvo retailer.
l The following bulbs should only be replaced by an authorized Volvo servi\
ce technician:
- Active Bi-Xenon headlights,
- Courtesy (dome) lighting,
- Reading lights,
- Glove compartment lights
- Turn signals and courtesy lights in the side door mirrors
- High-mounted brake lights
- Diodes in the rear tail lights
Replacing bulbs at the front of the vehicle
All front bulbs (except the optional front fog lights) are replaced fr\
om the engine compartment.
WARNING!
Active Bi-Xenon headlights (option) - due to the high voltage used by \
these headlights, these bulbs
should only be replaced by an authorized Volvo service technician.
