Oil pressure warning light
If the light comes on while driving, stop the vehicle and then stop the \
engine immediately and
check the engine oil level See
page 130. If the light stays on after restart, have the vehicle towed to the
nearest authorized Volvo retailer. After hard driving, the light may com\
e on occasionally when the
engine is idling. This is normal, provided it goes off when the engine s\
peed is increased.
CHECK ENGINE Malfunction indicator light
On-Board Diagnostics II (OBDII): As you drive, a computer called "OBDI\
I" monitors your vehicle's
engine, transmission, electrical and emission systems. The CHECK ENGINE \
light will light up if the
computer senses a condition that potentially may need correcting. When t\
his happens, please have your
vehicle checked by a Volvo retailer as soon as possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice\
a change in your
vehicle's behavior. Even so, an uncorrected condition could hurt fuel ec\
onomy, emission cleanliness, and
driveability. Extended driving without correcting the cause could even d\
amage other components in
your vehicle.
Canadian models are equipped with this warning light.

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 modeÐenhanced 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 24).
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. 108 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.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legally required in some states/provinc\
es.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.

WARNING!
The ignition system has very high voltage! The voltage in the ignition s\
ystem is dangerous!
Do not touch spark plugs, ignition cables or the ignition coil when the \
engine is running or the
ignition is switched on!
The ignition should be switched off when:
- Conducting engine tests.
- Replacing parts in the ignition system, such as spark plugs, ignition \
coil, distributor, ignition cables,
etc.
- Never try to repair any part of the SRS/ SIPS/WHIPS/IC systems yoursel\
f. Any interference in the
system could cause malfunction and serious injury. Any work should only \
be performed by an
authorized Volvo workshop.
pg. 127 Maintenance
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 requires\
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.

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 ant\
ifreeze 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 wate\
r 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.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F
(30° C), SAE 5W-30 will provide good fuel economy and engine protec\
tion. See the viscosity chart at
right.
Extreme engine operation
Synthetic oils meeting SAE 10W-30 and complying with oil quality require\
ments are recommended for
driving in areas of sustained temperature extremes (hot or cold), when\
towing a trailer over long
distances, and for prolonged driving in mountainous areas.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at
ower request and at additional charge. Please consult your Volvo retaile\
r.
l The API Service Symbol "donut" is divided into three parts:
l The top half describes the oil's performance level.
l The center identifies the oil's viscosity.
l The bottom half tells whether the oil has demonstrated energy-conserving\
properties in a standard test
in comparison to a reference oil.

Oil and fluids (contd)
Checking the oil level
The oil level should be checked every time the vehicle is refueled. This\
is especially important
during the period up to the first maintenance. CAUTION
Not checking the oil level regularly can result in serious engine damage\
if the oil level becomes too
low.
Park the vehicle on a level surface and wait for at least 5 minutes afte\
r the engine has been switched
off. Be sure the oil level is maintained between the upper and lower mar\
ks on the dipstick. Low oil
level can cause internal damage to the engine and overfilling can result\
in high oil consumption. The
distance between the dipstick marks represents approx. 1.6 US qt (1.5 l\
iter). The oil should preferably
be checked when cold, before the engine has been started.
NOTE: The engine must be stopped when checking the oil.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.
Adding oil (topping up)
l Add oil of the same kind as already used.

- If it is necessary to top up the coolant when the engine is warm, unsc\
rew the expansion tank cap
slowly so that the overpressure dissipates.

Brake fluid reservoir
The brake fluid should always be above the MIN mark on the side of the r\
eservoir. Check, without
removing the cap, that there is sufficient 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 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.
Power steering fluid reservoir
The fluid level should always be between the MIN and MAX marks. Fluid type : ATF
