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-
way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.

Maintain your vehicle in accordance with
your vehicle's maintenance schedule.

The ignition should always be completely
switched off before performing any opera-
tions in the engine compartment.
The distributor ignition system operates at
very high voltages. Special safety precau-
tions must be followed to prevent injury.
Always turn the ignition off when:•
Replacing distributor ignition compo-
nents e.g. plugs, coil, etc.
•
Do not touch any part of the distributor
ignition system while the engine is run-
ning. This may result in unintended

06 Maintenance and specificationsEngine oil
06220
Checking the engine oilThe oil level should be checked every time the
vehicle is refueled. This is especially important
during the period up to the first scheduled
maintenance service.•
See page 272 for oil specifications.
•
Refer to the Warranty and Service Records
Information booklet for information on the
oil change intervals.
Volvo recommends Castrol oil products.CAUTION
•
Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•
Oil that is lower than the specified qual-
ity can damage the engine.
•
Volvo does not recommend the use of
oil additives.
•
Always add oil of the same type and
viscosity as already used.
•
Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
Checking and adding oil

Location of the filler cap and dipstick
NOTE
Before checking the oil:•
The car should be parked on a level sur-
face when the oil is checked.
•
If the engine is warm, wait for at least
10 – 15 minutes after the engine has
been switched off before checking the
oil.
G021737
The oil level must be between the MIN and MAX
marks on the dipstickChecking the oil1. Pull out the dipstick and wipe it with a lint-
free rag.
2. Reinsert the dipstick, pull it out, and check
the oil level. The level must be between the
MIN and MAX marks.
3. Add oil if necessary. If the level is close to
theMIN mark, add approximately
0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if nec-
essary until the level is near the MAX mark.

WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces.

Coolant
G021738
Location of the coolant reservoirNormally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
See page 274 for information on cooling sys-
tem capacities.
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
vehicles cooling system.
WARNING
•
Never remove the radiator cap while the
engine is warm. Wait until the vehicle
cools.
•
If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid
