Engine compartment, overview
G018945
The appearance of the engine compartment
may vary depending on engine model.
Coolant expansion tank
Power steering fluid reservoir
Engine oil dipstick
Radiator
Filler cap for engine oil
Cover over brake fluid reservoir
Battery
Relay and fuse box
Washer fluid reservoir
Air cleaner
WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.
WARNING
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
movements and body injury.

Coolant
Location of the 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.
See page 277 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
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the
round cover at the rear of the engine compart-
ment. The round cover must be removed first
before the reservoir cap can be accessed.

06 Maintenance and specifications
Fluids

221
The brake fluid should always be between the
MIN and MAX marks on the inside of the res-
ervoir. 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: The fluid should be replaced accord-
ing to the intervals specified in the Warranty
and Service Records Information booklet.
When driving under extremely hard conditions
(mountain driving, etc), it may be necessary to
replace the fluid more often. Consult a trained
and qualified Volvo service technician.
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.
Filling1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the fluid.
The level must be between the MIN and
MAX marks.
Power steering fluid
Check the level frequently. The fluid does not
require changing. The fluid level must be
between the MIN and MAX marks. For capaci-
ties and recommended fluid grade, see
page 277.
WARNING
If a problem should occur in the power
steering system or if the vehicle has no elec-
trical 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.
CAUTION
Keep the area around the power steering
fluid reservoir clean when checking.

Introduction
All bulb specifications are listed on page 228.
The following bulbs should only be replaced by
a trained and qualified Volvo service techni-
cian:
•Dome lighting
•Reading lights
•Glove compartment lighting
•Turn signals in the door mirror
•Approach lighting in the door mirror
•Brake/fog/taillights
•Rear side parking lights
•Active Bending Lights and LED bulbs
NOTE
For information regarding any other bulbs
not mentioned in this section, please con-
tact your Volvo retailer or a trained and
authorized Volvo service technician.
WARNING
•Active Bending Lights* – due to the high
voltage used by these headlights, these
bulbs should only be replaced by a
trained and qualified Volvo service tech-
nician.
•Turn off the lights and remove the
remote key from the ignition before
changing any bulbs.
Headlight housing
WARNING
•The engine should not be running when
changing bulbs.
•When changing in the headlight hous-
ing, if the engine has been running just
prior to replacing bulbs, please be
aware that components in the engine
compartment will be hot.
The entire headlight housing must be lifted out
when replacing all front bulbs (except for the
fog lights).
CAUTION
Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers
vaporize in the heat and will leave a deposit
on the reflector, which will damage it.

251 Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked Cmay have poor traction performance. The trac-
tion grade assigned to this tire is based on
braking (straight-ahead) traction tests and is
not a measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.
TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a minimum level of performance that
all passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
Snow chains, snow tires, studded tires
Snow chainsSnow chains can be used on your Volvo with
the following restrictions:
•Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
•All Wheel Drive models: Snow chains
should only be installed on the front
wheels.
