2004 VOLVO S60 brake

Brake system
BRAKE Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinders and two separate brake circuits. If a
problem should occur in one of these circuits, it is still possible to stop the car with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will
be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal Ð do not pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed
in the text window: DO NOT DRIVE. Have the car towed to a Volvo retailer and have the brake system inspected.
NOTE: When the car is at a standstill and the engine is idling, e.g. at a traffic light and the brake pedal is depressed,
the pedal may go down slightly. This is a normal function of the power-assisted brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately four times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas or towing. Vehicle speed is usually
slower, which means that the cooling of the brakes is less efficient than when driving on level roads. To reduce the
strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that, if you are
towing a trailer, the brakes will be subjected to a greater than normal load.

Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however

function) and the vehicle should be driven cautiously to a Volvo retailer for inspection. The Anti-lock Braking System
(ABS) helps to improve vehicle control (stopping and steering) during severe braking conditions by limiting brake
lockup. When the system "senses" impending lockup, braking pressure is automatically modulated in order to help
prevent lockup, which could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the
ABS control module. This is normal.
To obtain optimal effect from the ABS system, constant pressure should be kept on the brake pedal, keep constant
pressure on the brake pedal. Do not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. Please be aware
that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not
shorten stopping distances on slippery surfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity. The brake pedal will pulsate during braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake system.
Stop the car in a suitable place and switch off the engine.
Restart the engine.
If both warning lights go off, no further action is required.
If both lights are still on after the engine has been restarted, switch off the engine again and check the brake fluid
level (see page 124
for the location of the brake fluid reservoir).
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake failure - Service urgent" message is displayed
in the text window: DO NOT DRIVE. Have the car towed to a Volvo retailer and have the brake system inspected.
If the brake fluid level is above the MIN mark, drive carefully to an authorized Volvo retailer and have the brake
system inspected.

New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year will be indicated with 4 digits
(e.g. 1502 means that the tire illustrated was manufactured during week 15 of 2002).
Improving tire economy:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
If tires are rotated, they must be kept on the same side of the car so that they revolve in the same direction as before
rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. In cold weather, it takes longer for the tire to warm up and consequently longer for the flat spot to
disappear.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
R-models only: 16" wheels may not be used. Consult your Volvo retailer about the types of wheels that may be
mounted on R-models.
pg. 109 Wheels and tires
Snow chains
Snow 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.
Special snow chains must be mounted on 195/65 R15. For tires of other dimensions, consult your Volvo retailer.
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. Only chains adapted for AWD
models should be used.
NOTE: Consult your Volvo retailer for additional snow chain information
CAUTION:
Check local regulations regarding the use of snow chains before installing
Always follow the chain manufacturer's installation instructions carefully. Install chains as tightly as possible and
retighten periodically.
Never exceed the chain manufacturer's specified maximum speed limit. (Under no circumstances should you exceed 31
ProCarManuals.com

Tires with less than 1/16" (1.6 mm) tread have a very poor grip in rain or snow.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.

Changing wheels
Insert flat end of lug wrench and turn/pull straight out
Changing wheels
The spare wheel is located under the carpet on the trunk floor. The jack and crank are secured in the wheel recess.
There are two jack attachment points on each side of the car (see illustration on next page). To change a wheel:
Engage the parking brake.
Put the gear selector in (P)ark (automatic transmission) or reverse (manual transmission).
Loosen the wheel bolts
Remove the wheel cap (where applicable) using the lug wrench in the tool bag.
With the car still on the ground, use the lug wrench to loosen the wheel bolts 1/2 - 1 turn. Turn the bolts
counterclockwise to loosen.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.

when replacing a wheel. For any other job, use stands to support the side of the car being worked on.
Apply the parking brake and put the gear selector in the (P)ark position (or reverse on manual transmissions).
Block the wheels standing on the ground, use rigid wooden blocks or large stones. The jack should be kept well-
greased.

Uniform Tire Quality Grading
ALL PASSENGER CAR TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 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 significantly from the norm due to variation in driving habits,
service practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
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.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions 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 corresponds to a minimum level of performance that all
passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible
tire failure.

Bumpers: Wash the bumpers with the same cleaning agent used on the rest of the car. Never clean the bumpers with
gasoline or paint thinner. Difficult spots can be removed with denatured alcohol. To avoid scratches, do not dry the
bumpers with paper.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills.
Automatic car wash
An automatic car wash is a simple and quick way of washing the car. Bear in mind, however, that an automatic car
wash can never replace a proper handwashing. During the first months of the car's life - while the paint is still curing -
we recommend that you handwash the car.
WARNING!
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
pg. 117 Car care
Automatic washing - simple and quick
We do NOT recommend washing your car in an automatic wash during the first six months (because the paint will
not have hardened sufficiently).
An automatic wash is a simple and quick way to clean your car, but it is worth remembering that it may not be as
thorough as when you yourself go over the car with sponge and water. Keeping the underbody clean is most important,
especially in the winter. Some automatic washers do not have facilities for washing the underbody.
Before driving into an automatic car wash, make sure that side view mirrors, auxiliary lamps, etc, are secure, and
that any antenna( s) are retracted or removed. Otherwise there is risk of the machine dislodging them.
Polishing and Waxing
Normally, polishing is not required during the first year after delivery, however, waxing may be beneficial.
Before applying polish or wax the car must be washed and dried. Tar spots can be removed with kerosene or tar
remover. Difficult spots may require a fine rubbing compound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax.
Waxing alone does not substitute for polishing a dull surface.
A wide range of polymer-based car waxes can be purchased today. These waxes are easy to use and produce a
long-lasting, high-gloss finish that protects the bodywork against oxidation, road dirt and fading.
Do not polish or wax your car in direct sunlight (the surface of the car should not be warmer than 113° F (45° C).
Cleaning the upholstery
The fabric can be cleaned with soapy water or a detergent. For more difficult spots caused by oil, ice cream, shoe
polish, grease, etc., use a clothing/fabric stain remover.
The plastic in the upholstery can be cleaned with a soft cloth and mild soap solution.
Leather upholstery/suede-like upholstery (alcanteraTM) can be cleaned with a soft cloth and mild soap solution. For
more difficult spots, Volvo offers a leather care kit.
Under no circumstances should gasoline, naphtha or similar cleaning agents be used on the plastic or the leather
since these can cause damage.
Cleaning the seat belts
Clean only with lukewarm water and a mild soap solution.

The cooling system must always be kept filled to the correct level. If it is not kept filled, there can be high local
temperatures in the engine which could result in damage. Different types of antifreeze/coolant may not be mixed.
Check coolant regularly!
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the car cools.
If it is necessary to top up the coolant when the engine is warm, unscrew the expansion tank cap slowly so that the
overpressure dissipates.
