155 Brake circuit malfunction
The brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle 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 – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a brake system message is
shown in the information display, DO NOT
DRIVE. Have the vehicle towed to a Volvo
retailer and have the brake system inspec-
ted.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple 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 occa-
sionally 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
when towing a trailer. 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)
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 auto-
matically modulated in order to help prevent
lockup that 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 approxi-
mately 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.

For optimal ABS braking effect:1. Press down on the brake pedal with full
force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel
and keep the brake pedal depressed.
Electronic Brake Force Distribution
(EBD)
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 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.
If the warning lamp lights up there is a mal-
function of the ABS system (the standard brak-
ing system will still function) and the vehicle
should be driven cautiously to a trained and
qualified Volvo service technician for inspec-
tion.
WARNING
If the BRAKES and ABS warning symbols
light at the same time, there may be a prob-
lem in the brake system. If the brake fluid
level is normal in these circumstances, drive
carefully to a trained and qualified Volvo
service technician to have the brake system
checked.
Emergency Brake Assistance – EBAEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.
NOTE
•When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

160
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 161 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
•Sling-type equipment applied at the front
will damage radiator and air conditioning
lines.
•It is equally important not to use sling-type
equipment at the rear or apply lifting equip-
ment inside the rear wheels; serious dam-
age to the rear axle may result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the vehicle on the flat bed. Con-
sult the tow truck operator.
WARNING
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but con-
siderably higher pressure will be
required on the brake pedal and greater
steering effort must be exerted.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.

General information
•Volvo recommends the use of Volvo trailer
hitches that are specially designed for the
vehicle.
CAUTION
Models equipped with the B5244S7 engine
(engine code 39, which is the 6th and
7th digits from the left in your vehicle's VIN
number, see page 268 for the location of
the VIN plate), may not be used to tow trail-
ers or vehicles of any kind. This could cause
damage to the vehicle's emission control
systems.
Maximum trailer weights recommended by
Volvo are:
•Trailers without brakes: 1,540 lbs
(700 kg).
•Trailers with brakes: 2,000 lbs (900 kg)
Observe the legal requirements of the
state/province in which the vehicles are
registered.
•The maximum recommended hitch
tongue load is 165 lbs (75 kg).
•All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•Increase tire pressure to recommended
full. See the chapter "Wheels and tires."
•When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•Maximum speed when towing a trailer:
50 mph (80 km/h).
•Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watched
when driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•If the automatic transmission begins to
overheat, a message will be displayed in
the information display.
•Avoid overload and other abusive opera-
tion.
•Hauling a trailer affects handling, durabil-
ity, and economy.
•It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•Do not connect the trailer's brake system
directly to the vehicle's brake system.
•More frequent vehicle maintenance is
required.
•Remove the ball and drawbar assembly
when the hitch is not being used.
•Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•Trailer hitches attaching to the vehicle's
rear axle must not be used.
•Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest trained
and qualified Volvo service technician
for correct installation.
•When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

Upholstery care
FabricClean 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. Consult your Volvo retailer.
Interior plastic componentsCleaning interior plastic components should
be done with a cleaning agent specially
designed for this purpose. Consult your Volvo
retailer.
Alcantera™ suede-like materialSuede-like upholstery can be cleaned with a
soft cloth and mild soap solution.
Leather careVolvo's leather upholstery is manufactured
with a protectant to repel soiling. Over time,
sunlight, grease and dirt can break down the
protection. Staining, cracking, scuffing, and
fading can result.
Volvo offers an easy-to-use, non-greasy
leather care kit formulated to clean and beau-
tify your vehicle's leather, and to renew the
protective qualities of its finish. The cleaner
removes dirt and oil buildup. The light cream
protectant restores a barrier against soil and
sunlight.Volvo also offers a special leather softener that
should be applied after the cleaner and pro-
tectant. It leaves leather soft and smooth, and
reduces friction between leather and other fin-
ishes in the vehicle.
Volvo recommends cleaning, protecting and
conditioning your vehicle's leather two to four
times a year. Ask your Volvo retailer about
Leather Care Kit 951 0251 and Leather Soft-
ener 943 7429.
Cleaning leather upholstery1. Pour leather cleaner on a damp sponge
and squeeze it until the cleaner foams.
2. Apply the foam to the stain by moving the
sponge with circular movements.
3. Dampen the stain thoroughly with the
sponge. Let the sponge absorb the stain,
do not rub.
4. Dry the stain with soft paper towels or a
towel, and allow the leather to dry com-
pletely.
Protecting leather upholstery1. Put a small amount of protectant cream on
a cloth and apply a thin coating of cream
to the upholstery with light circular move-
ments.
2. Allow the leather to dry for 20 minutes.This will help the leather resist staining and
protect against sunlight's harmful UV rays.
CAUTION
•Under no circumstances should gaso-
line, naphtha or similar cleaning agents
be used on the plastic or the leather
since these can cause damage.
•Take extra care when removing stains
such as ink or lipstick since the coloring
can spread.
•Use solvents sparingly. Too much sol-
vent can damage the seat padding.
•Start from the outside of the stain and
work toward the center.
•Sharp objects (e.g. pencils or pens in a
pocket) or Velcro fasteners on clothing
may damage the textile upholstery.
•Clothing that is not colorfast, such as
new jeans or suede garments, may stain
the upholstery.
