Brake system
06``153 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 runningThe 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, the brake
pedal must be pressed approximately five
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 roll-
ing. The brake pedal feels harder than usual.Water on brake discs and brake pads
affects brakingDriving 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 systemThe 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.

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
G020333
Brake fluid reservoirThe brake fluid should always be between the
MIN and MAX marks on the side of the reser-
voir. 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 your
Volvo retailer. Always entrust brake fluid
changing to a trained and qualified Volvo serv-
ice technician.
Power steering fluidThe fluid level is checked at each service inter-
val.
Fluid type: Volvo power steering fluid or equiv-
alent.
Replace: No fluid change required.
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.
