pg. 18 Brake system

Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinder\
s and two separate brake
circuits. If a problem should occur in one of these circuits, it is stil\
l possible to stop the car with the other
brake circuit.
If the brake pedal must be depressed farther than normal and requires gr\
eater 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 ch\
eck 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: DO NOT DRIVE.\
Tow the car 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 traf\
fic light and the brake pedal
is depressed, the pedal may go down slightly. This is normal and is caus\
ed by an built-in function in the
power 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 app\
roximately 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. Th\
e 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 c\
ause 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 weath\
er.
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 l\
ess 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 wil\
l be subjected to a greater than
normal load.
pg. 19 Anti-lock Brake System (ABS)


Anti-lock Brake System (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 Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
The system performs a self-diagnostic test when the engine is started an\
d 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.

06 4:32:55 PM

2004 VOLVO XC70
To obtain optimal effect from the ABS system, constant pressure should b\
e 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 w\
ill pulsate during braking.
Please be aware that ABS does not increase the absolute braking potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
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 duri\
ng 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.
l Stop the car in a suitable place and switch off the engine.
l Restart the engine.
l If both warning lights go off, no further action is required.
l If both lights are still on after the engine has been restarted, switch \
off the engine again and check the
brake fluid level (see
pages 139 and for the location of the brake fluid reservoir).
WARNING!
If the fluid level is below the MIN mark in the reservoir, DO NOT DRIVE.\
Have the car towed to an
authorized Volvo retailer and have the brake system inspected.

l If the brake fluid level is above the MIN mark, drive carefully to an au\
thorized Volvo retailer and
have the brake system inspected.

This light indicates that the rear fog light is on.

Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine,
transmission, electrical and emission systems. The CHECK ENGINE light wi\
ll light up if the computer
senses a condition that potentially may need correcting. When this happe\
ns, please have your car checked by
a Volvo retailer as soon as possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice\
a change in your car's
behavior. Even so, an uncorrected condition could hurt fuel economy, emi\
ssion cleanliness, and driveability.
Extended driving without correcting the cause could even damage other co\
mponents in your car.
Canadian models are equipped with this warning light:

NOTE: If the fuel filler cap is not closed tightly or if the engine is runni\
ng when the car is refueled, the
Malfunction Indicator Lamp may indicate a fault. However, your vehicle's\
performance will not be affected.
Use only Volvo original or approved fuel filler caps.
