08 Starting and driving
Foot brake
The foot brake is used to reduce the car's
speed while driving.
The car is equipped with two brake circuits. If
a brake circuit is damaged then the brake
pedal will engage deeper and a higher pres-
sure on the pedal is needed to produce the
normal braking effect.
The driver's brake pedal pressure is assisted
by a brake servo.
WARNING
The brake servo only works when the
engine is running.
If the foot brake is used when the engine is
switched off then the pedal will feel stiff and a
higher pedal pressure must be used to brake
the car.
In very hilly terrain or when driving with a
heavy load the brakes can be relieved by
using engine braking. Engine braking is most
efficiently used if the same gear is used
downhill as up.
For more general information on heavy loads
on the car, see Engine oil - adverse driving
conditions (p. 420).

Cleaning the brake discs
Coatings of dirt and water on the brake discs
may result in delayed brake function. With
300
wet road surfaces, prior to long-stay parking
and after the car has been washed, it is there-
fore advisable to carry out cleaning by brak-
ing gently for a short period while driving.
Maintenance
To keep the car as safe and reliable as possi-
ble, follow the Volvo service intervals as
specified in the Service and Warranty Book-
let.
IMPORTANT
The wear on the brake system's compo-
nents must be checked regularly.
Contact a workshop for information about
the procedure or engage a workshop to
carry out the inspection - an authorised
Volvo workshop is recommended.
Symbols and messages
Symbol
Specification
Constant glow – Check the
brake fluid level. If the level is
low, fill with brake fluid and
check for the cause of the
brake fluid loss.
Constant glow for 2 seconds
when the engine is started -
automatic function check.
WARNING
If
and
illuminate at the same
time, there may be a fault in the brake sys-
tem.
If the level in the brake fluid reservoir is
normal at this stage, drive carefully to the
nearest workshop and have the brake sys-
tem checked - an authorised Volvo work-
shop is recommended.
If the brake fluid is below the MIN level in
the brake fluid reservoir, do not drive fur-
ther before topping up the brake fluid.
The reason for the loss of brake fluid must
be investigated.
