STARTING AND DRIVING
451
Symbol Specification
Constant glow for 2 seconds
when the engine is started: Auto-
matic function check.
Constant glow for more than 2
seconds: Fault in the ABS sys-
tem. The car's normal brake sys-
tem is still working, but without
the ABS function.
If the message Brake pedal
Characteristics changed Serv-
ice required
is shown, the sys-
tem for "Brake-by-wire" is disen-
gaged. A higher pedal pressure is
required to produce braking
effect.
WARNING
If both the warning lamps for brake fault
and ABS fault illuminate at the same time,
a fault has occurred in the brake system.
•
If the level in the brake fluid reservoir is
normal at this stage, drive carefully to
the nearest workshop and have the
brake system checked - an authorised
Volvo workshop is recommended.
•
If the brake fluid is below the MIN level
in the brake fluid reservoir, do not drive
further before topping up the brake
fluid. The reason for the loss of brake
fluid must be investigated.

Brake assistance
The brake assist system (BAS
3
) helps to
increase brake force during braking, and can
thereby shorten the braking distance.
The system detects the way in which the
driver brakes and increases brake force where
necessary. The brake force can be boosted up
to the level when the ABS system is engaged.
The function is suspended when the pressure
on the brake pedal decreases.
