Foot Brake - Anti-Lock Braking System; Foot Brake - Emergency Brake Lights And Automatic Hazard Warning Flashers - Volvo V40 Owner's Manual

STARTING AND DRIVING
||
WARNING
If and illuminate at the same
time, there may be a fault in the brake system.
If the level in the brake fluid reservoir is nor-
mal at this stage, drive carefully to the nearest
workshop and have the brake system checked
- an authorised Volvo workshop is recom-
mended.
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.

Foot brake - anti-lock braking
system
The anti-lock braking system, ABS (Anti-lock
Braking System), prevents the wheels from lock-
ing up during braking.
The function allows the steering ability to be
maintained, and it is easier to swerve to avoid a
hazard for example. Vibration may be felt in the
brake pedal when this is engaged and this is nor-
mal.
A short test of the ABS system is made automat-
ically after the engine has been started when the
driver releases the brake pedal. A further auto-
matic test of the ABS system may be made at
low speed. The test may be experienced as pul-
ses in the brake pedal.

Foot brake - emergency brake lights
and automatic hazard warning
flashers
Emergency brake lights are activated to alert
vehicles behind about heavy braking. The func-
tion means that the brake light flashes instead of
- as in normal braking - shining with a constant
glow.
Emergency brake lights are activated at speeds
above 50 km/h (31 mph) if the ABS system is
working and/or in the event of heavy braking.
After the car's speed has been slowed below
10 km/h (6 mph) the brake light returns from
flashing to the normal constant glow - while at
the same time the hazard warning flashers(p. 99)
are activated, and they flash until the driver accel-
erates the car to at least 20 km/h (12 mph) or
they are deactivated with their button.
