Anti-Lock Braking System (Abs U) - Vauxhall 2009 Tigra Owner's Manual

120 Driving and Operation
Anti-lock Braking System (ABS
ABS prevents the wheels from locking.
ABS starts to regulate brake pressure as
soon as a wheel shows a tendency to lock.
The vehicle remains steerable, even during
hard braking.
ABS control is made apparent through a
pulse in the brake pedal and the noise of
the regulation process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the
pedal is pulsating. Do not reduce the
pressure on the pedal.

Control indicator u for ABS
It comes on for a few seconds after the
ignition is turned on. The system is ready
for operation when the control indicator
goes out.
If the control indicator does not go out
after a few seconds, or if it illuminates while
driving, there is a fault in the ABS. The
brake system remains operational without
ABS regulation.
Self-check
When the engine is started and the vehicle
starts off, the system performs a self-check,
which may be audible.
Fault
9 Warning
If there is a fault in the ABS, the wheels
may be liable to lock due to braking that
is heavier than normal. The advantages
of ABS are no longer available. During
hard braking, the vehicle can no longer
be steered and may swerve.
Have the cause of the fault eliminated by a
workshop. The self-diagnosis integrated
into the system allows rapid fault
identification.
