ABS monitoring
The ABS control module monitors the
ABS electrical system from ignition switch
ON to ignition switch OFF. Any
malfunction will be indicated by the
anti-lock warning light coming on.
Should a fault develop in the ABS system,
the brake system will still operate
conventionally and with the same
standard of performance as vehicles not
equipped with ABS.
Caution: Consult a Jaguar Dealer
immediately if the warning light
come on while driving, a system
failure is indicated.
Advice on ABS braking
techniques
For optimum ABS performance the
instructions on braking techniques during
ABS operation should be followed:
1. Do not release brake pressure when
the pulsating effect is felt. Maintain a
constant pressure until the manoeuvre
is completed.
2. To familiarise yourself with the feel of
the brake pedal during ABS braking,
practise an emergency stop
procedure, always making sure it is
safe to do so. With the seat belts fitted
to all occupants, drive the vehicle at
32 km/h (20 mph) and brake sharply.
3. ABS enables the driver to steer around
obstacles during emergency braking.
However, the consequences of turning
sharply at high speed cannot be
overcome by the ABS.
4. Do not attempt to ‘pump’ the brakes
to avoid skidding as this can interfere
with the ABS operation. The ABS will
not allow the wheels to skid under
normal road conditions.
5. The ABS will tend to keep the vehicle
straight during braking. Because
braking distances may increase under
certain road conditions, it is necessary
to plan and make turning manoeuvres
as early as possible.
