hydraulic pressure. The driver should not attempt to emulate
this process by 'pumping' the brake pedal, as modulation in this
manner will treat all four wheels similarly, rather than individu-
ally as afforded by the ABS electronics.
An ABS tell tale lamp in the instrument panel is provided to
warn that the integral self diagnostic system has identified a
problem, and to indicate that the anti-lock function has been
turned off. See 'ABS tell tale lamp'.
WARNING
• The amber ABS tell tale in the instrument panel should light
for about 3 seconds following ignition switch on, and then
go out. If the lamp remains lit, or comes on whilst driving,
a fault in the anti-lock brake system is indicated. The base
brake system will continue to operate normally, but without
the anti-lock feature. Heavy braking, or braking on slippery
surfaces may cause one or more wheels to lock and result
in reduced steering response and possible loss of control.
The car may continue to be driven with appropriate care
and anticipation, but should be checked and repaired at the
earliest opportunity.
• The increased control that ABS provides should not induce
you to take more risks with your safety. ABS will not prevent
a skid caused by abrupt steering movements, or attempting
to corner too quickly.
• Always maintain a safe following distance from other vehi-
cles relative to the road surface and weather conditions.
• ABS does not avoid the risk of an accident due to inappro-
priate speed. The driver is at all times responsible for the
judgement of safe speed.
• The control unit of the ABS is set for standard wheel and tire
sizes. If non-standard wheels or tires are fitted, the control
unit may mis-interpret the speed of the car, because of the
variant data it receives from the wheel speed sensors. Fit-
ting non-approved wheels or tires could seriously affect the
performance of the ABS.
• Activation of the ABS will vary according to the level of grip
available at the tires. On dry surfaces, activation will occur
only with a high pedal pressure. On slippery surfaces, only
a low pedal pressure will be needed.
• On loose or uneven surfaces, such as gravel or snow, a car
with ABS may need a longer stopping distance. Allow a
greater following distance in these conditions.
