DESCRIPTION AND OPERATION
ANTI-LOCK BRAKE SYSTEM - OPERATION
Warning lights
Brake fluid pressure/level and parking brake
warning lamp - (red)
The warning lamp situated in instrument binnacle
indicates insufficient pressure in system and/or low
fluid level and/or park brake applied. The warning
lamp will illuminate, for 3 seconds when ignition is
switched ON as part of initial bulb check, and
continuously when parking brake is applied.
If the pressure in hydraulic system is lower than the
cut-in pressure for the warning lamp, the lamp will
illuminate. When the lamp is on hydraulic pump will be
heard running.
NOTE: If the lamp remains illuminated
after the bulb check AND releasing the
park brake, DO NOT drive the vehicle until
the lamp extinguishes.
WARNING: IF THE LAMP ILLUMINATES
WHILE THE VEHICLE IS IN MOTION,
INVESTIGATE FAULT IMMEDIATELY.
BRAKING WILL BE AVAILABLE AFTER LOSS OF
PRESSURE, BUT GREATER FORCE AND TRAVEL
WILL BE REQUIRED AT THE PEDAL TO SLOW
THE VEHICLE.
ABS warning lamp - (yellow)
WARNING: Power assisted braking is not
available if ignition is switched off. An
increase in effort at brake pedal will be
required to apply brakes.
The ABS warning lamp situated in instrument binnacle
indicates a failure in ABS system.
The warning lamp will illuminate for 1 second when
ignition is switched ON, it will briefly extinguish and
will illuminate again. This indicates that the system
self monitoring check was successful, and system
performs correctly.
If it does not extinguish and illuminate again a system
fault has occurred.
The warning lamp will extinguish when vehicle speed
exceeds 7 km/h (5 mph).
If lamp remains on or subsequently illuminates with
ignition ON a fault in ABS system is indicated. The
self monitoring procedure is repeated frequently while
ignition is ON. If a fault is detected during self
monitoring, the lamp will illuminate indicating that one
or more wheels are not under ABS control.
WARNING: Reduced ABS control is
possible with ABS warning lamp
illuminated depending on severity and
type of fault. If both ABS and brake failure warning
lamps are illuminated, loss of system pressure or
hydraulic pump failure is indicated.
STOP VEHICLE AND IMMEDIATELY INVESTIGATE
THE FAULT.
Traction control warning lamp - (amber)
The Traction Control warning lamp situated in
instrument pack informs the driver that traction control
is active. The warning lamp will illuminate when the
ignition is switched ON, and the ABS and ETC
systems have completed their self checks, the ’TC’
lamp will illuminate for 3 seconds. This indicates that
the ETC system is operative, and also performs the
bulb check.
When traction control is active the lamp will illuminate
for a minimum of 2 seconds, a single audible chime
will sound and the message centre will display
’TRACTION’. The message and lamp will be
extinguished when ETC has stopped working.
On later models, the ’TRACTION’ message is not
displayed in the message centre. The driver is
informed of ETC operation by the ’TC’ warning lamp
and the single audible chime.
If a fault disables TC, the TC lamp will illuminate and
the message ’TRACTION FAILURE’ will be displayed.
A single audible chime will sound on the first
occurrence of the message.
If the system is over used and there is a risk of
components overheating, the system will shut itself
down. The TC lamp will flash for 10 seconds
minimum, a single audible chime will sound and the
message ’TRACTION OVERHEAT’ will be displayed.
Traction control will be available after components
have cooled down.
NOTE: Traction control only operates
below 50 km/h (30 mph) on models up to
99MY and below 100 km/h (62.5 mph) on
models from 99MY.
