‘Mode’ button. 2. Add new Transmitters.
2.1 Press ‘Set’ for 5 seconds to enter level 2 programming .
2.2 Press ‘Mode’ to select ‘Transmitter Learn’ mode.
2.3 Press ‘Tyre’ to display possible tyre positions (filled rectangles represent currently programmed
transmitters).
2.4 Press ‘Tyre’ to scroll to the desired position. The chosen road wheel icon will flash.
2.5 Program a new transmitter by either:
2.6 Vigorously shaking the transmitter (bounce the road wheel on the ground) to promote a transmission.
2.7 Inflate or deflate the tyre by more than 3 psi (0.2 bar).
2.8 Press ‘Tyre’ to scroll to the next position. Repeat steps 4 and 5 as required to programme additional
transmitters.
2.9 Press ‘Set’ to save the new transmitter data and to exit ‘learn’ mode. If no error is found, the system will
return to ‘normal’ mode.
Level 3 Programming
Low Pressure Alert
1. Press ‘Set’ for 10 seconds to enter level 3 programming .
2. Press ‘Tyre’ button to scroll to the desired axle.
3. Press ‘Mode’ to view the current low pressure alert value.
4. Press ‘Tyre’ to increase the current value or press ‘Mode’ to the decrease current value.
5. Press ‘Set’ to save when the desired value is reached.
6. Repeat steps 2 to 5 until the Low Pressure Alert Level has been set for all road wheels.
7. Press ‘Set’ button to exit this mode.

Brake system (06.00)
Anti-lock Braking System (ABS) (06.09)
The anti-lock braking system (ABS) is a four-channel system
having independent inputs from all four-wheel speed
sensors.
The ABS module, monitors signals from the sensors to
calculate, brake slip and the acceleration / deceleration of
individual wheels. When the brake pedal is depressed, and
the ABS module detects incipient wheel lock-up from the
incoming signals, it triggers the re-circulation pump inside
the module’s hydraulic modulator, and the solenoid valves
for the wheel(s) concerned. Brake pressure, is then
modulated to increase / decrease or remain constant at the
wheel(s) concerned until whee l lock-up is eliminated. The
ABS provides self-diagnosis and any malfunction within the
system will be indicated to the dr iver by the illumination of
the brake warning light and ‘ABS FAULT’ displayed in the
message centre right. Should a fault develop within the ABS,
the brake system will operate conventionally and with the
same standard of performanc e as a vehicle not equipped
with ABS.
Dynamic Stability Control
Dynamic Stability Control (DSC ) is a closed-loop system
designed to enhance driving safety by improving vehicle
handling when the tyres are at the limits of their grip
capabilities. This is achieved through instantaneous,
electronically controlled, reduction of engine torque and
strategic application of the brakes at individual wheels.
By using the principle that by controlling the brakes
individually it is possible, to an extent, to steer the vehicle.
This principle can be used to enhance driving safety by
correcting the vehicle’s yaw moment (turning force), when
the vehicle fails to follow th e driver’s steering inputs.
Concept
Satisfactory handling is determined according to whether a
vehicle maintains a path, wh ich accurately reflects the
driver
