RETARDER (OPTIONAL)
Your vehicle is equipped with a retarder. It provides you with essential safety, cost
effectiveness, accurate and reliable braking.
Even at the lowest speeds, the retarder is very effective for common braking situations
(junctions, bends, turns,etc.) and for stops, virtually without using the service brakes.
Its highly flexible operation provides smooth braking and improves passenger comfort.
Your retarder will provide the necessary braking, whether at high road speeds or in
dense traffic. Its efficient usage will reduce fuel consumption and permit higher average
speeds in safety, whilst increasing brake and tyre service life.
Use the retarder in conjunction with the engine braking for an optimum use of the gear
ratios. This will allow you to achieve the speed best suited to changes in gradient and
to the road conditions as quickly as possible.
After the vehicle stabilises at the required speed, we recommend that you use the
retarder in position 2 to obtain maximum endurance efficiency.
Intermittently it may be useful to combine the use of the service brakes with the
operation of the retarder to adapt the vehicle’s speed to the road conditions (particularly
entering bends).
When tyre adhesion is poor, the retarder is particularly valuable : it allows you not only
to brake progressively, but may also be used for smooth startups on slippery ground.
Try position 1 and position 2 successively, checking the vehicle’s stability and tyre
adhesion.
ABS Interface
The retarder system is equipped with an electronic interface designed to work with your
vehicle’s Anti-Lock Braking System(ABS). During an ABS event (an ABS event is
defined as any wheel lock-up) the retarder will automatically turn off, allowing the ABS
to control the brakes without interference from retarder. After the ABS event, the
retarder will reactivate progressively to assure proper braking.
NOTE:
If the vehicle’s ABS warning light remains on, the retarder will not operate. When the
ABS warning light is on, there is a problem with the ABS. The ABS must be serviced
before the retarder will operate.
Important Points to Remember
•
The retarder operates by normally applying the brake pedal. You will notice that
less pedal travel is needed to obtain sufficient braking.
