120 OPERATION
Anti-Lock Brake System (ABS)
ABS Operation
When operating an ABS-equipped vehicle, the following guidelines should be used.
•
Apply the brakes as normal. If the anti-lock brake system begins to function, maintain
brake pressure. Do NOT release the brakes.
•
Avoid rapidly pumping the brakes. The anti-lock brake system automatically applies and
releases the brakes up to five times per second.
•
When towing a trailer, watch the trailer through the mirrors. Adjust brake application
as necessary to keep the combination in a straight line. Make sure the trailer follows
the tractor properly.
•
An amber trailer ABS lamp on the instrument panel will illuminate for several seconds at
start-up during an initial function check. When a trailer ABS fault occurs, the lamp will
remain illuminated until the fault is cleared. If there is a loss of communication between
the tractor and trailer, the lamp will blink three times. Refer to “Anti-Lock Brake System
(ABS)”, page 120 for more information.
