Operation
If overbraking causes wheel lockup on the rear drive axles while
retarding devices are in operation, the ABS will interrupt and
disable the retarder until the lockup situation has stopped.
If the ABS warning indicator is lit, consult your nearest
International truck service center for further assistance in
maintaining and repairing your ABS.
Antilock Driving Tips
Brake just the way you always have. Apply brakes as
normal to stop in time. The ABS monitors the brake application
electronically and automatically controls the brakes, much faster
than a driver could do by pumping the brake pedal.
Always remember that you are the most important factor
to safe operation of your vehicle.
Steer clear of traffic,
pedestrians, animals, or other obstacles while you are in an
emergency braking situation.
The antilock tractor and truck
brake system will allow you to steer the vehicle during braking
while it comes to a full stop. ABS is not an excuse to take
unnecessary risks.
Always drive carefully and stay a safe
distance away from the vehicle in front of you.
When driving with a single trailer, double, or triple: Brake
as necessary and watch your trailer(s) through your mirrors and
correct steering as necessary to keep in straight lines.
If only your tractor has ABS: Use your tractor’s ABS brakes.
Steer clear of obstacles and watch the trailer through your
mirrors to make sure it follows your tractor properly. Tractor
ABS will help prevent tractor jackknife, but will not prevent trailer
swing out.
