PART 7: STARTING & OPERATING THE VEHICLE ANTI-LOCK BRAKING SYSTEM OPERATING INFORMATION
(R10/06) Y53-6007 – 89 –
WARNING!
• The brake system is a critical vehicle safety
system. For the safety of you and others
around you, have the vehicle submitted for
periodic preventive maintenance checks as
well as having any suspected problems
immediately checked by an Authorized Ser
-
vice Center. Failure to properly maintain
your brake system can lead to serious
injury accidents.
• Do not drive through water deep enough to
wet brake components, as it may cause the
brakes to work less efficiently than normal.
The vehicle's stopping distance may be
longer than expected, and the vehicle may
pull to the left or right when brakes are
applied, which could contribute to an acci
-
dent.
• Do not rely on an anti-lock brake system
that is functioning improperly. You could
lose control of the vehicle resulting in a
severe accident and personal injury. If any
ABS lamp goes on while you are driving or
stays on after the self-check, that anti-lock
system might not be working. That ABS
may not function in an emergency. You will
still have conventional brakes, but not anti-
lock brakes. If any warning lamp indicates a
problem, have that ABS checked.
ABS Warning Lamps
Truck/Tractor ABS Warning Lamp
A truck/tractor ABS warning lamp illuminates when the
ignition switch is first turned on and will remain on until the
system self-test has been completed successfully. Nor
-
mally, this ABS lamp will remain on until a speed of no
more than 9 mph has been reached and the speed sen
-
sors have been checked for correct output. The lamp
should remain off after this point unless a failure in the
system is detected.
CAUTION: If the truck/tractor ABS warning
lamp does not illuminate when the ignition is
first turned on, there is a problem with the
bulb or wiring. The driver should have this
checked as soon as possible.
The truck/tractor ABS lamp is located in the warning lamp
cluster. (See illustration on
page 47.).
