CAUTION
If the ABS warning light does not illu-
minate
when the ignition is first turned
on, there is a problem with the bulb or
wiring. You should have this checked
as soon as possible.
WARNING
No indication will be given via the
dashboard
warning lights or buzzer if
tires of the wrong size are installed on
your vehicle. The Anti-Lock Brake Sys-
tem (ABS) is calibrated for the specific
tire revolutions per mile. Use of a tire
and/or wheel size different from that
originally installed on your vehicle may
cause the ABS system to not function
during a hard braking event. This
could cause an accident or serious
personal injury. Consult with your deal-
er before using a different tire and/or
wheel size than was originally installed
on your vehicle.
Automatic Traction Control
Your truck/tractor ABS is equipped with an
automatic traction control (A
TC) feature.
This feature is controlled by a switch on the
dash. Do not allow the traction control lamp
to remain on continuously for an extended
length of time. Extended continuous use of
the ATC can cause overheating of the drive
wheel brakes. Engine torque or vehicle
speed should be reduced to eliminate
wheel spin and prevent excessive
application of the ATC system. Except for
checking for proper illumination of the ABS
and traction control warning lamps when
first starting the vehicle, and for monitoring
these lamps while driving, no special
operating procedures are required. For
detailed system description, see literature
for your specific ABS that was provided
with your vehicle.
Emergency Braking
WARNING
Unless you have an anti-lock braking
system
(ABS), always avoid complete-
ly depressing the service brake pedal,
if possible, even during emergency
braking. Depressing the brake pedal
too aggressively can cause the wheels
to lock, which can lead to an uncon-
trolled skid and can result in an acci-
dent. Failure to comply may result in
property damage, personal injury, or
death.
For Non-ABS Vehicles:
T
o stop your vehicle in an emergency, vary
the service brake application pressure to
provide maximum braking force without
locking the wheels. Use engine
compression to assist the service brakes
by not depressing the clutch pedal until the
engine reaches idle speed.
Brake Warning Lamp
When the brake warning lamp comes on, it
indicates a malfunction in the brake
system. Possible malfunctions include loss
of hydraulic pressure from the power
