Standard air brakes (cam) are equipped
with automatic brake adjusters. Automatic
adjustment occurs during brake
applications. Inspect brakes for proper
adjustment at the specified intervals. See
Scheduled Maintenance (page 320).
Emergency Air Brake
WARNING
Do not continue to operate the
vehicle with a failure of one of the
brake systems. Take the vehicle to
your dealer for service immediately.
All vehicles are equipped with a dual brake
system. In the unlikely event of a failure of
one system, the second system functions
for emergency stopping. The brake pedal
controls all these systems in the same
manner as for normal stops.
EXHAUST BRAKE
WARNINGS
Do not use tow/haul when the road
surface is slippery. Failure to follow
this instruction could result in the
loss of control of your vehicle.

WARNINGS
Do not use diesel engine exhaust
braking when the road surface is
slippery. Failure to follow this
instruction could result in the loss of
control of your vehicle.
Note: Installing an exhaust or auxiliary
brake does not necessarily protect the
engine from exceeding the maximum
governed speed. Use the primary brakes to
make sure the engine never exceeds the
maximum governed speed under any
circumstance.
Note: Before starting the engine, make sure
that the exhaust brake is off. Do not switch
the exhaust brake on until the engine has
reached normal operating temperature.
Note: Maximum exhaust brake
performance relates to the type of
transmission your vehicle has.
Note: Engine speed has a major influence
on limiting performance. When engine
speed stays at the maximum allowable
level, the exhaust brake operates at peak
performance.
Note: Exhaust brakes operate effectively
with automatic transmissions. However,
performance varies with engine speed and
the gear selected by the transmission.
An exhaust brake is an auxiliary braking
system that assists, but does not replace,
the primary brake system. It helps control
vehicle speed. It is not a vehicle-stopping
device.
Use the button on the instrument panel, in
combination with the accelerator and
clutch pedals, to maximize the use of the
exhaust brake in the following conditions:
•
Off-highway driving.
•
Mountain driving.
•
Heavy traffic.
•
High-speed highway driving.
