EXHAUST BRAKE (IF EQUIPPED)
Note:
The exhaust brake is
intended to help control vehicle
speed; it is not a vehicle stopping
device.
An exhaust brake is an optional
auxiliary braking system that assists,
but does not replace, the primary
service brake system. An on-off
switch on the instrument panel, in
combination with the accelerator
and clutch pedal switches, allows the operator to make maximum use of
the exhaust brake in the following conditions:
•
off-highway driving
•
mountain driving
•
heavy traffic
•
high speed highway driving
