PARKING BRAKE
Freightliner
®
Chassis
Use the parking brake knob to apply the park
brake whenever the vehicle is parked.
Never try to drive the vehicle with the parking
brake applied. This can cause excessive wear on
the brakes and may damage the transmission.
NOTE: It is normal to hear an occasional burst
of air pressure from the rear of the
vehicle. This is an automatic moisture
purging feature of the air brake system.
See the Brakes section of your chassis
manual for instructions on periodic
draining of brake air tank.
EXHAUST RESTRICTION
BRAKING SYSTEM
Freightliner
®
Chassis
The Exhaust Brake generates additional
“braking” power by controlled restriction of the
engine’s exhaust gas flow.
How It Works
When the Exhaust Brake is activated, a valve
closes off the engine’s exhaust causing the
exhaust back pressure to increase, which causes
the vehicle to slow down.
The increased back pressure would normally
stop the engine except the forward momentum of
the vehicle keeps the drivetrain and the engine
turning.
This controlled back pressure helps to regulate
a vehicle’s downhill speed, such as on
mountainous or hilly roads. It also provides
“braking” on level or near-level roads.
To use the Exhaust Brake

See your chassis manual in your InfoCase for
more instructions, information, and precautions
on using this feature.

WARNING
Do not activate the engine exhaust
braking system while on icy or extremely
wet roads or in any other situation where
abrupt deceleration could cause skidding
or loss of vehicle control.
Exhaust Brake Switch
(Located on driver’s steering column on the
right hand stalk switch)
-Typical View
• To
activate exhaust brake automatically the
shifter remains perpendicular to the column, or
in the highest position.
• Operate the engine brakes manually by moving
the shifter stalk in a clockwise direction. the
setting are low, medium, and high engine
braking.
• When the engine brake is set to the auto position
with cruise control set, the engine braking is
controlled by the parameter settings for the
optional cruise control band switch.
