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.
The exhaust brake activation switch is located
on the driver sidewall panel.
Further Information
See your chassis manual in your InfoCase for
more instructions, information and precautions
on using this feature.
OVERDRIVE SWITCH
–Workhorse Chassis 20,700 GVWR and
greater only
The Overdrive Switch allows you to
deactivate the automatic overdrive feature of the
transmission when necessary.
When this switch is ON, the transmission will
automatically shift to the overdrive gear
whenever possible for greatest fuel economy.
Some driving situations, however, may
require the transmission to be temporarily
disabled from shifting into overdrive gear, such
as when towing a car or trailer, driving in rolling
hill country or driving into a strong headwind
where the transmission will repeatedly shift up
and down causing annoyance and reduced fuel
economy.
See your chassis manual for further
information on this switch.
HAZARD WARNING FLASHERS
The hazard warning flashers provide
additional safety when the vehicle must be
stopped on the side of the roadway and presents a
• To Activate - Press and release the ON side of
the switch. The exhaust brake will operate
whenever you let up on the throttle pedal while
the switch is ON.
• To De-activate - Press and release the OFF
side of the switch to return to chassis brakes
alone.
To Use the Exhaust Brake
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.
