DRIVING YOUR MOTOR HOME

JACOBS

EXTARDER™ ENGINE

EXHAUST BRAKING SYSTEM

To Use the Exhaust Brake: The exhaust brake

activation switch is located on the lower left side

of the dash. Press and release the ON side of the

switch to activate the exhaust brake system. The

exhaust brake will operate whenever you let up

on the throttle pedal while the switch is ON.

Press and release the OFF side of the switch to

deactivate the exhaust brake system and return to

chassis brakes alone.

How It Works: The Jacobs

Extarder

is an

engine compression retarder that generates

“braking” power by controlled restriction of the

engine’s exhaust gas flow.

When the exhaust brake is activated, a valve

closes off the engine’s exhaust causing the ex-

haust 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 mountain-

ous or hilly roads. It also provides “braking” on

level or near-level roads.

For More Information: See your Jacobs

Extarder

user guide in the Owner’s InfoCase

for complete operating instructions and precau-

tions.
