Diesel Engine Exhaust Brake - Chevrolet 2007 Kodiak Owner's Manual

Diesel Engine Exhaust Brake

If your vehicle has a Isuzu 6H or Caterpillar
Diesel Engine, it may have an exhaust brake,
which is located in the exhaust system.
If your vehicle has a 6.6L DURAMAX
Diesel Engine, it may have an exhaust brake,
which is controlled through the turbocharger.
The exhaust brake for both engines operates
the same.
Push the bottom of the switch to turn the exhaust
brake on. When you push the top of the switch,
the exhaust brake will turn off.
There is an indicator light on the instrument panel
similar to the symbol on the switch, that will come
on when the exhaust brake is active. See Exhaust
Brake Indicator Light on page 178 for more
information.

The exhaust brake
switch is located in the
instrument panel
switchbank.
When using the exhaust brake, the proper gear
range selection is important. The exhaust brake will
be most effective if the gear range selected is the
lowest possible range that does not allow the
engine rpm to go more than 200 rpm above rated
(full load) rpm. If you have a Caterpillar
Engine, do not exceed 2900 rpm. If you have a
Isuzu 6H Diesel engine, do not exceed 2550 rpm.
If you have a DURAMAX
not exceed 3600 rpm.
If your vehicle has an Allison
1000/2200/2300/2500 series automatic
transmission and press this button, the
transmission will downshift to a factory default
setting of third gear. To change the default setting,
or for more information on factory default
settings, contact your dealer for assistance.
The accelerator and clutch pedals must be
released in order for the exhaust brake to engage.
The exhaust brake will automatically shut off
when the anti-lock brake system is active.
If your vehicle has a Caterpillar
®
a DURAMAX 6600 Diesel Engine, the exhaust
brake will become active in cruise control
when you exceed the set speed by 3 to 5 mph.
