Diesel Engine Exhaust Brake; Instrument Panel - Chevrolet Kodiak 2006 Owner's Manual

Diesel Engine Exhaust Brake

If your vehicle has a DURAMAX
diesel engine, it may have an exhaust brake, which
is located in the exhaust system.
If your vehicle has a 6.6L DURAMAX
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 3-41 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 diesel engine, do not exceed
2900 rpm. If you have a DURAMAX
engine, do not exceed 2550 rpm. If you have a
®
DURAMAX 6600 diesel engine, do not exceed
3600 rpm.
If your vehicle has an Allison
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
®
DURAMAX 6600 diesel engine, the exhaust brake will
become active in cruise control when you exceed
the set speed by 3 to 5 mph.
