Exhaust Brake Switch
Once the switch is in the ON position and the vehicle is
moving faster than 5 mph (8 km/h); the exhaust brake
will automatically operate when the driver removes
pressure from the accelerator pedal. Exhaust braking is
most effective when the engine RPM is higher. The
automatic transmission has been programmed to down-
shift more aggressively when the exhaust brake is en-
abled to increase brake performance.
CAUTION!
Use of aftermarket exhaust brakes is not recom-
mended and could lead to engine damage
WARNING!
Do not use the exhaust brake feature when driving in
icy or slippery conditions as the increased engine
braking can cause the rear wheels to slide and the
vehicle to swing around with the possible loss of
vehicle control, which may cause an accident possi-
bly resulting in personal injury or death.
NOTE: For optimum braking power it is recommended
to use the exhaust brake while in TOW/HAUL mode.
