CAUTION!
Use of aftermarket exhaust brakes is not recommended 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 a collision
possibly resulting in personal injury or death.
IDLE-UP FEATURE (AUTOMATIC TRANSMISSION ONLY)
• The Idle-Up Feature uses the speed control switches to increase engine idle speed
and quickly warm the vehicle’s interior. This feature must be enabled by your
dealer. See your local dealer.
• With the transmission in PARK, the parking brake applied, and the engine
running, push the speed control ON/OFF switch on, then push the SET switch.
• The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the
RESUME/ACCEL switch and the idle speed will increase to approximately
1500 RPM. To decrease the RPM, push and hold the SET/DECEL switch and the
idle speed will decrease to approximately 1100 RPM.
• To cancel the Idle Up Feature, either push the CANCEL switch, push the ON/OFF
switch or push the brake pedal.
