the vehicle’s exhaust system, refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.
Idle-Up Feature
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional cab
heat, however, excessive idling may still cause the exhaust
aftertreatment system to not properly regenerate. Extended
periods of idle time should be avoided.
The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehicle’s
interior.
1. With the transmission in PARK, the parking brake
applied, and the engine running, push the speed control
switch to the ON position, then push the SET switch.
2. The engine RPM will go up to 1100 RPM. To increase the
RPM, push and hold the ACCEL/RESUME switch and
the idle speed will increase to approximately 1500 RPM.
To decrease the RPM, push and hold the DECEL switch
and the idle speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL
switch, push the ON/OFF switch, or press the brake pedal.
Noise
Diesel engines can create noises that may seem as a concern.
The nature of a diesel engine is compression ignition where
compressed air and fuel are mixed and ignited. Weather,
Barometric Pressure, Altitude and Temperature will affect how
fuel is ignited in the engine. Engine’s will sound different from
day to day or previous model years. Clicking, ticking, or light
knocking is normal and will change from day to day, as the
engine breaks in, and can vary with changes in ambient
temperature, this is normal. Diesel equipped vehicles also
have an exhaust aftertreatment system to reduce emissions
utilizing a DPF and a Selective Reduction Catalyst (SCR). The
SCR reduces Nox using the Diesel Exhaust Fluid (DEF)
system. DEF is injected directly into the SCR through an
dosing module. This process will create a clicking sound and
at times, will make noise even with the vehicle shut off. This
is normal as the DEF dosing module is purging DEF. Fuel
pump noise may increase during low speed/light load condi-
tions when ambient temperature is above 100°F (38°C), and
when fuel tank level is below 10%. This is a normal condition
of the fuel system and controls strategy. If at any time the
check engine light is on, please visit an authorized dealer.
