Fast Idle System
Fast Idle System with Switch
If the vehicle has this feature it is available only with
cruise control. The manual fast idle switch is operated
using the cruise control buttons located on the left
hand side of the steering wheel.
This system can be used to increase engine idle speed
whenever the following conditions are met:
•The park brake is set.
•The brake pedal is not pressed.
•The vehicle must not be moving and the accelerator
must not be pressed.
To control the fast idle:
•To Enable the Fast idle, press and release the
Cruise Control On/Off button and ensure that
the LED is lit.
•For the preset Fast Idle, press and release the
cruise set switch. This will set the preset fast
idle speed.
•For the variable fast idle, press and hold the
accelerator at the desired RPM, then press
and release the cruise control cruise set switch to
set the desired idle speed.When the fast idle is active the Driver Information
Center (DIC) will display “FAST IDLE ON.”
One of the following actions will turn off the fast idle:
•Pressing the brake.
•Selecting the Cancel button.
•Releasing the Parking Brake.
•The transmission shifter is moved out of P (Park) or
N (Neutral).
•Selecting the cruise control on/off button when it
was previously on.
Engine Coolant Heater
If the vehicle has the DURAMAX Diesel engine, see the
DURAMAX Diesel manual for more information.
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. An internal
thermostat in the plug-end of the cord may exist which
will prevent engine coolant heater operation at
temperatures above 0°F (−18°C).

To use this feature, do the following:
1. Move the shift lever to M (Manual Mode).
2. Press the plus/minus buttons, located on the
steering column shift lever, to select the desired
range of gears for current driving conditions.
When M (Manual Mode) is selected a number displays
in the DIC next to the M indicating the current gear.
This number is the highest gear that can be used.
However, the vehicle can automatically shift to lower
gears as it adjusts to driving conditions. This means that
all gears below that number are available. When
5 (Fifth) is selected, 1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle, but 6 (Sixth)
cannot be used until the plus/minus button located on
the steering column lever is used to change to the gear.
Grade Braking is not available when Range Selection
Mode is active. SeeTow/Haul Mode on page 3-34.While using Range Selection Mode, cruise control and
the Tow/Haul mode can be used.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on a
hill, use the brakes to hold the vehicle in place.
Low Traction Mode
Low Traction Mode can assist in vehicle acceleration
when road conditions are slippery. While the vehicle is at
a stop, select the second gear range using Range
Selection Mode. This will limit torque to the wheels after
it detects wheel slip, preventing the tires from spinning.

An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
The gage first indicates empty before the vehicle is out
of fuel, and the fuel tank should be refueled soon.
Listed are four situations customers might experience
with the fuel gage. None of these indicate a problem with
the fuel gage:
•At the gas station, the fuel pump shuts off before
the gage reads full.
•It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank’s
capacity to fill the tank.
•The gage moves a little while turning a corner or
speeding up.
•The gage does not go back to empty when the
ignition is turned off.
If the vehicle has the DURAMAX Diesel engine, see the
DURAMAX Diesel manual for more information.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located at
the bottom of the instrument panel cluster. The DIC
buttons are located on the instrument panel, next to the
instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected.
If your vehicle has these features, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. The compass
direction appears on the top right corner of the DIC
display. The outside air temperature automatically
appears in the bottom right corner of the DIC display.
If there is a problem with the system that controls
the temperature display, the numbers will be replaced
with dashes. If this occurs, have the vehicle serviced by
your dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 4-52for
more information.
