Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
The warning light will remain on until the tire pressure is
corrected. The proper tire pressures for your vehicle
are listed on the Tire and Loading Information label
located on the driver side center pillar (B pillar). See
Loading the Vehicle on page 5-19.
You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is
first started and then turn off as you drive. This may be
an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.Note:The Tire Pressure Monitor can alert you about
low tire pressure, but it does not replace normal monthly
tire maintenance. It is the driver’s responsibility to
maintain correct tire pressures.
SeeTire Pressure Monitor System on page 6-70and
Tire Pressure Monitor Operation on page 6-72.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and displays a DIC message when
it is necessary to change the engine oil and filter. The
oil life system should be reset to 100% only following an
oil change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN, with the engine off.
2. Fully press and release the accelerator pedal
three times within five seconds.
3. Turn the key to LOCK/OFF.
SeeEngine Oil Life System on page 6-18.

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).

Windshield Washer
The windshield wiper paddle is located on top of the
multifunction lever.
L(Washer Fluid):Push the paddle to spray washer
fluid on the windshield. The wipers will clear the window
and then either stop or return to the preset speed.
{WARNING:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking your
vision.
Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has StabiliTrak
®, and the system begins to
limit wheel spin, cruise control will automatically
disengage. SeeStabiliTrak
®System on page 5-5. When
road conditions allow the cruise control to be safely
used again, it can be turned back on.
4-6
Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brakes are applied, this shuts off the cruise
control. But it does not need to be reset.
Once the vehicle speed reaches about 25 mph
(40 km/h) or more, press the +RES button on the
steering wheel. The vehicle returns to the previously set
speed and stays there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
•Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
•To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
To reduce the vehicle speed while using cruise control:
•Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
•To slow down in very small amounts, press the
SET– button on the steering wheel briefly. Each
time this is done, the vehicle goes about 1 mph
(1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle will
slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. When the
brakes are applied the cruise control turns off.
4-8
Speedometer and Odometer
The speedometer shows the vehicle speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
This vehicle has a tamper resistant odometer. The
digital odometer will read 999,999 if it is turned back.
If the vehicle needs a new odometer installed, it must be
set to the mileage total of the old odometer. If that is
not possible, then it must be set at zero and a label must
be put on the driver door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer can show how far the vehicle has
been driven since the trip odometer was last set to zero.
Press the Trip/Fuel button on the Driver Information
Center (DIC) switch to display the trip odometer and the
regular odometer information.
SeeDIC Operation and Displays on page 4-37for more
information on resetting the trip odometer.
To display the odometer reading with the ignition off,
press the Trip/Fuel button on the Driver Information
Center (DIC) switch.
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light comes
on and stays on for
several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
sounds for several seconds to remind the front
passenger to buckle their safety belt. The passenger
safety belt light, located on the instrument panel, comes
on and stays on for several seconds and then flashes
for several more.
4-22
When the ignition is on, the brake system warning light
also comes on when the parking brake is set. See
Parking Brake on page 3-36for more information. The
light stays on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push, or
the pedal might go closer to the floor. It could take
longer to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 5-26.
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock
brakes. If the regular brake system warning light is also
on, the vehicle does not have antilock brakes and
there is a problem with the regular brakes. SeeBrake
System Warning Light on page 4-27.
