Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your 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, you can maintain a speed of
about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
When you apply your brakes, cruise control
is turned off.If your vehicle has an Allison
®automatic
transmission, see “Grade Braking and Cruise
Grade Braking (Allison Transmission
®) under
Tow/Haul Mode on page 144for an explanation of
how cruise control interacts with the range selection
mode, tow/haul and grade braking systems.
If your vehicle has the StabiliTrak
®™ system and
begins to limit wheel spin while you are using
cruise control, the cruise control will automatically
disengage. SeeStabiliTrak
®System on
page 381. When road conditions allow you to
safely use it again, you may turn the cruise
control back on.
The cruise control
buttons are located on
left side of the
steering wheel.

T(On/Off):This button can both activate and
turn off the system. The indicator light is on
when cruise control is on and turns off when cruise
control is off.
+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET−(Set/Coast):Press this button to set the
speed or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control without erasing the set speed from
memory.
Setting Cruise Control
Cruise control will not work if the parking brake
is set, or if the master cylinder brake uid level
is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set the cruise control at a desired
speed and then you apply the brake. This shuts off
the cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering
wheel. The vehicle will go back to the previous set
speed and stay there.
219

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 you reach your new
desired speed, then release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is
done, the vehicle will go 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
briey. Each time this is done, the vehicle will
go 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. Of
course, applying the brake turns off the cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the
steering wheel.

Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
The exterior lamps control has four positions:

Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 289.
As with any vehicle, you should turn on the regular
headlamp system when needed.
Puddle Lamps
Your vehicle may have puddle lamps, that come
on when it is dark outside to help you see the area
near the base of the front doors. The puddle
lamps will come on when a door is opened, or
when you press the unlock button on the Remote
Keyless Entry Transmitter. The lamps will time
out or turn off once the engine is started.
Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the button is located on the instrument panel
to the left of the steering column and below the

button. A light comes on in the instrument
panel cluster to let you know that the fog lamps
are on. Press the button again to turn the fog
lamps off.
When the fog lamps are turned on, the low-beam
headlamps automatically turn on.
The fog lamps turn off while you change to
high-beam headlamps. When the high-beam
headlamps go off, the fog lamps will come
on again.
Fog lamps should only be used in foggy conditions
since they could be distracting to oncoming
drivers in clear weather conditions.
Some localities have laws that require the
headlamps to be on along with the fog lamps.

Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 374. By taking a few moments to read this
manual and get familiar with your vehicle’s
audio system, you can use it with less effort, as
well as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone and adjusting the speakers. Then, when
driving conditions permit, you can tune to
your favorite stations using the presets and
steering wheel controls if the vehicle has them.{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. Here are some ways in which you can
help avoid distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
