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 40 km/h (25 mph)
or more can be maintained without keeping your foot on
the accelerator. Cruise control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the cruise control
turns off.
For vehicles with an Allison
®or Hydra‐Matic 6‐speed
automatic transmission, see “Grade Braking and Cruise
Grade Braking (Allison Transmission) under Tow/Haul
Mode
on page 3‑34for an explanation of how cruise
control interacts with the Range Selection Mode,
tow/haul and grade braking systems.
For vehicles with the StabiliTrak
®system, if it begins to
limit wheel spin while the cruise control is being used,
the cruise control will automatically disengage. See
StabiliTrak
®Systemon page 5‑6. When road
conditions allow the cruise control to be safely used
again, it can be turned back on.

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, the vehicle slows
down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control works 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.
4-10

When going downhill, you might have to brake or shift

Exterior Lamps
The exterior lamps
control is located on the
instrument panel to the
left of the steering wheel.It controls the following systems:
.Headlamps
.Taillamps
.Parking Lamps
.License Plate Lamps
.Instrument Panel Lights
The exterior lamps control has four positions:
O(Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turning the headlamp
control to the off position again turns the automatic
headlamps or DRL back on.
For vehicles first sold in Canada, the off position only
works for vehicles that are shifted into the P (Park)
position.
AUTO (Automatic) : Automatically turns on the
headlamps at normal brightness, together with the
following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
4-11

;(Parking Lamps) : Turns on the parking lamps
together with the following:
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
2 (Headlamps) : Turns on the headlamps together with
the following lamps listed below.
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
When the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
Headlamps on Reminder
A reminder chime will sound when the headlamps or
parking lamps are manually turned on and the ignition is
off and a door is open. To disable the chime, turn the
light off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
The DRL system comes on when the following
conditions are met:
.The ignition is on.
.The exterior lamps control is in AUTO.
.The engine is running.
.The light sensor determines it is daytime.
When the DRL system is on, only the DRL lamps are
on. The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
When it begins to get dark, the automatic headlamp
system switches from DRL to the headlamps.
4-12

To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles first sold in Canada, the transmission
must be in the P (Park) position, before the DRL lamps
can be turned off.
Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system turns on the headlamps at the normal
brightness, along with the taillamps, sidemarker, parking
lamps, and the instrument panel lights. The radio lights
will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release it. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Do not cover
the sensor or the headlamps will come on whenever the
ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system is only affected when the light
sensor detects a change in lighting lasting longer than
the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. See
Instrument
Panel Brightness on page 4‑14.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). See DIC Vehicle
Customization (With DIC Buttons) on page 4‑66.
The regular headlamp system can be turned on when
needed.

Fog Lamps
For vehicles with fog lamps, the control is located next
to the exterior lamps control on the instrument panel to
the left of the steering column.
#(Fog Lamps):Press the button to turn the fog lamps
on or off. A indicator light comes on in the instrument
panel cluster. The ignition must be in the ON/RUN
position for the fog lamps to come on.
When the fog lamps are turned on, the headlamps
automatically turn on.
When the headlamps are changed to high-beam, the
fog lamps also go off. When the high-beam headlamps
go off, the fog lamps will come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel Brightness
D (Instrument Panel Brightness) : This feature
controls the brightness of the instrument panel lights
and is located next to the exterior lamp control.
Push the knob to extend out and then it can be turned. Turn the knob clockwise or counterclockwise to brighten
or dim the instrument panel lights. Turning the knob to
the farthest clockwise position turns on the dome lamps.
Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located on the
instrument panel to the left of the steering column,
clockwise to the farthest position. In this position, the
dome lamps remain on whether a door is opened or
closed.
Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
k(Dome Off):
Press the button in and the dome
lamps remain off when a door is opened. Press the
button again to return it to the extended position so that
the dome lamps come on when a door is opened.
4-14

Entry Lighting
The vehicle has an illuminated entry feature.
When the doors are opened, the dome lamps will
come on if the dome override button is in the extended
position. If the dome override button is pressed in,
the lamps will not come on.
Exit Lighting
The interior lamps come on when the key is removed
from the ignition. They turn off automatically in
20 seconds. The lights do not come on if the dome
override button is pressed in.
Front Reading Lamps
The reading lamps are located on the overhead
console.
To turn the reading lamps on or off, press the button
located next to each lamp.
The lamps can be adjusted to a desired direction.
The vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the button
located next to the lamp. These lamps are fixed and
cannot be adjusted.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets.
4-15

EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER
ACTIVE, BATTERY VOLTAGE LOW, or LOW
BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical loads
as much as possible. SeeDIC Warnings and Messages
on page 4‑56.
Battery Run-Down Protection
This feature shuts off the dome, and reading lamps if
they are left on for more than 10 minutes when the
ignition is off. This will keep the battery from
running down.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two under the climate controls, one inside the
center floor console, one on the rear of the center floor
console and one accessory power outlet in the rear
cargo area on the passenger side.
To use an accessory power outlet, remove the
protective cap. When not in use, always cover the
accessory power outlet with the protective cap.
The accessory power outlets are powered, even with
the ignition off. Continuing to use accessory power
outlets while the ignition is in LOCK/OFF may cause the
vehicle's battery to run down.
Notice:If electrical devices are left plugged into a
power outlet, the battery may drain causing the
vehicle not to start or damage to the battery. This
would not be covered by the vehicle warranty.
Always unplug all electrical devices when turning
off the vehicle.
