Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal and the message TURN SIGNAL ON also
appears in the Driver Information Center (DIC). SeeDIC
Warnings and Messages on page 3-52. To turn off
the chime and message, move the turn signal lever to
the off position.
Headlamp High/Low-Beam Changer

change the headlamps from low to high beam, pull the
multifunction lever all the way toward you. Then
release it.
When the high beams are
on, this light on the
instrument panel cluster
also will be on.
Flash-to-Pass
This feature allows you to use your high-beam
headlamps to signal a driver in front of you that you
want to pass. It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not so
far that you hear it click.
If your headlamps are off or on low-beam, your
high-beam headlamps will turn on and stay on as long
as you hold the lever toward you and the high-beam
indicator on the instrument panel will come on. Release
the lever to turn the high-beam headlamps off.
Windshield Wipers
The windshield wipers are controlled by turning the
band with the wiper symbol.

The wipers will stop after one wipe. If more wipes are
needed, hold the band on mist longer.
6Delay:The wiper speed can be set for a long or short
delay between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.

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 the StabiliTrak
®system and begins
to limit wheel spin while you are using cruise control, the
cruise control will automatically disengage. See
StabiliTrak
®System on page 4-5. 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 on the button turns on
when cruise control is on and turns off when cruise
control is off.
3-11

+ 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 your parking brake is set,
or if the master cylinder brake fluid 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 your 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 your steering wheel. The
vehicle will go back to the previous set speed and
stay there.
3-12

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 you do this,
you will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
To reduce your 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 you
do this, 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 your speed.
When you take your foot off the pedal, your vehicle will
slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load, and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you may have to brake or shift
to a lower gear to keep the vehicle’s speed down.
Of course, applying the brake takes you out of cruise
control. Many drivers find 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.
Erasing Speed Memory
When you turn off the cruise control or the ignition, the
cruise control set speed memory is erased.
3-13

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):Briefly turn the control to this position to turn
off the automatic headlamps and daytime running
lamps (DRL). Briefly turn to this position again to turn
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 PARK (P)
position.AUTO (Automatic):Turn the control to this position to
automatically turn on the headlamps at normal
brightness, together with the following:
•Parking Lamps
•Instrument Panel Lights

listed below.
•Parking Lamps
•Instrument Panel Lights
•Taillamps
•License Plate Lamps
3-14

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
continue to stay on. To prevent the battery from being
drained, turn the control to the off position.
A warning chime sounds if the driver’s door is opened
while the ignition switch is off and the headlamps are on.
To change the headlamps from low beam to high
beam, push the turn signal/multifunction lever toward
the instrument panel.
Headlamps on Reminder
If a door is open, a reminder chime sounds when the
headlamps or parking lamps are manually turned on and
the key is out of the ignition. To turn off the chime,
turn the headlamp switch to off or auto and then back
on, or close and re-open the door. In the auto mode, the
headlamps turn off once the ignition is in LOCK/OFF
or may remain on until the headlamp delay ends,
if enabled in the Driver Information Center (DIC). See
“Exit Lighting” underDIC Vehicle Customization on
page 3-60.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
The DRL system will come on in daylight when the
following conditions are met:
•The ignition is on.
•The exterior lamps control is in the AUTO position.
•The shift lever is not in PARK (P).
•The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL, turn the exterior lamp control to the
off position and then release it. For vehicles first sold in
Canada, the transmission must be in the PARK (P)
position, before the DRL can be turned off.
3-15

Automatic Headlamp System
When it is dark enough outside and the headlamp switch
is in AUTO, the automatic headlamp system will turn on
the headlamps at the normal brightness along with other
lamps such as the taillamps, sidemarker, parking lamps,
roof marker 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. For vehicles first sold in Canada, the
transmission must be in the PARK (P) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be 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 will only be affected when
the light sensor sees 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
30 seconds for the automatic headlamp system to
change to DRL if it is light 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. SeeInstrument Panel
Brightness on page 3-16.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Turn the knob
clockwise or counterclockwise to brighten or dim
the instrument panel lights and the radio display.
This only works if the headlamps or parking lamps
are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
3-16

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 next to
the exterior lamps control, 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.
The dome lamp override is used to set the dome lamps
to remain off or come on automatically when a door
is opened.
E(Dome Lamp Override):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.
Entry/Exit Lighting
Your vehicle has an illuminated entry/exit feature.
When a door is opened or the key is removed from the
ignition, the dome lamps will come on if the dome
override button is in the out position.
Reading Lamps
For vehicles with reading lamps, press the button
located next to each lamp to turn it on or off.
Your vehicle may also have reading lamps in other
locations. To turn each one on or off, press the button
located next to the lamp. The lamps 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.
3-17

When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or 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 loads are on: headlamps, high beams, rear
window defogger, climate control fan at high speed,
engine cooling fans, trailer loads, and loads plugged into
accessory power outlets.
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.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are left on
for more than 10 minutes when the ignition is in LOCK.
This will help prevent the battery from running down.
Accessory Power Outlet(s)
Your vehicle may have two accessory power outlets
located on the instrument panel.
To use the outlet lift the cover. The spring cap cover
closes by itself when the outlet is empty.
Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power plugs.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating of 20 amperes.
Check with your dealer/retailer before adding
electrical equipment.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
