The cruise control light on the instrument panel cluster
comes 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 speed desired.
3. Press and release the SET– button located
on the steering wheel.
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 previously chosen
speed and stay there.

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle speed.
When you take your foot off the pedal, your vehicle
will slow down to the previously set cruise speed.
Using Cruise Control on Hills
How well your 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
speed. When going downhill, you might have to brake or
shift to a lower gear to keep the vehicle 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.

are on due to the automatic headlamps control
feature described previously in this section, and when
the ignition is turned off. Your headlamps will then
remain on until the exterior lamps control is moved to
the parking lamps position or until the pre-selected
delayed headlamp lighting period has ended.
If you turn off the ignition with the headlamps switch in
the parking lamps or headlamps position, the delayed
headlamps cycle will not occur.

Daytime Running Lamps (DRL)/
Automatic Headlamp System
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 rst sold in Canada.
A light sensor on top of the instrument panel makes
the DRL work, so be sure it is not covered.
The DRL system’s automatic headlamp control will
make the low-beam headlamps come on at a reduced
brightness when the following conditions are met:
The ignition is in the ON/RUN position.
The exterior lamps control is in AUTO.
The engine is running.
When the DRL are on, only the low-beam headlamps,
at a reduced level of brightness, will be on. The
headlamps, taillamps, sidemarker, and other lamps
will not be on. The instrument panel and cluster will
also not be lit.
When it is dark enough outside, the low-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.When it is bright enough outside, the headlamps will
go off and the DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when it is needed.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
-(Fog Lamps):The fog lamps button is located on
the exterior lamps control. The exterior lamps control
is located on the instrument panel to the left of the
steering column.
The ignition must be on for the fog lamps to work.
Press the exterior lamps button to turn the fog lamps
on or off. A light will come on in the instrument
panel cluster when the fog lamps are in use.
When the headlamps are changed to high-beam, the
fog lamps will turn off. The fog lamps come back
on again when the high-beam headlamps are turned off.
Some localities have laws that require the headlamps
to be on along with the fog lamps.

Instrument Panel Brightness
D(Instrument Panel Brightness):The knob with
this symbol on it is located next to the exterior lamps
control. Push the knob in all the way until it extends
out and then turn the knob clockwise to brighten
or counterclockwise to dim the lights. Push the knob
back in when nished.
Courtesy Lamps
When a door is opened, the courtesy lamps automatically
come on. They make it easy for you to enter and leave
your vehicle. You can also manually turn these lamps on
by fully turning the instrument panel brightness control
clockwise.
The reading lamps, located on the headliner above the
rearview mirror, can be turned on or off independent
of the automatic courtesy lamps, when the doors
are closed.
Dome Lamps
The dome lamps automatically come on when a door
is opened, unless the dome lamp override button
is pressed in.
The lamps can also be turned on and off by turning
the instrument panel brightness control clockwise to
the farthest position.
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 Lighting
Your vehicle may have courtesy lamps that will come
on and stay on for a set time whenever the unlock
symbol is pressed on the Remote Keyless Entry (RKE)
Transmitter, if the vehicle has one.
If a door is opened, the lamps stay on while it is open
and then turn off automatically about 25 seconds
after the door is closed. If the unlock symbol is pressed
and you do not open a door, the lamps turn off after
about 20 seconds.
3-17

Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at the end
of the delay time. Instead, they slowly dim after the delay
time until they go out. The delay time is canceled if you
turn the ignition key to ON/RUN or press the power door
lock switch. The lamps will dim right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps will not come on
unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will continue
to work until one of the following occurs:
The ignition is in ON/RUN.
The doors are locked.
An illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON/RUN.
The power door locks are activated.
An illumination period of 20 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the dimming
of the instrument panel displays during the daylight
while the headlamps are on so that you will still be
able to see the displays.
3-18

Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
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 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 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 loads are on: 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.
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 or Service Battery Charging System. 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 3-66.
