Cruise Control
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).
If you apply the brakes, the cruise control shuts off.
{CAUTION:
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.

Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brake is applied, this shuts off the cruise control.
But it does not need to be reset.
Once the vehicle is going about 25 mph (40 km/h) or
more, move the cruise control switch briey from
RtoS.
The vehicle returns to the previously chosen speed
and stays there.
If the switch is held on resume/accelerate, the vehicle
keeps going faster until the switch is released or
the brakes are applied. So unless you want the vehicle
to go faster, do not hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the desired
speed. Press
Tat the end of the lever, then
release the button and the accelerator pedal.
The vehicle will now cruise at the higher speed.
Move the cruise switch fromRtoS. Hold it there until
the vehicle reaches the desired speed and then
release the switch. To increase the vehicle speed in
small amounts, move the switch briey to resume/
accelerate. Each time this is done, the vehicle goes
about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
PressTat the end of the lever until the desired
speed is reached, then release it. 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 cruise control speed set earlier.
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 may want to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. When the brakes are
applied the cruise control will disengage.
3-12

Ending Cruise Control
There are three ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to9.

Headlamps on Reminder
A reminder tone sounds when the headlamps or
parking lamps are manually turned on, if the driver’s
door is open and the ignition is in LOCK/OFF or
ACC/ACCESSORY. To turn the tone off, turn the knob
all the way counterclockwise.
In the automatic mode, the headlamps turn off once the
ignition key is in LOCK/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 DRL are required on all vehicles
rst sold in Canada.
The DRL system makes the headlamps come on at
reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamps knob is in automatic
headlamp mode.
The light sensor detects daytime light.
The transmission is not in P (Park).When the DRL are on, only the headlamps will be on.
The taillamps, sidemarker, instrument panel lights
and other lamps will not be on.
When it begins to get dark, the headlamps automatically
switch from DRL to the regular headlamps.
Automatic Headlamp System
When it is dark enough outside, the Automatic
Headlamp System turns on the headlamps when
the vehicle is started and after the transmission
has been shifted out of the P (Park) position.
The headlamps, taillamps, sidemarker, and parking
lamps will come on. The instrument panel lights
and radio lights will also turn on at normal brightness.
Once on, the system remains on during these conditions
even if the vehicle is shifted back into P (Park).
The vehicle has a light sensor on the top of the
instrument panel. Do not cover the sensor or the system
may come on whenever the ignition is on and the
vehicle is shifted out of the P (Park) position.
The system could also turn on the lamps when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
3-14

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 are only 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 comes on after the transmission
is shifted out of P (Park). Once the vehicle leaves the
garage, it takes about one minute for the automatic
headlamp system to change to DRL if it is light outside.
During that delay, the instrument panel cluster might
not be as bright as usual. Make sure the instrument
panel brightness control is in the full bright position.
If the vehicle is running and the automatic headlamp
system is already on, it can be turned off by turning and
releasing the headlamp control at the off position.
The automatic headlamp system stays off until you turn
and release the headlamp control at the off position
again. SeeHeadlamps on page 3-13.Fog Lamps
The fog lamp button is located on the instrument panel
to the right of the exterior lamps knob. Use the fog
lamps for better vision in foggy or misty conditions.
The ignition must be in ON/RUN for the fog lamps
to work.
#:Press to turn the fog lamps on or off. An indicator
light turns on near the button while the fog lamps
are on. Fog lamps turn off whenever the high-beam
headlamps are on.
Some localities have laws that require the headlamps
to be on along with the fog lamps.

next to the exterior lamps
knob to extend it.
Turn the knob to adjust the instrument panel lights.
Turn the knob all the way up to turn on the interior
lamps. Press the knob back into its stored position when
you are not using it.
Dome Lamps
The dome lamps come on when a door is opened,
unless the dome lamp override button is pressed in.
Dome Lamp Override
The dome override button is located below the exterior
lamps knob.
E:Press to turn the dome lamps off. The dome lamps
will remain off when a door is open. This overrides
the illuminated entry feature unless the Remote Keyless
Entry (RKE) transmitter is used to unlock the vehicle.
Press the button again to return the lamps to automatic
operation. The dome lamps will come on when a
door is opened.
Entry Lighting
The vehicle has entry lighting.
When any door is opened, the dome lamps come on
as long as the dome override lamp override button is not
pressed in. When all the doors are closed, the lamps
stay on for a short period of time and then turn off
automatically. If you use the Remote Keyless Entry
(RKE) transmitter to unlock the vehicle, the interior
lamps come on for a short time whether or not the dome
lamp override is on.
3-16

Exit Lighting
With exit lighting, the interior lamps come on when you
remove the key from the ignition. If the dome override
is off, these lamps stay on for a short period of time and
then go out.
Reading Lamps
The reading lamps are located in the front console.
Press the lens on the lamps to turn the reading lamps
on or 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 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.
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 3-51.
3-17

Battery Run-Down Protection
This feature shuts off the dome, courtesy, and vanity
lamps if they are left on for more than 20 minutes when
the ignition is off. This helps to keep the battery from
running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to ON/RUN.
This feature also turns off the parking lamps and
headlamps under most circumstances, if they
are left on. Turn the exterior lamps knob to turn
them back on.
Accessory Power Outlet(s)
Accessory power outlets let you plug in auxiliary
electrical equipment, such as a cellular telephone.
The vehicle has three accessory power outlets.
There are two outlets located below the climate
controls and one outlet is on the rear of the center oor
console.Remove the cover from the outlet to use the outlet.
Be sure to put the cover back on when not using the
accessory power outlet.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adaptor fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power outlets.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle 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 the 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.
