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 your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are three ways to cancel the cruise control:
Step lightly on the brake pedal.
Slide the lever on the multifunction lever to the
OFF position.
Press the COAST and ACCEL buttons at the
same time.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
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
3-14

The exterior lamps control has three positions:
Off:Push the control all the way in to turn off the
exterior lamps.
Parking Lamps:Pull the control out halfway to turn
on the parking lamps together with the following:
Taillamps
License Plate Lamps
Instrument Panel Lights
Headlamps:Pull the control all the way out to turn on
the headlamps together with the previously listed
lamps and lights. SeeInterior Lamps on page 3-17for
information on the instrument panel brightness
control and on the dome lamps. A warning chime will
sound if you open the driver’s door when the ignition
switch is off and the headlamps are on.
Daytime Running Lamps/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 isn’t covered.
The DRL system’s automatic headlamp control will
make your high-beam headlamps come on at a reduced
brightness when the following conditions are met:
The ignition is on,
the exterior lamps control is off and
the gearshift is not in PARK (P).
When the DRL are on, only your high-beam headlamps,
at a reduced level of brightness, will be on. The
headlamps, taillamps, sidemarker and other lamps won’t
be on. Your instrument panel and cluster won’t be lit
up either.
When it’s dark enough outside, your high-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, your headlamps will
go off and your DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Delayed Headlamps
The delayed headlamps feature provides a period of
exterior lighting as you leave the area around your
vehicle. The feature is activated when the headlamps
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 either a 30 second or
60 second 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.
To disable the delayed headlamps feature or change
the time of delay, seeVehicle Customization Settings on
page 3-97.
Fog Lamps
If your vehicle is equipped
with fog lamps, the button
is located on the
instrument panel next to
the exterior lamps
control wheel to the left of
the steering column.
Your ignition must be in ON for the fog lamps to
illuminate.
To turn the fog lamps on, press the FOG button. A light
will come on in the button to let you know that the
fog lamps are on. Press the FOG button again to turn
the fog lamps off.
The ignition must be ON and the parking lamps must be
on for your fog lamps to work.
The fog lamps will go off while you change to high-beam
headlamps.

Interior Lamps
Instrument Panel Brightness
The control for the instrument panel lights is located on
the exterior lamps control. Your parking lamps must
be on for this feature to work. Turn the control clockwise
to brighten the lights or counterclockwise to dim them.
Courtesy Lamps
When any door is opened, several lamps come on. These
lamps are courtesy lamps. They make it easy for you to
enter and leave your vehicle. You can also turn these
lamps on by turning the exterior lamps control all the way
clockwise.
Entry Lighting
Your vehicle may be equipped with courtesy lamps that
will come on and stay on for a set time whenever
you press UNLOCK on the remote keyless entry
transmitter (if equipped).
If you open a door, the lamps will stay on while it’s open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don’t open
a door, the lamps will turn off after about 40 seconds.Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps don’t just 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 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 won’t 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 moved to ON,
the doors are locked, or
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.
3-17

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 moved to ON,
the power door locks are activated, or
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.
Parade Dimming
The instrument panel has an added feature called
parade mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you’ll still be able to see
the displays.
Reading Lamps
Your vehicle may be equipped with reading lamps that
are located on the assist handles in the headliner.
These lamps and the interior courtesy lamps come on
when any door is opened. Press the lens to turn them on
and off.
Dome Lamp
If your vehicle has this feature, the dome lamp will
come on when you open a door. You can also turn this
lamp on by turning the exterior lamps control clockwise
as far as it will go. Vehicles that have the optional
sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor
vanity lamps or trunk lamp. If you leave any of these
lamps on, they will automatically turn off after
10 minutes, if the ignition is off. The lamps won’t come
back on again until you do the following:
Turn the ignition on, or
turn the exterior lamps control off, then on again.
If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
ash three times. They will remain on for one more
minute before turning off automatically.

Manual Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode allows for approximately a
50/50 split of air to the instrument panel outlets and
to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets, with some of the air directed to the
windshield and side window outlets. In this mode, the
system will automatically select Outside Air.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging and
Defrosting” later in this section.
By positioning the right knob between two modes, a
combination of those two modes is selected.It should be noted, that the air conditioning compressor
will be engaged unless the outside temperature is
40° F (4°C) or below. Recirculation cannot be selected
when in Floor Mode.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the airow seems low when the fan is at the highest
setting, the passenger compartment air lter, if
equipped, may need to be replaced. For more
information, seePassenger Compartment Air Filter on
page 3-25andScheduled Maintenance on page 6-4.
:(Outside Air):Press this button to turn the
outside air mode on. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light in the button will
come on to let you know that it is activated. The outside
air mode can be used with all modes, but it cannot
be used with the recirculation mode.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.
3-21

?(Recirculation):This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or help heat or
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on. When the button
is pressed, an indicator light will come on.
You may have to set the instrument panel brightness
control to the highest setting during the day to see the
indicator lamp.
The recirculation mode cannot be used with outside
air modes.
D or P (Temperature Control):Slide the levers
marked D (Driver) or P (Passenger) to increase or
decrease the temperature on the driver’s side or
the passenger’s side of the vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When A/C is pressed,
an indicator light will come on to let you know that
the air conditioning has been activated.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the
air inside of your vehicle has cooled, turn the
recirculation mode off.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
