Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Push in the SET button until you reach the lower
speed you want, then release it.

To slow down in very small amounts, push the
SET button briefly. Each time you do this, you'll
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 cruise control speed you set earlier.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 find this to
be too much trouble and don't use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal, or

move the cruise switch to OFF.
Erasing Cruise Speed Memory
When you turn off the cruise control or the ignition,
or shift into PARK (P) or NEUTRAL (N), your cruise
control set speed memory is erased.

Exterior Lamps
The lamp controls
are located on the
instrument panel.
They control these systems:

Headlamps

Taillamps

Parking Lamps

License Lamps

Sidemarker Lamps

Instrument Panel Lights

Courtesy LampsIf you pull the knob out halfway, it will turn on your
parking lamps and your other operating lamps. If you
pull the knob all the way out, your headlamps will then
come on.
Push the knob in all the way to turn off the lamps.
A warning chime will sound if you open the driver's
door when you turn the ignition switch to OFF, LOCK
or ACC with the lamps on.
Daytime Running Lamps / Automatic
Headlamp Control
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 lights are required on all vehicles first 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 will make your front turn signal lamps
come on when:

The ignition is on,

the headlamp switch is off and

the parking brake is released.

2-43
When the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.
When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's 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 front turn signal lamps will come on.
To idle your vehicle with the DRL and automatic
headlamp control off, set the parking brake while the
ignition is in OFF or LOCK. Then start your vehicle.
The DRL, headlamps and parking lamps will stay off
until you release the parking brake.
To turn off the automatic headlamp feature when it's
dark outside, move the exterior lamp control to the
parking lamp position. Your parking lamps will remain
illuminated and your headlamps will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Delayed Headlamp Illumination
Delayed headlamp illumination provides a period of
exterior lighting as you leave your vehicle's area. The
feature is activated when your vehicle's headlamps are
on due to the automatic headlamp control feature
described previously in this section, and when your
vehicle's ignition is turned off. Your headlamps will
then remain on until the headlamp switch is moved from
OFF to the parking lamp position or until a 90 second
lighting period has ended.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the delayed
headlamp illumination cycle will not occur.
You can customize the vehicle to activate delayed
headlamp illumination when your vehicle's ignition
is turned off under the conditions described above,
or you may choose not to activate this feature under
any conditions.

2-44
You can turn the feature on and off when you perform
the following sequence:
1. Turn the ignition key to RUN.
2. Close all the doors.
3. Press and hold the power door lock switch. While
holding the door lock switch, cycle the headlamp
switch on and then off two times.
4. Release the power door lock switch. These steps
must be carried out in a time period of less than
10 seconds, followed by a delay period of no more
than 10 seconds.
5. Then, press and hold the power door unlock switch.
While holding the door unlock switch, turn the
headlamp switch on and then off two times. Release
the courtesy door unlock switch. These operations
must be carried out in a time period of less than
10 seconds.
After releasing the door unlock switch, a single chime
will be heard if the delayed headlamp illumination
function has been disabled; two chimes will be heard
if the feature has been enabled. Disconnecting the
vehicle's battery for up to a year will not change the
programmed operation of this feature.Interior Lamps
Instrument Panel Brightness Control
You can brighten or dim the instrument panel lights by
moving the LIGHTS knob. If you turn the knob past
MAX, your courtesy or interior lamps will come on.
Courtesy Lamps
When any door is opened, several lamps come on. These
lamps are courtesy lamps. They make it easier to see as
you enter and exit your vehicle. You can also turn these
lamps on by twisting or turning the interior lights knob
all the way to the right.
Illuminated Entry
Your courtesy lamps will come on and stay on for a
set time whenever you press UNLOCK on the remote
keyless entry transmitter.
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.

2-45
Illuminated entry 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 RUN
or START, so 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 lights your vehicle's interior for
a period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting to
work. Just 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 RUN, or

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.
Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the ignition key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the ignition key is removed, interior
illumination will activate and remain on until one
of the following occurs:

The ignition is in RUN, or

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.
Rearview Mirror Reading Lamps
The reading lamps are located on the underside of the
rearview mirror.
Use the switch next to each lamp to turn them on
and off.
Dome Lamp (If Equipped)
The dome lamp will come on when you open a door.

2-46 Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp, underhood lamp or glove box
lamps on. If you leave any of these lamps on, they will
automatically turn off after 20 minutes, if the ignition is
in OFF. The lamps won't come back on again until you
do one of the following:

Turn the ignition on,

turn the lamp switch off, then on, or

open a door.
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.
Retained Accessory Power (If Equipped)
With retained accessory power, your power windows,
audio system and sunroof (if equipped) will continue to
work up to 10 minutes after the ignition key is turned
to OFF and before any of the doors are opened.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.

mirror to turn this feature on. The mirror will darken
gradually to reduce glare from headlamps behind you.
This may take a few moments.
The mirror's two outer buttons operate the lights on
the bottom sides of the mirror.

2-48
One photocell on the front of the mirror senses when
it is becoming dark outside. Another photocell, facing
rearward, senses headlamps behind you. To turn the
electrochromic feature off, press the button in the

2-49 Power Outside Foldaway Mirrors
The power mirror controls
are located near the
driver's side window,
on the armrest.
To choose either the left or right outside mirror, move
the top switch from left through neutral to right. Press
any of the four buttons located on the control pad
below the top switch to move the mirrors in the
desired direction.
Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle.
These mirrors can also be folded rearward manually.
This feature is particularly useful in automatic car
washes and when maneuvering your vehicle in
narrow spaces.
Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from
the driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.

2-50 Automatic Dimming/Heated Outside
Rearview Mirror (If Equipped)
With this feature, the driver's side outside mirror
will adjust for the glare of headlamps behind you.
This feature is controlled by the on and off settings
on the electrochromic automatic dimming rearview
mirror. (See ªElectrochromic Automatic Dimming
Rearview Mirrorº earlier in this section.)
The left and right outside mirrors are also heated when
you activate the rear window defogger. (See ªRear
Window Defoggerº in the Index.)
Both outside mirrors can be folded forward or rearward.
This feature is particularly useful in automatic car washes.
