Controls for the outside
power mirrors are located
on the driver’s door
armrest.
To adjust the mirror:
1. Press the left or right side of the selector switch
located beneath the control pad to choose the
driver’s or passenger side mirror.
2. Press one of the four arrows located on the control
pad to move the mirror in the desired direction.
3. Adjust each outside mirror to see a little of your
vehicle, and the area behind your vehicle.Manually fold the mirrors inward to prevent damage
when going through an automatic car wash. To fold, push
the mirror toward the vehicle. Push the mirror outward, to
return to its original position.
Outside Automatic Dimming Mirror
If the vehicle has this feature, the driver’s side mirror
adjusts for the glare of headlamps behind you.
This feature is controlled by the on and off settings on
the automatic dimming rearview mirror. SeeAutomatic
Dimming Rearview Mirror on page 2-34for more
information.
Turn Signal Indicator
The vehicle may also have a turn signal indicator on the
mirror. An arrow on the outside rearview mirror ashes
in the direction of the turn or lane change. SeeTurn and
Lane-Change Signals on page 3-8for more information.

How the System Works
LDW uses a camera located between the inside
rearview mirror and the windshield to detect the lane
markings.
@(Lane Departure Warning):To turn LDW on and
off, press the LDW control, located by the exterior
headlamp control. An indicator on the control will light
to indicate that LDW is on.
When the vehicle is
started, the LDW symbol,
located in the instrument
panel cluster, will briey
come on to indicate that
the light is operational.LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the system
detects a left or right lane marking. This symbol will
change to amber and ash and three beeps will sound if
you cross a detected lane marking without using the
turn signal.
If the LDW symbol does not appear, LDW is not
currently operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume underDIC Vehicle Customization on page 3-66
for more information.

Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument

To change from high beam to low beam, pull the
turn signal lever toward you.
While the high beams are
on, this light located on the

signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
Pull the turn signal lever toward you briey to
ash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They will stay on as long as you
hold the lever toward you and the high-beam indicator on
the instrument panel cluster will come on.
Windshield Wipers
Turn the band with the wiper symbol on it to control the
windshield wipers.
8(Mist):For a single wiping cycle, hold it on mist
until the wipers start, then release. The wipers stop after
one wipe. For more wipe cycles, hold the band longer.
6(Delay):Use to set the delay time between wipe
cycles. The wiper speed can be set for a long or short
delay between wipes. The closer the band is set to
the top of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low speed.
1(High Speed):For high-speed wiping.
9(Off):Turns the wipers off.
Clear ice and snow from the wiper blades before
using them. If the wipers are frozen to the windshield,
carefully loosen or thaw them. If they become worn
or damaged, replace with new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
The vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically
turn on. SeeWiper Activated Headlamps on page 3-16
for more information.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps also turn off if the
windshield wipers are turned off.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the
lamps are turned 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 daytime running lamps are required
on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.The DRL system makes the low-beam headlamps
turn on at reduced brightness in daylight when
the following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transmission is not in P (Park).
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker and
other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn
on with the headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and the
low-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off position.
The exterior lamps will turn back on automatically when
the transmission is moved out of P (Park). SeeExterior
Lamps on page 3-15for more information.
The regular headlamp system should be turned on
when needed.

Fog Lamps
For vehicles with fog lamps, the 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.
#(Fog Lamps):Press the exterior lamps button
to turn the fog lamps on or off. A light comes on in the
instrument panel cluster to show that the fog lamps
are on. SeeInstrument Panel Cluster on page 3-33.
The ignition must be in the ON/RUN position and
the parking lamps must be on for the fog lamps to
illuminate.
The fog lamps will go off while you change to high-beam
headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
For vehicles with this feature, the cornering lamps come
on when: the headlamps or parking lamps are on, the
vehicle is not in P (Park), and you signal a turn with
the turn signal/multifunction lever. They provide
more light for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition is
turned to LOCK/OFF and a door has been opened. This
protects against draining the battery if the headlamps or
parking lamps are accidentally left on. If you need to
leave the lamps on for more than 10 minutes, use the
exterior lamp control to turn the lamps back on after the
ignition is turned to LOCK/OFF and any door is opened.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights.
The knob for this control is located next to the exterior
lamps control.
Push the knob in and release when it pops out.
Turn the knob clockwise to increase the brightness
of the instrument panel lights and counter clockwise to
decrease the brightness. Turning the knob completely
clockwise to the detent will turn on the courtesy lamps.
