the mirror. An arrow on the mirror will ash in
the direction of the turn or lane change.
Ground Illumination Lamps

the driver’s outside mirror will adjust for the glare
of headlamps behind you. This feature is
controlled by the on and off settings found on the
electrochromic inside mirror. SeeAutomatic

Outside Curb View Assist Mirrors
If your vehicle has the memory package, the
outside mirrors are able to perform the curb view
assist mirror function. This feature may be
useful in in allowing the driver to view the curb
when parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R).
The passenger’s and/or driver’s mirror will return to
its original position when the vehicle is shifted out of
REVERSE (R) and either a thirty second delay has
occurred, the vehicle speed is greater than 8 mph
(12 km/h), or the ignition is turned to off.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDriver
Information Center (DIC) on page 260for more
information.

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close the sunroof, the ignition
needs to be turned to ON, or Retained Accessory
Power (RAP) must be active. When RAP is active,
the sunroof will work for 10 minutes after the
ignition is turned off, or until a front door is opened.
SeeRetained Accessory Power (RAP) on page 141
for more information.
There are two switches
in the overhead console

Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower speed is
reached, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time you do this, the vehicle will
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 previous set cruise
speed.
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 the vehicle’s speed. When going
downhill, you may have to brake or shift to a lower
gear to keep the vehicle’s speed down. Of
course, applying the brake takes you out of cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering
wheel.
Erasing Speed Memory
When you turn off the cruise control or the
ignition, the cruise control set speed memory is
erased.

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
The exterior lamps control has four positions:
9(Off):Turn the control to this position to turn
off the automatic headlamps and daytime
running lamps (DRL). Turning the headlamp
control to the off position again will turn the
automatic headlamps or DRL back on.
For vehicles rst sold in Canada, the off position
will only work for vehicles that are shifted into
the PARK (P) position.AUTO (Automatic):Turn the control to this
position to automatically turn on the headlamps at
normal brightness, together with the following:
Parking Lamps
Instrument Panel Lights

automatically 10 minutes after the ignition is
turned off. When the headlamps are turned on
while the vehicle is off, the headlamps will continue
to stay on. Turn the control to the off position to
turn the headlamps off or the battery will be
drained.
215

A warning chime will sound if you open the
driver’s door when the ignition switch is off and
the headlamps are on.
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
Headlamps on Reminder
A reminder chime will sound when the headlamps
or parking lamps are manually turned on and
your ignition is off and a door is open. To disable
the chime, turn the light 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. 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.The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker, and other lamps
will not be on. The instrument panel will not be
lit up either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transaxle
must be in the PARK (P) position, before the DRL
lamps can be turned off.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
216

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position
and then release. For vehicles rst sold in Canada,
the transaxle must be in the PARK (P) position,
before the automatic headlamp system can
be turned off.
The vehicle has a light sensor located on the top
of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the headlamps
will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.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 will only
be affected when the light sensor detects a change
in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 219.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 280.
As with any vehicle, you should turn on the regular
headlamp system when needed.
