Daytime Running Lamps
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 first sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:

It is still daylight and the ignition is in ON
or START,

the exterior lamp control is in OFF or AUTO with
the headlamps off, and

an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.
When DRL are on, only your turn signal lamps will be on.
No other exterior lamps will be on when the DRL are
being used. Your instrument panel won't be lit up either.
When the exterior lamp control is in AUTO and it's dark
enough outside, the DRL will turn off and the low
-beam
headlamps will turn on. When it's bright enough
outside, the low
-beam headlamps will go off, and the
DRL will turn back on.If it's dark enough outside and the exterior lamp control
is in OFF, a Headlamps Suggested message will appear
on the Driver's Information Center (DIC) display. This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are still
illuminated. Turning the exterior lamp control to AUTO
or to the low
-beam headlamp position will turn off the
DRL and cancel the Headlamps Suggested message.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off and the Headlamps
Suggested message will be displayed. You can turn it off
by pressing the OK button if you have the Navigation
audio system or the CLR button if you have the base
audio system.
To operate your vehicle with the DRL off, turn the
exterior lamp control to OFF. Then turn on the fog
lamps or parking lamps, and the DRL will turn off.
The Headlamps Suggested message will appear on the
DIC display. This will work regardless of gear position
and whether or not the parking brake is set.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Light Sensor
The light sensor for the DRL and AUTO headlamp
feature is located on top of the instrument panel. If you
cover the sensor, it will read dark, and the exterior lamps
or the Headlamps Suggested message will appear on the
DIC whenever the ignition is on.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on, the
exterior lamps will turn off approximately 10 minutes
after the ignition is turned to OFF. This protects against
draining the battery in case you have accidentally left
the headlamps or parking lamps on. The battery saver
does not work if the headlamps are turned on after the
ignition is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn
the lamps back on.

Interior Lamps
Instrument Panel Brightness Lever
This feature controls the brightness of the instrument
panel lights.
The lever for this feature
is located on the
overhead console.
Slide the lever toward the symbol to brighten the lights
or away from it to dim them.
If you slide the lever all the way toward the symbol past
the resistance point, the interior lamps will come on. To
turn them off, slide the lever back toward the minimum
brightness setting.
Illuminated Entry
The illuminated entry system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for about
25 seconds. The illuminated entry system uses the light
sensor, it must be dark outside in order for the lamps to
turn on. The lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by sliding the instrument panel
brightness lever toward the symbol to brighten or away
from the symbol to dim the lighting.

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door
is opened.

off 10 minutes after the ignition has been turned off.

Roof Rack Provisions
CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier
-- like paneling, plywood, a mattress, and
so forth
-- the wind can catch it as you drive
along. This can cause you to lose control. What
you are carrying could be violently torn off, and
this could cause you or other drivers to have a
collision, and of course damage your vehicle. You
may be able to carry something like this inside.
But, never carry something longer or wider than
the luggage carrier on top of your vehicle.
Your vehicle is equipped with mounting locations for
the installation of a roof rack or luggage carrier. The
mounting locations are located on the roof rail. You
must open the doors to access them. The threaded nuts
are covered with a plastic cap that must be removed
before use.
For more information on purchasing the rack/carrier as
well as installation information, contact your dealer.
