Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete. The lever returns to its original
position when it’s released.Arrows that ash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s won’t see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. SeeFuses
and Circuit Breakers on page 5-96for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km), a
warning chime will sound and the Turn Signal On
message will appear on the Driver Information Center
(DIC) display. See “Turn Signal On” underDIC Warnings
and Messages on page 3-65for more information.

is 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 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 about 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
