Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals. See
Turn and Lane-Change Signals on page 214.
53Headlamp High/Low-Beam Changer.
SeeHeadlamp High/Low-Beam Changer on
page 215.
Flash-to-Pass. SeeFlash-to-Pass on
page 216.
NWindshield Wipers. SeeWindshield
Wipers on page 216.
LWindshield Washer. SeeWindshield
Washer on page 217.
ICruise Control. SeeCruise Control on
page 217.
For information on the headlamps, seeHeadlamps
on page 221.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will
return automatically.
To signal a lane change, raise or lower the lever
for less than one second until the arrow starts
to ash. This will cause the turn signals to
automatically ash three times. It will ash six
times if tow-haul mode is active. Holding the turn
signal lever for more than one second will
cause the turn signals to ash until you release
the lever. The lever will return by itself when
it is released.

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 226.To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. SeeDaytime Running Lamps
(DRL) on page 222for more information.
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 on page 282.
As with any vehicle, you should turn on the
regular headlamp system when needed.

Mode Control
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets; then directs most
of the remaining air to the oor outlets. A little air
is directed toward the windshield and the side
window outlets. Cooler air is directed to the upper
outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with a little air directed to the
windshield and the side window outlets.

and/or dust from entering your vehicle or to help
cool the air inside of your vehicle more quickly.
Press this button to turn the recirculation mode on
or off. The light on the recirculation button will
illuminate. Recirculation cannot be used in oor,
defog or defrost modes. An indicator on the button
will light up, ash three times and turn off when
recirculation is selected in these modes. The
air-conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or

system in recirculation for extended periods of
time may cause fogging of the vehicle’s windows.
