The headlamps will also stay on
after you exit the vehicle. This
feature can be programmed using
the Driver Information Center (DIC).
See Vehicle Personalization on
page 5 44.
If the vehicle is not equipped
with DIC buttons, exit lighting is
automatic. When it is dark enough
outside, the exterior lamps remain
on for 30 seconds after the ignition
is moved from ON/RUN to
LOCK/OFF.
For vehicles without a radio, the
instrument panel light remains on
for 30 seconds with the driver door
closed. For vehicles with a radio,
the instrument panel light remains
on for 10 minutes with the driver
door closed. See Retained
Accessory Power (RAP) on
page 9 30.
The regular headlamp system can
be turned on when needed.

Turn and Lane-Change

Signals

An arrow on the instrument panel
cluster flashes in the direction of
the turn or lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever for less
than one second until the arrow
starts to flash to signal a lane
change. This causes the turn
signals to automatically flash
three times. It will flash six times if
tow-haul mode is active. Holding
the turn signal lever for more than
one second will cause the turn
signals to flash until you release
the lever.
