Turn and
Lane-Change Signals
Move the lever all the way up
or down to signal a turn.
An arrow on the instrument
cluster will flash in the
direction of the turn or lane
change.
Raise or lower the lever until
the arrow starts to flash to
signal a lane change. Hold it
there until the lane change is
complete. If the lever is moved
momentarily to the lane
change position, the arrow will
flash three times. It will flash
six times if Tow/Haul Mode is
active.
The lever returns to its
starting position when it is
released.
If after signaling a turn or lane
change, the arrow flashes
rapidly or does not come on, a
signal LED may be burned out.
See your dealer for service.
If a LED is not burned out,
check the fuse. See
