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.
The lever returns to its starting
position whenever it is released.
If after signaling a turn or a lane
change the arrows flash rapidly or
do not come on, a signal bulb could
be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See Fuses and Circuit Breakers on
page 10‑41.
Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 mi), a chime will
sound at each flash of the turn
signal and the message TURN
SIGNAL ON will also appear in the
Driver Information Control (DIC).
To turn the chime and message off,
move the turn signal lever to the
off position.
Fog Lamps
For vehicles with fog lamps,
the control is located next to the
exterior lamps control on the
instrument panel, to the left of the
steering column.
The ignition must be in the ON/RUN
position for the fog lamps to
come on.
