Hazard Warning Flashers

(Hazard Warning Flashers):
Press this button located on top of
the steering column, to make the
front and rear turn signal lamps
flash on and off. This warns others
that you are having trouble. Press
again to turn the flashers off.
When the hazard warning flashers
are on, the vehicle's turn signals
will not work.

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 until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed.
Lighting
The lever returns to its starting
position whenever it is released.
If after signaling a turn or 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 39.
Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 miles), a chime
sounds at each flash of the turn
signal and the message TURN
SIGNAL ON also appears in the
Driver Information Center (DIC).
Move the turn signal lever to the
off position to turn the chime and
message off.
