The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Windshield Wipers
Windshield Washer
Flash-To-Pass Feature.
Information for these features is on the pages following.
For vehicles with the side blind zone alert system, an
arrow in the outside mirror flashes when the turn signal
is used. See Side Blind Zone Alert (SBZA) on
page 3 39 for more information.
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 complete. If the lever is briefly pressed and released,
the turn signal will flash three times.
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 bulb may be
burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. See Fuses and Circuit Breakers on
page 6 110.
An arrow on the
instrument panel
cluster flashes in the
direction of the turn or
lane change.
