Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or
down. The lever returns automatically when the turn
is complete.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it there until the lane
change is complete. The lever returns to its original
position when it is released.
Rapid ashing of arrows when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeFuses and Circuit Breakers on page 5-104for
