f i r n and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is finished, the lever will
return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
L
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
As
you signal a turn or a lane change, if the arrows
don't flash but just stay on, a signal bulb may be
burned out and other drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the fuse (see "Fuses and Circuit
Breakers" in the Index) and for burned-out bulbs.
If you have a trailer towing option with added wiring
for the trailer lamps, a different turn signal flasher is
used. With this flasher installed, the signal indicator
will flash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this indicator light on
the instrument panel also
will be on.
