Turn 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.
To signal a lane change, raise or lower the lever
for less than one second until the arrow starts
to flash. This will cause 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 will return by itself when
it is released.
