4-13 Control Functions
WARNING
POTENTIAL HAZARD
Riding too fast while the vehicle is in
4WD-LOCK.
WHAT CAN HAPPEN
All wheels turn at the same speed when
the differential is locked, so it takes more
effort to turn the vehicle. The amount of
effort required is greater the faster you
go. You may lose control and have an
accident if you cannot make a sharp
enough turn for the speed you are
traveling.
HOW TO AVOID THE HAZARD
Always ride at a slow speed when the
vehicle is in 4WD-LOCK, and allow extra
time and distance for maneuvers.
NOTE:
 When the switch is set to "LOCK", the
differential gear lock indicator and
indicator lights will flash until the
differential gear is locked.
 When the differential gear lock indicator
and indicator lights are flashing, turning
the steering wheel back and forth will
help the differential gear lock to engage.
 Riding before the differential gear lock is
properly engaged (e.g., when the
indicator and indicator light are flashing)
will cause the engine speed to be limited
until engagement is complete.
