WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel
movements, such as sharp lane
charges or fast, sharp turns.
o The risk of rollover is greatly in-
creased if you lose control of
your vehicle at highway speeds.
o In a collision crash, an unbelted
person is significantly more likely
to die a person weara seatbelt.
o Loss of control often occurs if
two or more wheels drop off the
roadway and the driver oversteers
to reenter the roadway.
o In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pull-
ing back into the travel lanes.
4WD LOCK SYSTEM
C360A01O-GAT
(With Electronic Control 4WD)
(If installed)
This 4WD system is designed for divid-
ing the power ratio automatically in
normal driving conditions.
During off-road or low-friction driving
conditions, press the 4WD lock button
to drive in full-time 4WD, dividing the
power ratio to 50:50 in the front and
rear wheels. The 4WD lock indicator
light in the instrument cluster is illumi-
nated.
This setup begins to get cancelled
when the vehicle speed exceeds 30
km/h, and the function is completely
released at a speed of 40 km/h or
higher. Conversely, the function is re-
OJM019056
run when the speed again drops to 40
km/h or lower, and is fully established
at speeds below 30 km/h.
To release the 4WD lock function,
press the 4WD lock button again.
The 4WD lock indicator light in the
instrument cluster should go off.
1) Pressing the 4WD lock button on
the tough terrain, the driving power
is equally distributed to the front
and rear.
4WD lock keeps activating when
not exceeding 40 km/h.
2) Release the 4WD lock button on
the normal driving conditions.

Four Wheel Drive (4WD) transfer mode selection
Transfer mode Selection button Indicator light Description
o This mode is used for climbing or descending sharp
grades, off-road driving, driving on sandy and muddy
roads etc. to maximize traction.
o This mode automatically begins to deactivate at speed
above 30 km/h and is shifted to 4WD AUTO mode at
speed above 40 km/h. If the vehicle decelerates to
speeds below 30 km/h, however, the transfer mode is
shifted into 4WD LOCK mode again.
o When driving in AUTO mode, the vehicle operates similar
to the conventional 2WD vehicles under normal operating
conditions. However, if the system determines that there
is a need for the 4WD mode, the engine’s driving power
is distributed to all four wheels automatically without
driver intervention.
o When driving on normal roads and pavement, the vehicle
moves similar to the conventional 2WD vehicles.

NOTE:
o When driving on normal roads, deactivate the 4WD LOCK mode by pushing the 4WD LOCK button(the indicator light
goes off). Driving on normal roads with 4WD LOCK mode(especially, when cornering) may cause mechanical noise
or vibration. The noise and vibration will disappear when the 4WD LOCK mode is deactivated. Some parts of the
power train may be damaged by prolonged driving with the noise and vibration.
o When the 4WD LOCK mode is deactivated, a shock may be felt as the drive power delivered entirely to the front
wheels. This shock is not a mechanical failure.
