Driving your vehicle

This mode is used for climbing or descending sharp grades,
off-road driving, driving on sandy and muddy roads, etc., to
maximize traction.
This mode automatically begins to deactivate at speeds
above 19 mph (30 km/h) and is shifted to AWD AUTO mode
at speed above 25 mph (40 km/h). If the vehicle decelerates
to speeds below 19 mph (30 km/h), however, the transfer
mode is shifted into AWD LOCK mode again.

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

When driving in AWD AUTO mode, the vehicle operates sim-
ilar to conventional 2WD vehicles under normal operating
conditions. However, if the system determines that there is a
need for the AWD mode, the engine’s driving power is dis-
tributed to all four wheels automatically without driver inter-
vention.
When driving on normal roads and pavement, the vehicle
moves similar to conventional 2WD vehicles.
