(h) Parking and stopping tips
If you immediately stop the engine to park the vehicle after
off−road driving, the vehicle height is lowered slightly as the
vehicle becomes cool. When parking, make sure there is
nothing that will be in contact with the underbody of the vehicle.
If the “HI” (high) mode is selected when you start the engine,
the vehicle returns to the “HI” (high) height. If the “LO” (\
low) or
“N” (normal) mode is selected when you start the engine, the
vehicle height is change to “N” (normal) mode.
If you park the vehicle for a long time, the vehicle height may
be gradually lowered. When parking for a long time, make sure
there is nothing that will be in contact with the underbody of the
vehicle. If the “HI” (high) mode is selected when you start the
engine, the vehicle returns to the “HI” (high) height. If the “LO”\
(low) or “N” (normal) mode is selected when you start the
engine, the vehicle height is change to “N” (normal) mode.
If you stop the engine, the vehicle height may change in
accordance with the change in the temperature. When you
start the engine, the vehicle returns to the “HI” (high) height.\
If the “LO” (low) or “N” (normal) mode is selected when \

TRACTION CONTROL SYSTEM
(twowheel drive models)
The traction control system automatically helps prevent
the spinning of front wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”, the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power against front wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
