(a) Vehicle height modes
D "HI" (high) mode
The vehicle height is about 40 mm (1.6 in.) higher at front
and about 50 mm (2.0 in.) higher at rear than the normal
mode height.
This mode is suitable when driving on bumpy roads and
through water.
This mode is available when the vehicle speed is under about
30 km/h (19 mph).
STARTING AND DRIVING
CAUTION
The "HI" (high) or "Extra high" mode should be used for
severe off road driving condition only. Because the
vehicle's center of gravity is higher in this setting, the
vehicle may become unstable when turning abruptly,
resulting in an accident.
When the four wheel drive control lever is put at "L", this mode
may change to the extra high mode automatically in
accordance with the driving condition.
When the vehicle exceeds the specified vehicle speed, the
vehicle height changes to the following:
With the four wheel drive control lever at "H" and at the
vehicle speed of 30 km/h (19 mph) or over, the normal mode
is automatically selected.
With the four wheel drive control lever at "L" and at the
vehicle speed of 50 km/h (30 mph) or over, the vehicle
height becomes automatically about 25 mm (1.0 in.) higher
than the normal mode height. If the vehicle speed is lowered
about 20 km/h (12 mph) or less after that, the high mode
automatically resumes.

Extra high mode

This mode is automatically selected from the high mode
with the four wheel drive control lever placed in "L"
position depending on the vehicle driving condition.
If the vehicle becomes stuck, the vehicle height rises
automatically to the extra high mode (slightly higher or at about
70 mm (2.8 in.) higher than normal mode height).
