"HI" (high) mode—
The vehicle height is about 40 mm (1.6 in.)
higher at rear than the "N" mode height.
This mode is suitable when driving on the
bumpy roads and through water.
However, when the vehicle speed exceeds
about 30 km/h (19 mph) or over in the
"HI" mode, the "N" mode is automatically
selected.
CAUTION
The "HI" 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 accident.
