REAR HEIGHT CONTROL AIR
SUSPENSION
This rear height control air suspension controls the
vehicle height depending on the vehicle driving condition.
Select your desired height among the “HI” (high), “N”
(normal) and “LO” (low) modes with the height select
switch.
(a) Vehicle height modes
“N” (normal) mode: The vehicle height in this mode is
standard. Regardless of the number of occupants or the
luggage loading condition, the vehicle height is always
automatically adjusted to a fixed height in any mode while the
engine is running.
This mode is suitable for ordinary driving.
“HI” (high) mode: The vehicle height is about 40 mm (1.6 in.)
higher at the 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. As the vehicle’s center of gravity
is higher in this setting, the vehicle may become
unstable when turning abruptly resulting in accident.
“LO” (low) mode: The vehicle height is about 20 mm (0.8 in.)
lower at the rear than the “N” mode height.
This mode allows you easy access to the vehicle (getting in and
out) and easy loading and unloading operation.
This mode is available when the vehicle speed is under about
12 km/h (7 mph).
