1: Mode select switch
2: Height select switch
This rear height control air suspension
controls the vehicle height depending
on vehicle driving conditions.
You can choose automatic control mode
or manual control mode. In automatic
control mode, you can select the ve-
hicle height between ªHIº (high), ªNº
(normal) and ªLOº (low) modes with the
height select switch. In manual control
mode, you can adjust the vehicle height
seamlessly with the height select
switch.
To change the mode between automatic
control mode and manual control mode,
use the mode select switch.The vehicle height is automatically ad-
justed to a selected height mode. Howev-
er, when the front drive control is in ª4LOº
mode, the vehicle height cannot be ad-
justed automatically even if the vehicle
condition changes, but height mode can
be changed manually with the height se-
lect switch.
(a) Vehicle height modes
ªNº (normal) modeÐ
The vehicle height in this mode is stan-
dard. Regardless of the number of occu-
pants or the luggage loading condition, the
vehicle height is always automatically ad-
justed to a fixed height in this mode while
the engine is running.
This mode is suitable for ordinary driving.
ªHIº (high) modeÐ
The vehicle height is about 40 mm (1.6
in.) higher at rear than ªNº mode height.
This mode is suitable when driving on
bumpy roads and through water.
However, when the vehicle speed exceeds
30 km/h (18 mph) in ªHIº mode, ªNº mode
is automatically selected.
CAUTION
ªHIº mode should be only used for
severe off±road driving conditions.
Because the vehicle's center of gravi-
ty is higher in this setting, the ve-
hicle may become unstable when
turning abruptly, resulting in an acci-
dent.

ªLOº (low) modeÐ
Two±wheel drive modelsÐThe vehicle
height is about 15 mm (0.6 in.) lower at
rear than ªNº mode height.
Four±wheel drive modelsÐThe vehicle
height is about 30 mm (1.2 in.) lower at
rear than ªNº mode height.
This mode allows for easy access to the
vehicle (getting in and out) and easy load-
ing and unloading.
This mode is available when the vehicle
speed is 12 km/h (7 mph) or less.
NOTICE
Use ªLOº mode when the vehicle is
stopped. Otherwise, when the vehicle
speed exceeds 12 km/h (7 mph), ªNº
mode is selected automatically. Prop-
er caution should be taken in places
where the overhead height is limited.
(b) Vehicle height mode changing con-
dition
To change the vehicle height, it is neces-
sary to meet the following conditions.
The engine should be running.
The manual control mode indicator light
should go off.
When selecting a mode, there is a ve-
hicle speed limit. Refer to the following
table.
Yes = The mode can be selected.
No = The mode cannot be selected.

However, when you are driving on bumpy
roads, which may cause the suspension to
fully elongate, the rear height control air
suspension may not operate.
If the vehicle height is adjusted on the
slope, or with the selector lever in a posi-
tion other than ªPº or ªNº while the vehicle
is stopped, you may hear a sound caused
by the expansion and contraction of the
propeller shaft. This does not indicate a
malfunction.

NOTICE
If the vehicle height is changed fre-
quently when the vehicle is heavily
loaded, the compressor may over-
heat, causing the vehicle height ad-
justment operation to stop.
Before you lower the vehicle height
with the height select switch, check
under the vehicle to make sure
nothing to damage the vehicle or
no one to be injured is there and
that the underbody of the vehicle
does not touch the ground.
After unloading, the height of a ve-
hicle equipped with the rear height
control air suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
Do not select ªLOº mode for bumpy
roads. If the underbody of the ve-
hicle touches the road surface, the
vehicle may be damaged.
