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.

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.
If you attempt to adjust the vehicle height
with anything such as snow, ice, or stones
in contact with the vehicle body, the ve-
hicle height may not change. In this case,
stop the vehicle, press the mode select
switch, and check that manual control
mode indicator light comes on. Then, re-
move the obstruction.
CAUTION

vehicle height to ªHIº with the height
select switch and then change to
manual control mode by pushing the
mode select switch. Do not exceed 30
km/h (18 mph) or ªHIº mode will au-
tomatically change to ªNº mode. Do
not drive through water deeper than
about 700 mm (28 in.) even if the
vehicle height is in ªHIº mode.
NOTICE

When jacking up or installing tire
chains, be sure to set manual con-
trol mode by pushing the mode se-
lect switch and stop the engine.
Otherwise, the vehicle height may
change because of the automatic

the vehicle height to ªNº and
change to manual control mode.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.

40 mm (1.6 in.) higher than the standard
height.

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.
CAUTION
The higher vehicle height should be
only set for severe off±road driving
conditions. Because the vehicle's cen-
ter of gravity is higher in this setting,
the vehicle may become unstable
when turning abruptly, resulting in an
accident.
NOTICE

When lowering the vehicle, the ve-
hicle must be stopped. Otherwise,
when the vehicle speed exceeds 30
km/h (18 mph), automatic control
mode is activated and ªNº is se-
lected automatically. Proper caution
should be taken in places where the
overhead height is limited.

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
