Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag or airbag
sensor assembly. Doing so may pre-
vent the front airbag system from
activating correctly, cause sudden
activation of the system or disable
the system, resulting in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
SRS front airbag system in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front

SECTION 1 7

158
This active height control 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
“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 the
bumpy roads and through water.
This mode is available when the vehicle
speed is under about 30 km/h (19 mph).
CAUTION
The “HI” (high) or “Extra high” mode
should be used for severe offroad
driving condition only. Because the
vehicle’s center of gravity is higher in
this setting, the vehicle may become
unstable when turning abruptly, re-
sulting 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 accor-
dance with the driving condition. When the vehicle exceeds the specified
vehicle speed, the vehicle height
changes to the following:
With the fourwheel 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 fourwheel 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.

(c) Vehicle height mode changingcondition
To change the vehicle height, it is nec-
essary to meet the following 3 condi-
tions.
The engine should be running.
All the side doors and back door
should be closed.
The height control “OFF” indicator
light should go off.
When selecting a mode with the four −
wheel drive control lever at “H”, there is
a vehicle speed limit. Refer to the follow-
ing table.
Yes = The mode can be selected.
No = The mode cannot be selected.

In the following cases the active height
control suspension does not operate
even if the above conditions are all
met.
The brake pedal has been depressed
for longer than about 5 seconds with
the vehicle stopped.
The suspension fluid temperature is
lower than –30 C (–22 F). If the en-
gine is warmed up, the suspension
fluid temperature will be raised as the
inside of the engine compartment be-
comes warmer. Then the active height
control system becomes operable.
Driving on the bumpy roads, which
may cause the suspension to fully
elongate.
The steering wheel is operated abruptly
more than 3/4 turns with center differ-
ential lock system activated.
(d) Vehicle height adjustment
To change the mode, push the height
select switch on either side of
“
”(higher) and “”(lower).
The height control indicator light indicates
which mode is selected. (See “(f) Height
control indicator lights” described below.)

161
NOTICE
If you change the vehicle height fre-
quently, the pump may overheat. To
prevent this, the active height con-
trol suspension should be stopped
temporarily for a minute between
selections. Operate it again.
 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 active
height control suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
The vehicle height cannot be raised if
the vehicle load exceeds the following
limits:
Up to 4 occupants∗ plus about 280 kg
(617 lb.) in the normal mode
Up to 4 occupants∗ plus about 150 kg
(331 lb.) in the high mode
∗: About 75 kg (165 lb.) for a person
If the above load capacity is exceeded,
the desired vehicle height may not be ob-
tained even if the height select switch is
pushed. (If the vehicle height cannot be
raised in the normal mode and the height
control indicator indicates “LO”, this is be-
cause the vehicle is loaded too heavily.
Under these conditions, drive your vehicle
with due care.)
If the vehicle height cannot be raised
even after unloading, push the height se-
lect switch on the “
” side and then on
the “
” side. If this does not work, turn
off the ignition once and then turn on.
Operate the select switch again.
If the vehicle height is adjusted on the
slope, or with the selector lever in a posi-
tion other than “P” or “N” while the vehicle
is stopped, you may hear a sound caused
by the expansion and contraction of the
propeller shaft. Selecting the high mode—
Push the height select switch on the “
”
side when the vehicle speed is under
about 30 km/h (19 mph).
To change the normal mode to high,
push the switch once.
To change the low mode to high, push
the switch twice. It takes about 30 se-
conds until the low mode changes to the
high mode.
Selecting the normal mode—
To change the high mode to normal,
push the height select switch on the “
”
side once.
To change the low mode to normal,
push the height select switch on the “
”
side once.
Selecting the low mode—
Push the height control switch on the
“
” side while the vehicle is stopped.
To change the high mode to low, push
the switch twice.
To change the normal mode to low,
push the switch once.

162
NOTICE
Do not select the low mode in the
bumpy roads. If the underbody of the
vehicle touches the rugged road sur-
face, the vehicle may be damaged.
Even if the engine is stopped while the
vehicle height is being lowered, the op-
eration continues for up to 12 seconds.
(e) Turning off the active height controlsuspension
To turn off the active height control
suspension with the vehicle stopped,
push the height control switch. The
height control “OFF” indicator light
comes on and the vehicle height is
fixed in the same mode as the height
control switch is pushed.
This status is memorized in the system
even after the engine is stopped.
If you push the switch again, the height
control “OFF” indicator light goes out and
the active height control suspension is
turned on.
CAUTION
If you drive through deep water over
about 500 mm (20 in.) in depth, put
the vehicle height in the HI (High)
mode with the active height select
switch and then turn off the active
height control suspension by pushing
the height control switch. Drive your
vehicle at 30 km/h (19 mph) or lower
speed.
NOTICE
 When jacking up or insta lling tire
chains, be sure to turn off the ac-
tive height control suspension and
stop the engine. Otherwise, the ve-
hicle height may change because of
the automatic leveling function, re-
sulting in an accident.
 If your vehicle must be towed, put
the vehicle height in the normal
mode and turn off the active height
control suspension. Otherwise, the
vehicle height may change because
of the automatic leveling function,
resulting in an accident.
