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 control 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 “LO” 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 height control
mode select switch, and check that manu-
al control mode indicator light comes on.
Then, remove the obstruction.
CAUTION
If you drive through water, set the
vehicle height to “HI” with the height
control switch and then change to
manual control mode by pushing the
height control mode select switch. Do
not exceed 30 km/h (18 mph) or “HI”
mode will automatically change to
“N” mode. Do not drive through water
deeper than about 700 mm (28 in.)
even if the vehicle height is in “HI”
mode.
NOTICE
When jacking up or insta lling tire
chains, be sure to set manual con-
trol mode by pushing the height
control mode select switch and stop
the engine. Otherwise, the vehicle
height may change because of the
automatic leveling function, result-
ing in an accident.

(e) Parking and stopping tips
If you immediately stop the engine to park
the vehicle after off−road driving, the ve-
hicle height is lowered slightly as the ve-
hicle becomes cool. When parking, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you park the vehicle for a long time,
the vehicle height may be gradually low-
ered. When parking for a long time, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you stop the engine, the vehicle height
may change in accordance with the
change in the temperature. When you
start the engine, the vehicle returns to the
previous height. (f) Rear height control failure warning
If there is a problem somewhere in the
rear height control air suspension, “N”
mode is automatically selected. If this oc-
curs, the manual control mode indicator

eling function is turned off. When the ve-
hicle height is changed because of the
conditions (load etc.), you can adjust the
vehicle height with the height control
switch.
In manual control mode, if the vehicle
speed exceeds 30 km/h (18 mph), auto-
matic control mode is activated and “N” is
selected automatically.
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 and remove the obstruc-
tion.
CAUTION

(b) Vehicle height adjustment
To change the vehicle height in manual
mode, push the height control switch
on either side of “ ” (higher) or “”
(lower).
A higher vehicle height is suitable when
driving on bumpy roads and through water.
A lower vehicle height allows for easy
access to the vehicle (getting in and out)
and easy loading and unloading.
When you are driving on bumpy roads,
which may cause the suspension to fully
elongate, the rear height control air sus-
pension may not operate.

To raise the vehicle height—
Push the “” side of the switch for two
seconds or more. Each time you push the
switch, the vehicle height increases. When
the vehicle height is about 20 mm (0.8
in.) higher than the standard height, the
“HI” indicator light comes on.
The maximum selectable height is about
40 mm (1.6 in.) higher than the standard
height.
To lower the vehicle height—
Push the “ ” side of the switch. Each
time you push the switch, the vehicle
height decreases.
Tw o −wheel drive models—
When the vehicle height is about 7.5 mm
(0.3 in.) lower than the standard height,
the “LO” indicator light comes on.

one or more doors open, make sure that
there is nothing that might come into con-
tact with the vehicle body or around the
doors.
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. This does not indicate a
malfunction.
CAUTION
The higher vehicle height should be
only set for severe offroad 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 “N” 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 control 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

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.If the low tire pressure warning light
comes on or blinks, do the following.
If the warning light comes on:
Stop your vehicle in a safe place as
soon as possible and check that the
inflation pressure of all tires (including
the spare tire) is as specified on the
tire and loading information label. (See
“Checking tire inflation pressure” on
page 431 in Section 72.) If the warning
light comes on even after tire inflation
pressure adjustment, you may have a
flat tire. If you have a flat tire, replace
it with the spare tire. For details, see
“If you have a flat tire” on page 389 in
Section 4.
The warning light goes off a few minutes
after air is put into the deflated tire.
This warning light may turn on due to
natural causes such as natural air leaks
or tire pressure changes caused by tem-
perature. In this case, adjusting the tire
pressure will turn off the warning light.
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Depending on the conditions, re-
duce to an appropriate speed as
soon as possible.
Adjust the tire pressure to the spe-
cified level as soon as possible.
Avoid abrupt steering wheel maneu-
vering and braking. Tire deteriora-
tion may reduce steering wheel con-
trol and brake effectiveness. This
may lead to serious injury or death.
The tire pressure warning system
may not activate immediately if sud-
den bursts of air leakage occur.

NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected by
the installation or removal of tires.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.
If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non −genuine Toyota wheels are used.
The sensor battery is expired.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.
CAUTION
The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.
