In manual control mode, the automatic lev-
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
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.
 If your vehicle must be towed, set
the vehicle height to “N” in auto-
matic control mode, then select
manual control mode by pushing
the height control mode select
switch. Otherwise, the vehicle
height may change because of the
automatic leveling function, result-
ing in an accident.
 If your vehicle gets stuck in a
ditch, set manual control mode with
the height control mode select
switch. Otherwise, the vehicle
height may change because of the
automatic leveling function, result-
ing in an accident.
(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.
The minimum selectable height is about
15 mm (0.6 in.) lower than the standard
height.
Four −wheel drive models—
When the vehicle height is about 15 mm
(0.6 in.) lower than the standard height,
the “LO” indicator light comes on.
The minimum selectable height is about
30 mm (1.2 in.) lower than the standard
height. If the underbody of the vehicle has
touched the surface on bumpy roads, the
vehicle height cannot be lowered with the
height control switch.
When adjusting the vehicle height with
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
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.

In the following cases, there is a problem
somewhere in you rear height control air
suspension. Although there is no problem
to continue normal driving, have the rear
height control air suspension checked by
you Toyota dealer as soon as possible.
The height control indicator light and
manual control mode indicator light do
not come on when the ignition switch
is turned on.
The manual control mode indicator light
blinks.
(d) 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.
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.
If you stop the engine, the vehicle height
may change in accordance with the
change in the temperature. (e) Rear height control failure warning
If there is a problem somewhere in the
rear height control air suspension, the
manual control mode indicator light blinks.
If this is the case, change to the automat-
ic control mode by pushing the height
control mode select switch, and bring your
vehicle to your Toyota dealer as soon as
possible to have it checked.
The tire pressure warning system is de-
signed to provide warning when tire
inflation pressure of one or more of
your tires (including the spare tire) is
low. The low tire pressure warning light
comes on to inform you that low tire
inflation pressure may hamper driving.

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.

TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system need
to be initialized in the following condi-
tions:
After replacing or rotating tires or
wheels
After replacing an air pressure sen-
sor.
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard. To initialize the system, perform the fol-
lowing:
1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust the pressure of all the installed tires to the specified level. (See “Tires”
on page 460 in Section 8.)
3. Turn the ignition key to “ON”.
4. Push and hold the reset switch until the low tire pressure warning light
blinks three times.
Initialization is completed or over for more
than 20 minutes.
When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initialization will fail and
the tire pressure warning system will not
function properly. In this case, initialize
the system again.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire pressure is low, or it may
come on when the tire inflation pressure
is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed.

CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)
Use high −quality cassettes.
Low −quality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant auto− reversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.
CARING FOR YOUR COMPACT DISC
PLAYER, DVD PLAYER AND DISCS
Your compact disc player and DVD
player are intended for use with 12 cm
(4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player and DVD
player from working. On hot days, use
the air conditioning to cool the vehicle
interior before you use the players.
Bumpy roads or other vibrations may
make your compact disc player and
DVD player skip.
If moisture gets into your compact disc
player and DVD player, the players
may not play even though they appear
to be working. Remove the disc from
the player and wait until it dries.
CAUTION
