lock indicator light goes off before
normal driving.
ªVSC TRACº warning light
This light warns that there is a problem
somewhere in the vehicle stability control
system, traction control system (two±wheel
drive models) or active traction control
system (four±wheel drive models).
The warning light will come on when the
ignition key is turned to ªONº and will go
off after a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.In the following cases, contact your Toyota
dealer:

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

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.

To raise the vehicle heightÐ
Push the ª
º 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
ªHIº indicator light comes on.
The maximum selectable height is about
40 mm (1.6 in.) higher than the standard
height.
To lower the vehicle heightÐ
Push the ªº side of the switch. Each
time you push the switch, the vehicle
height decreases.
Two±wheel drive modelsÐ
When the vehicle height is about 7.5 mm
(0.3 in.) lower than the standard height,
the ªLOº indicator light comes on.
The minimum selectable height is about
15 mm (0.6 in.) lower than the standard
height.
Four±wheel drive modelsÐ
When the vehicle height is about 15 mm
(0.6 in.) lower than the standard height,
the ªLOº 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 select 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 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
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.

Driving with tire chains installed.

Driving over the steps such as the
joints on the road.

Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti±lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels' turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

ªABSº warning light
The light comes on when the ignition key
is turned to the ªONº position. If the anti±
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system, the brake assist
system and the traction control system
and/or the vehicle stability control system
do/does not operate, but the brake system
still operates conventionally.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.

This information has been prepared
in accordance with regulations issued
by the National Highway Traffic Safe-
ty Administration of the U.S. Depart-
ment of Transportation. It provides
the purchasers and/or prospective
purchasers of Toyota vehicles with in-
formation on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
DOT quality gradesÐAll passenger
vehicle tires must conform to Fed-
eral Safety Requirements in addi-
tion to these grades. Quality
grades can be found where appli-
cable on the tire sidewall between
tread shoulder and maximum sec-
tion width. For example: Treadwear
200 Traction AA Temperature ATreadwearÐThe treadwear grade is
a comparative rating based on the
wear rate of the tire when tested un-
der controlled conditions on a speci-
fied government test course. For ex-
ample, a tire graded 150 would wear
one and a half (1±1/2) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate.Traction AA, A, B, CÐThe traction
grades, from highest to lowest, are
AA, A, B, and C, and they represent
the tire's ability to stop on wet pave-
ment as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.

All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 347.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.

Do not use tire other than the
manufacturer's designated
tires, and never mix tires or
wheels of the sizes different
from the originals.

11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specifi-
cation designated on page 458 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into the valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
12.Restow all the tools, jack and
flat tire securely.
With a spare tire of the same wheel
type as the installed tiresÐ
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 458 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire.With a spare tire of different wheel
type from the installed tiresÐ
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 458 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires
or wheels. See ªTire pressure
warning systemº on page 198 in
Section 1±7.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
Two±wheel drive modelsÐTurn off the
traction control system to become un-
stuck to allow the tires to spin enough
to remove the vehicle from the obstruc-
tion. (For details, see ªTraction control
systemº on page 182 in Section 1±7.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.

To equalize the wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the ªSched-
uled Maintenance Guideº or ªOwn-
er's Manual Supplementº.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See ªIf you have a flat tireº on page
387 in Section 4 for tire change proce-
dure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out±
of±balance wheels, or severe braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See ªTire pressure warning sys-
temº on page 198 in Section 1±7.WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Also, on four±wheel drive models, all
the tires must be the same brand and
have the same tread patterns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.

Do not use snow tires other than
the manufacturer 's recommended si-
ze, as this may cause dangerous
handling characteristics resulting in
loss of control.

Four±wheel drive models:
Do not use snow tires of different
brands, sizes, construction or tread
patterns, as this may cause danger-
ous handling characteristics result-
ing in loss of control.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION

Do not drive with the snow tires
incorrectly inflated.

Never drive over 120 km/h (75 mph)
with any type of snow tires.
