The brake actuator temperature increases
during the active traction control system
or vehicle stability control system operat-
ing. If the brake actuator temperature be-
comes too high while the active traction
control system or vehicle stability control
system is operating, a buzzer will start to
sound intermittently to indicate that the
active traction control system can no lon-
ger operate. In this case, immediately stop
your vehicle at a safe place. If the system
continues to operate, the buzzer sound
changes from intermittent to continuous.
(The continuous buzzer sounds for about
3 seconds.) At the time, the “VSC/TRAC”
warning light will come on and the active
traction control system temporarily stops
operating in order to protect the brake
actuator. (Although the active traction con-
trol system does not operate, there is no
problem to continue your driving.) The
system will be automatically restored after
a short time and “VSC/TRAC” warning
light goes off if the accelerator pedal is
released.
When the “ABS” warning light come on,
the active traction control system is not
operating.
The “VSC/TRAC” warning light will come
on when the ignition key is turned “ON”,
and will go off after a few seconds.The “VSC/TRAC” warning light may stay
on for 60 seconds after the ignition key
is turned to “ON” position. It is normal if
it goes off after a few seconds.
Depressing the brake pedal repeatedly
may turn on the “VSC/TRAC” warning
light. It is normal if it goes off after a few
seconds.
When the “VSC/TRAC” warning light
comes on the active traction control sys-
tem is not operating, but there is no prob-
lem if you continue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light does not
come on after the ignition key is turned
“ON”.
The “VSC/TRAC” remains on after the
ignition key is turned “ON”.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicles and
power to 4 wheels may not be main-
tained, even though the active trac-
tion control system is in operation.
Do not drive the vehicle under any
speed or maneuvering conditions
which will cause the vehicle to lose
traction. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the road conditions pres-
ent.

151
SYSTEM MALFUNCTION
If the low tire pressure warning light
blinks, it indicates a system malfunc-
tion. Contact your Toyota dealer.
The system will be disabled in the condi-
tions below:
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
If a radio set at similar frequencies is
in use.
Much snowflakes or ice gets on the
vehicle, in particular, around the wheels
or wheel housings.
Non−genuine Toyota wheels are used.
Snow tires or tire chains are used.
The sensor battery is expired.
The tires not equipped with tire pres-
sure sensor are used.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.
Although the tires are equipped with
tire pressure sensors, the selector
switch (see page 154) is set to other
tire setting.
NOTICE
 The use of nongenuine wheels will
cause the tire pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the fail-
ure of the system.
 The use of tires other than origi-
nally installed with genuine wheels
may also cause the malfunction of
the system.
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
NOTICE:
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable protec-
tion against harmful interference in a
residential installation. This equipment
generates, uses and can radiate radio
frequency energy and, if not installed
and used in accordance with the instruc-
tions, may cause harmful interference to
radio communications. However, there is
no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interfer-
ence to radio or television reception,
which can be determined by turning the

CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
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 antilock
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.
“ABS” warning light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on.

257
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“P” and block the front wheels. Do not
use the parking brake, or snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Dinghy towing
30c001a
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.
Trailer towing
Your vehicle is designed primarily as a
passenger−and− load− carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
CAUTION
Vehicles with active height control
suspension system: When disconnect-
ing a trailer, put the vehicle height in
the “LO” (Low) mode and push the
height control switch to turn off the
active height control suspension.
Otherwise, the vehicle height may be
changed in the automatic leveling
function, resulting in an accident. For
details, see “Active height control
suspension” on page 158.

SECTION 7 2

324 Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label. For details about the
sidewall of the tire and the Certifica-
tion Label, see pages 238 and 236.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.
Do not mix radial, bias belted,
or biasply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use tires other than the
manufacturer’s recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
 Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.
Toyota recommends all four tires,
or at least both front or rear tires
be replaced as a set.
See “If you have a flat tire” on page
275 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle handling and tire life. Wheels
can get out of balance with regular
use and should therefore be balanced
occasionally.
When replacing a tubeless tire, the
air valve should also be repl aced
w i t h a new on e.

325
Rotating tires
To equalize tire 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 “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.See “If you have a flat tire” on page
275 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire infla-
tion pressure, improper wheel align-
ment, out
−of −balance wheels, or se-
vere braking.
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, all the tires must be the same
brand and have the same tread pat-
terns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
Installing snow tires and
chains

326
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
size, as this may cause dangerous
handling characteristics resulting in
loss of control.
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 rear 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 space.
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 105 km/h (65 mph)
with any type of snow tires.
Cross chainSide chain
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Use the following type chains.
For P275/60R18 111H tire
mm (in.)
A Diameter of side chain: 3.5 (0.14)
B Diameter of cross chain: 4.0 (0.16)
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
