In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.The vehicle skid control system helps
provide integrated control of the sys-
tems such as antilock brake system,
traction control, engine control, etc.
This system automatically controls the
brakes and engine to help prevent the
vehicle from skidding when cornering
on a slippery road surface or operating
steering wheel abruptly.
The vehicle skid control activates when
the vehicle speed is more than the follow-
ing speed.
Front drive control lever in “H”
15 km/h (9 mph)
Front drive control lever in “L4” 30 km/h (18 mph)
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the selfcheck mode but does
not indicate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, you must always drive
carefully and attentively to avoid
serious injury. Reckless driving will
result in an unexpected accident. If
the slip indicator light blinks,
sounding an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 364 in Section 72.)

This section describes some of the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR·VOL” to turn the audio system
on and off.
Push “AM”, “FM”, “TAPE”, “DISC” or
“LOAD” to turn on that function without
pushing “PWR·VOL”. To turn on the cas-
sette or compact disc player, a cassette
or compact disc must be loaded in the
player.
You can turn on each player by inserting
a cassette tape or compact disc.
You can turn off each player by ejecting
the cassette tape or compact disc. If the
audio system was previously off, then the
entire audio system will be turned off
when you eject the cassette tape or com-
pact disc. If the another function was pre-
viously playing, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM”, “TAPE”, “DISC” or
“LOAD” if the system is already on but
you want to switch from one function to
another.

Determine what kind of tires your ve-
hicle is originally equipped with.1. Summer tires
Summer tires are highspeed capab ility
tires best suited to highway driving under
dry conditions.
Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snowcovered or icy roads. For driving on
snowcovered or icy roads, we recom-
mend using snow tires. If installing snow
tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
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 accel-
eration and handling performance
compared with summer tires in highway
driving.CAUTION
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.
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 specification
designated on page 388 in Section 8. If
the pressure is lower, drive slowly to the
nearest service station and fill to the cor-
rect pressure.
Do not forget to reinstall the tire inflation
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 tires—
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 388 in Section 8 with
a torque wrench. Have a technician repair
the flat tire.
With a spare tire of different wheel type
from the installed tires—
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 388 in Section 8 with
a torque wrench. Have a technician repair
the flat tire and replace the spare tire with
it.CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or s udden
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.
Twowheel drive models—Turn 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 “Traction control
system” on page 151 in Section 16.)
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.

If you have tire damage such as cuts,
splits, cracks deep enough to expose
the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be prop-
erly repaired due to the size or location
of a cut or other damage, it should be
replaced. If you are not sure, consult with
your Toyota dealer.
If an air loss occurs while driving, do not
continue driving with a deflated tire. Driv-
ing even a short distance can damage a
tire beyond repair.
Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This also applies to the spare tire and
tires stored for future use.REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater 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.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not mix radial, bias belted, or
biasply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
Do not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
Fourwheel drive models:
Do not use tires of different brands,
sizes, construction or tread pat-
terns, as this may cause dangerous
handling characteristics resulting in
loss of control.
For vehicles with vehicle skid control
system—
Do not use tires of different brands,
sizes and constructions. This may
damage the drive system and pre-
vent the vehicle skid control system
from functioning correctly.

Toyota recommends all four tires, or at
least both front or rear tires be re-
placed as a set.
See “If you have a flat tire” on page 321
in Section 4 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
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 replaced with a
new one.
With a spare tire of the same wheel type
as the installed tires
With a spare tire of different wheel type
from the installed tires
To equalize the wear and help extend
tire life, Toyota recommends that you
rotate your tires according to the main-
tenance schedule. (For scheduled main-
tenance information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.) Howev-
er, the most appropriate timing for tire
rotation may vary according to your
driving habits and road surface condi-
tions.
See “If you have a flat tire” on page 321
in Section 4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, outofbalance
wheels, or severe 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, on fourwheel 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.
Fourwheel 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.
TIRE CHAIN SELECTION
Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check the local
regulations before installing chains.
CHAIN INSTALLATION
Install the chains on the rear tires as
tightly as possible. Do not use tire
chains on the front tires. Retighten
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.
Installing snow tires and
chains

03_SEQUOIA_U (L/O 0301)
368
2003 SEQUOIA from Jan. ’03 Prod. (OM34422U)
CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis. Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use wheels other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
Fourwheel drive models:
Do not use wheels of different
brands, sizes and types, as this
may cause dangerous handling
characteristics resulting in loss of
control.
