“VSC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle stability control system.
The light will come on when the engine
switch is turned to the “ON” position and
will go off after a few seconds.
If the light comes on while driving, the
systemdoes not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional:
DThe warning light does not come on
after the engine switch is turned to the
“ON” position.
DThe warning light remains on after the
engine switch is turned to the “ON”
position.
DThe warning light comes on while driv-
ing.The vehicle stability controlsystem au-
tomatically controls the brakes and en-
gine to help prevent the vehicle from
skidding when cornering on a slippery
road surface or operating steering
wheel abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 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 self−check mode but does
not indicate a malfunction.
CAUTION
DDo not rely excessively on the ve-
hicle stability controlsystem. Even
if the system is operating, you
must always drive carefully and at-
tentively. Reckless driving will re-
sult in an unexpected accident and
cause death or serious injury. If the
slip indicator light blinks, and spe-
cial care should be taken while
driving.
DOnly use tires of specified size. The
size, manufacture, 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 stability control
system may not function correctly.
When replacing the tires or wheels,
contact any authorized Toyota deal-
er or repairer, or another duly quali-
fied professional. (See “Checking
and replacing tires” on page 270 in
Section 7−2.)
DIn situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tire or tire chains.

STARTING AND DRIVING215
Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 267 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 264 in Section 7−2forrecom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may make starting harder. If you
are not sure about which oil to use, call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified profes-
sional. Follow the manufacturer ’s direc-
tions for how much to mix with water.
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
“M(1)”, “E(1)” or “R” (multi−mode manual
transmission), or into first or reverse
(manual transmission) and block the rear
wheels. Do not use the parking brake,
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, a window scraper,
a bag of sand or salt, flares, a small
shovel, jumper cables, etc.

226IN CASE OF AN EMERGENCY
4. If the coolant is leaking, stop the en-
gine immediately. Call any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profession-
al, for assistance.
5. If there are no obvious leaks, check
the coolant reservoir. If it is dry, add
coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type see “Coolant type
selection” on page 267 in Section 7−2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from
the traffic. Avoid stopping on the center
divider of a highway. Park on a level
spot with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3.Manual transmission:
Firmly set the parking brake and put
the transmission in reverse.
Multi−mode manual transmission:
Securely apply the parking brake and
turn the engine switch “ON”. After the
operation, shift the shift lever to “M(1)”,
“E(1)” or “R”.
4. Have everyone get out of the vehicle
onthesideawayfromtraffic.
5. Read the following instructions thor-
oughly.
CAUTION
When jacking, be sure to observe the
following to help reduce the possibil-
ity of death or serious injury:
DFollow jacking instructions.
DDo not put any part of your body
under a vehicle supported by a
jack. Otherwise, death or serious
injury may occur.
DDo not start or run the engine while
your vehicle is supported by the
jack.
DStop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in reverse.

If you have a flat tire—

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis271
NOTICE
Tires may have damage to its tire
wheel when receiving impact from the
road surface. Therefore, pay attention
to the following.
zBe sure to use with proper tire
inflation pressure. If the tire infla-
tion pressure is low, the tire may
have greater damage. For detailed
information about tire inflation pres-
sure, see page 299.
zAvoid driving onto high, sharp−
edged objects and other road haz-
ards. Failure to do so can lead to
severe tire damage.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16in.).
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
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional.
If air loss occurs while driving, do not
continue driving. Driving even a short dis-
tance could 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 applies also 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.
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.
DDo not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
DDo not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DDo not mix tires of different makes,
models or tread patterns, and do
not mix tires of remarkably different
treadwear. This may cause danger-
ous handling characteristics result-
ing in loss of control.
Never use second−hand tires on your
To y o t a .
Using tires whose previous history is un-
known is a risk.
Toyota recommends all tires be re-
placed at a time as a set.
See “If you have a flat tire” on page 226
in Section 4 for tire change procedure.

TIRE CHAIN SELECTION
Use the tire chains of correct size.
For155/65R14 tires, use the following
type chains.
A Diameter of side chain:
4mm(0.16in.)
B Diameter of cross chain:
5 mm (0.20 in.)
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
NOTICE
If the wrong combination of tire and
chain is used, the chains could dam-
age the vehicle body.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten the
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.
CAUTION
DDo not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
DDrive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
DAvoid sharp turns or locked−wheel
braking as use of chains may ad-
versely affect vehicle handling.
DWhen 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.

Replacing wheels
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 inset
∗.
Correct replacement wheels are available
at your Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional.
∗: Conventionally referred to as “offset”.
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
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
Aluminum wheel precautions
DWhen installing aluminum wheels,
check that the wheel bolts are tight
after driving your vehicle the first1600
km (1000 miles).
DIf you have rotated, repaired, or
changed your tires, check that the
wheel bolts are still tight after driving
1600 km (1000 miles).
DWhen using tire chains, be careful not
to damage the aluminum wheels.
DToyota recommends the use of Toyota
genuine wheel bolts and wrench de-
signed for your aluminum wheels. Oth-
er bolts and wrenches of matching
quality can also be used.
DWhen balancing your wheels, Toyota
recommends the use of Toyota genuine
balance weights. Other balance weights
canalsobeused.
DAs with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
