NOTICE
If you spill the fluid, be sure to wash
it off with water to prevent it from
damaging the parts or paint.If cold O.K.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60 C—80 C or 140 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 C—30 C or 50 F—85 F) if the engine
has not been run for about five hours. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the “COLD”
range. Similarly, if it is hot, the fluid level
should be in the “HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II
or III to bring the level within the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir cap, visually check the steering box
case, vane pump and hose connections
for leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.

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.
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.

Fluid type: Toyota Genuine ATF Type TIV
Change automatic transmission fluid only
as necessary.
Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF Type TIV”
(ATF JWS3309 or NWS6500) to aid in
assuring optimum transmission perfor-
mance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
Type TIV” may cause deterioration in
shift quality, locking up of your trans-
mission accompanied by vibration, and
ultimately damage the automatic trans-
mission of your vehicle. Please contact your Toyota dealer for fur-
ther details.
