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 the outside of the res-
ervoir 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.

Some vehicles are equipped with
runflat (RFT) tires. The runflat
tire allows you to continue driving
for up to 160 km (100 miles) at a
speed below 90 km/h (55 mph)
even if any tire goes flat. However,
in some conditions (such as high
temperatures), you could not con-
tinue driving for up to 160 km (100
miles).
When the tire goes flat or when the
tire pressure is below 100 kPa (1.0
kgf/cm
2 or bar, 15 psi), the tire
must be replaced. If you are not
sure, consult your Toyota dealer.
Do not use the repaired tire. There is an “RFT” or “DSST” mark on
the sidewall of the run
−flat tire.
If you cannot distinguish between the
standard tire and run −flat tire, consult
your Toyota dealer.
The tire warranty book provides de-
tailed information on the run −flat tires.
For details, see the tire warranty
book.
CAUTION
 Do not use nongenuine
wheels, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use the runflat tires
equipped on your vehicle on
another model. These tires are
especially for this model.
 Do not mix runflat tires with
standard tires.
If the tire pressure warning light
co mes on :
Decelerate at a speed below 90
km/h (55 mph), then adjust the tire
pressure to the specified level as
soon as possible. Do not drive
more than 160 km (100 miles).
 When the tire pressure is below
140 kPa (1.4 kgf/cm
2 or bar, 20
psi), consult your Toyota deal-
er. If the tire is flat or the tire
pressure is below 100 kPa (1.0
kgf/cm
2 or bar, 15 psi), the tire
must be replaced. Do not use
the repaired tire.
 When the tire pressure is 140
kPa (1.4 kgf/cm
2 or bar, 20 psi)
or more, adjust it to specified
level. (See “Tires” on page 499
in Section 8.)
For details about the tire pressure
warning system, se e “Tire pressure
warning system” on page 196 in Sec-
tion 1 −7.

Vehicles with compact spare tire—
When you replace the tire, see
“—Compact spare tire” through “—Af-
ter changing wheels”, pages 423
through 435 in Section 4.
CAUTION
As the runflat tire allows you to
continue driving if any tire goes
flat, the tire performance is not
the same as normal condition. If
the runflat tire goes flat, take
your vehicle to the nearest Toyo-
ta dealer or authorized tire dealer
as soon as possible, observing
the following instructions:
Decelerate as soon as possible
to the lowest appropriate
speed that conditions permit.
Do not drive for longer than
160 km (100 miles) or over 90
km/h (55 mph).
Avoid abrupt steering wheel
maneuvering and braking. If
t h e veh i cl e ti res det eri o rat e,
you could lose control of the
steering wheel or the brakes,
causing death or serious inju-
ry.
 Do not replace or repair the tire
by yourself. When the tires
must be replaced or repaired,
consult your Toyota dealer or
authorized tire dealer.NOTICE
 Take due care not to go over
a curb stone and be careful
of the holes in the road be-
cause deflated tire pressure
affects tire cushion perfor-
mance. The wheels, tires,
body, suspension and other
components could be dam-
aged.
 Your ground clearance is re-
duced if the runflat tire
goes flat so avoid driving
over obstacles and drive
slowly on rough, unp aved
roads and speed bumps.
Also, do not attempt to go
through an automatic car
wash as the vehicle may get
caught, resulting in damage.

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 allwheel 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.
Allwheel 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 replac-
ing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
Vehicles with runflat tires—Do not
replace or repair the tire by your-
self. When the tires must be re-
placed or repaired, consult your
Toyota dealer or authorized tire
dealer.
