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
ªCOLDº range. Similarly, if it is hot, the
fluid level should be in the ªHOTº range.
If the level is at the low side of either
range, add automatic transmission fluid
DEXRONII 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.
Keep your tire inflation pressures
at the proper level.
The recommended cold tire inflation
pressures, tire sizes and the com-
bined weight of occupants and cargo
(vehicle capacity weight) are de-
scribed on page 454 and 458. The
recommended cold tire inflation pres-
sures and tire sizes are also de-
scribed on the tire information label.
You should check the tire inflation
pressure every two weeks, or at least
once a month. And do not forget the
spare!

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
The following instructions for
checking tire inflation pressure
should be observed:

The pressure should be
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading.

If you cannot adjust the tire
pressure when the tires are
cold, add 20 to 30 kPa more to
the front tires and rear tires than
the cold tire pressure, but never
exceed the maximum cold tire
pressure molded on the tire side-
wall.

Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.

Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.Tire pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE
1. Remove the tire valve cap.
2. Press the tip of the tire pressure
gauge to the tire valve.
3. Read the pressure using the grad-
uations of the gauge.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too
much air, press the center of the
valve and release the air to adjust.

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
5. After completing the tire inflation
pressure measurement and ad-
justment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not avail-
able, have your vehicle checked by
your Toyota dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire inflation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure (underinfla-
tion)Ð

Excessive wear

Uneven wear

Poor handling

Possibility of blowouts from an
overheated tire

Poor sealing of the tire bead

Wheel deformation and/or tire
separation

A greater possibility of tire
damage from road hazards
High tire pressure (overinfla-
tion)Ð

Poor handling

Excessive wear

Uneven wear

A greater possibility of tire
damage from road hazards

REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load 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,
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 side wall of the
tire and the Certification Label, see
pages 347 and 345.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.

Do not mix radial, bias belted,
or bias±ply 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.

Four±wheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.
For vehicles with vehicle stability
control systemÐ

Do not use tires of different
brands, sizes and construc-
tions. This may damage the
drive system and prevent the
vehicle skid control system
from functioning correctly.

Toyota recommends all four tires,
or at least both of the front or rear
tires be replaced at a time as a set.
See ªIf you have a flat tireº on page
387 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 replaced
w i t h a new on e.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires.
See ªTire pressure warning sys-
temº on page 198 in Section 1±7.

2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
To equalize the 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 ªSched-
uled Maintenance Guideº or ªOwn-
er's Manual Supplementº.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See ªIf you have a flat tireº on page
387 in Section 4 for tire change proce-
dure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out±
of±balance wheels, or severe braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See ªTire pressure warning sys-
temº on page 198 in Section 1±7.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 four±wheel 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.

Four±wheel 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.

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.

Four±wheel drive models:
Do not use wheels of different
brands, sizes and types, as this
may cause dangerous handling
characteristics resulting in loss of
control.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your wheels. See ªTire
pressure warning systemº on page 198
in Section 1±6.
When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).

If you have rotated, repaired or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).

When using tire chains, be careful not
to damage the aluminum wheels.

Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.

When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.

As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
