2000 TOYOTA SIENNA ground clearance

00 SIENNA(U)
216
The compact spare tire saves space in
your luggage compartment, and its lighter
weight helps to improve fuel economy and
permits easier installation in case of a flat
tire.
The compact spare tire can be used many
times, if necessary. It has tread life of up
to 4800 km (3000 miles) depending on
road conditions and your driving habits.
When tread wear indicators appear on the
tire, replace the tire.
See also the tire section in Section 7−2
for details on the tread wear indicators
and other service information.
CAUTION
The compact spare tire was de-
signed especially for your Toyota.
Do not use it on any other vehicle.
Do not exceed 80 km/h (50 mph)
when driving with the compact
spare tire.
Avoid sudden acceleration, sudden
deceleration and sharp turns with
the compact spare tire.
NOTICE
Your ground clearance is reduced
when the compact spare tire is
installed so avoid driving over ob-
stacles and drive slowly on rough,
unpaved roads and speed bumps.
Also, do not attempt to go through an
automatic car wash as the vehicle
may get caught, resulting in damage.
1. Get the required tools and spare
tire.
1. Jack
2. Jack handle
3. Wheel nut wrench
4. Spare tire
To prepare yourself for an emergency, you
should familiarize yourself with the use of
the jack, each of the tools and their stor-
age locations.

—Loosening wheel nuts
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
The nuts turn counterclockwise to loosen.
To get maximum leverage, fit the wrench
to the nut so that the handle is on the
right side, as shown above. Grab the
wrench near the end of the handle and
pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet—just unscrew
them about one−half turn.
—Positioning the jack
5. Position the jack at the correct jack
point as shown.
Make sure the jack is positioned on a
level and solid place.
CAUTION
When jacking up the vehicle, turn off
the power sliding door system and
close the sliding door completely.
—Raising your vehicle
6. After making sure that no one is in
the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the jack touches the vehicle
and begins to lift, double−check that it is
properly positioned.

(a) Towing with wheel lift type truck
From front—Release the parking brake.
NOTICE
When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle
will be damaged during towing.
From rear—
Use a towing dolly under the front wheels.
NOTICE
Never tow a vehicle with an automatic
transmission from the rear with the
front wheels on the ground, as this
may cause serious damage to the
transmission.
(b) Using flat bed truck
(c) Towing with sling type truck
(c) Towing with sling type truck

Checking and replacing tires
Tread wear indicator
CHECKING YOUR TIRES
Check the tires tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built−in
tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a techni-
cian and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should examine
the damage. Objects which have pene-
trated the tire may have caused internal
damage.
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 only the
same size and construction as original-
ly installed and with the same or great-
er load capacity.
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
Do not mix radial, bias belted, or
bias−ply tires on your vehicle. It
can cause dangerous handling char-
acteristics, resulting in loss of con-
trol.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size.
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See “If you have a flat tire” 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.

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 damaged wheels, the
tire may slip off the wheel or they may
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.
This must be observed on compact spare
tires, too.
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.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your wheels. See ”Tire
pressure warning system” in Section
1−8.
Aluminum wheel precautions
After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.
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 the 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.
