IF YOU HAVE A FLAT TIRE
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. Firmly set the parking brake and put the transmission
in ªPº (automatic) or reverse (manual).
4. Have everyone get out of the vehicle on the side away
from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Follow jacking instructions.
 Do not put any part of your body under a vehicle
supported by a jack. Personal injury may occur.
 Do not start or run the engine while your vehicle
is supported by the jack.
Stop the vehicle on a level firm ground, firmly
set the parking brake and put the transmission
in ªPº (automatic) or reverse (manual). Block
the wheel diagonally opposite to the one being
changed if necessary.
 Make sure to set the jack properly in the jack
point. Raising the vehicle with jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall off the jack and cause
personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
 Use the jack only for lifting your vehicle during
wheel changing.
 Do not raise the vehicle with someone in the
vehicle.
 When raising the vehicle, do not put an object
on or under the jack.
 Raise the vehicle only high enough to remove
and change the tire.
NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.

Compact spare tire (Some models)
SV64025
The compact spare tire is designed for temporary
emergency use only.
The compact spare tire is identified by the distinctive
wording ªTEMPORARY USE ONLYº molded into the
sidewall of the tire.
To keep the compact spare tire noticeable, do not hide
the wheel by a wheel cover or such.
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 ªChecking and replacing tiresº on page
368.)
CAUTION

The compact spare tire was designed especially
for your Lexus. Do not use it on any other
vehicle.
 Do not use more than one compact spare tire at
the same time.
 The pressure for the compact spare tire must be
420 Kpa (4.2 kgf/cm
2
or bar, 60 psi).
 Do not exceed 80 km/h (50 mph) when driving
with the compact spare tire.
 Replace the compact spare tire with the
standard tire as soon as possible.
 Avoid sudden acceleration, sudden
deceleration and sharp turns with the compact
spare tire.

To remove the spare tire:
1Remove the tool tray
2Loosen the bolt and remove it.
When storing the spare tire, place it with the inner side
of the wheel facing up. Then bolt the tire in place and
install the tool tray to prevent the tire from flying forward
during a collision or sudden braking.
SV41033
2. Block the wheel diagonally opposite the flat tire to
keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of
one of the front wheels or behind one of the rear wheels.

3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel nuts counterclockwise to loosen them. 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.
CAUTION
Never use oil or grease on the bolts or nuts. The
nuts may loosen and the wheels may fall off, which
could cause a serious accident.
SV04003
4. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid
surface.

5. After making sure no one is in the vehicle, raise it
high enough so that the spare tire can be installed.
Allow for the fact that you 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.
CAUTION
Never get under the vehicle when the vehicle is
supported by the jack alone.
SS41011
6. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
SL41003
7. Remove the wheel ornament.
When installing the alloy wheels, at this point, remove
the wheel ornament from the flat tire and replace it on the
newly installed tire.

Before putting on the wheel, remove any corrosion on
the mounting surfaces with a wire brush or such.
Installation of wheels without good metal±to±metal
contact at the mounting surface can cause wheel nuts to
loosen and eventually cause a wheel to come off while
driving.
SS41013
8. Reinstall all the wheel nuts finger tight.
Align the holes in the wheel with the bolts. Then lift up the
wheel and get at least the top bolt started through its
hole. Wiggle the tire and press it back over the other
bolts.
Reinstall the wheel nuts and tighten them as much as
you can by hand. Press the tire back and see if you can
tighten them more.
CAUTION
Never use oil or grease on the bolts or nuts. Doing
so may lead to overtightening the nuts and
damaging the bolts. The nuts may loosen and the
wheels may fall off, which could cause a serious
accident. If there is oil or grease on any bolt or nut,
clean it.

9. Lower the vehicle completely and tighten the
wheel nuts.
Turn the jack handle counterclockwise to lower the
vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not
use other tools or any additional leverage other than
your hands, such as a hammer, pipe or your foot. Make
sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown.
Repeat the process until all the nuts are tight.
CAUTION
When lowering the vehicle, make sure all
portions of your body and all other persons
around will not be injured as the vehicle is
lowered to the ground.
 As soon as possible after changing wheels,
have the wheel nuts tightened with torque
wrench to 103 N´m (10.5 kgf´m, 76 ft´lbf.).

10. Reinstall the wheel ornament.
Put the wheel ornament into position and then tap it
firmly with the side or heel of your hand to snap it into
place.
CAUTION
Take due care in handling the ornament to avoid
unexpected personal injury.
11. After changing the wheel, check the air pressure
of the replaced tire. Stow all the tools, jack and flat
tire securely.
If the pressure of the replaced tire is low, drive slowly to
the nearest service station and fill to the correct
pressure.
Do not forget to reinstall the tire valve cap as dirt and
moisture could get into the valve core and possibly
cause air leakage. If the cap is missing, put a new one
on as soon as possible.
This is the same procedure for changing or rotating your
tires.
CAUTION
 When reinstalling a standard tire, take due care
in handling the ornament to avoid unexpected
personal injury.
 Before driving, make sure all the tools, jack and
flat tire are securely in place in their storage
location to reduce the possibility of personal
injury during a collision or sudden braking.
