spare tire Lexus IS300 2002 Pictorial Index / LEXUS 2002 IS300 WAGON OWNER'S MANUAL (OM53423U)

STARTING AND DRIVING
252
LIMITED±SLIP DIFFERENTIAL
Some vehicles are equipped with a limited±slip differential. If
one rear wheel begins to spin, the limited±slip differential is
designed to aid traction by automatically transmitting driving
force to the other rear wheel. If you are not sure whether your
vehicle is equipped with one, you can ask your Lexus dealer.
CAUTION
Do not start or run the engine while your vehicle is
supported by a jack. The vehicle could be driven off the
jack and could pose a danger or result in serious injury.
NOTICE
Use only a spare tire of the same size, construction and
load capacity as the original tires on your Lexusbecause damage to the limited±slip differential couldpossibly occur with another tire type.

IN CASE OF AN EMERGENCY
269
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 wheel
design and color and special wording ºTEMPORARY USE
ONLYº molded into the side wall of the tire.
The standard tire should be repaired and replaced as soon as
possible.
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 ºChecking
and replacing tiresº on page 326.)
CAUTION

The compact spare tire was designed especially for
your Lexus. 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 obstaclesand drive slowly on rough, unpaved roads and speedbumps. Also, do not attempt to go through an automatic
car wash as the vehicle may get caught, resulting in damage.

When closing the board, replace the hook also in its
original position as shown.
NOTICE
If you close the back door with the board hooked, thehook may be damaged.
Spare tire with turning direction indicators
(Some models)
SV41014
The spare tire with turning direction indicators is of a
uni±directional type and is intended for use on the
passenger side of the vehicle.
Installing the wheel on the driver side of the vehicle will not
affect tire performance. If the spare tire is used on the driver
side of the vehicle, it should be used only temporarily and then
replaced with the correct one.

1Joint
2When removing the jack, turn the joint by hand in the
ºcontractº direction until the jack is free.
3 When storing, turn the joint by hand in the ºexpandº
direction u ntil the jack is firmly secured to prevent it from
flying forward during a collision or sudden braking.
SV41028
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.

4. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.
SV41031
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.

CAUTION
The reservoir may be hot so be careful not to burn
yourself.
NOTICE
Avoid overfilling, or the power steering could bedamaged.
When adding the power steering fluid, avoid spillingit. The generator under the power steering reservoircould be damaged if fluid is spilled on it.
CHECKING TIRE PRESSURE
SV61004
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least once a month. And don't forget the spare! The pressure
for the spare tire should be the same with that for the standard
tire. Incorrect tire pressure can reduce tire life and make your
vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.

CHASSIS
326Before
storing radial, snow or studded tires, mark the direction
of rotation and be sure to install them in the same direction
when using them again. Tires should be stored in a cool dry
place.
SV63009

With the 215/45ZR17 tires for front and the
225/45ZR17 tires for rear
Do not perform rotation of the tires, from front to rear or
from left to right, or using the spare tire, performing such
tire rotation may result in the tires interfering with the
body or in uneven wear of the tires, so that steerability of
the vehicle is impaired.
CHECKING AND REPLACING TIRES
When to replace your tires
SV63006

1New tread 2Tread wear indicator
3Worn tread
Replace the tires when the tread wear indicators show.
The location of the tread wear indicators is shown by the
ºTWIº or º
Dº marks molded on the sidewall of each tire.
The tires on your Lexus 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 replaced.
