STARTING AND DRIVING
255
CAUTION
Do not mix summer and all season tires on your
vehicle as this can cause dangerous handling
characteristics, resulting in loss of control.
 Do not use tires other than the manufacturer's
designated tires, and never mix tires or wheels of the
sizes different from the originals.
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 j ack. 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.

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.
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 335.)
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.
 The standard tire should be repaired and replaced as
soon as possible.
 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.

yourself.
NOTICE
Avoid overfilling, or the power steering could bedamaged.

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 may waste fuel, reduce the comfort
of driving, reduce tire life and make your vehicle less safe to
drive.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.
