STARTING AND DRIVING

BRAKE PAD WEAR INDICATORS
SS31030
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have
the brake pads checked and replaced by your nearest Lexus
dealer immediately.
Avoid continuous driving with the warning noise.
Continuous driving without replacing the brake pads will cause
expensive rotor damage and increasing brake pedal effort to
get the same stopping distance.
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.

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.)

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.
