VEHICLE STABILITY CONTROLSYSTEM
The vehicle stability control system helps provide
comprehensive control of the systems such as anti-lock
brake system, traction control, engine control, etc. This
system automatically controls the brakes and engine to
help prevent the vehicle from skidding when cornering on
a slippery road surface or operating steering wheel
abruptly.
This system activates when the vehicle speed is about more
than 15 km/h (9 mph).
You may hear a sound in the engine compartment for a few
seconds just after the vehicle begins to move. This means that
the system is in the self-check mode, but does not indicate a
malfunction.
CAUTION
 Do not rely excessively on the vehicle stability
control system. Even if the vehicle stability control
system is operating, you must always drive carefully
and attentively to avoid serious injury. Reckless
driving will result in an unexpected accident. If the
slip indicator light blinks, sounding an alarm, special
care should be taken while driving.
 Only use tires of specified size. The size,
manufacture, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle
stability control system may not function correctly.
When replacing the tires or wheels, contact your
Lexus dealer.
 In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.

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 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.

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 spare tire on the passenger side of the
vehicle will not affect tire performance. However, 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.
CAUTION
SportCross:
 The spare tire was designed especially for your
Lexus. Do not use it on any other vehicle.
 Do not use more than one spare tire at the same
time.
 Do not exceed 80 km/h (50 mph) when driving
with the spare tire.
 The standard tire should be repaired and
reinstalled as soon as possible.
 Avoid sudden acceleration, sudden
deceleration and sharp turns with the spare tire.
