CAUTION
■SRS airbag precautions
●If breathing becomes difficult after the SRS airbag has deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so
will disperse the passenger’s weight, which prevents the sensor from detecting
the passenger’s weight properly. As a result, the SRS front passenger airbag may
not deploy in the event of a collision.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications with-
out consulting your Lexus dealer. The SRS airbags may malfunction or deploy
(inflate) accidentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rail
●Repairs or modifications of the front fender, front bumper, or side of the occupant
compartment
●Installation of snow plows, winches, etc. to the front grille (bull bars, kangaroo bar
etc.)
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios or CD players
●Modifications to your vehicle for a person with a physical disability

ing wheel operation in conjunction with VGRS, EPS and active stabilizer
suspension system (if equipped).
Sports mode
For winding mountain road driv-
ing or high speed driving.
Normal mode
For normal driving.

CAUTION
■The hill-start assist control may not operate effectively when
●On steep inclines.
●On icy surfaces.
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
■When TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are systems to ensure vehicle stability and driving force, do not turn off TRAC
and VSC unless necessary.
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the specified tire pres-
sure level.
The ABS and VSC will not function correctly if different tires are fitted on the vehi-
cle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause the system to malfunction.
