1-7. Safety information
10_IS250C/350C_UIn certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chem
ical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side airbag sensor assemblies, driver's seat position sensor, driver's seat belt buckle
switch, seat belt pretensioner assemblies, inflators, interconnecting wiring and
power sources. ( →P. 4 6 4 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel, airbag cover and inflator) as well as
the front seats may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (front airbags)
●The front SRS airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to a 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. ( →P. 111)

4-1. Maintenance and care
10_IS250C/350C_U
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not apply water. Excellent
results are obtained when keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→ P. 1 0 1 )
Electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or severe injury.

■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( →P. 444)
●If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
■If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
