10_IS250C/350C_U
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start from
operating properly:
(Ways of coping: →P. 5 0 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When another wireless key (that emits radio waves) is being used nearby
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
●If window tint with a metallic content or metallic objects are attached to the rear
window
●Immediately after the retractable hardtop is opened or closed

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)

Before driving
10_IS250C/350C_U
■SRS airbag deployment conditions (side airbags)
●The SRS side airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to the impact force produced
by a 3300 lb. [1500 kg] vehicle colliding with the vehicle cabin from a direc-
tion perpendicular to the vehicle orientation at a speed of 12 - 18 mph [20 - 30
km/h]).
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. However, the side airbag on the passen-
ger seat may deploy if luggage is put in the seat, even if the seat is unoccupied.
(→ P. 111)
■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the side
●Collision from the rear
●Vehicle rollover
