1-2. Opening, closing and locking the doors and trunk
IS350/250_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. 4 9 3 )
●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

1-7. Safety information
IS350/250_U
■SRS airbag deployment conditions (front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to an approximately 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. 1 0 4 )
■SRS airbag deployment conditions (side and curtain shield airbags)
●The SRS side airbags and SRS curtain shield 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 an approximately 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle ori-
entation at an approximate 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. 1 0 4 )
■Conditions under which the SRS airbags ma y 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.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judged by the sensor to be closer than they
are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your
vehicle
