Before driving
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
be
en 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
m
ay be affected, preventing the smart a ccess system with push-button start and
wireless remote control from operating properly. (Way of coping; P. 4 8 6 )
●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 or other wireless communica -
tion devices
●When multiple electronic keys has come into contact with, or is covered by a
metallic object
●When multiple electronic keys are in the vicinity
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle's electronic key
• A wireless key that emits radio waves
• Personal computer
●If window tint with a metallic content or metallic object are attached to the rear
window

1-7. Safety information
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision, when the vehicle impacts straight into a fixed barrier 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 thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbags will not activate, if there is no passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
heavy luggage is put, even if the seat is unoccupied. ( P. 7 2 )
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield ai rbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS front side airbag on the passenger seat will not activate, if there is no
passenger sitting in the front passenger seat. However, the front side airbag on
the passenger seat may deploy, if heavy luggage is put, even if the seat is unoc-
cupied. ( P. 7 2 )
■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.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
