Conditions aff ecting operation
The smart key system uses weak radio waves. In the following situations,
the communication between the electronic key and the vehicle may be
affected, preventing the smart key system, wireless remote control and
immobilizer system from operating properly. (Way of coping P. 621)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
● When carrying a portable radio, mobile phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by the following
metallic 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 other wireless keys (that emit radio waves) are being used nearby
● When carrying 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 computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to
the back window

Conditions aff ecting operation
Vehicles without a smart key system
The wireless remote control function may not operate normally in the follow-
ing situations:
● Near a TV tower, radio station, electr ic power plant, airport or other facil-
ity that generates strong radio waves
● When carrying a portable radio, cell ular phone or other wireless commu-
nication devices
● When multiple wireless keys are in the vicinity
● When the wireless key is in contact with, or is covered by, a metallic
object
● When a wireless key (that emits radio waves) is being used nearby
● When the wireless key has been left near an electrical appliance such as
a personal computer

■ If the wireless remote control does not operate properly (vehicles with
a smart key system)
Locking and unlocking the doors: Use the mechanical key. ( P. 621)
■ Key battery depletion
Vehicles without a smart key system
If the wireless remote control function does not operate, the battery may be
depleted. Replace the battery when necessary. ( P. 552)
Vehicles with a smart key system
 P. 4 6
■ When the electronic key battery is fully depleted
 P. 552
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc, ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.

■SRS airbag deployment conditions (SRS 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 approxi-
mately 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 and 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
vehicle is very close to the designed threshold level, the SRS front air-
bags 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, even if the seat is unoccupied.
■ SRS airbag deployment conditions (SRS 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 pro-
duced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehi-
cle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 - 30 km/h]).
■ SRS airbag deployment condition s (SRS curtain shield airbags)
The SRS curtain shield airbags will deploy in the event of vehicle rollover or
an impact that exceeds the set threshold level (the level of force correspond-
ing 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 orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).

■
Conditions under which the SRS airbags may deploy (inflate), other
than a collision
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.
The SRS curtain shield airbags may also deploy under the situations shown
in the illustration.
■ Types of collisions that may not de ploy the SRS airbags (SRS front air-
bags)
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 collision. But, whenever a collision of any type causes suffi-
cient forward deceleration of the vehicle, deployment of the SRS front air-
bags may occur.
● Hitting a curb, edge of pavement or
hard surface
● Falling into or jumping over a deep hole
● Landing hard or falling

●The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.
●Collision from the side
● Collision from the rear
● Vehicle rollover
