For safety and security
■SRS airbag deployment condi tions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact tha t exceeds the
set threshold level (the level of force corresponding to an app roximately
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 in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which
can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck
● Depending on the type of collision, it is possible that only th e seat belt pre-
tensioners will activate.
● The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the right front passenger seat. However, t he SRS front
airbags for the front passenger may deploy if luggage is put in the seat,
even if the seat is unoccupied. ( P. 53)
■ SRS airbag deployment conditions (SRS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the even t 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
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/ h]).
● The SRS curtain shield airbags will deploy in the event of vehi cle rollover.
● The SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.

501-1. For safe use
■Conditions under which the SRS ai rbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS curtain shield airbags may also d eploy if a
serious impact occurs to the underside of your vehicle. Some ex amples are
shown in the illustration.
The SRS curtain shield airbags may also deploy under the situation shown in
the illustration.
■ Types of collisions that may not deploy the SRS airbags (SRS fr ont air-
bags)
The SRS front airbags do not generally inflate if the vehicle i s 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 suffici ent forward
deceleration of the vehicle, deployment of the SRS front airbag s may occur.
●
Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or vehicle 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

Operation of each component
■If you lose your keys
Type A and B
New genuine key can be made by your Toyota dealer using the other key and
the key number stamped on your key number plate.
Keep the plate in a safe place such as your wallet, not in the vehicle.
Type C
New genuine key can be made by your Toyota dealer.
The following are necessary when making new keys.
Mechanical key:
The key number for the mechanical key stamped on the number pla te and the
other key.
Key:
The key number for key stamped on the key number plate.
Keep the plates in a safe place such as your wallet, not in the vehicle.
There are key number plates for the mechanical key and key resp ectively.
When storing them, keep them in a safe place in a manner to dis tinguish one
from the other (such as markings, etc.).
■ When riding in an aircraft (type B or type C)
When bringing an wireless remote control function onto an aircr aft, make sure
you do not press any button on the key while inside the aircraf t 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.
■ Conditions affecting operation (type B or type C)
Type B
The wireless remote control function may not operate normally i n the following
situations.
● Near a TV tower, radio station, electric power plant, airport o r other facility
that generates strong radio waves
● When carrying a portable radio, cellular phone or other wireles s communi-
cation device
● When multiple wireless keys are in the vicinity
● When the wireless key has come into contact with, or is covered by a metal-
lic object
● When a wireless key (that emits radio waves) is being used near by
● When the wireless key has been left near an electrical applianc e such as a
personal computer
Type C
P. 142

1423-2. Opening, closing and locking the doors
■Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and en gine immobi-
lizer system from operating properly. (Ways of coping: P. 523)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by th e 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
● When the electronic key is placed near a battery charger or ele ctronic
devices
■ Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unl ocked.
• The electronic key is on the instrument panel or floor, or in the console
box or glove box when the engine is started or engine switch mo des are
changed.
