WARNING

Observe the following precautions.
Failure to do so may result in death or serious injury.

■

Before driving

●

Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.

●

Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.

●

Do not allow a child to open or close the back door.
Doing so may cause the back door to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.

■

Important points while driving

●

Keep the back door closed while driving.
If the back door is left open, it may hit near-by objects or luggage in the
luggage compartment may be thrown out, causing an accident.

●

Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

288

WARNING

■

Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.

●

Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.

●

When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.

●

If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.

●

Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.

●

Do not pull on the back door damper stay to close the back door, and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.

●

If a bicycle carrier or similar heavy object is attached to the back door, it
may suddenly shut again after being opened, causing someone’s hands,
head or neck to be caught and injured. When installing an accessory part
to the back door, using a genuine Toyota part is recommended.

●

The back door may suddenly shut if it is
not  opened  fully.  It  is  more  difficult  to
open  or  close  the  back  door  on  an
incline  than  on  a  level  surface,  so
beware  of  the  back  door  unexpectedly
opening or closing by itself. Make sure
that  the  back  door  is  fully  open  and
secure  before  using  the  luggage  com-
partment.

●

When closing the back door, take extra
care to prevent your fingers etc. from
being caught.

●

When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.

Conditions affecting operation
The smart key system, wireless remote control and immobilizer system use
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 prop-
erly. (Ways of coping:

●

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 electrical
noise

●

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 other wireless key (that emit radio waves) is being used nearby

●

When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless commu-

nication devices

• 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
rear window

●

■

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 unlocked.

• The electronic key is on the instrument panel, floor, or in the door pockets

or glove box when the hybrid system is started or power switch modes
are changed.

●

Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.

●

As long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.

●

Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.

●

The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
60 seconds if the doors are not opened and closed.)

●

If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)

●

Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.

●

If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 6 ft. (2 m) or more away from the

vehicle. (Take care to ensure that the key is not stolen.)

• Set electronic key to battery-saving mode to disable the smart key sys-

tem. (

P. 292)

●

If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

●

The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.

●

A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.

●

If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

295

■

When the vehicle is not driven for extended periods

●

To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
(2 m) of the vehicle.

●

The smart key system can be deactivated in advance. (

P. 741)

■

To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.

may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention may not operate.)
