1183-2. Opening, closing and locking the doors
Trunk
The trunk can be opened using
the trunk opener, entry func-
tion (if equipped) or wireless
remote control.
WA R N I N G
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■Before driving
●Make sure that the trunk lid is fully closed. If the trunk lid is not fully
closed, it may open unexpectedly
while driving and hit near-by objects or luggage in the trunk may be
thrown out, causing an accident.
●Do not allow children to play in the
trunk.
If a child is accidentally locked in the trunk, they could suffer from
heat exhaustion, suffocation or
other injuries.
●Do not allow a child to open or
close the trunk lid. Doing so may cause the trunk lid to
open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
■Important points while driving
Never let anyone sit in the trunk. In
the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of
the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid
before opening it. Failure to do so
may cause the trunk lid to suddenly shut again after it is opened.
●When opening or closing the trunk lid, 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 trunk is about to open or close.
●Use caution when opening or clos-ing the trunk lid in windy weather as
it may move abruptly in strong wind.
●The trunk lid may suddenly shut if it
is not opened fully. It is more diffi-
cult to open or close the trunk lid on an incline than on a level surface,
so beware of the trunk lid unexpect-
edly opening or closing by itself. Make sure that the trunk lid is fully
open and secure before using the
trunk.
●When closing the trunk lid, take
extra care to prevent your fingers etc. from being caught.

1243-2. Opening, closing and locking the doors
●Touching the door lock or unlock sen-
sor while wearing gloves may prevent lock or unlock operation.
●On some models: When the lock operation is performed using the lock
sensor, recognition signals will be
shown up to two consecutive times. After this, no recognition signals will
be given.
●If the door handle becomes wet while
the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow
the following correction procedures to
wash the vehicle: • Place the electronic key in a location 2
m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-sav-
ing mode to disable the smart entry & start system. ( P.122)
●If the electronic key is inside the vehi- cle 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 prop-
erly if it comes into contact with ice, snow, mud, etc. Clean the lock sensor
and attempt to operate it again.
●A sudden handle operation or a han-
dle operation immediately after enter-
ing the effective range may prevent the doors from being unlocked. Touch
the door unlock sensor and check that
the doors are unlocked 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.
■When the vehicle is not driven for
extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 2 m (6 ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance. ( P.538)
●Setting the electronic key to bat-
tery-saving mode helps to reduce key battery depletion. ( P.122)
■To operate the system properly
●Make sure to carry the electronic key when operating th e system. Do not
get the electronic key too close to the
vehicle when operating the system from the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the
system may not operate properly. (The alarm may go off accidentally, or the
door lock prevention function may not
operate.)
●Do not leave the electronic key inside
the trunk. The key confinement prevention func-
tion may not operate, depending on
the location of the key (the inside edge of the trunk), conditions (inside a
metal bag, close to metallic objects)
and the radio waves in the surround- ing area. ( P.120)
■If the smart entry & start system
does not operate properly
●Locking and unlocking the doors
(vehicles with entry function): P.512
●Starting the engine: P.512
