■Trunk easy closer (vehicles with power trunk opener and closer)
In the event that the trunk lid is left slightly open, the trunk easy closer will automati-
cally close it to the fully closed position.
■Function to prevent the trunk being lo cked with the electronic key inside
●When all doors are being locked, closing the trunk lid with the electronic key left
inside the trunk will sound an alarm.
In this case, the trunk lid can be opened pressing the trunk release button on the
trunk lid.
●Even when the spare electronic key is put in the trunk with all the doors locked, the
key confinement prevention function can be activated so the trunk can be opened.
In order to prevent theft, take all electron ic keys with you when leaving the vehicle.
●Even when the electronic key is put in the trunk with all the doors are locked, the
key may not be detected depending on th e places and the surrounding radio wave
conditions. In this case, the key confinem ent prevention function cannot be acti-
vated, causing the doors to lock when th e trunk is closed. Make sure to check
where the key is before closing the trunk.
●The key confinement prevention function cannot be activated if any one of the
doors is unlocked. In this case, open the trunk using the trunk opener.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended to assist
the driver in avoiding collisions through the process of LOOK-JUDGE-ACT.
There are limits to the degree of assistance the system can provide, so please keep
in mind the following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the
vehicle, and only within a lim ited range. It is not a mechanism that allows careless
or inattentive driving, and it is not a system that can assist the driver in low-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
When attempting to estimate the possibility of a collision, the only data available
to the pre-collision system is that from ob stacles it has detected directly in front of
the vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant
and to determine whether or not there is a possibility of collision in any given situ-
ation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help reduce the
severity of a collision, and so only acts wh en the system has judged that a collision
is unavoidable. This system by itself is not capable of automatically avoiding a col-
lision or bringing the vehicle to a stop sa fely. For this reason, when encountering a
dangerous situation the driver must take direct and immediate action in order to
ensure the safety of all involved.
NOTICE
■Precautions for cleaning the driver monitor sensor
●Gently wipe the sensor with a soft cloth to prevent damage.
●Wipe any excess dirt with a cloth dampen ed with neutral detergent, all liquids
having been wringed out of the cloth. After that, wipe again with a dry cloth.
●Do not use benzene, thinner, glass cleaners, wax, etc.

When trouble arises
■When recharging or replacing the battery
●Make sure that the key is not inside the vehicle when recharging or replacing the
battery. The key may be locked in the vehicle if the alarm is activated. ( P. 7 3 )
●In some cases, it may not be possible to unlock the doors using the smart access
system with push-button start when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but
will start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was dis-
charged. Before disconnecting the ba ttery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prev ent accidentally igniting the flammable
gas that may be emi tted from the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
