■Note for locking the doors (vehicles with entry function)
●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 effective
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 vehicle.(Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry & start system. ( →P. 1 3 3 )
●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 display 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, or use the lock sensor
on the lower part of the door handle.
●Fingernails may scrape against the door during operation of the door handle. Be
careful not to injure fingernails or damage the surface of the door.
■Note for the unlocking function (vehicles with entry function)
●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 original position
and check that the doors unlock before pulling the door handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
●If the door handle becomes wet while the electronic key is within the effective
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 vehicle.
(Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry & start system. ( →P. 1 3 3 )
●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.
●Fingernails may scrape against the door during operation of the door handle. Be
careful not to injure fingernails or damage the surface of the door.

Operation of each component
GS350_250_OM_OM30E16E_(EE)
■Note for the push-start function
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly when the electronic key is on the instrument
panel, rear package tray or floor, or in the door pockets or glove box when the
engine is started or engine switch modes are changed.
●Even if the electronic key is not inside the vehicle, it may be possible to start the
engine if the electronic key is near the window.
■When the vehicle is not driven for extended periods
●Vehicles with entry function: To prevent theft of the vehicle, do not leave the elec-
tronic key within 2 m (6 ft.) of the vehicle.
●The smart entry & start system can be deactivated in advance. (→P. 6 5 0 )
■Alarm (if equipped)
Using the smart entry & start system to lock the doors will set the alarm system.
(→ P. 8 6 )
■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.
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 oper-
ate.)
●Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on the loca-
tion of the key (close to a spare tire [if equipped], the inside edge of the luggage
compartment), conditions (inside a metal bag, close to metallic objects) and the
radio waves in the surrounding area. ( →P. 1 7 7 )
■If the smart entry & start system does not operate properly
●Locking and unlocking the doors and opening the trunk: Use the mechanical key.

●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery becomes low, an alarm will sound in the cabin when the engine stops.
(→ P. 5 74 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when neces-
sary. ( →P. 4 8 9 )
• The smart entry & start system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) of
the following electrical appliances that produce a magnetic field:
•TVs

• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers

■Trunk light
The trunk light turns on when the trunk is opened.
■When closing the trunk
■Trunk easy closer (vehicles with power trunk lid)
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 locked 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 electronic 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 the places and the surrounding radio wave
conditions. In this case, the key confinement prevention function cannot be acti-
vated, causing the doors to lock when the 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.
Using the trunk grip, lower the trunk without
applying force to the side and push the trunk
down from the outside to close it.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety 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-crash safety system is only able to detect obstacles directly in front of the
vehicle, and only within a limited 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-crash safety system is that from obstacles 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 situation.
●Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce
the severity of a collision, and so only acts when the system has judged that a col-
lision is unavoidable. This system by itself is not capable of automatically avoiding
a collision or bringing the vehicle to a stop safely. For this reason, when encoun-
tering 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 dampened 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.
