Before driving
RX350/270_EE
■Notes for locking 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 effective
range, the door may lock and unlock repeatedly. Place the key in a position 2 m
(6 ft.) or more separate from the vehicle while the vehicle is being washed. (Take
care to ensure that the key is not stolen.)
●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.
■Notes for the unlocking function
●Gripping the door handle when wearing a glove may not unlock the door.
●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.
●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. 622)
■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 operate.)
