Operation of each component
RX450h_RX450hL _U_OM48F85U■
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 near the ground or in a high place, or too close to the rear
bumper center when the back door is opened.
• The electronic key is on th e instrument panel, luggage co mpartment, 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 th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outs ide the cabin and th e door will become lockable from the
outside, possibly trapping the electronic key inside the vehicle. ●
As long as the electronic key is within th e effective range, the doors may be locked or
unlocked 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 wa ter splashes on the d oor handle, 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 approx imately 60 seconds if the doors are not
opened and closed.) ●
If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.) ●
Touching the door lock sensor while wearin g gloves may delay or prevent lock opera-
tion. Remove the gloves and touch the lock sensor again. ●
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 el ectronic 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 6 ft. (2 m) 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 access system
with push-button start. ( → P. 160)●
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 mult i-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. ●
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 de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.
