NX300h_U_OM78007U ■
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 the instrument panel, luggage room, 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 the door will become lockable from the
outside, possibly trapping the el ectronic key inside the vehicle.●
As long as the electronic key is within the effective range, the doors may be locked or
unlocked by anyone. ●
Even if the electronic key is not inside the ve hicle, 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 door 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 approximately 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 door 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 th is, 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. 1 4 2 )●
If the electronic key is insi de 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.

144 3-2. Opening, closing and locking the doors
NX300h_U_OM78007U ●
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 6 ft. (2 m) of the
vehicle. ●
The smart access system with push-butto n start can be deactivated in advance.

Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre- collision system is in tended 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 limited range. It is not a mechanism that allows careless or inatten-
tive driving, and it is not a system that can assist the driver in low-visibility conditions. It
is still necessary for the driver to pay cl ose attention to the vehicle’s surroundings.●
Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data available to
the pre-collision system is that from obstacle s it has detected dire ctly in front of the
vehicle. Therefore, it is absolutely necess ary for the driver to remain vigilant and to
determine whether or not there is a possib ility of collision in any given situation.●
Assisting the driver in taking action
The pre-collision system’s braking assist feat ure is designed to help reduce the sever-
ity of a collision, and so only acts when the system has judged that a collision is
unavoidable. This system by itself, without the proper operations of the driver, is not
capable of automatically avoiding a collision or bringing the vehicle to a stop safely.
For this reason, when encountering a dangerous situation the driver must take direct
and immediate action in order to en sure the safety of all involved.

If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. Place the key in a position 6 ft. (2 m) 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 insi de the vehicle and a door handle becomes wet during a car
wash, a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors. ●
Set the electronic key to battery-saving mo de to disable the smart access system with
push-button start. (  P. 1 4 1 )■

When trouble arises
NX300h_U_OM78007U Start the engine of the second vehicle. Increase the engine speed slightly and
maintain at that level for approximately 5 minutes to recharge the 12-volt bat-
tery of your vehicle.
Open and close any of the doors of your vehicle with the power switch off.
Maintain the engine speed of the second vehicle and start the hybrid system
of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator light does not
come on, contact your Lexus dealer.
Once the hybrid system has started, remove the jumper cables in the exact
reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the fuse box
cover to its original position.
Once the hybrid system starts, have th e vehicle inspected at your Lexus dealer
as soon as possible. ■
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting. ■
To prevent 12-volt battery discharge ●
Turn off the headlights and the audio system while the hybrid system is off. ●
Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic. ■
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.) ■
When the 12-volt battery is removed or discharged ●
In some cases, it may not be possible to unlock the doors using the smart access system
with push-button start when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors. ●
The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.●
The power switch mode is memorized by the vehicle. When the 12-volt battery is
reconnected, the system will return to the mode it was in before the 12-volt battery was
discharged. Before disconnecting the 12-volt battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis-
charged, be especially careful when reconnecting the 12-volt battery. ●
The power back door must be initialized. (  P. 1 3 4 )●
Make sure that the key is not inside the vehicle when recharging or replacing the
12-volt battery. The key may be locked in the vehicle if the alarm is activated. (  P. 88)5
