CT200h_OM_OM76102E_(EE)
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 the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic 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 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 water splashes on the door handle,
such as in the rain or in a car wash when the electronic key is within the effec-
tive range. (The door will automatically be locked after approximately 30 sec-
onds if the doors are not opened and closed.)
If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by
the entry function. (Use the wireless remote control to unlock 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.

Daytime running light system
To make your vehicle more visible to other drivers, the front position lights turn
on automatically (at an increased intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed for
use at night.
Headlight control sensor
Automatic light off system
When the light switch is in the or position: The headlights turn off
automatically if the power switch is turned to ACCESSORY mode or OFF.
When the light switch is in the position: The headlights and all lights turn
off automatically if the power switch is turned to ACCESSORY mode or OFF.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to the

Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights
do not interfere with other road users.
Light reminder buzzer (if equipped)
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.

saving function will operate and automatically turn off all the lights after approx-
imately 20 minutes. When the power switch is turned to ON mode, the 12-volt
battery-saving function will be disabled.
When any of the following are performed, the 12-volt battery-saving function is

When the headlight switch is operated
When a door is opened or closed
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 650)

Caution regarding the use of windshield wipers in “AUTO” mode (vehicles
with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers
etc. do not become caught in the windshield wipers.
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE

Do not use the wipers, as they may damage the windshield.
When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may overheat.
When a nozzle becomes blocked
In this case, contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system is
off.
