SRS airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. As
the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the
occupants.Front passenger airbag

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. Daytime running lights are not designed for use at night.
Headlight control sensor
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction

2-3. Operating the lights and windshield wipers
CT200h_OM_OM76067E_(EE)
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 ACCES-
SORY 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 and the driver’s door is opened.
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
or position.
Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the num-
ber 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.
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 667)
NOTICE
To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is
off.

Rain-sensing windshield wipers (if equipped)
When “AUTO” is selected, the wipers will operate automati-
cally when the sensor detects falling rain. The system automati-
cally adjusts wiper timing in accordance with rain volume and
vehicle speed.
When “AUTO” is selected, the sensor sensitivity can be adjusted
as follows by turning the switch ring:
Rain-sensing wiper opera-
tion
Low speed wiper operation
High speed wiper opera-
tion
Temporary operation

When driving

Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper switch is turned to the “AUTO” position while the
“POWER” switch is in ON mode, the wipers will operate once to show
that AUTO mode is activated.
If the temperature of the raindrop sensor is 90 C (194 F) or higher, or -
15 C (5 F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
washer fluid tank.
CAUTION
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.
The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from
the rising or setting of the sun intermit-
tently strikes the windshield, or if bugs
etc. are present on the windshield.

2-4. Using other driving systems
CT200h_OM_OM76067E_(EE)
Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehi-
cles up to approximately 120 m (400 ft.) ahead, determines the cur-
rent vehicle-to-vehicle following distance, and operates to
maintain a suitable following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on
long downhill slopes.

When driving
CT200h_OM_OM76067E_(EE)
Dynamic radar cruise control can be set when
The shift position is in D.
Vehicle speed is above approximately 50 km/h (30 mph).
Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
Set speed
The set speed may be unsustainable depending on driving circumstances.
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
The sensor cannot operate correctly because it is covered in some way.
The windshield wipers are operating at high speed (when the wiper
switch is set to the “AUTO” mode or the high speed wiper operation
position).
If vehicle-to-vehicle distance control driving is automatically canceled for
any other reason, there may be a malfunction in the system. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

266
2-4. Using other driving systems
CT200h_OM_OM76067E_(EE)
Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following
situations:
Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
Vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving.
