Daytime running light system
To make your vehicle more visible to other drivers, the front position lights
turn on automatically 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 headlights turn off automatically if the
power switch is turned to ACCESSORY mode or turned off.
When the light switch is in : The headlights and all lights turn off auto-
matically if the power switch is turned to ACCESSORY mode or turned 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 or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.
Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCES-
SORY mode and the driver’s door is opened while the lights are turned on.
Automatic headlight leveling system
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. 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 system
to malfunction.

GS450h_300h_OM_OM30D53E_(EE)
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 120 m (400 ft.) ahead, determines the current
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.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes. A warning tone warns you when the
system cannot decelerate sufficiently to prevent your vehicle from closing
in on the vehicle ahead.

CAUTION
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 308) will not be activated, and a fatal or serious
accident may result.
Vehicles that cut in suddenly
Vehicles traveling at low speeds
Vehicles that are not moving
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Conditions under which the vehicle-to-vehicle distance control may not
function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
When water or snow thrown up by a the surrounding vehicles hinders the
functioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the
trunk etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly

Example of deceleration cruising and follow-up cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes. The system will respond to changes
in the speed of the vehicle ahead in order to maintain the vehicle-to-vehi-
cle distance set by the driver. A warning tone warns you when the system
cannot decelerate sufficiently to prevent your vehicle from closing in on
the vehicle ahead. When the vehicle ahead of you stops, your vehicle will
also stop. After the vehicle ahead starts off, pushing the cruise control

Dynamic radar cruise control with full-speed range can be set when
The shift lever is in D or range 4 or higher of S has been selected.
Range 4 or higher of D has been selected by using the paddle shift.
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.
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) when
there are no vehicle ahead.
The preceding vehicle leaves the lane when your vehicle is following at a
speed below 40 km/h (25 mph).
VSC is activated.
TRC is activated for a period of time.
When the VSC or TRC system is turned off by pressing the VSC OFF
switch.
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 AUTO mode or the high speed wiper operation).
When snow mode is set.
The parking brake is operated.
The vehicle is stopped by system control on a steep incline.
Pre-crash brake assist is activated.
The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The trunk or hood is opened.
• The vehicle has been stopped for about 3 minutes.
If vehicle-to-vehicle distance control driving is automatically canceled for
any other reason, there may be a malfunction in the system. Contact any
