■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
●Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■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.

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 400 ft. (120 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able 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 automati-
cally decelerates your vehicle. When a greater reduction in vehicle speed
is necessary, 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 radar 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 alarm (
P. 220) 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 the surrounding vehicles hinders the
functioning of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment, 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

■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehi-
cle’s front corner and rear bumpers.
●Certain vehicle conditions and the surrounding environment may affect
the ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will
resolve this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show
an abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is
installed.
• People may not be detected if they are wearing certain types of cloth-
ing.
In addition to the examples above, there are instances in which, because
of their shape, signs and other objects may be judged by the sensor to be
closer than they are.

CAUTION
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction etc. Have the vehicle checked by your Toyota dealer.
●A beep does not sound when you turn the main switch on.
●The intuitive parking assist operation display flashes, and a beep sounds
when no obstacles are detected.
●If the area around a sensor collides with something, or is subjected to
strong impact.
●If the bumper collides with something.
●If the display shows continuously without a beep.
●If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

Pre-Collision System
: If equipped
When a frontal collision seems likely, the system attempts to lessen
vehicle’s damage. Two types of pre-collision system are available.
The brake-linked pre-collision system operates in conjunction with
the braking operation of the driver. The radar type pre-collision sys-
tem has a sensor that is used to detect an unavoidable frontal colli-
sion.
■Pre-collision seat belts (front seats only)
Brake-linked pre-collision system
Based on the speed and amount of the driver’s braking operation, the
system determines if emergency braking is being performed. If this
determination is made, the seat belts are immediately retracted to
increase the effectiveness of the pretensioners (P. 80). In addition,
the system also operates if the driver loses control of the vehicle.
Radar type pre-collision system
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 80)
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision brake assist (Radar type only)
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.

LC200_OM_OM60F57U_(U)
■Obstacles not detected (Radar type only)
The sensor cannot detect plastic obstacles such as pylons. There may also
be occasions when the radar sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■The pre-collision system is operational when
●Pre-collision seat belts (situation 1)
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (situation 2)
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision brake assist
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.

■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking several driving trips. If
the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■If the low speed four-wheel drive indicator light or the center differen-
tial lock indicator light blinks
Take the specified steps. (P. 243)
If the brake system warning light or the malfunction indicator light also
comes on, or the low speed four-wheel drive indicator light or the center dif-
ferential lock indicator light continues to blink after taking the specified steps,
there may be a malfunction in the engine, the brake system or the four-
wheel drive system. In this case, you may not be able to transfer between
“H4” and “L4” modes, and the center differential lock may not be able to be
locked or unlocked. Have the vehicle inspected by your Toyota dealer imme-
diately.
■Front passenger detection sensor and passenger seat belt reminder
●If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
