With the headlights on, push
the lever away from you to turn
on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams with the headlights on or off.
■Daytime running light system
●Vehicles with halogen daytime running lights:
To make your vehicle more visible to other drivers, the headlight high beams
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.
Vehicles with LED daytime running lights:
To make your vehicle more visible to other drivers, the parking lights turn on
automatically (at an increased intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
U.S.A.: Daytime running lights can be turned off by operating the switch.
● 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.

The sensor may not function properly if an
object is placed on the sensor, or anything
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.

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 drivi ng 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
necessary, the system applies the brakes. A warning tone warns you when
the system cannot decelerate sufficiently to prevent your vehicle from clos-
ing in on the vehicle ahead.

WARNING
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclers, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to expressways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When an approach warning buzzer is heard often
● During emergency towing
■ When the sensor may not be correct ly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 193) will not be activated, which may lead to an
accident resulting in death or serious injury.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board etc.)

WARNING
●Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
■ Conditions under which the vehicle -to-vehicle distance control mode
may not function correctly
Operate the brake pedal (or accelerator pedal operation depending on the
situation) as necessary in the follow ing conditions as the radar sensor may
not be able to correctly detect vehicles ahead, which may lead to an acci-
dent resulting in death or serious injury.
● When the vehicle ahead of you decelerates suddenly
●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

◆Pre-collision warning
When a high possibility of a
frontal collision is detected, a
buzzer sounds and a message
is shown on the multi-informa-
tion display to urge the driver to
take evasive action.
◆Pre-collision brake assist
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.
◆Pre-collision braking
When there is a high po ssibility of a frontal collision, the system
warns the driver using warning display and buzzer. If the system
determines that a collis ion is unavoidable, the brakes are automati-
cally applied to reduc e the collision speed.
PCS (Pre-Collision System)
: If equipped
When the radar sensor detects pos sibility of a frontal collision,
brakes are automatically engaged to lessen impact as well as
vehicle damage.
The alert timing for the pre-co llision system can be changed or
turned on/off, as necessary, by operating the switch. (P. 222)

■The pre-collision system is operational when
The pre-collision system is on ( P. 222) and the following conditions are met:
● Pre-collision warning:
• Vehicle speed is greater than approximately 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 7 mph (10 km/h).
● Pre-collision brake assist:
• The VSC is not turned off.
• Vehicle speed is greater than approximately 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 19 mph (30 km/h).
• The brake pedal is depressed.
● Pre-collision braking:
• The VSC is not turned off.
• Vehicle speed is greater than approximately 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 7 mph (10 km/h).
■ Conditions that may trigger the system even if there is no possibility of a
collision
If the following obstructs the front of the sensor, the system judges that a col-
lision may be possible and operates.
●When passing by a vehicle while making left or right turns or passing a vehi-
cle in an opposite lane.
● When the vehicle rapidly approaches an object in front of it (such as another
vehicle, toll gate, etc.)
● When climbing a steep hill, etc., and ther e are structures in the upper region
of the road (billboards, low ceilings, street lamps, etc.)
● When driving through narrow passages or places with low ceilings (bridges,
tunnels, overhead passes, etc.)
● When driving on an uneven road surface
● When metal objects are on the road surface causing level differences or
protrusions in the road
● When an extreme change in vehicle height occurs
● When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact.
● When there is an obstacle on the side of an entrance of a curb for road
(guardrails, etc.)
When the system is activated in the situations described above, there is also
a possibility that the brakes will be applied with a force greater than normal.

Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
■ Situations in which the pre-collis ion system does not function properly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an intersec-
tion
● If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding with the VSC system off
● When an extreme change in vehicle height occurs
● When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact
● Due to greatly turning the wheel when an obstacle suddenly appears ahead
■ Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■ When there is a malfunction in the system, or if the system is tempo-
rarily unavailable
The PCS warning light flashes and a warning message is shown on the multi-
information display. If a warning message is shown on the multi-information
display, read the message and follow the instructions. ( P. 447, 460)
■ When the TRAC and VSC are turned off
●When the TRAC and VSC operations are turned off ( P. 218), the pre-colli-
sion brake assist and pre-collision braking are also turned off. However, the
alert function operates.
● The PCS warning light turns on and a warning message is shown on the
multi-information display. ( P. 447, 464)

WARNING
■Limitations of the pre-collision system
It is the driver’s responsibility to drive safely. The driver should be aware of
the surroundings and strive for safe driving.
Do not rely on the pre-collision system instead of normal braking opera-
tions. This system does not avoid or reduce collisions in every situation.
Overly relying on the system and entrusting it with safety may cause an
unexpected accident which could lead to death or serious injury.
Although the system is designed for the purpose to support in evading colli-
sions or reducing the damage of a collision, the effect changes according to
various conditions. ( P. 223) Therefore, it does not always provide the
same performance. Also, the pre-collision braking does not work depending
on the operating conditions of the driver. When the driver has stepped on
the brake pedal and is operating the steering wheel, the system judges that
the driver is taking evasive action and the automatic braking may not oper-
ate.
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an
accident.
● Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may not work
normally or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your
Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● If the radar sensor needs to be replaced, contact your Toyota dealer.
