●When all of the following conditions are
met, the high beam will be automatically turned on (after approximately 1 second):• Vehicle speed is above approximately 40
km/h (25 mph). • The area ahead of the vehicle is dark.• There are no vehicles ahead with head-
lights or tail lights turned on. • There are few streetlights on the road ahead.
●If any of the following conditions are met, the high beam will be automatically
turned off: • Vehicle speed drops below approxi-mately 30 km/h (19 mph).
• The area ahead of the vehicle is not dark. • Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■Camera sensor detection information
●The high beam may not be automatically turned off in the following situations:• When oncoming vehicles suddenly
appear from a curve • When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road divid-ers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
●The high beam may be turned off if a
vehicle ahead that is using fog lights with- out using the headlights is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beam to switch to the low
beams, or the low beams to remain on.
●The following factors may affect the
amount of time taken to turn the high beam on or off:• The brightness of headlights, fog lights,
and tail lights of vehicles ahead • The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side• When a vehicle ahead is a two-wheeled
vehicle • The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
●The high beam may be turned on or off when the driver does not expect it.
●Bicycles or similar objects may not be detected.
●In the situations shown below, the system may not be able to accurately detect sur-
rounding brightness levels. This may cause the low beams to remain on or the high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In these cases, manually switch between the high and low beams.
• In bad weather (rain, snow, fog, sand- storms etc.)• The windshield is obscured by fog, mist,
ice, dirt etc. • The windshield is cracked or damaged.• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, changing color, or have improperly
adjusted aim. • When driving through an area of inter-mittently changing brightness and dark-

4-5. Using the driving support systems
*: If equipped
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the multi-
information display to urge the driver
to take evasive action.
■Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension sys-
tem ( P.262) will control the damping
force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.
■Steering control (if equipped)
When the system determines that the
possibility of a frontal collision is high
PCS (Pre-Collision System)*
The pre-collision system uses a
radar sensor and camera sensor to
detect vehicles and pedestrians*1 in
front of your vehicle. When the sys-
tem determines that the possibility
of a frontal collision with a vehicle
or pedestrian is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.212)
*1: Depending on the region in which
the vehicle was sold, the pedestrian
detection function may not be avail-
able. Contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer for details.
