AHS (Adaptive High-beam System)
●Adjusts the brightness and illuminated area of the high beams
according to the vehicle speed.
● Operates the variable high
beams so that the area around
vehicles ahead is partially not
illuminated while all other areas
continue to be illuminated with
the high beams.
The variable high beams help opti-
mize forward visibility while reduc-
ing the dazzling effect on the
drivers of vehicles ahead.
● Adjusts the intensity of the high beams, while driving on a curve, so
that the area in the direction that the vehicle is turning will be illumi-
nated more brightly than other areas.
● Adjusts the distance that the low beams are projected according to
the distance to a preceding vehicle.
The Adaptive High-beam System uses a camera sensor located
behind the upper portion of the windshield to assess the bright-
ness of the lights of vehicles ahead, streetlights, etc., and auto-
matically controls the headlight light distribution as necessary.

WARNING
■ Limitations of the Adaptive High-beam System
Do not rely on the Adaptive High-beam System. Always drive safely, taking
care to observe your surroundings and turning the high beam on or off man-
ually if necessary.
■ To prevent incorrect operation of the Adaptive High-beam system
Do not overload the vehicle.

■Conditions in which the light distribution control of the headlights
changes automatically
●When all of the following conditions are met, the high beams will be turned
on automatically and the system will operate:
• The vehicle speed is approximately 15 km/h (9 mph) or more.
*
• There are no vehicles ahead with headlights or tail lights turned on.
• The area ahead of the vehicle is dark.
*: If the vehicle speed is approximately 30 km/h (19 mph) or more, the area in
the direction that the vehicle is turning will be illuminated more brightly than
other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will
turn on and the distance that the low beams are projected will be adjusted
automatically, depending on the location of vehicles ahead:
• The vehicle speed is approximately 15 km/h (9 mph) or more.
• There are vehicles ahead with headlights or tail lights turned on.
• The area ahead of the vehicle is dark.
●If any of the following conditions is met, the high beams or variable high
beams will be changed to the low beams automatically:
• The vehicle speed is below approximately 15 km/h (9 mph).
• The area ahead of the vehicle is not dark.
• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the
drivers of the other vehicles.
■Camera sensor detection information
●The high beams may not be automatically changed to the variable high
beams in the following situations:
• When vehicles ahead 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
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
●The high beams may be changed to the variable high beams if a vehicle
ahead that is using fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beams to change to the variable high beams, cause the
high beams not to change to the variable high beams, or change the area
that is not illuminated.

●The following factors may affect the amount of time taken to turn the high
beam on or off, or the speed by which the areas not illuminated change:
• 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 operational 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 light distribution control of the headlights may change unexpectedly.
●Bicycles or similar objects may not be detected.
●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low beams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or have are not aimed properly.
• The vehicle is hit by water, snow, dust, etc. from a preceding vehicle.
• When driving through an area of intermittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or
roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a
truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.

WARNING
■ Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that
the driver will drive safely, and is designed to help reduce the impact to the
occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

When starting the hybrid system next time, operate the hybrid system for
approximately 5 minutes to recharge the 12-volt battery.
■ If “Forward Camera System Unavailable” or “Forward Camera System
Unavailable Clean Windshield” is displayed.
The following systems may be suspended until the problem shown in the
message is resolved.
● PCS (Pre-Crash Safety system)
● LDA (Lane Departure Alert with steering control)
● Dynamic radar cruise control with full-speed range
● AHS (Adaptive High-beam System)
■ If the shift position cannot be changed or the power switch is turned to
ACCESSORY mode even if trying to turn the power switch off when a
warning message is shown
If the 12-volt battery is discharged or the shift control system is malfunction-
ing, the followings may occur.
● The shift position may not be changed to P.
When parking, stop the vehicle on level ground and apply the parking brake
firmly.
● The hybrid system may not start.
● The power switch may be turned to ACCESSORY mode even if trying to
turn the power switch off.
In this case, the power switch may be turned off after applying the parking
brake.
● The automatic P position selection function (P. 336) may not operate.
Before turning the power switch off, be sure to press the P position switch
and check that the shift position is in P by the shift position indicator or P
