2017 TOYOTA AURIS light sensor

2704-5. Toyota Safety Sense
UK AURIS_HB_EE (OM12K97E)■If the PCS warning light flashes or illuminates and a warning message is
displayed on the multi-information display
The pre-crash safety system may be temporarily unavailable or there may be
a malfunction in the system.
●In the following situations, the warning light will turn off, the message will
disappear and the system will become operational when normal operating
conditions return:
• When the area around the front sensor is hot, such as in the sun
• When the windshield is fogged up or covered with condensation or ice
(P. 406, 413)
• When the front sensor or the area around either sensor is cold, such as in
an extremely cold environment
• If the area in front of the front sensor is obstructed, such as when the
hood is open
●If the PCS warning light continues to flash or illuminate or the warning mes-
sage does not disappear, the system may be malfunctioning. Have the vehi-
cle inspected by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.
■If VSC is disabled
●If TRC and VSC are disabled (P. 334), the pre-crash safety brake assist
and pre-crash safety braking functions are also disabled. However, the pre-
crash safety warning function will still operate.
●The PCS warning light illuminates and “Pre-Crash Brake is disabled due to
VSC OFF.” is displayed on the multi-information display.

Push the lever away from you with
the headlight switch in
position.
The Automatic High Beam indica-
tor will come on when the head-
lights are turned on automatically
to indicate that the system is
active.
: If equipped
Automatic High Beam
The Automatic High Beam uses an in-vehicle front sensor to
assess the brightness of streetlights, the lights of vehicles
ahead etc., and automatically turns the high beam on or off as
necessary.
WARNING
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning the high beam on or off manually if
necessary.
■To prevent incorrect operation of the Automatic High Beam system
Do not overload the vehicle.

■High beam automatic turning on or off conditions
●When all of the following conditions are fulfilled, the high beam will be auto-
matically turned on (after approximately 1 second):
• Vehicle speed is approximately 40 km/h (25 mph) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
●If any of the following conditions is met, the high beams will turn off automat-
ically:
• Vehicle speed is below approximately 30 km/h (19 mph).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■Front sensor detection information
●The high beam may not be automatically turned off in the following situa-
tions:
• 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 beam may be turned off if a vehicle ahead that is using fog lights
without 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 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 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 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 front sensor is deformed or dirty.
• The front sensor temperature is extremely high.
• 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, are changing color, or are not aimed properly.
• 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, or are not aimed properly.
• The vehicle is listing or titling due to a flat tire, a trailer being towed, etc.

UK AURIS_HB_EE (OM12K97E)■Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this does not indicate a
malfunction.
●The front sensor is misaligned due to a strong impact being applied to the
sensor, etc.
●Dirt, snow, stickers, etc., are on the windshield near the front sensor.
●In inclement weather such as heavy rain, fog, snow or sand storms
●Light from an oncoming vehicle, the sun, etc., enters the front sensor.
●The sign is small, dirty, faded, tilted or bent, and if an electronic sign, the
contrast is poor.
●All or part of the sign is hidden by the leaves of a tree, a pole, etc.
●The sign is only visible to the front sensor for a short amount of time.
●The driving scene (turning, lane change, etc.) is judged incorrectly.
●Even if it is a sign not appropriate for the currently traveled lane, such a sign
exists directly after a freeway branches, or in an adjacent lane just before
merging.
●Stickers are attached to the rear of the preceding vehicle.
●A sign resembling a system compatible sign is recognized.
●The vehicle is driven in a country with a different direction of traffic.
●Side road speed signs may be detected and displayed (if positioned in sight
of the front sensor) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front sensor) while traveling on a roundabout.
●The speed information displayed on the meter and that displayed on the
Navigation system (if equipped) may be different due to the Navigation sys-
tem using map data.

■Sensor detection information
●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.
• A sensor is frozen.
• A 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 ultra-

In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
