RX350_U_OM48E90U 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.
AFS (Adaptive Front-lighting System) secure s excellent visibility at intersections
and on curves by automatically adjusting the direction of the light axis of the
headlights according to vehicle speed and the degree of the tire’s angle as con-
trolled by steering input. AFS operates at speeds of 6 mph (10 km/h) or higher.
●
When the steering wheel or turn signal lever is operated while the headlights
are on (low beam), a cornering light w ill turn on and light up the direction of
movement of the vehicle. The cornerin g lights are designed to ensure excel-
lent visibility when making a turn at an intersection.However, when vehicle speed is approximately 22 mph (35 km/h) or higher, the cor-
nering lights will not turn on.●
When the shift lever is in R while the headlights are on (low beam), both cor-
nering lights will turn on. This is desi gned to enhance visibility when parking.Turning on the high beam headlights 1

Conditions to turn the high beams on/off automatically ●
When all of the following conditions are met, the high beams will be turned on automat-
ically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) 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 automatically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headli ghts or tail lights turned on.
• There are many streetlights on the road ahead. ■
Camera sensor dete ction information●
The high beams may not be automatically turned off in the fo llowing situations:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected du e to repeated curves, road dividers or
roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on ●
The high beams may be turned off if a vehicl e ahead that is using fog lights without its
headlights turned on is detected. ●
House lights, street lights, traffic signals, and illuminated billboards or signs and other
reflective objects may cause the high beams to change to the low beams, or the low
beams to remain on. ●
The following factors may affect the amount of time taken for the high beams to turn on
or off:
• The brightness of the headlights, fog li ghts, 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 in the vehicle ●
The high beams may turn on or off unexpectedly.●
Bicycles or similar vehicles may not be detected.

In the following situations the system may not be able to correctly detect the surround-
ing brightness level. This may cause the lo w beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (hea vy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equa l to that of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ah ead are turned off, dirty, changing color,
or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of intermit tently 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 roads, etc.)
•When frequently and repe atedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or mirror
• When the back of a preceding vehicle is hi ghly reflective, such as a container on a
truck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling pedestri-
ans or other drivers■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the engine switch to IGNITION ON mode.
Within 30 seconds after , re peat pulling the headlight sw itch lever to the original
position then pushing it to the high beam po sition quickly 10 times, then leave the lever
in high beam position.
If the sensitivity is changed, the Automatic High Beam indicator is turn on and off 3
times.
Automatic High Beam (headlights) may turn on even the vehicle is stopped.1

Lexus Safety System+
The Lexus Safety System+ 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 performance that
this system can provide, do not overly rely on this system. The driver is always responsi-
ble for paying attention to the vehicl e's surroundings and driving safely.
