Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed fo r more than a certain period of time
●When the shift lever is shifted to a position other than D
■To protect the automatic transmission
“Transmission Fluid Temp High See Owner’s Manual” is displayed on the multi-informa-
tion display and a function is adopted that automatically selects a higher shift range when
the fluid temperature is high. Have the vehicle inspected by your Lexus dealer.
■Downshifting restriction warning buzzer

be restricted. In some circum stances, downshifting may not be possible even when the
shift lever or paddle shif t switch is operated. (A buzzer will sound twice.)

will be displayed on the multi-information disp lay. (The display changes according to the
shift lever position and driving conditions.)
■When driving with dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because dy namic radar cruise control will not be can-
celed.
●8-speed models: While driving in the D posi tion, downshifting to 7, 6, 5 or 4.
( → P. 236)
●6-speed models: While driving in the D position, downshifting to 5 or 4.

includes M) with the accelerator pedal depressed, a warning message appears on
the multi-information display. ( →P. 527)
• When the accelerator pedal is depressed t oo much while the vehicle is in reverse.

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) secures 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.
■Deactivating AFS
Settings can be changed from on the multi-information display
(→ P. 84).
The indicator turns on when the AFS
is deactivated.

◆Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message 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 po ssibility of a frontal collision is high,
the system warns the driver. If the syst em determines that the possibility of a
frontal collision is extremely high, the br akes are automatically applied to help
avoid the collision or reduce the collision speed.
◆Suspension control (if equipped)
When the system determines that the po ssibility of a frontal collision is high,
the Adaptive Variable Suspension System ( →P. 290) will control the damping
force of the shock absorbers to help ma intain an appropriate vehicle posture.

the system will become operational when normal operating conditions return:
• When the radar sensor or ca mera sensor or the area around either sensor is hot,
such as in the sun
• When the radar sensor or camera sensor or the area around either sensor is cold,
such as in an extremely cold environment
• When the radar sensor or front grille embl em is dirty or covered with snow, etc.
• When the part of the windshield in front of the camera sensor is fogged up or cov-
ered with condensation or ice (Defogging the windshield:
→P. 406)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not disappear,
the system may be malfunctioning. Have the vehicle inspected by your Lexus dealer
immediately.
■If VSC is disabled

When driving on highways and freeways with white (yellow) lines, this function
alerts the driver when the vehicle might depart from its lane and provides assis-
tance by operating the steering whee l to keep the vehicle in its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the front
windshield.
◆Lane departure alert function
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver.
When the warning buzzer sounds or
the steering wheel vibrates, check
the surrounding road situation and
carefully operate the steering wheel
to move the vehicle back to the cen-
ter of the lane.

If the system detects that the steering
wheel has not been operated for a
fixed amount of time or the steering
wheel is not being firmly gripped, a
