WA R N I N G
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and hold
the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( P. 4 6 9 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
NOTICE
■To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode for long
periods of time without the engine running.
●If “POWER ON” is displayed on the multi- information display, the engine switch is
not off. Exit the vehicle after turning the engine switch off.
●Do not stop the engine when the shift lever is in a position other than P. If the engine is
stopped in another shift lever position, the engine switch will not be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY
mode, battery discharge may occur.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehicle checked
by your Lexus dealer immediately.
■Symptoms indicating a malfun ction with the engine switch
If the engine switch seems to be operating somewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

ES350_OM_OM33B64U_(U)4-3. Operating the lights and wipers
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) impr
oves visibility at intersections and on
curves by automatically adjusting the lateral angle of the headlights according to
vehicle speed and the degree of the tire angle that are controlled by steering
input.
Operates at speed of 6 mph (10 km/h) or higher.
■Deactivating AFS
Select “AFS” on (settings display) of the multi-information display.
( P. 7 9 )
Press the meter control switch.
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenever the engine is started and the parking
brake is released. (Illuminate brighter than the parking lights.) Daytime running lights
are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor

AFS (Adaptive Front-lighting System) (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

The Lexus Safety System+ consists of the following drive assist systems and
contributes to a safe and comfo rtable driving experience:
WA R N I N G
■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.

■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collision system instea d of normal braking operations under any
circumstances. This system will not preven t collisions or lessen collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to
an accident, resulting in death or serious injury.
●Although this system is design ed to help avoid and reduce the impact of a collision, its
effectiveness may change according to various conditions, therefore the system may
not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may operat e even if there is no possibility of a
collision: P. 1 9 0
• Conditions under which the syst em may not operate properly: P. 1 9 3
●Do not attempt to test the operation of the pre-collision system yourself, as the system
may not operate properly, possibly leading to an accident.
■Pre-collision braking*3
●The pre-collision braking function may not operate if certain operations are per-
formed by the driver. If the accelerator peda l is being depressed strongly or the steer-
ing wheel is being turned, the system may de termine that the driver is taking evasive
action and possibly prevent the pre-colli sion braking function from operating.
●In some situations, while the pre-collision braking function is operating, operation of
the function may be canceled if the accele rator pedal is depressed strongly or the
steering wheel is turned and the system determines that the driver is taking evasive
action.
●A large amount of braking force is applied while the pre-collision braking function is
operating. Additionally, as the vehicle may creep if it has been stopped by the pre-
collision braking function, the driver should depress the brake pedal as necessary.
●If the brake pedal is being depressed, the system may determine that the driver is tak-
ing evasive action and possibly delay the op eration timing of the pre-collision braking
function.
*3: Depending on the region in which the ve hicle was sold, the pre-collision braking
function may not be available.

■Pedestrian detection function*5
*5: Depending on the region in which the vehicle was sold, the pedestrian detection func-
tion may not be available.
■Cancelation of the pre-collision braking*3
●If either of the following occur while the pr e-collision braking function is operating, it
will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●If the vehicle is stopped by the operation of the pre-collision braking function, the oper-
ation of the pre-collision braking function will be canceled after the vehicle has been
stopped for approximately 2 seconds.
*3: Depending on the region in which the vehi cle was sold, the pre-collision braking func-
tion may not be available.
■Conditions under which the system may operate even if there is no possibility of a colli-
sion
●In some situations such as the following, th e system may determine that there is a possi-
bility of a frontal co llision and operate.
• When passing a vehicle or pedestrian
*5
• When changing lanes while overtaking a preceding vehicle
• When overtaking a preceding vehicle that is changing lanes
The pre-collision system detects pedestrians
based on the size, profile, and motion of a
detected object. However, a pedestrian may not
be detected depending on the surrounding
brightness and the motion, posture, and angle of
the detected object, preventing the system from
operating properly. (
P. 1 9 4 )
• When overtaking a preceding vehicle that is making a left/right turn
• When passing a vehicle in an oncoming lane that is stopped to make a right/left turn

ES350_OM_OM33B64U_(U)4-5. Using the driving support systems
LDA (Lane Departure Alert with steering control)
When driving on highways and freeways with white or yellow lines, this function
alerts the driver when the vehicle might depart from its lane and provides assis-
tance by operating the steering wheel to keep the vehicle in its lane.
The LDA system recognizes visible
white or 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 within the white (yellow) lines.

◆Steering control function
When the system determines that
the vehicle might depart from its
lane, the system provides assistance
as necessary by operating the steer-
ing wheel in small amounts for a
short period of time to keep the
vehicle in its 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
warning is displayed on the multi-
information display and the function
is temporarily canceled.
◆Ve h i c l e s w a y w a r n i n g
When the vehicle is swaying or
appears as if it may depart from its
lane multiple times, the warning
buzzer sounds and a message is dis-
played on the multi-information dis-
play to alert the driver.
