The system may be malfunctio ning. Have the vehicle inspected by your Lexus dealer
immediately.
■If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the power switch with
the shift lever in P and the brake pedal depressed, contact your Lexus dealer imme-
diately.
■If the hybrid system is malfunctioning
 P. 5 0 3
■If the electronic key battery is depleted
P. 4 7 2
■If the smart access system with push-but ton start has been deactivated in a cus-
tomized setting
 P. 5 2 4
CAUTION
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If hybrid system 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 circumstance may lead to an accident, resulting in death or serious
injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle,
press and hold the power switch for more th an 2 seconds, or press it briefly 3 times
or more in succession. ( P. 485)
However, do not touch the power switch while driving except in an emergency.
Turning the hybrid system off while driving will not cause loss of steering or braking
control, however, power assist to the steering will be lost. This will make it more dif-
ficult to steer smoothly, so you should pull over and stop the vehicle as soon as it is
safe to do so.

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 inter-
sections 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 controlled by steering input.
AFS operates at speeds of 6 mph (10 km/h) or higher.

CAUTION
■When the sensor may not be correctly detecting a vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning ( P. 264) will not be activated, and a fatal or serious accident
may result.
●Vehicles traveling at low speeds
●Vehicles that are stationary
●Motorcycles traveling in the same lane
●Vehicles with small rear ends (trailers with no load on board etc.)
●Vehicles that cut in suddenly
Details about other people/objects the system will not detect:
 P. 2 6 9
■Conditions under which the vehicle-to-veh icle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
●When water or snow splashed by the su rrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is tilted upwards (due to a heavy load in the trunk etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead decelerates suddenly as the system is not able to
respond to sudden braking.

Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping, indi cations on the multi-information dis-
play, and a sensory warning* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the
center of the lane.
Lane keeping assist function• This function will be active when the vehicle-to -vehicle distance con-
trol mode of the dynamic radar crui se control with full-speed range
(  P. 257) is set with vehicle sp eed above approximately 45 mph
(72 km/h) and while the lane depa rture warning function is active.
• When the lane keeping assist fu nction is active, a slight steering
torque will be applied, to help the driver maintain the vehicle inside
the lane.
The lane keeping assist function will be temporarily canceled if the steering
wheel is not operated, or if you continue driving with your hands lightly touch-
ing the steering wheel. ( P. 2 7 8 )

after it has been activated, even if the vehicle leaves the lane again.
■The lane departure warning
It may be difficult to feel the sensory warning depending on the road conditions.
■No-handed driving warning
If the steering wheel is not operated for approximately 15 seconds on a straight road
or approximately 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will be tem-
porarily canceled. If you drive the vehicle with your hands lightly touching the steer-
ing wheel, this may also be detected as no-handed driving.

2804-5. Using the driving support systems
LS600hL_U(OM50E41U)
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving with a strong crosswind
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the driver
of the need for caution while driving. ( P. 5 0 3 )
CAUTION
■Before using the LKA system
Do not rely solely on the LKA system. The LKA system does not drive the vehicle
automatically, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsi bility for understanding his/her surround-
ings, for operating the steering wheel to correct the driving line, and for driving
safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LKA by mistake
Switch the LKA off using the LKA switch when not in use.
