1-1. For safe use
●A frontal impact applied to the front bumper while driving at speeds outside of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situ-ations, the Pop Up Hood may operate.)
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever.
Doing so after the Pop Up Hood has operated will further raise the hood and may cause an injury. Do not drive
with the hood raised, as doing so may block the driver’s vision, possibly caus-ing an accident.
●Do not forcibly push down the hood.
As the popped up hood cannot be lowered by hand, doing so may deform the hood or cause an injury.
●If the Pop Up Hood has operated, have
it replaced by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. If the Pop Up
Hood has operated, stop the vehicle in a safe place and contact authorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lifters may be hot and burn you.
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate
properly if the hood is not fully closed.
●Make sure that all 4 tires are of the specified size and inflated to the speci-fied tire pressure. If tires of a different
size are used, the system may not operate properly.
●If something has hit the area around the front bumper, the sensors may be
damaged even if the Pop Up Hood has not operated. Have the vehicle inspected by any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing
so may cause accidental operation or prevent the system from operating properly. If repair or replacement is
necessary, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●Do not remove such components as
the front bumper, hood or suspension, or replace them with non-genuine parts, as doing so may prevent the sys-
tem from operating properly.
●Do not install anything to the front bumper or hood, as doing so may pre-vent the sensors from detecting an
impact correctly and prevent the sys- tem from operating properly.
●Do not close the hood with force or
apply load to the lifters, as doing so may damage the lifters and prevent the system from operating properly.
●Do not modify the suspension, as
changes made to the vehicle height may prevent the system from operat-ing properly.

4-1. Before driving
WARNING
■When starting the vehicle
LC500: Always keep your foot on the
brake pedal while stopped with the engine running. This prevents the vehicle from creeping.
LC500h: Always keep your foot on the brake pedal while stopped with the
“READY” indicator is illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelera-tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera-
tor pedal instead of the brake pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in
operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress
the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay
response in an emergency, resulting in an accident.
●LC500h: The driver should pay extra attention to pedestrians when the vehi-
cle is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians may mis-
judge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.The exhaust system and exhaust gases
can be extremely hot. These hot parts may cause a fire if there is any flamma-ble material nearby.
●During normal driving, do not turn off the engine <hybrid system>. Turning
the engine <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 difficult to steer smoothly, so you should pull over and
stop the vehicle as soon as it is safe to do so. In the event of an emergency, such as if
it becomes impossible to stop the vehi- cle in the normal way: P.360
●Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill. Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P.173, 179)
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear view mirrors while driv-
ing. Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not outside the vehicle.
■When driving on slippery road sur-
faces
●Sudden braking, acceleration and
steering may cause tire slippage and reduce your ability to control the vehi-cle.
●Sudden acceleration, engine braking
due to shifting, or changes in engine speed could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly
depress the brake pedal to make sure that the brakes are functioning prop-erly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one side are wet and not functioning properly, steering con-
trol may be affected.

4-1. Before driving
NOTICE
●When driving over bumps in the road, drive as slowly as possible to avoid damaging the wheels, underside of the
vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P.384)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the following serious damage to the vehi-
cle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure
to have any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer check the following:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis- sion, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to shift
the shift position to P, or from P to other positions. In this case, contact any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer immedi- ately.
■When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.

4-5. Using the driving support systems
Driving
and the driver is operating the steering
wheel, the LDH system ( P.263) will
control the turning angle of the front
and rear wheels and effort necessary
to turn the steering wheel to help
enhance steering responsiveness.
WARNING
■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 instead of normal braking operations under any circumstances. This system
will not prevent collisions or lessen col- lision damage or injury in every situa-tion. Do not overly rely on this system.
Failure to do so may lead to an acci- dent, resulting in death or serious injury.
●Although this system is designed to
help avoid a collision or help reduce the impact of the co llision, its effective- ness 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 care- fully. Do not overly rely on this system and always drive carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision: P.214
• Conditions under which the system
may not operate properly: P.215
●Do not attempt to test the operation of the pre-collision system yourself, as the system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of braking force will be applied.
●If the vehicle is stopped by the opera-tion of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after approximately 2seconds. Depress the
brake pedal as necessary.
●The pre-collision braking function may not operate if certain operations are performed by the driver. If the acceler-
ator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the
driver is taking evasive action and pos- sibly prevent the pre-collision braking function from operating.
●In some situations, while the pre-colli-
sion braking function is operating, operation of the function may be can-celed if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-mines that the driver is taking evasive
action.
●If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and pos- sibly delay the operation timing of the pre-collision braking function.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When transporting the vehicle via
truck, boat, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running <hybrid system
operating> and the tires are allowed to rotate freely

enabled/disabled on ( P.92) of
the multi-information display.
The system is automatically enabled each
time the engine switch <power switch> is
turned to IGNITION ON mode <ON
mode>.
If the system is disabled, the PCS warn-
ing light will turn on and a message will
be displayed on the multi-information
display.
■Changing the pre-collision warn-
ing timing

■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rap-idly from behind into a blind spot. Do not
overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to
an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
