driving tips”. ( P.267)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be reduced, the windows may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there may be a layer of water between the tires and the road surface, preventing the
steering and brakes from operating prop- erly.
Driving the vehicle
The following procedures should be
observed to ensure safe driving:

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 . Turning
the engine 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.

WARNING
●LC500:Always apply the parking brake, shift the shift position to P, stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.If the vehicle is parked with the shift
position in P but the parking brake is not set, the vehicle may start to move, possibly leading to an accident.
LC500h:Always apply the parking brake, shift the shift position to P, stop the hybrid system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-nated.
If the vehicle is parked with the shift position in P but the parking brake is not set, the vehicle may start to move,
possibly leading to an accident.
●LC500: Do not touch the exhaust pipes while the engine is running or immediately after turning the engine
off. Doing so may cause burns.LC500h: Do not touch the exhaust
pipes while the “READY” indicator is illuminated or immediately after turn-ing the hybrid system off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine
off. Otherwise, if you accidentally move the shift lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheat- ing. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases
may collect and enter the vehicle, lead- ing to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.Braking distance increases when the
brakes are wet, and this may cause one side of the vehicle to brake differently than the other side. Also, the parking
brake may not securely hold the vehi- cle.
●If the electronically controlled brake system does not operate, do not follow
other vehicles closely and avoid hills or sharp turns that require braking.In this case, braking is still possible, but
the brake pedal should be depressed more firmly than usual. Also, the brak-ing distance will increase. Have your
brakes fixed immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the systems fails, the other(s) will still
operate. In this case, the brake pedal should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time while driving, as this may restrain the engine
output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the same time to hold the
vehicle on a hill.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in
either direction and hold it there for an extended period of time. Doing so may damage the power
steering motor.

performance and increase brake wear. Have the vehicle inspected by any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer immedi- ately if this occurs.
Brake Hold
The brake hold system keeps the
brakes applied when the vehicle is
stopped by depressing the brake
pedal. This system can be used
when in a traffic jam or waiting for a
traffic light to change.
This system keeps the brake
applied when the shift position is in
D, M or N with the system on and
the brake pedal has been
depressed to stop the vehicle. The
system releases the brake when the
accelerator pedal is depressed with
the shift position in D or M to allow
smooth start off.

play.
If any of the conditions above are detected
when the brake hold system is enabled, the system will turn off and the brake hold standby indicator light will go off. In addi-
tion, if any of the conditions are detected while the system is holding the brake, a warning buzzer will sound and a message
will be shown on the multi-information dis- play. The parking brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a period of about 3 minutes after the sys-
tem has started holding the brake, the parking brake will be set automatically. In this case, a warning buzzer sounds and a
message is shown on the multi-informa- tion display.
●To turn the system off while the system is holding the brake, firmly depress the
brake pedal and press the button again.
●The brake hold function may not hold the
vehicle when the vehicle is on a steep incline. In this situation, it may be neces-sary for the driver to apply the brakes. A
warning buzzer will sound and the multi- information display will inform the driver of this situation. ( P.378)
■When the parking brake is set automati-
cally while the system is holding the brakes
The parking brake will not be released auto- matically. Perform one of the following pro-cedures to release the parking brake and
confirm that the parking brake indicator light turns off. ( P.187)

4-5. Using the driving support systems
*: If equipped
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage 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
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension sys-
tem ( P.262) will control the damping
force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.
■Steering control (if equipped)
When the system determines that the
possibility of a frontal collision is high
PCS (Pre-Collision System)*
The pre-collision system uses a
radar sensor and camera sensor to
detect vehicles and pedestrians*1 in
front of your vehicle. When the sys-
tem determines that the possibility
of a frontal collision with a vehicle
or pedestrian is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.212)
*1: Depending on the region in which
the vehicle was sold, the pedestrian
detection function may not be avail-
able. Contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer for details.

4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle following
distance, and operates to maintain a suitable following distance from the vehicle
ahead.
Note that vehicle-to-vehicle distance will clos e in when traveling on long downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle distance
can also be set by operating the vehicle-to-vehicle distance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in ve hicle speed is necessary, the system applies
the brakes (the stop lights will come on at th is time). The system will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when the system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehi cle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the +/RES switch or depressing the
accelerator pedal will resume follow-up cruising.

Driving
• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch
is turned off once and turned to IGNI- TION ON mode again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding environment may affect the ability of the sensor to correctly detect
obstacles. Particular instances where this may occur are listed below.• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, or on grass. • The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor in the vicinity.• The sensor is splashed with water or
heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.
