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.

4-5. 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.

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.

WARNING
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys- tem is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead to an accident.
■When the TRC/VSC/ABS is acti-vated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicle stability and dr iving force, do not turn the TRC/VSC systems off unless
necessary.
■Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision Brake. This system is designed to help reduce the possibility of further damage due to a secondary collision,
however, that effect changes according to various conditions. Overly relying on the system may result in death or serious
injury.
■Replacing tires
Make sure that all tires are of the speci-
fied size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRC and VSC systems will not
function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a
system to malfunction.
