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.

1-4. Theft deterrent system
For safety and security
lowing: • Wind or the movement of objects such as leaves and insects inside the vehicle
• Ultrasonic waves emitted from devices such as the intrusion sensors of other vehicles
• The movement of people outside the vehicle
●Unstable items, such as dangling acces-sories or clothes hanging on the coat hooks, are in the vehicle.
●The vehicle is parked in a place where extreme vibrations or noises occur, such
as in a parking garage.
●Ice or snow is removed from the vehicle, causing the vehicle to receive repeated impacts or vibrations.
●The vehicle is inside an automatic or high-pressure car wash.
●The vehicle experiences impacts, such as hail, lightning strikes, and other kinds of repeated impacts or vibrations.
■Tilt sensor detection considerations
The sensor may trigger the alarm in the fol- lowing situations:
●The vehicle is transported by a ferry, trailer, train, etc.
●The vehicle is parked in a parking garage.
●The vehicle is inside a car wash that moves the vehicle.
●Any of the tires loses air pressure.
●The vehicle is jacked up.
●An earthquake occurs or the road caves in.
NOTICE
■To ensure the intrusion sensor func-tion correctly
●To ensure that the sensors operate properly, do not touch or cover them.

■If the PCS warning light flashes and a
warning message is displayed on the multi-information display
The pre-collision system may be temporar- ily unavailable or there may be a malfunc-
tion in the system. In this case, read the warning message and follow the instruction.
●In the following situations, the warning light will turn off, the message will disap-pear and the system will become opera-
tional when normal operating conditions return:• When the radar sensor or camera sensor
or the area around either sensor is hot, such as in the sun• When the radar sensor or camera sensor
or the area around either sensor is cold, such as in an extremely cold environment• When the radar sensor or front grille
emblem is dirty or covered with snow, etc.•When the part of the windshield in front
of the camera sensor is fogged up or cov- ered with condensation or ice (Defog-ging the windshield: P.281)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the cam-
era sensor
●If the PCS warning light continues to flash
or the warning message does not disap- pear, the system may be malfunctioning. Have the vehicle inspected by any autho-
rized Lexus retailer or Lexus authorized repairer, or any reliable repairer immedi-
ately.

4-5. Using the driving support systems
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.
