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
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
WARNING
■Before using LKA system
Do not rely solely upon the LKA system. The LKA system does not automatically
drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must
always assume full responsibility for driv- ing safely by paying careful attention to the surrounding conditions and operat-
ing the steering wheel to correct the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time. Failure to perform appropriate driving operations and pay careful attention may
lead to an accident, resulting in death or serious injury.
■To avoid operating LKA system by mistake
When not using the LKA system, use the LKA switch to turn the system off.
■Situations unsuitable for LKA system
Do not use the LKA system in the follow- ing situations.The system may not operate properly
and lead to an accident, resulting in death or serious injury.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively
worn, or when the tire inflation pres- sure is low.
●Tires which differ by structure, manu-facturer, brand or tread pattern are
used.
●Objects or patterns that could be mis- taken for white (yellow) lines are pres-ent on the side of the road (guardrails,
curbs, reflective poles, etc.).
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Asphalt repair marks, white (yellow) line marks, etc. are present due to road repair.
●Vehicle is driven in a temporary lane or
restricted lane due to construction work.
●Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven in traffic lanes other than on highways and freeways.
●Vehicle is driven in a construction zone.
■Preventing LKA system malfunctions
and operations performed by mistake
●Do not modify the headlights or place
stickers, etc. on the surface of the lights.

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.
