For safety and security
NOTICE
●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 your Lexus dealer.
●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.

for a door to open and whether a strong
wind is blowing. When opening or clos-
ing the door, hold the door handle tightly
to prepare for any unpredictable move-
ment.
■Vehicle height co ntrol precautions
(vehicles with electronically modu-
lated air suspension)
In the following situations, make sure to

Driving
WARNING
●Vehicles with Lexus Safety System + A:
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.
■If the vehicle becomes stuck
Do not spin the wheels excessively when
a driven wheel is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and
brake pedals at the same time during
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.
■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.
■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.
●When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
●Make sure to idle the engine immedi-
ately after high-load driving. Stop the
engine only after the turbocharger has
cooled down.
Failure to do so may cause damage to
the turbocharger.
■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.438)
■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 your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, transfer (AWD models), differen-
tial, etc.
●Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.

WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not auto-
matically 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 driving safely by pay-
ing careful attention to the surround-
ing conditions and operating 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.
●When not using the LTA system, use
the LTA switch to turn the system off.
■Situations unsuitable for LTA system
In the following situations, use the LTA
switch to turn the system off. Failure to do
so may lead to an acc ident, resulting in
death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven on a snow-covered
road.
●White (yellow) lines are difficult to see
due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or
restricted lane due to construction
work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been excessively
worn, or when the tire inflation pres-
sure is low.
●During emergency towing.
■Situations in whic h the lane change
assist function should not be used
●When driving on a one lane road or
road without lane markers
●When there is no broken white line
between your vehicle and the lane
toward which the turn signal is oper-
ated
●Vehicle is driven in traffic lanes other
than that freeways and highways.
■Preventing LTA system malfunctions
and operations performed by mistake
●Do not modify the headlights or place
stickers, etc. on the surface of the
lights.
●Do not modify the suspension etc. If
the suspension etc. needs to be
replaced, contact your Lexus dealer.
●Do not install or place anything on the
hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar,
etc.).
●If your windshield needs repairs, con-
tact your Lexus dealer.
■Conditions in which functions may
not operate properly
In the following situations, the functions
may not operate properly and the vehicle
may depart from its la ne. Drive safely by
always paying careful attention to your
surroundings and operate the steering
wheel to correct the path of the vehicle
without relying solely on the functions.

2984-5. Using the driving support systems
Brake function (rear pedestrians) differs
from the detection area of the RCD func-
tion (P.282). Therefore, even if the RCD
function detects a pedestrian and provides
an alert, the Parking Support Brake function
(rear pedestrians) may not start operating.
■Situations in which the system may not
operate properly

• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skateboard, or other light vehicle
• Pedestrians wearing oversized clothing such as a rain coat, long skirt, etc., making
their silhouette obscure

pedestrians), preventing the function
from operating properly:
