For safety and security
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, brui sing etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
front seats, parts of the front and rear pillars and roof side rails, may be hot for several
minutes. The airbag itself may also be hot.
●The windshield may crack.
●All of the doors will be unlocked. ( P. 114)
●Fuel supply to the engi ne will be stopped. (P. 517)
●For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
the system is designed to send an emerge ncy call to the response center, notifying
them of the vehicle’s location (without needing to push the “SOS” button) and an agent
will attempt to speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency ser-
vices. ( P. 71)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.

WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force
will be applied.
●If the vehicle is stopped by the operation of the pre-collision braking function, the pre-
collision braking function operation will be canceled after approximately 2 seconds.
Depress the brake pedal as necessary.
●The pre-collision braking fu nction may not operate if certain operations are per-
formed by the driver. If the accelerator pedal is being depressed strongly or the steer-
ing wheel is being turned, the system may de termine that the driver is taking evasive
action and possibly prevent the pre-coll ision braking function from operating.
●In some situations, while the pre-collision braking function is operating, operation of
the function may be canceled if the accele rator pedal is depressed strongly or the
steering wheel is turned and the system de termines that the driver is taking evasive
action.
●If the brake pedal is being depressed, the sy stem may determine that the driver is tak-
ing evasive action and possibly delay the op eration timing of the pre-collision braking
function.
■When to disable the pre-collision system
In the following situations, di sable the system, as it may not operate properly, possibly
leading to an accident resultin g in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, bo at, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running and the tires are allowed to
rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or
speedometer tester, or when using an on vehicle wheel balancer
●When a strong impact is applied to the fron t bumper or front grille, due to an accident
or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been
in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than specified are installed
●When tire chains are installed
●When a compact spare tire or an emergency tire puncture repair kit is used
●If equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is
temporarily installed to the vehicle

■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system or Multi-terrain Moni-
tor is in use, the warning indicator will appear in the upper corner of the screen even if the
display setting has been set to off.
■Sensor detectio n information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an obstacle. Pa rticular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, 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 gravel, 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 sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor re ceives 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 ar e instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

■Panoramic view display range
●In the panoramic view, the system processe
s and displays images acquired form the 4
cameras under the assumption that the vehicle is on a flat road surface. Therefore, the
display may appear as follows.
• Three-dimensional objects may appear to have fallen over, and be long and thin or bigger than they actually are
• Three-dimensional obje cts at a point higher than the surface of the road may appear
further away than they actually are, or may not appear
• Tall objects may appear to emerge from the image processing seams
●Inconsistencies in th e brightness of images from each camera may occur depending on
lighting conditions.
●The displayed image may not be aligned when the tilt or height of the vehicle changed
due to the number of passengers, cargo we ight or remaining quantity of gasoline.
●The displayed image may not be aligned when the vehicle is in other than “N” (normal)
height mode. (P. 339)
●Images and guide lines may not be properly displayed when the doors are not com-
pletely closed.
●The relative distances between the vehicle ic on and road surface or an obstacle dis-
played in the panoramic view may differ from the actual state.
●If an illuminated license plate is used, it may appear on the screen.
●The black area around the vehicle icon is an area that is not appear in the camera.
Check these areas directly.
■Wide front view display range
●Certain areas at the front of the vehicle ha ve a different sense of distance, and are
masked in black so that they do not appear on the screen.
●There are limits to the range displayed on the screen. Objects at either corner of the
bumper or directly below the bumper are not displayed.
●The perceived distance in images displayed on the screen differs from the actual dis-
tance.
■Images displayed on the screen
Cameras of the Multi-terrain Monitor system use special lenses. The distance of the
image that appears on the screen differs from the actual distance.
●The circled areas shown in the illustration may
be difficult to see, as these are points where
images are combined.
