For safety and security
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●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 seats, the glove box, 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.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency 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 ascer-
tain the level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emergency and helps to
dispatch the necessary emergency services. ( P. 6 0 0 )

4-5. Using the driving support systems
■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system, is in use, the warn-
ing indicator will appear in the top right of the screen even if the display setting has
been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumpers.
●Certain vehicle conditions and the surrounding 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 frozen the screen may show an abnor-
mal display, or obstacle s 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.
• 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 th e 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 se nsor to be closer than they
are.
