LX570_OM_OM60Q78U_(U) 1
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, side and rear pillars and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.●
The windshield may crack. ●
For Lexus Enform 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 occupa nts to ascertain the
level of emergency and assistance required . If the occupants are unable to communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( → P. 452)WARNING ■

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 wher e 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 th e 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.
