zTowing eyelets are installed.
z The bumper or sensor receives a strong
impact.
z The vehicle is approaching a tall or curved
curb.
z In harsh sunlight or intense cold weather.
z The area directly under the bumpers is not
detected.
z If obstacles draw too close to the sensor.
z A non-genuine Lexus suspension (lowered
suspension etc.) is installed.
People may not be detected if they are
wearing certain types of clothing.
z The shape of the obstacle may prevent a
sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections project- ing outwards in the direction of your vehi-
cle
z The following situations may occur during
use.
• Depending on the shape of the obstacle
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they are too close to the sensor. • There will be a short delay between
obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• Thin posts or objects lower than the sen- sor may not be detected for collision
when approached, even if they have been
detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow
noise of air conditioning system.
z In addition to the examples above, there
are instances in which, because of their
shapes, signs and other objects may be
judged by the sensor to be closer than
they are.
WA R N I N G
●When using the Lexus parking assist-sen-
sor
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be driven safely and pos-
sibly cause an accident.
• Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
• The sensors’ detection areas and reac- tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and drive
slowly, using the brake to control the
vehicle’s speed.
• Do not install accessories within the sensors’ detection areas.
