Note
●
The sensor may not detect any obstacle that is closer to the car.
Warning
●
The parking assist system is used to assist the driver for parking and cannot replace
your personal judgment. Ensure that the car is driven on base of your observation.
●
Do not place accessories or other items on the sensor to detect obstacles; otherwise
it will affect the normal operation of the system.
●
In some cases, the system may not be operated normally; when the car approaches
certain objects, the system will not detect them. Therefore, always observe the
surroundings around the car, and do not rely on the system only.
■
Some car conditions and surrounding conditions may affect the sensor ability to
accurately detect the obstacles. The specific conditions are as follows:
●
There is dirt, water or fog on the sensor;
●
There is snow on the sensor or the sensor is frozen;
●
The sensor is covered in any way;
●
The car is obviously tilted or over-loaded;
●
The car is driven on particularly bumpy roads, slopes, gravel or grass roads;
●
The sensor is painted again;
●
Because of horn sound, motorcycle engine sound, air brake sound of large trucks
or other noise that generates ultrasonic wave, there is very noisy in the vicinity of
the car;
●
There is another car equipped with a parking assist system nearby;
●
The bumper or sensor is strongly impacted;
●
The car is approaching a higher or tortuous curb;
●
The car is in the hot sun or cold weather;
●
The sensor is installed on a non-original suspension.
■
In addition to the above cases, the actual distance to some obstacles may not be
judged correctly due to their shapes and materials. Must pay particular attentions to
the following obstacles:
●
Wires, fences, ropes, and etc.;
