Front sensor
The front sensor will operate only when the speed is
less than about 15 km/h. It checks the approximate
distance from the front of the vehicle to the obstacle
at an angle to it.
If the gearshift handle is in P gear or the parking
sensor system switch is off, the front sensor will not
work.
When the parking sensor system switch is turned on,
the front sensor automatically resumes when the
vehicle decelerates from high speed to less than 12
km/h.
The following conditions may cause false alarms
or no alarm:
● There are noises close to the ultrasonic
sensor transceiver frequency band in the
sounds of vehicle horn, engine roar, vehicle
exhaust and tire inflation, which may cause
false alarms.
● When reversing on narrow areas, rough
roads, or uphill slopes, the system may detect
railings, trees, or sloping surfaces, which
may result in false alarms.
● When high-frequency radios or antennas are
installed or used nearby, false alarms may be
generated.
● No alarm or false alarm may be generated
when the sensor is frozen or dirty in rain or
snow.
Inability to detect obstacles:
● The ultrasonic sensor has a blind spot in
detecting obstacle. It cannot detect objects
under, under, or too close to or far from the
bumper.
● The parking sensor system cannot detect
net-shaped objects such as fine wires, ropes
and blocking nets; soft objects such as snow,
cotton and sponge that easily absorb
ultrasonic waves; low objects such as rocks,
wood blocks and curbs; and special-shaped
objects such as pillars, small trees, bicycle,
angles, cornerstones and corrugated paper.
● The surface of some articles does not reflect
the ultrasonic signals emitted by the sensor,
which makes it impossible to detect such
articles or people wearing such clothes.
