Assistance Systems for Parking or

Backing

Reverse Sensor
The intelligent reverse sensor judges the
distance between the rear of the vehicle and
the obstacle via the ultrasonic transducer
installed on the rear bumper.
If the beep sounds once after you turn on
the ignition switch and shift to R (Reverse),
it indicates that the system is working
normally.
If the beep sounds twice, it indicates that
one transducer fails to work; if it beeps
three times, it indicates that two or more
transducers are not working normally.
The intelligent reverse sensor starts to work
immediately every time you turn on the
ignition switch and shift to R (Reverse).
When the distance between the vehicle and
the obstacle behind it is within about
1.5 1.0 m, the system beeps at long
intervals.
When the distance between the vehicle and
the obstacle behind it is within about
1.0 0.6 m, the system beeps at short
intervals.
When the distance between the vehicle and
the obstacle behind it is within about
0.6 0.4 m, the system beeps at shorter
intervals.
When the distance between the vehicle and
the obstacle behind it is within about 0.4 m,
the system beeps constantly.
To ensure backing up safely and to leave
enough time for the system to detect,
drive at a speed of 5 km/h or lower when
backing up.
Stop the vehicle immediately when a
constant beep is heard in case the vehicle
bumps into an obstacle behind it.
Do not knock the transducers hard or
wash them directly with a high-pressure
water gun, otherwise the transducers can
be damaged.
Something on the transducers such as
snow, mud and water drops can lead to
incorrect operation.
The system is likely to fail to detect the
following obstacles:
Those of a cone shape or acute angle
reflectors
Objects prone to absorb sound waves,
such as cotton and snow
Fine objects such as iron gauze and
ropes
Objects 30 cm or closer to the ground
or 1 m or higher than the ground
The system may detect these
obstacles first, but as they become
nearer and nearer to the vehicle, they
can get out of the effective detection
range, and not detected as a result.
When reversing down or up a slope, the
system may give a false warning
The system is likely to work abnormally
under the following circumstances:
Reversing the vehicle on an uneven
road, a road paved with round stones,
an uphill road, or grassland
Interference from ultrasonic noise,
metallic sound or high-pressure gas
emission sound of the same frequency
Something on the transducers
Height change of the vehicle rear under
heavy load
