Reverse Sensor - MG Hector Owner's Manual

Reverse Sensor*

The intelligent reverse sensor judges the
distance between rear end of the vehicle and the
obstacle via the ultrasonic transducer installed
on the rear bumper.
If the buzzer buzzes once after you turn on the
ignition switch and shift to reverse gear, it
indicates that the system can work normally.
If the buzzer buzzes twice, it indicates that one
transducer fails to work; if it buzzes thrice, it
indicates that 2 or more transducers cannot
work normally.
The intelligent reverse sensor starts to work
immediately every time you turn on the ignition
switch and shift to reverse gear.
When the distance between the vehicle and the
obstacle behind it is within about 1.5 m~1.0 m,
the reverse buzzer sends out alarm sound at
long intervals.
When the distance between the vehicle and the
obstacle behind it is within about 1.0 m~0.6 m,
the reverse buzzer sends out alarm sound at
short intervals.
When the distance between the vehicle and the
obstacle behind it is within about 0.6 m~0.4 m,
the reverse buzzer sends out alarm sound at
shorter intervals.
When the distance between the vehicle and the
obstacle behind it is within about 0.4 m, the
reverse buzzer sends out alarm sound constantly.
Note
Ÿ Please note that the system is likely
to work abnormally due to wrong
i n d u c t i o n u n d e r t h e f o l l o w i n g
circumstances: reversing the vehicle
on an uneven road, a road paved with
round stones, an uphill road or
g r a s s l a n d ; i n t e r f e r e n c e f r o m
ultrasonic noise, metallic sound or
high-pressure gas emission sound of
the same frequency; sundries on the
transducers; height change of vehicle
rear end under heavy load; other
detecting equipment installed within
the effective detection range.

installed on the vehicle, usage of such
equipment (not including mobile
cellphone and audio system) may
affect the function of this system.
INSTRUMENTS AND CONTROLS
Note
To ensure reversing safety and to leave
Ÿ
enough time for the system to detect,
please drive at a speed of 5 km/h or lower
during reversing.
Please stop the vehicle immediately a
Ÿ
constant alarm sound is heard in case that
the vehicle bumps onto the obstacle
behind it.
Please do not knock the transducers hard
Ÿ
or wash them directly with a high-
pressure water gun, otherwise the
transducers can be damaged.
Sundries on the transducers such as snow,
Ÿ
mud and water drops can lead to
misoperation.
Ÿ Please note that the system is likely to fail
to detect the following obstacles: those of
a conical shape or acute angle reflectors;
objects which are prone to absorb sound
wave, such as cotton and snow; fine
objects such as iron gauze and ropes;
objects 30 cm or lower 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, not detected as a result.
Ÿ When reversing down or up a slope, the
system may give out a wrong warning,
reminding you to take great care.
