When the System Cannot Work
Normally
Please be aware that the radar sensor of
Park Assist System may not alarm or may
give wrong alarms under the following
conditions:
When barriers cannot be detected
• The radar sensor of Park Assist System
cannot detect net-shaped barriers like
iron wires, mooring ropes and blocking
net.
• The radar sensor of Park Assist System
cannot detect low barriers like stone,
wood blocks, etc.
• The radar sensor of Park Assist System
cannot detect vehicles with a high
chassis.
• The parking radar system sensor cannot
detect soft objects like snow, cotton,
sponge which can absorb the ultrasonic
wave.
• The radar sensor of Park Assist System
cannot detect barriers of some special
shapes, such as pillars, trees, bicycles,
angle steel, cornerstone and corrugated
paper.
Situations in which wrong alarm may be
given
• Ice on the sensor surface of parking
radar system.
• The vehicle is on a steep slope.
• The vehicle is fitted with high-frequency
radio or antenna or they are used nearby.
• Horn sound of other vehicles, roar of
engine or exhaust sound of vehicle are
too close to the parking radar system
sensor.
• Driving in snow or rain.
If the system still does not alarm when the
vehicle approaches to the obstacle, and it is
confirmed that it is not caused by the above
situation, please contact an authorized
PROTON service outlet for maintenance.
• The sensor of parking radar system can
only detect closest barrier when there are
several barriers. Please note whether the
parking sensor of another side detects
other barrier when vehicle moves.
• The parking radar system can only
display the closest barrier when there are
several barriers on the same side (front/
rear). Please pay attention to the
situation where the Park Assist System
radar sensor detects multiple obstacles
when vehicle moves.
• Do not use water gun to directly spray
high pressure water and do not squeeze
or impact the surface of parking radar
system sensor in other ways. Otherwise,
it may cause faults.
