Intelligent Driving System
Medium-range Radar
1. Rear side medium-range radar
The Intelligent Driving System detects
targets through medium-range radar (also
known as mid-range radar) on both rear
side of the vehicle. During daily use, please
note the followings:
• Severe weather conditions, such as rain,
snow, fog, etc., will cause the
performance of the rear side medium-
range radar to deteriorate. In this case,
some targets may not be detected, or
being detected too late.
• Keep the rear side medium-range radar
clean. The surface area of the rear side
medium-range radar should be free from
any obstacles and pollutant, otherwise it
will affect the performance of the
intelligent driving system.
• Under certain environmental influences,
the performance of rear and side mid-
range radars may deteriorate.
• Do not refit or modify the rear side
medium-range radar. The calibration of
rear side medium-range radar may be
affected, subject to strong vibration and
slight impact.
If the surface area of rear side medium-
range radar is dirty or covered, the meter
instrument display will prompt in text and a
sound alarm to remind the driver to clean
the dirt, or drive on the road for a while after
cleaning it.
Blindness of rear side medium-range
radar is a normal reaction of vehicle
under specific road conditions. Make sure
the surface of rear side medium-range radar
is clean and then, drive the vehicle under
normal road conditions for a period of time.
The rear side medium-range radar will
automatically return to normal. If the radar
cannot recover by itself, please go to the
authorised PROTON e.MAS service outlet
for inspection and maintenance.
Under the following situations, go to an
authorised PROTON e.MAS service outlet
to have the rear side medium-range radar
professionally calibrated:
• The rear side medium-range radar has
been removed.
• The toe-in and/or rear wheel camber
have been adjusted during four-wheel
alignment.
• After a collision.
• The Intelligent Driving System is
degraded or abnormal.
