USING AND DRIVING

Rear collision warning Rear collision warning
If vehicle speed is above 5 km/h and the
sensor detects a risk of collision from a
vehicle approaching too quickly from the
rear, the side mirror light indicator will flash
and and an alarm will sound to warn both
drivers involved.
Door open warning (DOW)*
Door open warning (DOW)*
• The DOW system detects conditions that
may endanger vehicle safety from the
rear when the vehicle stops and a door is
opened, and gives a light warning.
• The rear radar identifies targets within
close range from the rear on both sides,
detecting risk conditions, and warns the
driver accordingly.
• Detection targets include non-power-
driven vehicles like bicycles and other
smaller vehicles; as well as other
powered vehicles and pedestrians.
CAUTION
•The BSD system assists the driver in
monitoring side mirror blind spots,
but it cannot replace the driver's
subjective observation and judgment.
The driver must maintain control of
the vehicle at all times, and is fully
responsible for the vehicle.
•When a target vehicle is approaching
from behind at a high speed, the BSD
system may not be able to provide
adequate warning.
•The driver should ensure the normal
operation of the BSD system,
keeping the BSD radar sensors in
good condition. For example, if they
are covered in dirt, snow or other
obstructions, they need to be cleared
right away.
CAUTION
•Detection may be affected or delayed
in some environments, and when
the radar cross-sectional area of
the target vehicle is too small (it
may be a bicycle, electric moped or
pedestrian), the system will not be
able to identify risk, leading to false
alarms. In addition, detection may be
affected by noise or electromagnetic
interference, resulting in delays.
•If unrelated targets at the side rear
or rear (such as large roadside
barriers used during road repair, large
advertisement billboards by the road,
reflectors in tunnels, or other objects
with a large reflection cross-sectional
area) are wrongly selected as targets,
the BSD system will issue an alert.
•Under some circumstances, it will
be difficult for the system to assist
the driver and the detection system
may be affected or delayed. Possible
circumstances include, but are not
limited to:
»
The car coming from the rear
suddenly changes lanes;
» Sharp turns, slopes and other
scenarios may delay target
detection;
»
Relative target speed above
80 km/h;
» The target vehicle is obscured;
»
When the radar reflection cross-
sectional area of the target vehicle
is too small (it may be a bicycle or
electric moped);
» The curve radius is too small, or
when entering or exiting a curve;
» Severe weather, such as rain or
snow.
