136 4-5 Driving Auxiliary Functions
■ When the vehicle runs on a different line to a vehicle ahead with a too small
overlap ratio, the ACC system cannot identify such vehicle ahead as the target
vehicle; in this case, the driver should keep control of the vehicle.
■ When the vehicle follows a vehicle ahead to stop, in very few cases, the ACC
system cannot identify the rear end of the vehicle ahead but the lower rear end
of the target (e.g., the rear axle of a truck with high chassis or bumper of a
vehicle). In these cases, the ACC system cannot guarantee a proper distance
for stopping and the driver must stay alert and always get ready to brake.
■ The radar sensor may be affected by vibration or collision, resulting in
performance reduction of the ACC system. In this case, contact a BYD
authorized service provider.
■ The radar sensor is mounted in the front area of the vehicle. It should be noted
that the visual field of the sensor should not be covered by contaminants;
otherwise, its intended function will suffer interference. Especially when snow
completely covers the sensor, the system will quit. The system will send its quit
information to the driver via the man-machine interface. In this case, remove
contaminants, restart the vehicle or drive along the normal road for a certain
distance to allow the system function to return to normal.
■ If the vehicle is running under special road conditions such as a circular
parking lot or a tunnel for a long time, the radar sensor may malfunction for a
short time due to its detection characteristics. In this case, you can restore the
function by restarting the vehicle or driving along a normal road for a certain
distance.
■ Structural modification of the vehicle such as lowering the chassis height may
affect the ACC system.
■ Metal objects such as rails or metal plates for road construction may interfere
with the sensor and make it unable to work normally.
■ Do not use the ACC system when driving on a road with poor visibility, ramp or
curved sections or on slippery surface (e.g. snow, ice or water covered or
damp road sections).
■ In case of the following situations, please go to a BYD authorized service
provider for professional calibration and confirmation of the mid-range radar:
● Four-wheel alignment is performed due to wheel deviation.
● Vehicle collision has occurred.
● It is detected that the ACC system performance degrades or the
instrument prompts system abnormality.
Intelligent cruise control system
The intelligent cruise control (ICC, if any) system functionally integrates the
adaptive cruise control (ACC) system and lane keeping system (LKS). It can
provide the driver with longitudinal and lateral auxiliary control of the vehicle in the
full speed range of 0~130km/h, reduce the driver's driving burden and provide a
safe and comfortable driving environment. When the function is activated, the driver
is required to hold the steering wheel at all times and take over the control of the
vehicle if necessary.
