The driving assist system includes Speed Assist System  
(SAS), Lane Departure Warning System (LDW), Lane  
Departure Prevention System (LDP), Lane Keeping Assist  
System (LKA), MG Pilot System, Forward Collision  
Warning System (FCW), Automatic Emergency Braking  
System (AEB) and Automatic Emergency Braking System  
for Pedestrians (AEBP). Under certain conditions, the  
driving assist system can detect the road and environmental  
information ahead of the vehicle by utilising a front view  
camera and a front detection radar. This information is  
used to relay warning messages or provide assistance to  
help the driver control the vehicle more safely and reliably.  
The front view camera is located at the upper middle  
of the windscreen (in the interior rearview mirror base  
cover)the front detection radar is located at the lower  
middle of the front bumper.  
The front view camera will require re-calibration after any  
of the following operations:  
Removal and refitting of the front view camera.  
Replacement of the windscreen.  
Note: The calibration of front view camera requires  
professional knowledge and tools. If calibration is  
required, please seek an MG Authorised Repairer.

Note: After completing the calibration it is not  
possible to immediately select any driving assist  
options. The vehicle power system must be switched  
to the OFF position and then switched to ON/READY.  
Obstruction of the front view camera  
On occasion the front view camera view may become  
obstructed by foreign objects or stains on the glass.  
In these cases a prompt message will appear in the  
information centre. Please clean or wipe immediately.

STARTING & DRIVING  
In the following situations, the detection  
performance of front view camera will be  
affected:  
The outer surface of the windscreen is not clean  
(including wiper sweep).  
The windscreen is not cleaned regularly.  
The demist/defrost action on the windscreen inefficient  
in wet conditions.  
Driving in poor weather conditions where visibility is  
reduced due to thick fog, heavy rain or snow etc.  
The front view camera is affected by light, for example  
low light levels at night, poor auxiliary lighting, excessive  
backlighting in the view, light from oncoming vehicles,  
abrupt change of brightness such as quick bright/dark  
jump (tunnel entrance/exit), driving on surfaces with  
strong reflective properties (road surface covered with  
water or snow), or driving in places with insufficient  
light, such as tunnels, surrounded by tall buildings,  
underground parking lots, etc.  
Description of Front Detection Radar  
Calibration of front detection radar  
Front detection radar re-calibration is required after any of  
the following:  
Front detection radar mis-alignment failure, for example  
the position of the front detection radar has changed.  
Remove/refit the front detection radar or radar bracket.  
Remove/refit the front anti-collision beam.  
The four-wheel alignment parameters or the driving axis  
have changed.  
The front view camera is partially or fully blocked by  
obstacles, e.g. dust, foreign objects on the windscreen.  
The windscreen in view is damaged.  
Note: If the front detection radar is subject to strong  
vibration or slight impact, the mounting position of  
the front detection radar needs to be checked and  
re-calibrated as necessary.

performance issues.  
Front radar performance will be effected in the  
following situations:  
When the front detection radar is covered by mud,  
snow, excessive water (rain) or water spray from the  
road.  
4
When the radar or surrounding areas are covered by  
objects such as self-adhesive labels or auxiliary lamps.  
Some targets may affect and weaken the detection  
capability of the front detection radar, such as road  
barriers, fences and tunnel entrances.  
When the front detection radar is subject to strong  
vibration or slight impact.

Speed Limit Information Function (SLIF): The vehicle  
detects a speed limit sign (as shown above) at the  
roadside with the front view camera. The speed limit  
sign identified will be displayed on the instrument pack.  
When the vehicle speed exceeds the speed limit by a  
preset amount, a visual warning in the instrument pack  
will alert the driver to control the speed manually.  
The intelligent speed limit is an auxiliary  
function, it may display an incorrect speed  
limit value or no speed limit value in the  
instrument pack due to various factors. As  
a result, the vehicle speed is not restricted  
within the correct range. The driver still  
needs to observe the speed limit of the road  
traffic, and speeding is strictly prohibited.  
Manual Speed Assist (MSA): The driver sets the  
maximum speed using the adaptive cruise control  
lever. The system will actively intervene and keep the  
vehicle speed within the permitted maximum speed  
limit. And an acoustic warning and a visual warning  
will be available during the intervention. Please refer  
to the section “Speed settings of manual speed assist”.  
The front view camera cannot recognise  
speed limit signs painted on the road surface.  
The driver MUST observe these speed limits  
and adjust the their speed accordingly.  
Intelligent Speed Assist (ISA): The vehicle detects a  
speed limit sign (as shown above) at the roadside  
with the front view camera. The speed limit sign  
identified will be displayed on the instrument pack.  
The system will automatically intervene and maintain  
speed control to keep the vehicle speed within the  
permitted maximum speed limit. And an acoustic

OK button to turn on/off the speed limit information  
function.  
Note: It is recommended to switch off the speed  
limit information function and intelligent speed assist  
function when the km/h speed units are selected. In  
such situations, the system will only recognize the  
number displayed in all speed limit signs and use this  
data for km/h, even if the speed limit sign refers to  
mph. When km/h is selected, the system will also  
recognize the national speed limit sign as a speed limit  
sign of 60km/h.

Note: When the vehicle needs to change lane, make a  
turn or turn around at an intersection and the driver  
uses an indicator in advance and slows down, the  
original speed limit value on the instrument pack will  
be reset and displayed as “—” until a new speed limit  
sign is detected. If the conditions are not met, the  
original speed limit value will be maintained and not  
be reset. The driver MUST observe the speed limits  
and adjust the their speed accordingly.  
this function cannot be turned on, please contact an MG  
Authorised Repairer.  
When the speed limit information function or  
intelligent speed assist function is enabled, and the front  
view camera detects a speed limit sign with text message  
below, the warning lamp illuminates yellow to remind  
the driver to recognise the text message by themselves.  
The camera cannot recognise the text messages provided  
below the speed limit sign, such as auxiliary lane, 100m  
ahead, school section, 7:00-10:00. The camera will  
recognise the speed limit sign with text messages as a  
normal speed limit sign. The driver is required to make  
correct judgement according to the text message.

The camera may not correctly recognise speed limit  
signs during poor lighting conditions, bad weather,  
non-standardized or sheltered speed limit signs  
or the camera’s own restrictions which include  
the recognition of similar signs (e.g., recognise a  
weight limit sign as a speed limit sign, or recognise a  
minimum speed sign as the maximum speed sign).  
Some drastic or rapid steering operations made by  
the driver may be judged as changing lane or turning  
around at an intersection by the system. This will  
result in the identified speed limit signs being cleared.  
The lane departure warning system does not  
always recognise the lane line. Sometimes  
poor road surfaces, certain road structures or  
objects may be mistaken for lane lines. When  
such situations occur, the lane departure
