Instructions for Use of Hybrid Vehicle* for Your Mg HS SUV Second Generation (2024-2026)

INSTRUCTIONS BEFORE USING THE VEHICLE  
Instructions for Use of Hybrid Vehicle*  
The high-voltage battery packs contain many lithium cells.  
Arbitrary disposal may cause pollution and harm to the  
environment. Therefore, they should be recycled and  
disposed by MG Authorised Repairers or designated  
cooperation units by observing the following information  
or requirements.  
1
Ambient temperature for using vehicle  
The working performance of the high-voltage battery  
pack fitted to your vehicle is related to the ambient  
temperature. This battery powers the vehicle power  
system and therefore it is recommended that where  
possible the vehicle should be used within the temperature  
range of -15~45. This will ensure that the vehicle  
is in the optimum working state and help extend the  
service life of the high-voltage battery pack. Extremely  
high or low temperatures will affect the performance of  
the high-voltage battery pack and vehicle.  
Personnel: ONLY qualified personnel should dismantle  
the high-voltage battery pack;  
High-voltage safety: the high-voltage battery pack  
features high-voltage components such as lithium  
battery pack and high-voltage harness. DO NOT  
attempt to dismantle any component of this system,  
suitably trained professional staff must observe  
insulation safety protection before working on or near  
the high voltage system.  
Instructions for recycling high-voltage  
battery packs  
Transportation requirements: The high-voltage battery  
pack is classified as a Category 9 hazardous material  
and must be transported by companies with relevant  
qualifications.  
If you decide not to use the recommended  
MG Authorised Repairer to dispose of your  
high voltage battery, the responsibility  
of the consequences of environmental  
pollution or accidents must be bourne by  
the owner.  
Storage requirements: All high-voltage components  
(including the high-voltage battery pack) should be  
stored at room temperature and in a dry environment.  
25  
INSTRUCTIONS BEFORE USING THE VEHICLE  
They must be kept away from dangerous sources, such  
Precautions in the Event of an Accident  
as flammable objects, heat and water sources.  
Ensure the vehicle is in P gear and the  
vehicle power system is OFF.  
It is strongly recommended that the used high-voltage  
battery pack generated from vehicle scrappage, etc. should  
be disposed of by an MG Authorised Repairer. Please  
consult an MG Authorised Repairer for more details.  
If any cables on the vehicle are exposed,  
in order to prevent electric shock or even  
death DO NOT make any contact with any  
cable.  
If the vehicle catches fire but the fire is small  
and slow, a carbon dioxide extinguisher  
can be used to extinguish the fire. Please  
ensure this is only done if it is safe to do  
so and contact the fire services as soon as  
possible. If the fire is large and spreading  
quickly, immediately evacuate the vehicle  
and contact the fire services.  
If the vehicle is involved in a collision and  
it cannot be restarted, the negative cable  
of the12V battery and Manual Service  
Disconnect (MSD) MUST be disconnected  
prior to rescue.  
26  
INSTRUCTIONS BEFORE USING THE VEHICLE  
When the vehicle is completely or partially  
1
immersed in water, switch off the vehicle  
power system and evacuate the car  
immediately. The negative cable of 12V  
battery and Manual Service Disconnect  
(MSD) MUST be disconnected prior  
to rescue or as soon as the vehicle is  
refloated/removed from the water. Observe  
the water/vehicle for any abnormal signs  
such as excessive bubbles or noises, this  
may indicate battery short circuit issues. If  
no signs are evident, there should not be a  
shock risk from the bodywork and recovery  
can commence.  
After the accident is resolved, please  
contact an MG Authorised Repairer for  
maintenance.  
27  
INSTRUCTIONS BEFORE USING THE VEHICLE  
High Voltage System  
All high voltage components have warning  
labels attached  
-
please observe these  
warnings and any requirements when  
operating within or close to these areas.  
ONLY qualified personnel should work on,  
or with, the high voltage system - there is  
danger of DEATH.

INSTRUCTIONS BEFORE USING THE VEHICLE  
Crash Outage Control  
1
If a serious collision occurs, a signal from the SDM will  
disconnect the relays within the High-voltage battery  
back to cut off the high-voltage output of the high-voltage  
battery pack.  
Intelligent Charging  
When the vehicle is powered OFF and the system  
detects that the 12V battery is running low, the vehicle  
will automatically charge the 12V battery under certain  
conditions to ensure the vehicle starts. This function will  
be automatically turned off upon completion of charging.  
Note: The system will suspend intelligent charging if a  
fault is present, when starting or the vehicle is being  
charged by an external device.  
Note: The driving range will be reduced after  
intelligent charging.  
Note: The intelligent charging function is suspended  
when the high voltage battery is in a low SOC.  
Note: The engine will not be started when this  
function is turned on.
