SEATS AND PROTECTIVE DEVICES
The frontal air bag is designed to be inflated in
moderate to severe head-on collision or
almost head-on collision to reduce severe
injury risks of the driver’s and the front
passenger’s head and chest.
Whether the frontal air bag is inflated do not
mainly depends on the vehicle running speed.
It depends on the impacted object, impact
direction and vehicle deceleration within unit
time during collision.
The frontal air bag may be inflated in different
collision speed. The air bag inflation depends
on the impact direction (straight or in certain
angle) at the moment of collision and whether
the impacted object is fixed or movable,
deformable or not and narrow or wide. Due
to different design of each vehicle, the collision
inflation conditions of the frontal air bag may
vary. The frontal air bag will not be inflated in
case of vehicle overturn, rear-end collisions
and most lateral-impact collisions. The frontal
air bag may not be inflated in slight head-on or
nearly head-on collisions, lateral or diagonal
collisions, collisions to cylindrical objects
(such as telegraph pole and tree trunk), rear-
end collisions under large vehicle (trucks, etc.)
breast board and lateral glancing collisions. As
per the design, the seat lateral-impact air bag
and the side curtain air bag will be inflated
according to the impact position in case of the
moderate to severe lateral collisions.
The seat lateral-impact air bag and the side
curtain air bag will not be inflated in case of
head-on collisions, nearly head-on collisions,
vehicle overturn or rear-end collisions. The
seat lateral-impact air bag and the side curtain
air bag may not be inflated in slight side
collisions and lateral-frontal or diagonal
collisions.
As per the design, the seat lateral-impact air
bag and the side curtain air bag will be inflated
on the side to which the vehicle is collided.
The air bag will not be triggered in all collision
accidents. For a particular accident, it shall not
simply judge whether the air bag should be
inflated according to the causalities, vehicle
damage or repair and maintenance expenses.
Your vehicle is equipped with a collision
sensing and diagnosis module. If a collision
accident reaches certain strength, the module
may record relevant collision information
after the collision. If you have any doubt on the
working situation of your air bag in a collision
accident, please contact the MG Authorised
Service Center timely to provide professional
analysis and diagnosis for you.
How is the Air Bag Inflated?
In the inflation process, the sensing system will
send an electronic signal to trigger the gas
generator; the generator will release gas to
inflate the air bag and to make the air bag pops
up from the cover plate. The gas generator, air
bag and relevant members are all components
of the air bag module.

Protection?
The air bag supplements protection provided
by the seat belt by distributing the impact force
more evenly to the occupant’s body.
However, some occupants’ bodies do not
move toward the air bags in collisions where
an external object intrudes into the vehicle.
The air bag cannot provide corresponding
protection. The air bag shall only be deemed as
a supplementary device of the seat belt.
What Will You See After the Air Bag is
Inflated?
After the air bag is inflated, it will be deflated
quickly. Somebody may not note that the air
bag is ever inflated because the bleeding speed
is very fast. For deflated air bag, some smoke
and dust may come out from its air event.
When Shall the Air Bag Be Inflated?
SEATS AND PROTECTIVE DEVICES
If the vehicle power supply system can still
function normally after a collision, the vehicle
has the functions of unlocking doors
automatically, turning on the hazard warning
lamp and cutting off the fuel system after the
air bag is inflated. The driver can use
corresponding function switch to lock doors,
turn off indoors lamps and turn off the hazard
warning lamp.
The deployment of the front passenger air bag
may also cause damage to the windshield.
• The air bag can only be inflated once as per
its design. After the air bag is inflated,
some parts of the air bag system need to
be replaced. If you do not have these parts
replaced, the air bag system will unable to
provide protection in next collision
accident. The air bag system parts that
shall be replaced include the air bag
module, air bag control module, seat belt
pretensioner and other parts.
• Work related to the air bag system can
only be done by technicians with
corresponding qualification. Improper
repair and maintenance may cause that
the air bag system cannot function
normally. Please drive to the MG
Authorised Service Center for repair and
maintenance.
Air Bag System Repair, Maintenance and
Replacement
The air bag system must be maintained by
qualified and professional technicians. Improper
maintenance will cause that the air bag system
cannot function normally. Please drive to the
MG Authorised Service Center for repair and
maintenance of the air bag system.
If the air bag cover is damaged, opened or
broken, the air bag may not function
normally. It shall be repaired as soon as
possible.
Warning
Never stick or cover any object on the air
bag cover surface or refit the air bag
cover; never try to repair, adjust or
remove or install any air bag system
component; never try to refit the front
bumper of the vehicle body by yourself.
Warning
The Frontal Air Bag May Not Be Inflated
in the Following Collisions
The frontal air bag will usually not be inflated in
case of side collisions, rear-end collisions,
turnover or low-speed head-on collisions. No
matter what kind of collision, only when the
vehicle generates sufficient forward
deceleration, will the frontal air bag be inflated.
• Head-on collision angle over 30° from
vehicle longitudinal direction
When the air bag is inflated, there may be
dust spread in the air. All persons in the
vehicle shall get off the vehicle as soon as
possible. If you have a breathing problem and
cannot get off the vehicle, open windows or
doors to get fresh air. If you have a breathing
problem after the air bag is inflated, please
see a doctor as soon as possible.
