2012 Seat Mii gas type

70Ensuring you are correctly and safely seated
WARNING
In the event of a fault in the airbag system, the airbag may not trigger
correctly, may fail to trigger or may even trigger unexpectedly, leading to
severe or fatal injuries.
● Have the airbag system checked immediately by a Specialised work-
shop.
● Never mount a child seat in the front passenger seat or remove the
mounted child seat! The front passenger airbag may deploy during an ac-
cident in spite of the fault.
CAUTION
Always pay attention to any lit lamps and to the corresponding descriptions
and instructions to avoid damage to the vehicle. 
Description and function of the airbag
The airbag can protect vehicle occupants in the event of an accidents, cush-
ioning the movement of the occupants in the direction of the collision in
frontal and side accidents.
Deployed airbags fill with a propellant gas. This causes the airbag covers to
break and the airbags to deploy extremely quickly in their entire deploy-
ment space within fractions of a second. When an occupant with the seat
belt properly fastened puts pressure on the inflated airbag, the propellant
gas escapes to absorb the force of the impact and slow the movement. This
reduces the risk of severe or fatal injuries. Airbag deployment does not
mean that other types of injury such as swelling, bruising and skin injuries
can be ruled out. Upon deployment of the airbag, friction can cause the
generation of heat.
Airbags do not protect the arms or the lower part of the body. The most important factors for triggering the airbag are the type of accident,
the angle of impact, the vehicle speed and the characteristics of the object
the vehicle hits. Therefore, airbags are not triggered every time the vehicle
is visibly damaged.
The activation of the airbag system depends on the magnitude of the decel-
eration of the vehicle caused by a collision, which registers through an elec-
tronic control unit. If the deceleration magnitude value is below the refer-
ence value programmed in the control unit, the airbags will not deploy de-
spite serious damage being caused to the vehicle by the accident. Damage
suffered by the vehicle, reparation costs or absence of damage suffered
from the accident are not indications of whether an airbag should have
been deployed. Due to the varying nature of collision situations, it is impos-
sible to define a speed range of the vehicle and reference values. For this
reason, it is not possible to cover all types of collisions and collision angles
resulting in the deployment of the airbag. Factors necessary for the airbag
to be deployed can be, the characteristics of the object (hard or soft)
against which the vehicle collides, the collision angle and the vehicle
speed.
Airbags act in conjunction with three-point seat belts in the event of certain
accidents, when the vehicle deceleration rate is severe enough to trigger
the airbags. Airbags only deploy once and only under certain circumstan-
ces. Seat belts remain present to offer protection in situations where air-
bags are not triggered or where they have already deployed. For example,
when a vehicle hits another after an initial collision or is hit by another vehi-
cle.
The airbag system is an integral part of the vehicle's passive safety system.
The airbag system can only work effectively when the occupants are wear-
ing their seat belts correctly and have adjusted the head restraints properly

Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while a test of the function is being carried out. They will
switch off after a few seconds.
In natural gas engines
The warning lamp  lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp  lights up when the vehicle is running in natural gas op-
erating mode. The warning lamp 
switches off when the natural gas is exhausted. The
engine changes to operate with petrol.
Problem: If the vehicle is left parked for a long time immediately after refuel-
ling, the gas level indicator does not accurately indicate the same level
shown after refuelling when the vehicle is started up again. This is not due
to a leak in the system, but to a drop in pressure in the gas tank for techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel supply, the power steering as well as all of the driver assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tions and instructions to avoid damage to the vehicle.
● Never run the fuel tank completely dry. An irregular fuel supply may lead
to ignition faults and unburnt fuel could enter the exhaust system. This
could damage the catalytic converter.

Problem: If the ambient temperature is very high, the natural gas pump pro-
tection against overheating disconnects this automatically.
●
Remove the plug from the gas filler mouth ⇒ Fig. 108 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank flap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place.
WARNING
Natural gas is a highly explosive, easily flammable substance. Incorrect
handling of the natural gas can cause accidents serious burns and other
injuries.
● Before refuelling with natural gas, the filling mouth must be correctly
engaged. If you can smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury. 

Types of fuel
The type of fuel to use when refilling will depend on the vehicle's engine.
You will find a factory-fitted sticker containing information on the type of
fuel for your vehicle on the inside of the fuel tank flap.
SEAT recommends the use of sulphur-free or low sulphur fuel to reduce con-
sumption and prevent engine damage.

Petrol types
Vehicles with petrol engines must refuel using unleaded petrol according to
European norm EN 228 ⇒ 
.
Petrol types are categorised according to their octane number (e.g. 91, 95,
98 or 99 RON (RON = “Research Octane Number”). You may use petrol with
a high octane number than the one recommended for your engine. Howev-
er, this has no advantage in terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sulphur content or sulphur-free fuel
to reduce fuel consumption for petrol engines.
Petrol additives
The quality of the fuel influences running behaviour, performance and serv-
ice life of the engine. Therefore, it is recommended to refuel with good qual-
ity petrol containing the corresponding petrol additives. These additives will
help to prevent corrosion, keep the fuel system clean and prevent deposits
from building up in the engine.
If good quality petrol with additives are not available or engine problems
arise, the necessary additives must be added when refuelling ⇒

Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives could seriously damage the engine and the catalytic
converter. Petrol additives with metal additives must never be used.
Available petrol additives for improvements in Anti-detonation ratings or oc-
tane ratings may contain metal additives ⇒ 
.
SEAT recommends “Genuine SEAT Additives for petrol engines”. These addi-
tives are available from Specialised workshops, who will inform you of their
application.
CAUTION
● Only use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel sys-
tem. Furthermore, it could lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could seriously damage the en-
gine and the catalytic converter.
● If, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suitable octane rating as soon as
possible.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● Just filling one full tank of leaded fuel or with other metal additives
would seriously impair the efficiency of the catalytic converter and could
damage it. 
Natural gas
Natural gas, in addition to others, can be in liquid form. Liquefied natural gas (LNG) is the result of heavy cooling of natural gas.
Therefore its volume is considerably reduced compared with compressed
natural gas (CNG). In vehicles with a natural gas engine, liquefied natural
gas cannot be directly refilled, given that the gas would expand excessively
in the vehicle gas tank.
Therefore, vehicles with a natural gas engine must only be refuelled using
compressed natural gas
⇒ 
.
Natural gas quality and consumption
Natural gas is divided into the groups H and L depending on its quality.
Gas type H has a superior heating power and inferior nitrogen and carbon
dioxide content than type L. The higher the heating power of the natural
gas, the lower the consumption will be.
However, the heating power and the proportion of nitrogen and carbon di-
oxide can fluctuate within the quality groups. Therefore, vehicle consump-
tion can also vary when using one type of gas only.
The engine management automatically adapts to the natural gas used ac-
cording to its quality. Therefore, different quality gases can be mixed in the
tank, without the need for comprehensive draining before applying a differ-
ent quality gas.
Natural gas and safety
If you can smell gas or suspect that there is a leak ⇒ 
:
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● You should obtain professional assistance. Have the fault repaired. 
