2014 Seat Mii engine overheat

Care and maintenance
consumables should be changed at a speci-
alised workshop. Technical services are per-
manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sumables may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their original container.
● Never store fluids in empty food containers
or bottles as other people may accidentally
drink the fluid.
● Keep all fluids and consumables out of
reach of children.
● Read and observe the information and
warnings given on the fluid containers.
● Only work in the open air or in well-ventila-
ted zones, when using products which give
off harmful vapours.
● Never use fuel, turpentine, engine oil, ace-
tone or any other volatile liquid in the main-
tenance of the vehicle. These are toxic and
highly flammable. They could lead to fire or
explosions! CAUTION
● Only use appropriate fluids. Do not confuse
fluids as this can cause serious malfunctions
or engine damage.
● Accessories and other components moun-
ted in front of the air inlet reduce the cooling effect of the coolant. If the engine is running
under great strain in high outside tempera-
tures, it could overheat.
For the sake of the environment
Leaking fluids could pollute the environment.
Collect any spilt fluids in suitable containers
and dispose of them in accordance with legis-
lation and with respect for the environment. Repairs and technical changes
When performing repairs and technical mod-
ifications, SEAT's directives must be ob-
served!

›
›› Unauthorised modifications to the electronic
components or software in the vehicle may
cause malfunctions. Due to the way the elec-
tronic components are linked together in net-
works, other indirect systems may be affec-
ted by the faults. This may significantly affect
the vehicle's performance, increase compo-
nent wear and could mean that the vehicle
registration documents are no longer valid.
Your SEAT Official Service cannot be held lia-
ble for any damage caused by technical mod-
ifications or repairs performed incorrectly.
The SEAT Official Service does not accept lia-
bility for damage resulting from technical
modifications or repairs performed incorrect-ly; neither is the SEAT warranty valid in these
cases.
SEAT recommends you have any technical
modifications or repairs performed at a SEAT
Official Service and that you use
genuine
SEAT spare parts ®
.
Vehicles with special accessories and
equipment
The manufacturers of additional equipment
guarantee that the equipment complies with
applicable laws and regulations with respect
to the environment, in particular Directives
2000/53/CE and 2003/11/CE. The first direc-
tive governs the disposal of end-of-life vehi-
cles while the second refers to the restric-
tions on the marketing and use of certain
dangerous substances and preparations.
The vehicle owner should keep the documen-
tation for the additional equipment safely
and hand it over to the scrap yard at the end
of the vehicle's service life. This ensures that
any additional equipment mounted in end-of-
life vehicles is correctly disposed of with re-
spect for the environment. WARNING
Repairs or modifications which are not per-
formed correctly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the driver assist systems. This
could result in serious accident. » 119Technical specifications

Checking and refilling levels
The vehicle is only prepared for refuelling
with Compressed Natural Gas (CNG) ››› . Re-
fuelling with another type of natural gas is
not allowed, e.g. Liquefied Nature Gas (LNG)
or hydromethane.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central locking button  situated on the driv-
er door ›
›
› page 48.
● Press on the rear area of the flap and open
it.
Refuelling
Problem:
If the ambient temperature is very
high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
››› Fig. 104
1 .
● Connect the pump filling nozzle to the gas
filler mouth.
● The fuel tank will be full when the pump
c ompr

essor 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 cap
●
Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
sary, 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 flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing 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. Note
● The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. ●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet
Working in the engine compartment Before working in the engine compartment,
make sure that the vehicle is parked on hori-
zontal and firm ground.
The engine compartment of the vehicle is a
hazardous area. Never work on the engine or
in the engine compartment if you are not fa-
miliar with the operations to be carried out,
the applicable safety standards and especial-
ly if you do not have the necessary instru-
ments, liquids and tools
››› ! If required,
have any work carried out by a specialised
workshop. Negligent work can cause serious
injury. WARNING
If the vehicle moves unexpectedly, this could
cause serious injury. » 143

Advice
CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Never plug accessories that supply current,
such as solar panels or a battery charger, to
the 12-volt power socket or the cigarette
lighter. This could damage the vehicle's elec-
trical system. For the sake of the environment
Dispose of the battery in an environment-
friendly manner. Batteries contain toxic sub-
stances such as sulphuric acid and lead. For the sake of the environment
Battery acid can contaminate the environ-
ment. Collect any spilt service fluids and dis-
pose of them correctly. Wheels and tyres
Wheels Introduction SEAT recommend that all work on tyres and
wheels is carried out by a specialised work-
shop. These workshops have the necessary
special tools and replacement parts, trained
personnel and facilities for disposing of the
old tyres while respecting the environment.
SEAT recommends taking your car in for tech-
nical service.
WARNING
The vehicle cannot be totally controlled or
braked if the tyres (new or used) are worn or
damaged.
● Incorrect use of wheels and tyres could
make driving more dangerous and result in
serious accidents and damage.
● All four wheels must be fitted with radial
tyres of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● New tyres do not give maximum grip and
will not have reached their maximum braking
capacity to start with, and therefore need
running in. To prevent accidents and major
damage, extreme caution should be taken for
the first 600 km. ●
Check tyre pressures regularly and ensure
they are maintained at the pressures indica-
ted. If the tyre pressure is too low, they could
overheat, resulting in tread detachment or
even burst tyres.
● Never drive on damaged (punctured, cut,
cracked or dented) or worn tyres. Driving on
damaged or worn tyres could result in burst
tyres, serious accidents or damage. Worn or
damaged tyres must be replaced immediate-
ly.
● Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle.
● The effectiveness of driver and brake assist
systems also depends on the grip of the
tyres.
● If you notice unusual vibration or if the ve-
hicle pulls to one side when driving, stop the
car immediately and check the tyres and
wheels for damage.
● To minimise the risk of losing control of the
vehicle or causing a serious accident, never
undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are
not sure of their previous history. They may
be damaged, although the damage is not im-
mediately visible.
● Old tyres, even if they have never been
used, may lose air or burst unexpectedly
while driving, especially at high speeds, re-
sulting in serious accident and injury. If tyres
are over six years old, they should only be
used in an emergency and with extreme cau-
tion. 158
