ESP Seat Mii 2016 Workshop Manual

Care and maintenance
The optimal reach of the equipment is only
ac hiev
ed w
ith an external aerial.
Check first with a specialised workshop that
understands the technical possibilities of in-
stallation if you wish to use a two-way radio
with a transmitting power of over 10 watts.
SEAT recommends taking your car in for tech-
nical service.
All legal requirements, together with the in-
structions for the use of two-way radios must
be observed. WARNING
If the two-way radio is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury.
● While driving, two-way radios must be se-
curely
fastened in position, outside the air-
bags deployment zones, or safely stowed
away. WARNING
When using a two-way radio without a con-
nection to an e xt

erior aerial, the maximum
permitted levels of electromagnetic radiation
may be exceeded. This is also the case if the
aerial has not been correctly installed.
● You should only use a two-way radio inside
the vehic
le if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
u
nit
s Your vehicle is fitted at the factory with a ser-
ies
of

electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The v ehic

le control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli- ances connected in the vehicle, it is possible
to send the v

ehicle position. If the control
unit records an accident with airbag activa-
tion, the system may automatically send a
signal. This will depend on the network oper-
ator. Normally, transmission is only possible
in areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. Vehicles with airbag systems can store
data relating to impact speed, seat belt sta-
tus, seat positions and airbag activation
times may be stored, etc. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle owner
and, in some countries, they are governed by
local legislation.
Reprogramming control units
On the whole, all the data required for the
component management is stored in the con-
trol units. The programming of certain con-
venience functions, such as the turn signals,
individual door opening and instructions on
the display can be modified using special »

Introduction The dye from many items of modern clothing
(e.g. d
ark

jeans) is not always colour-fast.
Seat upholstery (material and leather), espe-
cially when light-coloured, may visibly discol-
our if the dye comes out of clothing (even
when used correctly). This is not an uphols-
tery defect but indicates that the dye in the
item of clothing is not sufficiently colour-fast. WARNING
Car-care products may be toxic and hazard-
ous. If c

ar care products are not suitable or
are used inappropriately, this could result in
accident, serious injury, burns or intoxica-
tion.
● Car care products must always be stored in
the original
container which should be kept
closed.
● Observe information provided by the manu-
factur
er.
● To prevent confusion, never store car care
products
in empty food cans, bottles or other
containers.
● Keep all care products out of reach of chil-
dren.
● Harmfu

l vapours may be produced when us-
ing car c
are products. Therefore, care prod- ucts should only be used in well-ventilated
sp
ac

es or in the open air.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid to wash,
clean or care for the vehicle. These are toxic
and highly flammable. WARNING
Inappropriate care and cleaning of vehicle
c omponent s

may effect the vehicle safety
equipment, increasing the risk of severe in-
jury.
● Vehicle components should only be
cle
aned and maintained in accordance with
the manufacturer's instructions.
● Only use approved or recommended care
products. CAUTION
● Cle

aning products which contain solvents
will damage the material.
● To avoid damage, stubborn stains should
be remov
ed by a specialised workshop. Note
Suitable vehicle care products are available
from y

our technical service. How to care for the upholstery
To treat and maintain your seat upholstery,
keep the f
o

llowing in mind ››› :
● Before entering the vehicle, close any Vel-
cr o f

asteners that might snag on the uphols-
tery or trim fabric. Any open Velcro fasteners
may damage the trim or upholstery fabrics.
● To prevent damage, avoid direct contact
between sharp dec
orative objects and the
upholstery and trim fabrics. Decorative ob-
jects include zips, rivets and rhinestones on
clothing and belts.
● From time to time, clean the dust that gath-
ers in the per

forations, folds and seams so
that the surfaces of the seats are not dam-
aged by its abrasive effect.
● Make sure clothes are colour-fast to avoid
them running and s
taining the upholstery.
This is especially important if the upholstery
is light in colour. CAUTION
If the instructions for upholstery and trim
car e ar

e not followed, they may deteriorate
and discolour. Note
SEAT recommends you take the vehicle to a
Spec i

alised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. 176

Care and maintenance
Cleaning padding and textile covers Normal cleaning
● Before applying cleaning products, please
re a
d the instructions for handling and the
warnings shown on the container.
● The upholstery, textile covers, and carpet
should be r
egularly vacuumed (with vacuum
brush).
● We recommend that you use a soft sponge
or lint-free, mic
ro-fibre cloth for normal clean-
ing ››› .
Gener al
s

uperficial dirt on upholstery and
textile covers can be cleaned with a normal
foam cleaning product.
If the upholstery and the material trims are
very dirty, we recommend you have them
cleaned by a specialist cleaning form.
Cleaning stains
It may be necessary to clean the whole sur-
face and not only the stain itself. Especially if
the surface has been dirtied through normal
use. Otherwise, the stained area may be-
come lighter than the rest of the surface after
treatment.
Type of
stainCleaning the vehicle
Water-based
stains, e.g.
coffee or fruit
juice.– Use a sponge and wipe with a solu-
tion of water and wool wash.
– Dry with a dry, absorbent cloth.
Persistent
stains, e.g.
chocolate or
make-up.– Apply a washing paste a)
directly to
the stain and allow it to work.
– Apply clean water using a sponge or
damp cloth to remove the cleaning
product deposits.
– Dry with a dry absorbent cloth.
Grease-based
stains, e.g. oil
or lipstick.– Apply neutral soap or cleaning
paste a)
and allow it to work.
– Remove dissolved grease or colour
particles with an absorbent cloth.
– Then apply clean water. Take care not
to soak the upholstery.
a) Bile soap can be used as a cleaning paste. CAUTION
● Brushe s

should only be used to clean the
mats and floor mat! Other surfaces may be
damaged if a brush is used.
● Do not use steam cleaning equipment, as
the dirt bec
omes more encrusted in the mate-
rial when steam is applied.
● Never use brushes for cleaning damp mate-
rial
as they could damage the surface. Cleaning storage compartments,

Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
In natural gas engines
While in gear, the fuel level indicator gauge
appears in the fuel area with which it is flow- ing at that time. When the ignition is connec-
ted, the gaug

e first changes for a few sec-
onds to the petrol area to show the actual
level of this petrol. Then, the gauge moves to
the natural gas level. After turning on the en-
gine, the gauge changes to the area corre-
sponding to the operating mode at that time.
Problem: if the vehicle is left parked for a
long time just after refuelling, 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 pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
su lt

in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially 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 as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. 184

Checking and refilling levels
CAUTION
● Alw a
ys pay attention to any lit control
lamps and to the corresponding descriptions
and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregu
lar fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

se, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Vehicles with a natural gas engine
Every 6 months it is necessary to run on pet-
rol until the control lamp switches off  and
then the tank must be refilled. This is neces-
sary to ensure the efficient operation of the
system and the fuel quality required for run-
ning on gas. WARNING
Do not continue refilling once the fuel nozzle
ha s

switched itself off. The fuel tank may be
filled too much. As a result, fuel may spurt
out and spill. This could lead to a fire, explo-
sion and severe injuries. CAUTION
● Alw a

ys remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork. For the sake of the environment

● Rep

lace the dipstick, pushing it in as far as
it wi
ll go. If the dipstick to measure engine oil
has a mark, when you reintroduce it this
mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the oil dipstick again and check
the engine oil

● After reading the oil level, replace the dip-
stick
in the tube completely. WARNING
Oil could catch fire if it comes into contact
with hot en

gine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil
filler cap is correctly tightened. This will avoid engine oil spilling onto hot en-

converter and engine damage may occur.
● When refilling or changing service liquids,
ensur
e that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! For the sake of the environment
The oil level must never be above area A .
Otherw i

crankcase breather and escape into the at-
mosphere via the exhaust system. Engine oil consumption
The consumption of engine oil can be differ-
ent
fr
om one en

gine to another and can vary
during the useful life of the engine.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 1 ltr./2000 km. In the
case of new vehicles, the consumption can
exceed this figure over 5,000 kilometres. For
this reason the engine oil level must be
