2012 Seat Mii park assist

178At the filling station
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. 

210Vehicle care and maintenance
Wheels and tyres
Introduction
SEAT recommend that all work on tyres and wheels is carried out by a Speci-
alised workshop. They have the necessary special tools and replacement
parts, trained personnel and facilities for disposing of the old tyres. SEAT
recommends visiting a Technical Service.

● Braking, stopping and parking ⇒ page 134
● Caring for and cleaning the vehicle exterior ⇒ page 197
● Notes for the user ⇒ page 233
● Vehicle tool kit ⇒ page 246
● Wheel trims ⇒ page 248
● Change wheel ⇒ page 250
● Tire Mobility Set ⇒ page 256
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 circumference) 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 tak-
en for the first 600 km (400 miles).
WARNING (Continued)
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. If the tyre pressure is too low, the tyres could over-
heat, 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, seri-
ous accidents or damage. Worn or damaged tyres must be replaced im-
mediately.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
● The efficiency of driver and brake assist systems also depends on the
grip of the tyres.
● If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres and wheels for
damage.
● To minimise the risk of losing control of the vehicle or causing a seri-
ous 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 immediately
visible.
● Old tyres, even if they have never been used, may lose air or burst un-
expectedly while driving, especially at high speeds, resulting in serious
accident and injury. If tyres are over six years old, they should only be
used in an emergency and with extreme caution.
Note
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel. Please refer to the vehicle documents or ask at a Technical Service. 

250Practical information
Changing a wheel
Introduction
Some vehicle versions and models do not have a factory-fitted jack or box
spanner. In this case, we recommend consulting a Specialised workshop to
change the wheel.
You should only change the wheels yourself if the vehicle is parked in a safe
place, you are familiar with the procedure and you have all the necessary
tools! Otherwise, you should seek professional assistance.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Vehicle key set ⇒ page 28
● Wheels and tyres ⇒ page 210
● In case of emergency ⇒ page 240
● Vehicle tools ⇒ page 246
● Wheel trims ⇒ page 248
WARNING
Changing a wheel can be dangerous, especially on the hard shoulder.
Please observe the following rules to minimise the risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to change a wheel.
● When changing a wheel, keep all passengers and particularly chil-
dren a safe distance away from the work area.
● Turn on the hazard warning lights to warn other road users.
● Ensure the ground on which you park is flat and solid. If necessary,
support the jack on a wide solid base.
WARNING (Continued)
● If you are changing a wheel yourself, you should be familiar with the
required procedure. Otherwise, you should seek professional assistance.
● Only use suitable tools that are not damaged when changing a wheel.
● Always stop the engine, apply the handbrake lever firmly and place
the selector lever in position P, or engage a gear for a manual gearbox to
reduce the risk of the vehicle moving accidentally.
● Have the tightening torque of the wheel bolts checked as soon as
possible with a reliable torque wrench.

256Practical information
Anti-puncture kit*
Introduction
The Tyre Mobility Set* will reliably seal punctures caused by the penetration
of a foreign body of up to about 4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre, you must again check the tyre
pressure about 10 minutes after starting the engine.
You should only use the tire mobility set if the vehicle is parked in a safe
place, you are familiar with the procedure and you have the necessary tire
mobility set! Otherwise, you should seek professional assistance.
The tyre sealant must not be used in the following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20 °C (-4 °F).
● In the event of cuts or perforations in the tyre greater than 4 mm.
● If you have been driving with very low pressure or a completely flat tyre.
● If the sealant bottle has passes its use by date.
Additional information and warnings:

● Braking, stopping and parking ⇒ page 134
● Wheels and tyres ⇒ page 210
● In case of emergency ⇒ page 240
● Wheel trims ⇒ page 248
WARNING
Using the tire mobility set can be dangerous, especially when filling the
tyre at the roadside. Please observe the following rules to minimise the
risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to fill the tyre.
● Ensure the ground on which you park is flat and solid.
● All passengers and particularly children must keep a safe distance
from the work area.
● Turn on the hazard warning lights to warn other road users.
● Use the tire mobility set only if you are familiar with the necessary
procedure. Otherwise, you should seek professional assistance.
● The tire mobility set is intended for temporary, emergency use only.
Use only until you can reach the nearest specialised workshop.
● Replace the repaired tyre with the tire mobility set as soon as possi-
ble.
● The sealant is a health hazard and must be cleaned immediately if it
comes into contact with the skin.
● Always keep the tire mobility set out of the reach of small children.
● Never use the approved jack, even if it has been approved for your ve-
hicle.
● Always stop the engine, apply the handbrake lever firmly and engage
gear if using a manual gearbox, in order to reduce the risk of vehicle in-
voluntary movement.
WARNING
A tyre filled with sealant does not have the same performance properties
as a conventional tyre.
● Never drive faster than 80 km/h (50 mph). 

Practical information
Starting assistance
Introduction
If the engine fails to start because of a discharged battery, the battery of an-
other vehicle can be used to start the engine. Before starting, check the
magic eye on the battery ⇒ page 193.
For starting assistance, jump lead cables conforming to the standard
DIN 72553 are required (see the cable manufacturer instructions). The cable
section in vehicles with petrol engine must be at least 25 mm 2
.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
● Vehicle battery ⇒ page 193
WARNING
Incorrect use of jump leads and incorrectly jump starting could cause the
battery to explode resulting in serious injury. Please observe the follow-
ing rules to minimise the risk of a battery explosion:
● All work involving the vehicle battery and electrical system can cause
corrosion, fire and serious electric shocks. Always read and take into ac-
count the safety warnings and standards before beginning work on the
battery ⇒ page 193, Vehicle battery.
● The battery providing current must have the same voltage (12V) and
approximately the same capacity (see markings on battery) as the flat
battery.
● Never charge a frozen or recently thawed battery. A flat battery can al-
so freeze at temperatures close to 0 °C (+32 °F).
● If a battery is frozen and/or has been frozen then it must be replaced.
WARNING (Continued)
● A highly explosive mixture of gases is released when the battery is
being charged. Always keep lit cigarettes, open flames, sparks and fire
far from the battery. Never use a mobile telephone when connecting and
removing the jump leads.
● Charge the battery only in well ventilated areas given that when the
battery is charged by outside assistance, it creates a mix of highly explo-
sive gases.
● Jump leads should never enter into contact with moving parts in the
engine compartment.
● Never switch the positive and negative poles or connect the jump
leads incorrectly.
● Note the Instruction Manual provided by the manufacturer of the
jump leads.
CAUTION
To avoid considerable damage to the vehicle electrical system, note the fol-
lowing carefully:
● If the jump leads are incorrectly connected, this could result in a short
circuit.
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected. 

Practical information
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. When the engine is running, disconnect the leads in reverse or- der to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 182.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
WARNING (Continued)
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
● The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not bend over the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected. 
