Seat Mii 2016 Service Manual

The essentials
●
Only u
se wheel bolts which correspond to
the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free
of oil
and grease and easy to thread.
● To loosen and tighten the wheel bolts, al-
way
s use the wheel brace supplied with the
vehicle.
● Loosen the wheel bolts only about one turn
before r
aising the vehicle with the jack.
● Never grease or lubricate wheel bolts or the
wheel hub thre
ads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● If the wheel bolts are not tightened to the
correct
torque, they may come loose while
driving, and the bolts and rims may come
out. If the tightening torque is too high, the
wheel bolts and threads can be damaged. Raising the vehicle with the jack

The essentials
WARNING
If the vehicle is not correctly raised, it could
fa l
l off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT f
or your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground i
s sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
plac
e a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The c
law of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 56.
● You should never place a body limb such as
an arm or leg u
nder a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine i
s running.
● Never start the engine when the vehicle is
raised.
The vehicle may come loose from the
jack due to the engine vibrations. Removing and fitting a wheel

Removing the wheel
● Slacken the wheel bolts ›››
page 38.
● Raise the vehicle ›››
page 39.
● Using the hexagonal socket in the wheel
brace ›

›› Fig. 57, unscrew the slackened
wheel bolts and place them on a clean sur-
face.
● Take off the wheel.
How to u
se the spare wheel or temporary
spare wheel
Check the direction of rotation of the tyre
›››  page 207, Tyre code. ●
Place the s
pare wheel or temporary spare
wheel into position.
● Replace the wheel bolts and tighten slight
-
ly using the hexagonal socket on the end of
the wheel brace.
● To tighten the anti-theft locking wheel bolts
use the corr
esponding adaptor.
● Lower the car with the jack.
● Tighten all of the wheel bolts clockwise
›››
. Tighten the bolts in diagonal pairs (not
in a c ir
c
le).
● Put the caps, trim or full hubcap back on
›››
page 37. WARNING
If the wheel bolts are not treated suitably or
not tight ened t

o the correct torque then this
could lead to loss of vehicle control and to a
serious accident.
● All the wheel bolts and hub threads should
be cle
an and free of oil and grease. The wheel
bolts should be easily tightened to the cor-
rect torque.
● The hexagonal socket in the wheel brace
should be u
sed for turning wheel bolts only.
Do not use it to loosen or tighten the wheel
bolts. 40

The essentials
Tyres with compulsory direction of ro-
t ation A directional tread pattern can be identified
by
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.
After the wheel change ●
Clean the vehicle tools, if necessary and
p ut
them a

way in the luggage compartment
foam holder ›››
 page 70.
● Store the spare wheel, the temporary spare
wheel or the ch
anged wheel securely in the
luggage compartment. ●
Have the tightenin
g torque of the wheel
bolts checked as soon as possible with a tor-
que wrench ››› page 38.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use When using snow chains, applicable local
l
e
gi

slation and maximum permitted speed
limits must be observed.
In winter weather, snow chains not only help
to improve grip but also improve the braking
capacity.
The fitting of chains is permitted only on
front wheels and with the following combi-
nations of wheel trims and tyres :
Tyre sizeWheel rim
165/70 R145 J x 14 offset of 35175/65 R14 SEAT recommends you ask a technical serv-
ic
e f
or f

urther information on wheel, tyre and
chain sizes.
Wherever possible use fine-link chains meas-
uring less than 15 mm including the lock. Remove wheel hub covers and trim rings be-
fore fittin

g snow chains ››› . The wheel bolts
shou l
d be c
overed with caps for safety rea-
sons. These are available from technical serv-
ices.
Temporary spare wheel
For technical reasons, snow chains must not
be used on the compact temporary spare
wheel ›››
 page 206.
If it is necessary to fit chains with the tempo-
rary spare wheel in use, install the wheel on
the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, in-
stead of the damaged front wheel. In this sit-
uation, observe the rotating direction of the
wheels. SEAT recommends attaching the
snow chains before fitting the wheel. WARNING
The use of unsuitable or incorrectly fitted
ch ain

s could lead to serious accidents and
damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by
the snow c
hain manufacturer.
● Never exceed the maximum permitted
speeds
when driving with snow chains. » 41

The essentials
CAUTION
● Remo v
e the snow chains to drive on roads
without snow. Otherwise they will impair
vehicle handling, damage the tyres and wear
out very quickly.
● Wheel rims may be damaged or scratched if
the chain
s come into direct contact with
them. SEAT recommends the use of covered
snow chains. Note
Snow chains are available in different sizes
acc or

ding to the vehicle type. Emergency towing of the vehi-

›››  page 70.
Screw the front towline anchorage into the
screw connection ››› Fig. 58 and tighten it
with the wheel brace.
Tow rope or tow bar
When towing, the tow bar is the safest and
vehicle friendly way. You should only use a
tow rope if you do not have a tow bar. A tow rope should be slightly elastic to avoid
damag

e to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
● Only secure the tow rope or tow bar to the
towline anc
horage or specially designed fit-
ting.
Notes for the driver of the towed vehicle
● Keep the ignition running to prevent the
steerin
g wheel from locking and also to allow
the use of the turn signals, horn, windscreen
wipers and washers.
● As the power assisted steering does not
work if
the engine is not running, you will
need more strength to steer than normally.
● The brake must be depressed much harder
as the br
ake servo does not operate. Avoid
hitting the towing vehicle.
● Note the instructions and information con-
tained in the Ins
truction Manual for the vehi-
cle to be towed.
Notes for the driver of the towing vehicle
● Accelerate gently and carefully. Avoid sud-
den manoeuvr
es.
● Brake well in advance than usual and brake
gently.
● Not

e the instructions and information con-
tained in the In s

truction Manual for the vehi-
cle to be towed. 42

The essentials
Driving style
T o
w
ing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow.
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times. ››› in Instructions for tow-starting on
page 76
››› page 75 Tow-starting
In general, the vehicle should not be started
by
t

owing. Jump-starting is much more pref-
erable ››› page 43.
For technical reasons, the following vehicles
can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible
that the en

gine control unit does not operate
correctly.
However, if your vehicle must absolutely be
tow-started (manual gearbox):
● Put it into second or third gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Rel

ease the clutch when both vehicles are
movin
g.
● As soon as the engine starts, press the
clutc
h and move the gear lever into neutral.
This helps to prevent a collision with the tow-
ing vehicle. How to jump start
Jump lea
ds If the engine fails to start because of a dis-
ch
ar

ged battery, the battery of another vehi-
cle can be used to start the engine. Before
starting, check the magic eye on the battery
›››  page 196.
For starting assistance, jump lead cables con-
forming to the standard DIN 72553 are re-
quired (see the cable manufacturer instruc-
tions). The cable section in vehicles with pet-
rol engine must be at least 25 mm 2
. WARNING
Incorrect use of jump leads and incorrectly
jump st ar

ting could cause the battery to ex-
plode resulting in serious injury. Please ob-
serve the following rules to minimise the risk
of a battery explosion:
● The battery providing current must have
the same v
oltage (12V) and approximately
the same capacity (see markings on battery)
as the flat battery.
● Never charge a frozen or recently thawed
batter
y. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
● If a battery is frozen and/or has been frozen
then it mus
t be replaced.
● A highly explosive mixture of gases is re-
lea
sed when the battery is being charged. Al-
ways keep lit cigarettes, flames, sparks and » 43

The essentials
fire far from the battery. Never use a mobile
tel
ephone when c
onnecting and removing the
jump leads.
● Charge the battery only in well ventilated
area
s given that when the battery is charged
by outside assistance, it creates a mix of
highly explosive gases.
● Jump leads should never enter into contact
with mov
ing parts in the engine compart-
ment.
● Never switch the positive and negative
pole
s or connect the jump leads incorrectly.
● Note the instruction manual provided by
the manufact
urer of the jump leads. CAUTION
To avoid considerable damage to the vehicle
electric a

l system, note the following careful-
ly:
● If the jump leads are incorrectly connected,
this c
ould result in a short circuit.
● The vehicles must not touch each other,
otherwi
se electricity could flow as soon as
the positive terminals are connected. How to jump start: description

The essentials
8. Start the engine of the vehicle with the flat batt
er
y and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped be
am headlights (if they
are switched on).
10.Turn on the heater blower and heated rear window in the
vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.
When the engine is running, disconnect
the leads in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery termi-
nals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 186.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint on battery). Failure to comply could result in
an exp
lo

sion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter 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
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le 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 vehic
le to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the wiper blades
