2017 Seat Mii brakes

Driver assistance systems
●
Any r
eparation of the laser sensor requires
specialist knowledge. SEAT recommends tak-
ing your car in for technical service. Note
● If the C ity

Safety Assist function activates a
brake, the brake pedal range is reduced. This
makes the brake pedal seem “harder”.
● Automatic brake intervention by the City
Safety As
sist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assi
st function you may hear unusual noises.
This is normal and is produced in the brake
system. Warning and control lamp

waste. Observe information provided by the
manuf
act
urer. Washing the vehicle
The longer substances such as insects, bird
drop
pin

gs, resinous tree sap, road dirt, in-
dustrial deposits, tar, soot or road salt and
other aggressive materials remain on the ve-
hicle, the more damage they do to the paint-
work. High temperatures (for instance due to
strong sunlight) further intensify the corro-
sive effect. The vehicle undercarriage should
also be thoroughly washed at regular inter-
vals.
Automatic car washes
Always observe the instructions provided at
the automatic car wash. The standard pre-
cautionary measures prior to entering the car
wash should be taken to avoid damage to
the vehicle (close all windows and the roof,
fold in exterior mirrors). If the vehicle is fitted
with additional components (spoiler, roof-
rack, aerial, etc.), check with the car wash su-
pervisor whether these can enter the car
wash ››› .
The v
ehic

le paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, wear and damage to the paintwork
will depend on the type of car wash used. SEAT recommends the use of car washes
without bru

shes.
To remove traces of wax on windows and to
prevent wiper blades from scratching, please
observe the following ››› page 172, Cleaning
windows and exterior mirrors .
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
Start at the roof and work downwards. Spe-
cial car shampoo should only be used for
very persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
Sharp components on the vehicle may cause
injury .
● Pr

otect arms and hands from sharp edges
when cle
aning the vehicle undercarriage or
the interior of the wheel hubs. WARNING
After the vehicle has been washed, the brak-
ing eff ect

will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The wat er t

emperature should not exceed
+60°C (+140°F).
● To avoid damage to the paintwork, do not
wash the
vehicle in full sun.
● Do not use rough sponges or similar which
coul
d damage the surface to clean away the
traces of insects.
● Never wipe the headlights with a dry cloth
or spong
e, always moisten first. It is best to
use soapy water.
● Washing the vehicle in low temperatures:
When washin
g the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and
seals could freeze! CAUTION
To avoid any risk of damage to the vehicle,
pl e

ase check the following points before us-
ing an automatic car wash: » 171

Advice
●
Comp ar
e the distance between the vehicle
wheels and the distance between the guide-
rails of the car wash to prevent damage to the
wheels and tyres!
● Switch off the rain sensor before taking the
vehicl
e to an automatic car wash.
● Compare the height and width of your vehi-
cle w
ith the available height and width when
entering and driving through the car wash.
● Fold in exterior mirrors Electrically retracta-
ble e
xterior mirrors must not be folded in or
out by hand. Always use the electrical power
control.
● To avoid damaging the bonnet paintwork,
res
t the windscreen wipers on the windscreen
after drying the wiper blades. Do not let them
fall!
● Lock the rear lid to prevent it from opening
unexpect
edly while inside the car wash. Washing the vehicle with a high pres-
s
ur
e c

leaner When cleaning the vehicle with a high-pres-
s
ur
e c

leaner, always follow the operating in-
structions for the equipment. Pay special at-
tention to the required pressure of the jet
and the distance between the jet and the ve-
hicle ››› .

able distance from soft materials,
such as rubber hoses or insulating material,
and from the parking distance warning sys- tem sensors. The sensors of the parking dis-
tance w

arning system are situated on the rear
bumper ››› .
Do not u
se a no

zzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt ››› .
WARNING
The incorrect use of high pressure cleaning
equipment c ou

ld result in permanent dam-
age, visible or invisible, to the tyres or other
materials. This could result in a serious acci-
dent.
● Ensure there is a suitable distance between
the nozzl
e and the tyres.
● Never wash tyres with a concentrated jet or
so-cal
led “dirt blasters”. Even at large spray-
ing distances and short cleaning times, you
may damage the tyres. WARNING
After the vehicle has been washed, the brak-
ing eff ect

will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The wat er t

emperature should not exceed
+60°C (+140°F).
● To avoid damage to the paintwork, do not
wash the
vehicle in full sun.
● To ensure that the system functions well,
the sensors
located on the bumper must be
kept clean and free from ice. When cleaning
with pressure hoses and steam cleaners, the
sensors should be sprayed only briefly. A dis-
tance of 10 cm between the sensors and the
steam / hose nozzle must be observed.
● Do not use a high pressure cleaner to re-
move ic
e or snow from windows
● Washing the vehicle in low temperatures:
When washin
g the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and

Advice
●
When refi l
ling liquids, avoid spilling them
on parts of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. Under
specific circumstances, the ethylene glycol
can catch fire. WARNING
If there is not enough anti-freeze in the cool-
ant sys

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the cool
ant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
● If ther e i

s no appropriate coolant liquid
available, fill it using distilled water, and
nothing else. Any other type of water may
lead to considerable rusting in the engine
due to its chemical components. This could
consequently damage the engine. If you have
not used distilled water but another type of
water to top up the coolant, a specialised
workshop must immediately replace all of the
fluid in the engine cooling system.
● Only top up coolant to the top level of the
marked ar
ea ››› Fig. 170. Otherwise the ex- cess coolant will be forced out of the cooling
sys
t

em when the engine is hot, causing dam-
age.
● If a lot of liquid coolant has been lost, wait
for the engine t
o cool down completely before
adding coolant. Extensive coolant loss is an
indication of leaks in the engine cooling sys-
tem. Have the engine cooling system inspec-
ted immediately by a specialised workshop.
Otherwise engine damage may occur.
● When refilling service liquids, ensure that
you put
the liquids into the right tank. Mak-
ing a mistake when refilling could cause seri-
ous malfunctions and damage the engine! CAUTION
The original additives should never be mixed
with c oo

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
ut is, for example, brown, this indicates
that the G13 additive has been mixed with an
inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. Brake fluid

In the course of time, the brake fluid absorbs
water from the ambient air. If there is too
much water in the brake fluid, the brake sys-
tem could be damaged. In addition, the boil-
ing point of the brake fluid is significantly
lowered. When the brake fluid contains too
much water and the brakes are subject to
considerable forces, bubbles of water vapour
can form in the system. These bubbles can
significantly reduce braking power, notably
increasing braking distance, and could even
result in the total failure of the brake system.
Ensuring that the brake system is always
functioning correctly is essential for your own
safety and the safety of other road users

pecifications
SEAT have developed a special brake fluid
optimised for the brake systems of their vehi-
cles. To ensure the optimum working of the
brake system, SEAT recommends the use of
brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or
another brake fluid is used for different rea-
sons, use a brake fluid that complies with the
United States standard FMVSS 116 DOT 4 or
194

Checking and refilling levels

.
Br ak
e fluid
s conforming to the standard
VW 501 14, fulfil the American requirements
of the FMVSS 116 DOT 4 standard and the
German DIN ISO 4925 CLASS 4 standard.
However, fluids that comply with the Ameri-
can FMVSS 116 DOT 4 standard or the Ger-
man DIN ISO 4925 CLASS 4 standard do not
necessarily comply with the VW 501 14
standard. Always check the information on
the brake fluid container and ensure that you
are using suitable brake fluid.
A suitable brake fluid can be obtained from
SEAT dealerships.
Brake fluid level
The level of the brake fluid should always be
between the MIN and MAX marks, or above
the MIN mark ››› .
It i
s

not always possible to check the level of
the brake fluid, as in some models the en-
gine components make it difficult to see the
brake fluid reservoir. If you cannot read the
exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the
vehicle is being used due to wear of the
brake pads and the automatic readjustment
of the brake. Changing the brake fluid
The brake fluid shou

ld be changed in accord-
ance with the instructions given in the Main-
tenance Programme. Have the brake fluid
changed by a specialised workshop. SEAT
recommends taking your car in for technical
service. This means that only brake fluid
complying with the required specifications
will be used. WARNING
If the brake fluid level is low or unsuita-
bl e/o

ld brake fluid is used, the brake system
may fail or braking power may be reduced.
● Check the brake system and the brake fluid
level
regularly!
● The brake fluid should be changed regular-
ly in acc
ordance with the instructions given
in the Maintenance Programme.
● Always ensure that you use suitable brake
fluid. Only u
sed brake fluid that conforms to
the VW 501 14 standard, FMVSS 116 DOT 4
standard or even the DIN ISO 4925 CLASS 4
standard. Other types of brake fluid could af-
fect brake operation and reduce braking pow-
er. Do not use a brake fluid if the container
does not specify compliance with the
VW 501 14, FMVSS 116 DOT 4 or
DIN ISO 4925 CLASS 4 standards.
● The replacement brake fluid must be new.
● Brake fluid should be stored in the closed
original
container in a safe place out of reach
of children. Risk of poisoning! ●
If the br ak

e fluid is left in the system for
too long and the brakes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
W ipe off an

y brake fluid from the paintwork
immediately. For the sake of the environment
Brake fluid is an environmental pollutant.
