2016 Seat Mii sensor

Operation
●
Alw a
ys observe the area around the vehi-
cle, as the sensors do not always detect
small children, animals or objects.
● The surface of certain objects and some
clothing do not
reflect the ultrasound signals
from the parking distance system. The sys-
tem cannot detect or incorrectly detects
these objects and people wearing these
types of clothes.
● External sound sources can affect the park-
ing dis
tance aid signals. In this case, under
certain circumstances, people and objects
will not be detected. CAUTION
● The sensor s

may not always be able to de-
tect objects such as trailer draw bars, thin
rails, fences, posts, trees and open boots,
etc. This could result in damage to your car.
● Although the parking distance warning sys-
tem detect
s and warns of the presence of an
obstacle, the obstacle could disappear from
the angle of measurement of the sensors if it
is too high or low and the system would no
longer show it. Therefore, it will not warn you
of these objects. Ignoring the warnings of the
parking sensor system could cause consider-
able damage to the vehicle.
● The bumper sensors may become damaged
or misa
ligned, for example, when parking.
● To ensure that the system works properly,
the bumper sensor
s must be kept clean, free
of ice and snow and uncovered. ●
When cl e

aning the sensors with high-pres-
sure or steam cleaning equipment, spray the
sensors briefly at a distance of no less than
10 cm.
● Different sources of noise can produce er-
rors
in the parking distance warning system,
e.g. parking distance warning systems from
other vehicles, inductive loops or construc-
tion works machines.
● Retrofitting of components to the vehicle,
such a
s a bicycle carrier, may interfere with
the function of the parking distance warning
system. Parking distance warning system

Special features of the parking distance
warning system
● The parking distance warning system
sometimes r
egisters water on the sensors as
an obstacle.
● If the distance does not change, the warn-
ing sign
al will sound less loudly after a few
seconds. If the continuous signal sounds, the
volume will remain constant.
● When the vehicle moves away from the ob-
stac
le, the beeping sound automatically
switches off. When getting close again, it re-
connects.
● Your SEAT dealership can adjust the volume
of the warnin
g signals. Note

Any r

epair of the laser sensor requires spe-
cialised skills. SEAT recommends taking 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.

Safety

Operation
The City Safety Assist function is limited by
the l a
w
s of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the laser sensor
detects a vehicle travelling in the adjoining
lane ››› Fig. 156 A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 156 B. This applies especial-
ly to narrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 157. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch. Possible malfunction to the laser sensor
If the la
ser sensor operation function is im-
paired, for example due to heavy rain, mist,
snow or dirt, the City Safety Assist system
function is temporarily disconnected. On the
instrument panel display the control lamp 
flashes.
When the malfunction in the laser sensor has
been rectified, the availability of the City
Safety Assist system function is automatically
restored. The control lamp  switches off.
The following conditions could prevent the
City Safety Assist system from functioning:
● Tight bends.
● Accelerator pressed all the way down to the
floor.
● If the C

ity Safety Assist system is switched
off or there i
s a fault ››› page 157.
● If the laser sensor is dirty, covered or over-
heated ›

›› page 158.
● In the event of snow, heavy rain or dense
fog.
● If ther

e are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● V

ery dirty vehicles with a low degree of re-
flection.
● Pr e

sence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
The hi l

l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral f

or manual gear change and with the
selector lever at positions S, D or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill.

Advice
●
All
repairs and modifications to the vehicle
should only be performed by a specialised
workshop. Repairs and malfunctions in the air-
bag sy
s

tem When performing repairs and technical mod-
ification
s,

SEAT's directives must be ob-
served! ››› Modifications and repairs to the front bump-
er
, door
s, fr

ont seats, and repairs to the roof
or chassis should only be carried out in a
specialised workshop. These components
may contain parts or sensors belonging to
the airbag system.
If work is carried out on the airbag system or
parts have to be removed and fitted on the
system when performing other repair work,
parts of the airbag system may be damaged.
The consequence may be that, in the event of
an accident, the airbag inflates incorrectly or
does not inflate at all.
So that the effectiveness of the airbag is not
reduced and that removed parts do not cause
any injuries or environmental pollution, regu-
lations must be observed. These require-
ments are known to specialised workshops.
Modifications to the vehicle suspension may
affect the operation of the airbag system in
the event of collision. For example, if wheel and tyre combinations not approved by SEAT
are used, or if

the vehicle height is lowered,
the suspension is stiffened or the suspension
springs, telescopic arms, dampers, etc., are
modified, the results received by the airbag
sensors and sent to the control unit may not
be accurate. For example, some modifica-
tions to the suspension could increase the
force measured by the sensors and result in
the triggering of the airbag systems in colli-
sions. Under normal conditions, the meas-
ured values would be lower and the airbag
would not have been triggered. Other modifi-
cations may reduce the forces measured by
the sensors and prevent the airbags from be-
ing triggered when they should. WARNING
Repairs or modifications which are not per-
formed c orr

ectly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the airbag systems. This could
result in serious or fatal accidents.
● All repairs and modifications to the vehicle
should on
ly be performed by a specialised
workshop.
● Airbag modules must never be repaired: if
damag
ed, they must be replaced.
● Never fit recycled or reused airbag compo-
nents in
your vehicle. WARNING
Modifications to the vehicle suspension, in-
cludin g the u

se of unauthorised wheel and
tyre combinations, may affect the perform-
ance of the airbags and increase the risk of
serious or fatal injury in the event of acci-
dent.
● Never fit suspension components which are
not identica
l to the original parts in the vehi-
cle.
● Never use wheel and tyre combinations not
appro
ved by SEAT. Retrofitting of mobile phones
An exterior aerial is required for the use of
tw
o-w
a

y radios in the vehicle.
The retro-fitting of electrical or electronic ap-
pliances in the vehicle is subject to their ap-
proval for use in your vehicle. Under certain
circumstances, this could mean that your ve-
hicle registration documents are no longer
valid.
SEAT has approved your vehicle for use with
two-way radios providing the following condi-
tions are observed:
● The exterior aerial must be mounted pro-
fes
sionally.
● The maximum transmitting power is 10
watts.
166

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 ››› .
K eep a s uit

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
seals could freeze! Cleaning windows and exterior mir-
