Radar sensor detection area. A radar sensor on the windscreen
››› Fig. 88
allows the system to detect driving situations
in front of the vehicle.
Vehicles ahead can be detected up to a dis-
tance of about 10 m. WARNING
The laser beam on the radar sensor can pro-
duce serious injuries to the eyes.
● Never focus optical devices, e.g. a camera,
a microscope or a magnifying glass closer
than 100 mm from the radar sensor.
● Note that the laser beam can stay active
when the City Safety Assist system is switch-
ed off or unavailable. The laser beam is not
visible to the human eye. CAUTION
If the windscreen is dirty or frosted in the
area of the radar sensor, e.g. due to rain, mist or snow, the City Safety Assist system may
fail to operate as a result.
● Always keep the radar sensor area free of
dirt and frost.
● Use a small brush to remove snow and a
de-icer spray to remove ice. CAUTION
A damaged windscreen in the radar sensor
area may cause the City Safety Assist func-
tion to fail to operate.
● Replace the windscreen if it is scratched,
cracked or chipped by stones in the radar
sensor area. Only use a windscreen author-
ised by SEAT. Carrying out repairs is not per-
mitted (e.g. in the case of damage suffered in
an impact from a stone).
● When replacing the windscreen wipers, on-
ly use windscreen wipers authorised by SEAT.
● Do not paint the radar sensor area on the
windscreen, or cover it with adhesives or oth-
er materials. 112

Advice
Operation
Safety

Operation
The City Safety Assist function is limited by
the laws 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 radar sen-
sor detects a vehicle travelling in the adjoin-
ing lane ››› Fig. 91
A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The radar sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 91 B. This applies especially
to n

arrow 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. 92. To inter-
rupt dec

eleration you can accelerate, turn the
steering wheel or press the clutch. Malfunction in the radar sensor
If the radar sensor operation is impaired, for
example due to heavy rain, mist, snow or dirt,
the City Safety Assist system function is tem-
porarily switched off. On the instrument pan-
el display the control lamp
 flashes.
When the fau

lt in the radar sensor has been
rectified, the City Safety Assist system func-
tion automatically becomes available. 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 City Safety Assist system is switched
off or there is a fault ››› page 111.
● If the radar sensor is dirty, covered or over-
heated ››› page 112.
● In the event

of snow, heavy rain or dense
fog.
● If there are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● Very dirty vehicles with a low degree of re-
flection.
● Presence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
The hill 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 for 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. Repair and faults in the airbag system
When performing repairs and technical mod-
ifications, SEAT's directives must be ob-
served!
››› Modifications and repairs to the front bump-
er, doors, front 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 correctly 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 only be performed by a specialised
workshop.
● Airbag modules must never be repaired: if
damaged, they must be replaced.
● Never fit recycled or reused airbag compo-
nents in your vehicle. WARNING
Modifications to the vehicle suspension, in-
cluding the use 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 identical to the original parts in the vehi-
cle.
● Never use wheel and tyre combinations not
approved by SEAT. Retro-fitting of two-way radios
An exterior aerial is required for the use of
two-way 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-
fessionally.
● The maximum transmitting power is 10
watts.
The optimal reach of the equipment is only
achieved with an external aerial.

Care and maintenance
SEAT recommends the use of car washes
without brushes.
To remove traces of wax on windows and to
prevent wiper blades from scratching, please
observe the following ››› page 128, 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
ver

y 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.
● Protect arms and hands from sharp edges
when cleaning the vehicle undercarriage or
the interior of the wheel hubs. WARNING
After the vehicle has been washed, the brak-
ing effect 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
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The temperature of the water must not ex-
ceed +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
could damage the surface to clean away the
traces of insects.
● Never wipe the headlights with a dry cloth
or sponge, always moisten first. It is best to
use soapy water.
● Washing the vehicle in low temperatures:
When washing 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 prevent damage to the vehicle, please ob-
serve the following before entering an auto-
matic car wash: ●
Compare 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
vehicle to an automatic car wash.
● Compare the height and width of your vehi-
cle with the available height and width when
entering and driving through the car wash.
● Fold in exterior mirrors Electrically retracta-
ble exterior mirrors must not be folded in or
out by hand. Always use the electrical power
control.
● To avoid damaging the bonnet paintwork,
rest 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
unexpectedly while inside the car wash. Washing the vehicle with high
pressure cleaning apparatus
When cleaning the vehicle with a high-pres-
sure cleaner, 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-
hic

le ››› .
Keep a suitable 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 warning system are situated on the rear
bumper ››› .
Do not use a nozzle that sprays the water out
in a direct stream
or one th
at has a rotating
jet for forcing off dirt ››› .
WARNING
The incorrect use of high pressure cleaning
equipment could 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 nozzle and the tyres.
● Never wash tyres with a concentrated jet or
so-called “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 effect 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
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The temperature of the water must not be
above +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 ice or snow from windows
● Washing the vehicle in low temperatures:
When washing 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
mirrors
Cleaning windows and exterior mirrors
Spray windows and exterior windows with a
standard window cleaner containing alcohol.
Dry the windows with a clean chamois leath-
er or a lint-free cloth. The chamois leathers
used on painted surfaces are not suitable for
cleaning windows because they are soiledwith wax deposits which could smear the
windows.
Use window cleaner or a silicone remover to
clean rubber, oil, grease and silicone depos-
its off
››› .
Removing wax deposits
Automatic car washes and certain car care
products may leave wax deposits on the win-
dows. These deposits can only be removed
with a special product or cleaning cloths. If
wax deposits are left on the windscreen and
the rear window, the blades can scratch the
glass. SEAT recommends you wipe the wax
deposits off the windscreen and the rear win-
dow with a soft cloth each time after you
have washed the vehicle.
A window cleaning detergent which helps to
dissolve the wax may be added to the wind-
screen washer fluid to prevent the wiper
blades from scratching the windscreen.
Please ensure you add the cleaning product
in the correct proportions. Products for re-
moving grease do not eliminate the wax de-
posits ››› .
Special cleaning products or window cloths
are available at any technical service. To re-
move wax deposits, SEAT recommends the
following products:

Care and maintenance
Labels and plates Fig. 100
Warnings relating to handling the
City Safety Assist system radar sensor func-
tion Some parts in the engine compartment come
from the factory with certificates of safety, la-
bels or plates containing important informa-
tion regarding the operation of the vehicle,
for example, on the petrol cap, on the pas-
senger's sun visor, on the driver door strut, or
on the floor of the boot.
● Never remove these certificates of safety,
labels or plates, and ensure they are kept in
good condition and are legible.
● If a vehicle part, bearing a certificate of
safety, label or plate, is replaced, the special-
ised workshop should attach the information
back in the same place. Certificate of safety
A certificate of safety on the door strut states
that all the safety standards and regulations
established by the national traffic authorities
responsible for road safety were met at the
time of manufacture. It may also give the
month and year of manufacture, together
with the chassis number.
Warning of high voltage label
There is a label close to the bonnet lock
which warns of high voltage in the vehicle's
electrical system.
Warning relating to the City Safety Assist
system laser sensor
There are some warning and information
signs on the City Safety Assist system laser
sensor
››› Fig. 100 .
U s
ing your vehicle in other countries
and continents The vehicle is manufactured at the factory for
use in a particular country in accordance with
the national legislation in force at the time of
manufacture.
If the vehicle is sold in another country or
used in another country for an extended peri-
od of time, the applicable legislation of that
country should be observed.It may be necessary to fit or remove certain
pieces of equipment or to deactivate certain
functions. Service work may also be affected.
This is particularly true if the vehicle is used
in a different climate for an extended period
of time.
As there are different types of frequency
bands around the world, you may find that
the radio system or the Portable Navigation
System (supplied by SEAT) supplied at the
factory does not work in another country.
CAUTION
● SEAT does not accept liability for any dam-
age to the vehicle due to the use of a lower
quality fuel, an inadequate service or the
non-availability of genuine spare parts.
● SEAT does not accept liability if the vehicle
does not comply in part or in full with the le-
gal requirements of other countries or conti-
nents. Radio reception and the aerial
For factory-fitted radio equipment, the aerial
for radio reception is fitted to the roof of the
vehicle.
