Driver assistance systems
system is not a replacement for driver aware-
ness.
●
Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● The City Safety Assist function does not re-
act to people, animals or vehicles that cross
or move in the opposite direction in the same
lane.
● If after switching on the City Safety Assist
function the vehicle begins to move, slow the
vehicle with the foot brake. CAUTION
If you suspect that the City Safety Assist ra-
dar feature is damaged, switch it off. This will
avoid additional damage.
● Any repair of the radar sensor requires spe-
cialist knowledge. SEAT recommends taking
your car in for technical service. Note
● If the City 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 Assist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assist function you may hear unusual noises. This is normal and is produced in the brake
system.
Warning and control lamps
The City Safety Assist function is switched on
every time the ignition is switched on. No
special indication is produced.
If the City Safety Assist function is switched
off or on, or if there is an error in the system,
it will be shown by a control lamp on the in-
strument panel display.It lights

Operation
WARNING
If the warning lamps are ignored, the vehicle
may stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps when they
appear may result in faults in the vehicle. Radar sensor
Fig. 88
In the windscreen: City Safety Assist
function radar sensor. Fig. 89
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

● After the radar sensor has been involved in
a collision.
● When driving off road (overhanging branch-
es).
● If objects are protruding above the bonnet,
e.g. a load carried on the roof that signifi-
cantly protrudes over the front.
● If the windscreen is damaged in the radar
sensor area. WARNING

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.
