Operation
●
It i s
dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a c
onstant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Safety Assist* (City Safety As-
si
s

t function)
Introduction The City Safety Assist function covers driving
s
it
uation

s at a distance of about 10 metres in
front of the vehicle, in a speed range of ap-
proximately 5-30 km/h (3-19 mph).
When the system detects a possible collision
with a vehicle in front, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er doe

s not react to an imminent
collision, the system can automatically brake
the vehicle in order to reduce speed faced
with a possible collision. The system can
help to reduce the consequences of an acci-
dent.
If the City Safety Assist function determines
that the driver has braked insufficiently when
faced with an imminent collision, the system can increase the brake force in order to re-
duce speed.

The system can help to reduce
the consequences of an accident. WARNING
The smart technology in the City Safety As-
si s

t system cannot change the limits imposed
by the laws of physics and by the system it-
self. The increased convenience offered by
the City Safety Assist system should never
prompt you to take risks. The driver always
assumes the responsibility of braking in
time.
● The City Safety Assist function cannot pre-
vent ac
cidents or serious injury by itself.
● The City Safety Assist system may carry out
unw
anted brake interventions in complex
driving situations e.g. when a vehicle crosses
at a short distance. WARNING
Relying on the City Safety Assist system in
city driv

ing as part of one's driving behaviour
may cause accidents and serious injury. The
system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance
to the v
ehicles 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 peop
le, animals or vehicles that cross or move in the opposite direction in the same
lane.
●
If af

ter 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-
d ar f e

ature is damaged, switch it off. This will
avoid additional damage.
● Any repair of the radar sensor requires spe-
cia
list knowledge. 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.
● 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. 152

Other vehicles changing lanes 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 radar sen-
sor detects a vehicle travelling in the adjoin-
ing lane ››› Fig. 153 A. To interrupt decelera-
tion 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. 153 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. 154. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch. Malfunction in the radar sensor
If the ra
dar 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 fault 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 C

ity Safety Assist system is switched
off or there i
s a fault ››› page 153.
● If the radar sensor is dirty, covered or over-
heated ›

›› page 153.
● 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.
● Pre

sence of thick dust.
