Driver assistance systems
Parking sensor system*
Introduction
The parking sensor system assists the driver when parking. If the rear of the
vehicle is approaching an obstacle, an intermittent audible warning is emit-
ted. The shorter the distance, the shorter the intervals between tones. If the
vehicle is too close to the obstacle, the audible warning becomes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
Sensors situated on the rear bumper transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacles and re-
ception), this system continuously calculates the distance between the
bumper and the obstacle.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The parking distance warning system cannot replace the driver's assess-
ment of the situation.
● The sensors have blind spots in which obstacles and people are not
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
WARNING (Continued)
● The surface of certain objects and some clothing do not reflect the ul-
trasound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these
types of clothes.
● External sound sources can affect the parking distance aid signals. In
this case, under certain circumstances, people and objects will not be de-
tected.
CAUTION
● The sensors may not always be able to detect objects such as trailer
draw bars, thin rails, fences, posts, trees and open luggage compartments,
etc. This could result in damage to your car.
● Although the parking sensor system detects and warns of the presence
of an obstacle, the obstacle could disappear from the angle of measure-
ment of the sensors if it is too high or low and the system would no longer
indicate it. Therefore, it will not warn you of these objects. Ignoring the
warnings of the parking sensor system could cause considerable damage to
the vehicle.
● The bumper sensors may become damaged or misaligned, for example,
when parking.
● To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray the sensors briefly at a distance of no less than 10 cm.
● Different sources of noise can produce errors in the parking distance
warning system, e.g. parking distance warning systems from other vehicles,
inductive loops or construction works machines.
● Retrofitting of components to the vehicle, such as a bicycle carrier, may
interfere with the function of the parking distance warning system. 

Parking distance warning system
Fig. 96 Parking distance
warning system sensors
on the rear bumper
The 3 sensors of the parking distance warning system are situated on the
rear bumper ⇒ Fig. 96. Switching the parking sensor system on and off
● Switching on: With the ignition switched on, select reverse gear. A short
audible warning confirms that the parking distance warning system is
switched on and functioning.
● Switching off: release reverse gear.
Things to note on the parking distance warning system
● The parking sensor system sometimes registers water on the sensors as
an obstacle.
● If the distance does not change, the warning signal will sound less loud-
ly after a few seconds. If the continuous signal sounds, the volume will re-
main constant.
● When the vehicle moves away from the obstacle, the beeping sound au-
tomatically switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
● Your SEAT dealership can adjust the volume of the warning signals.
Note
A fault in the parking distance warning system is indicated through a brief
audible warning that is constant for about 3 seconds when switching on for
the first time. Check the parking distance warning system at a Specialised
workshop as soon as possible. 

Cruise control* (Cruise control system - CCS)
Introduction
The cruise control system (CCS) is able to individually maintain the set
speed when driving forwards from approx. 20 km/h (15 mph).
The CCS only slows down by reducing the accelerator but not by braking
⇒ 
.
Additional information and warnings:
● Changing gear ⇒ page 124
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the cruise control in heavy traffic, if the distance from the
vehicle in front is insufficient, on steep roads, with several bends or in
slippery circumstances (snow, ice, rain or loose gravel), or on flooded
roads.
● Never use the CCS when driving off-road or on unpaved roads.
● 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.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
● It is 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 constant
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 Assist function) Introduction
The City Safety Assist function covers driving situations at a distance of
about 10 metres in front of the vehicle, in a speed range of approximately
5-30 km/h (3-19 mph).
When the system detects a possible collision with a vehicle in front, the ve-
hicle prepares for a possible emergency braking ⇒ 
.
If the driver does not react to an imminent collision, the system can auto-
matically brake the vehicle in order to reduce speed faced with a possible
collision. The system can help to reduce the consequences of an accident.
If the City Safety Assist function determines that the driver braked insuffi-
ciently faced with an imminent collision, the system can increase the brake
force in order to reduce speed. The system can help to reduce the conse-
quences of an accident.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Centre console, lower section ⇒ page 12
● Instrument panel ⇒ page 15
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The intelligent technology in the City Safety Assist system cannot change
the limits imposed by the laws of physics and by the system itself. The
increased comfort 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 can not individually prevent accidents,
nor serious injury.
● The City Safety Assist system may carry out unwanted brake interven-
tions in complex driving situations e.g. when a vehicle crosses at a short
distance.
WARNING
Including the role of the City Safety Assist system in driving conduct may
cause accidents and serious injury. The system is not a replacement for
driver awareness.
● 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 react 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 laser sensor of the City Safety Assist function is dam-
aged, switch off the City Safety Assist function. This will avoid additional
damage.
● Any reparation of the laser sensor requires specialist knowledge. SEAT
recommends visiting a 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”.
Note
Automatic brake intervention by the City Safety Assist function can be can-
celled by pressing the clutch pedal, the accelerator pedal or by a corrective
intervention.
Note
During the automatic braking by the City Safety Assist function you may
hear unusual noises. This is normal and is produced in the brakes 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, functions or there is an error
in the system, this will be shown by a control lamp on the instrument panel
display.

detection area
A laser sensor on the windscreen ⇒ Fig. 99 allows the system to detect driv- ing situations in front of the vehicle.
Vehicles ahead can be detected up to a distance of about 10 m.
WARNING
The laser beam on the laser sensor can produce serious injuries to the
eyes.
● Never focus optical devices, e.g. a camera, a microscope or a magnify-
ing glass closer than 100 mm from the laser sensor.
● Note that the laser beam can stay active when the City Safety Assist
system is switched off or unavailable. The laser beam is not visible to the
human eye.
CAUTION
If the windscreen is dirty or frozen in the area of the laser sensor, e.g. due to
rain, mist or snow, the City Safety Assist system may subsequently fail to
operate.
● Always keep the laser sensor area free of dirt and freezing.
● Use a small brush to remove snow and a de-icer spray to remove ice.
CAUTION
A damaged windscreen in the laser sensor area may cause the City Safety
Assist function to fail to operate.
● Replace the windscreen if it is scratched, cracked or chipped by stones
in the laser sensor area. Only use a windscreen authorised by SEAT. Carrying
out repairs is not permitted (e.g. in the case of damage suffered in an im-
pact from a stone).
● When replacing the windscreen wipers, only use windscreen wipers au-
thorised by SEAT.
● Do not paint the laser sensor area on the windscreen, or cover it with ad-
hesives, or sedimentation, etc. 
