Parking distance warning system*
Introduction
The parking distance warning system assists the driver when parking. If the
rear of the vehicle is approaching an obstacle, an intermittent audible warn-
ing is emitted. The shorter the distance, the shorter the intervals between
tones. If the vehicle is too close to the obstacle, the audible warning be-
comes 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.

● 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 boots, etc. This could re-
sult in damage to your vehicle.
● Although the parking distance warning system detects 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 indicate it. Therefore, it will not warn you of these objects. Ignoring
the warnings of the parking distance warning system could cause consider-
able 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, i.e. 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. 

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 i.e. 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. 

Laser sensor
Fig. 96 On the wind-
screen: City Safety Assist
function laser sensor
Fig. 97 Laser sensor de-
tection area
A laser sensor on the windscreen ⇒ Fig. 96 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, i.e. 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, i.e. 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 (i.e. in the case of damage suffered in an impact
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. 

Special driving situations
Fig. 99 A: Vehicle on a bend. B: Motorcyclist driving
ahead out of range of the laser sensor
Fig. 100 Other vehicles
changing lanes
The City Safety Assist function has physical limits, and has limits deter-
mined by the system itself. In certain circumstances, this may produce reac-
tions from the City Safety Assist system, that are late or unexpected by the
driver. For this reason, always pay due attention and if necessary, intervene. 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 opposite lane
⇒ Fig. 99 A.
To interrupt the deceleration you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehicles in front if they are in the
sensor detection zone ⇒ Fig. 99 B. This applies especially to narrow vehi-
cles such as motorbikes.
Other vehicles changing lanes
Vehicles changing lane in close proximity can cause an unexpected brake
from the City Safety Assist system ⇒ Fig. 100. To interrupt the deceleration
you can accelerate, turn the steering wheel or press the clutch. 

flashesPossible causeSolution
The Start-Stop system is not
available.Contact a Specialised
workshop.
Some warning and control lamps will light up briefly when the ignition is
switched on to check certain functions. They will switch off after a few sec-
onds.
WARNING
If the warning lamps are ignored when they light up, the vehicle may
stall in traffic and cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle at the next opportunity.
CAUTION
Failure to heed the control lamps when they light up may result in damage
to the vehicle. Start-Stop system
Fig. 101 At the top of
the centre console: Start-
Stop system button
With the Start-Stop system enabled, the engine is automatically stopped
when the vehicle is at a standstill. It will start again automatically as re-
quired.
This function remains enabled while the ignition is switched on. The instru-
ment panel display shows information on the current status ⇒ page 160.
Disconnect the Start-Stop system by hand whenever crossing water.
Vehicles with a manual gearbox
● When the vehicle is stopped, put it into neutral and release the clutch
pedal. The engine will stop.
● To restart, simply engage the clutch. 

Driver assistance systems
These are the basic operation conditions: doors closed, brake pedal press-
ed down and vehicle in neutral. The system gets activated on engaging
gear.
After removing your foot from the brake pedal, the braking force is main-
tained for a few seconds to prevent the vehicle from moving backward when
putting into gear. This short space of time is enough to start the vehicle
with ease.
This system also works when reversing uphill.
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the hand brake immediately.
● If the engine stalls, depress the brake pedal or use the hand brake
immediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system. 
