Parking aid
General information
Various systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The rear parking aid is an audible assistant that warns about obstacles lo-
cated behind the vehicle ⇒ page 179.
During parking, the plus parking aid assists you visually and audibly about
obstacles detected in front and behind the vehicle ⇒ page 179.
WARNING
● Always pay attention (also when looking straight ahead) to traffic and
the vehicle surroundings. The assistance systems are not a replacement
for driver awareness. When inserting or removing the vehicle from a park-
ing space, or when performing similar manoeuvres the driver always as-
sumes the responsibility.
● Take into account that the system is not always in conditions to rec-
ognise or represent certain surfaces, such as dress fabric: Risk of causing
an accident!
● The sensors and cameras have blind spots, making the detection of
people and objects impossible. Pay special attention to children and ani-
mals: Risk of causing an accident!
● Always keep visual control of the vehicle surroundings: use the rear
vision mirrors for additional help.
CAUTION
● Under certain circumstances, the system does not detect or display cer-
tain objects:
–Objects such as snow chains, trailer draw bars, bars or fences
– Objects that are located above the sensors, such as protrusions in a
wall.
– Objects with certain surfaces or structures, such as wire mesh fences
or powder snow.
● When the vehicle approaches a low obstacle, it could disappear from
the angle of measurement. In this case, take into account that the system
will no longer warn about this obstacle.
● The knocks or damage on the radiator grille, bumper, wheel arch and ve-
hicle underbody can adjust the orientation of the sensors. This can affect
the parking aid function. Have the function checked by a specialised work-
shop.
Note
● In certain situations, the system can give a warning even though there is
no obstacle in the detected area, e.g:
–for roads with certain surfaces, or with long grass
– for external ultrasound sources, such as cleaning vehicles
– In downpours, intense snow or dense exhaust gases
● In order to familiarise yourself with the system, it is advised that you
practice parking in an area or car park that is free from traffic. There must be
good weather and light conditions.
● The volume and tone of the warnings can be modified, in addition to the
indications ⇒ page 181.
● In vehicles without a driver information system, these parameters can be
modified in a SEAT Official Service or in a specialised workshop.
● Please observe information on towing a trailer ⇒  page 182.

● The display on the Easy Connect screen shows a slight time delay.
● To ensure that the parking aid works properly, the sensors must be kept
clean and free of ice and snow. 
Rear parking aid*
The rear parking aid is an audible assistant. Description
There are sensors integrated in the rear bumper. When the sensors detect
an obstacle, you are alerted by audible warnings.
Make sure that the sensors are not covered by adhesives, residues and the
like, given that this could affect the system operation. Cleaning instructions
⇒ page 199.
The approximate measurement range of the sensors is:
rearside0.90 mcentre1.60 m
As you approach the obstacle, the time interval between the audible warn-
ings will be reduced. When you reach around 0.30 m the warning will be
constant: Do not continue to move forward (or backward) ⇒ 
in General
information on page 178, ⇒  in General information on page 178 !
If you maintain separation from the obstacle, the volume of the warning be-
gins to reduce after four seconds (does not affect the tone of the constant
warning).
Activate
When engaging reverse gear, the parking aid is automatically switched on.
This is confirmed with a short warning. Plus parking aid*

Towing bracket
If the trailer power socket is occupied, the rear parking aid sensors will not
activate when reverse gear is engaged, or when the button  is pressed.
This function may not be covered under warranty if the towing bracket is not
factory-fitted. This causes the following limitations:

There will be no warning about the presence of obstacles in the rear area.
The monitoring in the front area remains active. The optical display changes

Care and cleaning
General information
Regular care helps to maintain the value of the vehicle.
Regular and careful care helps to maintain the value of the vehicle. This may
also be one of the requirements for upholding any warranty claims in the
event of corrosion or paint defects.
SEAT Official Services and specialist retailers carry stocks of suitable car
care materials. Please follow the instructions for use on the packaging.
WARNING
● Cleaning products and other materials used for car care can be dam-
aging to your health if misused.
● Always keep care products in a safe place, out of the reach of chil-
dren. Failure to comply could result in poisoning.
For the sake of the environment
● If possible, use environmentally friendly products.
● The remains of car care products should not be disposed of with ordina-
ry household waste. Care of vehicle exterior
Washing the vehicle
The longer substances such as insects, bird droppings, resinous tree sap,
road dirt, industrial deposits, tar, soot or road salt and other aggressive ma-
terials remain on the vehicle, the more damage they do to the paintwork.
High temperatures (for instance due to strong sunlight) further intensify the
corrosive effect.
After the period when salt is put on the roads it is important to have the un-
derside of the vehicle washed thoroughly.
Automatic car washes
Before going through a car wash, be sure to take the usual precautions such
as closing the windows and roof. If the vehicle has special accessories such
as spoilers or a roof carrier or two-way radio aerial, etc., it is advisable to
consult the car wash operator.
It is best to use a car wash without revolving bristles if possible.
Washing the vehicle with a high pressure cleaner
When washing the vehicle with a high-pressure cleaner, always follow the
operating instructions for the equipment. This applies particularly to the op-
erating pressure and the spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses or seals. The same applies to
the parking aid sensors*, which are located in the rear bumper.
Do not use a nozzle that sprays the water out in a direct stream or one that
has a rotating jet for forcing off dirt. 
