7. Always take the vehicle key with you when you leave the vehi- cle.
Switch on the hazard warning lights to warn other road users, for example:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. The two turn signal turn signal lamps   and the turn signal
lamp in the switch  will flash at the same time. The hazard warning lights
also work when the ignition is switched off.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h (50 mph), the brake light flashes several times per second to warn
vehicles driving behind. If you continue braking, the hazard warning lights
will come on automatically when the vehicle comes to a standstill. They
switch off automatically when the vehicle starts to move again.
WARNING
● The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
● Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
● The battery will run down if the hazard warning lights are left on for a
long time, even if the ignition is switched off.
● The use of the hazard warning lights described here is subject to the rel-
evant statutory requirements. 
Main beam assist*
Main beam assist (Light Assist)
The main beam assist operates, within the limits of the system and depend-
ing on the environmental and traffic conditions, as of a speed of 60 km/h
(40 mph) when it switches on automatically, and is then deactivated again
below 30 km/h (20 mph) ⇒ 
. This is managed via a camera situated on
the base of the interior rear vision mirror.
The main beam assist generally detects illuminated areas and deactivates
the main beam when passing through a town, for example. 

Introduction
Additional information and warnings:
● Changing wheels round
● Heating, ventilation, cooling
● Caring for and cleaning the vehicle exterior
WARNING
If the water from the windscreen washer does not contain enough anti-
freeze, it may freeze on the windscreen, reducing forward visibility.
● In winter, ensure the windscreen washer contains enough anti-freeze.
● In cold conditions, you should not use the wash/wipe system unless
you have warmed the windscreen with the ventilation system. The anti-
freeze could freeze on the windscreen and reduce visibility.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of acci-
dent and serious injury.
● Always replace damaged or worn blades or blades which do not clean
the windscreen correctly.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers. In cold weather, it may help to leave the vehi-
cle parked with the wipers in service position ⇒ page 119. 

122Lights and visibility
Recommended windscreen wipers
● For the hottest seasons we recommend summer G 052 184 A1 for clear
glass. Proportions of the mixture in the washer fluid tank: 1:100 (1 part con-
centrate per 100 parts water).
● All year round, G 052 164 A2 for clear glass. Approximate proportion of
the winter mixture, up to -18 °C (0 °F): 1:2 (1 part concentrate per 2 parts
water); otherwise, a 1:4 proportion of mixture in the washer fluid tank.
Reservoir capacity
The reservoir holds approximately 3 - 4 litres; in vehicles with headlight
washer, it is approximately 3 -6 litres.
WARNING
Never mix an unsuitable antifreeze or other similar additives with the
windscreen washer water. A greasy layer may be formed on the wind-
screen which will impair visibility.
● Use clean water with a window cleaner recommended by SEAT.
● If necessary, add a suitable antifreeze to the water in the reservoir.
CAUTION
● Do not mix cleaning products recommended by SEAT with other prod-
ucts. This could lead to flocculation and may block the windscreen washer
jets.
● When topping up service fluids, make absolutely certain that you fill the
fluids into the correct reservoirs. Using the wrong fluids could cause serious
malfunctions and engine damage! Rear vision mirror

● If necessary the right exterior mirror adjustment may need correcting.
Turn the knob to position R.
● In the Easy Connect system the exterior mirrors can be adjusted using
the CAR
button and the function button SETUP.
Tilt function for front passenger exterior mirror*
The mirror can automatically tilt slightly to provide a better view of the kerb
when parking backwards. The control must be in the position R for this fea-
ture to be operational.
The mirror returns to its original position as soon as you drive forwards at
over 15 km/h (10 mph) or switch off the ignition. It also returns to its origi-
nal position if the position of the control is adjusted.
WARNING
Convex or wide-angle* exterior mirrors give a larger field of vision. How-
ever, they make objects look smaller and further away than they really
are. If you use these mirrors to estimate the distance to vehicles behind
you when changing lane, you could misjudge the distance. Risk of acci-
dent!
CAUTION
● If one of the mirror housings is knocked out of position (e.g. when park-
ing), the mirrors must first be fully retracted with the electric control. Do not
readjust the mirror housing by hand, as this will interfere with the mirror ad-
juster function.
● Before washing the vehicle in an automatic car wash, please make sure
to retract the exterior mirrors to prevent them from being damaged. Electri-
cally retractable exterior mirrors must NOT be folded in or out by hand. Al-
ways use the electrical power control.
Note
If the electrical adjustment should fail to operate, both of the mirrors can be
adjusted by hand by lightly pressing the edge of the mirror glass. Anti-dazzle rear vision mirrors
Your vehicle is fitted with an interior rear vision mirror with a
manual or automatic control for anti-dazzle position.

WARNING
In the event that an automatic anti-dazzle rear vision mirror breaks, an
electrolyte fluid may leak. This could cause irritation to the skin, eyes
and respiratory organs. If you come into contact with this liquid, it must
be rinsed with large quantities of water. If necessary, get medial help.
CAUTION
In the event that an automatic anti-dazzle rear vision mirror breaks, an elec-
trolyte fluid may leak. This liquid attacks plastic surfaces. Clean the liquid
with a wet sponge as soon as possible.
Note
● If the light incident in the interior rear vision mirror is obstructed (e.g.
with the sun blind*), the anti-dazzle rear vision mirror with automatic set-
ting will not operate perfectly.
● When the interior lights are on or reverse gear engaged, the rear vision
mirrors do not darken with automatic adjustment for anti-dazzle position. 

178Driver assistance systems
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.

194Trailer
Trailer
Trailer towing What do you need to bear in mind when towing a trailer?
Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If you wish to retrofit a towing bracket, consult ⇒ page 196.
Connectors
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available in any Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If you do not load the trailer up
to the maximum permitted trailer weight, you can then climb correspond-
ingly steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and
therefore the vehicle climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every further 1000 m (or part thereof). The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
When possible, operate the trailer with the maximum permitted drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit. The figures for
trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for
the towing bracket, are given in the vehicle documentation or in ⇒ chap-
ter Technical Data.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres
in accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard rear vision mirrors. If this is not the case, you should have addi-
tional exterior mirrors fitted. Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors to give sufficient vision to the
rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents. 

Care and cleaning
Washing the car by hand
When washing the car by hand, use plenty of water to soften the dirt first,
and rinse off as well as possible.
Then clean the vehicle with a soft sponge, glove or brush using only slight
pressure. You should start on the roof and work down. Special car shampoo
should only be used for very persistent dirt.
Rinse the sponge or glove thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second sponge for
this.
WARNING
● The vehicle should only be washed with the ignition switched off.
Failure to do so could result in an accident.
● Do not clean the underside of chassis, the inside of wheel arches or
wheel trims without protecting your hands and arms. You may cut your-
self on sharp-edged metal parts. Otherwise, there is a risk of sustaining
cuts.
● When washing the car during the winter season: water and ice in the
brake system can reduce braking effectiveness: risk of accident!
CAUTION
● Do not wash the vehicle in direct sunlight – otherwise the paint can be
damaged.
● Do not use sponges, abrasive household sponges or similar to clean in-
sect remains. This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from the headlights at regular in-
tervals, for instance when filling the fuel tank. The headlights should only
be washed with water, do not wipe them with a dry cloth or sponge. It is
best to use soapy water. ●
Never wash tyres with a jet that sprays the water out in a direct stream.
This could damage the tyres even if the spray is kept at a distance and only
used for a very short time.
● Before washing the vehicle in an automatic car wash, please make sure
to retract the exterior mirrors to prevent them from being damaged. Electri-
cally retractable exterior mirrors must not be folded in or out by hand. Al-
ways use the electrical power control.
For the sake of the environment
The car should only be washed in special wash bays. This prevents oily wa-
ter from getting into the public drains. In some places, washing vehicles
anywhere else may be prohibited. 
Sensors and camera lenses
● Use a small brush to remove snow and a de-icer spray to remove ice.
● Clean the sensors with a solvent-free product and a soft, dry cloth.
● Moisten the camera lens using a standard alcohol-based glass cleaning
agent and clean the lens with a dry cloth. The area in front of the active
Lane Assist* lens area is normally cleaned with the windscreen washer.
CAUTION
● When you clean the vehicle with a pressure washer,
– stay a suitable distance from the sensors on the front and rear bump-
ers.
– Do not clean the camera lenses or surrounding area with the pressure
washer.
● Never use warm or hot water to remove snow and ice from the reverse
camera lens, as it could crack the lens.
● Never use abrasive cleaning agents on the lens. 
