● Working in the engine compartment ⇒ page 180
● Care and cleaning of the vehicle interior ⇒ page 205
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Car-care products may be toxic and hazardous. If car care products are
not suitable or are used inappropriately, this could result in accident, se-
rious injury, burns or intoxication.
● Car care products must always be stored in the original container
which should be kept closed.
● Observe information provided by the manufacturer.
● To prevent confusion, never store car care products in empty food
cans, bottles or other containers.
● Keep all care products out of reach of children.
WARNING (Continued)
● Harmful vapours may be produced when using car care products.
Therefore, care products should only be used in well-ventilated spaces or
in the open air.
● Never use fuel, turpentine, engine oil, acetone or any other volatile
liquid to wash, clean or care for the vehicle. These are toxic and highly
flammable.

Vehicle care and maintenance
CAUTION
To prevent damage to the vehicle, please observe the following before en-
tering an automatic car wash :
● Compare the distance between the vehicle wheels and the distance be-
tween the guide-rails of the car wash to prevent damage to the wheels and
tyres!
● Switch off the rain sensor before taking the vehicle to an automatic car
wash.
● Compare the height and width of your vehicle with the available height
and width when entering and driving through the car wash.
● Fold in exterior mirrors Electrically retractable exterior mirrors must not
be folded in or out by hand. Always use the electrical power control.
● To avoid damaging the bonnet paintwork, rest the windscreen wipers on
the windscreen after drying the wiper blades. Do not let them fall!
● Lock the rear lid to prevent it from opening unexpectedly while inside
the car wash. 
Washing the vehicle with high pressure cleaning apparatus
When cleaning the vehicle with a high-pressure cleaner, always follow the
operating instructions for the equipment. Pay special attention to the re-
quired pressure of the jet and the distance between the jet and the vehicle
⇒ 
.
Keep a suitable distance from soft materials, such as rubber hoses or insu-
lating material, and from the parking distance warning system sensors. The
sensors of the parking distance warning system are situated on 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 ⇒ 
.
WARNING
The incorrect use of high pressure cleaning equipment could result in
permanent damage, visible or invisible, to the tyres or other materials.
This could result in a serious accident.
● Ensure there is a suitable distance between the nozzle and the tyres.
● Never wash tyres with a concentrated jet or so-called “dirt blasters”.
Even at large spraying distances and short cleaning times, you may dam-
age the tyres.
WARNING
After the vehicle has been washed, the braking effect will be reduced
(and the braking distance increased) due to moisture (and ice in winter)
on the brakes.
● Dry the brakes and remove ice by braking carefully. Ensure that you
are not endangering other road-users or breaking traffic regulations in
the process.
CAUTION
● The temperature of the water must not be above +60 °C (+140 °F).
● To avoid damage to the paintwork, do not wash the vehicle in full sun.
● To ensure that the system functions well, the sensors located on the
bumper must be kept clean and free from ice. When cleaning with pressure
hoses and steam cleaners, the sensors should be sprayed only briefly. A
distance of 10 cm between the sensors and the steam / hose nozzle must
be observed.
● Do not use a high pressure cleaner to remove ice or snow from windows
● Washing the vehicle in low temperatures: When washing the vehicle
with a hose, do not direct water into the lock cylinders or the gaps around
the doors, rear lid, or sunroof. Locks and seals could freeze! 

Cleaning and changing windscreen wiper blades
Fig. 119 Changing the
front wiper blades
Fig. 120 Changing the
rear wiper blade
The windscreen wiper blades are supplied as standard with a layer of graph-
ite. This layer is responsible for ensuring that the wipe is silent. If the graph-
ite layer is damaged, the noise of the water as it is wiped across the wind-
screen will be louder. Check the condition of the wiper blades regularly.
If the wipers scrape
across the glass they should be changed if they are damaged, or cleaned if
they are dirty ⇒ 
.
Damaged wiper blades should be replaced immediately. Wiper blades are
available from specialised workshops.
Lifting and unfolding the wiper arms
The wiper arm may only be lifted at the point where it is fastened to the
blade.
For windscreen wipers, please note: the wiper should be in service position
before unfolding it ⇒ page 89.
Cleaning windscreen wiper blades
● Lifting and unfolding the wiper arms.
● Use a soft cloth to remove dust and dirt from the windscreen wiper
blades.
● If the blades are very dirty, a sponge or damp cloth may be used ⇒ 
.
Changing the windscreen wiper blades
● Lifting and unfolding the wiper arms.
● Hold down the release button ⇒ Fig. 119 1
while gently pulling the
blade in the direction of the arrow.
● Fit a new wiper blade of the same length and design on to the wiper arm
and hook it into place.
● Rest the wiper arms back onto the windscreen.
Changing the rear wiper blade
● Lift the windscreen wiper arm and fold it at an angle of approximately
60° ⇒ Fig. 120.
● Press and hold the release button 1

Vehicle care and maintenance
● Do not polish dirty surfaces.
● Do not use products containing solvents.
● Do not use hard wax.
CAUTION
Chrome hub caps or wheel covers may have been painted additionally. Do
not treat them with aluminium or chrome wax products, nor chrome or alu-
minium polish. Instead, use commercial paint wax or polish. 
Cleaning wheels
Cleaning steel wheels
Use an industrial cleaner to remove brake dust. Therefore, clean wheels reg-
ularly with a separate sponge.
Any damage to the paint on steel wheels should be touched up before the
metal starts to rust.
Caring for and cleaning alloy wheels
Remove road salt and brake dust by washing the wheels approximately
once a fortnight. Use an acid free detergent to clean the wheel rims. SEAT
recommends treating the wheel rims thoroughly with a hard wax about
once every three months.
It is important to remove road salt and brake dust by washing the wheels at
regular intervals, otherwise the finish will be impaired.
Always use an acid-free detergent for alloy wheel rims. Car polish or other
abrasive agents should not be used for maintaining the rims.
If the protective coating on the paint has been damaged (for example, hit by
a stone), it should be repaired immediately. Caring for rubber seals
The rubber seals on doors, windows, etc., remain flexible, provide a better
seal and last longer if they are regularly treated with a product specifically
designed for use on rubber.
Before applying the product, use a soft cloth to remove dust and dirt from
the rubber seals.

De-icing the door lock cylinder
To de-ice the lock cylinders, SEAT recommend the use of genuine SEAT spray
with lubricating and anti-corrosive properties.
CAUTION
The use of products containing degreasing agents to de-ice the locks may
rust the lock cylinder. 
Protection of vehicle undercarriage
The vehicle underbody is coated to protect it from chemical and mechanical
damage. The protective coat on the undercarriage may wear through use
while driving. Therefore, SEAT recommends that the protective coating on
the undercarriage and on the running gear should be regularly checked, and
repaired if necessary. 

Caring for and cleaning the vehicle interior
Introduction
The dye from many items of modern clothing (e.g. dark jeans) is not always
solid enough. Seat upholstery (material and leather), especially when light-
coloured, may visibly discolour if the dye comes out of clothing (even when
used correctly). This is not an upholstery defect but indicates that the dye in
the item of clothing is not solid enough.
