Care and cleaning
sponge. If the stains are difficult to remove, a washing paste can be applied
directly onto the stain and worked into the fabric. The surface will then have
to be wiped with clear water to remove any residue left by the paste. To do
so, use a damp cloth or sponge and then dab the stain with an absorbent
cloth.
Remove chocolate or make-up stains with a cleaning paste (for e.g., soft
soap). Then remove the soap with water (wet sponge).
A spirit-based cleaner can be used to remove grease, oil, lipstick or ball
point pen. Then dab the dissolved grease or colour particles off with an ab-
sorbent cloth or similar. You may also have to treat the stain once more us-
ing washing paste and water.
If the covers or textile trim panels are badly soiled we recommend that you
have them cleaned by a professional cleaning company with a shampoo
and spray.
Note
Open Velcro fasteners on clothes can damage the seat upholstery. Make
sure that Velcro fasteners are closed. 
Natural leather
SEAT does everything possible to preserve the genuine qual-
ities of this natural product. General information
Our range of leathers is large. The main type used is nappa in various forms,
that is, leather with a smooth surface in various different colours.
The amount of dye used determines the appearance and properties of leath-
er. If the leather is left in a more natural state, it retains its typical natural
napped appearance and confers excellent all-weather properties to the
seats. Fine veins, healed scars, insect bites, wrinkles and a subtle variation in shading remain visible; these are the characteristic features of genuine
natural leather.
Natural napped leather does not have a protective surface coating of dye. It
is therefore somewhat more prone to damage. This should be borne in mind
if children or pets often travel in the car, or if there are other factors that
could lead to damage.
Types of leather with a coloured surface coating are likely to be more resist-
ant to damage. This has a great advantage for day-to-day use. However, this
means that the typical natural characteristics of the surface are less appa-
rent, though this does not affect quality.
Cleaning and care
Due to the natural properties of the specially selected hides employed, the
finished leather has a certain sensitivity to grease and dirt, etc. so a degree
of care is required in everyday use and when looking after the leather. Dark
clothing (especially if damp or incorrectly dyed) may stain leather uphols-
tery. Dust and grit in the pores and seams can scratch and damage the sur-
face. Therefore leather should be cleaned at regular intervals, depending on
the actual amount of use. When they have been in use for a certain time,
your car seats will acquire a typical and unmistakable patina. This is charac-
teristic for leather as a natural product and is a sign of genuine quality.
To maintain the value of natural leather you should note the following
points:CAUTION
● Avoid exposing leather to direct sunlight for long periods, otherwise it
may tend to lose some of its colour. If the car is left for a prolonged period
in the bright sun, it is best to cover the leather.
● Sharp-edged objects on clothing, such as belts, zip fasteners, rivets or
similar, can also leave permanent scratches and rough marks on the surface
of the leather. 

Care and cleaning
CAUTION
On no account use solvents (such as petrol, turpentine), wax polish, shoe
cream or similar materials. 
Cleaning Alcantara upholstery
Removing dust and dirt
– Moisten a cloth just a little and wipe down the seat covers.
Removing stains
– Moisten a cloth with lukewarm water or diluted white spirits.
– Dab at the stain. Start at the outside and work inwards.
– Dry the area you have cleaned with a soft cloth.
Do not use leather cleaning products on Alcantara seat covers.
You may use a suitable shampoo on dust and dirt.
Dust and grit in the pores and seams can scratch and damage the surface. If
the car is left standing in the sun for long periods, Alcantara leather should
be protected against direct sunlight to prevent it from fading. However,
slight colour variations will arise in normal use.
CAUTION
● Do not use solvents, wax polish, shoe cream, stain removers, leather
cleaning products or any similar products on Alcantara.
● To avoid damage, stubborn stains should be removed by a specialised
workshop.
● On no account use brushes, hard sponges or similar utensils. Seat belts
–
Keep the seat belts clean.
– For cleaning, use a mild solution of soap and water.
– Check the condition of the seat belts at regular intervals.
The retract function may not operate properly in very dirty belts. Make sure
that the inertia reel seat belts are completely dry before allowing them to
retract.
CAUTION
● Do not remove the seat belts from the vehicle to clean them.
● Do not use chemical cleaning agents on the seat belts, as this can dam-
age the webbing. Ensure that the seat belts do not come into contact with
corrosive fluids.
● If you find any damage to the belt webbing, belt fittings, the belt retrac-
tor or the buckle, the belt in question must be replaced by a specialised
workshop. 

248Checking and refilling levels
The engine management automatically adapts to the natural gas used ac-
cording to its quality. Therefore, different quality gases can be mixed in the
tank, without the need for comprehensive draining before applying a differ-
ent quality gas.
The instrument panel display shows information on the current natural gas
quality ⇒ page 73.
Natural gas and safety
If you can smell gas or suspect that there is a leak ⇒ 
:
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● Seek specialist assistance. Have the fault repaired.
WARNING
Failure to act when you can smell gas in the vehicle or when refuelling
can cause serious injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.
Note
Have natural gas system checked regularly by a specialised workshop in ac-
cordance with the Maintenance Programme. 

WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect to the lowest expected ambient temperature in the zone in which
the vehicle is to be used.
● When the outside temperature is very low, the coolant could freeze
and the vehicle would be immobilised. In this case, the heating would
not work either and inadequately dressed passengers could die of cold.
CAUTION
The original additives should never be mixed with coolants which are not
approved by SEAT. Otherwise, you run the risk of causing severe damage to
the engine and the engine cooling system.
● If the fluid in the expansion tank is not purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate coolant. The coolant must be changed as soon as possible if this is
the case! This could result in serious faults and engine damage.
For the sake of the environment
Coolants and additives can contaminate the environment. If any fluids are
spilled, they should be collected and correctly disposed of, with respect to
the environment. Topping up coolant
Top up coolant when the level is below the MIN (minimum)
mark.
Fig. 156 Engine com-
partment: Coolant expan-
sion tank cap
Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off
– Read off the coolant level on coolant expansion tank. When the
engine is cold, the coolant level should be between the marks.
When the engine is hot, it may be slightly above the upper
mark.
Topping up coolant
– Wait for the engine to cool down.
– Cover the coolant expansion tank cap with a cloth and carefully
unscrew it to the left ⇒

WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table
