In the engine compartment
● Open the bonnet  ⇒  page 180.
● The engine oil filler mouth can be recognised by the symbol  on the
cap ⇒ Fig. 112 and the dipstick by its coloured handle.
Check the engine oil level
● Pull out the dipstick and wipe it on a clean cloth.
● Replace the dipstick, pushing it in as far as it will go. If the dipstick to
measure engine oil has a mark, when you reintroduce it this mark should
slot into the corresponding groove located on the upper end of the tube.
● Remove the dipstick again and check the engine oil level ⇒ table on
page 187.
● After reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Fig. 111Operations required depending on the engine oil topping
up level:
Area ADo not top up oil
⇒ .Area BYou can add oil, but keep the level in this zone.
Area COil
must be added. After topping up the oil level should be
in area B.
Adding oil after checking the level
Only add engine oil in small quantities and in steps.
●
Unscrew the cap from engine oil filler mouth on the cylinder head
⇒ Fig. 112. If you are not sure where the cap is, request help from a special-
ist.
● Only refill using approved SEAT engine oil in small quantities (no more
than 0.5 ltr) ⇒ page 185.
● To avoid adding too much oil, each time you add a quantity, wait until
the oil has flowed into the crankcase so that it can be measured with the
dipstick.
● Check the oil level before adding any more oil. Do not top up with too
much engine oil ⇒ 
. ●
When the oil level is in at least the ⇒ Fig. 111 B
zone, insert the dip-
stick into the tube fully to avoid engine oil escaping when the engine is run-
ning.
● After topping up the oil, ensure that the cap is screwed on to the filler
mouth correctly.
WARNING
Oil could catch fire if it comes into contact with hot engine components.
This could lead to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the engine oil filler cap is cor-
rectly tightened. This will avoid engine oil spilling onto hot engine parts
when the engine is running.
CAUTION
● If the engine oil level is above the area A do not start the engine. You
should obtain professional assistance. Otherwise catalytic converter and
engine damage may occur.
● When refilling or changing service liquids, ensure that you put the liq-
uids into the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine!
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust system. 
Engine oil consumption
The consumption of engine oil can be different from one engine to another
and can vary during the useful life of the engine. 

nanceIf and whenTechnical Data

188In the engine compartment
Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 1 ltr./2000 km. In the case of new vehi-
cles, the consumption can exceed this figure over 5000 kilometres. For this
reason the engine oil level must be checked at regular intervals, preferably
when filling the tank and before a journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, or when climbing mountain passes, the oil
level should preferably be kept within area ⇒ Fig. 111 A
. 
Changing the engine oil
The engine oil must be changed regularly according to the specifications of
the Maintenance Programme.
Due to the problems linked with disposing of used oil and the need for suit-
able tools and special knowledge, always visit a Specialised workshop to
have the engine oil and filter changed. SEAT recommends visiting a Techni-
cal Service.
Detailed information on the service intervals are shown in the Maintenance
Programme.
Engine oil additives make new oil darker after the engine has been running
for a short period. This is normal and does not mean more frequent oil
changes are required.
WARNING
If, in exceptional circumstances, you must change the engine oil yourself,
please note the following:
● Wear eye protection.
WARNING (Continued)
● Always wait until the engine has completely cooled to avoid being
burned.
● Always keep your arms horizontal when unscrewing the oil drainage
bolt so that the oil does not run down your arms when it begins to drain.
● Use a suitable and large enough container to collect all of the used oil
in the engine.
● Never collect engine oil in empty food containers, cans, bottles and
other containers as not all people are able to identify engine oil.
● Oil is toxic and must be kept out of the reach of children.
For the sake of the environment
Before changing the engine oil, find a suitable location or service for proper
disposal.
For the sake of the environment
Always dispose of engine oil with the utmost respect for the environment.
Never dispose of used engine oil in places such as a garden, woods, drains,
roads, paths, rivers and drainage systems. 

WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Always observe any lit warning lamps.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle.
Note
On the display of the Portable Navigation System (supplied by SEAT)
⇒ page 222 an engine coolant temperature gauge can be seen. 
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25 °C (-13 °F) and protects the light alloy parts of the cooling system
against corrosion. It also prevents scaling and considerably raises the boil-
ing point of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of
distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
.
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. 

Vehicle care and maintenance
Vehicle care and maintenance
Care and cleaning the vehicle exterior Introduction
Regular maintenance and washing help to maintain the value of the vehicle.
This may also be one of the requirements for acknowledging warranty
claims in the event of bodywork corrosion or paint defects.
Products suitable for the care of your vehicle are available at any Technical
Service.
Additional information and warnings:
● 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
Vehicle care products may be toxic and hazardous. If vehicle care prod-
ucts are not suitable or are used inappropriately, this could result in acci-
dent, serious injury, burns or intoxication.
● Vehicle 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 vehicle 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 vehicle 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.
WARNING
Inappropriate care and cleaning of vehicle components may effect the ve-
hicle safety equipment, increasing the risk of severe injury.
● Vehicle components should only be cleaned and maintained in ac-
cordance with the manufacturer's instructions.
● Only use approved or recommended care products.
CAUTION
Cleaning products which contain solvents will damage the material.
For the sake of the environment
Only wash the vehicle in areas allocated for this purpose, to prevent dirty
water which may be contaminated by oil, grease or fuel, from entering the
drains. In some districts, washing vehicles outside wash bays is prohibited.
For the sake of the environment
Where possible, always use products which respect the environment. 

198Vehicle care and maintenance
For the sake of the environment
The remains of vehicle care products should not be disposed of with ordina-
ry household waste. Observe information provided by the manufacturer. 
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. The vehicle undercarriage should also be thoroughly wash-
ed at regular intervals.
Automatic car washes
Always observe the instructions provided at the automatic car wash. The
standard precautionary measures prior to entering the car wash should be
taken to avoid damage to the vehicle (close all windows, fold in exterior mir-
rors). If the vehicle is fitted with additional components (spoiler, roof-rack,
aerial...), check with the car wash supervisor whether these can enter the
car wash ⇒ 
.
The vehicle paintwork is so durable that the vehicle can normally be washed
without problems in an automatic car washing tunnel. However, wear and
damage to the paintwork will depend on the type of car wash used. SEAT
recommends the use of car washes without brushes.
To remove traces of wax on windows and to prevent wiper blades from
scratching, please observe the following ⇒ page 200, Cleaning windows
and exterior mirrors.
Washing the vehicle by hand
When washing the vehicle 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. Start at the roof and work downwards. Special vehicle 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
Sharp components on the vehicle may cause injury.
● Protect arms and hands from sharp edges when cleaning the vehicle
undercarriage or the interior of the wheel hubs.
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 exceed +60 °C (+140 °F).
● To avoid damage to the paintwork, do not wash the vehicle in full sun.
● Do not use rough sponges or similar which could damage the surface to
clean away the traces of insects.
● Never wipe the headlights with a dry cloth or sponge, always moisten
first. It is best to use soapy water.
● 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! 

200Vehicle care and maintenance
Cleaning windows and exterior mirrors
Cleaning windows and exterior mirrors
Spray windows and exterior windows with a standard window cleaner con-
taining alcohol.
Dry the windows with a clean chamois leather or a lint-free cloth. The cha-
mois leathers used on painted surfaces are not suitable for cleaning win-
dows because they are soiled with wax deposits which could smear the win-
dows.
Use window cleaner or a silicone remover to clean rubber, oil, grease and
silicone deposits off ⇒ 
.
Removing wax deposits
Automatic car washes and certain vehicle care products may leave wax de-
posits on the windows. These deposits can only be removed with a special
product or cleaning cloths. If wax deposits are left on the windscreen and
the rear window, the blades can scratch the glass. SEAT recommends you
wipe the wax deposits off the windscreen and the rear window with a soft
cloth each time after you have washed the vehicle.
A window cleaning detergent which helps to dissolve the wax may be added
to the windscreen washer fluid to prevent the wiper blades from scratching
the windscreen. Please ensure the you add the cleaning product in the cor-
rect proportions. Products for removing grease do not eliminate the wax de-
posits ⇒ 
.
Special cleaning products or window cloths are available at any Technical
Service. To remove wax deposits, SEAT recommends the following products: ●
For the hottest time of the year: the window cleaner for summer
use G 052 184 A1. Proportion 1:100 (1 part detergent, 100 parts water) in
the windscreen washer bottle.
● All year round: the window cleaner G 052 164 A2; proportion 1:2 in
windscreen washer bottle (1 part concentrate, 2 parts water) in winter, up to
-18 °C (-0.4 °F), or 1:4, during the rest of the year.
● Window cloths G 052 522 A1 for all windows and exterior mirrors.
Removing snow
Use a small brush to remove snow from the windows and exterior mirrors.
Removing ice
If possible, use a de-icing spray to remove ice. If you use an ice scraper,
push it in one direction only without swinging it. If you pull the scraper
backwards, the dirt may scratch the window.
WARNING
Dirty or misted windows reduce visibility in all directions and increase
the risk of accident and serious injury.
● Do not drive unless you have good visibility through all windows!
● Remove ice and snow from the windows and demist inside and out.
CAUTION
● Never mix our cleaning products with other products not recommended
by SEAT in the windscreen washer bottle. This could lead to flocculation and
may block the windscreen washer jets.
● Do not use hot or warm water to remove ice or snow from the windows
and exterior mirrors. The glass could crack!
● The heating element for the rear window is located on the inner side of
the window. Do not stick adhesive labels over the heating elements and
never clean the inside of the rear window with corrosive or acid products or
other similar chemical cleaning products. 

204Vehicle care and maintenance
WARNING
Additional underseal or anti-corrosion products could catch fire due to
the high temperatures reached by the exhaust gas system and other en-
gine components.
● Do not apply additional underseal or anti-corrosion products to the
exhaust pipes, catalytic converters, heat shields or other parts of the ve-
hicle which reach high temperatures.

Cleaning the engine compartment
The engine compartment of any motor vehicle is a potentially hazardous
area ⇒ page 180. The engine compartment should only be cleaned by qualified personnel. If
it is not correctly cleaned, the anti-corrosion coating and consequently elec-
trical components may be damaged. Moreover, water may filter directly into
the vehicle interior through the water chamber ⇒ 
.
If the engine compartment is very dirty, always take the vehicle to a Special-
ised workshop for professional cleaning. SEAT recommends visiting a Tech-
nical Service.
Water box
The water box is in the engine compartment, between the windscreen and
the engine, and beneath a perforated cover. Air is taken in through the wa-
ter box from outside to the vehicle interior via the heating and air condition-
ing system.
Leaves and other loose objects should be regularly cleaned away from the
water box either by hand or with a vacuum.
WARNING
When working on the engine or in the engine compartment, there is a
risk of injury, burns, accident or fire.
● Before starting work, please ensure you are familiar with the required
procedure and the safety precautions ⇒ page 180.
● SEAT recommends you have this work performed by a specialised
workshop.
CAUTION
If water is manually poured into the water box (for example, using a high
pressure cleaning appliance), this could cause significant damage to the ve-
hicle.
For the sake of the environment
Only wash the engine compartment in areas allocated for this purpose, to
prevent dirty water which may be contaminated by oil, grease or fuel, from
entering the drains. In some districts, the engine compartment may not be
washed outside the wash bays provided for this purpose. 

Vehicle care and maintenance
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.
