218Vehicle maintenance and cleaning
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.

Cleaning the engine compartment
Take special care when cleaning the engine compartment.
Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehi-
cle is frequently driven on salted roads. To prevent the salt corroding the ve-
hicle, the entire engine compartment should be thoroughly cleaned before
and after winter.
Your Technical Services have got the necessary workshop equipment to pro-
vide the correct cleaning and preserving products. For this reason, we rec-
ommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine
cleaned. On commissioning this work, ensure that all surfaces, seams,
joints and components in the engine compartment are given anti-corrosion
treatment.
WARNING
● When working in the engine compartment, always observe the safety
warnings ⇒ page 233.
● Before opening the bonnet, switch the engine off, apply the hand-
brake firmly and always remove the key from the ignition.
● Allow the engine to cool before you clean the engine compartment.
● Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.
● Moisture, ice and salt on the brake system may affect braking effec-
tiveness. Risk of accident. Directly after washing, avoid sudden and
sharp braking.
● Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!
For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason, en-
gine washing should be carried out only by a specialised workshop or a pet-
rol station. 
Vehicle interior maintenance Introduction
The dye used in many modern garments, for example dark jeans, is not al-
ways sufficiently colour-fast. Seat upholstery (material and leather), espe-
cially when light-coloured, may visibly discolour if the dye comes out of
clothing (even when used correctly). This is not an upholstery defect but in-
dicates that the dye in the item of clothing is not sufficiently colour-fast. 

246Checking and refilling levels
Brake fluid
Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 173 In the engine
compartment: Brake fluid
reservoir cover
– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is shown in the corresponding en-
gine compartment illustration ⇒ page 292. The brake fluid reservoir has a
black and yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear.
However, if the level goes down noticeably in a short time, or drops below
the “MIN” mark, there may be a leak in the brake system. A display on the
instrument panel will warn you if the brake fluid level is too low ⇒ page 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 233.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. We recommend that you have the brake fluid changed by a Technical Serv-
ice.
Before opening the bonnet, please read and follow the warnings ⇒ 
in
Safety instructions on working in the engine compartment on page 233 in
section “Safety notes for working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of
the brake fluid. Heavy use of the brakes may then cause a vapour lock
which could impair the braking effect.
Be sure to always use the correct brake fluid. Only use brake fluid that ex-
pressly meets VW 501 14 standards.
You can buy VW 501 14 standard brake fluid in a SEAT dealership or SEAT
Official Service. If none is available, use only high quality brake fluid that
meets DIN ISO 4925 CLASS 4 standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one that is not of a high quality may
affect operation of the brake system and reduce its effectiveness. Never use
a brake fluid if the container does not state that it complies with VW 501 14,
DIN ISO 4925 CLASS 4 standards, or USA standards FMVSS 116 DOT 4. 

If and when
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch off the engine. Switch on the hazard warning lights.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below
– Remove the hub cap. Also see ⇒ page 262.
– Slacken the wheel bolts.
– Raise the vehicle with the jack at the corresponding point.
– Remove the wheel and then mount the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the hub cap. 
After changing a wheel
After changing the wheel there are still tasks to complete. – Put the tools and jack back in the luggage compartment. 

If and when
You will also find instructions for operating the compressor.
WARNING
● Do not attempt to repair a puncture with the sealing product if the
tyre has been damaged by driving the vehicle after the tyre has lost its
air.
● Always observe warnings and follow instructions concerning com-
pressor and sealing compound carefully.
● Do not drive faster than 80 km/h (50 mph), avoid heavy acceleration,
hard braking and fast cornering.
● Tyres which have been repaired with sealing compound are only suit-
able for temporary use over a short period. Therefore, please drive care-
fully to the next available specialised workshop.
For the sake of the environment
If you have to dispose of a sealant can, go to a specialised waste service or
to a SEAT Technical Service, where the product can be recycled in an appro-
priate waste container.
Note
● If sealing product should leak out, leave it to dry. This way you can pull it
off like a piece of foil.
● Observe the expiry date stated on the sealing compound can. Have the
sealing compound exchanged by a specialised workshop.
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product. Preparation work
Certain steps must be taken before repairing a tyre.
–
If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible.
– Apply the handbrake firmly.
– Engage first gear , or put the selector lever to position P.
– All occupants should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Check whether a repair is possible using the Tyre Mobility Sys-
tem “General information and safety notes.”
– Unscrew inflation cap from the affected wheel.
– Take the tyre repair kit out of the luggage compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
Take special care if you have to repair a tyre on a slope.
Note
Please observe legal requirements when doing so. 
