Checking and refilling levels
228
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear stick to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 277. The battery could
explode.•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•Al wa ys m ake s u re yo u ha ve n o t l e f t a ny o bj e c t s , s u ch as cl e an i n g cl o t h s
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

Checking and refilling levels
240Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– 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 engine
compartment diagram ⇒page 287. 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 instru-
ment 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 observe
the warnings ⇒page 227.Changing the brake fluid
The Maintenance Program indicates the brake fluid change
intervals.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 227 in
“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.
It is important that you use only brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. The slightly raised
pressures of warm tyres must not be reduced ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking tyre pressure
value is very important. If the tyre pressure is too high or too low, there is
an increased danger of accidents - particularly at high speeds.•A tyre can easily burst if the pressure is too low, causing an accident!•At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.•If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre pressure monitoring
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system uses the speed sensors of the ABS wheels. It operates by
analysing the speed and frequency spectrum of each wheel.
For optimum performance, use genuine SEAT tyres. In addition, check and
adjust tyre pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the central console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument cluster display. The system uses
ESP ⇒page 195.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases about 0.1 bar for each 10C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise
accordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!

Bulb changeGeneral notesBefore changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the sam e type. The type is inscribed
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle.

24)On this type of headlight, the bulb changes must be made by the SEAT dealer, given
that complex elements must be removed from the vehicle and a reset must be made
on the automatic control system incorporated.25)The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5
times more than that of halogen bulbs, this means that, except due to unusual circum-
stances, there is no need to change the bulbs for the whole life of the vehicle.
