Coolant temperature gaugeThe coolant temperature gauge ⇒ fig. 38 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Cold temperature
If the needle is still on the left of the dial, this indicates that the engine has
not yet reached operating temperature. Avoid high revs and heavy accelera-
tion and do not make the engine work hard. Normal temperature
In normal operations, the needle will settle somewhere in the centre of the
dial once the engine has reached running temperature. The temperature may
also rise when the engine is working hard, especially at high outside temper-
atures. This is no cause for concern, provided the warning lamp
 does not
light up in the instrument panel.
Warning temperature
If the symbol
 flashes in the display, this means that either the coolant
temperature is too high or the coolant level is too low ⇒page 78.
WARNING
•Before opening the bonnet and checking the coolant level, observe the
warning information ⇒page 221.•Never open the bonnet when steam or coolant is being released from it.
This could lead to burns. Wait until you can no longer see or hear escaping
steam or coolant.Caution
Accessories in front of the air inlet reduce the cooling effect of the coolant. At
high outside temperatures and high e ngine loads, there is a risk of the
engine overheating.

Cockpit
78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that the control function of the ABS is out of action. As
a result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.
Fault in the cooling system

Faults in the cooling system must be rectified immediately.If the
 symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 226.
– Add more coolant if necessary ⇒page 227.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
 has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low

If the engine oil pressure is too low the fault must be rectified
immediately.If the

symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 224.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 224.
Engine oil level correct
If the
 symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on. Do not continue to run the engine, even at
idle speed .

Technical Data
If you drive by mistake with the handbrake still applied, you will hear a
warning buzzer and the display will show the message:
Handbrake applied
The handbrake warning is enabled after driving for 3 seconds at a speed
above 5 km/h.
The handbrake warning lamp
 lights up when the handbrake is applied
with the ignition on.
WARNING
Please note that the handbrake should be released all the way. If it is only
partially released, this will cause rear brakes overheating, which can
impair the function of the brake system and could lead to an accident.
Caution
Once the vehicle has come to a standstill, always apply the handbrake firmly
and then, on a manual gearbox, engage a gear, or select P on an automatic.Parking
The following points will ensure there is no risk of the car
rolling away accidentally after it is parked.– Use the foot brake to stop the vehicle.
– Apply handbrake firmly.
– Switch the engine off.
– On a manual gearbox engage 1st gear or on an automatic move the selector lever to P ⇒ .
When parking on slopes:
Turn the steering wheel so that the, if the vehicle moves, it will do so towards
the curb.
WARNING
•Do not leave anyone (especially children) in the vehicle when it is
locked. Locked doors could delay assistance in an emergency, potentially
putting lives at risk.•Never leave children unsupervised in the vehicle. They could release
e.g. the handbrake or gear lever, moving the vehicle and causing an
accident.
Parking aid acoustic systemGeneral notesVarious systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The SEAT parking system gives an acoustic warning if there are any obstacles
behind your car ⇒ page 170.
When you are parking, SEAT parking system plus warns you acoustically and
optically about obstacles in front of and behind the vehicle ⇒page 170.
Note
To ensure the acoustic parking aid works properly, the sensors must be kept
clean and free of snow and ice.

Corrosion
There may be a tendency for dirt to build up on the brake pads and corrosion
to form on the discs if the car is used infrequently, or if you only drive low
mileages without using the brakes very much.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times from a
moderately high speed
⇒.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest qual-
ified workshop and have the fault rectified. On the way to the dealer, be
prepared to use more pressure on the brake pedal, and allow for longer stop-
ping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too low.
The brake fluid level is monitored electronically.
WARNING
When applying the brakes to clean off deposits on the pads and discs,
select a clear, dry road. Be sure not to inconvenience or endanger other
road users. Risk of accident.
Caution
•Never let the brakes “drag” by leaving your foot on the pedal when you do
not really intend to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.•Before driving down a long, steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the selector lever to a lower gear position
if your car has automatic transmission). This makes use of engine braking and prolongs the service life of the brakes. If you still have to use the brakes,
it is better to brake firmly at intervals than to apply the brakes continuously.
Note
If you wish to equip the car with accessories such as a front spoiler or wheel
covers, it is important that the flow of air to the front wheels is not obstructed,
otherwise the brakes can overheat.Brake servo
The brake servo assists the driver when brakingThe brake servo amplifies the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move while in neutral, when the motor is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed or
because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.

Technical Data
Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
– Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal friction in the engine is
greater than later on, when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gently, its life will be increased and its oil consumption,
reduced.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an
Authorised Service Centre more frequently than recommended in the Ser vice
Schedule.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be “dried” by pressing the pedal to restore full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.•If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.•On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed and
change down into a lower gear (or move the selector lever to a lower gear if

Driving and the environment
190your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.•Never let the brakes “slip” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒ page 214, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine oil ⇒page 224. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 279.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 66. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•Never park where the catalytic converter could come into contact with
dry grass or inflammable materials under the vehicle.•Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never fully drain the fuel tank because the irregularity of the fuel supply may
cause ignition problems. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another brand of fuel.

Liquid coolant losses
Any loss of liquid coolant normally indicates a
leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒page 226, fig. 172 with a
cloth, and carefully unscrew the cap anti-clockwise ⇒.
– Add liquid coolant.
– Screw on the cap tightly.Make sure that the liquid coolant meets the required specifications
⇒page 225, “Liquid coolant”. Do not use a different type of anti-freeze if
anti-freeze G12++ is not available. In this case, use only water and bring the
anti-freeze concentration back up to the correct level as soon as possible.
Always top up with new liquid coolant. Do not fill above the “max” mark. Excess liquid coolant is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of liquid coolant has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The anti-freeze and liquid coolant can be a health hazard. Therefore,
the anti-freeze should be stored in the original container in a safe place out
of reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine – even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•stored heat raises the coolant temperature, or•the hot engine compartment is additionally heated up by the sun.
