Practical tips
Te c h n i c a l D a t a
•
The engine compartment is a dangerous area! Before you open the
bonnet to work on the engine or in the engine compartment, you must
switch the engine off and allo w it to cool to reduce the risk of scalding or
other kind of injuries. Read and observe the relevant warnings
⇒ page 205.Note
•
The appropriate warning lamp for a fault will light up in vehicles without
warning or information texts in the display.
•
In vehicles with warning or information texts on the screen, the appro-
priate warning lamp for a fault will ligh t up and a warning or information text
will also appear on the screen.
Fuel level / reserve

This symbol lights up to indicate that the fuel tank under the
reserve level.It lights up when only 7 litres of fuel remain in the tank. Also, an audible
warning is given. It reminds you to fuel up the fuel tank as soon as possible
⇒ page 202.
The instrument panel displ ays the following message
8): PLEASE REFUEL! .
Coolant Level* / temperature

The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.There is a fault if:•
The warning symbol does not go out again after a few seconds.
•
The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals ⇒ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
The instrument panel disp lays the following message
9): CHECK COOLANT
INSTRUCTIONS MANUAL ⇒ page 212.
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the over heating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 239.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch the engine off . Contact an Authorised Service Centre
or a qualified workshop.
Coolant level too low

Heating, Ventilation and Air conditioning
146
– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The outside temperature is below +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpl easant smells from coming from the outside.

Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning sy
stem cannot be switched on this may be caused by
the following reasons:
•
The engine is not running.
•
The button is disconnected.
•
The outside temperature is below +3°C.
•
The air conditioning syst em compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.Caution
•
If you suspect that the air conditioning is damaged, switch it off with the button to prevent further damage and have it checked by a qualified
workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend you to take the vehicle to a qualified
workshop.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath the vehicle. This is completely normal and there is no need to
suspect a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this pu rpose. Therefore, do not cover these
slots with items of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has been over-
heated by sun, the air in side can be cooled quicklier by opening the windows
for a short time.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
It is advisable to connect the air conditioning at least once a month, to
lubricate the system gasket s and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

Driving
158If the engine does not start immediately, switch the starter off after
10 seconds and try again after half a minute . If the engine still does not start,
the fuel pump fuse should be checked ⇒page 239, “Fuses”.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should av oid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.
•
The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter th e catalytic converter and damage it.
•
Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the batte ry of another vehicle. Note and follow
the instructions ⇒page 253, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.
Starting diesel engines
The engine can only be started using a genuine SEAT key with
its correct code.– Move the gear lever to the ne utral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 156, fig. 118 . The
indication lamp

will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position to start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the starter motor must not be allowed to run on with the engine.
When starting a very cold engine, it may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see ⇒page 253.
Glow plug system for the diesel engine
To avoid unnecessary discharging of th e battery, do not use any other major
electrical equipment while th e glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 76 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal
(up to one minute) to start the engine after refuelling with diesel fuel. This is
because the system must eliminate air first.

Fuse cover underneath the steering wheel
– Switch off the ignition and the component concerned.
– Identify the fuse corresponding to the damaged electric consumer ⇒page 242.
– Take the plastic clip from inside the fuse cover, fit it onto the
blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
Fuse cover in engine compartment
– Switch off the ignition and its failed electrical component.
– Prise off the fuse cover in the engine compartment by pressing the tabs towards the centre of the cover ⇒page 239, fig. 157 .
– Identify the fuse for the failed component ⇒page 242.
– Take the plastic clip from inside the fuse cover (at left-hand end of the dash panel), fit it onto the blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
– Carefully fit the fuse cover back on to ensure no water can enter
the fuse box.The individual electrical circuits are pr otected by fuses. The fuses are located
behind a cover at the left-hand end of the dash panel and on the left-hand
side of the engine compartment. The electric windows are protected by circuit breakers
. These reset automat-
ically after a few seconds when the ov erload (caused for example by frozen
windows) has been corrected.
