Driving
164If 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 254, “Fuses”.
WARNING
•Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon monoxide, 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 avoid 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 the 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 battery of another vehicle. Note and follow
the instructions in ⇒page 267, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle stationary.
Start off immediately, driving gently. 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 neutral 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 162, fig. 117 . The
indicator lamp
D 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 the ⇒ page 267.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 83 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run 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.

temperature increases due to the heat accumulated in the engine compart-
ment or due to its prolonged exposure to solar radiation.
WARNING
•Never switch the engine off until the vehicle is completely stationary.•The brake servo works only when the engine is running. With the
engine switched off, more strength is needed to brake. As normal brake
operation cannot be performed, risk of accidents and serious injury may
exist.•The steering lock can be immediately blocked once the key is removed
from the ignition. The steering wheel cannot be turned. Risk of accident.Caution
When the engine has been running under a heavy load for a long period, heat
can accumulate in the engine compartment and cause engine damage. For
this reason, you should idle the engine for approx. 2 minutes before you
switch it off.

Driving and the environment
194change down into a lower gear or range (depending on the type of trans-
mission). This makes use of engine braking and relieves the brakes.•Never let the brakes “drag” 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.•If the brake fluid loses its viscosity and is subjected to heavy use,
vapour bubbles can form in the brake system. This reduces the efficiency of
the brakes.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Before purchasing accessories please
observe the relevant instructions ⇒page 212, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages the catalytic converter.
– Do not let the fuel get too low in the tank. – For engine oil changes, do not replenish with too much engine oil
⇒page 226, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 267.
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 specialised workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.•Never park where the catalytic converter could come into contact with
dry grass or flammable 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 run the fuel tank completely dry 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 gas under some conditions. This depends

Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter diesel which is safe to
-15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.Working in the engine compartmentSafety instructions on workin
g in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle. 6. Raise the bonnet
⇒page 223.
You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason, we recommend you to have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 212. The engine compartment of the vehicle is a
hazardous area ⇒.
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves a risk 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 lever 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 268. The battery could
explode.

11. Turn on the heater blower and heated rear window in the vehicle
with the flat battery. This helps minimise voltage peaks which are
generated when the leads are disconnected.
12. When the engine is running, disconnect the leads in reverse order to the details given above.Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
•Please note the safety warnings referring to working in the engine
compartment ⇒page 221, “Working in the engine compartment”.•The battery providing assistance must have the same voltage as the flat
battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.•Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.•Keep sparks, flames and lighted cigarettes away from batteries, danger
of explosion. Failure to comply could result in an explosion.•Observe the instructions provided by the manufacturer of the jump
leads.•Do not connect the negative cable from the other vehicle directly to the
negative terminal of the flat battery. The gas emitted from the battery could
be ignited by sparks. Danger of explosion.•Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
•The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.•Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.•Do not bend over the batteries. This could result in chemical burns.Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
