Emission control system* 
This warning lamp monitors the exhaust system.
Warning lamp  flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
Warning lamp  is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest specialised workshop to have the engine checked. 
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, and
three acoustic warning signals ⇒ 
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 223. 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 specialised workshop.
Coolant level too low
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down . First check the coolant level. If the level of the cool-
ant is below the “MIN” mark, top up with coolant liquid ⇒ 
.
WARNING
● If your vehicle is immobilised for technical reasons, move it to a safe
distance from traffic. Turn the engine off, turn the hazard lights on and
place the warning triangle.
● Never open the bonnet if you can see or hear steam or coolant escap-
ing from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
● The engine compartment is a dangerous area! Before carrying out any
work in the engine compartment, switch off the engine and allow it to
cool down. Always note the corresponding warnings ⇒ page 193.

Alternator 
This warning lamp signals a fault in the alternator.
The warning lamp  lights up when the ignition is switched on. It should
go out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery. 

Lights and visibility
For the sake of the environment
The heated rear window should be disconnected as soon as the glass is
demisted. By saving electrical power you can also save fuel.
Note
To avoid possible damage to the battery, an automatic temporary discon-
nection of this function is possible, coming back on when normal operating
conditions are re-established. 
Hazard warning lights 
The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.
Fig. 58 Centre console:
switch for hazard warn-
ing lights
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving traffic. 2. Press the button to switch on the hazard warning lights
⇒ 
.
3. Switch the engine off.
4. Apply the handbrake.
5. On a manual gearbox engage 1st gear. On an automatic, move the selector lever to P.
6. Use the warning triangle to draw the attention of other road users to your vehicle.
7. Always take the vehicle key with you when you leave the vehi- cle.
Switch on the hazard warning lights to warn other road users, for example
when:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. That is that the two turn signal turn signal lamps   and the
turn signal lamp in the switch  will flash at the same time. The hazard
warning lights also work when the ignition is switched off.
WARNING
● The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
● Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire! 

Starting and stopping the engine
Starting petrol 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 start-
er to turn the engine on.
– Turn the ignition key to the starting position ⇒ page 136.
– Let go of the ignition key as soon as the engine starts; the start-
er motor must not run on with the engine.
After starting a very hot engine, you may need to slightly press down the ac-
celerator.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine does not start immediately, switch the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 223, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust fumes contain carbon monoxide, an odourless and colourless poi-
sonous 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 fol-
low the instructions in ⇒ page 240, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. 

Driving
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 start-
er to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒ fig. 98 2
. The indicator
lamp  will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position 3
to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the start-
er 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 sec-
onds 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 240.
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 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.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust fumes contain carbon monoxide, an odourless and colourless poi-
sonous 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 fol-
low the instructions in ⇒ page 240, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. You should drive off as soon as you start the engine. This helps the en-
gine reach operating temperature faster and reduces emissions. 
Switching off the engine
– Stop the vehicle.
– Turn the ignition key to position ⇒ fig. 98 1
.
After switching the engine off, the radiator fan may run on for up to 10 mi-
nutes. It is also possible that the fan turns itself on once more if the coolant 

Driving and the environment
WARNING (Continued)
● 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 range (depending on the type of
transmission). 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, va-
pour 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 183, Technical modifi-
cations.
● If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessa-
ry journeys.

Exhaust gas purification system Catalytic 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 198, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 240.
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 61. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. 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 sys-
tem. 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
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

Driving and the environment
Driving abroad Observations
To drive abroad, the following must be taken into consideration:
● For vehicles fitted with a catalytic converter ensure that unleaded petrol
is available for the journey. See the chapter “Refuelling”. Automobile organ-
isations will have information about service station networks selling unlea-
ded fuel.
● In some countries, it is possible that your vehicle model is not sold, and
therefore spare parts are not available or the Authorised Services can only
carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparations that you vehicle requires and also about necessary
maintenance and repair possibilities. 
Adhesive strips for headlights
If you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the head-
light lenses. Further information is available at your Authorised Service Cen-
tre.
In vehicles with adaptive headlights, the rotation system must previously be
disconnected. To do this, please go to a specialised workshop. Trailer towing
What do you need to bear in mind when towing a trailer?
Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. If you wish to retrofit a towing bracket, consult
⇒ page 185.
Connectors
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available in any SEAT dealer.
Trailer weight / drawbar load
Never exceed the authorised trailer weight. If you do not load the trailer up
to the maximum permitted trailer weight, you can then climb correspond-
ingly steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every further 1000 m (or part thereof). The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
When possible, operate the trailer with the maximum permitted drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit. 

180Vehicle 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 Authorised Service Centre has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recom-
mend 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 193.
● 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 brakes may affect braking efficiency.
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 Plastic parts and dash panel cleaning
– Use a clean, damp cloth to clean plastic parts and the dash
panel.
– If this does not provide satisfactory results, use a special sol-
vent-free plastic cleaning product. 

WARNING
● Fuel is highly flammable and can cause serious burns and other inju-
ries.
–Never smoke or use an open flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion haz-
ard.
– Follow legal requirements for the use of spare fuel canisters.
– For safety reasons we do not recommend carrying a spare fuel can-
ister in the vehicle. The canister could be damaged in an accident and
leak.
● If, in exceptional circumstances, you have to carry a spare fuel canis-
ter, please observe the following points:
–Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes
to ignite. This could cause an explosion. Always place the canister on
the ground to fill it.
– Insert the fuel nozzle into the mouth of the canister as far as possi-
ble.
– If the spare fuel canister is made of metal, the filling nozzle must
be in contact with the canister during filling. This helps prevent an
electrostatic charge building up.
– Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
CAUTION
● Fuel spills should be removed from the paintwork immediately.
● Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.
● When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine the ignition must be switched on for at least 30 sec-
onds without starting the engine. When you then start the engine it may take longer than normal (up to one minute) for the engine to start firing.
This is due to the fact that the fuel system has to purge itself of air before
starting.
For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched
off; this may cause the fuel to overflow if it becomes warm. 

192Checking and refilling levels
Petrol
Petrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol conforming to standard DIN EN 228 may be used for
vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Research Octane Number”, unit for determining the knock resistance of
petrol). You may use petrol with a higher octane number than the one rec-
ommended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
CAUTION
● Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
● High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.
For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter. 
Petrol additives
Petrol additives improve the quality of the petrol.
The quality of the petrol influences the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi- tives. These additives will help to prevent corrosion, keep the fuel system
clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems oc-
cur, the required additives must be added during refuelling.

Diesel Diesel*
Diesel fuel must conform to DIN EN 590 (EN = “European Standard”). It
must have a cetane number (CN) of at least 51. The cetane number indi-
cates the ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 187. 
Biodiesel*
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by
the diesel manufacturer in accordance with standard EN 590 or DIN 51628
is authorised and will not cause damage to the engine or the fuel system.
● The diesel engine has been designed to be used exclusively with diesel
fuel conforming to standard EN 590. Never refuel or use petrol, kerosene,
fuel oil or any other type of fuel. If you accidentally fill up the vehicle with
the wrong type of fuel, do not start the engine. Seek assistance from speci-
alised personnel. The composition of these fuels may severely damage the
fuel system and the engine. 

198Checking and refilling levels
–Wait two minutes.
– Pull out the dipstick. Wipe the dipstick with a clean cloth and
insert it again, pushing it in as far as it will go.
– Then pull it out once more and check the oil level ⇒ fig. 124.
Top up with engine oil if necessary.
Oil level in area A
Do not add oil.
Oil level in area B
Oil
can be topped up. The indicated oil level should be after in zone A
Oil level in area COil
must be topped up. The indicated oil level should be after in zone
A
Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely
to be higher for the first 5000 km. For this reason the engine oil level must
be checked at regular intervals, preferably when filling the tank and before
a journey.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 193.
CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact an Authorised
Service Centre. 

in
Safety instructions on working in the engine compartment on
page 193.
– Unscrew cap from oil filler opening ⇒ fig. 125.
– Top-up oil in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using
small quantities, wait a while and check the oil level before
adding any more oil.
– As soon as the oil level is in area B
, carefully close the cap.
