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 faster than three quarters of top 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 fric tion 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, the life of the engine will be increased and its oil
consumption reduced.
Running-in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads that have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may cause an accident. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run-in” and do not have the correct friction
properties during the first 200 km. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
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

Connectors
Your vehicle is fitted with a 12-pin co
nnector 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 from any SEAT dealer.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted trailer weight , you can then climb correspondingly
steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 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 co mbination must be reduced by 10% for
every further 1,000 m (or part thereof). The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
The figures for trailer weights and draw bar weights that are given on the
data plate of the towing bracket are for certification purposes only. The
correct figures for your sp ecific model, which may be lower than these figures
for the towing bracket, are given in the registration documents ⇒Section
“Technical data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving. Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•
Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket*Depending on the model version, the ball coupling for the towing bracket may
be found in the tool box.
The ball coupling is provided with in structions on fitting and removing the
ball coupling of the towing bracket.

Think ahead when drivingA vehicle uses most fuel when accelera ting. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.Regular servicingBy taking your car to an Authorised Service Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. A well-
serviced engine gives you the benefit of improved fuel efficiency as well as
maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Check the oil level every time you fill the tank ⇒page 203. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving style, oil consumption can be up to 1 litre per 1,000
km.
Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.
Directly after a cold start, the engine uses about 50-70 litres of fuel per
100 km. This figure then drops to 20 -30 litres per 100 km after about one
kilometre. The engine only reaches its working temperature after about four
kilometres, when fuel consumption will return to a normal level. You should
therefore avoid short journeys.
The ambient temperature has a decisive influence.
The illustration shows the different rates of fuel consumption for the same
distance at both +20°C and -10°C. Your vehicle will use more fuel in winter
than in summer.

tion in litres per 100 km at

WARNING
•
Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle. You must “dry” the brakes by applying the brakes carefully
several times ⇒ page 173, “Braking effect and braking distance”.
Cleaning alloy wheelsEvery two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheels.
Every three months
– Apply a hard wax compound to the wheels.Alloy wheels require regular attention to preserve their appearance. It is
important to remove road salt and brake dust by washing the wheels at
regular intervals, otherwise the finish will be impaired.
Always use an acid-free detergent for alloy wheels.
Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by stone impact, the damaged area should be
repaired immediately.

Underbody sealant
The underside of the vehicle is coated to protect it from corro-
sion and damage.The protective coating could be damage d when driving. We recommend that
the protective coating under the body and on the running gear should be
checked, and reinstated if necessary, before and after the winter season.
We recommend that repair work and addi tional anti-corrosion work is carried
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corros ion coatings to the exhaust pipes,
catalytic converter or the heat shield s on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! This is a fire
hazard.

− 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 may be fatally explosive. Always place the canister on the
ground to fill it.
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− 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 electro-
static 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.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.
PetrolPetrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol, corresponding to the standard DIN EN 228, may be
used for vehicles with catalytic converters (EN = “European Norm”).
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 RON (RON = “research octane number”). You may use petrol with a higher
octane number than the one recommended for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
Even one full tank 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 running behaviour, performance and
service life of the engine. For this reason you should use good quality petrol

containing additives. 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 occur,
the required additives must be added during refuelling.
DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 195.RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply wit h the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for “Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation “ Fatty Acid Methyl Ester” If the date sticker of the vehicle in
cludes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•
The performance of a vehicle using biodiesel maybe somewhat reduced.
•
Fuel consumption of a vehicle using biodiesel may be slightly higher.
•
RME fuel can be used in winter at temperatures down to approx. -10°C.
•
At outside temperatures below -10°C, we recommend using winter diesel
fuel.Caution
•
RME fuel can damage the fuel system in vehicles that are not suitably
adjusted.
•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a biodiesel fuel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.

If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, “winter-grade diesel fuel” is available in some countries during
the cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel sold generally
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade 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 additives) with diesel fuel.
Working in the engine compartmentSafety instructions on working 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 stick 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 200.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 qualified 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 that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 191. The engine compartmen t of any motor vehicle is a
hazardous area ⇒.

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. Otherwis e, 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 249. 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.
•
Always make sure you have not left any objects, such as cleaning cloths
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 cl othing 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 sa fety 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!

If the bonnet is not closed properly, it could open while you are driving and
completely obscure your view of the road. Risk of accident.•
After closing the bonnet, always check that it is properly secured. The
bonnet must be flush with the surrounding body panels.
•
If you notice that the bonnet latch is not secured when the vehicle is
moving, stop the vehicle immediately and close the bonnet properly. Risk
of accident.
Engine oilEngine oil specifications
The engine oil used must conform with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of high quality oil is essential for the correct operation of the
engine and its long useful life, when topping up or replacement is necessary,
use only those oils that conform to the requirements of the VW standards.
If it is not possible to find oil co nforming to the VW standards then oil
conforming to the ACEA or API standa rds with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.
