Starting, changing gears, parking
To park the vehicle
Complete operations only in the sequence given.
● Park the vehicle on a suitable surface ⇒ 
.
● Press and hold the brake pedal until the vehicle comes to a standstill.
● Apply the handbrake firmly ⇒ page 136.
● For an automatic gearbox, move the selector lever to position P.
● Switch off the engine and release the brake pedal.
● Remove the key from the ignition.
● If necessary, turn the steering wheel slightly to lock the steering.
● With a manual gearbox, engage the 1st gear on flat ground and slopes,
or even the reverse gear on hills, and release the clutch pedal.
● Ensure that all passengers leave the vehicle, especially children.
● When leaving the vehicle, take all keys with you.
● Locking the vehicle.
Additional information for steep slopes and hills
Before switching off the engine, rotate the steering wheel so that if the vehi-
cle should move then it will be held by the kerb.
● On slopes, turn the front wheels so that they are against the edge of the
kerb.
● Uphill, turn the wheels towards the centre of the road.
WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
CAUTION
● Special care should be taken when parking in areas with high kerbs or
fixed barriers. Objects protruding from the ground may damage the bumper
or other parts of the vehicle during manoeuvres. To avoid damage, stop be-
fore the wheels touched the barrier or kerb.
● Special attention is required when driving through entrances, over
ramps, kerbs or other objects. The vehicle underbody, bumpers, mudguards
and running gear, and the engine and exhaust system could be damaged as
you drive over these objects. 
Information about the brakes
For the first 200 to 300 km (120 to 190 mph), the new brake pads have not
yet reached their maximum braking capacity, and need to be “run in” first
⇒ 
. The slightly reduced braking effect can be compensated for by in-
creasing pressure on the brake pedal. While running in, the full braking dis-
tance or emergency braking distance is larger then when the brake pads
have been run in. While running in, avoid full power braking or situations
requiring braking performance. For example, in heavy traffic.
The rate of wear of the brake pads depends to a great extent on the condi-
tions in which the vehicle is used and the way the vehicle is driven. If the
vehicle is used frequently in city traffic or for short trips or driven sport style,
visit a Specialised workshop regularly more frequently than advised in the
Maintenance Programme to have the brake pads checked.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). At higher
speed, “dry” the brakes as quickly as possible by braking gently several
times. Only do this without endangering vehicles behind you or any other
road users ⇒

. Before refuelling with natural gas, make sure to add the appropriate
type of fuel.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel tank cap, next to the petrol
filler mouth.
● Unlock the vehicle with the key or with the central locking button  situ-
ated on the driver door ⇒ page 36.
● Press on the rear area of the flap and open it. Refuelling
Problem: If the ambient temperature is very high, the natural gas pump pro-
tection against overheating disconnects this automatically.
●
Remove the plug from the gas filler mouth ⇒ Fig. 108 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank flap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place.
WARNING
Natural gas is a highly explosive, easily flammable substance. Incorrect
handling of the natural gas can cause accidents serious burns and other
injuries.
● Before refuelling with natural gas, the filling mouth must be correctly
engaged. If you can smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury. 

Vehicle care and maintenance
About your tyres and wheels
Fig. 120 Diagram for
changing wheels
The tyres of a vehicle are the components which are subjected to most
stress and are the most underestimated. Tyres are very important, as the
support offered by their narrow surface is the only point of contact between
the vehicle and the road.
The service life of tyres is dependent on tyre pressure, driving style, the care
they receive and the correct fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and our critical to good road holding and safe handling.
Avoiding damage to tyres and wheels
● If you have to drive over a kerb or similar obstacle, drive very slowly and
as near as possible at a right angle to the kerb.
● Inspect the tyres regularly for damage (punctures, cuts, cracks, dents).
● Remove any foreign bodies found on the outside of the tread provided
they have not passed through the wall of the tyre
⇒  page 216.
● The instructions for tyre control systems should always be observed. ●
Replace damaged or worn tyres as soon as possible ⇒ page 216.
● Regularly check tyres for non-visible damage ⇒ page 216.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle ⇒ page 218.
● Do not allow tyres (including the spare wheel) to come into contact with
aggressive substances, grease, oil, fuel or brake fluid ⇒ 
.
● Lost valve caps should be replaced immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been designed to operate best
when rotating in only one direction. An arrow on the tyre sidewall indicates
the direction of rotation on tyres with directional tread ⇒ page 218. Always
observe the direction of rotation indicated when mounting the wheel. This
guarantees optimum grip and helps to avoid aquaplaning, excessive noise
and wear.
If the tyre is mounted in the opposite direction of rotation, drive with ex-
treme caution, as the tyre is no longer being used correctly. This is of partic-
ular importance when the road surface is wet. Change the tyre as soon as
possible or remount it with the correct direction of rotation.
Interchanging tyres
To ensure that the wear is equal on all tyres the wheels should be changed
round from time to time according to the system ⇒ Fig. 120. All the tyres will
then last for about the same time.
SEAT recommends you take the vehicle to a Specialised workshop to have
the tyres changed.
Tyres that are over 6 years old
Tyres are subject to an ageing process as a result of physical and chemical
processes. This may affect their performance. Tyres which are stored for
long periods of time without being used, harden and become more fragile
than tyres which are in constant use.
SEAT recommends that tyres over six years old are replaced with new tyres.
This also applies to tyres (including the spare wheel) which appear to be in 

214Vehicle care and maintenance
Note
If you use tyres that are approved by SEAT, you can be sure that the true tyre
dimensions will be correct for your vehicle. For other tyre models, the tyre
vendor should provide the manufacturer's certificate with the tyre, indicat-
ing that this type of tyre is suitable for your vehicle. This certificate should
always be carried with the vehicle. 
Tyre pressures
Fig. 121 Position of tyre pressure specification plate
The correct tyre pressures for tyres fitted at the factory is shown on a label
and is valid for summer and winter tyres. This label ⇒ Fig. 121 is either in
the driver door strut or inside the fuel cap.
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the vehicle's handling ⇒ 
. It is essential to maintain the
correct tyre pressures, especially if driving at high speeds. Incorrect tyre
pressure causes premature wear and could cause tyre blow-out. The pressure should therefore be checked at least once a month and before
starting a journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are
hot, the pressures are greater.
Never deflate a hot tyre in order to obtain the required pressure. This could
result in very low tyre pressures which may lead to sudden blow-outs. 

215
Vehicle care and maintenance
Checking tyre pressures
Check tyre pressures only when the vehicle has not been driven for more
than a few kilometres at low speeds in the past three hours.
● Check tyre pressures regularly, and only when the tyres are cold. Always
check all tyres, including the spare wheel. Check tyre pressures more often
in colder regions, and only when the vehicle has not been driven recently.
Always use a correctly-operating tyre gauge.
● Adjust tyre pressures to the loads carried in the vehicle.
● After adjusting the tyre pressure, check that the caps are properly
screwed.
The spare wheel or temporary spare wheel must be at the maximum pres-
sure specified.
WARNING
If tyre pressures are too high or too low, the tyre may deflate or burst
suddenly while driving. This could result in serious accident.
● If the tyre pressure is too low, the tyres could overheat, resulting in
tread detachment or even burst tyres.
● When driving at high speeds and/or fully loaded, the tyre could sud-
denly overheat, burst or be subject to tread detachment, with the resul-
tant loss of control of the vehicle.
● Tyre pressures which are too high or too low reduce the service life of
the tyre, affecting the vehicle's performance.
● Tyre pressures should be checked regularly, at least once a month
and before long journeys.
● Adjust the pressures of all the tyres to the vehicle load.
● Never deflate excess pressure from hot tyres.
CAUTION
● Take care not to tilt the manometer when placing it on the valve. Other-
wise, the valve may be damaged.
● To avoid damage to the valves, always replace valve caps correctly.
Check that the caps are identical to the standard caps and have been cor-
rectly tightened.
For the sake of the environment
Under-inflated tyres will increase the fuel consumption. 
Tread depth and wear indicators
Fig. 122 Tyre tread:
tread wear indicators
Tread depth
Certain driving conditions require a deeper tread, as well as needing the
tread to be approximately the same on the front and rear tyres. This is par-
ticularly important when driving in winter, in cold temperatures and on wet
roads ⇒

Vehicle care and maintenance
Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil ⇒ page 185.
● Do not tow-start the vehicle; use the starter cables ⇒ page 273.
If you should notice misfiring, uneven running or loss of power when the ve-
hicle is moving, reduce speed immediately. Have the vehicle inspected by a
Specialised workshop. If this happens, unburnt fuel can enter the exhaust
gas system and escape into the atmosphere. The catalytic converter can al-
so be damaged by overheating.
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. 

Practical information
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. When the engine is running, disconnect the leads in reverse or- der 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 182.
● 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, dan-
ger of explosion. Failure to comply could result in an explosion.
WARNING (Continued)
● 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. 
