Unleaded petrol
Refuel only using unleaded petrol ⇒ page 154, Catalytic converter in petrol
engine vehicles. Automobile associations will provide information regarding
the network of petrol stations offering unleaded petrol. 
Headlights
Your dipped beam headlights are adjusted in an asymmetrical formation.
The side of the road on which you are driving is illuminated more brightly.
If you are driving in a foreign country where traffic drives on the opposite
side of the road this will dazzle the oncoming traffic. In order to avoid daz-
zling oncoming traffic, it is essential to have the headlights adjusted at an
authorised SEAT dealer.
Note
You will receive information about the modification of the headlights at an
authorised SEAT dealer. 
Preventing damage to the vehicle
In order to prevent damage to the vehicle, take special care:
● on roads in poor condition
● when mounting the kerb
● when approaching very steep ramps, etc.
● with the parts of the vehicle situated on the lower part of the vehicle, i.e.
the spoiler, the exhaust pipe, This applies especially to vehicles with a very low suspension (sport) and
when the vehicle is fully loaded.

Driving through water
Fig. 114 Driving through
water
To prevent the vehicle from being damaged when driving through water (i.e.
flooded roads), please observe the following:
● Determine the depth of the water before entering. The water can reach a
maximum height of below the door sill ⇒ Fig. 114.
● Drive at a maximum pace of walking speed. Driving at a higher speed
can cause a wave in front of the vehicle, which can cause water to enter the
engine air intake system or other parts of the vehicle.
● Never stop in the water, never reverse and never stop the engine.
● Before driving through water deactivate the START-STOP system

Technical requirements
If your vehicle has a factory-fitted towing bracket or is equipped with a se-
lection of SEAT Original Accessories, it meets all the relevant technical and
legal requirements.
In vehicles with a towing bracket it is possible to remove the ball joint, situ-
ated (together with the special assembly instructions) in the housing for the
spare wheel in the vehicle luggage compartment ⇒ page 198, Vehicle tool
kit*.
Your vehicle is fitted with a 13-pole power socket for the electrical connec-
tion between the trailer and the vehicle. If the trailer you are going to use
has a 7-pin connector, the corresponding adaptor, acquired from the SEAT
Original Accessories Catalogue, can be used.
If a towing bracket is to be retro-fitted to the car, it must be done according
to the instructions of the towing bracket manufacturer.
Note
Any queries that may arise can be directed to an authorised SEAT dealer. 
Trailer weight
Trailer weight
The combined vehicle and trailer must be balanced. To do so use the maxi-
mum permitted towing bracket load. An insufficient weight exerted by the trailer drawbar on the ball joint of the towing bracket will have a negative
impact upon the response of the vehicle-trailer assembly on the road.
Weight distribution
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Ensure that the objects do not move.
If the towing vehicle is empty and the trailer loaded then the load distribu-
tion is incorrect. However, if these conditions cannot be avoided, drive very
slowly.
Tyre pressure values
Correct the tyre pressure in your vehicle to “total load” ⇒ 
page 188, Tyre
useful life.
Trailer weight
Never exceed the authorised trailer weight under any circumstances
⇒  page 226, Description of the data.
The trailer weights listed are only applicable for altitudes up to 1000 m
above sea level. Due to a lower air density the engine power decreases de-
pending on the increase in altitude, this also causes the climbing ability to
decrease, which requires a reduction of the weight of the vehicle with a
trailer by 10 % for every 1000 m increase in altitude. The weight of the as-
sembly is calculated by adding the vehicle weight (loaded) to the trailer
weight (loaded). Always drive with special care when towing a trailer.
The towed load and support load information that is displayed on the tow-
ing bracket manufacturers label are only values for the verification of the
device. The correct figures for your specific vehicle, which are usually lower
than these figures, are given in the documentation of your vehicle. 

Driving the vehicle with a trailer
WARNING
● Adjust your speed to suit the road and traffic conditions.
● An electrical installation that is connected incorrectly or by non-spe-
cialised personnel can prevent the connection of the current to the trailer
and cause faults in the electrical system operation throughout the entire
vehicle, leading to accidents and serious injury.
● All electrical work must be carried out only by the specialised serv-
ices.
● Never directly connect the trailer electrical device to the electrical
sockets of the reverse driving lights or other sources of electrical current.
CAUTION
● Avoid corners, and sudden and sharp braking.
● Once the trailing arm has been removed, place the corresponding cover
on the hole of the fastening point. This prevents dirt from entering the hole
– see the trailer system assembly manual.
Note
● In the event of frequent journeys with a trailer, we recommend also hav-
ing the vehicle inspected in-between the service intervals.
● When connecting and disconnecting the trailer, the handbrake must be
applied.
● For technical reasons, trailers with LED reverse lights cannot be incorpo-
rated into the vehicle anti-theft alarm system. 

WARNING
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Risk of scalding! Wait until no steam or
coolant can be seen before opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Engage neutral in vehicles with manual gearbox and move the selec-
tor lever to position P in vehicles with automatic gearbox.
● Apply the handbrake firmly.
● Wait for the engine to cool down.
● For safety reasons, the bonnet must always be closed when the vehi-
cle is moving. Therefore, after closing the bonnet always check that it is
properly secured.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet prop-
erly. Risk of accident!
● Keep children away from the engine compartment.
● Do not touch hot engine parts. Risk of burns!
● Never spill fluids on hot engine compartments. These fluids can
cause a fire (e.g. antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan when the engine is hot. The fan may start
running suddenly!
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure!
● Protect face, hands and arms from any hot steam or hot coolant re-
leased by covering the cap with a large, thick rag when opening the ex-
pansion tank.
● Do not leave any objects, such as cloths and tools, in the engine com-
partment.WARNING (Continued)
● When working underneath the vehicle, secure it so that it cannot roll
away and support it safely on suitable supports. The hydraulic jack is not
sufficient for this purpose. Risk of injuries!
● If any tests have to be performed with the engine running, there is an
extra safety risk from rotating parts, such as the drive belt, alternator
and radiator fan, etc., and from the high-voltage ignition system. You
should also note the following:
–Never touch the electrical wiring of the ignition system.
– Keep away from moving engine parts when wearing jewellery,
loose clothing or long hair. Risk of fatal injuries! All jewellery must be
removed, hair tied back and close-fitting clothing worn.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary.
–Always disconnect the battery from the onboard network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
● When topping up fluids, make sure the correct fluid is put into the cor-
rect filler opening. Otherwise this can cause serious malfunctions or engine
damage!
● Never open the bonnet using the release catch. Risk of damage.
For the sake of the environment
Due to the environment-friendly disposal of fluids, the equipment necessary
and the knowledge required, fluids must be changed by an authorised SEAT
dealer during the service inspections of the vehicle. 

Coolant
General notes
The cooling system is factory-filled with an anti-freeze product.
Coolant consists of a mixture of water and 40% anti-freeze additive. This
mixture gives the required anti-freeze protection at temperatures down to
-25 °C (-13 °F) and protects the cooling and heating system against corro-
sion. It also prevents scaling and raises the boiling point of the coolant con-
siderably.
The coolant concentration must not be reduced by adding water, even in
warmer seasons or in warm countries. The concentration of the anti-freeze
additive in the coolant must be at least 40 %.
If greater anti-freeze protection is required in very cold climates, the propor-
tion of the anti-freeze additive can be increased, but only up to 60 % (anti-
freeze protection down to approx. -40 °C (-40 °F)). Any excess in this propor-
tion would reduce the anti-freeze protection and affect the cooling effect.
Vehicles in countries with a cold climate are supplied with coolant protec-
tion down to around -35 °C (-31 °F). The proportion of anti-freeze additive in
these countries should always be at least 50 %.
The type of anti-freeze to be used for topping up is indicated on the coolant
tank cover ⇒ Fig. 119.

Diesel enginesTop-up quantity (in litres)1.6 l/77 kW TDI CR6,5
CAUTION
● Anti-freeze that does not correspond to the correct specification may
particularly affect corrosion protection considerably.
● Faults caused by corrosion may lead to coolant leaks. Risk of serious en-
gine faults! 

Checking and refilling levels
Incorrect handling of the vehicle battery could lead to damage. We therefore
recommend all work on the vehicle battery be performed by an authorised
SEAT dealer.
Always be aware of the danger of injury and scalding as well as the risk of
accident or fire when working on the battery and the electrical system.
Therefore, always observe the warnings and follow all general safety pre-
cautions.
WARNING
● Battery acid is very corrosive, therefore, the battery must be handled
with the utmost care. Wear protective gloves and protect your eyes and
skin when handling batteries. The corrosive fumes in the air irritate and
inflame the respiratory tract and cause conjunctivitis. It corrodes tooth
enamel and causes deep, difficult-to-heal wounds when in contact with
the skin. Repeated contact with diluted acids causes skin disease (in-
flammation, ulcers and fissures). When in contact with water, acids dilute
and develop a great deal of heat.
● Do not tilt the battery, as acid could leak out of the vapour vents. Pro-
tect your eyes with glasses or a protective helmet! Risk of blindness! If
acid should splash into the eyes, rinse the affected eye immediately for
several minutes using clean water. Then seek medical care immediately.
● Neutralize any acid splashes on the skin or clothing with soap solu-
tion as quickly as possible and rinse off with plenty of water. If acid is
swallowed by mistake, consult a doctor immediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explosive mixture of gases is gen-
erated when the battery is under charge. Sparks when disconnecting or
releasing cable terminals with the ignition switched on could also cause
an explosion.
● A short circuit is produced if the battery terminals are bridged, e.g.
using metal objects, cables, etc. Possible consequences of a short cir-
cuit: melting of lead plates, battery explosion and fire, splashing acid.
WARNING (Continued)
● The following is forbidden while working on the battery: fire and open
flames, smoking and activities that could produce sparks. Avoid causing
sparks when handling cables or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all electrical components and disconnect the cable
from the negative terminal (-) of the battery. To change a bulb, simply
switch off the corresponding light.
● Never charge a frozen or thawed out battery. Risk of explosion and
acid burns! Replace a frozen battery.
● Never use the jump leads on batteries in which the electrolyte level is
too low. Risk of explosion and acid burns.
● Never use a damaged battery. Risk of explosion! Replace a damaged
battery immediately.
CAUTION
● Never disconnect the battery when the ignition is switched on, as the
electrical system (electronic components) of the vehicle could be damaged.
When disconnecting the battery from the vehicle electrical system, discon-
nect its negative terminal (-) first. Only then may the positive terminal (+) be
disconnected.
● When connecting the battery, connect the positive terminal (+) first. On-
ly then may the negative terminal (-) be connected. The battery cables must
never be connected to the wrong battery terminals. Risk of burning the elec-
trical installation.
● Make sure the battery acid does not come into contact with the body-
work. Risk of paintwork damage.
● Do not expose the battery to direct sunlight to protect it from ultraviolet
radiation. 

Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems. 
Changing the battery
A replacement battery must have the same capacity, voltage, current rating
and size as the original. The appropriate types of battery can be acquired
from authorised SEAT dealers.
We recommend having the battery changed by an authorised SEAT dealer,
where the new battery will be correctly installed and the original disposed
of in line with regulations. 
Automatic disconnection of electrical equipment
When heavily-charging a battery, the programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket.
Note
Despite any measures taken by the control unit, the battery could drain. e.g.
with the engine is switched off, the key is turned in the ignition for a long
period or the side lights or parking lights are switched on. The switching off
of certain electrical components does not impair driving comfort and the
driver will often not even realise. 

Introduction
WARNING
● During the first 500 km (300 miles), new tyres do not give maximum
grip, therefore you should drive carefully. Risk of accident!
● Never drive with damaged tyres. Risk of accident!
● Only use wheels and tyres that been authorised by SEAT or your vehi-
cle model. Failure to do so could impair road safety. Risk of accident!
● Never exceed the maximum speed permitted for your tyres. Risk of ac-
cident due to tyre damage and loss of vehicle control.
● Under-inflated tyres are submitted to greater rolling resistance. This
means that they can overheat at high speeds. This can cause tread sepa-
ration and even tyre blow-out.
● For driving safety, tyres should be replaced at least in pairs according
to the axle and not individually. The tyres with the deepest tread should
always be used on the front wheels.
● Never fit used tyres of an unknown age or prior use.
● Tyres must be immediately changed at the very latest when they have
worn down to the tread wear indicators.
● Worn tyres reduce the necessary grip at high speeds on damp surfa-
ces. This could lead to “aquaplaning” (uncontrolled vehicle movement –
“skidding” on damp surfaces).
● Damaged wheels and tyres must be replaced immediately.
WARNING (Continued)
● Do not use summer or winter tyres that are more than 6 or 4 years old
respectively.
● Wheel bolts should be clean and screw easily. However, they must
never be treated with grease or oil.
● If the tightening torque of the wheel bolts is too low, they could loos-
en while the vehicle is moving. Risk of accident! If the tightening torque
of the wheel bolts is too high, the bolts and threads could be damaged,
leading to the permanent deforming of the rim support surfaces.
● Incorrectly handled wheel bolts could lead to a wheel coming loose
while the vehicle is moving. Risk of accident!
● The local regulations in force must be taken into account when using
child seats.
CAUTION
● Where a spare wheel that is not compatible with the wheels fitted is
used, follow the instructions ⇒ page 190.
● The prescribed tightening torque for wheel bolts on steel and alloy
wheels is 120 Nm.
● Protect your tyres from coming into contact with oil, grease and fuel.
● Replace any lost valve caps immediately.
For the sake of the environment
Under-inflated tyres increases fuel consumption. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

190Wheels and tyres
The manufacturing date is also indicated on the tyre sidewall (possibly only
on the inner side of the wheel). DOT … 27 12…
means, for example, that the tyre was produced in the 27th week of 2012.
Follow the instructions ⇒ page 190 if you only have a temporary spare
wheel. 
Tyres with directional tread pattern
The direction of rotation is indicated by the arrows on the tyre sidewall. The
direction of rotation indicated must be respected. This guarantees optimum
grip and helps avoid excessive noise, wear and aquaplaning.
In the event of a flat tyre, a spare wheel with an undetermined tread pattern
or an opposite tread pattern must be used and you must drive carefully, as
in these cases the tyres no longer offer maximum performance. Spare wheelFig. 126 Luggage com-
partment: spare wheel
The spare wheel is housed in a well under the floor panel in the luggage
compartment and is secured by a special bolt ⇒ Fig. 126.
Take out the tool box before removing the spare wheel.
The tyre pressure of the spare wheel must be checked (preferably whenever
the tyre pressure is checked – see sticker on fuel tank flap ⇒ page 188) to
ensure the spare wheel remains ready for use.
If the spare wheel is not the same size or design as the tyres that are moun-
ted on the car (for example if the car has winter tyres or tyres with direction
tread), only use the spare tyre for a short period of time in the event of
breakdown and drive with the corresponding care ⇒ 
.
It must be replaced as soon as possible for a wheel with a normal size and
finish.
Temporary spare wheel
If the vehicle is equipped with a temporary spare wheel, there will be a
warning sign on the rim of the wheel. 
