The distance covered is displayed in “kilometres” or miles “m”. It is possi-
ble to change the measurement units (kilometres “km”/miles “m”) in the
radio/Easy Connect*. Please refer to the Easy Connect* Instruction Manual
for more details.
Odometer/trip recorder
The odometer shows the total distance covered by the vehicle.
The trip recorder shows the distance that has been travelled since it was
last reset. It is used to measure short trips. The last digit of the trip recorder
indicates distances of 100 metres or tenths of a mile.
The trip recorder can be set to zero by pressing 0.0/SET

⇒  Fig. 40.
Fault display
If there is a fault in the instrument panel, the letters DEF will appear in the
trip recorder display. Have the fault repaired immediately, as far as is possi-
ble. Fuel level
The display
6 ⇒ Fig. 38 only works when the ignition is switched on. When
the display reaches the reserve mark, the lower diode lights up in red and
the control lamp  appears ⇒ page 248. When the fuel level is very low,
the lower diode flashes in red.
The distance to empty fuel level is displayed on the instrument panel 3
⇒ Fig. 38.
The capacity of the fuel tank of your vehicle is given in the Technical data
section ⇒ page 323.
In natural gas engines
The yellow warning lamp
 lights up when both fuel types (petrol and natu-
ral gas) have reached reserve level.
The green control lamp  comes on when the vehicle is working with natural
gas.
The green control lamp  switches off when the natural gas is exhausted.
The engine changes to operate with petrol.
Thing to note: If the vehicle is left parked for a long time immediately after
refuelling, the natural gas level indicator may not accurately indicate the
same level shown after refuelling when the vehicle is started up again. This
is not due to a leak in the system, but to a drop in pressure in the gas tank
for technical reasons after a cooling phase immediately after refuelling.
CAUTION
Never run the fuel tank completely dry. An irregular fuel supply could cause
misfiring. In this way the unburned fuel can reach the exhaust system,
which could cause the catalytic converter to overheat resulting in damage. 

WARNING
People who, because of medications, paralysis or chronic diseases (e.g.
diabetes) cannot perceive pain or temperature, or have a limited percep-
tion thereof, may suffer burns to the back, buttocks or legs when using
seat heating, an occurrence that may entail a very lengthy recovery peri-
od or from which it may not be possible to recover fully. Seek medical ad-
vice if you have doubts regarding your health.
● People with a limit pain and temperature threshold must never use
seat heating.
WARNING
If the fabric of the cushion is wet, this can adversely affect the operation
of the seat heating, increasing the risk of burns.
● Make sure the seat cushion is dry prior to using the seat heater.
● Do not sit on the seat with clothing that is wet or damp.

Driver assistance systems
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 
Tyre monitor indicator warning lamp
lights upPossible causeSolution

The pressure in one or more
tyres has clearly reduced in
comparison to the tyre pres-
sure set by the driver or the
tyre has structural damage.
Additionally, an audible warn-
ing can be heard and a text
message can be seen on the
instrument panel display. Stop the vehicle! Reduce
speed immediately! Stop the
vehicle safely as soon as pos-
sible. Avoid sudden manoeu-
vres and braking! Check all
tyres and pressures. Replace
any damaged tyres.
flashesPossible causeSolution

System malfunction. The con-
trol lamp flashes for about one
minute and then lights up per-
manently.
If the tyre pressure is correct,
switch the ignition off and on
again. If the control lamp re-
mains lit up, the tyre monitor-
ing indicator can be calibra-
ted. Have the system reviewed
by a specialised workshop.
Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while the function is verified. They will switch off after a
few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may be damaged resulting in a loss of control of the
vehicle and a serious or fatal accident.
● If the warning lamp  lights up, stop immediately and check the
tyres.
● If the tyres are inflated at different pressures or if a tyre pressure is
too low, this will increase tyre wear, negatively affecting vehicle stability
and increasing braking distances.
● If tyres are inflated at different pressures or a tyre pressure is too low,
a tyre may be damaged and burst resulting in a loss of control of the ve-
hicle.
● The driver is responsible for ensuring that all of the vehicle tyres are
correctly inflated to the right pressure. The recommended tyre pressure
is indicated on the label ⇒ page 307.
● The tyre monitoring system can only operate correctly if all of the
tyres are inflated to the correct pressure when cold. 

232Driving and the environment
Reduce idling time
In vehicles with the Start-Stop system idling is automatically reduced. In ve-
hicles without the Start-Stop system it is worth switching off the engine, for
example, at level crossings and at traffic lights that remain red for long peri-
ods of time. When an engine has reached operating temperature, and de-
pending on the cylinder capacity, keeping it switched off for a minimum of
about 5 seconds already saves more than the amount of fuel necessary for
restarting.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even before the engine is started. 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.
Avoid short journeys
The engine and catalytic converter need to reach their optimal operating
temperature in order to minimise fuel consumption and emissions.
A cold engine consumes a disproportionate amount of fuel. The engine only
reaches its working temperature after about four kilometres (2.5 miles),
when fuel consumption will return to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the correct pressures
⇒ page 265 to save fuel. If the pressure is below half bar, fuel consumption
may increase by 5%. Due to the greater rolling resistance, under-inflation
also increases tyre wear and impairs handling.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%. Avoid carrying unnecessary loads
Given that every kilo of
extra weight will increase the fuel consumption, it is
advisable to always check the luggage compartment to make sure that no
unnecessary loads are being transported.
Since the luggage rack increases the aerodynamic drag of the vehicle, you
should remove it when not needed. This will save, at a speed of 100-120
km/h (60-75 mph), approximately 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby generating electricity. This implies
that any increase in power consumption also increases fuel consumption!
For this reason, switch off any unneeded consumption of electricity. Electri-
cal equipment which uses a lot of electricity includes the blower (at a high
setting), the rear window heating and the seat heating*. 
Environmental friendliness
Environmental protection is a top priority in the design, choice of materials
and manufacture of your new SEAT.
Constructive measures to encourage recycling
● Joints and connections designed for easy dismantling
● Modular construction to facilitate dismantling
● Increased use of single-grade materials.
● Plastic parts and elastomers are marked in accordance with ISO 1043,
ISO 11469 and ISO 1629.
Choice of materials
● Use of recycled materials.
● Use of compatible plastics in the same part if its components are not
easily separated. 

234Trailer
Trailer
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 you wish to retrofit a towing bracket, consult ⇒ page 236.
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 Technical Service.
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 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. The figures for
trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for
the towing bracket, are given in the vehicle documentation or in ⇒ chap-
ter 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 mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er 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 rear vision mirrors. If this is not the case, you should have addi-
tional exterior 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. 

239
Care and cleaning
Washing the car by hand
When washing the car by hand, use plenty of water to soften the dirt first,
and rinse off as well as possible.
Then clean the vehicle with a soft sponge, glove or brush using only slight
pressure. You should start on the roof and work down. Special car shampoo
should only be used for very persistent dirt.
Rinse the sponge or glove thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second sponge for
this.
WARNING
● The vehicle should only be washed with the ignition switched off.
Failure to do so could result in an accident.
● Do not clean the underside of chassis, the inside of wheel arches or
wheel trims without protecting your hands and arms. You may cut your-
self on sharp-edged metal parts. Otherwise, there is a risk of sustaining
cuts.
● When washing the car during the winter season: water and ice in the
brake system can reduce braking effectiveness: risk of accident!
CAUTION
● Do not wash the vehicle in direct sunlight – otherwise the paint can be
damaged.
● Do not use sponges, abrasive household sponges or similar to clean in-
sect remains. This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from the headlights at regular in-
tervals, for instance when filling the fuel tank. The headlights should only
be washed with water, do not wipe them with a dry cloth or sponge. It is
best to use soapy water. ●
Never wash tyres with a jet that sprays the water out in a direct stream.
This could damage the tyres even if the spray is kept at a distance and only
used for a very short time.
● Before washing the vehicle in an automatic car wash, please make sure
to retract the exterior mirrors to prevent them from being damaged. Electri-
cally retractable exterior mirrors must not be folded in or out by hand. Al-
ways use the electrical power control.
CAUTION
● If you wash the vehicle in an automatic car wash, proceed as follows to
lock and prevent the windscreen wiper blades from being pushed up to-
wards the top of the windscreen:
–the bonnet must be closed
– switch the ignition on and off
– press the windscreen wiper lever downwards briefly towards the front
(windscreen wiper function). The windscreen wiper blades will be
locked.
For the sake of the environment
The car should only be washed in special wash bays. This prevents oily wa-
ter from getting into the public drains. In some places, washing vehicles
anywhere else may be prohibited. 
Sensors and camera lenses
● Use a small brush to remove snow and a de-icer spray to remove ice.
● Clean the sensors with a solvent-free product and a soft, dry cloth.
● Moisten the camera lens using a standard alcohol-based glass cleaning
agent and clean the lens with a dry cloth. The area in front of the active
Lane Assist* lens area is normally cleaned with the windscreen washer. 

Checking and refilling levels
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, engage the filler neck correctly. If
you 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.
Note
● The filling nozzles of all natural gas pumps might not be operated in the
same way. If you do not know, ask a qualified employee at the petrol station
to do the refuelling.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of damage to the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. Bonnet
Working on components in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
.
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place the lever in neutral; if it
has an automatic gearbox, place the selector lever in position P.
● Wait for the engine to cool down.
● Keep children away from the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● If working inside the engine compartment, remember that, even when
the ignition is switched off, the radiator fan may start up automatically,
and therefore there is a risk of injury.
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure. 

General notes
– When driving with new tyres, be especially careful during the
first 500 km (300 miles).
– 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 obstacle.
– Check from time to time if the tyres are damaged (punctures,
cuts, cracks or dents). Remove any foreign objects embedded in
the treads.
– Damaged wheels and tyres must be replaced immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they rotate in
the same direction when put back.
– When removed, the wheels or tyres should be stored in a cool,
dry and preferably dark place.
New tyres
New tyres do not give maximum grip straight away and should therefore be
“run in” by driving carefully and at moderate speeds for about the first 500
km (300 miles). This will also increase the useful life of the tyres. The tread depth of new tyres may
vary, according to the type and make of
tyre and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibration or the car pulling to one side, this may indicate that one of the
tyres is damaged. Reduce speed immediately if there is any reason to sus-
pect that damage may have occurred. Inspect the tyres for damage. If no ex-
ternal damage is visible, drive slowly and carefully to the nearest special-
ised workshop and have the car inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on single
drive tyres. Always note the direction of rotation indicated when mounting
the wheel. This guarantees optimum grip and helps to avoid aquaplaning,
excessive noise and wear.
Retrofitting Accessories
If you wish to change or fit wheels, rims or wheel trims, we recommend that
you consult with a SEAT Official Service centre for advice regarding current
techniques. 
Useful life of tyres
Correct inflation pressures and sensible driving habits will
increase the useful life of your tyres.
– Check tyre pressure at least once a month, and also prior to any
long trip. 
