CAUTION
The gear-change indicator is intended to help save fuel. It is not intended to
recommend the right gear for all driving situations. In certain situations, on-
ly the driver can choose the correct gear (for instance when overtaking, driv-
ing up a steep gradient or towing a trailer).
Note
The display disappears from the instrument panel when you press the
clutch pedal. 
Control lamps Control and warning lamps
The control and warning lamps are indicators of warnings, ⇒ , faults ⇒ or certain functions. Some control and warning lamps come on when the ig-
nition is switched on, and switch off when the engine starts running, or
while driving.
Depending on the model, additional text messages may be viewed on the
instrument panel display. These may be purely informative or they may be
advising of the need for action ⇒ page 61, Instruments. Depending upon the equipment fitted in the vehicle, instead of a warning
lamp, sometimes a symbol may be displayed on the instrument panel.
When certain control and warning lamps are lit, an audible warning is also
heard.

Seats and storage
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.
● Do not leave clothing that is wet or damp on the seat.
● Do not spill liquid on the seat.
CAUTION
● To avoid damaging the heating elements of the seat heating, please do
not kneel on the seat or apply sharp pressure at a single point to the seat
cushion and backrest.
● Liquids, sharps objects and insulating materials (e.g., covers or child
seats) can damage the seat heating.
● In the event of odours, switch off the seat heating immediately and have
the unit inspected by a specialised workshop.
For the sake of the environment
The seat heating should remain on only when needed. Otherwise, it is an
unnecessary fuel waste. Head restraints

Tyre monitoring systems Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Caring for and cleaning the vehicle exterior ⇒ page 198
● Wheels and tyres ⇒ page 223
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre
pressure losses, to tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. Tyre pressure that is too low could cause overheat-
ing, resulting in tread detachment or even burst tyres.
● Tyre pressure should be that indicated on the label when the tyres are
cold at all times ⇒ page 266.
● Regularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
● Regularly check your tyres for damage and wear.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
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. 

192Driving 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 off after about 5 seconds al-
ready 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 223 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 production of your new SEAT.
Design measures for economical recycling
● Joints and connections designed for easy dismantling
● Modular construction to facilitate dismantling
● Increased use of single-grade materials
● Plastic parts and elastomers are rated in accordance with ISO 1043, ISO
11469 and ISO 1629
Choice of materials
● Nearly all materials used can be recycled
● Use of suitable plastics within the same system/set
● Recycled materials used in manufacture 

194Trailer
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 196.
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. 

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.
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.
CAUTION
● When you clean the vehicle with a pressure washer,
– stay a suitable distance from the sensors on the front and rear bump-
ers.
– Do not clean the camera lenses or surrounding area with the pressure
washer.
● Never use warm or hot water to remove snow and ice from the reverse
camera lens, as it could crack the lens.
● Never use abrasive cleaning agents on the lens. 

Checking and refilling levels
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 

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.
WARNING (Continued)
● 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.
● Protect face, hands and arms by covering the cap with a large, thick
rag to protect against escaping coolant and steam.
● If it is necessary to work in the engine compartment while the engine
is running, the rotating components (for example, poly-V belt, alternator,
radiator fan) and the high voltage ignition system are an additional haz-
ard.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary:
–Always disconnect the battery from the on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguisher immediately available. 
