32Airbag system
Warning lamp for airbag and seat belt tensioner 
This warning lamp monitors the airbag and seat belt ten-
sioner system.
The warning lamp monitors all airbags and seat belt tensioners in the vehi-
cle, including control units and wiring connections.
Monitoring of airbag and belt tensioner system
Both the airbag and belt tensioner systems operation is constantly moni-
tored electronically. Each time the ignition is switched on, the warning lamp
 lights for several seconds and the display in the instrument panel*
shows AIRBAG / TENSIONER .
The system must be checked when the warning lamp  :
● does not light up when the ignition is switched on,
● after the ignition is switched on, it turns off after 4 seconds,
● turns off and then lights up again after the ignition is switched on,
● lights up or flashes while the vehicle is moving.
In the event of a malfunction, the warning lamp remains on continuously. In
addition, depending on the malfunction, a fault message appears in the
display of the instrument panel for approx. 10 seconds and a short acoustic
signal is given. In this event, you should have a specialised workshop check
the system immediately.
If any of the airbags are de-activated by the Authorised Service Centre, the
indicator lights for several seconds more after the verification and will turn
off if there is no fault.WARNING
● If there is a malfunction, the airbag and belt tensioner system cannot
properly perform its protective function.
● If a malfunction occurred, have the system checked immediately by a
specialised workshop. Otherwise, in the event of an accident, the airbag
system and belt tensioners may not be triggered, or may not be triggered
correctly.

Repairs, maintenance and disposal of airbags
The parts of the airbag system are installed in various places in your vehi-
cle. If work is carried out on the airbag system or parts have to be removed
and fitted on the system when performing other repair work, parts of the air-
bag system may be damaged. In the event of an accident this could cause
the airbag to inflate incorrectly or not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are scrapped. Specialised workshops and vehicle
disposal centres are familiar with these requirements.
WARNING
● If repairs are not carried out by a professional, or if the airbags are
used incorrectly, the risk of severe or fatal injuries is increased. The air-
bags may fail to inflate, or could inflate in the wrong circumstances.
● Do not cover or stick anything on the steering wheel hub or the sur-
face of the airbag unit on the passenger side of the dash panel, and do
not obstruct or modify them in any way.
● It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units. 

62Cockpit
Recommended gear display*
This display helps to save fuel.
Fig. 38 Gear display
Use the gear display to save fuel. If you are driving in the correct gear, a dot
will be shown next to the gear display. If you are not in the correct gear, an
arrow will appear next to the gear display indicating whether you should
change up or down.
Note
The gear change indication should not be taken into account the accelera-
tion is required (for example when overtaking). 
Odometer or flexible service interval display
Odometer
The left-hand counter in the display registers the total amount of distance
covered by the vehicle. The right-hand counter registers the short journeys. The last digit indicates
steps of 100 metres. The trip recorder counter may be reset by holding
down the reset button for a few seconds.
Service interval display
Vehicles with
Service intervals dependent on time/distance travelled al-
ready have certain service intervals set. The intervals are calculated individ-
ually in vehicles with LongLife service.
The service interval display only indicates the dates of services that include
engine oil change. The dates of all other services, such as Inspection Serv-
ice or brake fluid change, appear in the sticker on the door pillar or in the
Maintenance Programme.
A Service pre-warning will appear in the odometer if a service is due soon. A
“spanner” symbol appears and the display “km” with the distance that can
be driven until the next service appointment is due. The display will change
after approximately 10 seconds. A “clock symbol” appears and the number
of days until the service appointment should be carried out. The following
message is shown in the instrument panel display*: Service in
[XXXX]
kmor
[XXXX]
days
The service message will disappear approximately 20 seconds after the ig-
nition is switched on or the engine is running. The normal display can be
resumed by briefly pressing the reset button on the trip counter or by press-
ing the OK
button on the steering wheel controls.
With the ignition on, you can check the current service message at any mo-
ment in the Vehicle status menu or turning the reset button to access the
service display.
An overdue service is indicated by a minus sign in front of the mileage or
day information. 

Driving and the environment
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.
Fig. 136 Vehicle data
sticker on back cover of
the Maintenance Pro-
gramme
Your vehicle is fitted with a DPF (Diesel particulate filter) if the vehicle data
sticker (back cover of the “Maintenance Programme”) lists the PR code 7GG
or 7MG ⇒ fig. 136.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
indicator  for the diesel engine particulate filter indicator will light up.
This does not represent a fault, it is a warning that indicates that the filter
has not been able to regenerate automatically and that you must carry out a
cleaning cycle, as indicated in ⇒ page 83.
WARNING
● The diesel engine particulate filter may reach extremely high temper-
atures; the vehicle should be parked so that the exhaust pipe does not
come into contact with flammable materials underneath the vehicle. Oth-
erwise there is a risk of fire.
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur content may significantly reduce
the working life of the diesel particulate filter. Your Authorised Service Cen-
tre will be able to tell you which countries have diesel with a high sulphur
content. 
Economical and environmentally friendly
driving
Economical and environmentally friendly driving
Fuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an eco-
nomical driving style and anticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%. Some tips on how to help you
reduce pollution while saving money are listed below. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

192Driving and the environment
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 62.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
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.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced engine gives you the benefit of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no un-
necessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof
rack even when it is not in use. 

194Driving and the environment
Driving abroad
Observations
To drive abroad, the following must be taken into consideration:
● For vehicles fitted with a catalytic converter ensure that unleaded petrol
is available for the journey. See the chapter “Refuelling”. Automobile organ-
isations will have information about service station networks selling unlea-
ded fuel.
● In some countries, it is possible that your vehicle model is not sold, and
therefore spare parts are not available or the Authorised Services can only
carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparations that you vehicle requires and also about necessary
maintenance and repair possibilities. 
Adhesive strips for headlights
If you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the head-
light lenses. Further information is available at your Authorised Service Cen-
tre.
In vehicles with adaptive headlights, the rotation system must previously be
disconnected. To do this, please go to a specialised workshop. 
