34Airbag system
WARNING
In the event of a fault in the airbag system, the airbag may not trigger
correctly, may fail to trigger or may even trigger unexpectedly, leading to
severe or fatal injuries.
● Have the airbag system checked immediately by a specialised work-
shop.
● Never mount a child seat in the front passenger seat or remove the
mounted child seat! The front passenger front airbag may deploy during
an accident in spite of the fault.
CAUTION
Always pay attention to any lit control lamps and to the corresponding de-
scriptions and instructions to avoid damage to the vehicle. 
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.
● To clean the steering wheel or dash panel, you may use only a dry or a
water-moistened cloth. Never clean the dash panel and the airbag mod-
ule surface with cleaners containing solvents. Solvents cause the surface
to become porous. If the airbag triggered, plastic parts could become de-
tached and cause injuries.
● Never attempt to repair, adjust, remove or install parts of the airbag
system.
● Any work on the airbag system or removal and installation of the air-
bag components for other repairs (such as repairs to the steering wheel)
should be performed only by a specialised workshop. Specialised work-
shops have the necessary tools, repair information and qualified person-
nel.
● We strongly recommend you to go to a specialised workshop for all
work on the airbag system.
● Never attempt to alter the front bumper or the body.
● The airbags provide protection for just one accident; replace them
once they have deployed.
For the sake of the environment
The airbags, which are a special type of waste, must be disposed of through
an authorised service, because they contain pyrotechnic elements. 

Instruments and warning/control lamps
WARNING
Although the outside temperature is above freezing, some roads and
bridges may be frozen.
● At an outside temperature of above +4 °C (+39 °F), even when the
“ice crystal” is not visible, there may still be ice on the road.
● Never rely on the outside temperature indicator!
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.
Note
● Different versions of the instrument panel are available and therefore
the versions and instructions on the display may vary. In the case of dis-
plays without warning or information texts, faults are indicated exclusively
by the warning lamps.
● Depending on the equipment, some settings and instructions can also
be carried out in the Easy Connect system.
● When several warnings are active at the same time, the symbols are
shown successively for a few seconds. The symbols will stay on until the
fault is rectified. 
Service interval display
The inspection message appears on the instrument panel display
⇒ Fig. 36 4.
SEAT makes a difference between services with engine oil change (Interval
Service) and services without engine oil change (Inspection Service). The
service interval display only gives information for service dates which in-
volve an engine oil change. The dates of the remaining services (for exam- ple, the next Inspection Service or change of brake fluid) are listed on the
label attached to the door strut, or even in the Maintenance Programme.
In vehicles with
Services established by time or mileage , the service inter-
vals are already pre-defined.
In vehicles with LongLife Service , the intervals are determined individually.
Technical progress has made it possible to considerably reduce servicing re-
quirements. The technology used by SEAT ensures that your vehicle only
has an Interval Service when it is necessary. To establish when the Interval
Service is due (max. 2 years), the vehicle's conditions of use and individual
driving styles are considered. The service pre-warning first appears 20 days
before the date established for the corresponding service. The kilometres
remaining until the next service are always rounded up to the nearest 100
km (miles) and the remaining time is given in complete days. The current
service message cannot be viewed until 500 km (miles) after the last serv-
ice. Prior to this only lines are visible on the display.
Inspection reminder
When the Service date is approaching, when the ignition is switched on a
Service reminder is displayed.
In vehicles without text messages , a spanner is displayed on the instrument
panel  with a figure given in km. The number of kilometres shown is the
maximum number that may be driven until the next service. After a few sec-
onds, the display mode changes. A clock symbol appears and the number
of days until the next service appointment is due.
In vehicles with text messages , Service in --- km (miles) or --- days is dis-
played on the instrument panel.
Service due
After the service date, an audible warning is given when the ignition is
switched on and the spanner displayed on the screen flashes for a few sec-
onds . In vehicles with text messages , Service in --- km or --- days is dis-
played on the instrument panel. 

Reading a service notification
With the ignition switched on, the engine off and the vehicle at a standstill,
the current service notification can be read:
Press and hold the button ⇒ Fig. 36 4
for more than 5 seconds to consult
the service message.
When the service date has past , a minus sign is displayed in front of the
number of kilometres or days. In vehicles with text messages the following
is displayed: Service --- km (miles) or --- days ago .
The time can also be set via the 
key and Setup function button in the
Easy Connect system ⇒ page 79.
The service interval display is reset
If the service was not carried out by a SEAT dealership, the display can be
reset as follows:
● To reset the service interval display, turn the ignition off and press and
hold the button ⇒ Fig. 36 4
.
● Switch the ignition back on.
● Release the button 4
and press the button 4 again for the next 20
seconds.
Note
● The service message disappears after a few seconds, when the engine is
started or when OK/RESET
is pressed on the windscreen wiper lever, or OKon the multifunction steering wheel.
●
In vehicles with the LongLife system in which the battery has been dis-
connected for a long period of time, it is not possible to calculate the date
of the next service. Therefore the service interval display may not be correct.
In this case, please check the maximum permitted service intervals ⇒ Book-
let Maintenance Programme. Rev counter
The rev counter indicates the number of engine revolutions
per minute.
Together with the gear-change indicator, the rev counter offers you the pos-
sibility of using the engine of your vehicle at a suitable speed.
The start of the red zone on the dial indicates the maximum engine speed
which may be used briefly when the engine is warm and after it has been
run in properly. Before reaching this range, you should change to a higher
gear for vehicles with a manual gearbox or for automatic gearboxes put the
selector lever in “D” or take your foot off the accelerator pedal.
We recommend that you avoid high revs and that you follow the recommen-
dations on the gear-change indicator. Consult the additional information in
⇒  page 68, Gear-change indicator.
CAUTION
Never allow the rev counter needle 1 ⇒ Fig. 36 to go into the red zone on
the scale for more than a very brief period, otherwise, there is a risk of en-
gine damage.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise engine
noise. 

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*. 

● Recycled materials used in manufacture 

204Care and cleaning
More stubborn dirt
–More stubborn dirt can be removed using a mild soap solution
(pure liquid soap: two tablespoons dissolved in one litre of wa-
ter).
– Do not let the water soak through the leather or penetrate into
the seams.
– Then wipe off with a soft, dry cloth.
Removal of stains
– Remove fresh water-based stains such as coffee, tea, juices,
blood etc. with an absorbent cloth or kitchen roll, dried-on
stains with the cleaning agent from the care set.
– Remove fresh fat-based stains that have not penetrated the sur-
face such as butter, mayonnaise, chocolate, etc. with an ab-
sorbent cloth or kitchen roll or with the cleaning agent from the
care set.
– Treat fat-based, dried-in stains with grease-dissolving spray.
– Treat less common stains such as ball-pen and other inks, felt-
tip pens, nail polish, dispersion paint, shoe cream etc. with a
special leather stain remover.
Leather maintenance
– The leather should be treated regularly (about twice a year) with
a special leather-care product.
– Apply these products very sparingly.
– Then wipe off with a soft, dry cloth. Should you have questions regarding the care and cleaning of the leather
upholstery in your vehicle, we recommend that you contact your SEAT Offi-
cial Service. Our representatives will be happy to advise you and tell you
about the product range for leather conservation, for example:
●
Cleaning and care set
● Coloured leather-care cream
● Stain remover for ball-pen inks, shoe cream etc.
● Grease dissolving spray
● New products and further developments
CAUTION
On no account use solvents (such as petrol, turpentine), wax polish, shoe
cream or similar materials. 
Cleaning Alcantara upholstery
Removing dust and dirt
– Moisten a cloth just a little and wipe down the seat covers.
Removing stains
– Moisten a cloth with lukewarm water or diluted white spirits.
– Dab at the stain. Start at the outside and work inwards.
– Dry the area you have cleaned with a soft cloth.
Do not use leather cleaning products on Alcantara seat covers.
You may use a suitable shampoo on dust and dirt.
Dust and grit in the pores and seams can scratch and damage the surface. If
the car is left standing in the sun for long periods, Alcantara leather should 

Checking and refilling levels
WARNING
● For safety reasons the bonnet must always be completely closed
when the vehicle is moving. Therefore, after closing the bonnet, always
check that the locking element is properly engaged. This is the case if
the bonnet is flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.

Engine oil General notes
The engine comes with a special, multi-grade oil that can be used all year
round.
Because the use of high-quality oil is essential for the correct operation of
the engine and its long useful life, when topping up or changing oil, use on-
ly those oils that comply with VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines.
We recommend that the oil change, indicated in the Maintenance Pro-
gramme, be performed by a Technical Service or a specialised workshop.
The correct oil specifications for your engine are listed in ⇒ page 212, Oil
properties. Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the “Maintenance Programme”
booklet is PR QI6, this means that your vehicle has the LongLife service pro-
grammed. If it lists the codes QI1, QI2, QI3, QI4 or QI7, the interval service
is dependent on time/distance travelled.
Flexible service intervals (LongLife service intervals*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, enable the extension of the
oil change service (LongLife service intervals).
Because this oil is essential for extending the service intervals, it
must only
be used observing the following indications:
● Avoid mixing it with oil for fixed service intervals.
● Only in exceptional circumstances, if the engine oil level is too low
⇒ page 212 and LongLife oil is not available, it is permitted to top up
(once) with oil for fixed service intervals ⇒  page 212 (up to a maximum of
0.5 litres).
Fixed service intervals*
If your vehicle does not have the “LongLife service interval” or it has been
disabled (by request), you may use oils for fixed service intervals, which al-
so appear in ⇒ page 212, Oil properties. In this case, your vehicle must be
serviced after a fixed interval of 1 year/15 000 km (10 000 miles)(whatever
comes first) ⇒ Booklet Maintenance Programme.
● In exceptional circumstances, if the engine oil level is too low
⇒ page 212 and you cannot obtain the oil specified for your vehicle, you
can put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5
l). 
Safety FirstOperating instructionsPractical TipsTechnical specifications

212Checking and refilling levels
Vehicles with diesel particulate filter*
The “Maintenance Programme” states whether your vehicle is fitted with a
diesel particulate filter.
Only VW 507 00 engine oil, with reduced ash formation, may be used in die-
sel engines equipped with particulate filter. Using other types of oil will
cause a higher soot concentration and reduce the life of the DPF. Therefore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the engine oil level is too low
⇒  page 212 and you cannot obtain the oil specified for your vehicle, you
can use a small quantity of oil (once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or ACEA B3/ACEA B4 specification. (up
to 0.5 l). 

Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and recommend keeping it in the vehicle.
This way, the correct engine oil will always be available for a top-up if nee-
ded. 
