in the direction of the collision. The belt ten-
sioner works in combination with the airbag
system. The belt tensioner will not be trig-
gered in the event of the vehicle overturning
if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is
produced. This is normal and it is not an indi-
cation of fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the force of
the seat belt on the body in the event of an
accident. Note
The relevant safety requirements must be ob-
served when the vehicle is dismantled or sys-
tem components are removed. These require-
ments are known to specialised workshops
››› page 17. Service and disposal of belt
tensioners
If you work on the belt tensioners or remove
and install other parts of the vehicle when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or not at all. So that the effectiveness of the belt tensioner
is not reduced and that removed parts do not
cause any injuries or environmental pollu-
tion, regulations must be observed. These re-
quirements are known to specialised work-
shops.
WARNING
Improper handling and homemade repairs of
seat belts, automatic belt retainers and ten-
sion devices increase the risk of sustaining
severe or fatal injuries. The belt tensioner
may fail to trigger or may trigger in the wrong
circumstances.
● Never attempt to repair, adjust or remove or
install parts of the belt tensioners or seat
belts. Any work must be performed by a spe-
cialised workshop only ››› page 118.
● Belt tensioners and automatic belt retain-
ers cannot be repaired and must be replaced. For the sake of the environment
Airbag modules and belt tensioners may con-
tain perchlorate. Observe the legal require-
ments for their disposal. Airbag system
Brief introduction Introduction Front airbags have been installed for both
driver and passenger. The front airbags can
also protect the chest and head of driver and
passenger if the seats, seat belts head re-
straints and, for the driver, the steering
wheel are correctly adjusted and used. Air-
bags are considered as additional safety
equipment. An airbag cannot replace the
seat belt, which must be worn at all times,
even in front seats where front airbags have
been installed.
The airbag can protect vehicle occupants in
the event of an accidents, cushioning the
movement of the occupants in the direction
of the collision in frontal and side accidents.
Deployed airbags fill with a propellant gas.
This causes the airbag covers to break and
the airbags to deploy extremely quickly in
their entire deployment space within frac-
tions of a second. When an occupant with the
seat belt properly fastened puts pressure on
the inflated airbag, the propellant gas es-
capes to absorb the force of the impact and
slow the movement. This reduces the risk of
severe or fatal injuries. Airbag deployment
does not mean that other types of injury such

Driving
The vehicle uses more fuel in winter than in
summer, even when other conditions are the
same.
“Warming” the engine is not only forbidden
in some countries, but in practice it is techni-
cally superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals).
When purchasing engine oil, always observe
legal requirements and ensure that the oil is
approved by SEAT. Avoid carrying unnecessary loads
The lighter the vehicle, the more economical
and ecological the driving style. For example,
an additional weight of 100 kg will increase
fuel consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and
unnecessary accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel
consumption (examples):
●
Fault in engine management.
● Driving on hills. WARNING
Always adapt your speed and the distance to
the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation. Engine management and

Introduction WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass).
● Never apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. Control lampsIt lights

metal additives. Using them may damage the
engine!
● Only use fuel with an octane rating that is
in line with the norm EN 228, otherwise sig-
nificant damage could be caused to the en-
gine and fuel system. Furthermore, it could
lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could
seriously damage the engine and the catalyt-
ic converter.
● If, in exceptional circumstances, petrol with
a lower octane rating to that recommended is
used, only use moderate engine speeds and a
light throttle. Avoid using full throttle and
overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suita-
ble octane rating as soon as possible.
● Just filling one full tank of leaded fuel or
with other metal additives would seriously
impair the efficiency of the catalytic convert-
er and could damage it. Natural gas
Natural gas, in addition to others, can be in
liquid form.
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas
››› .
Natural gas quality and consumption
Natural gas is divided into the groups H and
L depending on its quality.
Gas type H has a superior heating power and
inferior nitrogen and carbon dioxide content
than type L. The higher the heating power of
the natural gas, the lower the consumption
will be.
However, the heating power and the propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
one type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need
for comprehensive draining before applying a
different quality gas.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately. ●
Switch the ignition off.
● Open the doors to appropriately ventilate
the vehicle.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. 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 natural gas system must be subject to
regular inspections at a specialised work-
shop in accordance with the Maintenance
Programme. 138

This only applies to vehicles with the fuel gauge on the dash panel display.
Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
In natural gas engines
The warning lamp  lights up when both fuel
type

s (petrol and natural gas) have reached

The warning lamp  lights up when the vehi-
cl

e is running in natural gas operating mode.
The warning lamp  switches off when the
natural gas is exhausted. The engine
changes to operate with petrol.
Problem:
if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does 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 pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

● If the aut

omatic filler nozzle is operated
correctly, it will switch itself off as soon as
the fuel tank is full ››› .
● Do not continue to refuel if it is turned off!
Otherwise, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Closing the fuel tank cap
● Screw on the fuel tank filler plug in a clock-
wise direction until it is fully inserted with a
click.
● Insert the vehicle key into the lock cylinder

● Close the tank flap. Make sure you hear it
click into place. WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can 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 natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. ●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet
