2009 Seat Exeo ST gas type

Airbag system
32The main parts of the front airbag system are:•an electronic control and monitoring system (control unit),•the two front airbags (airbag with gas generator) for the driver and front
passenger,•a knee airbag* for the driver,•a warning lamp
 in the dash panel insert ⇒page 29.
The airbag system operation is monitored electronically. The airbag warning
lamp will light up for a few seconds every time the ignition is switched on
(self-diagnosis).
There is a fault in the system if the warning lamp

•does not light up when the ignition is switched on ⇒ page 29•it turns off and then lights up again after the ignition is switched on,•lights up or flashes while the car is moving.
The front airbag system will not be triggered if:•the ignition is switched off,•there is a minor frontal collision,•there is a side collision,•there is a rear-end collision,•the vehicle turns over.WARNING
•The seat belts and airbags can only provide maximum protection if the
occupants are seated correctly ⇒page 10, “Proper sitting position for
occupants”.•If a fault has occurred in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise, during a frontal collision
the system may fail to trigger, or not trigger correctly.
Operation of frontal airbags
Inflated airbags reduce the risk of head or chest injury.The airbag system is designed so that the airbags for the driver and front
passenger are triggered in a severe frontal collision.
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbags fill with a propellant gas and
deploy in front of the driver and front passenger ⇒fig. 19 . The fully deployed
airbags cushion the forward movement of the front occupants and help to
reduce the risk of injury to the head and the upper part of the body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag. After the collision, the
airbag deflates sufficiently for the front occupants to see forward.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust

been removed, unless the holes left by the loudspeakers have been
correctly closed.•Always check that the openings are closed or covered if loudspeakers
or other equipment are fitted in the interior door panels.•Any work carried out to the doors should be made in a qualified author-
ised workshop.•The seat belts and airbags can only provide maximum protection if the

immediately by a qualified workshop. Otherwise, during a side collision,
the system may fail to trigger, or not trigger correctly.
Function of side airbags
Inflated airbags can reduce the risk of head or chest injury in
many side impact collisions.In some side collisions , the side airbag is triggered on the impact side of the
vehicle ⇒fig. 24 .
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust
may develop when the airbag deploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The fully deployed airbags cushion the movement of the occupants of the
front seats and the outer rear seats and help to reduce the risk of injury to the
upper body.

42Function of curtain airbags
Fully inflated airbags reduce the risk of head or chest injury in
a side collision.During some side collisions the curtain airbag is triggered on the impact side
of the vehicle ⇒fig. 26 .
In certain types of accident the front, side and curtain airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas. In the
process, the curtain bag covers the side windows and door pillars.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust
may develop when the airbag deploys. This is normal and it is not an indica-
tion of fire in the vehicle.

help to reduce the risk of injury to the upper body. The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag.
Safety notes on the operation of the curtain airbag system
If you use airbags correctly, they can considerably reduce the
risk of injury in many kinds of accident.
WARNING
•In order for the side airbags to provide their maximum protection, the
prescribed sitting position must always be maintained with seat belts
fastened while travelling.•For safety reasons, the head air bag must be disconnected in those
vehicles fitted with a passenger compartment separation screen. See an
Authorised Service Centre to make this adjustment.•There must be no other persons, animals or objects between the occu-
pants of the outer seats and the deployment space of the curtain airbags
so that the curtain airbag can deploy without restriction and provide the
greatest possible protection. Therefore, sun blinds which have not been
expressly approved for use in your vehicle may not be attached to the side
windows ⇒page 220, “Accessories, replacement of parts and modifica-
tions”.•The built-in coat hooks should be us ed only for lightweight clothing. Do
not leave any heavy or sharp-edged objects in the pockets. Please, do not
hang the clothes on coat hangers.•The airbags provide protection for just one accident; replace them once
they have deployed.•Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lining)

Driving and the environment
198Periodic 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 maximum
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 regularise until having
driven some four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up 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: they will 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 unnec-
essary loads are being transported.
A roof carrier 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 car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use. Saving electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.•Fuel consumption of a vehicle using biodiesel may be slightly higher.•RME fuel is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel, in accordance with the DIN 51628 standard.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you refuel with biodiesel, please be sure that it conforms to the
DIN E 14.214 standard.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.•The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using summer-grade diesel fuel, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation.
Therefore, winter-grade diesel fuel is available in some countries during the
cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.
