8Safe driving
passengers are sitting in a correct position and use this equipment proper-
ly.
Therefore, information is provided about why this equipment is so impor-
tant, how it protects you, what you have to consider when using it and how
you and your passengers can achieve the greatest possible benefit from the
safety equipment fitted. This manual includes important warnings that you
and your passengers should note in order to reduce the risk of injury.
Safety is everyone's business! 
Before starting every trip
The driver is always responsible for the safety of the passen-
gers and the safe operation of the vehicle.
For your own safety and the safety of your passengers, always note
the following points before every trip:
– Make sure that the vehicle's lights and turn signals are working
properly.
– Check tyre pressure.
– Ensure that all windows provide a clear and good view of the
surroundings.
– Make sure all luggage is secured ⇒ page 17.
– Make sure that no objects can interfere with the pedals.
– Adjust front seat, head restraint and rear vision mirrors properly
according to your size. –
Ensure that the passengers in the rear seats always have the
head restraints in the in-use position ⇒ page 15
– Instruct passengers to adjust the head restraints according to
their height.
– Protect children with appropriate child seats and properly ap-
plied seat belts ⇒ page 47.
– Assume the correct sitting position. Instruct your passengers al-
so to assume a proper sitting position. ⇒ page 10.
– Fasten your seat belt securely. Instruct your passengers also to
fasten their seat belts properly. ⇒ page 19. 
What affects driving safety?
Driving safety is largely determined by your driving style
and the personal behaviour of all vehicle occupants.
As a driver, you are responsible for yourself and your passengers.
When your concentration or driving safety is affected by any cir-
cumstance, you endanger yourself as well as others on the road
⇒ 
, for this reason:
– Always pay attention to traffic and do not get distracted by pas-
sengers or telephone calls.
– Never drive when your driving ability is impaired (e.g. by medi-
cation, alcohol, drugs).
– Observe traffic laws and speed limits. 

20Seat belts
After the ignition has been switched on, the control lamp  on the instru-
ment panel lights up 1)
if the driver has not fastened his/her seat belt, and
an audible warning is heard if the vehicle is driven at more than 30 km/h
(20 mph).
The warning lamp*  is switched off if the driver seat belt is fastened while
the ignition is switched on. 

Deactivating airbags
Deactivating airbags
The deactivation of airbags corresponds only to certain cases, i.e. if:
● a child seat is required in the front passenger seat with the child facing
in the opposite direction to the direction of travel (in some countries, due to
divergent legal requirements, facing in the direction of travel) ⇒ page 49;
● despite the driver seat being in the correct position, a minimum dis-
tance of 25 cm cannot be maintained between the centre of the steering
wheel and the driver's torso.
● installation of special devices is required in the steering wheel area due
to a physical disability.
● if you have special seats installed (e.g. an orthopaedic seat without side
airbag).
The front passenger front airbag can be disabled using the switch
⇒ page 45.
We recommend that you contact an authorised SEAT dealer for the disabling
of other airbags.
Airbag system control
The airbag system availability is controlled electronically, regardless of
whether an airbag is disabled.
If an airbag was disabled using a diagnostics system:
● the airbag system warning lamp  lights up after switching on the igni-
tion for about 4 seconds, and then flashes for about 12 seconds If the airbag has been disabled with the airbag switch on the side of the
dash panel:
●
the airbag control lamp  will light up for about 4 seconds after the ig-
nition is switched on.
● The airbag is disabled, signalled with the warning lamp   which
lights up with the word      placed in the centre part of the
dash panel ⇒ Fig. 26.
Note
● Respect the current legislation in your country regarding the deactiva-
tion of airbags
● At your authorised SEAT dealer you can find information on which vehi-
cle airbags can be deactivated. 

el: Odometer and reset
button
The distance covered is displayed in “kilometres” or miles “m”. It is possi-
ble to change the measurement units (kilometres “km”/miles “m”) in the
radio/Easy Connect*. Please refer to the Easy Connect* Instruction Manual
for more details.
Odometer/trip recorder
The odometer shows the total distance covered by the vehicle.
The trip recorder shows the distance that has been travelled since it was
last reset. It is used to measure short trips. The last digit of the trip recorder
indicates distances of 100 metres or one tenths of a mile.
The trip recorder can be set to zero by pressing 0.0/SET

⇒  Fig. 38.
Fault display
If there is a fault in the instrument panel, the letters DEF will appear in the
trip recorder display. Have the fault repaired immediately, as far as is possi-
ble. Fuel level
The display
6 ⇒ Fig. 36 only works when the ignition is switched on. When
the display reaches the reserve mark, the lower diode lights up in red and
the control lamp  appears ⇒ page 207. When the fuel level is very low,
the lower diode flashes in red.
The distance to empty fuel level is displayed on the instrument panel 3
⇒ Fig. 36.
The capacity of the fuel tank of your vehicle is given in the Technical data
section ⇒ page 276.
CAUTION
Never run the fuel tank completely dry. An irregular fuel supply could cause
misfiring. In this way the fuel can arrive without burning the exhaust sys-
tem, which could cause the catalytic converter to overheat resulting in dam-
age. 
Coolant temperature gauge
For vehicles with no coolant temperature gauge, a control lamp appears for
high coolant temperatures  ⇒ page 215. Take into account the ⇒ .
The coolant temperature gauge 2
⇒ Fig. 36 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Engine cold
If only the diodes in the lower part of the scale light up, this indicates that
the engine has not yet reached operating temperature. Avoid high revs and
heavy acceleration and do not make the engine work hard. 
