Sitting position for vehicle occupants
Introduction
WARNING
● The front seats, head restraints and seat belts must always be adjus-
ted to the size of the vehicle occupant to provide you and your passen-
gers with the greatest possible protection.
● Ensure your correct sitting position before setting off, and do not
change this during the journey. Also advise your passengers to ensure
their correct sitting positions not to be changed.
● A vehicle occupant sitting in an incorrect position is at risk of serious
injury in the event that an airbag is activated.
● If the passengers in the rear seats are not sitting in an upright posi-
tion, they are more likely to be injured due to the incorrect position of the
seat belts.
● It is important that the driver keeps at a minimum of 25 cm from the
steering wheel. It is important that the passenger keeps at a minimum of
25 cm from the dash panel. The airbag system will not be able to give the
required protection if the minimum distance is not observed. This can
cause a risk of fatal injury!
● When driving, always hold the steering wheel with both hands on the
outside part at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel or along its interior edge). In such cases,
if the airbag is triggered, you may sustain injuries to the arms, hands
and head.
● The backrests must not be reclined too far back while driving. This
could limit the effect of the seat belts and the airbag system. Risk of in-
jury!
WARNING (Continued)
● Objects must not be placed in the footwell, as they could move to the
area of the pedals in the event of a braking manoeuvre or change of direc-
tion. This would prevent the clutch, brake or accelerator from being
pressed.
● Always keep your feet on the footwell when the vehicle is moving;
never rest them on the dash panel, on the window or on the seat! An in-
correct sitting position exposes you to an increased risk of injury in case
of a sudden braking or an accident. If the airbag is triggered, you could
sustain severe injuries due to an incorrect sitting position!

12Safe driving
WARNING
● An incorrect sitting position of the driver can lead to severe injuries.
● Adjust the driver seat so that there is at least 25 cm distance between
the centre of the chest and the centre of the steering wheel ⇒ Fig. 1. If
you are sitting closer than 25 cm, the airbag system cannot protect you
properly.
● If your physical constitution prevents you from maintaining the mini-
mum distance of 25 cm, contact a specialised workshop. The workshop
will help you decide if special specific modifications are necessary.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. This reduces
the risk of injury when the driver airbag is triggered.
● Never hold the steering wheel at the 12 o'clock position, or in any
other manner (e.g. in the centre of the steering wheel). In such cases, if
the airbag is triggered, you may sustain injuries to the arms, hands and
head.
● To reduce the risk of injury to the driver during sudden braking ma-
noeuvres or an accident, never drive with the backrest tilted far back! The
airbag system and seat belts can only provide optimal protection when
the backrest is in an upright position and the driver is wearing his or her
seat belt correctly. The further the seat backrests are tilted to the rear,
the greater the risk of injury due to incorrect positioning of the belt web
or to the incorrect sitting position!
● Adjust the head restraint properly to achieve optimal protection.
 Correct sitting position for front passenger
The front passenger must sit at least 25 cm away from the
dash panel so that the airbag can provide the greatest pos-
sible protection in the event that it is triggered.
For your own safety and to reduce the risk of injury in the event of
an accident, we recommend the following adjustments for the front
passenger:
– Move the front passenger seat back as far as possible ⇒ 
.
– Move the seat backrest to an upright position so that your back
rests completely against it.
– Adjust the head restraint so that its upper edge is at the same
level as the top of your head, or as close as possible to the
same level as the top of your head ⇒ page 14.
– Always keep both feet in the footwell in front of the front pas-
senger seat.
– Fasten your seat belt securely ⇒ page 19.
It is possible to deactivate the front passenger airbag in exceptional circum-
stances ⇒ page 26.

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. 

Diesel Fuel
Please note the information on the inside of the fuel tank
flap.
We recommend the use of Diesel fuel which complies to European standard
EN 590. If diesel fuel which meets European standard EN 590 is not availa-
ble, the Cetane number (CZ) must, at minimum, be 51. If the engine is
equipped with a particulate filter, the sulphur content of the fuel must be
below 50 parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it is more difficult to start the
engine. For this reason petrol stations in some countries also offer winter
diesel with improved fluidity when cold.
CAUTION
● The vehicle is not designed for the use of biodiesel (FAME fuel). The fuel
system would be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called “thinners”, petrol or similar ad-
ditives with diesel fuel.
● If poor-quality diesel fuel is used, it may be necessary to drain the fuel
filter more frequently than is specified in the Service Plan. We recommend
having this done by a specialised workshop. If water is allowed to collect in
the filter, this can cause engine performance problems. Filling the tank

If the vehicle is not used for long periods
The vehicle has a system for monitoring the current consumption when the
engine is left unused for long periods of time ⇒ page 187. Some functions,
such as the interior lights, or the remote door opening, may be temporarily
disabled to prevent the battery from running flat. These functions will come
back on as soon as the ignition is switched on and the engine started.
Winter conditions
During the winter, the starting power may be reduced, and if necessary, the
battery should be charged ⇒ 
in Important safety warnings for handling a
vehicle battery on page 218 
Important safety warnings for handling a vehicle battery
All work on batteries requires specialist knowledge. Please refer to a SEAT
Official Service or a workshop specialising in batteries: risk of burns or ex-
ploding battery!
The battery must not be opened. Never try to change the fluid level of the
battery. Explosive gas is released from the battery that could cause an ex-
plosion.
Wear eye protection.
Battery acid is very corrosive and caustic. Wear protective gloves
and eye protection. In the event of electrolyte splashes, rinse off
with plenty of water.
Fires, sparks, open flames and smoking are prohibited.
The battery should only be charged in a well-ventilated zone. Risk
of explosion!
Keep children away from acid and batteries!
WARNING
● When repairing or working on the electrical system, proceed as fol-
lows:
● 1. Remove the key from the ignition. The negative cable on the bat-
tery must be disconnected.
● 2. When the repair is finished, reconnect the negative pole of the bat-
tery.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Ensure that the vent hose is always connected to the battery.
● Never use damaged batteries. This could cause an explosion! Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents. 
