After the engine is switched off the radiator

the ignition is switched off. It is also possi-
ble that the fan turns itself on once more if
the coolant temperature increases due to
the heat accumulated in the engine com-
partment or due to its prolonged exposure
to solar radiation. Electronic immobilizer
The electronic immobiliser prevents unau-
thorised persons fr
om driving the v
ehicle
.
Inside the k

ey there is a chip that deactivates
the electronic immobiliser automatically
when the key is inserted into the ignition.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock. For vehicles with
the “Keyless Access” system, the key has to
be outside the vehicle.
If the following message is shown on the in-
strument panel display: SAFE , the vehicle
cannot be started.
The engine can only be started using a genu-
ine SEAT key with its correct code. Note
A perfect operation of the vehicle is ensur-
ed if genuine SEAT keys are used. Emergency starting function

CAUTION
When travelling at high speeds or at high
engine speeds, selecting a gear that is too
lo w can cause consider
able damage to the
clutch and the gearbox. This can also oc-
cur if the clutch pedal is pressed and held
and it does not engage. CAUTION
To prevent damage and avoid premature
wear, please observ e the f

ollowing:

ment panel display.
Do not continue driving if the steering column re-
mains locked after switching on the ignition. Seek
specialist assistance. The control lamp should light up for a few
seconds when the ignition is s

Never ignore the warning lamps or messag-

Start and driving
For the sake of the environment
If the engine is run in gently, the life of the
engine will be increased and the engine oil
consumption reduced. Four-wheel drive (4Drive)
 Valid for vehicles: 4Drive all-wheel drive
On four-wheel driv e model
s, the engine pow-
er is distributed to all four wheels
General notes
On four-wheel drive vehicles, the engine
power is distributed to all four wheels. The
distribution of power is controlled automati-
cally according to your driving style and the
road conditions. Also see

Driving
Foresight when driving
If you think ahead when driving, you will need
t o br
ake l
ess and thus accel
erate less. Take
advantage of the inertia of the vehicle when-
ever possible, with a gear engaged. This
takes advantage of the engine braking effect,
reducing wear on the brakes and tyres. Emis-
sions and fuel consumption will drop to zero.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear.
Manual transmission: shift up from first to
second gear as soon as possible. Choosing
the right gear enables fuel savings. Select the
highest possible gear appropriate for the
driving situation (the engine should continue
functioning with cyclical regularity).
Automatic transmission: accelerate gradu-
ally and without reaching the “kick-down”
position.
Avoid driving at high speed
Avoid travelling at your vehicle

Start and driving
Save electrical energy
The engine driv es the alt
ernator
, ther
eby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*

Pin Meaning
12 Unassigned
13 Earth for pin 9 Power socket for trailer
The vehicle is fitted with a 13-pol
e po
wer
socket for the connection between the trailer
and the vehicle. With the engine running,
electrical devices on the trailer receive power
from the electrical connection (pin 9 and pin
10 of the trailer power socket).
If the system detects that a trailer has been
connected, the consumers on the trailer will
receive electricity through this connection
(pins 9 and 10). Pin 9 has a permanent live.
This powers, for example, the trailer

Type of petrol  Valid for: vehicles with petrol engines
The correct grade of petr ol is list

ed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10) 1)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least
We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available, normal 91
octane petrol (87 AKI) (with a slight power
loss) may be used.
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least. 3 If super is not available, if necessary, use nor
-
mal 91 oct ane petrol (87 AKI). In this case only
use moder at

e engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble. CAUTION
