Operation
If the engine does not start immediately,
sw it
c
h the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ››› page 104, Fuses. WARNING
● Never s t

art or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is
running.
● Never use “cold start sprays”, they could
explode or c
ause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr
es to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in or
der to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
engine w ith the

vehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions. Starting diesel engines
The engine can only be started using a genu-
ine S

T key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depre s

s the clutch pedal thor-
oughly and hold it in this position for the

Glow plug system for diesel engines
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp goes out.
Starting a diesel engine after the fuel tank
has run dry
If the fuel tank has been completely run dry,
it may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
Observe the safety warnings ›››
in Starting
petro l
engines on page 174. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed

Bef or
e attempting to push-start or tow a ve-
hicle in order to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
en gine w ith the

vehicle stationary. You
should drive off as soon as you start the en-
gine. This helps the engine reach operating
temperature faster and reduces emissions. Immobiliser “SAFE”*
1)The electronic immobiliser prevents unau-
thori
sed per

Inside the key 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.
The engine can only be started using a genu-
ine SEAT key with its correct code.
If the following message* is shown on the in-
strument panel display: SAFE, the vehicle
cannot be started. The engine can, however, be started if the
appropri

ate coded SEAT genuine key is used. Note
A perfect operation of the vehicle is ensured
if g enuine

SEAT keys are used. Switching off the engine

itching the engine off, the radiator
fan may run on for up to 10 minutes. It is also
possible that the fan turns itself on once
more if the coolant temperature increases
due to the heat accumulated in the engine
compartment or due to its prolonged expo-
sure to solar radiation. WARNING
● Never sw it

ch the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is ru
nning. With the engine switched off,
more strength is needed to brake. As normal
brake operation cannot be performed, risk of
accidents and serious injury may exist. ●
The st eerin

g lock can be immediately
blocked once the key is removed from the ig-
nition. The vehicle cannot be steered. Risk of
accident.
● Power-assisted steering does not work
when the engine is
off, and more strength is
needed to turn the wheel.
● If the key is removed from the ignition lock
the steerin
g lock could be engaged and vehi-
cle steering would not work. CAUTION
● When the en gine ha

s been running under a
heavy load for a long period, heat can accu-
mulate in the engine compartment and cause
engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off.
● If the vehicle is stopped and the Start-Stop
syst
em* switches off the engine, the ignition
remains switched on. Make sure that the igni-
tion is switched off before leaving the vehi-

ruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. Note
● In v ehic

les with an automatic gearbox, you
can control whether the engine should switch
off or not by reducing or increasing the brake
force applied. While the vehicle remains stop-
ped, the engine will not stop if the brake ped-
al is slightly pressed, in traffic jams with fre-
quent stopping and starting for example. As
soon as strong pressure is applied to the
brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes

The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Trailer maximum electricity consumption

You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service fluids and consumables replaced by a Techni-
cal

Service. Please observe the relevant in-
structions ››› page 259. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.

g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coo
lant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● App

ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
 page 72.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off

Never c o

ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
