Operation
to the gear display indicating whether you
should change up or down. Note
The gear change indication should not be tak-
en into account when quick acceleration is re-
quired (for example when overtaking). Odometer
The left-hand counter in the display registers
the total amount of distance covered by the
vehicle.
The right-hand counter registers the short
journeys. The last digit indicates steps of 100
metres. The trip recorder counter may be re-
set by holding down the reset button for a
few seconds.
Flexible service interval display Vehicles with
Service intervals dependent on
time/distance travelled already have certain
service intervals set. The intervals are calcu-
lated individually in vehicles with LongLife
service .
The ser v
ice interval display only indicates the
dates of services that include engine oil
change. The dates of all other services, such
as the Inspection Service or brake fluid change, appear in the sticker on the door pil-
lar or in the Maintenance Programme.
A
Service pre-warning will appear in the od-
ometer if a service is due soon. A “spanner”
symbol appears and the display “km” with
the distance that can be driven until the next
service appointment is due. This signal
changes after around 10 seconds. A “clock
symbol” appears and the number of days un-
til the service appointment should be carried
out. The following message is shown in the
instrument panel display*:
Service in
[XXXX]
kmor
[XXXX]
days
The service message will disappear approxi-
mately 20 seconds after the ignition is
switched on or the engine is running. The
normal display can be resumed by briefly
pressing the reset button on the trip counter
or by pressing the OK button on the steering
wheel controls.
With the ignition on, you can check the cur-
rent service message at any moment in the
Vehicle status menu or turning the reset but-
ton to access the service display. An
overdue service
is indicated by a minus
s

ign in front of the mileage or day informa-
tion.
Indications for vehicles with LongLife service
Technical progress has made it possible to
considerably reduce servicing requirements.
With the LongLife System, SEAT ensures that
your vehicle only has an Interval Service
when it is necessary. The length of the Inter-
val Services (max. 2 years) is determined by
factors such as conditions under which the
vehicle is used and personal driving style.
The service pre-warning will first appear 20
days before the date on which the service is
due. The distance travelled is rounded off to
the nearest 100 km and the time to full days.
The current service message can only be con-
sulted 500 km after the last service. Until
that time, only dashes are displayed. Note
● If you reset the display manually, the next
service interval will be indicated after
15,000 km or one year and will not be calcu-
lated individually.
● Do not reset the display between service
intervals as the display will otherwise be in-
correct. 48

Dash panel
●
In LongLife Service vehicles, if the battery
is disconnected for a long period, the days re-
maining until the next service cannot be cal-
culated. Therefore, the service message dis-
plays on the instrument panel may be incor-
rect. Take into account the maximum author-
ised service intervals. Warning or information message in
the display
The system runs a check on certain compo-
nents and functions when the ignition is
switched on and while the vehicle is moving.
Functional faults are indicated by symbols
with warning or information messages in the
display. An audible warning is given in cer-
tain cases.
Warning symbols
There are red warning symbols (priority 1)
and yellow warning symbols (priority 2).
Information text
In addition to warning messages given on a
fault, you will receive information in the dis-
play on procedures or will be asked to carry
out certain tasks. Note
In the case of screens without warning or in-
formation messages, faults are indicated ex-
clusively by the control lamps. Warning messages, Priority 1 (red)
If one of these faults occurs, the warning
lamp will light up or flash and will be accom-
panied by
three audible warnings. This is a
danger warning. Stop the vehicle and switch
off the en
gine. Check the fault and correct it.
Obtain professional assistance if necessary.
If several priority 1 faults are detected at the
same time, the symbols will be displayed one
after the other for about 2 seconds at a time
and will continue until the fault is corrected.
No menus will be shown in the display for the
duration of a priority 1 warning message.

Driving
WARNING
● The ignition key must NOT be removed from
the lock until the vehicle comes to a stand-
still. Otherwise, the steering could be imme-
diately blocked- Risk of accident!
● Always remove the key from the ignition
when leaving the vehicle, even if only for a
short period. This is especially important if
children or disabled people are left alone in
the vehicle. They could accidentally start the
engine or work electrical equipment such as
the electric windows, resulting in an acci-
dent.
● Unsupervised use of the key could start the
engine or any electrical system, such as the
electric windows. This could result in serious
injury. CAUTION
The starter motor will only work when the en-
gine is stopped (ignition key position 2 ).
Electronic immobiliser
The electronic immobiliser prevents unau-
thorised persons from driving the vehicle.
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.
Note
A perfect operation of the vehicle is ensured
if genuine SEAT keys are used. Starting petrol engines
The engine can only be started using a genu-
ine SEAT key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depress the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to the starting posi-
tion ›››
page 120 .
– Let
go of the ignition key as soon as the en-
gine starts; the starter motor must not run
on with the engine.
After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. If the engine does not start immediately,
switch 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 196, Fuses. WARNING
● Never start 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 cause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine is 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 metres 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 order to start it, you should first try to
start it using the battery of another vehicle.

Unsuitable maintenance and cleaning of vehi-
cle components may impair proper operation
of safety equipment and cause serious injury.
● Maintain and clean vehicle components ac-
cording to the manufacturer's instructions.
● Only use approved or recommended clean-
ing products. CAUTION
● Cleaning products which contain solvents
have a corrosive effect and may damage the
material irreparably. ●
Stains and dirt containing aggressive sub-
stances or solvents attack the material and
may damage it irreparably, even when they
are cleaned quickly.
● Dirt and stains should not be allowed to dry
and should be cleaned as quickly as possible.
● In the case of stubborn stains, take the ve-
hicle to a specialised workshop to avoid dam-
age. Treating your upholstery
To treat and maintain your seat upholstery,
keep the following in mind
››› :
Before entering the vehicle, close any Velcro
fasteners that might snag on the upholstery
or trim fabric. Any open Velcro fasteners may
damage the trim or upholstery fabrics.
To prevent damage, avoid direct contact be-
tween sharp decorative objects and the up-
holstery and trim fabrics. Decorative objects
include zips, rivets and rhinestones on cloth-
ing and belts.
From time to time, clean the dust that gath-
ers in the perforations, folds and seams so
that the surfaces of the seats are not dam-
aged by its abrasive effect.
Make sure clothes are colour-fast to avoid
them running and staining the upholstery.
This is especially important if the upholstery
is light in colour. CAUTION
If you ignore this checklist, which is impor-
tant for maintaining your seat upholstery, the
fabric may be damaged or stained.
● Consult the checklist and carry out the op-
erations it describes. Note
SEAT recommends you take the vehicle to a
specialised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. How to clean the upholstery, trim
fabrics and Alcantara
® Cleaning the fabric on heated seats and
electrically adjustable seats or seats with
airbag components
There may be important airbag components
and electrical connections inside the driver
seat, passenger seat and possibly the outer
rear seats. If these seats and seat backrests
are damaged, or are cleaned and are treated
incorrectly, or if they get wet, the vehicle
electric system may be destroyed and the air-
bag system damaged

could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel fuel
by the diesel manufacturer in accordance
with standard EN 590 or DIN 51628 is author-
ised and will not cause damage to the engine
or the fuel system.
● The diesel engine has been designed to be
used exclusively with diesel fuel conforming
to standard EN 590. Never refuel or use pet-
rol, kerosene, fuel oil or any other type of
fuel. If you accidentally fill up the vehicle
with the wrong type of fuel, do not start the
engine. Seek assistance from specialised per-
sonnel. The composition of these fuels may
severely damage the fuel system and the en-
gine. Winter operation
Winter-grade diesel
When using “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0 °C (+32 °F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-grade diesel fuel” is available in some
countries during the cold months. It can be
used at temperatures as low as -22 °C (-8 °F).
In countries with different climatic conditions
the diesel fuel generally sold has different
temperature characteristics. Check with the
Technical Services or filling stations in the
country concerned regarding the type of die-
sel fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration in winter. This ensures that the fuel
system remains operational to approx. -24 °C
(-11 °F), provided you use winter-grade diesel
which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11 °F), simply leave
the vehicle in a heated area for a while.
CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or similar additives with diesel fuel. LPG system (Liquefied

Advice
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 147 . The engine compart-
ment of
the vehicle is a hazardous area.
››› .
WARNING
All work on the engine or in the engine com-
partment, 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 coolant 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.
● Apply the handbrake and move the gear
lever to 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 exhaust 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 190. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion 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 large, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must 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
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. CAUTION
When topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! 164

Checking and refilling levels
For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet
