om the en
gine.
The temperatures measured range from
-40°C to +50°C (-40°F to +122°F).
Selector lever position
The range of engaged gears of the selector
lever is shown on the side of the lever, and
on the instrument panel display. In positions
D and M, and with the Tiptronic, the corre-
sponding gear is also indicated on the dis-
play.

The recommended gear to save fuel can be
displayed on the instrument panel display
while you are driving ››› page 142.
Seat belt status display for the rear seats*
The seat belt status display on the instru-
ment panel display informs the driver, when
the ignition is switched on, whether any pas-
sengers in the rear seats have fastened their
seat belts ››› page 52.
Start-Stop system status display
The instrument panel display shows informa-
tion on the current status ››› page 160. WARNING
If the warning lamps are ignored, the vehicle
ma y

stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Park the vehicle away from traffic and en-
sure th
at no highly flammable materials are
under the vehicle that could come into con-
tact with the exhaust system (e.g. dry grass,
fuel). WARNING
Even though outside temperatures are above
freez in

g, some roads and bridges may be icy.
● At outside temperatures above +4°C
(+39°F), even when the “ice c
rystal” symbol
is not visible, there may still be patches of ice
on the road.
● Do not rely on the outside temperature in-
dicator! CAUTION
Failure to heed the warning lamps when they
appe ar m

ay result in faults in the vehicle. Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and
instructions on the display may vary.
● When several warnings are active at the
same time, the symbol
s are shown succes-
sively for a few seconds and will stay on until
the fault is rectified. Service interval display
The inspection message appears on the in-
s
trument
p

anel display ›››

T di
stinguishes between services with en-
gine oil change (Oil Change Service) and
services without engine oil change (Inspec-
tion Service). The service interval display only
gives information for service dates which in-
volve an engine oil change. The dates of the
remaining services (e.g. the next Inspection
Service or change of brake fluid) are listed on
the label attached to the door strut, or in the
Maintenance Programme.
The set service intervals have been specified
with the service dependent on time/distance
travelled.
Inspection reminder
If the inspection period is due to expire
shortly, Inspection reminder appears when
starting the ignition abbreviated to  
 and a

General instrument panel
warning in km . The number of
k ilometres
shown is the maximum number that may be
driven until the next service.
Service due
After the service date, an audible warning is
given when the ignition is switched on and
the abbreviation  displayed on the screen
flashes for a few seconds. Note
The service message disappears after a few
second s, when the en

gine is started or when
OK is pressed on the windscreen wiper lever.
Note
In vehicles whose batteries have been dis-
connect ed f

or a long period of time, it will not
be possible to calculate the next service date.
Therefore the service interval display may not
be correct. In this case, bear in mind the max-
imum service intervals permitted in the

Operation
Parking When parking your vehicle, all legal require-
ments shou
l
d be observed.
To park the vehicle
Complete operations only in the sequence
given. ● Park the vehicle on a suitable surface ›››
.
● Press and hold the brake pedal until the ve-
hicl e c

omes to a standstill.
● Apply the handbrake firmly ›››
page 139.
● For an automatic gearbox, move the selec-
tor lev
er to position N.
● Switch off the engine and release the brake
pedal.
● R

emove the key from the ignition.
● If necessary, turn the steering wheel slight-
ly to loc
k the steering.
● With a manual gearbox, engage 1st gear on
flat gr
ound and slopes, or even reverse gear
on hills, and release the clutch pedal.
● Ensure that all passengers leave the vehi-
cle, e
specially children.
● When leaving the vehicle, take all keys with
you.
● Loc

k the vehicle. Additional information for steep slopes and
hill

s
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
● On slopes, turn the front wheels so that
they are ag
ainst the edge of the kerb.
● Uphill, turn the wheels towards the centre
of the ro
ad. WARNING
The components of the exhaust system reach
ver y

high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood,
leaves,dried grass, or spilled fuel). CAUTION
● Spec i

al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam-
age the bumper or other parts of the vehicle
during manoeuvres. To avoid damage, stop
before the wheels touch the barrier or kerb.
● Special attention is required when driving
through entranc
es, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Information on the brakes
For the first 200 to 300 km, the new brak
e
p
ads have not yet reached their maximum
braking capacity, and need to be “run in”
first ››› . The slightly reduced braking effect
can be c ompen

sated for by increasing pres-
sure on the brake pedal. While running in,
the full braking distance or emergency brak-
ing distance is larger then when the brake
pads have been run in. While running in,
avoid full power braking or situations requir-
ing braking performance. For example, in
heavy traffic.
The rate of wear of the brake pads depends
to a great extent on the conditions in which
the vehicle is used and the way the vehicle is
driven. If the vehicle is used frequently in city
traffic or for short trips or driven sport style,
visit a specialised workshop regularly, more
frequently than advised in the Maintenance
Programme, to have the brake pads checked.
If you drive with wet brakes, for example, af-
ter crossing areas of water, in heavy rainfall
or even after washing the car, the effect of
the brakes is lessened as the brake discs are
wet or even frozen (in winter). At higher
speed, “dry” the brakes as quickly as possi-
ble by braking gently several times. Only do
this without endangering vehicles behind
you or any other road users ››› .
A l ay

er of salt on the discs and brake pads
will reduce the effectiveness of the brakes

Care and maintenance
consumables should be changed at a speci-
ali sed w
ork
shop. Technical services are per-
manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sum ab

les may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their origin
al container.
● Never store fluids in empty food containers
or bottles
as other people may accidentally
drink the fluid.
● Keep all fluids and consumables out of
reac
h of children.
● Read and observe the information and
warning
s given on the fluid containers.
● Only work in the open air or in well-ventila-
ted z
ones, when using products which give
off harmful vapours.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid in the main-
tenance of the vehicle. These are toxic and
highly flammable. They could lead to fire or
explosions! CAUTION
● Only u

se appropriate fluids. Do not confuse
fluids as this can cause serious malfunctions
or engine damage.
● Accessories and other components moun-
ted in front
of the air inlet reduce the cooling effect of the coolant. If the engine is running
under gr
e

at strain in high outside tempera-
tures, it could overheat. For the sake of the environment
Leaking fluids could pollute the environment.
C o l

lect any spilt fluids in suitable containers
and dispose of them in accordance with legis-
lation and with respect for the environment. Repairs and technical changes
When performing repairs and technical mod-
ific
ation
s,

SEAT's directives must be ob-
served! ››› Unauthorised modifications to the electronic
c
omponents
or sof

tware in the vehicle may
cause malfunctions. Due to the way the elec-
tronic components are linked together in net-
works, other indirect systems may be affec-
ted by the faults. This may significantly affect
the vehicle's performance, increase compo-
nent wear and could mean that the vehicle
registration documents are no longer valid.
Your SEAT Official Service cannot be held lia-
ble for any damage caused by technical mod-
ifications or repairs performed incorrectly.
The SEAT Official Service does not accept lia-
bility for damage resulting from technical
modifications or repairs performed incorrect- ly; neither is the SEAT warranty valid in these
case

s.
SEAT recommends you have any technical
modifications or repairs performed at a SEAT
Official Service and that you use genuine
SEAT spare parts ®
.
Vehicles with special accessories and equip-
ment
The manufacturers of additional equipment
guarantee that the equipment complies with
applicable laws and regulations with respect
to the environment, in particular Directives
2000/53/CE and 2003/11/CE. The first direc-
tive governs the disposal of end-of-life vehi-
cles while the second refers to the restric-
tions on the marketing and use of certain
dangerous substances and preparations.
The vehicle owner should keep the documen-
tation for the additional equipment safely
and hand it over to the scrap yard at the end
of the vehicle's service life. This ensures that
any additional equipment mounted in end-of-
life vehicles is correctly disposed of with re-
spect for the environment. WARNING
Repairs or modifications which are not per-
formed c orr

ectly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the driver assist systems. This
could result in serious accident. » 165

Care and maintenance
The optimal reach of the equipment is only
ac hiev
ed w
ith an external aerial.
Check first with a specialised workshop that
understands the technical possibilities of in-
stallation if you wish to use a two-way radio
with a transmitting power of over 10 watts.
SEAT recommends taking your car in for tech-
nical service.
All legal requirements, together with the in-
structions for the use of two-way radios must
be observed. WARNING
If the two-way radio is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury.
● While driving, two-way radios must be se-
curely
fastened in position, outside the air-
bags deployment zones, or safely stowed
away. WARNING
When using a two-way radio without a con-
nection to an e xt

erior aerial, the maximum
permitted levels of electromagnetic radiation
may be exceeded. This is also the case if the
aerial has not been correctly installed.
● You should only use a two-way radio inside
the vehic
le if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
u
nit
s Your vehicle is fitted at the factory with a ser-
ies
of

electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The v ehic

le control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli- ances connected in the vehicle, it is possible
to send the v

ehicle position. If the control
unit records an accident with airbag activa-
tion, the system may automatically send a
signal. This will depend on the network oper-
ator. Normally, transmission is only possible
in areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. Vehicles with airbag systems can store
data relating to impact speed, seat belt sta-
tus, seat positions and airbag activation
times may be stored, etc. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle owner
and, in some countries, they are governed by
local legislation.
Reprogramming control units
On the whole, all the data required for the
component management is stored in the con-
trol units. The programming of certain con-
venience functions, such as the turn signals,
individual door opening and instructions on
the display can be modified using special »
