Operation
Additional information for steep slopes and
hi l
l
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 and increase braking distance. If you drive for
a prolon

ged period on salted roads without
braking then brake carefully several times to
eliminate the layer of salt on the brakes ››› .
If the
v

ehicle remains parked for considera-
ble lengths of time, is used little, or if the
brakes are not used, there may be corrosion
on the brake discs and a build up of dirt on
the brake pads. If the brakes are not used fre-
quently, or if rust has formed on the discs,
SEAT recommends cleaning the pads and
discs by braking firmly a few times at a mod-
erately high speed. Only do this without en-
dangering vehicles behind you or any other
road users ››› .
F au
lt

s in the brake system
During braking, if you notice that the vehicle
does not react as usual (that the braking dis-
tance has increased suddenly) it may be pos-
sible that there is a fault in the braking sys-
tem. This is indicated by the warning lamp
. Take the vehicle to a specialised work-
shop immediately and have the fault re-
paired. Drive at a moderate speed and be
prepared to use more pressure on the brake
pedal, and allow for longer stopping distan-
ces.
Brake servo
The brake servo only operates when the en-
gine is running and the pressure applied by
the driver on the brake pedal increases.
142

Driving
If the brake servo does not operate or the ve-
hic l
e mu
st be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir

st 320 km, new brake pads have
not y
et reached their maximum braking ca-
pacity, and need to be “run in” first. For this,
to compensate for reduced braking efficiency
the brake pedal will have to be pressed with
more force.
● To avoid losing control of the vehicle and
caus
ing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
res
pect the safety distances between you and
other vehicles and do not cause situations re-
quiring extreme braking performance. WARNING
When brakes overheat, braking is less effi-
cient and br

aking distances increase.
● When driving on slopes, brakes can be
overlo
aded and overheat quickly.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system. ●
Non-s t

andard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
g er t o en

gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when visibility,
weather, and road and traffic conditions per-
mit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult in a severe accident.
● Never allow the vehicle to move forwards
when the engine is
switched off.
● If the brake servo does not operate or the
vehicl
e must be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate. CAUTION
● Never m ak

e the brakes “slip” by pressing
the pedal gently, if it is not really necessary
to brake. Continuously pressing on the brake
pedal will heat the brakes. This could signifi-
cantly reduce braking power, increase brak- ing distance or even result in the total failure
of the br
ak

e system.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system. Other-
wise, the brakes may overheat and fail. Only
use the brakes to reduce speed or to stop. Note
Make use, when having the front brake pads
c hec k

ed, and have the rear pads checked al-
so. The thickness of the brake pads should be
checked visually and regularly, by looking
through the openings in the wheel rims or
from underneath the vehicle. If necessary, re-
move the wheels to check them thoroughly.

nical service. Changing gear

prolonged start up, or when stopping and
starting continuously. This overheating is dis-
played with a warning lamp  in the instru-
ment panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool

having selected a gear range
When the vehicle does not move in the re-
quired direction, the system may not have
the gear range correctly engaged. Press the
brake pedal and engage the gear range
again. If the vehicle still does not move in the
required direction, there is a system malfunc-
tion. Seek specialist assistance and have the
system checked. CAUTION
● When the ge arbo

x is displayed as overheat-
ing for the first time, the vehicle must be
parked safely or must be driven at a speed of
more than 20 km/h (12 mph).
● When the warning lamp lights up and the
audible w
arning is heard, the vehicle must be
parked safely and the engine switched off.
Let the gearbox cool down.
● To prevent damage to the gearbox, driving
must
only be continued when the warning
lamps are no longer lit up. While the gearbox is overheated, starting up and driving, even
at a s

Ru nnin

g in Please observe the instructions for running-in
new components.
R u

nning-in the engine
The engine needs to be run in over the first
1,500 km. During its first few hours of run-
ning, the internal friction in the engine is
greater than later on when all the moving
parts have bedded down.
How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Throughout the life of the vehicle, it
should be driven at a moderate speed, espe-
cially when the engine is cold, as this will re-
duce engine wear and increase its useful life.
Never drive at extremely low engine speeds.
Change down to a lower gear when the en-
gine no longer runs “smoothly”. Up to 1,000
kilometres the following instructions apply:
● Do not use full throttle.
● Do not force the engine above two thirds of
its m ax

imum speed.
148

Driving
The vehicle uses more fuel in winter than in
s ummer
, ev
en when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical
wear and pollutant emissions are also espe-
cially high during this initial warm-up phase.
It is therefore best to drive off immediately af-
ter starting the engine. Doing this avoids run-
ning the engine at a high speed.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals). When purchasing engine oil, always observe
leg
al requirements and ensure that the oil is
approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical
and ecological the driving style. For example,
an additional weight of 100 kg will increase
fuel consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and unnecessa-
ry accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel consump-
tion (examples):
● Fault in engine management.
● Driving on hills. WARNING
Always adapt your speed and the distance to
the v ehic

les ahead in line with visibility,
weather conditions, the condition of the road

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 »

T y
pes of petrol The correct grade of petrol is listed inside the
fuel
t

ank flap, located on the right side of the
rear section of the vehicle.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes. If super is not available,
in an emergency y
ou
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
In all cases, you may use 98 octane petrol.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .

Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal- ers, where information on how to use them
can also be o

btained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine. » 181
