Operation
Automatic gearbox overheating
The aut om
atic
gearbox can overheat with a
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
››› .
The v
ehic

le moves forward or back despite
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
lo

w speed should be avoided. Recommended gear display

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
and the traffic situation. Engine management and ex-

The catalytic converter permits the subse-

atment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil

page 188.
● Do not tow-start the vehicle; use the starter

If you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is
work in

oad In some countries, certain safety regulations
and requir
ements

are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
● Does the vehicle need technical modifica-
tions f

or driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostic
s equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion countr
y?
● For petrol vehicles: Is unleaded petrol avail-
able at
the right octane rating?
● For diesel engines: is diesel fuel available
with a low s
ulphur content?
● Are a suitable engine oil ( ›››

page 188) and
other engine fluids complying with SEAT
specifications available in the destination
country?
● Are special tyres required in the destination

urer. Washing the vehicle
The longer substances such as insects, bird
drop
pin

gs, resinous tree sap, road dirt, in-
dustrial deposits, tar, soot or road salt and
other aggressive materials remain on the ve-
hicle, the more damage they do to the paint-
work. High temperatures (for instance due to
strong sunlight) further intensify the corro-
sive effect. The vehicle undercarriage should
also be thoroughly washed at regular inter-
vals.
Automatic car washes
Always observe the instructions provided at
the automatic car wash. The standard pre-
cautionary measures prior to entering the car
wash should be taken to avoid damage to
the vehicle (close all windows, fold in exterior
mirrors). If the vehicle is fitted with additional
components (spoiler, roof-rack, aerial, etc.),
check with the car wash supervisor whether
these can enter the car wash ››› .
The v
ehic

le paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, wear and damage to the paintwork
will depend on the type of car wash used. SEAT recommends the use of car washes
without bru

shes.
To remove traces of wax on windows and to
prevent wiper blades from scratching, please
observe the following ››› page 172, Cleaning
windows and exterior mirrors .
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
Start at the roof and work downwards. Spe-
cial car shampoo should only be used for
very persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
Sharp components on the vehicle may cause
injury .
● Pr

otect arms and hands from sharp edges
when cle
aning the vehicle undercarriage or
the interior of the wheel hubs. WARNING
After the vehicle has been washed, the brak-
ing eff ect

will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The wat er t

emperature should not exceed
+60 °C (+140 °F).
● To avoid damage to the paintwork, do not
wash the
vehicle in full sun.
● Do not use rough sponges or similar which
coul
d damage the surface to clean away the
traces of insects.
● Never wipe the headlights with a dry cloth
or spong
e, always moisten first. It is best to
use soapy water.
● Washing the vehicle in low temperatures:
When washin
g the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and
seals could freeze! CAUTION

In natural gas engines
While in gear, the fuel level indicator gauge
appears in the fuel area with which it is flow- ing at that time. When the ignition is connec-
ted, the gaug

e first changes for a few sec-
onds to the petrol area to show the actual
level of this petrol. Then, the gauge moves to
the natural gas level. After turning on the en-
gine, the gauge changes to the area corre-
sponding to the operating mode at that time.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
su lt

in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack
of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. 184
