The kickdown system provides maximum ac-
celeration when the gear selector lever is in
the position D, or in the Tiptronic position M.
When the accelerator pedal is pressed right
down, the automatic gearbox will shift down
to a lower gear, depending on road speed
and engine speed. This takes advantage of the maximum acceleration of the vehicle
›››
.
When the ac c
el
erator is pressed to the floor,
the automatic gearbox shifts to the next gear
only after the engine reaches the specified
maximum engine speed. WARNING
Rapid acceleration can cause loss of traction
and skid din

g, especially on slippery ground.
This could cause loss of control of the vehicle
resulting in an accident and serious injury.
● Always adapt your driving style to suit the
flow of tr
affic.
● Only use the kick-down function or rapid
accel
eration if visibility, weather, road and
traffic conditions so permit.
● Never put other road users in danger by ac-
celer
ating or with your driving style. CAUTION
If you stop on a hill with a gear range engag-
ed, do not tr y

to prevent the vehicle from roll-
ing back by pressing on the accelerator. Oth-
erwise, the automatic gearbox may overheat
causing damage. 140

Driving
Automatic gearbox malfunction Back-up programme
When autom
atic
gearbox warning and indica-
tion lamps light up on the instrument panel,
there may be a system malfunction
››› page 137. In the event of some faults the
automatic gearbox functions using a backup
programme. When the programme is activa-
ted, it is possible to drive the vehicle, howev-
er, at low speeds and within a selected range
of gears.
With the manual gearbox, in some cases it is
not possible to drive with all the gears .
In all cases the automatic gearbox must be
checked at a specialised workshop.
Automatic gearbox overheating
The automatic 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 dir

ection, 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 slow speed should be avoided. Recommended gear display

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 max
imum speed.
Between 1,000 and 1,500 kilometres, gradu-
ally increase power until reaching the maxi-
mum speed and high engine speeds.

gFig. 147
Fuel consumption in litres per
100 km at 2 diff
er

ent outside temperatures Fuel consumption, environmental impact and
en
gine, br
ak

e and tyre wear depend largely
on three factors:
● Personal driving style.
● Conditions of use (weather, road surface).
● Technical requirements.
Saving
s of up to 25% in fuel consumption
are possible with an appropriate driving style
and the adoption of certain simple tips.
Changing gear early
General instructions: The highest gear is al-
ways the most economical. As a guide, for
most vehicles at a speed of 30 km/h
(19 mph), drive in third gear, at 40 km/h (25 mph) in fourth gear and at 50 km/h
(31 mph) in fifth ge

ar.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.
Do not wait until the last moment before
changing gear. Only use first gear when you
move off and change to second gear quickly.
Avoid the kick-down function in vehicles with
automatic gearbox.
Vehicles with a gear display help to achieve
an economical driving style as the display in-
dicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the
fuel supply is stopped and consumption is
reduced.
Allow the vehicle to roll without accelerating,
for example when approaching a red traffic
light. However, if the vehicle is rolling too
slowly or the distance is too long, the clutch
pedal should be pressed to declutch. The en-
gine will then operate at idle speed.
If the vehicle is going to be at a standstill for
a period of time, switch off the engine; for ex-
ample, while waiting at a level crossing.
Think ahead and “flow” with the traffic
Frequent acceleration and braking considera-
bly increase fuel consumption. If you think ahead as you drive and keep a safe distance
from the v
ehicle in front, it is possible to slow
down by simply lifting your foot off the accel-
erator. This eliminates the need for constant
braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The
more you drive at a constant speed, the lower
the fuel consumption.
When driving on the motorway, it is more effi-
cient to drive at a constant and more moder-
ate speed than to be continuously accelerat-
ing and braking. As a general rule, you will
reach your destination just as quickly when
you drive at a constant speed.
The cruise control function helps you to ach-
ieve a constant style of driving.
Moderate use of additional devices
It is important to travel in comfort, but con-
venience systems should be used ecological-
ly.
Some equipment, when connected, increase
fuel consumption considerably, for example:
● Air conditioning cooling system: If the air
conditioning sy
stem is required to cool to
significantly lower temperatures than the true
outside temperature, it will require a large
amount of energy from the engine. Therefore,
we recommend that the selected temperature »

Operation
for the vehicle is not too different to the out-
s ide t
emper
ature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window when it
is not
moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 147 shows the difference in consump-
tion for the same journey at +20 °C (+68 °F)
and at -10 °C (+14 °F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips. The vehicle uses more fuel in winter than in
summer, 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.

The catalytic converter permits the subse-
quent tr
e

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

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
g perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving abroad
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 186) and
other engine fluids complying with SEAT specifications available in the destination
countr

y?
● Will the navigation system fitted at the fac-
tory
operate correctly in the destination coun-
try with the available navigation data?
● Are special tyres required in the destination
countr
y? CAUTION
SEAT does not accept liability for any damage
to the v

ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z
one. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water. ●
Disc
onnect the Start-Stop system whenever
crossing water. WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “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.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-

Driver assistance systems
Driver assistance systems
Br ak
in
g and stability systems
Brake assist systems The assisted braking systems ESC*, ABS,
EBV
, B

AS, ASR, TC and EDL only operate when
the ignition is switched on. They contribute
significantly to increasing active safety.
Electronic Stability Control (ESC)*
ESC* reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions.
ESC* detects critical handling situations,
such as understeer, oversteer and wheelspin
on the driven wheels. The system stabilises
the vehicle by braking individual wheels or
by reducing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly then ESC* will not be useful in all cases. If
the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC* will
not provide assistance in the same way as on
dry ground. If the vehicle loses its grip on the ground and moves on a film of water (“aqua-
pl
anin

g”), the ESC* will not be able to help
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the
road before ESC* can intervene then the sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops thus helping the driver to steer the vehicle
and maintain c
ontrol. This means that, even
during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remov
e your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
brakin
g force!
● Maintain vehicle direction when braking
ful
ly.
● When the brake pedal is released or when
the brake f
orce is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
expect the ABS to reduce the braking dis-
tance under any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the »1)
