Additiona
l information for steep ascents and
descents
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, t
urn the front wheels so that
they are against 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 (100 to 200
mi
l
e

s), new brake pads have not yet reached their maximum braking capacity, and need to
be “run in” firs

t ››› . The slightly reduced
br ak
in
g effect can be compensated for by in-
creasing pressure on the brake pedal. While
running in, the full braking distance or emer-
gency braking distance is larger then when
the brake pads have been run in. While run-
ning in, avoid full power braking or situations
requiring 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 a
y

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

use the brakes to reduce speed or to stop. Note
When checking the front brake pads, take the
time t o al

so check the rear brake pads. 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-

Selector lever locking
The g e
ar sel
ector lever lock prevents, in P or
N, a gear selection from being inadvertently
engaged and the vehicle moving off acciden-
tally.
To release the gear selector lever lock, press
and hold the brake pedal with the ignition
on. Press simultaneously on the selector lev-
er lock.
The selector lever lock is not engaged if it is
moved quickly through position N (e.g. when
shifting from R to D). This makes it possible,
for instance, to “rock the vehicle backwards
and forwards” if it is stuck in snow or mud.
The selector lever lock engages automatically
if the brake pedal is not pressed and the lev-
er is in position N for more than about one
second at a speed of less than 5 km/h
(3 mph).
In vehicles with a DSG ®
automatic gearbox,
on rare occasions the selector lever lock may
not engage. In this case, the transmission is
locked to prevent the vehicle from moving ac-
cidentally. The green control light  flashes
and an information text is displayed. Proceed
as follows to engage the selector lever lock:
● Press the brake pedal and then release. WARNING
Placing the selector lever in an incorrect posi-
tion ma y

cause loss of control of the vehicle
and a serious accident.
● Do not press the accelerator when engag-
ing a ran
ge of gears.
● With the engine running and a range of
gear
s selected, the vehicle will move off
when the brake pedal is released.
● Never select reverse gear or the parking
lock whi
le driving. WARNING
Unintentional movements of the vehicle
cou l

d cause serious injury.
● As a driver, you should never leave your ve-
hicle if
the engine is running and a gear range
is engaged. If you have to leave your vehicle
while the engine is running, you must apply
the electronic parking brake and engage
parking lock P with the selector lever.
● While the engine is running and with the D,
S or R rang
e of gears selected, keep the brake
pressed to keep the vehicle at a standstill.
Transmission is not totally interrupted either
when the vehicle is idling or when the vehicle
“continues moving forwards”.
● Never engage the R or P gear ranges when
the vehic
le is moving.
● Never leave the vehicle with the gear selec-
tor in N. The
vehicle may move downhill re-
gardless of whether the engine is switched
on or not. CAUTION
If, when the vehicle is at a standstill, the
electr onic

parking brake is not applied and
the brake pedal is released while in position
P, the vehicle may move a few centimetres
forwards or backwards. Note
If, while driving, the selector lever is acciden-
ta l

ly placed in position N, lift your foot off the
accelerator. Wait until the engine is running
at idle speed before selecting a new gear
range. 195

Protection against overloading the DSG ®
6-
gear automatic gearbox
When the clutch is overloaded, the vehicle
begins to jerk and the selector lever position
indicator begins to flash. To prevent damage
to the clutch, this interrupts the power trans-
mission between the engine and the gear-
box. There is no more traction and it is not
possible to accelerate. If the clutch is opened
automatically due to overloading, press the
brake pedal. Wait a few seconds before start-
ing to move again.
Kick-down
The kick-down system provides maximum ac-
celeration when the gear selector lever is in
the positions D, S or in the Tiptronic position.
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. Launch-Control Programme
The Launch-C

ontrol programme enables max-
imum acceleration while at a standstill.

This could cause loss of control of the vehicle
resulting in an accident and considerable
damage.
● Only use kick-down and rapid acceleration
when weather c
onditions, surface conditions
and traffic conditions permit; accelerate and
drive in a manner that does not endanger
other road users.
● Please remember that the driven wheels
can slip and the
vehicle can skid if the ASR is
turned off, especially on slippery ground.
● Turn on the ASR after accelerating! CAUTION
● If y

ou stop on a hill with a gear range en-
gaged, do not try to prevent the vehicle from
rolling back by pressing on the accelerator.
This could cause overheating and damage the
automatic gearbox.
● Never allow the vehicle to move with the
gear sel
ector lever in N, especially with the
engine turned off. The automatic gearbox will
not be lubricated and could be damaged. Recommended gear display

nning-in the engine
The engine needs to be run-in over the first
1500 km (1000 miles). During its first few
hours of running, 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
1500 km (1000 miles) influences the future
engine performance. Throughout the life of
the vehicle, it should be driven at a moderate
speed – especially when the engine is cold –
this will reduce engine wear and increase its
useful life. Never drive at extremely low en-
gine speeds. Always engage a lower gear
when the engine works “irregularly”. For the
first 1000 km or 600 miles, please note: »

Driving
In addition, “skipping” gears when shifting
up help s
t
o 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. In
vehicles which have the Start-Stop function
on, the engine switches off automatically
when the vehicle is not moving. Think ahead and “flow” with the traffic
Frequent ac
celeration and braking considera-
bly increase fuel consumption. If you think
ahead as you drive and keep a safe distance
from the vehicle 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
conditionin g 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
for the vehicle is not too different to the out-
side temperature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with all the windows
open. Only then should you close all the win-
dows and switch on the air conditioning.
Keep windows closed when travelling at high
speeds. Driving with the windows open in-
creases fuel consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window and the
winds
creen heating when the windows have
demisted and are free of ice.
● Do not leave the auxiliary heater switched
on when the vehic
le is moving ››› page 180.
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. »

In order to reduce blocking of the diesel par-
ticulate filter, some vehicles with an automat-
ic gearbox may increase the engine speed
slightly to start cleaning the filter automati-
cally. The  control lamp will not light up in
this case.
Control lamp 
If the  control lamp lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h
(37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp  does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING

oad In some countries, certain safety regulations
and r
equir
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 an
y SEAT dealers in the destina-
tion country?
● 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 274) and
other engine fluids complying with SEAT
specifications available in the destination
country?
● 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-

204

Driver assistance systems
● Do not driv
e f
aster than a pedestrian.
● Do not stop in the water, use reverse gear
or switc
h off the engine.
● Oncoming traffic will cause waves which
raise the l

to cross the water.
The Start/Stop system must be deactivated
when driving through flooded areas 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-
ses c

g and stability systems
Brake assist systems The brake assist systems ESC, ABS, BAS, ASR
and EDL on
ly

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 ve-
hicle by braking individual wheels or by re-
ducing the engine torque.
The ESC has limits. It is important to realise
that the ESC is also subject to the laws of
physics. ESC will not be able to deal with all
situations with which drivers may be faced.
For example, if the road surface changes sud-
denly 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-
planing”), the ESC will not be able to assist the driver to control the vehicle as the loss of
adher
enc

e with the road surface will 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.
When driving with a trailer, ESC does not pro-
vide the same amount of vehicle control as
without a trailer.
Adjust your speed and driving style to road,
traffic and weather conditions. ESC cannot
push the limits of the laws of physics; im-
prove the transmission available or maintain
the vehicle on the road if a lack of driver at-
tention creates an inevitable situation. Other-
wise, ESC assists in maintaining vehicle con-
trol in extreme situations and uses the move-
ments 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 system cannot pro-
vide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC. The ESC is always
on. The ESC should only be turned off using
the ASR button ›››
Fig. 204 when traction is
insufficient. Always remember to turn on the
ASR once more when the vehicle has traction
again. »

WARNING
Driving at high speed on icy, slippery wet
grou nd c
an result in loss of vehicle control
and serious injury to the driver and passen-
gers.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC, provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
law
s of physics. Even with ESC and other sys-
tems, slippery and wet roads will always be
dangerous.
● Driving to quickly on wet ground can result
in the wheels lo
sing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if
, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely eff
ective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for ex
ample on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. WARNING
The effectiveness of the ESC can be consider-
ably r

educed if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components
to the vehicle can affect opera-
tion of the ABS, BAS, ASL EDL and ESC.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASL EDL and
ESC, as well as their effectiveness.
● Likewise, the effectiveness of ESC depends
on the use of s
uitable tyres ››› page 287. Note
● To en s

ure that the ESC and ASR work prop-
erly, all four wheels must be fitted with iden-
tical tyres. Any differences in the rolling radi-
us of the tyres can cause the system to re-
duce engine power when this is not desired.
● If a malfunction should occur in the ABS,
the ESC, EDL and ASR w
ill also be out of ac-
tion.
● Noises may be heard while any of the
above sy
stems are operating. Switching ASR on and off

on u

sed to switch ASR on and off (vehi-
cles with ESC) The electronic stability control ESC consists
of
ABS, EDL
and ASR and on

ly works when
the engine is running.
The ASR can be switched off while the engine
is running by pressing the   button
››› Fig. 204. The ASR (and similar) is only
switched off when the required traction is not
obtained:
● When driving through deep snow or on
loose grou
nd (gravel, etc.).
● When “freeing” a trapped vehicle.
Turn the ASR bac
k on by pressing the
  button ››› Fig. 204.
