Operation
Only change gears when the vehicle is at a
s t
andstill. To change the position of the se-
lector lever, press the brake pedal and switch
on the ignition.
 - Reverse gear
Reverse gear is engaged.
Only put in reverse when the vehicle is at a
standstill. If not it could result in serious
damage.
 - Neutral
The gearbox is in neutral. No movement is
transmitted to the wheels and the engine
does not act as a brake.
 - Standard forwards driving position (nor-
mal programme)
The gears are changed (up and down) auto-
matically. The gear shifts are determined by
the engine load, your individual driving style
and the speed of the vehicle.
 - Standard forwards driving position
(sports programme)
The shift up to a higher gear is automatically
delayed and the shift down is faster with re-
spect to the D range of gears, to take full ad-
vantage of the engine power. The gear shifts
are determined by the engine load, your indi-
vidual driving style and the speed of the ve-
hicle. Selector lever locking
The gear 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. 194

Operation
● Gently p
u
ll the selector lever back to
change down a gear.
● OR: reduce using the steering wheel pad-
dle
s ››› Fig. 204 ››› page 195.
Back-up mode
If all the selector lever positions on the in-
strument panel display are shown with a
light-coloured background, this means there
is a fault in the system. The automatic gear-
box will operate in back-up mode. When the
backup programme is activated, it is possible
to drive the vehicle, however, at low speeds
and within a selected range of gears.
For the DSG ®
dual clutch gearbox, in some
cases, this may mean that the reverse gear
does not engage . The gearbox should be
checked by a specialised workshop as soon
as possible.
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-Control programme enables max-
imum acceleration while at a standstill.
● Switch off the ASR ›››
page 187.
● Press and hold the brake pedal with your
left
foot.
● Place the selector lever in position S or Tip-
tronic
.
● Press the accelerator with the right foot un-
til the
vehicle reaches an engine speed of ap-
proximately 3200 rpm.
● Lift the left foot off the brake ›››
. The ve-
hic l
e s
tarts with maximum acceleration.
● Turn on the ASR after accelerating! 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 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

R u

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:
● Do not use full throttle.
● Do not force the engine above two thirds of
its m ax

imum speed. ●
Do not to
w a trailer.
Between 1000 and 1500 kilometres (600 to
1000 miles), gradually increase power until
reaching the maximum speed and high en-
gine speeds.

ac
cessories
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.
● Trailer towing. WARNING

Driv ing abr

oadIn 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 271) 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-
ing the flooded z
one. The water should never
come above the lower edge of the bodywork
››› .●
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
evel of the water, making it difficult
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
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. 202

Operation
front wheels are turned, the normal ABS is
activ at
ed.
Br
ake 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
ABS to be activated more quickly and effec-
tively.
¡Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control when accelerating (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. The ASR makes
some situations easier, for example, when
starting, accelerating or going uphill, even in
unfavourable road conditions.
The ASR can be switched on or off manually
››› page 205.
Electronic differential lock system (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel and directs the power to the other drive
wheels. T
o prevent the disc brake of the
braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive
loads. The EDL will switch on again automati-
cally when the brake has cooled down.
Electronic drive torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected. 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. 204

Driver assistance systems
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 284. 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.
