Introduction Your vehicle is equipped with an electronical-
ly
c
ontr

olled manual gearbox. Torque be-
tween the engine and the gearbox is trans-
mitted via two independent clutches. They re-
place the torque converter found on conven-
tional automatic gearboxes and allow for
smooth, uninterrupted acceleration of the ve-
hicle. The tiptronic system allows the driver to
ch

ange gears manually if desired
››› page 195, Engaging gears with the trip-
tonic mode*.
Selector lever positions Read the additional information carefully
›› ›

 page 49
The selector lever position engaged is high-
lighted on the display in the instrument clus-
ter. With the selector lever in the manual
gearbox positions G, D, E and S, the engaged
gear is also indicated on the display.
P – Parking lock
When the selector lever is in this position,
the driven wheels are locked mechanically.
The parking lock must be engaged only when
the vehicle is stationary ››› .
The int erloc
k

button (the button on the selec-
tor lever handle) must be pressed in and si-
multaneously the brake pedal must be de-
pressed before moving the selector lever ei-
ther in or out of position P.
R – Reverse gear
Reverse gear must be engaged only when the
vehicle is stationary and the engine is idling
››› .To move the selector lever to position R, the
int
erloc
k

button must be pressed in and at
the same time the brake pedal must be de-
pressed. The reverse lights come on when
the selector lever is in the R position with the
ignition on.
N – Neutral (idling)
With the selector lever in this position, the
gear is in neutral.
D/S – Permanent drive (forward) position
The selector lever in the D/S position enables
the gears to be controlled in normal mode (D)
or Sport (S). To select Sport mode (S), move
the selector lever backwards. Moving the lev-
er again will select normal mode (D). The se-
lected driving mode is shown on the instru-
ment panel display.
In normal mode (D), the gearbox automatical-
ly selects the best gear ratio. This depends
on the engine load, the road speed and the
dynamic gear control programme (DCP).
Sport mode (S) must be selected for a sporty
driving style. This setting makes use of the
engine's maximum power output. When ac-
celerating the gear shifts will be noticeable.
Press the brake pedal to move the selector
lever from N to D/S when the vehicle is sta-
tionary or at speeds below 3 km/h (2 mph)

Operation
Under certain circumstances (e.g. when driv-
in g in mou
nt
ains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 195, in order to manually select gear
ratios to suit the driving conditions. WARNING
● Tak e c

are not to accidentally press the ac-
celerator pedal when the vehicle is stopped.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● Never move the selector lever to R or P
when driving. F
ailure to follow this instruc-
tion could result in an accident.
● With selector lever in any position (except
P) the vehic
le must always be held with the
foot brake when the engine is running. This is
because an automatic gearbox still transmits
power even at idling speed, and the vehicle
tends to “creep”. The accelerator pedal must
on no account be pressed inadvertently when
a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● While you are selecting a gear and the vehi-
cle i
s stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if
the engine is running and a gear is en- gaged. If you have to leave your vehicle while
the engine i
s

running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the sel
ector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 298, Working in the engine compart-
ment. Note
● If the sel ect

or lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be int
errupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ›››

Operation
Changing gear manually with the selector
l ev
er
It
is possible to change to tiptronic mode,
both when the vehicle is stopped and while
driving.
– To switch to tiptronic mode, move the se-
lector l

ever from position D/S to the right.
As soon as the change is made the selector
level will be shown in the position M on the
instrument panel display (for example M4
means that the fourth gear is engaged).
– Move the selector lever forwards + to se-
l ect
a higher g

ear ››› Fig. 182.
– Move the selector lever backwards – to
sel ect
a lo

wer gear.
Changing gear manually with the gearshift
paddles*
The gearshift paddles can be used when the
selector lever is in the position D/S or M.
– Press the gearshift paddle + to select a
higher g e
ar ›

›› Fig. 183.
– Press the gearshift paddle – to select a
lo w
er g

ear.
– With the selector lever in position D/S, if no
pad

dle is operated during a short period of
time, the gearbox control system switches
back to automatic mode. To switch to per-
manent manual gear change using the
gearshift paddles, move the selector lever
from position D/S to the right. When accelerating, the gearbox automatical-
ly shifts

up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
over-revving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.
Driving tips The gearbox changes gear ratios automatical-
ly
a
s

the vehicle moves.
The engine can only start with the selector
lever in position P or N. At low temperatures,
below -10°C (50°F), the engine can only start
with the selector lever in position P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the
button on the sel

ector lever handle), move
the selector lever to the desired position,
for instance D ›››
page 193, and release the
interlock button.
– Wait for the gearbox to engage the gear (a
slight mo

vement can be felt).
– Release the brake and press the accelerator
›››
.Stopping briefly
– Apply the foot brake to hold the vehicle
briefly when s
t

ationary (for instance at traf-
fic lights). Do not press the accelerator.
Stopping/Parking
If the driver door is opened and the selector
lever is not in position P, the vehicle could
move. The driver message will be:  Gear
change: selector lever in the
drive position! . Additionally, a buzzer
will sound.
– Press and hold the brake pedal ›››
.
– Apply the handbrake.
– Move the selector lever to position P.

vent
the vehicle from “moving backwards;
if necessary, apply the handbrake” ››› .
Do not tr y
t

o stop the vehicle “rolling back”
by increasing the engine speed when a
gear is engaged (pressing the accelerator)
››› .

Driving
Driving down hills: in some s it
uation s (on
mountain roads or when towing a trailer or
caravan) it can be advantageous to switch
temporarily to the manual gearbox pro-
gramme so that the gear ratios can be selec-
ted manually to suit the driving conditions
››› .
On l ev
el

ground it is sufficient to move the
selector lever to position P. On slopes, first
engage the parking brake and then put the
selection lever into the P position. This
avoids overloading the locking mechanism
and it will be easier to move the selector lev-
er from position P. WARNING
Observe the safety warnings ›››
in Selector
lev er po
sitions on page 194.
● Never allow the brake to rub and do not use
the brake ped
al too often or for long periods.
Constant braking causes overheating in the
brakes. This could significantly reduce brak-
ing power, increase braking distance or even
result in the total failure of the brake system.
● To avoid rolling back on gradients always
hold the
vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If y

ou stop the vehicle on a gradient, do not
attempt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam- age the automatic gearbox. Apply the hand-
brak
e firm

ly or press the brake pedal in order
to prevent the vehicle from rolling back.
● If you allow the car to roll with the selector
lever in po
sition N with the engine switched
off, the automatic gearbox will be damaged as it will not be lubricated.
● In certain driving situations or traffic condi-
tions, suc
h as frequently starting, prolonged
“creeping” of the vehicle or traffic jams with
continuous stoppages, the gearbox could
overheat causing damage! If the warning
lamp  lights up, stop the vehicle as soon as
possible and wait for the gearbox to cool
››› page 200. Kick-down feature
The kick-down feature allows maximum ac-
c
el
er

ation to be reached.
When the accelerator pedal is pressed right
down past the point of resistance at full throt-
tle, the gearbox will shift down to a lower
gear, depending on road speed and engine
speed. The upshift to the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or w

et, the kick-down feature could cause the driving wheels to spin, which could
re
s

ult in skidding. Launch control program
3 Valid for vehicles: with Launch-Control/6-Speed
D SG w

ith diesel engines superior to 125 kW and pet-
rol engines superior to 140 kW.
The Launch control programme enables maxi-
mum acceleration.
Important: the engine must have reached op-
erating temperature and the steering wheel
must not be turned.
The engine speed for launch-control is differ-
ent on petrol and diesel engines. To use the
launch-control you must disconnect the anti-
slip regulation (ASR) through the Easy Con-
nect system menu ››› page 120. The warning
lamp  will stay switched on or will flash
slowly depending on whether or not the vehi-
cle has a driver information system*.
On vehicles with the driver information sys-
tem, the ESC lamp lights up permanently and
the corresponding text message Stability

traction control (ASR) 1)
.
– Turn the selector lever to the position “S”
or tiptronic, or else sel

ect the sport driv-
ing mode from the SEAT Drive Profile*
››› page 242.
– Press the brake pedal firmly with your left
foot and ho

ld it down for at least one sec-
ond.
– With your right foot, press the accelerator
down to the f

ull throttle or kick-down posi-
tion. The engine speed will stabilise at
about 3,200 rpm (petrol engine) or about
2,000 rpm (diesel engine).
– Take your left foot off the brake pedal. WARNING
● Alw a

ys adapt your driving style to the traf-
fic conditions.
● Only use the launch control programme
when roa
d and traffic conditions permit, and
make sure your manner of driving and accel-
erating the vehicle does not inconvenience or
endanger other road users.
● Make sure that the ESC remains switched
on. Plea
se note that when the ASR and ESC
are deactivated, the wheels may start to spin, causing the vehicle to lose grip. Risk of acci-
dent!
●
After putting the vehicle into gear, the
“spor t” mode of

the ESC should be deactiva-
ted again by briefly pressing the OFF but-
ton. Note
● Af ter u

sing the Launch control programme,
the temperature in the gearbox may have in-
creased considerably. In this case, the pro-
gramme could be disabled for several mi-
nutes. The programme can be used again af-
ter the cooling phase.
● Accelerating with the Launch control pro-
gramme pl
aces a heavy load on all parts of
the vehicle. This can result in increased wear
and tear. Downhill speed control*
The downhill speed control function helps
the driv
er when driv
in

g down steep gradi-
ents.
Downhill speed control is activated when the
selector lever is in D/S and the driver applies
the foot brake. The automatic gearbox auto-
matically engages a lower gear that is suita- ble for the slope. The downhill speed control
function att

empts to maintain the speed at
which the vehicle was travelling when the
foot brake was applied (subject to the laws of
physics and technical drive limitations). It
may be necessary to adjust the speed again
using the foot brake in certain situations. Giv-
en that the downhill speed control can only
change down to 3rd gear, on very steep de-
scents the tiptronic mode may be required. In
this case, manually reduce the tiptronic to
2nd or 1st gear to use the engine brake and
reduce the charge on the brakes.
Downhill speed control is deactivated as
soon as the road levels out again or you
press the accelerator pedal.
On vehicles with cruise control system*
››› page 212, downhill speed control is acti-
vated when you set a cruising speed. WARNING
The downhill speed control cannot defy the
la w

s of physics. Therefore, speed cannot be
maintained constant in all situations. Always
be prepared to use the brakes! 1)

Driving
Inertia mode The inertia mode enables the kinetic energy
of the
v
ehicle to be harnessed enabling cer-
tain stretches to be driven without using the
accelerator. This enables fuel to be saved.
Use the inertia mode to “let the vehicle roll”
before, for example, arriving in a town.
Switching on inertia mode
Important: selector lever must be in position
D, gradients below 12 %.
– Select, in SEAT Drive Profile*, Eco mode
›› ›

page 242.
– Take your foot off the accelerator.
The driver mes
sage Inertia will be dis-
played. At speeds higher than 20 km/h (12
mph), the gearbox will automatically disen-
gage and the vehicle will roll freely, without
the effect of the engine brake. While the vehi-
cle rolls, the engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To mak
e use of the braking force and switch
off the engine again, simply press the brake
pedal briefly.
Applying both the inertia mode (= prolonged
section with less energy) and the switching
off using inertia (= shorter section without the need for fuel) facilitates improved fuel
cons

umption and emission balance. WARNING
● If the iner ti

a mode has been switched on,
take into account, when approaching an ob-
stacle and releasing the accelerator pedal,
that the vehicle will not decelerate in the usu-
al manner: risk of accident!
● When using inertia mode while travelling
down hil
ls, the vehicle can increase speed:
risk of accident!
● If other users drive your vehicle, warn them
about inerti
a mode. Note
● Inerti a mode i

s only available in eco (SEAT
Drive Profile*) driving mode.
● The driver message Inertia is on
ly dis-
played with the current consumption. In iner-
tia mode the gear will no longer be displayed
(for example “E” will appear instead of “E7”).
● On downhill sections with gradients above
15 %, the inertia mode w
ill automatically be
switched off temporarily. Emergency program
A backup programme is in place if a fault
shou
l
d oc

cur in the control system. If all the positions of the selector lever are
shown ov

er a light background on the instru-
ment panel display, there is a system fault
and the automatic gearbox will operate in
with the backup programme. When the back-
up programme is activated, it is possible to
drive the vehicle, however, at low speeds and
within a selected range of gears. In some ca-
ses driving in reverse gear may not be possi-
ble. CAUTION
If the gearbox operates with the backup pro-
gramme, t ak

e the vehicle to a specialised
workshop and have the fault repaired without

Driving
Run-in and economical driving R u
nnin
g in the engine A new vehicle should be run in over a dis-
tanc
e of

1500 km (1000 miles). For the first
1,000 km the engine speed should not ex-
ceed 2/3 of the maximum permissible engine
speed. In doing so, do not accelerate at full
throttle and do not drive with a trailer! From
1000 to 1500 km (600 to 1000 miles) you
can gradually increase the engine rpm and
road speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on when all the moving parts have bed-
ded down.
How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Subsequently, also drive at a moderate
rate, especially when the engine is still cold:
this will lead to less engine wear and tear
and will prolong its useful life.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs “smoothly”.
If the engine revs too much, cut fuel injection
to protect the engine. Environmental compatibility Environmental protection is a top priority in
the des
ign, c

hoice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage recy-
cling
● Joints and connections designed for easy

Choice of materials
● Use of recycled materials.
● Use of compatible plastics in the same part
if its c
omponents are not easily separated.
● Use of recycled materials and/or materials
originating fr
om renewable sources.
● Reduction of volatile components, includ-
ing odour, in p
lastic materials.
● Use of CFC-free coolants.

Operation
Active cylinder management (ACT ®
)*
D ependin
g on
vehicle equipment, the active
cylinder management (ACT ®
) may automati-
cally deactivate some of the engine cylinders
if the driving situation does not require too
much power. When it is switched off, no fuel
is injected into these cylinders, hence total
fuel consumption may be reduced. The num-
ber of active cylinders can be seen on the in-
strument panel display ›››
 page 37.
Foresight when driving
Acceleration causes the vehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic
lights are red). This takes advantage of the
engine braking effect, reducing wear on the
brakes and tyres. Emissions and fuel con-
sumption will drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear. Running the engine at
high rpm in the lower gears uses an unneces-
sary amount of fuel.
Manual gearbox : shift up from first to second
gear as soon as possible. In any case, we rec-
ommend that you change to a higher gear
upon reaching 2,000 rpm. Choosing the right gear enables fuel savings. Select the highest
poss
ible gear appropriate for the driving sit-
uation (the engine should continue function-
ing with cyclical regularity).
Automatic gearbox : accelerate gradually and
without reaching the “kick-down” position.
Avoid driving at high speed
Avoid travelling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling
is automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting the engine. Avoid running the engine at high
speed.
Re
gular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature in
order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 308 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
202

Driving
Avoid carrying unnecessary loads
Giv en th
at
every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off
any unneeded electrical devices. Devices that
use a lot of electricity includes the blower at
a high setting, the rear window heating or
the seat heating*.
Power management
This sy
stem helps to ensure reliable
starting The power management controls the distribu-
tion of
el
ectric

al energy and thus helps to en-
sure that there is always enough power avail-
able to start the engine. If a vehicle with a conventional electrical sys-
tem is

left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of
the battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynamic
power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sen-
sors detect the battery voltage, battery cur-
rent and battery temperature. This enables
the system to calculate the current power lev-
el and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is switched off. The system takes the battery di-
agnosi
s data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
● Neither is the po

wer management system
able to overcome the given physical limits.
Please remember that the power and useful
life of the battery are limited.
