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

s

the vehicle moves. The engine can only start with the selector
lever in po

sition 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 188, 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

Driving down hills: in some situations (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. »

Operation
WARNING
Observe the safety warnings ››› in Selector
lev er po
sitions on page 189.
● 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-
brake firmly 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 194. Kick-down feature
The kick-down feature allows maximum ac-
cel
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
result in skidding. Launch control program

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 122. 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

or tiptronic, or else select the sport driv-
ing mode from the SEAT Drive Profile*
››› page 229.
– 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 moving off, the ESC “sport” mode
should be de
activated by briefly pressing the
  button. Note
● Aft er 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 attempts 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 c

harge 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 205, 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! 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

Operation
The driver message Inertia wi
l l 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
consumption 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

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

p

articulate filter
The exhaust system manager detects that the
diesel particulate filter is nearly saturated
and contributes to self-cleaning by recom-
mending the optimal gear. For this reason, it
might be necessary to drive for a short time
at a high rpm. WARNING
The gear change indicator is only an auxiliary
fu nction and in no c

ase should be a substi-
tute for careful driving.
● The responsibility of choosing the correct
gear dependin
g on the situation (e.g. over-
taking, driving up or down a slope or towing a
trailer) lies with the driver. For the sake of the environment
Selecting the correct gear can help to save
fuel . Note
The recommended gear indication turns off
when the clut c

h pedal is pressed in vehicles
with manual gearbox or when the selector
lever is removed from the tiptronic position in
vehicles with an automatic gearbox. Steering
Intr oduction The power steering is not hydraulic but elec-
tr
omec
h

anical. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running. »

Electromechanical steering
In vehicles with electromechanical steering,

Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, help s

the driver to control vehicle steer-

R u
nnin

g in a new engine The engine needs to be run-in over the first
1500 km (900 mil
e

s).
For the first 1,000 kilometres (600 miles)
– Do not drive at speeds of more than 2/3
the maximum s

peed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1,000 k i

lometres (600 miles) to 1,500
kilometres (900 miles)
– Speeds can be gradual
ly increased to the
maximum road speed or maximum permis-
sible engine speed (rpm).
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 in. For the sake of the environment
If the engine is run in gently, its life will be in-
cr e

ased and its oil consumption reduced. Running in tyres and brake pads
New tyres should be run in carefully for the
firs
t

500 km (300 miles) and new brake pads
should be run in carefully for the first 200 km
(125 miles).
During the first 200 km (125 miles) you have
to compensate for the reduced braking effect
by applying more pressure to the brake ped-
al. In case of a sharp braking, the braking
distance will be longer with new brake pads
than with brake pads which have been run-
in. WARNING
● At fir s

t, new tyres do not give maximum
grip, and require running-in. This may cause
an accident. Drive particularly carefully in the
first 500 km (300 miles).
● New brake pads must be “run in” and do
not hav
e the correct friction properties during
the first 200 km (125 miles). However, the re-
duced braking capacity may be compensated
by pressing on the brake pedal a little harder. Environmental compatibility

g Fuel consumption, environmental pollution
and w
e
ar t

o the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Active cylinder management (ACT ®
)*
Depending 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 p

anel display. ›››
 page 38.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, you have to
brake less often and, thus, accelerate less. If
it is possible, let the vehicle roll with a gear
engaged, for example, if you see a red light
ahead. The braking effect achieved in this
way helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
Change gear early to save energy
An effective way of saving fuel is to change
up quickly through the gears. Running the
engine at high rpm in the lower gears uses
an unnecessary amount of fuel.
Manual gearbox: shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel ››› page 195.
Avoid driving at high speed
We advise you not to drive at the top speed
permitted by the vehicle. Fuel consumption,
198

Driving
exhaust emissions and noise levels all in-
c r
e
ase very rapidly at higher speeds. Driving
at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine
when waiting in a traffic jam, at level cross-
ings or at traffic lights with a long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re-
start the engine.
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.
Periodic maintenance
Periodic maintenance work guarantees that,
before beginning a journey, you will not con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary. Avoid short journeys
To reduc
e the consumption and emission of
polluting exhaust gases, the engine and the
exhaust gas filtration systems should reach
the optimum operating temperature.
With the engine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom-
mend avoiding short trips whenever possi-
ble.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
wear and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that 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. A roof rack is often left in place for the sake
of con
venience, even when it is no longer
needed. At a speed of 100 km/h (62 mph)
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
blower at high speeds, the rear window heat-
ing or the seat heaters*. Note
● If y

our vehicle has Start-Stop, it is not rec-
ommended that you switch this function off.
● It is recommended that you close
the win-
dows when driving at more than 60 km/h
(37 mph).
● Do not drive with your foot resting on the
clutc
h pedal,, as the pressure can make the
plate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the car on a hill with the clutch,
use the foot
brake or hand brake, using the
latter to start. The fuel consumption will be » 199

Introduction WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the ar
ea of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  re-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
To maintain the useful life of the catalytic
con
v

erter
– Use only unleaded petrol with petrol en-
gines, as

lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too muc

h engine oil ››› page 277, Top-
ping up engine oil.
– Never tow the vehicle to start it, use jump
lea

ds if necessary ›››
 page 71.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 121. If this hap-
pens, unburnt fuel can enter the exhaust sys-
tem and escape into the environment. The
catalytic converter can also be damaged by
overheating. CAUTION
Never run the fuel tank completely dry be-
cau se the irr

egularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
work in

g perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel particulate filter
3 App
lies to vehicles with diesel engine
The die
sel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the
