WARNING
● Never ru n the en
gine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extr eme lo

ad conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
shoul d driv

e off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it i

s difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both side s
to release the steering lock.
● When starting from cold, the engine may be
a little noisy
for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
reconnect
ed, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehic

les with automatic gearbox: after
switc
hing off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
lect
or l

ever is locked. Switching off the engine with the key

ossible vehicle theft is prevented with the
steering lock engaged. WARNING
● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury. ●
Never r emo

ve the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leav
e the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
loa d f

or a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● Aft er the en

gine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation.
● If the vehicle is stopped and the Start-Stop
syst
em* switches off the engine, the ignition » 165

Driving
● Sec ur
e the
vehicle as usual by applying the
handbrake firmly and putting it in 1st gear. WARNING
● Tak e me

asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They cou
ld set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever.
● Depending on weather conditions, it may
become extr
emely hot or cold inside the vehi-

t to move as soon as a gear is engaged
and the clutch released. This is also the case
with the electro-mechanical parking brake
switched on.
● Never engage reverse gear when the vehi-
cle i

If the gear is changed down inappropriately
by sel

ecting a gear that is too low, you may
lose control of the vehicle, causing an acci-
dent and serious injuries. CAUTION
When travelling at high speeds or at high en-
gine speed s, sel

ecting a gear that is too low can cause considerable damage to the clutch

, please observe the following:
● Do not rest your hand on the gear lever
while driv
ing. The pressure applied by your
hand is transmitted to the gearbox selector
forks.
● Always ensure that the vehicle is complete-
ly st
opped before engaging the reverse gear.

 page 44
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
Rever

se gear must be engaged only when the
vehicle is stationary and the engine is idling
››› .
T o mo
v

e the selector lever to position R, the
interlock 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. The brake pedal must be pressed when mov-
ing the select

or lever from D/S to N if the ve-
hicle is stationary or at speeds below 5 km/h
(3 mph) ››› .
Under c er
t

ain circumstances (e.g. when driv-
ing in mountains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 170, 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.

Operation
Note
● If the sel ect
or lever lock does not engage,
there is a fault. The transmission is interrup-
ted to prevent the vehicle from accidentally
moving. Follow the procedure below in order
for the selector lever lock to engage again:
–With a 6-speed gearbox: press the brake
pedal and release it again.
– With a 7-speed gearbox: press the brake
pedal. Move the selector lever to posi-
tion P or N and subsequently engage a
gear.
● Despite a gear being engaged, the vehicle
does not
move forwards or back. Proceed to
the next mode:
– When the vehicle does not move in the
required 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 direction, there is a system mal-
function. Seek specialist assistance and
have the system checked. Changing gears in tiptronic mode*

Driving
When accelerating, the gearbox automatical-
ly shif
ts
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
overrevving 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.

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-

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

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 programme

● 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
“sport” mode of
the ESC should be deactiva-
ted again by briefly pressing the OFF but-
ton. 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 driver 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 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 185, 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 prep
ar

ed 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

– 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

Operation
Applying both the iner ti
a 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

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-

Run-in and economical driving Runnin
g-in the engine A new vehicle should be run in over a dis-
t
anc
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.

Operation
Exhaust gas filtration systems Catalytic converter
App
lie
s to vehicles with petrol engine: the
vehicle must only be used with unleaded pet-
rol, otherwise the catalytic converter will be
irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: the
diesel 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 in 4th or 5th gear (auto- matic gearbox: gear S). Maintain the engine
speed at
ap

proximately 2,000 rpm. The rise
