Kick-down feature
The kick-down feature allows maximum acceleration to be
reached.
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will shift down to a lower gear, depending
on road speed and engine speed. The upshift to the next higher gear is de-
layed until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.

Launch Control Programme 1)
The Launch control programme enables maximum accelera-
tion.
Important: the engine must have reached operating temperature
and the steering wheel must not be turned.
The engine speed for Launch control is different on petrol and die-
sel engines. Before you can use the Launch control, you must first switch off the traction control system (ASR), either using the Easy
Connect system
⇒ page 79, or with the switch 
OFF
; the warning
lamp  will stay on or will flash slowly depending on whether the
vehicle has a driver information system* 2)
.
– When the engine is running, switch off the traction control
(ASR) 2)
3)
.
– Move the selector lever to position “S” or tiptronic, or select the
driving mode Sport from the SEAT Drive Mode* ⇒  page 171.
– Press the brake pedal firmly with your left foot and hold it down
for at least one second.
– With your right foot, press the accelerator down to the full throt-
tle or kick-down position. The engine speed will stabilise at ap-
prox. 3200 rpm (petrol engine) or approx. 2000 rpm (diesel en-
gine).
– Take your left foot off the brake pedal. 
1)
Valid for vehicles: with Launch Control/6-Speed DSG with diesel engines superior to 125
kW and petrol engines superior to 140 kW.
2) On vehicles with the driver information system, the ESP lamp lights up permanently and
the corresponding text message Stability control deactivated (temporary) appears on the in-
strument panel to indicate the deactivation status.
3) Vehicles without driver information system: the warning lamp flashes slowly/Vehicles with
driver information system: the warning lamp stays on.

Driving
WARNING
● Always adapt your driving style to the traffic conditions.
● Only use the Launch control programme when road and traffic condi-
tions permit, and make sure your manner of driving and accelerating the
vehicle does not inconvenience or endanger other road users.
● Make sure that the ESC remains switched on. Please note that when
the ASR and ESC are deactivated, the wheels may start to spin, causing
the vehicle to lose grip. Risk of accident!
● After engaging gear, the Sport mode of the ESC should be deactivated
again by briefly pressing the 
OFF
button.
Note
● After using the Launch control programme, the temperature in the gear-
box may have increased considerably. In this case, the programme could be
disabled for several minutes. The programme can be used again after the
cooling phase.
● Accelerating with the Launch control programme places a heavy load on
all parts of the vehicle. This can result in increased wear and tear. 
Inertia mode
The inertia mode enables the kinetic energy of the vehicle to be
harnessed enabling certain stretches to be driven without using
the accelerator. This enables fuel to be saved. Use the inertia mode
to let the vehicle roll in advance of, for example, arriving in a town.
Switching on inertia mode
Important: selector lever must be in position D, gradients below
12 %. –
Select Eco mode ⇒  page 171 once in SEAT Drive Mode*.
– Take your foot off the accelerator.
The driver message Inertia will be displayed. At speeds higher
than 20 km/h (12 mph), the gearbox will automatically disengage
and the vehicle will roll freely, without the effect of the engine
brake. While the vehicle rolls, the engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To make 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 inertia mode has been switched on, take into account, when ap-
proaching an obstacle and releasing the accelerator pedal, that the vehi-
cle will not decelerate in the usual manner: risk of accident!
● When using inertia mode while travelling down hills, the vehicle can
increase speed: risk of accident!
● If other users drive your vehicle, warn them about inertia mode. 

162Driving
Note
● Inertia mode is only available in eco driving mode (SEAT Drive Mode*).
● The driver message Inertia is only displayed with the current consump-
tion. In inertia mode the gear will no longer be displayed (for example: E will
appear in place of E7).
● On downhill sections with gradients above 15 %, the inertia mode will
automatically be switched off temporarily. 
Backup programme
A backup programme is in place if a fault should occur in the
control system.
If all the positions of the selector lever are shown over a light background
on the instrument panel display, there is a system fault and the automatic
gearbox will operate in with the backup programme. When the backup pro-
gramme is activated, it is possible to drive the vehicle, however, at low
speeds and within a selected range of gears. In some cases driving in re-
verse gear may not be possible .
CAUTION
If the gearbox operates with the backup programme, take the vehicle to a
specialised workshop and have the fault repaired without delay. 
Clutch
 Clutch overheated! Stop the vehicle!
The clutch has overheated and could be damaged. In order to prevent the
temperature from increasing again and so that the clutch is cooled, stop the
vehicle and wait for the gearbox to cool down with the selector lever in posi- tion P and the engine running at idling speed. If the warning does not
switch off, do not continue driving. Seek specialist assistance. Failure to do
so could cause considerable damage to the gearbox. When the warning
switches off, the fault should be corrected by a specialised workshop with-
out delay.

message will be displayed when the gearbox has cooled again. 
Manual release of the selector lever
The selector lever can be released manually if the electrical
power supply should fail.
Fig. 93 Selector lever:
manual release from po-
sition P
The manual release mechanism is located under the selector lever
console on the right side. Releasing the selector lever requires a
certain degree of practical skill. We therefore advise you to obtain
professional assistance. A screwdriver will be needed to carry out the manual release. Use
the flat part of the screwdriver blade
⇒ page 232.
Removing the cover from the selector lever
– Apply the handbrake  ⇒ 
to ensure that the car does not
move.
– Carefully pull the corners of the selector lever boot and fold up
the selector lever boot (inside out) by hand.
Releasing the selector lever
– Using a screwdriver, press and hold the yellow unlocking tab
sideways ⇒ Fig. 93.
– Now press the interlock button on the selector lever A
and
move the selector lever to position N.
– After carrying out the manual release, attach the selector lever
boot on the gearbox console again.
If the power supply should ever fail (discharged battery, etc.) and the vehi-
cle has to be pushed or towed, the selector lever must first be moved to po-
sition N. This is possible after operating the manual release mechanism.
WARNING
The selector lever may be moved out of position P only when the hand-
brake is firmly applied. If this does not work, secure the vehicle with the
brake pedal. On a slope the vehicle could otherwise start to move inad-
vertently after shifting the selector lever out of position P - accident risk!

Cruise control system (CCS)*
Introduction
The cruise control system (CCS) is able to maintain the set speed from 20
km/h (15 mph).
A constant speed is maintained using the engine power control or by apply-
ing the active brake ⇒ 
.
Additional information and warnings:
● Change gear ⇒ page 154.
● Accessories and technical modifications ⇒ page 230.
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the cruise control in heavy traffic, if the distance from the
vehicle in front is insufficient, on steep roads, with several bends or in
slippery circumstances (snow, ice, rain or loose gravel), or on flooded
roads.
● Never use the CCS when driving off-road or on unpaved roads.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
WARNING (Continued)
● It is dangerous to use a set speed which is too high for the prevailing
road, traffic or weather conditions.
● When travelling down hills, the CCS cannot maintain a constant
speed. The vehicle tends to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the vehicle.

Lane Assist system* Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
The intelligent technology in the Lane Assist system cannot change the
limits imposed by the laws of physics and by the very nature of the sys-
tem. Careless or uncontrolled use of the Lane Assist system may cause
accidents and injury. The system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● Always keep your hands on the steering wheel so it can be turned at
any time.
● The Lane Assist system does not detect all road markings. The road
surfaces, road structures or objects in poor condition can be incorrectly
detected as road markings under certain circumstances by the Lane As-
sist system. In such situations, switch the Lane Assist system off imme-
diately.
● Please observe the indications on the instrument panel and act as is
necessary.
● Always pay attention to the vehicle's surroundings.
● When the area of vision of the camera becomes dirty, covered or is
damaged, the Lane Assist system function can be affected.
CAUTION
In order to avoid influencing the operation of the system, the following
points must be taken into account:
● Regularly clean the area of vision of the camera and keep it in a clean
state, without snow or ice.
● Do not cover the area of vision of the camera.
● Check that the area of vision of the windscreen camera is not damaged. 
