CAUTION
● If you stop the vehicle on a gradient, do not attempt to stop it from roll-
ing by depressing the accelerator when a gear has been selected. This
could cause overheating and damage the automatic gearbox. Apply the
handbrake 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 position N with the
engine switched off, the automatic gearbox will be damaged as it will not be
lubricated.
● In certain driving situations or traffic conditions, such as frequently
starting, prolonged creeping of the vehicle, or traffic jams with continuous
stoppages, the automatic 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 162.

Downhill speed control*
The downhill speed control function helps the driver when
driving down steep gradients.
Downhill speed control is activated when the selector lever is in D/S and
the driver applies the foot brake. The automatic gearbox automatically en-
gages a lower gear that is suitable 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 techni-
cal drive limitations). It may be necessary to adjust the speed again using
the foot brake in certain situations. Given that the downhill speed control
can only change down to 3rd gear, on very steep descents 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 164, downhill speed con-
trol is activated when you set a cruising speed.
WARNING
The downhill speed control cannot defy the laws of physics. Therefore,
speed cannot be maintained constant in all situations. Always be pre-
pared to use the brakes!

Changing gear manually with the selector lever
It is possible to change to tiptronic mode, both when the vehicle is
stopped and while driving. –
To switch to tiptronic mode, move the selector lever from posi-
tion D/S to the right. As soon as the change is made, the selec-
tor lever will be shown in the position G (i.e. G4 means that 4th
gear is engaged) on the instrument panel display.
– Move the selector lever forwards +
to select a higher gear
⇒ Fig. 91.
– Move the selector lever backwards -
to select a lower 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 G.
– Press the gearshift paddle +
to select a higher gear
⇒ Fig. 92.
– Press the gearshift paddle -
to select a lower gear.
– With the selector lever in position D/S, if no paddle is operated
during a short period of time, the gearbox control system
switches back to automatic mode. To switch to permanent man-
ual gear change using the gearshift paddles, move the selector
lever from position D/S to the right.
When accelerating, the gearbox automatically shifts up into the next gear
shortly before the maximum engine speed is reached.
If you select a lower gear, the automatic gearbox 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, depending on road speed and engine speed. 

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

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. 

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.

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.

Description
Depending on the equipment fitted in the vehicle, SEAT Drive Mode can op-
erate on the following functions:
Engine
Depending on the profile selected, the engine responds more spontaneous-
ly or more in harmony with the movements of the accelerator. Additionally,
when eco mode is selected, the Start-stop function is automatically activa-
ted.
In vehicles with DQ transmission, the gear change points are modified to
position them in lower engine speed ranges ( eco) or higher (sport). Addi-
tionally, eco mode activates the Inertia function, enabling the consumption
to be further reduced.
In manual vehicles, eco mode causes the gear recommendation indications
that appear on the instrument panel to vary, facilitating more efficient driv-
ing.
Steering
Power steering becomes more robust in sport mode to enable a more sporty
driving style.
Air conditioning
In vehicles with Climatronic, this can operate in eco mode, especially re-
stricting fuel consumption.
Ambient lighting
The ambient lighting guides located in the interior front door panels of the
Leon FR change colour from white to red when sport mode is activated. Setting driving mode
You can select from Normal, Sport, Eco and Individual.

Electronic Stability Control (ESC)
Description
EI ESC helps to improve safety. It reduces the tendency to skid and improves
the stability and roadholding of the vehicle. EI ESC detects critical handling
situations, such as vehicle understeer or oversteer, or wheelspin on the
driving wheels. It stabilises the vehicle by braking individual wheels or by
reducing the engine torque. The warning lamp will flash on the instrument
panel when the ESC is intervening .
ESC includes the Anti-lock brake system (ABS), the brake assist system, the
traction control system (ASR), electronic differential lock (EDL), electronic
self-locking*, selective torque control* and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking until the vehicle
has reached a virtual standstill. You can continue to steer the vehicle even
when the brakes are on full. Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal pulsate while the ABS is
working.
Brake assist system
The brake assist system can reduce the required braking distance. The brak-
ing force is automatically boosted if you press the brake pedal quickly in an
emergency. You must keep pressing the brake pedal until the danger has
passed. Traction control system (ASR)
In the event of wheelspin, the traction control system reduces the engine
torque to match the amount of grip available. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the spinning wheel and directs
the power to the other driven wheel. This function is available up to a speed
of around 100 km/h, 62 mph).
To prevent the disc brake of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle can still
be driven. The EDL will switch on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control the following: Tractor-trailers
tend to sway. When the swaying of the trailer is felt by the vehicle and de-
tected by the ESC, it will automatically brake the towing vehicle within the
limits of the system and mitigate the sway. Tractor-trailer sway mitigation is
not available in all countries.
Electronic self-locking*/Selective torque control*
When driving around bends, an electronic self-locking intervenes. The front
wheel on the inside of the curve, or the two inside wheels, respectively, are
selectively braked as required. This minimises the traction of the front
wheels, allowing you to take bends with greater precision and neutrality. In
certain circumstances, where roads are wet or snow-covered, the respective
system may not intervene.
