Automatic gearbox/DSG automatic gearbox*
Introduction
Your vehicle is equipped with an electronically controlled manual gearbox.
Torque between the engine and the gearbox is transmitted via two inde-
pendent clutches. They replace the torque converter found on conventional
automatic gearboxes and allow for smooth, uninterrupted acceleration of
the vehicle.
The tiptronic system allows the driver to change gears manually if desired
⇒ page 159, Changing gears in tiptronic mode*. 
Selector lever positions
The selector lever position engaged is highlighted on the display in the in-
strument cluster. 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 me-
chanically. The parking lock must be engaged only when the vehicle is sta-
tionary ⇒ 
.
The interlock button (the button on the selector lever handle) must be
pressed in and simultaneously the brake pedal must be depressed before
moving the selector lever either 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 interlock button must be press-
ed in and at the same time the brake pedal must be depressed. 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 lever again will select normal mode (D). The
selected driving mode is shown on the instrument panel display.
In normal mode
(D), the gearbox automatically 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 accelerating the
gear shifts will be noticeable.
The brake pedal must be pressed when moving the selector lever from D/S
to N if the vehicle is stationary or at speeds below 5 km/h (3 mph) ⇒ 
.
Under certain circumstances (e.g. when driving in mountains) it can be ad-
vantageous to switch temporarily to tiptronic mode ⇒ page 159, in order to
manually select gear ratios to suit the driving conditions.
WARNING
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(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. Failure to do so
could result in an accident. 

Fig. 99 In the wind-
screen: Field of vision of
the Lane Assist system
camera
Using the camera located in the windscreen, the Lane Assist system detects
the possible lines dividing the lanes. When the vehicle involuntarily ap-
proaches a dividing line it has detected, the system notifies the driver with
a corrective steering movement . The corrective steering movement can be
overruled at any moment.
No warning is produced with the turn signals activated, given that the Lane
Assist system understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in the steering wheel and require
the driver to take active control of driving:
● When the limits of the very nature of the system are reached.
● When the maximum rotational torque during the corrective steering
movement is not enough to keep the vehicle inside the lane.
● When no lane is detected during the corrective steering movement. 

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.

Multi-collision brake
In an accident, the multi-collision brake can help the driver by braking to
avoid the risk of skidding during the accident, which could lead to further
collisions.
The multi-collision brake works for front, side or rear accidents, when the
airbag control unit records its activation level and the accident takes place
at a speed of over 10 km/h (6 mph). The EI ESC automatically brakes the
vehicle, as long as the accident has not damaged the ESC, the brake hy-
draulics or the on-board network.
The following actions control automatic braking during the accident:
● When the driver presses the accelerator. The automatic braking does not
take place.
● When the braking pressure through pressing the brake pedal is greater
than the system’s braking pressure. The vehicle will brake manually.
● Multi-collision braking will not be available if ESC is malfunctioning.
WARNING
● Nor can the ESC, ABS, ASR, EDL, electronic self-locking differential or
selective torque control systems exceed the limits imposed by the laws
of physics. Always bear this in mind, especially on wet or slippery roads.
If you notice the systems cutting in, you should reduce your speed imme-
diately to suit the road and traffic conditions. Do not be encouraged to
take risks by the presence of more safety systems. If you do, an accident
may occur.
● Please remember that the accident risk always increases if you drive
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. The ESC, ABS, brake assist, EDL, elec-
tronic self-locking and selective torque control systems cannot prevent
accidents: risk of accidents!
● Accelerate with caution on slippery surfaces (for example, icy or
snow-covered). Despite the control systems, the driven wheels could
spin, affecting the stability of the vehicle: risk of accident!
Note
● The ABS and ASR will only operate correctly if the four wheels have iden-
tical tyres. Any differences in the rolling radius of the tyres can cause the
system to reduce engine power when this is not desired.
● The regulating processes of the systems can make noises when they in-
tervene.
● If the warning lamp  lights up, or  alternatively, there could be a
fault ⇒ page 69. 
Switching on/off the ESC and ASR
The ESC is switched on automatically when the engine is
started. The ESC cannot be deactivated. ESC in "Sport" mode
Sport mode is activated through the Easy Connect system ⇒ page 79 menu.
The ability of the ESC to stabilise the vehicle is limited; the traction control
system (ASR) becomes disabled ⇒ 
.
The control lamp  will light up. For vehicles with a driver information sys-
tem*, the driver will be shown the electronic stability control (ESC) option:
sport. Warning! Limited stability .
In the following exceptional circumstances enabling the ESC Sport mode to
improve the traction of the wheels is tenable:
● when rocking the vehicle backwards and forwards to free it.
● Driving in deep snow or on loose surfaces.
Disable ESC Sport mode
Through the Easy Connect system ⇒ page 79. The warning lamp  will

Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed ⇒ 
.
Fault in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest
specialised workshop and have the fault repaired. Drive there slowly and re-
member that you will have to apply more pressure on the brake pedal and
allow for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too
low. The brake fluid level is monitored electronically.
Brake servo
The brake servo increases the pressure you apply to the brake pedal. It
works only when the engine is running.
WARNING
● Apply the brakes heavily to clean the brake system only in a suitable
traffic situation. Do not put other road users in danger: risk of causing an
accident.
● Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
CAUTION
● Never let the brakes “drag” by leaving your foot on the pedal when it is
not necessary to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.
● Before driving down a long, steep gradient, it is advisable to reduce
speed and select a lower gear. This makes use of engine braking and re-
lieves the brakes. If you still have to use the brakes, it is better to brake
firmly at intervals than to apply the brakes continuously.
Note
● If the brake servo is out of action due to a malfunction, or if the car has
to be towed, you will have to press the brake pedal considerably harder to
make up for the lack of servo assistance.
● If you wish to equip the vehicle with accessories such as a front spoiler
or wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat. 
Electro-mechanical steering
Electro-mechanical power steering assists the driver when
steering.
Electro-mechanical power steering adapts electronically to the speed of the
car, torque and turning angle.
If the power steering should fail at any time or the engine is switched off (for
instance when being towed), the car can still be steered. However, more ef-
fort than normal will be required to turn the steering wheel.

Fitting a towing bracket
● Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact a Technical Service to check
whether your cooling system needs modification.
● The legal requirements in your country must be observed (e.g. the fitting
of a separate control lamp).
● Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle electri-
cal system. This requires specialised knowledge and tools.
● Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.
WARNING
The towing brackets should be fitted at a specialised workshop.
● If the towing bracket is incorrectly installed, there is a serious danger
of accident.
● For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.
CAUTION
● If the power socket is incorrectly installed, this could cause damage to
the vehicle electrical system. 

Checking and refilling levels
Brake fluid
Fig. 111 Engine com-
partment: brake fluid res-
ervoir, lid
Checking the brake fluid level
The brake fluid level must be between the MIN and MAX markings.
However, if the brake fluid level goes down noticeably in a short time, or
drops below the MIN mark, there may be a leak in the brake system. Seek
specialist assistance. A warning light on the instrument panel display moni-
tors the brake fluid level ⇒ page 69.
In right-hand drive vehicles the brake fluid reservoir is on the other side of
the engine compartment.
Changing brake fluid
The regular intervals at which the brake fluid should be replaced are listed
in the Service Plan. We recommend you have the brake fluid replaced at a
SEAT Official Service, during an Inspection Service.
WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicles functions are "lost" ( ⇒ table
on page 218). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered. 
