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

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.

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. 

Tyre monitoring systems Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Caring for and cleaning the vehicle exterior ⇒ page 198
● Wheels and tyres ⇒ page 223
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre
pressure losses, to tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. Tyre pressure that is too low could cause overheat-
ing, resulting in tread detachment or even burst tyres.
● Tyre pressure should be that indicated on the label when the tyres are
cold at all times ⇒ page 266.
● Regularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
● Regularly check your tyres for damage and wear.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 

176Driver assistance systems
Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while the function is verified. They will switch off after a
few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may the damaged resulting in a loss of control of the
vehicle and a serious or fatal accident.
● If the warning lamp  lights up, stop immediately and check the
tyres.
● If the tyres are inflated at different pressures or if a tyre pressure is
too low, this will increase tyre wear, negatively affecting vehicle stability
and increasing braking distances.
● If tyres are inflated at different pressures or a tyre pressure is too low,
a tyre may be damaged and burst resulting in a loss of control of the ve-
hicle.
● The driver is responsible for ensuring that all of the vehicle tyres are
correctly inflated to the right pressure. The recommended tyre pressure
is indicated on the label ⇒ page 266.
● The tyre monitoring system can only operate correctly if all of the
tyres are inflated to the correct pressure when cold.
● Driving with tyres at the wrong pressure can cause them damage and
result in an accident. Ensure that the tyre pressures of all the tyres corre-
spond to the vehicle load.
● Before starting a journey, always inflate tyres to the correct pressure.
● Tyres with insufficient pressure are subjected to more flexing. Due to
this, the tyre could become excessively hot, causing tread separation
and also tyre blow-out.
● With an overloaded vehicle at high speed, the tyres can overheat and
burst resulting in a loss of vehicle control.
WARNING (Continued)
● Tyre pressures which are too high or too low reduce the useful life of
the tyre, affecting vehicle performance.
● If a tyre has not been punctured then it does not have to be changed
immediately; drive to the nearest specialised workshop at a moderate
speed and have the tyre checked and inflated to the correct pressure.
WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.
Note
● If excessively low tyre pressure is detected with the ignition on, an audi-
ble warning will sound. In the event that there is a fault in the system, an
audible warning will sound.
● Driving on dirt tracks for a long period of time or driving in a sporty style
can temporarily deactivate the TPMS. The control lamp shows a fault, but
disappears when road conditions or the driving style change. 

178Driver assistance systems
Parking aid
General information
Various systems are available to help you when parking or manoeuvring in
tight spaces, depending on the equipment fitted on your vehicle.
The rear parking aid is an audible assistant that warns about obstacles lo-
cated behind the vehicle ⇒ page 179.
During parking, the plus parking aid assists you visually and audibly about
obstacles detected in front and behind the vehicle ⇒ page 179.
WARNING
● Always pay attention (also when looking straight ahead) to traffic and
the vehicle surroundings. The assistance systems are not a replacement
for driver awareness. When inserting or removing the vehicle from a park-
ing space, or when performing similar manoeuvres the driver always as-
sumes the responsibility.
● Take into account that the system is not always in conditions to rec-
ognise or represent certain surfaces, such as dress fabric: Risk of causing
an accident!
● The sensors and cameras have blind spots, making the detection of
people and objects impossible. Pay special attention to children and ani-
mals: Risk of causing an accident!
● Always keep visual control of the vehicle surroundings: use the rear
vision mirrors for additional help.
CAUTION
● Under certain circumstances, the system does not detect or display cer-
tain objects:
–Objects such as snow chains, trailer draw bars, bars or fences
– Objects that are located above the sensors, such as protrusions in a
wall.
– Objects with certain surfaces or structures, such as wire mesh fences
or powder snow.
● When the vehicle approaches a low obstacle, it could disappear from
the angle of measurement. In this case, take into account that the system
will no longer warn about this obstacle.
● The knocks or damage on the radiator grille, bumper, wheel arch and ve-
hicle underbody can adjust the orientation of the sensors. This can affect
the parking aid function. Have the function checked by a specialised work-
shop.
Note
● In certain situations, the system can give a warning even though there is
no obstacle in the detected area, e.g:
–for roads with certain surfaces, or with long grass
– for external ultrasound sources, such as cleaning vehicles
– In downpours, intense snow or dense exhaust gases
● In order to familiarise yourself with the system, it is advised that you
practice parking in an area or car park that is free from traffic. There must be
good weather and light conditions.
● The volume and tone of the warnings can be modified, in addition to the
indications ⇒ page 181.
● In vehicles without a driver information system, these parameters can be
modified in a SEAT Official Service or in a specialised workshop.
● Please observe information on towing a trailer ⇒  page 182.

Driver assistance systems
● The display on the Easy Connect screen shows a slight time delay.
● To ensure that the parking aid works properly, the sensors must be kept
clean and free of ice and snow. 
Rear parking aid*
The rear parking aid is an audible assistant. Description
There are sensors integrated in the rear bumper. When the sensors detect
an obstacle, you are alerted by audible warnings.
Make sure that the sensors are not covered by adhesives, residues and the
like, given that this could affect the system operation. Cleaning instructions
⇒ page 199.
The approximate measurement range of the sensors is:
rearside0.90 mcentre1.60 m
As you approach the obstacle, the time interval between the audible warn-
ings will be reduced. When you reach around 0.30 m the warning will be
constant: Do not continue to move forward (or backward) ⇒ 
in General
information on page 178, ⇒  in General information on page 178 !
If you maintain separation from the obstacle, the volume of the warning be-
gins to reduce after four seconds (does not affect the tone of the constant
warning).
Activate
When engaging reverse gear, the parking aid is automatically switched on.
This is confirmed with a short warning. Plus parking aid*

184Intelligent technology
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
