Operation
 ACC: parking brake applied
The A C
C is deactivated if the parking brake is
applied. The ACC is available once again after
the parking brake is released.
 ACC: currently not available.
Intervention of stability con-
trol
The message for the driver is displayed when
the electronic stability control (ESC) inter-
venes. In this case, the ACC is automatically
switched off.  ACC: Take action!
The message for the driver is displayed if,
when the vehicle starts up on a hill with a
mild slope, the vehicle rolls back even al-
though the ACC is activated. Apply the brake
to stop the vehicle from moving/colliding
with another vehicle.  ACC: speed limit
The message for the driver is displayed if, in
vehicles with manual gearbox, the current
speed is too low for the ACC mode.
The speed to be stored must be at least
30 km/h (18 mph). The speed limiter
switches off if the speed falls below 20 km/h
(12 mph).  ACC: available as of the 2nd
gear The ACC is operational as of the 2nd gear
(manual g
earbox).
 ACC: engine speed
The message for the driver is displayed if,
when the ACC accelerates or brakes, the driv-
er does not shift up or down a gear in time,
which means exceeding or not reaching the
permissible engine speed. The ACC switches
itself off. A buzzer warning is heard.  ACC: clutch pressed
Vehicles with a manual gearbox: pressing the
clutch pedal for longer abandons control
mode. Door open
Vehicles with automatic gearbox: the ACC
cannot be activated with the vehicle station-
ary and the door open. WARNING
There is a danger of rear collision when the
minimum dis t

ance to the vehicle in front is
exceeded and the speed difference between
both vehicles is so great that a speed reduc-
tion by the ACC will not suffice. In this case
the brake pedal should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions pr
operly.
● “Stepping” on the accelerator may cause
the ACC
not to intervene in braking. Driver braking will have priority over intervention by
the speed c
ontr

ol or adaptive cruise control.
● Always be ready to use the brakes!
● Observe country-specific provisions gov-
erning ob
ligatory minimum distances be-
tween vehicles. Note
● The pr ogrammed s

peed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivat
ed during acceleration or else the
ESC is activated in Sport* Mode
( ››› page 120), the ACC switches off automati-
cally.
● In vehicles with the Start-Stop system, the
engine swit
ches off automatically during the
ACC stopping phase and restarts automatical-
ly to begin driving. 220

Operation
SEAT Drive Profile* Intr oduction SEAT Drive Profile enables the driver to
choo
se betw
een four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
In the FR and X-PERIENCE models equipped
with dynamic chassis control, the Comfort
profile is also available.
In the Leon Cupra model the four profiles are Comfort , Sport, Cupra and Individual .
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hic
l
e,

SEAT Drive Profile can operate on the
following functions: Engine
Depending on the pr

ofile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when Eco mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco 1)
mode activates the In-
ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles, Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)
DCC continuously adapts the shock absorb-
ers to the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting .Address
Pow
er steering becomes more robust in
Sport mode to enable a sportier driving
style. In the Leon Cupra the power steering
becomes more robust in Cupra mode.

Towing bracket device
Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 254.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 289, Technical
specifications.
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
The maximum permissible tyre pressure val-
ues are shown on the sticker on the back of
the left front door frame. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 252.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 252. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 251

The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Trailer maximum electricity consumption

Note
● If the r e

ar lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
● If the trailer absorbs excessive electric cur-
rent, the v
ehicle electronics may be dam-
aged.
● Never connect the trailer's electric system
directly t
o the electrical connections of the

Operation
Anti-theft alarm When the vehicle is locked, the alarm is trig-
ger
ed when the el
ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 133.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 119. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

then the tank must be refilled. This is neces-
sary to ensure that the system works proper-
ly, as well as the fuel quality required for driv-
ing with petrol.
