ESP Seat Leon SC 2015 Repair Manual

Driver assistance systems
In the FR and X-PERIENCE models equipped
w ith dy
n
amic chassis control and Navi Sys-
tem Plus, 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 profile 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 r

educed.
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)

››› table on page 2
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
Power 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.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption. Ambient lighting
The ambient lightin
g guides located in the in-
terior front door panels of the Leon FR and
the Leon Cupra change colour from white to
red depending on the driving mode selected.
Adaptive Cruise Control (ACC) 2)
According to the active driving profile, the ac-
celeration gradient of the adaptive cruise
control varies.
Electronic self-locking differential 2)
The self-locking differential adapts its behav-
iour depending on the driving profile chosen.
Normal mode or Cupra mode can be selected
to prioritise improved traction in sport driv-
ing. 1)
In the Leon Cupra model, Ec o
mode is selected
through the Individual profile.
2) Applies to the Leon Cupra model.

Never driv e if

you are tired.
● The system does not detect the tiredness of
the driver in al

● If necessary, switch on the Easy Connect
syst
em.
● Engage reverse gear or turn the selector
lever t

ing cases: ●
If the imag

● If the area behind the vehicle is not dis-
pla
yed very clearly or is incomplete.
● If the vehicle is heavily loaded at the rear.
● If the position and installation angle of the
camera h
ave been changed, e.g. after a rear-
end collision. Have the system checked by a
specialised workshop.
Familiarising yourself with the system
To familiarise yourself with the system, the
orientation lines and their function, SEAT rec-
ommends practising parking and manoeu-
vring with the rear assist in a place without
too much traffic or in a car park when there
are good weather and visibility conditions.
Cleaning the camera lens
Keep the camera lens clean and clear of snow
and ice:
● Moisten the lens using a normal alcohol-
based gl
ass cleaning product and clean the
lens with a dry cloth.
● Remove snow using a small brush.
● Use de-icing spray to remove any ice. CAUTION
● Never u se abr

asive cleaning products to
clean the camera lens.
● Do not use hot or warm water to remove ice
or snow fr
om the camera lens. Doing so could
damage the camera. Parking and manoeuvring with the

Towing bracket device
T o
w
ing bracket device*
Introduction The towing bracket device fitted to your vehi-
cl
e, be it

factory-fitted or a genuine SEAT ac-
cessory, meets all the national technical and
legal requirements for towing.
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle. If the trailer is equip-
ped with a 7-pin connector you can use the
corresponding available adaptor that is a
genuine SEAT accessory.
The maximum authorised towing load is
80 kg. WARNING
● Bef or

e each journey, make sure that the de-
tachable ball joint is properly fitted and se-
cured in its housing.
● If the detachable ball joint is not properly
fitted and secur
ed, do not use it.
● Do not use the towing bracket device for
tow
ing if it is damaged or has missing parts.
● Do not modify or adapt the towing device
connection.
● Never u

nhook the detachable ball joint
when the trail
er is hitched. CAUTION
Handle the detachable ball joint with care in
order t o av

oid damaging the bumper paint-
work. Note

The ball joint is fitted and removed by hand.
The towing device bracket is supplied with a

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 228.
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 figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
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
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. 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 226.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 226. 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. 225

The v

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

● If the trailer absorbs excessive electric cur-
rent, the v
