2015 Seat Leon SC Owner's manual

Driver assistance systems
Front Assist operation may be affected by a
s tr
on
g radar reverse reflection. This may oc-
cur, for example, in a closed car park or due
to the presence of metallic objects (e.g. rails
on the road or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect Front Assist operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, Front As-
sist operation may be affected. So structural
modifications should only be made by speci-
alised workshops. SEAT recommends visiting
a SEAT dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and Front Assist opera-
tion may be affected. So repair work should
only be made by specialised workshops.
SEAT recommends visiting a SEAT dealership
for this purpose. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged or has lost its settings, dis-
connect the Front Assist. This will avoid pos-
sible damage. If this occurs have it adjusted.
● The sensor may become damaged or lose
its settin
gs when knocked, for example, dur- ing a parking manoeuvre. This may compro-
mise the sy
s

tem's efficacy or disconnect it.
● Repairs to the radar sensor require special-
ist
knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose.
● Clean away the snow with a brush and the
ice pref
erably with a solvent-free de-icer
spray. Operating the Front Assist monitoring

● If the vehicle is on a test bed.
● When the radar sensor is damaged.
● If the radar sensor takes a heavy knock, for
e x
amp

le in a rear collision.
● If it intervenes several times unnecessarily. ●
If the ra
dar sensor is covered temporarily
with some kind of accessory, such as an ad-
ditional headlight or the like.
● When the vehicle is to be loaded on a lorry,
ferry
or train. WARNING
If the Front Assist is not switched off in the
sit uation

s described, serious accidents and
injuries may occur.
● Switch off the Front Assist in critical situa-
tions. System limitations
The Front Assist Monitoring System has cer-
t
ain ph
y

sical limitations inherent in the sys-
tem. Thus, in certain circumstances some of
the system's reactions may be inopportune
or be delayed from the driver's standpoint.
So pay attention in order to intervene if nec-
essary.
The following conditions may cause the Front
Assist Monitoring System not to react or do
so too late:
● On taking tight bends.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged. ●
If the ASR ha
s been manually disconnec-
ted.
● If the ESC is controlling.
● If several brake lights of the vehicle or elec-
trically
connected trailer are damaged.
● If the radar sensor is dirty or covered.
● If there are metal objects, e.g. rails on the
roa
d or sheets used in road works.
● If the vehicle is reversing.
● If the vehicle over-accelerates.
● In case of snow or heavy rain.
● In case of narrow vehicles, such as motor-
bike
s.
● Misaligned vehicles.
● Vehicles crossing the other's path.
● Vehicles approaching in the opposite direc-
tion.
● Special loads and accessories of other ve-
hicle
s that jut out over the sides, backwards
or over the top.

City Emergency braking function Fig. 205
On the instrument panel display:
pr e-w
arnin
g message The City Emergency braking function is part
of
the Fr
ont

Assist monitoring and is active
whenever the system is switched on.
Depending on the equipment, the pre-warn-
ing function can be switched on or off in the
Easy Connect system with the button  and
the f u
nction b

uttons  and
Driv
er As
s ist›››
 pag
e 28.
The C ity Emergency braking function picks
up, at speeds between 5 km/h (3 mph) and
30 km/h (19 mph) approximately, the traffic
situation in front of the vehicle up to a dis-
tance of about 10 m. If the system detects a possible collision with
a v
ehic

le in front of it, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er f

ails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.
Status display
Automatic deceleration by means of the City
Emergency braking function is displayed on
the instrument panel by means of the pre-
warning ››› Fig. 205 1)
. WARNING
The smart technology included in the City
Emerg ency

braking function cannot defy the
laws of physics. The driver is always respon-
sible for braking in time.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The City Emergency braking function alone
cannot pr
event accidents or serious injury.
● In complex driving situations, the City
Emergency
braking function may issue unnec-
essary warnings and intervene inopportunely in braking, such as in work areas or if there
are met
a

l rails.
● If the operation of the City Emergency brak-
ing fu
nction is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● During driving, the City Emergency braking
function doe
s not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane. Note
● When the City Emer

gency braking function
causes a braking, the brake pedal is “hard-
er”.
● Automatic interventions on the brakes by
the City Emer
gency braking function may be
interrupted by pressing the clutch, accelera-
tor or moving the wheel.
● The City Emergency braking function can
brake the
vehicle until it stops completely.
However, the brake system does not halt the
vehicle permanently. Use the foot brake!
● If several inopportune intervenes occur,
switc
h off the Front Assist and with it the City
Emergency braking function. Take it to a spe-
cialised workshop, SEAT recommends visiting
a SEAT dealership. »1)

table on page 2 WARNING
The intelligent technology in the Lane Assist
sys t

em cannot change the limits imposed by
the laws of physics and by the very nature of
the system. Careless or uncontrolled use of
the Lane Assist system may cause accidents
and injury. The system is not a replacement
for driver awareness.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● Always keep your hands on the steering
wheel so it c
an be turned at any time.
● The Lane Assist system does not detect all
roa
d markings. The road surfaces, road struc-
tures or objects in poor condition can be in-
correctly detected as road markings under
certain circumstances by the Lane Assist sys-
tem. In such situations, switch the Lane As-
sist system off immediately. ●
Ple a

se observe the indications on the in-
strument panel and act as is necessary.
● Always pay attention to the vehicle's sur-
roundin
gs.
● When the area of vision of the camera be-
comes
dirty, covered or is damaged, the Lane
Assist system function can be affected. CAUTION
In order to avoid influencing the operation of
the sy st

em, the following points must be tak-
en into account:
● Regularly clean the area of vision of the
camera and k
eep it in a clean state, without
snow or ice.
● Do not cover the area of vision of the cam-
era.
● Check

that the area of vision of the wind-
scr
een camera is not damaged. Note
● The Lane Ass i

st system has been exclusive-
ly developed for driving on paved roads only.
● If the Lane Assist system does not work as
desc
ribed in this chapter, do not use it and

st system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a corrective steering movement . This move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.

Intr oduction 

›› ›

table on page 2
SEAT Drive Profile enables the driver to
choose between four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
204

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
