2015 Seat Leon Sportstourer lane assist

Operation
●
In comp l
ex driving situations, the Front As-
sist may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, f
or example, by dirt or because the ra-
dar sensor has lost its settings, the system
may issue unnecessary warnings and inter-
vene inopportunely in the braking.
● During driving, the Front Assist does not re-
act to peop
le or animals or vehicles crossing
your path or which approach you head-on in
the same lane.
● The driver must always be ready to take
over the c
ontrol of the vehicle. Note
● When the Front As

sist causes a braking,
the brake pedal is “harder”.
● Automatic interventions by the Front Assist
on the brake
s may be interrupted by pressing
the clutch, accelerator or moving the wheel.
● If the Front Assist does not work as descri-
bed in this c
hapter (e.g. in intervenes several
times unnecessarily), switch it off. Have the
system checked by a specialised workshop.

120 m.
The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: Front Assist: No sensor vision! If necessary clean the ra-
dar sensor ››› .
When the r a

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)

Introduction 

›› ›

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
contact a specialised workshop.
● If there is a fault in the system, have it
check
ed by a specialised workshop. Indications on the display and lamps

Operation Fig. 208
In the windscreen: field of vision of
the Lane As s
i

st system camera. Using the camera located in the windscreen,
the Lane As
s
i

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.
Steering wheel vibration
The following situations can cause vibration
in the steering wheel and require the driver
to take active control of driving:

Operatin

g and safety warnings WARNING
● The Re ar As

sist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of
vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect.
● Some objects may, due to the resolution of
the disp
lay screen - not be displayed in a sat-
isfactory manner or may not be displayed at
all. Take special care with thin posts, fences,
railings or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not pos
sible to represent people or objects
(small children, animals and certain objects cannot be detected in its field of vision). Mon-
itor the
v

ehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow
, and do not cover it.
● The system is not a replacement for driver
awar
eness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style
at all times to suit visibility, weather, road
and traffic conditions.
● Do not be distracted from the traffic by
looking at
the screen.
● The images on the rear assist screen are
only tw
o-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines
displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load.
● In the following situations, the objects or
other vehic
les shown in the navigation sys-
tem display appear to be further away or
closer than they really are: Pay special atten-
tion:
– On moving from a horizontal plane to a
slope.
– On moving from a slope to a horizontal
plane. –
If the v

ehicle is heavily loaded at the
rear.
– When the vehicle approaches objects
that are not on the ground surface or are
jutting out from it. These objects may al-
so be outside the camera's angle of vi-
sion when reversing. Note
● It is

important to take great care and pay
special attention if you are not yet familiar
with the system.
● Rear assist will not be available if the vehi-
cle's
rear lid is open. Instructions for use

Care and maintenance
Camera sensors and lenses ●
Use a small brush to remove snow and a
de-icer s pr
ay to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dr
y cloth.
● Moisten the camera lens using a standard
alcohol-b
ased glass cleaning agent and
clean the lens with a dry cloth. In the active
lane assist*, the area in front of the lens is
normally cleaned with the windscreen wash-
er. CAUTION
● When y ou c

lean the vehicle with a pressure
washer:
–Stay a suitable distance from the sensors
on the front and rear bumpers.
– Do not clean the camera lenses or sur-
rounding area with the pressure washer.
● Never use warm or hot water to remove
snow and ic
e from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Waxing and polishing
Care
W
ax
in

g protects the paintwork. It is time to
apply a coat of good wax when water no lon- ger forms droplets
and ro
lls off the clean
paintwork.
Even if a wax solution is used regularly in the
vehicle washing tunnel, it is advisable to pro-
tect the paint with a hard wax coating at least
twice a year.
In the summer, you will find it is much easier
to remove dead insects (which accumulate
on the bumper and the front of the bonnet) if
the car has been treated with care products
recently.
Polishing
Polishing is only necessary if the paint has
lost its shine, and the gloss cannot be
brought back by putting on wax.
If the polish does not contain wax, a wax
product should be applied after polishing. CAUTION
● Do not u se po

lishes and hard wax on pain-
ted parts with a matt finish or on plastic
parts.
● Do not apply paint polishes to the side trim
that ru
ns around the panoramic roof and ends
on the windscreen. However, it can be treated
with hard wax. Trims
In respect for the environment, the silver-
pl
at

ed trims on the body are made of pure
aluminium (they do not contain chrome).
Dirt or marks on the trim mouldings should
be removed with a cleaning product with a
neutral PH (do not use a chrome cleaner).
Body polish is also unsuitable for use on trim
mouldings. The intensive cleaning fluids of-
ten used before the car goes into a car wash
may contain alkaline substances, which can
cause dull or milky patches when they dry
out.
SEAT Official Services carry stocks of cleaning
products which have been tested for use on
your vehicle and are not harmful to the envi-
ronment.
Plastic parts Plastic parts are cleaned with a power wash-
er
. If
thi

s is not sufficient, plastic parts
should only be treated with a special solvent-
free plastic cleaning agent . Do not use paint-
work cleaners, polishes or wax on plastic
parts.
