2014 Seat Leon 5D light

Operation
Deceleration until the vehicle has stopped
(only vehicles with automatic gearbox)
If the vehicle in front slows down and stops,
the ACC will also slow down and halt the ve-
hicle. After approximately 3 seconds the sys-
tem will inform the driver that he or she
should take control of the vehicle by means
of an audible and visual warning on the in-
strument panel.
Starting driving after a stopping phase (only
vehicles with automatic gearbox)
After a stopping phase the ACC may begin
driving automatically when the vehicle in
front drives off.
Overtaking
When the turn signal lights up before the ve-
hicle begins an overtaking manoeuvre, the
ACC accelerates the vehicle automatically
and thus reduces the distance from the vehi-
cle in front.
When the vehicle enters the overtaking lane,
if the ACC does not detect another vehicle in
front, it accelerates until it reaches the pro-
grammed speed and maintains it.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever backwards ›››
page 154. Driving through a bend
On entering or exiting bends, the radar sen-
sor may no longer determine the vehicle in
front or react to a vehicle in the adjacent lane
››› Fig. 156
A. In these situations the vehicle
may brake unnecessarily or fail to react to re-
act to the vehicle in front. In this case, the
driver has to intervene by accelerating or in-
terrupting the braking process by applying
the brake or pushing the third lever back-
wards ››› page 154.
Drivin

g in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 156
B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary. Other vehicles changing lanes
Vehicles changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act
››› Fig. 157 C
. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it
››› Fig. 157 D
. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly.

Driver assistance systems
Radar sensor Fig. 159
On the front bumper: radar sensor. A radar sensor is installed on the front bump-
er to determine the traffic situation
››› Fig. 159 1 . This sensor can detect vehi-
cles in front up to a distance of approximately
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 vi- sion! If necessary clean the radar sensor ››› .
When the radar sensor begins to operate
properly again, the Front Assist will automati-
cally be available again. The message will
disappear from the instrument panel display.
Front Assist operation may be affected by a
strong 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 damaged 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 settings when knocked, for example, dur-
ing a parking manoeuvre. This may compro-
mise the system'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 preferably with a solvent-free de-icer
spray. Operating the Front Assist monitoring

tain physical 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 has 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.

cleaning vehicles,
– In downpours, intense snow or dense ex-
haust gases
● In order to familiarise yourself with the sys-
tem, 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 condi-
tions.
● The volume and tone of the warnings can
be modified, in addition to the indications
››› page 176.
● In v
ehicles without a driver information
sys

tem, these parameters can be modified in
a SEAT Official Service or in a specialised

● Please observe information on towing a
trailer ››› page 177.
● The dis

play on the Easy Connect screen
shows a slight time delay.
● To ensure that the parking aid works prop-
erly, 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 obsta-
cle, 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 185.
The approximate measurement range of the
sensors is:
rearside0.90 m
centre1.60 m As you approach the obstacle, the time inter-
val between the audible warnings will be re-
duced. 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 173 , ›

tivation Switching on
– Engage reverse gear or
– Press the switch  in the centre console
››› Fig. 169 . A short confirmation signal will
be he ar
d and the button symbol will light
up yellow.
With certain equipment (Adaptive Cruise Con-
trol - ACC), the system will be activated auto-
matically when the vehicle reverses for a cer-
tain distance (about 10 cm if an obstacle is
detected in the rear area and about 20 cm if
no obstacle is detected in the rear area).
Switching off
– Drive forwards at more than 10 km/h (6
mph), or
– Press the  button, or
– switch the ignition off. Segments of the visual indication
The distance of separation from the obstacle
can be estimated using the segments around
the vehicle.
The graphic display of the segments varies
according to the vehicle's equipment:
The yellow trail indi-
cates the vehicle's expected journey
based on the steering wheel angle. A
white
segment is displayed when the
obstacle is not within the vehicle's tra-
jectory or the direction of travel would
avoid it entering the vehicle's trajectory.
If the obstacle is within the vehicle’s tra-
jectory, a yellow segment is displayed
(at

a distance of more than 30 cm) or a
red
segment (at a distance of less than
30 cm) at the same time as the corre-
sponding audible warning sounds.
The
yellow trail indicates the vehicle's ex-
pected journey based on the steering
wheel angle. A white segment is dis-
pl

ayed when the obstacle is not within
the vehicle's trajectory or the direction
of travel would avoid it entering the ve-
hicle's trajectory. If the obstacle is with-
in the vehicle’s trajectory, a red
segment
is displayed at the same time as the cor-
responding audible warning sounds. »
