2014 Seat Leon 5D park assist

Operation
When accelerating, the gearbox automatical-
ly shifts up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
overrevving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.
Driving tips The gearbox changes gear ratios automatical-
ly as the vehicle moves.
The engine can only start with the selector
lever in the position P or N. At low tempera-
tures, below -10°C (50°F), the engine can on-
ly start with the selector lever in the position
P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the
button on the selector lever handle), move
the selector lever to the desired position,
for instance D
› ››
page 133, and release the
interlock button.
– Wait for the gearbox to engage the gear (a
slight movement can be felt). –
Release the brake and press the accelerator
››› .
Stopping briefly – Apply the foot brake to hold the vehicle
briefly when stationary (for instance at traf-
fic lights). Do not press the accelerator.
Stopping/Parking
If the driver door is opened and the selector
lever is not in position P, the vehicle could
move. The driver message will be:  Gear
change: selector lever in the drive position!. Additionally, a buzzer will sound.
– Press and hold the brake pedal ››› .
– Apply the handbrake.
– Move the selector lever to position P.
Holding the car on a hill – Always apply the brake pedal firmly to pre-
v ent

the vehicle from “moving backwards;
if necessary, apply the handbrake” ››› .
Do not
try to stop the vehicle “rolling back”
b

y increasing the engine speed when a
gear is engaged (pressing the accelerator)
››› .
Moving off uphill in vehicles without Hill
start assistant* – Apply the handbrake. –
Once you have engaged a gear press the
accelerator carefully and disengage the
handbrake.
Moving off uphill in vehicles with Hill start
assistant* – Once you have engaged a gear, release the
footbrake and press the accelerator
››› page 147, Hill driving assistant*.
Driving down hills: in some situations (on
mountain roads or when towing a trailer or
caravan) it can be advantageous to switch
temporarily to the manual gearbox pro-
gramme so that the gear ratios can be selec-
ted manually to suit the driving conditions
››› .
On level ground it is sufficient to move the
selector lever to position P. On slopes, first
engage the parking brake and then put the
selection lever into the P position. This
avoids overloading the locking mechanism
and it will be easier to move the selector lev-
er from position P. WARNING
Observe the safety warnings ››› in Selector
lever positions on page 133.
● Never allow the brake to rub and do not use
the brake pedal too often or for long periods.
Constant braking causes overheating in the 136

Driver assistance systems
Note
● You can control whether the engine should
switch off or not by reducing or increasing the
brake force applied. While the vehicle re-
mains stopped, the engine will not stop if the
brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for exam-
ple. As soon as strong pressure is applied to
the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stopping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual gearbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes
The system can interrupt the Start-Stop mode
frequently for different reasons.
The engine does not switch off
Before the stopping phase, the system veri-
fies whether certain conditions are met. The
engine
does not
sw
it ch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required temperature for the Start-Stop
mode. ●
The interior temperature selected for the air
conditioner has not yet been reached.
● The interior temperature is very high/low.
● Defrost function button activated
›››  page 26.
● The park

ing aid* is switched on.
● The battery is very low.
● The steering wheel is overly turned or is be-
ing turned.
● If there is a danger of misting.
● After engaging reverse gear.
● In case of a very steep gradient.
The indication  is shown on the instrument
panel display, and in addition, the driver in-
formation system* shows, .
The engine starts by itself
During a stopping phase the normal Start-
Stop mode can be interrupted in the follow-
ing situations: The engine restarts by itself
without involvement from the driver.
● The interior temperature differs from the
value selected on the air conditioner.
● Defrost function button activated
›››  page 26.
● The brak

e has been pressed several times
consecutively.
● The battery is too low.
● High power consumption. Note
In vehicles with an automatic gearbox, if the
selector lever is placed in position D, N or S
after engaging reverse gear, the vehicle must
be driven at a speed faster than 10 km/h (5
mph) for the system to return to conditions in
which the engine can be stopped. Manually switching on/off the Start-
Stop system

ary and the door open.
Deactivating the Adaptive Cruise
Control ACC temporarily in certain
situations In the following situations the Adaptive
Cruise Control (ACC) should be deactivated
due to the system's limitations
››› :
● When changing lanes, on tight bends and
roundabouts, in acceleration and decelera-
tion lanes on motorways or in sections with
road works to prevent involuntary accelera-
tion to reach the programmed speed.
● When going through a tunnel, as operation
could be affected.
● On roads with several lanes, when other ve-
hicles are driving more slowly in the overtak-
ing lane. In this case, slower vehicles will be
overtaken on the right.

Driver assistance systems
Factors that may affect how the radar sensor
operates
If laser sensor operation is impaired, due to
heavy rain, spray, snow or mud, the ACC is
deactivated temporarily. The relevant text
message will appear in the dash panel dis-
play. If necessary, clean the radar sensor.
When the radar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again.
ACC operation may be affected by a strong ra-
dar reverse reflection, for example in a closed
car park.
Trailer towing
When driving with trailer the ACC controls
less dynamically.
Overheated brakes
If the brakes overheat, for example after
abrupt braking or in long and steep slopes,
the ACC may be deactivated temporarily. The
relevant text message will appear in the dash
panel display. In this case, adaptive cruise
control cannot be activated.
Adaptive cruise control can be reactivated
once brake temperature has cooled suffi-
ciently. The message will disappear from the
instrument panel display. If the message ACC
not available remains on for quite a long time it means that there is a fault. Contact a speci-
alised workshop. SEAT recommends visiting
a SEAT dealership.
WARNING
If the message ACC ready to start appears on
the instrument panel display and the vehicle
in front starts up, the vehicle will start up au-
tomatically. In this case the radar sensor may
not detect obstacles on the road. This could
cause an accident and serious injuries.
● Before driving off, check that the road is
clear. If necessary, apply the brake. Monitoring system Front
Assist*
Introduction The Front Assist Monitoring system helps to
prevent rear collisions.
The Front Assist can warn the driver of colli-
sion hazards, prepare the vehicle for emer-
gency braking in case of danger, assist the
driver on braking and cause automatic brak-
ing.
The Front Assist is not a replacement for
driver awareness.Distance warning
If the system detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 210 km/h (130 mph)
››› Fig. 158 .
The w arnin
g moment varies depending on
the traffic situation and driver behaviour.
Pre-warning
If the system detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 210 km/h (130 mph)
››› Fig. 158.
The warnin
g moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› .
Critical warning
If the driver fails to react to the pre-warning,
the system may actively intervene in the
brakes when driving at a speed of between
approximately 30 km/h (18 mph) and
210 km/h (130 mph), generating a brief jolt
to warn of the imminent collision. »

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

● At speeds above 200 km/h (125 mph)
● When cornering
● On roads in poor condition
● In unfavourable weather conditions
● When a sporty driving style is employed
● In the event of a serious distraction to the

Tiredness detection will be restored when the
vehicle is stopped for more than 15 minutes,
when the ignition is switched off or when the
driver has unbuckled their seat belt and
opened the door.
In the event of slow driving during a long pe-
riod of time (below 65 km/h (40 mph) the
system automatically re-establishes the tired-
ness calculation. When driving at a faster
speed the driving behaviour will be recalcula-

Parking aid
General information Various systems are available to help you
when parking or manoeuvring in tight spaces, depending on the equipment fitted
on your vehicle.
The
rear parking aid
is an audible assistant
th
at warns about obstacles located behind
the vehicle ››› page 174.
Durin

g parking, the
parking system plus as-
sists you visually and audibly about obsta-
cles detected in front and behind
the vehicle
››› page 174. WARNING
● Always pay attention, also when looking
straight ahead, to traffic and the vehicle sur-
roundings. The assistance systems are not a
replacement for driver awareness. When in-
serting or removing the vehicle from a park-
ing space, or when performing similar ma-
noeuvres the driver always assumes the re-
sponsibility.
● Take into account that the system is not al-
ways in conditions to recognise or represent
certain surfaces, such as dress fabric: Risk of
causing an accident!
● The sensors and cameras have blind spots,
making the detection of people and objects
impossible. Pay special attention to children
and animals: Risk of causing an accident!
● Always keep visual control of the vehicle
surroundings: use the rear vision mirrors for
additional help. CAUTION
● Under certain circumstances, the system
does not detect or display certain objects:
– Objects such as snow chains, trailer draw
bars, bars or fences.
– Objects that are located above the sen-
sors, such as protrusions in a wall.
– Objects with certain surfaces or struc-
tures, such as wire mesh fences or pow-
der snow.
● Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. In
certain circumstances, objects such as high kerbs that could damage the bottom of the
vehicle are not detected either.
● If the first warning from the Park Pilot is ig-
nored, the vehicle could suffer considerable
damage.
● The knocks or damage on the radiator
grille, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In certain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g: » 173

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)

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. »
