2014 Seat Leon 5D ignition

Operation
●
While you are selecting a gear and the vehi-
cle is stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if the engine is running and a gear is en-
gaged. If you have to leave your vehicle while
the engine is running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the selector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 198, Work in the engine compart-
ment. Note
● If the selector lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ››› page 229. Selector lever lock
Fig. 143
Selector lever lock. The selector lever lock prevents gears from
being engaged inadvertently, so that the ve-
hicle is not set in motion unintentionally.
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time
pr e
ss in the interlock button.
Automatic selector lever lock
With the ignition switched on, the selector
lever is locked in the positions P and N. The
brake pedal must be pressed to release the
lever while pressing the release button if the
selector lever is in the position P. As a re-
minder for the driver, with the lever in posi-
tions P or N the following message will be
shown on the display: When stationary, apply footbrake while se-
lecting a gear.
The selector lever lock only works if the vehi-
cle is stationary or driving at speeds up to 5
km/h. At higher speeds the selector lever
lock in the N position is disengaged automat-
ically.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 143.
Safety

interlock for ignition key
Once the ignition has been turned off, the
key may be removed only if the gear selector
is in position P. While the key is not in the ig-
nition, the selector lever is locked in position
P.

Operation
Note
The Official Service or a specialist workshop
can tell you if your vehicle is equipped with
this system. Start-Stop system*
Description and operation The Start-Stop system helps save fuel and re-
duce CO
2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode ● The driver door must be closed.
● The driver must have their seat belt fas-
tened.
● The bonnet must be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) since the last stop.
● The vehicle cannot be towing a trailer. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop system is switched off when working in
the engine compartment ››› page 149. CAUTION
The Start-Stop system must always be
switched off when driving through flooded
areas ››› page 149. Stop/Start the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and release the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play. –
When the clutch pedal is pressed the en-
gine will start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and keep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
di s
play.
– When you take your foot off the brake pedal
the engine will start up again. The warning
lamp will switch off.
Additional information related to the
automatic gearbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.

Operation
Note
The system is automatically switched on each
time the engine is deliberately stopped dur-
ing a stopping phase. The engine will start
automatically. Driver messages on the instrument
panel display
Start-Stop system deactivated. Start the
engine manually
This driver message is displayed when cer-
tain conditions are not met during the stop-
ping phase and the Start-Stop system cannot
restart the engine. The engine must be star-
ted manually.
Start-Stop system: Fault! Function not available
There is a fault in the Start-Stop system. Take
the vehicle to a workshop to have the fault
repaired.
Cruise control system (CCS)* How it works The cruise control system (CCS) is able to
maintain the set speed from 20 km/h (15
mph). The CSS only reduces vehicle speed by ceas-
ing to accelerate, not by actively braking the
vehicle
››› .
WARNING
Use of the cruise control could cause acci-
dents and severe injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the distance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpaved roads.
● Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
control system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a constant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Warning and control lamp

Safety
The essentials

Operation
The following conditions may lead the ACC
not to react:
● If the accelerator is pressed.
● If there is no gear engaged.
● If the ESC is controlling.
● If the driver is not wearing his/her seat
belt.
● If several brake lights of the vehicle or elec-
trically connected trailer are damaged.
● If the vehicle is reversing.
● Driving faster than 160 km/h (100 mph). WARNING
There is a danger of rear collision when the
minimum distance to the vehicle in front is
exceeded and the speed difference between
both vehicles is so great that a speed reduc-
tion by the ACC will not suffice. In this case
the brake pedal should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions properly.
● “Stepping” on the accelerator may cause
the ACC not to intervene in braking. Driver
braking will have priority over intervention by
the speed control or adaptive cruise control.
● Always be ready to use the brakes!
● Observe country-specific provisions gov-
erning obligatory minimum distances be-
tween vehicles. Note
● The programmed speed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivated during acceleration or else the
ESC is activated in Sport* Mode ( ››› page 81),
the ACC switches off automatically.
● In vehicles with the Start-Stop system, the
engine switches off automatically during the
ACC stopping phase and restarts automatical-
ly to begin driving. Vehicles with an automatic gearbox
If the vehicle is equipped with automatic
gearbox, the ACC can brake the vehicle until
it stops completely if a vehicle in front of it
stops.
The ACC will still be available for a few sec-
onds. The vehicle will restart by itself if the
vehicle in front moves (traffic jam assistant).
Disconnection criteria
The ACC will switch off if the driver applies
the brake pedal or the driver's door is
opened.
If the vehicle in front remains stationary for
more than 3 seconds, the ACC will also
switch off for safety reasons.
In this case the
driver should take control and apply the
brake. In the latter case, when the ACC is switched
off with the vehicle stationary, the vehicle
has to be braked by the pedal, since al-
though the car is idling it can move, as there
is a gear engaged.
Restarting the vehicle with the ACC manually
The ACC can be activated again by moving
the lever to position
2
››› Fig. 154 . WARNING
Your vehicle can start up even if there is an
obstacle between your vehicle and the vehi-
cle detected in front. Risk of accident! CAUTION
● If your vehicle with ACC does not start up
as expected, you can drive off by briefly step-
ping on the accelerator.
● The Start-Stop system usually acts if you
are driving with ACC. 156

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

If the Front Assist is not switched off in the
situations 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-
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.
