2014 Seat Leon 5D gearbox

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.

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

Adaptive Cruise Control ACC* Introduction Fig. 149
Detection area. The adaptive cruise control (ACC)
is an exten-
sion of the normal cruise control system
(CCS)
›
›› .
The ACC function allows the driver to estab-
lish a cruise speed of between 30 and 160
km/h (18 and 100 mph), as well as the tem-
porary distance required with regard to the
vehicle in front. The ACC function will adapt
the vehicle's cruise speed at all times, main-
taining a safe distance with the vehicle in
front.
The ACC function is based on a radar sensor
that can measure the distance to the vehicles
in front.
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.
Driver intervention prompt
During driving, the ACC is subject to certain
limitations inherent in the system. In other
words, in certain circumstances the driver will
have to adjust speed him or herself, as well
as the distance from other vehicles.
In this case, the instrument panel screen will
warn you to intervene by applying the brake
and a warning tone will be heard

The essentials

Operation
ACC operation may be affected by a strong ra-
dar reverse reflection. This may occur, for ex-
ample, 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 ACC operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, ACC op-
eration may be affected. So structural modifi-
cations should only be made by specialised
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 ACC operation may
be affected. So repair work should only be
made by specialised workshops. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. CAUTION
If you have the sensation that the radar sen-
sor is damaged or has lost its settings, dis-
connect the ACC. This will avoid possible
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 Adaptive Cruise Control

C ondition
s for the adaptive cruise control to
be activated
● The selector lever must be at the D or S po-
sition or in the tiptronic selection track. In
manual gearbox any forward gear must be
engaged, except the 1st gear.
● In vehicles with manual gearbox, if there is
no programmed speed, drive at least at
30 km/h (18 mph).
Speed control
When the ACC is connected, speed can be
programmed and adjusted. The programmed
154

speed must be different from the speed at
which the vehicle travels if the distance is be-
ing adjusted at the time.
What functions can be operated?
If you activate the ACC the current speed can
be programmed as the “control speed”.
During driving, control can be operated at
any time and the speed also modified.
The following settings can also be adjusted:
● Distance.
● Driving Programme.
● Driving style.

In wet

road conditions, you should always set
a larger distance with regard to the vehicle in
front than when driving in dry conditions.
The following distances can be preselected:
● Very short
● Short
● Media ●
Long
● Very long

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

››› 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

● To inc

rease/reduce the distance one level,
press the rocking button again towards the
left/right. The instrument panel display
modifies the distance between both vehicles. If the vehicle approaches another vehicle de-
tected in front of it, the ACC reduces the
speed accordingly and then controls the ad-
justed distance. If the vehicle detected in
front accelerates, the adaptive cruise control
will also accelerate up to the target speed
programmed at most.
The greater the speed, the greater the dis-
tance in metres should be

With regard to distance setting, the driver is
responsible for observing country-specific
legislation. Message texts
