Seat Leon Sportstourer 2014 Owner's manual

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

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

Changing gear in CCS mode
The CCS decelerates as soon as the clutch
pedal is pressed, intervening again automati-
cally after a gear is engaged.
Travelling down hills with the CCS
When travelling down hills the CCS cannot
maintain a constant speed. Slow the vehicle
down using the brake pedal and reduce
gears if required. B C
D Automatic off
The cruise control system (CCS) is switched
off automatically or temporarily:
●
If the system detects a fault that could af-
fect the working order of the CCS.
● If you press and maintain the accelerator
pedal for a certain time, driving faster than
the stored speed.
● If the dynamic driving control systems in-
tervene (e.g. ASR or ESC).
● If the airbag is triggered.
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

Operation
WARNING
The intelligent technology in the ACC cannot
overcome the system's inherent limitations
or change the laws of physics. If used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a re-
placement for driver awareness.
● Adapt your speed and safe distance to the
vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Do not use the ACC when visibility is bad,
on steep roads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
● Never use the ACC when driving off-road or
on unpaved roads. The ACC has been de-
signed for use on paved roads only.
● The ACC does not react on approaching a
fixed obstacle, such as the tail of a traffic
jam, a damaged vehicle or a vehicle stopped
at the traffic lights.
● The ACC does not react to people or animal
or vehicles crossing your path or which ap-
proach you head-on in the same lane.
● If the ACC does not reduce speed sufficient-
ly, brake the vehicle immediately by applying
the pedal.
● If you are driving using the spare wheel,
the ACC system could automatically switch
off during the journey. Switch off the system
when starting off. ●
If the vehicle continues to move involuntar-
ily after a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driver interven-
tion prompt, adjust the distance yourself.
● The driv er shou
ld be ready to accelerate or
brake by him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is damaged, disconnect the ACC. This will
avoid possible damage. If this occurs have it
adjusted. ● Repairs to the radar sensor require special-
ist knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. Note
● If the ACC system does not work as descri-
bed in this chapter, do not use it until it has
been checked by a specialised workshop.
SEAT recommends visiting a SEAT dealership
for this purpose.
● Maximum speed with the ACC activated is
limited to 160 km/h (100 mph).
● When the ACC is switched on, strange
noises may be heard during automatic brak-
ing cause by the braking system. Messages on display, control and

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.

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

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
