2016 Seat Leon 5D stop start

Driver assistance systems
If the vehicle is equipped with automatic
g e
arbo
x, 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
››› page 198. WARNING
The intelligent technology in the ACC cannot
ov er

come 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
vehicl
e 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 r
oads, 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 unpav
ed roads. The ACC has been de-
signed for use on paved roads only. ●
The AC C

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 only reacts to people if a pedes-
trian monitorin
g system is available. In addi-
tion, the system does not react to animals or
vehicles crossing your path or approaching
head-on down the same lane.
● If the ACC does not reduce speed sufficient-
ly, brak
e 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 af
ter a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driv
er interven-
tion prompt, adjust the distance yourself.
● The driver should be ready to accelerate or
brake b
y him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged, 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 A C

C 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 210 km/h (150 mph).
● When the A

CC is switched on, strange
noises
may be heard during automatic brak-
ing cause by the braking system. 197

Adjusting distance level
The distance according to speed with regard
to the vehicle in front can be controlled on
the Easy Connect system on 5 levels
›››  page 27.
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
You can u
se the Easy Connect system to ad-
just the level of distance that should be ad-
justed when the ACC is switched on with the  button and the

Adjusting the driving programme
In vehicles with driving profile selection
(SEAT Drive Profile), the profile selected can
influence acceleration behaviour
››› page 219. The following driving programmes items can
be selected:
● Norm

al
● Sport
● Eco
In vehic
les without the driving profile selec-
tion function, acceleration behaviour can be
influenced by selecting a driving programme
on the Easy Connect system using the  button and the
S
ETUP and
Driv

 page 27.
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 sev

eral brake lights of the vehicle or elec-
trically
connected trailer are damaged.
● If the vehicle is reversing.
● Driving faster than 210 km/h (150 mph). WARNING
There is a danger of rear collision when the
minimum dis t

ance 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 brak
e ped

al should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions pr
operly.
● “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 ob
ligatory minimum distances be-
tween vehicles. Note
● The progr ammed s

peed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivat
ed during acceleration or else the
ESC is activated in Sport* Mode
( ››› page 110), the ACC switches off automati-
cally.
● In vehicles with the Start-Stop system, the

ph

s

ical limitations inherent in the system.
For example, certain reactions of the ACC, in
certain circumstances, may be unexpected or
come late from the driver's point of view. So
pay attention in order to intervene if necessa-
ry.
For example, the following traffic situations
call for the utmost attention:
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 sign

al 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 200.
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. 205 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 200.
Driving in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels. »

Traffic Jam Assist is an additional function of
Lane Assist ››› page 213 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ››› page 196. Therefore, it is essential
that you read these two chapters carefully
and note the limitations of the systems and
the information about them.
Operation of Traffic Jam Assist
At speeds of below 60 km/h (40 mph), Traffic
Jam Assist can maintain a (temporary) dis-
tance preset by the driver with respect to the
vehicle ahead and help stay within the lane

T o do thi
s, the sy

stem automatically controls
the acceleration, brakes and steering, and
slows down the vehicle until it stops fully
when behind another vehicle that is stop-
ping. It then automatically moves off again

Introduction 

›› ›

table on page 2
SEAT Drive Profile enables the driver to
choose between four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
In the FR and X-PERIENCE models equipped
with dynamic chassis control, the Comfort
profile is also available.
In the Leon Cupra model the four profiles are Comfort , Sport, Cupra and Individual .
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed. Description Depending on the equipment fitted in the ve-
hicl
e,

SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when Eco mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco 1)
mode activates the In-
ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles, Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)

››› table on page 2 DCC continuously adapts the shock absorb-
ers
t

o the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting .
Address
Power steering becomes more robust in Sport mode to enable a sportier driving
style. In the Leon Cupra the power steering
becomes more robust in Cupra mode.

vent it from functioning.
● At speeds below 65 km/h (40 mph)
● 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
driver Fatigue det

ection will be restored when the
vehicl
e 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-
ted.
