2017 Seat Leon 5D turn signal

Operation
at a higher speed than the inner wheel. In
thi s
w
ay, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
Multi-collision Brake
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the vehicle, as long as the accident has not dam-
aged the ESC, the br
ake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr

onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind,
especially on wet or slippery roads. If you no-
tice the systems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents! ●
Ac c

elerate with caution on slippery surfa-
ces (for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp  lights up
, or  alter-
natively, there could be a fault ››› page 119. Switching on/off the ESC and ASR

4.The clutch and the ac-
celerator are pressed at the same time.If the accelerator is pressed.
5.
If any of the tyres hasonly minimal contact
with the ground, e.g. in the case of axle articu- lation. WARNING
The smart technology incorporated into the
Auto Ho l

d function cannot defy the laws of
physics; it only works within the limits of the
system. The greater convenience provided by
the Auto Hold function should never tempt
you to take any risk that may compromise
safety.
● Never leave the vehicle running and with
the Auto Hol
d function switched on. ●
The Auto Ho l

d function cannot always keep
the vehicle stationary uphill or downhill or
stop it sufficiently, for example, on slippery
or frozen surfaces. Note
Before entering a car wash, always switch off
the Aut o Hol

d function, because if the elec-
tronic parking brake is automatically connec-
ted, it may cause damage. Cruise control system (CCS)*

ph
y
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 ››› .When the ACC halts the vehicle (e.g. traffic
j
am), the in
s

trument panel display shows the
ACC ready to start message. If the ve-
hicle ahead drives off again, the ACC will also
do so automatically.
If the vehicle ahead does not drive off again,
the vehicle can be kept indefinitely in the
ACC ready to start status by operating
the third lever repeatedly towards position 2

or b
y pressing the brake pedal.
If the Press the brake message is shown
on the instrument panel, press the brake. If
you do not, an acoustic warning will be heard
and the ACC will switch to inactive mode
(Standby). At this point, the vehicle may be-
gin to move towards the stopped vehicle
ahead ››› .
Ov er
t

aking
When the turn signal 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 218.

alised workshop. SEAT recommends vis-
iting a SEAT dealership. WARNING
If you do not heed the Press the brake
mes s

age, the vehicle may initiate an involun-
tary movement and could crash into the vehi-
cle ahead. In any event, before driving off,
check that the road is clear. The radar sensor
may not detect obstacles on the road. This
could cause an accident and serious injuries.
If necessary, apply the brake. Lane Assist system*
Intr oduction Fig. 216
In the windscreen: field of vision of
the Lane As s
i

st system camera. Using the camera located in the windscreen,
the Lane As
s
i

st system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a corrective steering movement . The purpose
is not only to warn the driver, but also to
keep the vehicle inside the lane. This move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required. Indications on the display and lamps Fig. 217

Operation
Self-deactivation: the Lane As s
i st system can
be automatically deactivated if there is a sys-
tem malfunction. The control lamp
disappears.
Hands-Off Function
● In the absence of steering wheel activity
the syst
em alerts the driver with acoustic sig-
nals and a text message on the dash panel
asking to actively take over the steering.
● If the driver does not react to this, the sys-
tem also al
erts the driver with a little shaking
motion through the brakes and, if the vehicle
has it, activates the Emergency Assist func-
tion ››› page 228.
● In vehicles without Emergency Assist, the
adaptiv
e lane guidance function will be disa-
bled after the corresponding warnings to the
driver.
The lane assist system is active but it is not
available (the control lamp is lit up yellow)
● When driving at speeds below 65 km/h (38
mph).
● When the Lane Assist system does not de-
tect the div
iding lines of the road. For exam-
ple, in the event warnings indicating road
works, and snow, dirt, moisture or reflec-
tions.
● When the radius of a curve is too small.
● When no road markings can be seen. ●
When the dist
ance to the next marking to
too great.
● When the system does not detect any clear
and active st
eering movement during a long
period of time.
● Temporarily, in the event of very dynamic
driving s
tyles.
● If a turn signal is activated.
● With the stability control system (ESC) in
Sport
mode or switched off.
Switching off the Lane Assist system in the
following situations
Due to the limits of the Lane Assist system,
switch it off in the following situations:
● When more attention is required of the
driver
● When drivin

g in a sporty style
● In unfavourable weather conditions
● On roads in poor condition
● In areas of road works WARNING
The intelligent technology in the Lane Assist
sys t

em cannot change the limits imposed by
the laws of physics and by the very nature of
the system. Careless or uncontrolled use of
the Lane Assist system may cause accidents
and injury. The system is not a replacement
for driver awareness. ●
Alw a

ys 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.
● Always keep your hands on the steering
wheel so it c
an be turned at any time.
● The Lane Assist system does not detect all
roa
d markings. The road surfaces, road struc-
tures or objects in poor condition can be in-
correctly detected as road markings under
certain circumstances by the Lane Assist sys-
tem. In such situations, switch the Lane As-
sist system off immediately.
● Please observe the indications on the in-
strument p
anel and act as is necessary.
● Always pay attention to the vehicle's sur-
roundin
gs.
● When the area of vision of the camera be-
comes
dirty, covered or is damaged, the Lane
Assist system function can be affected. CAUTION
In order to avoid influencing the operation of
the sys t

em, the following points must be tak-
en into account:
● Regularly clean the area of vision of the
camera and k
eep it in a clean state, without
snow or ice.
● Do not cover the area of vision of the cam-
era.
● Check

that the area of vision of the wind-
scr
een camera is not damaged. 226
