Safety Description and operation
Traffic Jam Assist helps the driver keep the
car w
ithin its

lane and to move in convoy in
case of traffic congestion or slow traffic.
Traffic Jam Assist is an additional function of
Lane Assist ››› page 224 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ››› page 214. 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 accelerator, brakes and steering, and
slows the vehicle, stopping it fully if neces-
sary, when faced with a vehicle in front that
has stopped. It automatically moves off again
when the vehicle ahead moves.
Traffic Jam Assist is designed only for use on
motorways and wide roads. Therefore, never
use it in city traffic. Technical requirements for using Traffic Jam

Operation
● When mor e att
ention i
s required by the
driver.
● When driving in a very sporty style.
● In adverse weather conditions, e.g. in case
of sno
w or heavy rain.
● When driving on roads in poor condition.
● In sections with roadworks.
● In city journeys. WARNING
The smart technology incorporated into Traf-
fic Jam As s

ist cannot defy the laws of phys-
ics; it only works within the limits of the sys-
tem. Accidents and severe injury may occur if
Traffic Jam Assist is used negligently or invol-
untarily. The system is not a replacement for
driver awareness.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit the
visibility, weather, road and traffic condi-
tions.
● Do not use Traffic Jam Assist in city jour-
neys.
● Do not u

se Traffic Jam Assist if there is poor
vis
ibility, for example, in case of snow, ice,
rain or loose gravel, or on steep or slippery
sections or flooded roads.
● Do not use Traffic Jam Assist offroad or on
roa
ds where the surface is not firm. Traffic
Jam Assist has been designed for use on
paved roads only. ●
Traffic

Jam Assist does not react to people
or animals or vehicles crossing your path or
that approach you head-on down the same
lane.
● If Traffic Jam Assist does not reduce speed
sufficiently
, brake the vehicle immediately by
applying the pedal.
● If the vehicle continues to move when you
wish it
to stop after a driver intervention
prompt, brake the vehicle by applying the
pedal.
● If driver intervention is requested on the
da
sh panel display, immediately resume con-
trol of the vehicle.
● Keep your hands on the wheel at all times
to be re
ady to intervene in the steering at any
time. The driver is always responsible for
keeping the vehicle in its own lane.
● Always be prepared to take charge of driv-
ing (acc
elerating or braking) yourself. Note
● If T

raffic Jam Assist does not work as de-
scribed in this chapter, stop using it and con-
tact a specialised workshop.
● If the system is faulty, take it to a special-
ised work
shop and have it checked. Emergency Assist
D e
s

cription and operation Emergency Assist detects whether there is in-
activity
b

y the driver and can automatically
keep the car within the lane and stop it alto-
gether if necessary. This way the system can
actively help avoid an accident.
Emergency Assist is an additional function of
Lane Assist ››› page 224 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ›››
page 214. 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 Emergency Assist
Emergency Assist detects when the driver
ceases to perform any activity and repeatedly
requests that he/she regain active control of
the vehicle, through the use of optical and
acoustic warnings and by applying the
brakes.
If the driver continues to do nothing, the sys-
tem automatically takes over the accelerator,
brakes and steering in order to brake the ve-
hicle and keep it in its lane ››› . When the
Emer g
ency

Assist is actively adjusting, the
hazard warning lights come on ›››
page 145
and the vehicle makes slight zigzag move-
ments in the lane in order to warn other driv-
ers.

Driver assistance systems
If the remaining braking distance is suffi-
c ient, if
nec
essary the system slows down the
vehicle until it stops completely and auto-
matically switches on the electronic parking
brake ››› page 183.
Switching the Emergency Assist on and off
The Emergency Assist is switched on auto-
matically when the Lane Assist is switched on
››› page 224.
Technical requirements for using the Emer-
gency Assist
● The adaptive cruise control (ACC) must be
switc
hed on ››› page 214.
● The Lane Assist must be switched on
›››
page 224.
● The selector lever must be in the D/S posi-
tion or in the
Tiptronic selector gate.
● The system must have detected a lane sep-
aration line on both side
s of the vehicle
››› Fig. 218.
The following conditions may cause the
Emergency Assist not to react or to switch off
automatically:
● If the driver accelerates, brakes or moves
the steerin
g wheel.
● If any of the conditions mentioned in
›››
page 229, Technical requirements for us-
ing the Emergency Assist are not fulfilled.●
If any
of the conditions required for opera-
tion of the Lane Assist are not met
››› page 224.
● If any of the conditions necessary for the
adaptiv
e cruise control (ACC) to work are no
longer fulfilled ››› page 214. WARNING
The smart technology incorporated into the
Emerg ency

Assist cannot overcome the limits
imposed by the laws of physics; it only works
within the limits of the system. The driver is
responsible for driving the vehicle.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit the
visibility, weather, road and traffic condi-
tions.
● Keep your hands on the wheel at all times
to be re
ady to intervene in the steering at any
time.
● The Emergency Assist alone cannot always
avoid acc
idents or serious injuries.
● If the operation of the Emergency Assist is
impaired, f
or example if the radar sensor of
the adaptive cruise control (ACC) or the Lane
Assist camera are covered or have lost their
settings, the system may intervene inoppor-
tunely in braking or in steering.
● The Emergency Assist does not react to
people or anim
al or vehicles crossing your
path or which approach you head-on in the
same lane. WARNING
If the Emergency Assist Intervenes inoppor-
tu nely

, serious accidents and injuries may oc-
cur.
● If the Emergency Assist does not operate
properly, sw
itch off the Lane Assist
››› page 224. Doing so will also switch off the
Emergency Assist.
● Have the system checked by a specialised
workshop
. SEAT recommends visiting a SEAT
dealership for this. Note
● Autom atic

interventions by the Emergency
Assist on the brakes may be interrupted by
pressing the accelerator or brake or by mov-
ing the wheel.
● Hazard warning lights that come on auto-
matica
lly can be switched off by pressing the
accelerator or the break, moving the steering
wheel or pressing the hazard warning light
switch.
● If this occurs, the Emergency Assist may
deceler
ate the vehicle until it comes to a com-
plete stop.
● When the Emergency Assist is activated, it
is on
ly available again after the ignition has
been switched off and back on again. 229

provisions can be adjusted. The speed is ad-
justed in steps of 10 km/h (5 mph) within a
range of between 60 km/h (40 mph) and
130 km/h (80 mph). If it is adjusted to a
speed greater than that which is permitted in
the country in question for driving with a
trailer, the system automatically displays the
usual speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits
as if there were no trailer hitched. Limited operation
The traffic s

ign detection system has certain
limitations. The following cases may lead the
system to operate with limitations or not at
all:
● In the case of poor visibility, e.g. in snow,
rain, fog or int
ense mist.
● In cases of dazzling, e.g. caused by head-
on traffic or b
y the sun.
● When driving at high speeds.
● If the camera is covered or dirty.
● If the traffic signs are out of the camera's
field of
vision.
● If the traffic signs are partially or totally
cov
ered, e.g. by trees, snow, dirt or other ve-
hicles.
● In the case of traffic signs that do not fulfil
the regu
lations.
● In the case of damaged or bent traffic
signs.
● In the c

ase of variable messages on over-
head or g
antry signs (LED-based variable traf-
fic signs or other lighting units).
● If the maps on the navigation system are
not up-to-d
ate.
● In the case of adhesives affixed to vehicles

Operation
●
The knock s
or damage on the radiator
grille, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In c ert

ain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g:
–with rough or cobbled floors or ground
with long grass;
– with external ultrasound sources, such as
cleaning vehicles or other vehicles;
– In downpours, intense snow or dense ex-
haust gases;
– if the registration plate (front or rear) is
not properly affixed to the bumper sur-
face;
– or in locations such as the brow of a hill.
● In order to guarantee good system opera-
tion, keep the ultr
asound sensors clean, free
of snow or ice, and do not cover them with
adhesives or other objects.
● If you use high-pressure or vapour equip-
ment to c
lean the ultrasound sensors, apply
it directly only very briefly and always from a
distance of more than 10 cm.
● Retrofitting of accessories to the vehicle,
such a
s a bicycle rack, may interfere with the
operation of the Parking Aid. ●
In order t o f

amiliarise yourself with the sys-
tem, it is advised that you practice parking in
an area or car park that is free from traffic.
There must be good weather and light condi-
tions.
● The volume and tone of the warnings can
be modified, in addition t
o the indications
››› page 241.
● In vehicles without a driv
er information
system, these parameters can be modified in
a SEAT Official Service or in a specialised
workshop.
● Please observe information on towing a
trail
er ››› page 242.
● The display on the Easy Connect screen
shows
a slight time delay. Rear parking aid*
The rear Parking Aid assists the driver in

sounds.
Description
There are sensors integrated in the rear
bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings.
Make particularly sure that the sensors are
not covered by adhesives, residues and the
like, as this could affect the system's opera-
tion. Cleaning instructions ››› page 259. The approximate measurement range of the
rear sen

sors is:
side area0.60 m
central area1.60 m As you approach the obstacle, the time inter-
val
betw

een the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: Do not continue to
move forward (or backward) ››› in General
inform ation on p

age 237, ››› in General in-
form ation on p
age 237 !
If you maintain separation from the obstacle,
the volume of the warning begins to reduce
after four seconds (does not affect the tone
of the constant warning).
Activating/Deactivating
When engaging reverse gear, the parking aid
is automatically switched on. This is con-
firmed with a short warning.
On disengaging reverse gear, the Parking Aid
system is disconnected immediately.
