(18 and 150 mph) and to select the distance
r equir
ed w
ith regard to the vehicle in front.
The ACC will adapt the vehicle's cruise speed
at all times, maintaining a safe distance with
the vehicle in front based on its speed.
When driving behind another vehicle, the
ACC function reduces speed until it is the
same as that of the vehicle ahead and main-
tains the set distance between the vehicles.
If the vehicle ahead accelerates, the adaptive
cruise control also accelerates, going no
higher than the target speed programmed.
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 distance programmed should be in-
creased when the road surface is wet.
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 216. 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 ACC does not react on approaching a
fixed o
bstacle, 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 v

ehicle continues to move involuntar-
ily after 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 i s 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. 215

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

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

Driver assistance systems
Traffic sign detection system* 1)
Intr oduction The traffic sign detection system records the
st
and
ard traffic signs in front of the vehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions.
Within its limitations, the system also dis-
plays additional signals, such as time-specif-
ic prohibitions, signs for vehicles towing trail-
ers ›››
page 246 or limitations that only apply
in the event of rain. Even on journeys without
signs, the system may display any applicable
speed limits.
In Germany, on motorways and vehicle roads,
besides speed limits and overtaking provi-
sions the system also displays the end of
prohibition signs. The valid speed limit at the
time in other countries is always shown. WARNING
The technology in the traffic sign detection
sys t

em cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience afforded by the traffic sign detection
system tempt you into taking any risks when
driving. The system is not a replacement for
driver awareness. ●
Adapt

your speed and driving style to suit
visibility, weather, road and traffic condi-
tions.
● Poor visibility, darkness, snow, rain and fog
may
lead to the system failing to display traf-
fic signs or not displaying them correctly.
● If the camera's field of vision is dirty, cov-
ered or dam
aged, system operation may be
impaired. WARNING
The driving recommendations and traffic indi-
c ation s

shown on the traffic sign detection
system may differ from the actual current
traffic situation.
● The system may not detect or correctly
show al
l the traffic signs.
● Traffic signs and traffic regulations have
priority ov
er the recommendations and dis-
plays provided by the system. Note
In order not to compromise the system's op-
eration, p l

ease take the following points 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 c o

ver the field of vision of the cam-
era.
● Always replace damaged or worn blades
when required t
o avoid lines on the camera's
field of vision.
● Check that the windscreen is not damaged
in the area of
the camera's field of vision. Note
● The u se of out

dated maps on the naviga-
tion system may cause the system to show
traffic signs incorrectly.
● In the waypoints mode of the navigation
syst
em, the traffic sign detection system is
only partly available. 1)

Advice
Engine oil Gener a
l
notesThe engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 60, Engine oil
specifications.
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6, this means that your vehicle has the LongLife
serv
ic

e programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terv
als.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 273 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 60 (up to a maximum of 0.5
litres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals, which also appear in
›››  page 60, Engine oil specifications
. In
this case, your vehicle must be serviced after
a fixed interval of 1 year/15,000 km (10,000 miles)(whatever comes first)
›››
Booklet
Maintenance Programme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 273 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 273,
Checking engine oil level and you cannot ob-
tain the oil specified for your vehicle, you can
use a small quantity of oil (once) conforming
to the VW 506 00, VW 506 01, VW 505 00,
VW 505 01 or ACEA B3/ACEA B4 specification
(up to 0.5 l).
