Operation
Catalytic converter 3 Applies to vehicles with petrol engine
The v
ehicle must only be used with unleaded
petrol, otherwise the catalytic converter will
be irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter 3 App
lies to vehicles with diesel engine
The die
sel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear (automatic gearbox: gear S). Maintain the en-
gine speed at
ap

proximately 2,000 rpm. The
rise in temperature causes the soot on the fil-
ter to burn. On completion of the cleaning
the warning lamp will switch off. If the warn-
ing lamp does not switch off, go immediately
to a specialised workshop to rectify the prob-
lem.
Engine management*  This warning lamp monitors the engine man-
ag
ement
sy

stem for petrol engines.
The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi-
cle to a specialised workshop as soon as
possible and have the engine checked.
Emission control system*  Control lamp

she
s:
When there is misfiring that can damage the
catalytic converter. Reduce speed and drive
carefully to the nearest specialised workshop
to have the engine checked. The control lamp
 lights up:
If
a fault has developed during driving which
has reduced the quality of the exhaust gas
(e.g. lambda probe fault). Reduce speed and

Driving tips Driv in
g thr
ough flooded roadsTo prevent damage to the vehicle when driv-
ing thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edg
e of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc ., the br

aking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, running gear or electrical
system.
● Whenever driving through water, the Start-
Stop sys
tem* must be switched off
››› page 191. Note
● Check the depth of

the water before enter-
ing the flooded zone. ●
Do not s t

op in the water, drive in reverse, or
stop the engine in any situation.
● Note that vehicles travelling in the opposite
direction ma
y splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). Driver assistance systems

table on page 2
The Start-Stop system helps save fuel and re-
duce CO 2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fas-
tened.
● The bonnet mu

st be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) sinc
e the last stop.
● The vehicle cannot be towing a trailer. »

Operation
WARNING
● Never sw it
ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop sys
tem is switched off when working in
the engine compartment ››› page 193. CAUTION
The Start-Stop system must always be
swit c

hed off when driving through flooded
areas ››› page 193. Stopping/Starting the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutr al
and r

elease the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play. –
When the clutc
h pedal is pressed the en-
gine will start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and k

eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
display.
– When you take your foot off the brake pedal
the engine wi

ll start up again. The warning
lamp will switch off.
Additional information related to the auto-
matic gearbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R. Note
● You c an c

ontrol 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 stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes
The system can interrupt the Start-Stop mode
fr
equently
f

or 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 switch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required t
emperature for the Start-Stop
mode.

Fig. 195 button
remains on when the Auto Hold function is
connected.
Once connected, the Auto Hold function as-
sists the driver in keeping the vehicle station-
ary at repeated intervals or for a certain peri-
od of time with the engine running, for exam-
ple, when going up a slope, when stopped at
traffic lights or in heavy traffic with intermit-
tent stops.
When connected, the Auto Hold function au-
tomatically prevents the vehicle from rolling
when stationary without pressing the brake
pedal. After detecting that the vehicle is stationary
and the brake ped

al has been released, the
Auto Hold function holds the vehicle. The
driver can lift their foot off the brake pedal.
When the driver touches the accelerator ped-
al or accelerates slightly to continue driving,
the Auto Hold function releases the brake.
The vehicle moves according to the slope of
the road.
If the vehicle is stationary and one of the con-
ditions required by the Auto Hold function is
impaired, it disconnects itself and the but-
ton's control light goes out ››› Fig. 195. The
electronic parking brake connects automati-
cally, if necessary, to park the vehicle safe-
ly ››› .
C ondition
s

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

ermine the tr
affic situation
››› Fig. 199 1 . This sensor can detect vehi-
c l
e

s in front up to a distance of approximately
120 m.
The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
adaptive cruise control (ACC) does not work.
The instrument panel displays the following
message: ACC: No sensor vision! If
necessary clean the radar sensor ››› .
When the r a
d

ar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again. ACC operation may be affected by a strong ra-
dar rev

erse 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 d

amaged 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 settin
gs when knocked, for example, dur- ing a parking manoeuvre. This may compro-
mise the sy
s

tem'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 pref
erably with a solvent-free de-icer
spray. 199

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!
