g Fuel consumption, environmental pollution
and we
ar t

o the engine, brakes and tyres de-
pends largely on driving style. Fuel consump-
tion can be reduced by 10-15% with an eco-
nomical driving style and proper anticipation
of traffic conditions. The following section
gives you some tips on lessening the impact
on the environment and reducing your oper-
ating costs at the same time.
Active cylinder management (ACT ®
)*

››› table on page 2
Depending on vehicle equipment, the active
cylinder management (ACT ®
) may automati-
cally deactivate some of the engine cylinders
if the driving situation does not require too
much power. When it is switched off, no fuel
is injected into these cylinders, hence total
fuel consumption may be reduced. The num-
ber of active cylinders can be seen on the in-
strument panel display ›››
 page 31.
Foresight when driving
Acceleration causes the vehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic lights are red). This takes advantage of the
engine br
ak

ing effect, reducing wear on the
brakes and tyres. Emissions and fuel con-
sumption will drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear. Running the engine at
high rpm in the lower gears uses an unneces-
sary amount of fuel.
Manual gearbox : shift up from first to second
gear as soon as possible. In any case, we rec-
ommend that you change to a higher gear
upon reaching 2,000 rpm. Choosing the right
gear enables fuel savings. Select the highest
possible gear appropriate for the driving sit-
uation (the engine should continue function-
ing with cyclical regularity).
Automatic gearbox : accelerate gradually and
without reaching the “kick-down” position.
Avoid driving at high speed
Avoid travelling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling
is automatically reduced. In vehicles without

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.

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

table on page 2 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. Note
● The Lane Ass i

st system has been exclusive-
ly developed for driving on paved roads only.
● If the Lane Assist system does not work as
desc
ribed in this chapter, do not use it and
contact a specialised workshop.
● If there is a fault in the system, have it

Operation Fig. 214
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 . 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.
Steering wheel vibration
The following situations can cause vibration
in the steering wheel and require the driver
to take active control of driving:
● When the limits of the very nature of the
syst
em are reached. ●
When the maximum r
otational torque dur-
ing the corrective steering movement is not
enough to keep the vehicle inside the lane.
● When no lane is detected during the correc-
tive st
eering movement.

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 217.
● 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)

CAUTION
● Some v ehic
les, for example those with the
Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tached t
o the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage.
● The battery holder and clamps must always
be correctly
secured.
● Before starting any work on the battery, al-
way
s observe the warnings listed under
››› page 269, Important safety warnings for
handling a vehicle battery .
● Do not forget to replace the battery cover-
ings, wher
e applicable. It is a protection for
high temperatures. This in turn extends the
vehicle service life. For the sake of the environment
 Batteries contain toxic substances includ-
in g s

ulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.
Make sure disconnected batteries cannot tip

Wheel s
and ty

res
General notes –
When driving with new tyr e
s, be especially
careful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obs

tacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
dam ag

ed (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
plac

ed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
poss

ible.
– Mark the wheels before taking them off so
that they

rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be stor

ed in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
away and should therefore be “run in” by driving carefully and at moderate speeds for
about the firs

t 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

WARNING
● Alw a
ys adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the v
ehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicators
Fig. 244
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
w
orn. The origin
al
tyres on your vehicle have
1.6 mm high “trea
d wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.) WARNING
The tyres must be replaced at the latest when
the tre a

d is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
such a
s wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
trea
d depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
● The speed has to be adapted accordingly,
otherwi
se there is a risk of losing control over
the vehicle. Changing wheels
Fig. 245
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheel
s
shou

ld be changed round from
time to time according to the system
››› Fig. 245. The useful life of all the tyres will
then be about the same time.
New tyres or new wheels –
All four wheels must be fitted with tyres of
the s ame type, s
iz

e (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not individual

ly (i.e. both front tyres or
both rear tyres together).
– Do not use tyres whose effective size ex-
ceeds

the dimensions of the factory-ap-
proved makes of tyre. »

nning the vehicle on tyres that are
more than 6 years old. If you have no
alternative, you should drive slowly and with
extra care at all times.
● If wheel trims are fitted after the car is pur-
cha
sed, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l aw

s in the country concerned. Note
● A S EA

T Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their “pr
evious history”.
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
ma y

lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the ty
res are cold at all times
››› page 283.
● Regularly check the cold inflation pressure
of the tyr
es. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re gu

larly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on s

umption and tyre wear. Note
● Driv ing f

or the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by
SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Re
gularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 275
