Operation
the other driven wheel. This function is active
up t o ap
pr
oximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: Tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, 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 brake 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
automatic

ally.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, ED S

and the electronic
torque control system cannot exceed the lim-
its imposed by the laws of physics. Always
bear this in mind, especially on wet or slip-
pery roads. If you notice the systems cutting
in, you should reduce your speed immediate-
ly to suit the road and traffic conditions. Do
not be encouraged to take risks by the pres-
ence of more safety systems. If you do, an ac-
cident 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, EDS and the elec-
tronic torque control system cannot prevent
accidents: risk of accidents!
● Accelerate 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 190

Operation
Active cylinder management (ACT ®
)*
D ependin
g 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 37.
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 braking 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
poss
ible 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
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting the engine. Avoid running the engine at high
speed.
Re
gular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature in
order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 308 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.

Operation
CAUTION
● In cer t
ain circumstances, the ultrasonic
sensors do not detect objects such as trailer
tongues, bars, fences, posts or thin trees, or
an open (or opening) rear lid, which could
damage the vehicle.
● Retrofitting of certain accessories to the ve-
hicle, s
uch as a bicycle rack, may interfere
with the operation of the Park Assist system
and cause damage.
● The Park Assist system uses as a reference
parked
vehicles, curbs and other objects.
Make sure that the tyres and wheels are not
damaged while parking. If necessary, oppor-
tunely interrupt the parking manoeuvre to
avoid damaging the vehicle.
● The ultrasound sensors on the bumper may
be damag
ed or shifted in the event of a colli-
sion, for example, when entering or exiting a
parking space.
● If you use high-pressure or vapour equip-
ment to c
lean the ultrasound sensors, do not
apply it directly unless very briefly and al-
ways from a distance of more than 10 cm.
● A registration plate or plate holder on the
front w
ith larger than the space for the regis-
tration plate, or a registration plate that is
curved or warped can cause:
–false detections,
– loss of sensor visibility.
– cancellation of the parking manoeuvre or
defective parking. ●
If one of the u

ltrasonic sensors is damaged,
the area corresponding to that group of sen-
sors (front or rear) is deactivated and cannot
be activated until the fault is corrected. How-
ever, you can still use the sensors of the oth-
er bumper as per usual. If there is a fault in
the system, consult a specialist workshop.
SEAT recommends visiting a SEAT dealership
for this. Note
● In or der t o guar

antee good system opera-
tion, keep the ultrasound sensors of the
bumper clean, free of snow or ice, and do not
cover them with adhesives or other objects.
● Certain sources of noise, such as rough as-
phalt
or paving stones and the noise of other
vehicles can induce the Park Assist system or
ParkPilot to give erroneous warnings.
● In order to become familiar with the system
and its f
unctions, SEAT recommends that you
practice operating the Park Assist system in
an area where there is not too much traffic or
in a car park. Description of the Park Assist system

Towing bracket device*
Before hitching or unhitching a trailer, always
t urn off
the anti-thef
t alarm. Otherwise, the
tilt sensor could cause the alarm to go off.
Trailers with LED rear lights
For technical reasons, trailers fitted with LED
rear lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not go off when the electrical connection with
the trailer is cut if it has rear lights with light-
emitting diodes.
If the Eco driving profile was selected when
hitching the trailer, this will automatically
switch to the Normal profile. If the system
cannot detect the attached trailer or if the
towing bracket has been retrofitted by an au-
to repair shop other than SEAT, you must
manually select the Normal profile before you
start driving with a trailer attached. To recon-
nect the Eco profile once the trailer has been
unhitched, switch the ignition off and back
on once. WARNING
If the cables are improperly or incorrectly
connect ed, it

may lead to an excessive
amount of current supplied to the trailer,
which can cause abnormalities in the entire
vehicle electronic system, as well as acci-
dents and serious injuries. ●
Ens ur

e that any repairs that need to be car-
ried out on the electrical system are carried
out by a specialised workshop.
● Never connect the trailer's electric system
directly t
o the electrical connections of the
tail lights or any other power sources. WARNING
Contact between the pins of the trailer power
soc ket

can cause short circuits, overloading
of the electrical system or failure of the light-
ing system, and consequently can cause acci-
dents and serious injuries.
● Never connect the pins of the trailer power
socket
to each other.
● Make sure any work on bent pins is carried
out by
a specialised workshop. CAUTION
Do not leave the trailer connected to the vehi-
cl e when p

arked; place it on its support
wheel or its supports. If the vehicle rises or
falls due, for example, to a variation of the
load or a burst tyre, increased pressure will
be placed on the towing bracket and the trail-
er, and both the vehicle and the trailer can be
damaged. Note
● In ca se of

malfunctioning of the electrical
systems of the vehicle or trailer, as well as of the anti-theft system, have these checked out
by
a s

pecialised workshop.
● If the trailer accessories consume energy
through the pow
er socket to the trailer and
the engine is turned off, the battery will dis-
charge.
● If the vehicle battery is running low, the
electrica
l connection with the trailer will be
automatically cut. Loading a trailer

Operation
To promote safety while driving, SEAT recom-
mend s
m
aking the most of the maximum ver-
tical load technically permissible on the cou-
pling device ››› page 273. An insufficient ver-
tical load has a negative influence on the be-
haviour of both the vehicle and trailer.
The vertical load increases the weight on the
rear axle, reducing the vehicle's carrying ca-
pacity.
Gross combination weight of the towing ve-
hicle and trailer
The gross combination weight is the actual
weight of the loaded vehicle plus the actual
weight of the loaded trailer.
In some countries trailers are classified into
distinct categories. SEAT recommends ob-
taining information from a specialised work-
shop regarding which type of trailer is most
suitable for your vehicle.
Trailer loading
The weight of the towing vehicle and trailer
must be balanced. In order to do this, the
load must be as close as possible to the max-
imum vertical load technically permissible on
the coupling point, and it must be evenly dis-
tributed between the back and front of the
trailer:
● Distribute loads in the trailer so that heavy
obj
ects are as near to the axle as possible or
above it. ●
Secure the tr
ailer load properly.
Tyre pressure
Set the tyre pressure of the trailer tyres in ac-
cordance with the trailer manufacturer's rec-
ommendations.
When towing a trailer, inflate the tyres of the
towing vehicle with the maximum allowable
pressure ››› page 308. WARNING
If the maximum permissible axle weight, the
max imum lo

ad technically permissible on the
coupling point, the maximum authorised ve-
hicle weight or the gross combination weight
of the towing vehicle and trailer are excee-
ded, accidents and serious injuries may oc-
cur.
● Never exceed the values indicated!
● The actual weight on the front and rear
axle
s must never exceed the maximum per-
missible axle weight. The weight on the front
and rear axles must never exceed the maxi-
mum permissible weight. WARNING
A shift in weight could jeopardize the stabili-
ty and sec urity

of the towing vehicle and
trailer, which could lead to accidents and se-
rious injuries.
● Always load the trailer correctly. ●
Alw a

ys secure the load properly using belts
or straps that are suitable and in good condi-
tion. Driving with a trailer
Adjusting the headlights
When to
w

ing a trailer, the front part of the ve-
hicle could lift up, and if the dipped beams
are on, this could dazzle other drivers. Use
the headlight range control to lower the cone
of light. If you do not have headlight range
control, have the headlights adjusted by a
specialised workshop.
Special characteristics of driving with a trail-
er
● If your trailer has an overru
n brake, brake
gently at first and then rapidly. This will pre-
vent the jerking that can be caused by the
locking of trailer wheels.
● Due to the gross combination weight of the
tow
ing vehicle and trailer, the braking dis-
tance increases.
● When going down a slope, go into a lower
gear (if
using a manual gearbox or the tip-
tronic automatic gearbox mode) to take ad-
vantage of the braking power provided by the
engine. Otherwise, the braking system could
overheat and even fail.

Advice
Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions such as closing
the windows and roof. If the vehicle has spe-
cial accessories such as spoilers or a roof
rack, it is advisable to consult the car wash
tunnel operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses
or seals. The same applies for the parking aid
sensors*, which are located in the rear
and/or front bumper.
Do not use a nozzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt.
Factory-fitted adhesive sheets
The following indications should be taken in-
to account to avoid damaging adhesive
sheets:
● Do not use high pressure cleaners. ●
Do not use s crapers to remove ice or snow
from the sheets.
● Do not polish the adhesive sheets.
● Do not use dirty cloths or sponges.
● It is preferable to wash them with a soft
spong
e and gentle neutral soap.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
You should start on the roof and work down.
Special car soap should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The v ehic

le should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of
wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts. ●
When wa shin

g the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wa

sh the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
spong
es or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlight
s at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do
not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out
in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wa
sh, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Bef or

e washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen: 286

Advice

ab
its will increase the useful life of your
tyres.
● Check tyre pressure at least once a month,
and also prior to an
y long trip.
● The tyre pressure should only be checked
when the tyre
s are cold. Do not reduce the
pressure of warm tyres.
● Adjust tyre pressure to the load being car-
ried by the
vehicle. ●
In vehic
les with a tyre pressure indicator,
save the modified pressure of tyres
››› page 311, ››› page 308.
● Avoid fast cornering and hard acceleration.
● Inspect the tyres for irregular wear from
time to time.
The usef

ul life of your tyres depends on the
following factors:
Tyre pressure
The tyre inflation pressures are listed on a
sticker on the rear of the front left door frame
››› Fig. 242.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (tyre pressure ). When driving
with comfort tyre pressure fuel consumption
may increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to the max-
imum value indicated on the sticker
››› Fig. 242.
Do not forget the spare wheel when checking
the tyre pressures: Keep this spare wheel in- flated to the highest pressure required for the
roa

d wheels.
In the case of a minimised temporary spare
wheel (125/70 R18) inflate to a pressure of
4.2 bar as indicated on the tyre pressure la-
bel ››› Fig. 242.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Offi-
cial Service.

Wheels
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. 243
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. Interchanging tyres

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. 244. 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. »

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 319.
● 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. 311

ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to mor
e flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control. ●
Ty r

e pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not hav
e to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING

in Warning
and contr o
l lamps on page 119. Note
● If e x

cessively low tyre pressure is detected
with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.
● Driving on dirt tracks for a long period of
time or driving in a s
porty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change. 312
