with rear cross traffic alert will be automati-
cally deactivated when, among other rea-
sons, one of the sensors is detected to be
permanently covered. This may be the case if,
for example, there is a layer of snow or ice in
front of one of the sensors.
The relevant text message will appear in the
dash panel display.
Trailer mode
The Blind spot detector and the rear cross
traffic alert will be automatically deactivated
and it will be impossible to activate them if
the tow hitch is electrically connected to a
trailer or other similar object.
As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message will appear on the instrument panel
display indicating that the blind spot detec-
tor and the rear cross traffic alert are deacti-
vated. Once the trailer has been unhitched
from the vehicle, if you want to use the blind
spot detector and the rear cross traffic alert,
you will have to reactivate them in the corre-
sponding menu.
If the towing hitch is not factory equipped,
then the blind spot detector and the rear
cross traffic alert will have to be deactivated
manually when driving with a trailer. SEAT Drive Profile*
Introduction SEAT Drive Profile enables the driver to
choo
se betw

een four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hic
l
e,

SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when Eco mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges. »

Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 257.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 291, Technical
specifications.
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
The maximum permissible tyre pressure val-
ues are shown on the sticker on the rear part
of the left front door frame. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 255.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 255. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 254

Care and maintenance
Steel wheel rims –
Clean steel wheel rims regularly using a
separ at
e sponge.
Use an industrial cleaner to remove brake
dust. Any damage to the paint on steel wheel
rims should be repaired before starting to
rust. WARNING
● Never w a

sh tyres with a cylindrical jet. Even
at large spraying distances and short clean-
ing times, damage can occur to the tyres.
This may cause an accident.
● Water, ice and salt on the brake system can
reduce br
aking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking. “Dry” the brakes by brak-
ing several times ››› page 179, Braking ca-
pacity and braking distance .Alloy wheel rims
Every two weeks
– Wash salt and brake dust from alloy
wheel s.
– Use an ac

id free detergent to clean the
wheel rims.
Ev

ery 3 months
– Apply a hard wax compound to the wheels. Alloy wheels require regular attention to pre-
serve their ap

pearance. If road salt and brake
dust are not often removed, the aluminium
finish will be impaired.
Always use an acid-free detergent for alloy
wheel rims.
Car polish or other abrasive agents should
not be used for maintaining the rims. If the
protective coating is damaged, e.g. by flying
stones, the damaged area should be re-
paired immediately. WARNING
Observe the safety warnings ›››
in Steel
wheel rims on p
age 265. Vehicle underbody protection
The vehicle underbody is coated to protect it
fr
om c
hemic

al and mechanical damage.
The protective coating can be damaged when
driving. We recommend that you check the
protective coating under the body and on the
running gear, and retouch it if necessary, be-
fore and after the winter season.
We recommend that you go to your Technical
Service to carry out repair work and addition-
al anti-corrosion work. WARNING
Do not apply underseal or anti-corrosion
co atin

gs to the exhaust pipes, catalytic con-
verter or the heat shields on the exhaust sys-
tem. The heat of the exhaust system or the
engine could cause them to ignite. Risk of
fire. Cleaning engine compartment
Take special care when cleaning the engine
comp
ar

tment.
Anti-corrosion treatment
The engine compartment and the surface of
the power unit are given anti-corrosion treat-
ment at the factory.
Good corrosion protection is particularly im-
portant in winter when the vehicle is fre-
quently driven on salted roads. To prevent
the salt corroding the vehicle, the entire en-
gine compartment should be thoroughly
cleaned before and after winter.
Technical Services have the proper products
for cleaning and preservation as well as the
necessary workshop equipment. For this rea-
son, we recommend having this work per-
formed by them.
The anti-corrosion protection is usually re-
moved if the engine compartment is cleaned
with grease removing solutions, or if you »

If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
tank is “full”. Never attempt to fill beyond
this point, as this will fill the expansion
chamber. Fuel may leak out if ambient condi-
tions are warm.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. WARNING
● Fuel i

s highly flammable and can cause se-
rious burns and other injuries.
–Never smoke or come into contact with
sparks when filling the fuel tank of the
vehicle or a spare fuel canister with fuel.
This is an explosion hazard.
– Follow legal requirements for the use of
spare fuel canisters.
– For safety reasons we do not recommend
carrying a spare fuel canister in the vehi-
cle. The canister could be damaged in an
accident and leak. ●
If, in e x

ceptional circumstances, you have
to carry a spare fuel canister, please observe
the following:
–Never fill the spare fuel canister inside
the vehicle or on it. An electrostatic
charge could build up during filling, caus-
ing the fuel fumes to ignite. This could
cause an explosion. Always place the
canister on the ground to fill it.
– Insert the fuel nozzle into the mouth of
the canister as far as possible.
– If the spare fuel canister is made of met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic charge
building up.
– Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapours are
explosive. Danger of death. CAUTION
● Fuel s

pills should be removed from the
paintwork immediately.
● Never run the tank completely dry. Irregular
fuel s
upply can cause misfiring. As a result,
unburnt fuel could enter the catalytic convert-
er and cause damage.
● When filling the fuel tank after having run it
compl
etely dry on a vehicle with a diesel en-
gine the ignition must be switched on for at
least 30 seconds before starting the engine.
Subsequently, when you start the engine it
may take longer than normal to start firing (up to one minute). This is due to the fact that
the fuel
sy

stem has to purge itself of air be-
fore starting. For the sake of the environment
Do not try to put in more fuel after the auto-
m atic fi

ller nozzle has switched off, this may
cause the fuel to overflow if it becomes warm. Note
There is no emergency mechanism for the
manua l

release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Fuel
Ty
pe

s of petrol The correct grade of petrol is listed inside the
f
uel
t

ank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON). »

Checking and refilling levels
We recommend the use of diesel
f uel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel). CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. AdBlue
®
Inf orm
ation on AdBlue ® The consumption of AdBlue
®
depends on
y
our personal driving style, the temperature
of the system and on the outdoor tempera-
ture when the vehicle is used.
AdBlue ®
freezes at temperatures of -11°C
(+13°F). The system has heating elements
that guarantee its operation even at low tem-
peratures.
The AdBlue ®
tank level capacity is approxi-
mately 10.4 litres.
The AdBlue ®
tank should never be empty.
When the distance to empty drops below
2400 km, a warning to refill the AdBlue ®
tank
will appear on the dash panel display
››› page 271. If this information is ignored,
later on it will not be possible to re-start the
engine. If this warning does not appear, it is
not necessary to refill the AdBlue ®
tank.
AdBlue ®
is a registered brand of the German
Association of the Automotive Industry (VDA)
and is also known as AUS32 or DEF (Diesel
Exhaust Fluid). CAUTION

If a warning message about AdBlue ®
levels
appears on the dash panel display, fill at
least the minimum amount required (approx.
5 litres). Only after adding this amount will
the system detect that AdBlue ®

page 274.
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service fluids and consumables replaced by a Techni-
cal

Service. Please observe the relevant in-
structions ››› page 259. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.

g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coo
lant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● App

ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
 page 72.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off

● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
