Driving through water. To prevent the vehicle from being damaged
when driv
in
g thr

ough water (i.e. flooded
roads), please observe the following:
● Determine the depth of the water before
entering.
Water can reach a maximum height
of below the door sill ››› Fig. 181.
● Drive at a maximum pace of walking speed.
Driving at
a higher speed can cause a wave
in front of the vehicle, which can cause water
to enter the engine air intake system or other
parts of the vehicle.
● Never stop in the water, never reverse and
never st
op the engine.
● Before driving through water deactivate the

g beh

aviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Fatigue
detection sy s

tem tempt you into taking any
risks when driving. Take regular breaks, suffi-
cient in length when making long journeys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of
the driver in al
l circumstances. Consult the in-
formation in the section ››› page 186, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-

Towing bracket device
Trailer weight Trailer weight
The comb
ined
vehicle and trailer must be
balanced. To do so use the maximum permit-
ted towing bracket load. An insufficient
weight exerted by the trailer drawbar on the
ball joint of the towing bracket will have a
negative impact upon the response of the ve-
hicle-trailer assembly on the road.
Weight distribution
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Ensure that the objects do not move.
If the towing vehicle is empty and the trailer
loaded then the load distribution is incorrect.
However, if these conditions cannot be avoi-
ded, drive very slowly.
Tyre pressure values
Correct the tyre pressure in your vehicle to
“total load” ›››
page 218, Service life of
tyres.
Trailer weight
Never exceed the authorised trailer weight
under any circumstances ›››
page 223, Tech-
nical specifications .
The trailer weights listed are only applicable
for altitudes up to 1000 m above sea level.
Due to lower air density, engine power de- creases depending on the increase in alti-
tude, thi
s

also reduces climbing ability,
which requires a reduction of the weight of
the vehicle with a trailer by 10% for every
1000 m increase in altitude. The weight of
the assembly is calculated by adding the ve-
hicle weight (loaded) to the trailer weight
(loaded). Always drive with special care when
towing a trailer.
The towed load and support load information
that is displayed on the towing bracket man-
ufacturers label are only values for the verifi-
cation of the device. The correct figures for
your specific vehicle, which are usually lower
than these figures, are given in the documen-
tation of your vehicle. WARNING
● Exc eedin

g the maximum established load
per axle and the maximum towing bracket
load in addition to the maximum permitted
load or the load of the vehicle + trailer as-
sembly can cause accidents and serious inju-
ries.
● A sliding load can considerably affect the
stab
ility and safety of the vehicle + trailer as-
sembly, resulting in accidents and serious in-
juries. Driving with a trailer
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.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 122, Headlight
range control.
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.

The trailer is incorporated into the vehicle's
anti-theft alarm system:
● When the vehicle has a factory-fitted anti-
theft al
arm and a towing bracket.
● When the trailer is electrically connected to
the vehic
le via the towing bracket socket.
● When the vehicle electrical device and the
tow
ing bracket are operational.
● When the vehicle is locked and the vehi-
cle's
anti-theft alarm device is activated.
Once the electrical connection is interrupted
with the vehicle trailer locked, the alarm
sounds.
Always switch off the vehicle anti-theft alarm
device before connecting or disconnecting a
trailer. The vehicle anti-theft alarm device
could cause the alarm to sound ››› page 116,
Anti-theft alarm*.
Engine overheating
In the event that the coolant temperature
gauge needle moves to the right section of
the scale or to the red area, immediately re-
duce speed. If the control lamp  flashes on
the general instrument panel, stop the vehi-
cle and switch off the engine. Wait several
minutes and check the coolant level in the
tank ››› page 210. Please observe the following indications
›››
page 210, Control lamp .
The coolant temperature can be reduced by
switching on the heating. WARNING
● Adjus t

your speed to suit the road and traf-
fic conditions.
● An electrical installation that is connected
incorrectly
or by non-specialised personnel
can prevent the connection of the current to
the trailer and cause faults in the operation of
the electrical system throughout the entire
vehicle, leading to accidents and serious in-
jury.
● All electrical work must be carried out only
by s
pecialised services.
● Never directly connect the trailer electrical
device t
o the electrical sockets of the reverse
driving lights or other sources of electrical
current. CAUTION
● Av oid c

orners, and sudden and sharp brak-
ing.
● Once the trailing arm has been removed,
plac
e the corresponding cover on the hole of
the fastening point. This prevents dirt from
entering the hole – see the trailer system as-
sembly manual. Note
● In the event of

frequent journeys with a
trailer, we recommend also having the vehi-
cle inspected in between the service inter-
vals.
● When connecting and disconnecting the
trail
er, the handbrake must be applied.
● For technical reasons, trailers with LED re-
verse light
s cannot be incorporated into the
vehicle anti-theft alarm system. Towing bracket device
Intr oduction If the vehicle is equipped with a towing
br
ac
k

et device from the factory or is a genu-
ine SEAT accessory, it meets all national tech-
nical and legal requirements for towing.
Your vehicle is fitted with a 13-pin power
socket for the electrical connection between
the trailer and the vehicle. If the trailer is
equipped with a 7-pin connector, you can
use the corresponding adaptor, which is
available as a genuine SEAT accessory.
The towing device has a maximum vertical
load of 50 kg.

Care and maintenance
Wheels Wheel trims
If
y
ou wash the vehicle regularly, you should
also thoroughly wash the wheel trim. Regu-
larly remove any brake dust and road salt
from the wheels, otherwise the wheel materi-
al could be damaged. Repair any damage to
the wheel paintwork immediately.
Alloy wheels
After thorough washing, treat the wheels
with a protective product for alloy wheels. Do
not use abrasive products to care for the
wheels. WARNING
Moisture, ice and road salt may affect braking
efficiency . Ri

sk of accident! CAUTION
Heavy dirt on the wheels could lead to their
mis a

lignment. This could result in vibrations
being transmitted to the steering wheel that
under certain conditions may cause prema-
ture steering wear. This dirt must be re-
moved. Note
We recommend you leave paint damage re-
pair s

to a SEAT Authorised Service. Vehicle underbody protection
The underside of the vehicle is coated to per-
manently
pr

otect it from chemical and me-
chanical agents.
Given that damage to the protective coating
during driving cannot be completely ruled
out, we recommend you check the condition
of the protective coating on the underbody
and suspension at regular intervals, prefera-
bly before the start and end of the coldest
season of the year.
Authorised SEAT dealers have suitable spe-
cial products and the necessary facilities and
are aware of the techniques required for their
application. We therefore recommend all
touch-up work or additional anti-corrosion
measures be performed by an authorised
SEAT dealer. WARNING
Do not apply underseal or anti-corrosion
co atin

gs to the exhaust pipes, catalytic con-
verter, particulate filter or heat shields on the
exhaust system. Once the engine has
reached operating temperature, these sub-
stances could catch fire. Risk of fire! Cavity waxing
All cavities on the vehicle exposed to corro-
sion ar
e perm

anently factory-protected by a
wax solution .
This wax solution does not need to be
checked or touched up. Should wax run out
of the cavities at high ambient temperatures,
remove it using a plastic scraper and clean
away any stains using lighter fluid. WARNING
Note the regulations concerning safety and
env ir

onmental protection if you use lighter
fluid to remove the wax. Risk of fire! Leatherette and upholstery
Leatherette can be cleaned with a damp
c
loth. If
thi

s is not sufficient, these parts
should only be cleaned with solvent-free
plastic care and cleaning products .
Textile covers and trim parts on doors, boot
lid, etc. can be cleaned with special deter-
gents, e.g. dry foam. A soft sponge or brush
or a micro-fibre cloth for normal cleaning can
be used. Use special products to clean the
headliner. »

into pl

ace.
– Close the tank flap. Make sure you hear it
click

into place.
– Check that the fuel flap is properly closed. WARNING
Observe all relevant statutory regulations on
tran s

porting spare fuel canisters. For safety reasons, we do not recommend carrying a
sp
ar

e canister in the vehicle. The canister
could be damaged in an accident and fuel
may leak. Risk of fire! CAUTION
● Sw itc

h off the auxiliary heater (heater and
independent heater) before filling the tank.
● The fuel tank is full as soon as the automat-
ic fil
ler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber.
● Never completely empty the tank! An irreg-
ular f
uel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● If any fuel is spilt onto the paintwork of the
vehicl
e, it should be removed immediately.
Risk of damage to paintwork! 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. Note
The fuel tank capacity is around 55 litres, of
which 7 litr e

s are the reserve. Types of petrol
The correct grade of petrol is listed inside the
fuel
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).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
202

Checking and refilling levels
Super unleaded 98 octane or super 95 oc-
t ane u
n
leaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› . SEAT recommends “genuine Volkswagen
Gr
oup F
uel

Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t

ank flap.
We recommend the use of diesel fuel 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). »

Water in the fuel filter 1)
If
y
our vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. 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
