a
dar sensor is covered temporarily
with some kind of accessory, such as an ad-
ditional headlight or the like.
● When the vehicle is to be loaded on a lorry,
ferry
or train.
System limitations The Front Assist has certain physical limita-
tions
inher

ent to the system. Thus, in certain
circumstances, some of the system's reac-
tions may be inopportune from the driver's
standpoint. So pay attention in order to inter-
vene if necessary.
The following conditions may cause the Front
Assist not to react or to do so too late:
● In the first few instants of driving after
swit c

hing on the ignition, due to the system’s
initial auto-calibration.
● On taking tight bends or complex paths.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged.
● If the ASR h

as been disconnected or the
ESC activ
ated in Sport mode manually
››› page 158.
● If the ESC is controlling.
● If several brake lights of the vehicle or elec-
trical ly

connected trailer are damaged. ●
If the r a

dar sensor is dirty or covered.
● If there are metal objects, e.g. rails on the
roa
d or sheets used in road works.
● If the vehicle is reversing.
● If the vehicle over-accelerates.
● In case of snow or heavy rain.
● In case of narrow vehicles, such as motor-
bike

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.

Operation
descending a slope in order to take advant-
ag e of
the en
gine brake.
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

Care and maintenance
●
The modification of the s
uspension of the
vehicle wheels, including the use of non-per-
mitted combinations of tyres and rims can al-
ter the operation of the airbag system and in-
crease the risk of serious or fatal injuries in
an accident.
● During all jobs on the airbag system, in ad-
dition to the remo
val and fitting of parts of
the system in the course of other repair jobs,
parts of the airbag system can be damaged.
Therefore in the event of an accident, this
may cause the airbags to activate incorrectly
or not activate at all. Radio and aerial reception
In vehicles factory-fitted with an audio or
n
av
ig

ation system, the aerial may be instal-
led in different places:
● inside the rear window next to the heating
elements,
● on the roof

of the vehicle.
Care and cleaning Introduction Regular and suitable care helps to
m
aint ain
the u
seful life of your vehicle. This may also
be one of the requirements for upholding any warranty claims in the event of corrosion or
paint def

ects.
We recommend you use cleaning products
from the SEAT Original Accessories pro-
gramme available in SEAT dealers. Please fol-
low the instructions for use on the packag-
ing. WARNING
● Cle

aning products and other materials used
for car care can damage the health if mis-
used.
● Always keep car care materials in a safe
plac
e out of the reach of children. Risk of poi-
soning!
● When washing the car during the winter
season: Moi
sture and ice on the brakes may
affect braking efficiency. Risk of accident!
● The ignition must always be switched off
when the car is
washed. Risk of accident!
● Do not clean the underside of the car or in-
side the wheel ar
ches without protecting your
hands and arms. You may cut yourself on
sharp metal parts!
● Perfumes and air fresheners inside the ve-
hicle m
ay be harmful to health at high tem-
peratures in the interior. CAUTION
● Check the c

olour-fastness of your clothing
to avoid damaging or visibly staining the fab-
ric (leather), upholstery and fabric trim. ●

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. »

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
performance problems. Engine compartment

Checking and refilling levels
– Re
a
d off the coolant level on coolant ex-
pansion tank ››› Fig. 207. When the engine
is cold, the coolant should be between marks B (min.) and
A (max.). When the
en gine i
s

hot, it may be slightly above mark
A (max.).
If the c
oo

lant fluid level in the reservoir is too
low, this will be indicated by the  red warn-
ing lamp illuminating on the general dash
panel ››› page 210, Control lamp . However,
we recommend checking the coolant level di-
rectly in the tank.
Coolant fluid loss
Any loss of coolant normally indicates a leak.
It is not sufficient merely to top up the cool-
ant. The cooling system should be inspected
by an Official Service without delay. CAUTION
● In the event of

a fault that causes the en-
gine to overheat, contact an authorised SEAT
dealer immediately, as this could damage the
engine.
● Anti-freeze that does not correspond to the
correct
specification may particularly affect
corrosion protection considerably.
● Faults caused by corrosion may lead to
cool
ant leaks. Risk of serious engine faults! Topping up the coolant level
–
Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion
tank ›

›› Fig. 207 with a cloth and carefully
unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into
plac

e.
Do not use a different type of additive if the
prescribed anti-freeze additive is not availa-
ble, in the event of an emergency. In this
case, use only water and bring the coolant
concentration back up to the correct level as
soon as possible at an Official Service.
Always top up with unused coolant.
Never fill the coolant tank above mark A (max.)

Fig. 207 Excess coolant is forced
out of the cooling system through the over-
pressure valve in the filler cap of the expan-
sion tank when the engine heats up. WARNING
● The anti-freez e a

dditive and, therefore, the
entire coolant, are a health hazard. Avoid
touching the coolant. Coolant fumes are also
a health hazard. For this reason, always store
the coolant additive in a safe place out of the
reach of children. Risk of poisoning! ●
If s p

lashed into eyes, rinse immediately
with clean water and seek immediate medical
attention.
● Seek immediate medical attention if the
cool
ant is accidentally ingested. CAUTION
If the coolant cannot be topped up under the
