Operation
Anti-theft alarm When the vehicle is locked, the alarm is trig-
ger
ed when the el
ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 133.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 119. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

Advice
Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions (closing the win-
dows, roof and rear-view mirrors). If the vehi-
cle has special accessories such as spoilers
or a roof rack or two-way radio aerial, etc., 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 to the parking aid
sensors*, which are located in the rear bump-
er.
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: 258

Advice
Plastic parts Plastic parts are cleaned with a power wash-
er. If
thi
s is not sufficient, plastic parts
should only be treated with a special solvent-
free plastic cleaning agent . Do not use paint-
work cleaners, polishes or wax on plastic
parts.
Carbon parts The carbon parts on your vehicle have a pain-
t
ed s
ur

face. They do not need any special
care and are cleaned just like any other pain-
ted part ›››
page 257.
Paint damage Minor damage to the paint, such as scratches
or s
t
one c

hips, should be touched up without
delay before the metal starts to corrode. Suit-
able touch-up brushes or sprays for your car
can be obtained from a SEAT Official Service.
The number of the original paint finish on the
vehicle is given on the data sticker
››› page 289.
If corrosion is already visible it must be thor-
oughly removed by a specialised workshop. Windows Clear vision is an essential safety factor.
The wind
s

creen must not be cleaned with in-
sect remover or wax, otherwise the wind-
screen wipers will not function properly (jud-
dering).
Traces of rubber, oil, grease or silicone can
be removed with a window cleaning solution
or a silicone remover. Wax residue can only
be removed with a special cleaner. Your SEAT
Official Service will be able to provide you
with more detailed information.
The windows should also be cleaned on the
inside at regular intervals.
Use a separate cloth or chamois to dry the
windows. Cloths used for waxing and polish-
ing contain residues that will cause smears
on the glass. WARNING
Do not use water-repellent coatings on the
wind s

creen. In bad visibility conditions (e.g.
in the rain, dark or with a low sun), these
coatings may cause dazzle: risk of accident!
Such coatings can also cause the windscreen
wiper blades to make noise. CAUTION
● Remo v

e snow and ice from windows and ex-
terior mirrors with a plastic scraper only. To avoid scratches caused by dirt on the glass,
the sc
r

aper should only be pushed in one di-
rection and not moved to and fro.
● The heating element for the rear window is
located on the inner s
ide of the window. To
avoid damaging them, do not apply stickers
to these heating elements.
● Never use warm or hot water to remove
snow and ic
e from windows and mirrors. This
could cause the glass to crack! Rims
The wheels require regular attention to pre-
ser
v
e their ap

pearance. It is important to re-
move road salt and brake dust by washing
the wheels at regular intervals, otherwise the
finish will be impaired.
After washing, the wheels should only be
cleaned with an "acid-free" cleaning agent
for alloy wheels. This is available from SEAT
Official Services and specialist retailers. Nev-
er leave the cleaning agent on the rims for
any longer than specified in the instructions
before rinsing it off. If the wheel cleaner fluid
contains acid it can attack the surfaces of the
wheel bolts.
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.

Care and maintenance
WARNING
Please note when cleaning the wheels that
wat er
, ice and road salt can impair the effec-
tiveness of the brakes; this can cause an acci-
dent. Exhaust pipe
It is important to remove road salt and brake
dus
t

by washing the wheels at regular inter-
vals, otherwise the exhaust tail pipe material
could be damaged. To remove impurities, do
not use rim, paint or chrome cleaners or oth-
er abrasive products. Clean the exhaust tail
pipes with cleaning products that are suita-
ble for stainless steel.
SEAT Official Services carry stocks of cleaning
products that have been tested and ap-
proved for use on your vehicle.
Caring for the vehicle interior Scr een f

or the radio/Easy Connect*
and control panel* The display can be cleaned with a soft cloth
and a pr
of
e

ssionally available “LCD cleaner”.
Moisten the cloth with a small amount of the
cleaning fluid. The Easy Connect control panel* should first
be cle

aned with a brush so that no dirt goes
into the device or between the keys and
housing. Next, we recommend cleaning the
Easy Connect control panel* using a cloth
dampened with water and washing-up liquid. CAUTION
● To av oid s

cratching the screen, do not wipe
the display with a dry cloth.
● To avoid damage, ensure that no liquid
goes
into the Easy Connect control panel*. Plastic and leatherette parts
Plastic parts and leatherette can be cleaned
w
ith a d
amp c

loth. If this is not sufficient,
plastic parts and leatherette should only be
treated with a special solvent-free plastic
cleaner.
Textile covers and trim parts Textile covers and trim parts (e.g. seats, door
trim) shou
l
d be c

leaned regularly with a vac-
uum cleaner. This will remove surface dirt
which could otherwise be rubbed into the
textile material during use. Do not use steam
cleaners, as the steam could carry the dirt
deeper into the textile material. Normal cleaning
We rec

ommend that you use a soft sponge or
a commercially available lint-free, micro-fibre
cloth for normal cleaning. Only use brushes
on floor coverings and mats, as other textile
surfaces could become damaged.
In the case of normal surface dirt you can use
a foam cleaner. Use a sponge to spread the
foam on the textile surface and to work it into
the material lightly. However, make sure that
the textile material does not become soaking
wet. Then dab off the foam with a dry and ab-
sorbent cloth (e.g. a micro-fibre cloth) and
vacuum off any residue once the surface is
completely dry.
Cleaning stains
Treat drink stains (such as coffee or fruit
juice, etc.) with a cleaning solution for deli-
cate fabrics. This solution should be applied
with a sponge. If the stains are difficult to re-
move, a washing paste can be applied direct-
ly onto the stain and worked into the fabric.
The surface will then have to be wiped with
clear water to remove any residue left by the
paste. To do so, use a damp cloth or sponge
and then dab the stain with an absorbent
cloth.
Remove chocolate or make-up stains with a
cleaning paste (for e.g., soft soap). Then re-
move the soap with water (wet sponge). »

● 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 277, 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
over. Sulphuric acid could be spilt! Wheels
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.

in
g h
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 tyre pressure
››› page 283.
– 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
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap
››› Fig. 250.
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 maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap. Do not forget the spare wheel when checking
the tyre pr

essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
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. 251
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
Fig. 252
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. 252. 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. »

Advice
– If
y
ou wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of- ficial Service before purchasing them.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling ››› .
The s iz
e

s of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1)
). The vehicle documentation
varies depending on the country of resi-
dence.
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre:
205/55 R16 91V
This contains the following information:
205Tyre width in mm
55Height/width ratio in %
RTyre construction: Radial
16Rim diameter in inches
91Load rating code
VSpeed index The manufacturing date is also indicated on
the ty
r

e sidewall (possibly only on the outer
part):
DOT... 2216...
it means, for example, that the tyre was man-
ufactured in the 22nd week of 2016.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the
tyres rub against the bodywork, in certain
circumstances the tyres, running gear or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If
y

ou use tyres that are approved by SEAT
you can be sure that the actual tyre dimen- sions will be correct for your vehicle. If you
decide to fit

a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment. WARNING
● It i s

very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a
serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads. 1)
