Operation
●
Do not ap p
ly wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  r
e-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
An exhaust gas emission control system (cat-
alytic
c
on

verter) that functions perfectly is vi-
tally important for vehicle operation that re-
spects the environment.
Please observe the following indications:
● Refuel only using unleaded petrol in petrol
engine v
ehicles ››› page 202.
● Do not add too much oil to the engine
›››
page 209, Checking engine oil level .
● Do not switch off the ignition while driving.
If y
ou are required to drive in a country where
unleaded fuel is not available, when return-
ing to a country where using a catalytic con-
verter is obligatory, the catalytic converter
must be replaced. CAUTION
● Never c omp

letely empty the tank! An irreg-
ular fuel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● Refuelling just once with leaded petrol dis-
able
s the exhaust system! Particulate filter  (diesel
en
gines) The diesel engine particulate filter eliminates
mo
s
t

of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the fil- ter to burn. On completion of the cleaning
the warning l

amp will switch off.
If the lamp  does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Alw a

ys drive according to the road weather
conditions, the terrain and traffic.
● The particulate filter attains very high tem-
peratur
es. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire! CAUTION
While the warning lamp  is lit
up, the fuel
consumption is high, and in certain condi-
tions, the engine power is reduced. Note
● In order f or the p

articulate filter to burn off
soot in a correct manner, avoid carrying out
frequent short journeys.
● Using diesel fuel with a high sulphur count
can con
siderably reduce the useful life of the
particulate filter. The specialised service pro-
vides information about the countries where
fuel with a high sulphur content is used. 168

duce braking capability and prolong the brak-
ing distance – Risk of accident!
● Do not carry out any sudden or strong brak-
ing manoeu
vres after driving through water.
● Clean and dry the brakes as soon as possi-
ble af
ter driving through water by breaking
intermittently. Carry out braking in order to

if traffic so permits. Do not put other drivers
at risk. CAUTION
● In the event of

driving through water, parts
of the vehicle can be seriously damaged,
such as the engine, gearbox, catalytic con-
verter, suspension or the electrical system.
● Oncoming vehicles that drive through wa-
ter can c
ause waves that exceed your vehi-
cle's permitted level for driving through wa-
ter.
● There may be pot-holes mud or rocks under
the water th
at can hinder or prevent driving
through water.
● Do not drive through salt water. The salt
can cau
se rust. All components that are ex-
posed to salt water must be rinsed immedi-
ately with fresh water. Note
After driving through water we recommend
that

you contact a specialised service for an
inspection. Preventing damage to the vehicle
In order to prevent damage to the vehicle,
tak
e s

pecial care:
● on roads that are in poor condition,
● when mounting kerbs,
● when approaching very steep ramps, etc.,
● with the parts of the vehicle situated on the
low er p

art of the vehicle, i.e. the spoiler, the
exhaust pipe.
This applies especially to vehicles with a very
low suspension (sport) and when the vehicle
is fully loaded. Driver assistance systems

General information Assorted assistance systems – which vary
depending on the equipment
fitt

ed in the car
– will help you when parking or manoeu-
vring.
The rear parking aid is an audible assistant
that warns about obstacles located behind
the vehicle ›››
page 171.
During parking, Parking System Plus assists
the driver by visually and audibly warning
them about obstacles detected in front and
behind the vehicle ›››
page 172. WARNING
● Alw a

ys pay attention, also when looking
straight ahead, to traffic and the vehicle sur-
roundings. The assistance systems are not a
replacement for driver awareness. When in-
serting or removing the vehicle from a park-
ing space, or when performing similar ma-
noeuvres the driver always assumes the re-
sponsibility.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions.

4 The cruise control system allows you to drive
at
a c
on

stant speed of 30 km/h (19 mph) or
higher without having to press the accelera-
tor. However, the speed is only maintained
within the margin permitted by the engine
power and the braking effect of the engine.
The  warning lamp lights up on the general
instrument panel if cruise control is switched
on. WARNING
● For s af

ety reasons the cruise control sys-
tem must not be used in dense traffic or
where roads conditions are poor (e.g. due to
ice, aquaplaning, loose grit, snow). – Risk of
accident!
● The programmed speed can only be re-es-
tabli
shed if it is not too high for current traf-
fic conditions.
● Always switch the cruise control system off
after u
sing it in order to avoid involuntary
use. CAUTION
● The crui se c

ontrol cannot maintain a con-
stant speed when the vehicle is moving
downhill. The vehicle tends to accelerate un-
der its own weight. Therefore, shift down or
use the brake pedal in good time to slow the
vehicle. Note
● In v ehic

les with an automatic gearbox, the
cruise control system cannot be switched on
if the selector lever is in position P, N or R.
● In vehicles with a manual gearbox, the

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

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.

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

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. »
