240 km/h (20 to 149 mph). The adjustment
is made at 10 km/h (5 mph) intervals. Note
● Ple a

se bear in mind that, even with the
speed warning function, it is still important
to keep an eye on the vehicle speed with the
speedometer and to observe the legal speed
limits.
● The speed limit warning function in the ver-
sion for some c
ountries warns you at a speed
of 120 km/h (75 mph). This is a factory-set

stinguishes between services with en-
gine oil change (e.g. Oil change service) and
services without engine oil change (e.g. In-
spection).
In vehicles with Services established by time
or mileage, the service intervals are already
pre-defined.
In vehicles with LongLife Service , the inter-
vals are determined individually. Thanks to
technological progress, maintenance work
has been greatly reduced. Because of the
technology used by SEAT, with this service
you only need to change the oil when the ve- hicle so requires. To calculate this change
(max. 2 y

ears), the vehicle's conditions of
use and individual driving styles are consid-
ered. The advance warning first appears 20
days before the date established for the cor-
responding service. The kilometres (miles)
remaining until the next service are always
rounded up to the nearest 100 km (miles)
and the time is given in complete days. The
current service message cannot be viewed
until 500 km after the last service. Prior to
this, only lines are visible on the display.
Inspection reminder
When the Service date is approaching, when
the ignition is switched on a Service remind-
er is displayed.
Vehicles without text messages : a span-
ner  will be displayed on the instrument
panel plus an indication in km.
The kilometres indicated are the maximum
number of kilometres that can be travelled
until the next service. After a few seconds,
the display mode changes. A clock symbol
appears and the number of days until the
next service is due.
Vehicles with text messages : Service in
--- km or --- days will be shown on the
instrument panel display. 44

The essentials
Service due
When the ser v
ic
e date is due, an audible
warning is given when the ignition is switch-
ed on and the spanner displayed on the
screen flashes for a few seconds .
Vehicles with text messages : Service now
will be shown on the instrument panel dis-
play.
Reading a service notification
With the ignition switched on, the engine off
and the vehicle at a standstill, the current
service notification can be read:
Press and hold the button 0.0/SET for more
th an 5 sec
ond

s to consult the service mes-
sage ››› Fig. 48 2 .
When the ser v
ic

e date has passed , a minus
sign is displayed in front of the number of kil-
ometres or days.
Vehicles with text messages : the following
message is displayed: Service --- km
(miles) or --- days ago .
Resetting service interval display
If the service was not carried out by a SEAT
dealership, the display can be reset as fol-
lows: ● Switch off the ignition, press and hold the
button 0.0/S

xt 20 seconds. Note
● The serv ic

e message disappears after a few
seconds, when the engine is started or when OK/RESET is pressed on the windscreen wiper
lev er

, or OK on the multifunction steering
wheel.
● In v
ehicles with the LongLife system in
which the batt
ery has been disconnected for
a long period of time, it is not possible to cal-
culate the date of the next service. Therefore
the service interval display may not be cor- rect. In this case, bear in mind the maximum
service intervals permitted in the ››› Booklet
Maintenance Programme.
● If you reset the display manually, the next
servic
e interval will be indicated as in vehi-
cles with fixed service intervals. For this rea-
son we recommend that the service interval
display be reset by a SEAT authorised Dealer. Cruise control

Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25°C
(-13°F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant. 60

o

lutions per minute ››› Fig. 122 1 .
Tog ether w
ith the gear-change indicator, the
rev counter offers you the possibility of using
the engine of your vehicle at a suitable
speed.
The start of the red zone on the dial indicates
the maximum engine speed which may be
used briefly when the engine is warm and af-
ter it has been run in properly. Before reach-
ing this range, you should change to a higher
gear for vehicles with a manual gearbox or for
automatic gearboxes put the selector lever in
“D” or take your foot off the accelerator ped-
al.
We recommend that you avoid high revs and
that you follow the recommendations on the
gear-change indicator. Consult the additional
information in ›››
 page 42, Gear-change
indicator. CAUTION
Never allow the rev counter needle

 page 72. Note
● The w inds

creen and window wipers only
function when the ignition is switched on and
the bonnet or rear lid, respectively, are
closed.
● The interval wipe speed varies according to
the vehic

ly thaws the frozen jets, it
does not thaw the water in the washer hoses.
When the ignition is switched on the heated
windscreen washer jets automatically adjust
the heat depending on the ambient tempera-
ture.
Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed.
Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray. Note
The wiper will try to wipe away any obstacles
that ar

e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. 149

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.

Advice
Engine oil Gener a
l
notesThe engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 60, Engine oil
specifications.
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6, this means that your vehicle has the LongLife
serv
ic

e programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terv
als.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 273 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 60 (up to a maximum of 0.5
litres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals, which also appear in
›››  page 60, Engine oil specifications
. In
this case, your vehicle must be serviced after
a fixed interval of 1 year/15,000 km (10,000 miles)(whatever comes first)
›››
Booklet
Maintenance Programme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 273 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 273,
Checking engine oil level and you cannot ob-
tain the oil specified for your vehicle, you can
use a small quantity of oil (once) conforming
to the VW 506 00, VW 506 01, VW 505 00,
VW 505 01 or ACEA B3/ACEA B4 specification
(up to 0.5 l).

necessary. Depending on how you drive and the condi-
tions in whic

h the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney. WARNING
Any work carried out in the engine compart-
ment or on the en gine mu

st be carried out
cautiously.
● When working in the engine compartment,
