The gear-change indicator is intended to help

mend the right gear for all driving situations.
In certain situations, only the driver can
choose the correct gear (for instance when
overtaking, driving up a steep gradient or
towing a trailer). Note
The display disappears from the instrument
panel when

you press the clutch pedal. Outside temperature display
When the outside temperature is below +4°C

The essentials
When the vehicle is at a standstill or when
tr av
el
ling at very low speeds, the tempera-
ture displayed may be higher than the true
outside temperature as a result of the heat
produced by the engine.
The temperatures measured range from
-40°C to +50°C (-40°F to +122°F).

that increase fuel consumption.
Follow them to reduce consumption. The indi-
cations appear automatically only with the ef-
ficiency programme. After a time, the tips will
disappear automatically.
If you wish to hide a saving tip immediately
after it appears, press any button on the
windscreen wiper lever*/multifunction steer-

● If y

ou hide a saving tip, it will reappear af-
ter you switch the ignition on again.
● The saving tips do not appear in all situa-
tions, but
rather with a large separation of
time. Speed warning device
The speed warning device warns the driver
when they h
av

e exceeded the pre-set speed
limit by 3 km/h (2 mph). An audible warning
signal sounds, and the warning lamp  and
the driver message Speed limit excee-
ded! will be displayed simultaneously on the
instrument panel. The warning lamp 
switches off when reducing speed below the
stored maximum limit.
Speed warning programming is recommen-
ded if you wish to be reminded of a maxi-
mum speed, such as when travelling in a
country with different speed limits or for a
maximum speed for winter tyres.
Setting speed limit warning
You can use the radio or the Easy Connect* to
set, alter or cancel the speed limit warning.

can be set from 30 to
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
speed limit. Service intervals

S EA
T di
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

ET
› ›
› Fig. 48 2 .
● Switch ignition back on. ●
Rel
e

ase the button 0.0/SET and press it

or the ne
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
