Operation
In vehicles with Services est ablished by
time or mil eage, 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 variation
(max. 2 years), the vehicle's conditions of use
and individual driving styles are considered.
The advance warning first appears 20 days
before the date established for the corre-
sponding service. The kilometres (miles) re-
maining until the next service are always
rounded up to the nearest 100 km (miles) and
the time is given in complete days. The cur-
rent service message cannot be viewed until
500 km after the last service. Prior to this, on-
ly lines are visible on the display.
Inspection reminder
If a service or an inspection has to be carried
out soon, a service reminder will be dis-
played when the ignition is switched on.
The figure displayed are the kilometres that
can still be travelled or the time until the next
service. Service due
When the time for a service
or an inspec-
tion comes, an audible warning will be emit-
ted when the ignition is switched on and the
fixed key symbol > may appear on the in-
strument panel for a few seconds, along with
one of the following messages:
