2015 Seat Leon 5D engine

The essentials
you only need to change the oil when the ve-
hic l
e so r
equires. To calculate this change
(max. 2 years), the vehicle's conditions of
use and individual driving styles are consid-
ered. The pre-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
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. Service due
When the servic
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:

utton and
press it again for the next 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 ››› Book-
let 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 service. 39

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.
To protect the cooling system, the percentage
of additive must always be at least 40 %, 52
