tem”Fig. 31
ISOFIX securing rings. You are obliged to follow the seat manufac-
t
ur
er's

instructions.
● Remove the protective caps of the “ISOFIX”
rings
by placing a finger in the hole and pull-
ing up ››› Fig. 31.
● Press the child seat onto the “ISOFIX” re-
taining rin
gs until the child seat can be heard
to engage securely. If the child seat is equip-
ped with Top Tether* anchor points, secure it
to the correspondent ring ››› Fig. 32. Observe
the manufacturer's instructions.
● Pull on both sides of the child seat to en-
sure th

Child seats with the “ISOFIX” and Top Tether*
attachment system are available from Techni-
cal Services. Attachment of the child seat with the

ether* retainer straps Fig. 32
Position of the Top Tether rings on the

of the rear seat. Child seats with the Top Tether system come
w
ith a s
tr

ap for securing the seat to the vehi-
cle anchor point, located at the back of the
rear seat backrest and provide greater re-
straint.
The objective of this strap is to reduce for-
ward movements of the child seat in a crash,
to reduce the risk of injuries to the head from
hitting the inside of the vehicle.
Using the Top Tether in rear-facing mounted
seats
Currently, there are very few rear-facing child
safety seats that have Top Tether. Please
carefully read and follow the seat manufac-
turer instructions to learn the proper way to
install the Top Tether strap. Securing the Top Tether* to the an-
chorag

e point Fig. 33

The essentials
Driver information system Intr oduction With the ignition switched on, it is possible
to r
e
ad the different functions of the display
by scrolling through the menus.
In vehicles with multifunction steering wheel,
the multifunction display can only be operat-
ed with the steering wheel buttons.
The number of menus displayed on the in-
strument panel will vary according to the ve-
hicle electronics and equipment.
A specialised workshop will be able to pro-
gramme or modify additional functions, ac-
cording to the vehicle equipment. SEAT rec-
ommends visiting a SEAT Official Service.
Some menu options can only be read when
the vehicle is at a standstill.
As long as a priority 1 warning is displayed, it
will not be possible to read the menus. Some
warning messages can be confirmed and
made to disappear with the windscreen wiper
lever button or the multifunction steering
wheel button.
The information system also provides the fol-
lowing information and displays (depending
on the vehicle's equipment):

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.

240 km/h (20 to 149 mph). The a

djustment
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

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 » 37

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 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. 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:
Press and hold the button ›››
 Fig. 120
4 for more than 5 seconds to consult the serv-
ic

sage.
When the service 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 .
The time can also be set via the  button

dealership, the display can be reset as fol-
lows: ●
Switc

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 Dealer. 38
