The towline anchorages are located under
the floor panel in the luggage compartment.Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times.
Tow rope or tow bar
The tow bar offers increased safety and a
lower risk of damage.
The tow rope is recommended when there is
no tow bar. It must be elastic so that it does
not damage the vehicle.
Towline anchorages
Attach the bar or rope to the towline ancho-
rages.

Operation
Service interval display Service interval display The service interval indication appears on the
instrument panel display
››› Fig. 82 4 .
SEAT distinguishes between services with en-
gine oi l
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
pr e-defined.
In

vehicles with LongLife Service , the inter-
vals are determined individually. Technical
progress has made it possible to considera-
bly reduce servicing requirements. The tech-
nology used by SEAT ensures that your vehi-
cle only has an Oil Servicing when it is neces-
sary. To establish when the oil servicing is
due (max. 2 years), the vehicle's conditions
of use and individual driving styles are con-
sidered. The service pre-warning first ap-
pears 20 days before the date established for
the corresponding 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. Pri-
or 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.
In vehicles without text messages , a s
panner
is displayed on the instrument panel  with
a figure giv
en in km. The number of kilome-
tres shown is the maximum number that may
be driven 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 appointment is due.
In vehicles with text messages , Serv
ice in ---
km (miles) or --- days is displayed on the in- strument panel.
Service due
After the service date, an audible warning is
given when the ignition i
s switched on and
the spanner displayed on the screen flashes
for a few seconds . In
vehicles with text
messages, Service in --- km or --- days is dis-
played on the instrument panel.
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. 82 4 for
more than 5 seconds to consult the service
message. When the service date has past
, a minus sign
is displayed in front of the number of kilome-
tres or days. In vehicles with text messages
the following is displayed: Service --- km
(miles) or --- days ago .
The time can also be set via the  key and
Setup function button in the Easy Connect
system ››› page 81 .
R e

setting service interval display
If the service was not carried out by a SEAT
dealership, the display can be reset as fol-
lows:
● To reset the service interval display, turn
the ignition off and press and hold the but-
ton ››› Fig. 82 4 .
● Switch the ignition back on.
● Release the button ››› Fig. 82 4 and press
the button 4 again for the next 20 seconds.
Note
● The service message disappears after a few
seconds, when the engine is started or when OK/RESET is pressed on the windscreen wiper
lever, or OK on the multifunction steering
wheel.
● In vehicles with the LongLife system in
which the battery 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 80

Opening and closing
Note
● Never leave any valuable items in the vehi-
cle unattended. Even a locked vehicle is not a
safe.
● If the diode on the driver door sill lights up
for about 30 seconds when the vehicle is
locked, the central locking system or anti-
theft alarm* is not working properly. You
should have the fault repaired at a SEAT Offi-
cial Service or specialised workshop.
● The vehicle interior monitoring of the anti-
theft alarm* system will only function as in-
tended if the windows and the sunroof* are
closed. Car key

The vehicle key includes an emitter and bat-
tery. The receiver is in the interior of the vehi-
cle. The range of the vehicle key with remote
control and new battery is several metres
around the vehicle.
If it is not possible to open or close the vehi-
cle using the remote control key, this should
be re-synchronised ››› page 87 or the bat-
tery changed ››› page 86 .
Diff er
ent keys belonging to the vehicle may
be used.
Control lamp on the vehicle key
When a button on the vehicle key is pressed,
the control lamp flashes ››› Fig. 91 (arrow)
once briefly

, but if the button is held down for a longer period the control lamp flashes sev-
eral times, such as in convenience opening.
If the vehicle key control lamp does not light
up when the button is pressed, replace the
key's battery

Unfo

lding and folding the key shaft
Press button 1
››› Fig. 91 or
›
›› Fig. 92
to un-
lock and unfold the key shaft.
To fold the shaft away, press button 1 and
fold the key shaft in until it locks in place.
Alarm button*
Only press alarm button 2 in the event of an
emergency! When the alarm button is press-
ed, the vehicle horn is heard and the turn sig-
nals are switched on for a short time. When
the alarm button is pressed again, the alarm
is switched off.
Replacing a key
To obtain a spare key and other vehicle keys,
the vehicle chassis number is required.
Each new key contains a microchip which
must be coded with the data from the vehicle
electronic immobiliser. A vehicle key will not
work if it does not contain a microchip or the
microchip has not been encoded. This is also
true for keys which are specially cut for the
vehicle. »
