If the warning lamps are ignored, the vehicle
may stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure that there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driver and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and allow it to cool.
● In any vehicle, the engine compartment is a
hazardous area and could cause severe inju-
ries ››› page 143. CAUTION
Failure to heed the warning lamps when they
appear may result in faults in the vehicle. SEAT information system
Introduction With the ignition switched on it is possible to
access different messages via the display on
the instrument panel display.
The number of messages displayed on the in-
strument panel display will vary according to
the vehicle 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 taking your car in for technical
service.
WARNING
Any distraction may lead to an accident, with
the risk of injury.
● Do not consult the messages on the instru-
ment panel screen when driving. Note
On the screen of the SEAT Portable System

Trip memo-
ry (for a
single jour-
ney).
The memory stores the values for the
journey and the consumption from
the moment the ignition is switched
on until it is switched off again.
If the journey is broken for more than
2 hours, the memory is automatically
erased. If the journey is continued in
less than 2 hours after the ignition is
switched off, the new data is added to
the data already stored in the memo-
ry.
2Total mem-
ory (for all
journeys).
The memory stores the values of any
number of journeys, until it counts a
total of 19 hours and 59 minutes of
driving, or 1999.9 km or miles of driv-
ing, depending on the type of instru-
ment panel fitted. On reaching either
of these limits, the memory is auto-
matically erased and starts to count
from 0 again. Possible displays

Remote control key Remote control key
With the vehicle key the vehicle may be
locked or unlocked remotely
››› page 45.
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 45 or the bat-
tery changed ››› page 44. Different keys belonging to the vehicle may
be used.
Folding the key shaft in and out
When the button is pressed
››› Fig. 27 A , the
key shaft is released and unfolds.
To fold it
press the button and fold the key
sh
aft in until it locks in place.
Replacing a key
To obtain a spare key and other vehicle keys,
the vehicle chassis number is required.
Each new key must contain a microchip and
be coded with the data from the vehicle elec-
tronic immobiliser. A vehicle key will not work
if it does not contain a microchip or the mi-
crochip has not been encoded. This is also
true for keys cut for the vehicle.
The vehicle keys or new spare keys can be
obtained from a SEAT dealership, a Special-
ised workshop or approved key service quali-
fied to create this kind of key.
New keys or spare keys must be synchron-
ised before use ››› page 45. WARNING
Careless or incorrect use of vehicle keys may
result in severe injury and accident.
● Always take all the keys with you whenever
you leave the vehicle. Children and unauthor-
ised individuals could lock the doors or the boot hatch, start the engine or turn on the ig-
nition, activating electrical systems, the elec-
tric windows, for example.
●
Never leave children or disabled people
alone in the car. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never remove the key from the ignition if
the vehicle is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. CAUTION
The remote control key contains electronic
components. Protect them from damage, im-
pacts and humidity. Note
● Only use the key button when you require
the corresponding function. Pushing the but-
ton unnecessarily could accidentally unlock
the vehicle or trigger the alarm. It is also pos-
sible even when you are outside the radius of
action.
● Remote control key operation can be great-
ly influenced by overlapping radio signals
around the vehicle working in the same range » 43Technical specifications

of frequencies (for example, radio
transmitters, mobile telephones).
● Obstacles between the remote control and
the vehicle, bad weather conditions and
draining batteries can considerably reduce
the range of the remote control.
● If the buttons of the vehicle key are press-
ed ››› Fig. 27 or one of the central locking but-
t on
s ››› page 45 is pressed repeatedly in
quick
succession, the central locking briefly
disconnects as protection against overload-
ing. The vehicle is then unlocked. Lock it if necessary. Vehicle mechanical key

Vehicle key: removing the battery44

Opening and closing
SEAT recommend having the batteries
changed in a specialised workshop.
The battery is located to the rear of the vehi-
cle key, under a cover.
Changing the battery
● Unfold the vehicle key shaft ››› page 43.
● Remove the cover from the back of the ve-
hicle key ››› Fig. 30 in the direction of the ar-
r o
w ››› .
● Extract the battery from the compartment
using a suitable thin object ››› Fig. 31 .
● Plac

e the new battery in the compartment,
pressing in the direction of the arrow as
shown ››› Fig. 31 ››› .
● Fit the battery compartment cover, pressing
in the direction of the arrow as shown
››› Fig. 30 until it clicks into place. CAUTION
● If the battery is not changed correctly, the
vehicle key may be damaged.
● Use of unsuitable batteries may damage
the vehicle key. For this reason, always re-
place the dead battery with another of the
same voltage, size and specifications.
● When fitting the battery, check that the po-
larity is correct. For the sake of the environment
Please dispose of your used batteries correct-
ly and with respect for the environment. Synchronising the vehicle key
If the button
 is pressed frequently outside
of the vehicle range, it is possible that the ve-
hicle can no longer be locked or unlocked us-
ing the key. In this case, the vehicle key must
be synchronised once more as follows:
● Unfold the vehicle key shaft ›››
page 43.
● Press the button  on the vehicle key. For
this, it must remain with the vehicle.
● Open the vehicle within one minute using
the key shaft.
● Turn on the ignition using the vehicle key.
The key has been synchronised.
● If necessary, fit the cap.
Central locking* and locking
system Introduction Central locking functions correctly when all
the doors and the rear lid are correctly shut.If the driver door is open, the vehicle
cannot
be locked with the key.
The battery of an unlocked vehicle parked for
a long period (e.g. in a private garage) may
run down and fail to start the motor. WARNING
The incorrect use of the central locking sys-
tem may cause serious injuries.
● The central locking system will lock all
doors. A vehicle locked from the inside can
prevent any non-authorised individual from
opening the doors and accessing the vehicle.
Nevertheless, in case of emergency or acci-
dent, locked doors will complicate access to
the vehicle interior to help the passengers.
● Never leave children or disabled people
alone in the vehicle. The central locking but-
ton can be used to lock all the doors from
within. Therefore, passengers will be locked
inside the vehicle. Individuals locked in the
vehicle can be exposed to very high or very
low temperatures.
● Depending on the time of the year, temper-
atures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never leave individuals locked in a closed
and locked vehicle. In case of emergency,
they may not be able to exit the vehicle by
themselves or get help. 45
