Replacing the key battery
Fig. 69 Master key:
Opening the cover
We recommend you have the batteries changed in a qualified
workshop. If you decide to change the used battery yourself, follow
the steps below:
– Carefully prise apart the key ⇒ fig. 69 A
and the cover B us-
ing a coin.
– Remove the cover in the direction of the arrow.
– Remove the used battery from the cover.
– Insert the new battery. Make sure that the “+” symbol on the
battery is facing downwards. The correct polarity is indicated on
the cover.
– After inserting the battery, align the cover and key and press
the two parts together.
For the sake of the environment
Used batteries must be disposed of at an appropriate waste facility or
through an authorised service, given that their components can affect the
environment.
Note
● The system must be re-synchronised after each battery replacement to
be able to lock and unlock the vehicle using the remote control
⇒ page 106.
● The new battery must be of the same type as the original.
Electronic immobiliser
The electronic immobiliser is designed to prevent unauthor-
ised persons from starting up the vehicle.
There is an electronic chip inside the key which automatically deactivates
the immobiliser when the key is inserted into the ignition lock. The electron-
ic immobiliser is enabled automatically when the ignition key is removed
from the ignition lock after coming to a stop.
If an uncoded key is used, the message SAFE will appear in the trip recorder
display.
Note
● The engine can only be started using an original SEAT key with the cor-
rect code.
● It may not be possible to start the engine with the key if there is another
ignition key from a different make of vehicle on the same key tab.
118Lights and visibility
Activating the function
–Briefly press the knob ⇒ fig. 87 to release it from its set posi-
tion.
– Turn the knob to position 1.
– Press the knob in again to prevent the setting from being
changed unintentionally.
Deactivating the function
– Briefly press the knob ⇒ fig. 87 to release it from its set posi-
tion.
– Turn the knob to position 0.
– Press the knob in again to prevent the setting from being
changed unintentionally.
The coming home and leaving home functions are controlled by light sen-
sors in the interior mirror housing. The system will function when the follow-
ing requirements are met:
● The knob is set to position 1.
● The headlights and the ignition are switched off.
● Dark conditions; the sensors register little or no light.
Coming home
When the system is enabled and it is dark, the corresponding exterior lights
switch on as soon as the driver door is opened.
The exterior lights will stay on for up to a maximum of 2 minutes as long as
one of the doors or the tailgate is open.
The exterior lights stay on for about 30 seconds to light up the area around
the vehicle after all the doors and the tailgate have been closed. This time interval is factory-set, but you can have it changed by a qualified
workshop to suit your own requirements (max. setting is 60 seconds).
Leaving home
The exterior lights are switched on when the vehicle is unlocked with the
button on the remote control key.
The exterior lights go out when the driver door is opened or after 60 sec-
onds when the vehicle locks itself again automatically
⇒ page 105.
WARNING
Before leaving the vehicle, remove the key from the ignition, as the lights
will not go out if the coming home function is activated. This will lead to
battery discharge and vehicle breakdown.
Note
● If you always wish to use the coming home and leaving home functions,
you can leave them permanently switched on. As the system is controlled
via a photosensor, it will only work in dark conditions.
● Permanent use of the coming home and leaving home functions, partic-
ularly on short journeys, will increase the load on the battery. To make sure
the battery is always sufficiently charged, occasionally drive longer distan-
ces.
● If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the ig-
nition.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here.
