Changing the battery of the radio remote control
Each remote control key contains a battery which is housed in the cover
of the transmitter housing ⇒ page 43, fig. 38. We recommend having
the battery of the key replaced by a specialist garage. You should,
however, proceed as follows if you wish to replace the battery yourself:
– Fold open the key.
– Use a thin screwdriver to carefully lever off the front part of the key
⇒ page 43, fig. 38 from the transmitter housing .
– Take off the cover of the transmitter housing ⇒ fig. 39 in direction of
arrow.
– Take the used battery out of the housing cover.
– Insert the new battery. Ensure that the “+” symbol on the battery is
facing downwards. The correct polarity is also shown on the cover of
the transmitter housing.
– Insert cover with battery in place at the rear of the transmitter housing
and press both parts together.
– Insert the transmitter housing into the front part of the key so that the
two parts lock into each other.
For the sake of the environment
Dispose of an old battery in accordance with environmental regulations.
Note
• The replacement battery must have the same specification as the original
battery.
• If it is still not be possible to unlock or lock the vehicle with the remote control
even after replacing the battery this means that the system has to be synchronised
⇒ page 50.
Electronic immobiliser
The electronic immobiliser prevents the vehicle being operated by an
unauthorised person.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock. The elec-
tronic immobiliser is automatically activated when you withdraw the ignition key
from the lock.
