Fault
If the central locking system cannot be
operated with the remote control, it may be
due to the following:
z The range of the remote control has
been exceeded.
z Remote control battery voltage is too
low. Battery replacement - see next
page.
z Frequent, repeated operation of the
remote control outside the reception
range of the vehicle (e.g. too far from
vehicle, remote control is then no longer
recognised). Remote control
synchronisation – see next page.
z If the central locking system is
overloaded as a result of repeated
operation at short intervals. The power
supply is cut off for a brief period.
z Interference from higher-power radio
waves from other sources.
To eliminate the cause of a fault, we
recommend contacting a workshop for
assistance.
Manual unlocking and locking using the
vehicle key, see page 33.
Remote control battery replacement
Replace the battery as soon as the range
of the remote control begins to shrink.
Extending the key – see page 26.
Open the remote control. Replace the
battery (battery type – see page 293),
noting installation position. Close the
remote control.
Make sure that you dispose of old batteries
in accordance with environmental
protection regulations.
Remote control synchronisation
After a battery change, unlock door with
key in lock, see page 33. Inserting the key
into the lock synchronises the remote
control.
