Keys, doors and windows21Extend the key and open the unit.
Replace the battery (battery type CR 2032), paying attention to the
installation position. Close the unit
and synchronise.
Radio remote control
synchronisation
After replacing the battery, unlock the
door with the key in the driver's door
lock. The radio remote control is
synchronised when the ignition is
switched on.
Fault
If the central locking system cannot
be operated with the radio remote
control, it may be due to the following:
● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the radio remote control while notin range, which will require re-
synchronisation.● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Electronic key system
Enables a keyless operation of the
following functions:
● central locking system 3 23
● starting the engine 3 137
The electronic key simply needs to be on the driver's person.
Additionally, the electronic key
includes the functionality of the radio
remote control 3 20.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Notice
Do not put the electronic key in the
load compartment or in front of the
Info-Display.
Replacing battery in electronic
key
Replace the battery as soon as the
system no longer operates properly
or the range is reduced. The need for battery replacement is indicated by a
message in the Driver Information
Centre 3 103.

Control indicator Y illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
During liquid gas operation, the
system automatically switches over to

If the fuel tank is empty, the engine
will not start.
The selected fuel mode is stored and reactivated at the next ignition cycle if
conditions allow.
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months, run the petrol tank
down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Fuel for liquid gas operation 3 168.
Faults and remedies
If gas mode is not possible, check the following:
● Is there enough liquid gas present?
● Is there enough petrol present for
starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the minimum requirements are not
fulfilled. If conditions allow, it may be possible to manually switch back to
liquid gas operation.
Seek the assistance of a workshop in
the event of all other faults.
