alarm system activation:

Seek the assistance of a workshop in
the event of faults.
Alarm
When triggered, the alarm gives off
an acoustic signal (horn) and a visual signal (hazard warning flashers). The
number and duration of which are
stipulated by legislation.
The alarm siren can be silenced by
pressing any button of the radio
remote control or by switching on the
ignition. The anti-theft alarm system is deactivated at the same time.
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Immobiliser
The system checks whether the
vehicle is allowed to start with the key being used. If the transponder in the
key is recognised, the engine can be
started.The immobiliser activates itself
automatically after the key has been removed from the ignition switch.
If control indicator A flashes when
the ignition is on, there is a fault in the
system; the engine cannot be started. Switch off the ignition and then repeat
the start attempt.
If control indicator A continues
flashing, attempt to start the engine
using the spare key and seek the
assistance of a workshop.
If control indicator A illuminates after
the engine has started, there is a fault in the engine electronics or
transmission electronics 3 81,
3 122, 3 127, or there is water in the
diesel fuel filter 3 90.
Notice
The immobiliser does not lock the doors. You should always lock the
vehicle after leaving it and switch on the anti-theft alarm system 3 21,
3 25.

90Instruments and controlsVehicle messagesMessages are given via the
instrument panel display or as
warning and signal buzzers. Check
control messages appear on the
Info-Display. Some appear in an
abbreviated form. Confirm warning
messages with the multifunction
control 3 86.
Warning chimes When starting the engine or
whilst driving ■ If seat belt is not fastened.
■ If a door or the tailgate is not fully closed when starting-off.
■ If a certain speed is exceeded with the parking brake applied.
■ If the speed programmed at the factory is exceeded.
■ If the vehicle has manual transmission automated and the
driver's door is opened when theengine is running, a gear is
engaged and the foot brake is not
depressed.
■ Warning signal sounds three times if the rear carrier system is
extended and reverse gear is
selected.
When the vehicle is parked and
the driver's door is opened ■ When the key is in the ignition switch.
■ With exterior lights on.
■ For manual transmission automated, if the parking brake is
not applied and no gear is engaged when the engine is switched off.
During an Autostop ■ If the driver's door is opened.
Battery voltage Low battery voltage in the radio
remote control. On vehicles without
check control, the message InSP3
appears in the instrument panel
display. Replace the battery 3 20.Brake light switch
Brake light does not come on during
braking. Have the cause of the fault
remedied immediately by a
workshop.
Drain diesel fuel filter
If there is water in the diesel fuel filter, the message InSP4 appears in the
instrument panel. In some models
InSP4 illuminates together with A in
the instrument. Consult a workshop.
Lighting
Important exterior lighting lamps,
including cables and fuses, are
monitored. In trailer mode, trailer
lighting is also monitored. Trailers
with LED lighting must have an
adapter that enables lamp monitoring as with conventional bulbs.

136Driving and operating
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
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 liquid gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If possible, close the manual shut-off
valve on the multivalve. The
multivalve is located on the liquid gas
tank in the load compartment,
underneath the rear floor cover.
Turn the thumb wheel clockwise.
If no further gas odour is perceptible
when the manual shut-off valve is
closed, the vehicle can be used in
petrol mode. If the gas odour persists, do not start the engine. Have the
cause of the fault remedied by a
workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights. Close the
manual shut-off valve on multivalve.
