Trip computer 1 and 2 The information of two trip computerscan be reset separately for odometer,
average consumption and average
speed by pressing the SET/CLR
button, making it possible to display
different trip information for different
drivers.Trip odometer
Trip odometer displays the recorded
distance since a certain reset.
Trip odometer counts up to a distance
of 2,000 miles then restarts at 0.
To reset, press the SET/CLR button
for a few seconds.
Range
Range is calculated from current fuel
tank content and current
consumption. The display shows
average values.
After refuelling, the range is updated
automatically after a brief delay.
When the fuel level in the tank is low, a message appears on vehicles with
Uplevel-Combi-Display.
When the tank needs to be refuelled
immediately, a warning code or
warning message is displayed on
vehicles with Midlevel-Display or
Uplevel-Combi-Display.
Additionally the control indicator i in
the fuel gauge illuminates or flashes
3 115.
Average consumption
Display of average consumption. The measurement can be reset at any
time and starts with a default value.
To reset, press the SET/CLR button
for a few seconds.
Instantaneous consumption
Display of the instantaneous
consumption.
Average speed
Display of average speed. The
measurement can be reset at any
time.
Driving and operating209
Pressing Y switches between petrol
and natural gas operation. Switching
is not possible at high loads (e.g.
strong acceleration, running at full
throttle). The LED status shows the
current operating mode.1 off=natural gas
operation1 illumi‐
nates=petrol operation1 flashes=no switching is
possible, one type of
fuel is empty
As soon as the natural gas tank is empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is started-up again. This
will prevent damage to the catalytic
converter (overheating caused by
irregular fuel supply).
If the selector switch is operated
several times within a short time, a
switchover block is activated. The
engine remains in the current
operating mode. The block remains
active until the ignition is switched off.
A slight loss of power and torque can be expected during petrol operation.
You must therefore adapt your driving
style (e.g. during overtaking
manoeuvres) and vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
210Driving and operating9Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
Petrol and Diesel refuelling
To open, turn the cap slowly anti-
clockwise.The fuel filler cap can be retained in
the bracket on the fuel filler flap.
For refuelling, fully insert the pump
nozzle and switch it on.
After automatic cut-off, it can be
topped up with max. two doses of fuel.
Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and let engage.
Driving and operating211
Vehicles with misfuel inhibitor9Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
The misfuel inhibitor ensures that the flap of the fuel filler neck can only be
opened by using a nozzle for diesel
fuel or a funnel for emergency
refilling.
Turn the fuel filler cap slowly anti-
clockwise.
The cap can be retained in the
bracket on the fuel filler flap.
Place the nozzle in straight position to
the filler neck and press with slight
force to insert.
In case of an emergency refilling with a canister, a funnel must be used to
open the cap of the filler neck.The funnel is located on the right side storage in the load compartment.
Place the funnel in straight position to
the filler neck and press with slight
force to insert.
Use the funnel to fill in the diesel fuel
into the filler neck.
After topping-up, put the funnel into
the plastic bag and stow it in the
storage compartment.

Natural gas refuelling
212Driving and operating
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.9 Warning
Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed, i.e. the filler neck must be
vented.
The capacity of the natural gas tank depends on outside temperature,
filling pressure and type of refuelling
system. Capacities 3 284.
Close the flap and allow it to engage. Terms for "natural gas vehicles"

Liquid gas refuelling
Follow the operating and safety
instructions of the filling station when
refuelling.
The filling valve for the liquid gas is
behind the fuel filler cap.
Unscrew protective cap from the filler neck.
Screw the required adapter hand-
tight onto the filler neck.
