airbags or belt pretensioners are
deployed, the vehicle is
automatically unlocked.
Notice
A short time after unlocking with the
remote control the doors are locked
automatically if no door has been
opened.Unlocking
Press button c.
Two settings are selectable: ■ To unlock only the driver's door, load compartment and fuel filler
flap, press button c once. To unlock

78Instruments and controlsFuel gauge
Displays the fuel level or gas level in
the tank depending on the operation
mode.
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
petrol operation when gas tanks are
empty 3 78.
Never run the tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.

petrol and liquid gas operation. The

■ Digital speed
■ Range
■ Instantaneous consumption
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 and then restarts at 0.
To reset, press the SET/CLR button
for a few seconds.
Fuel 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-Display.
When the tank must be refuelled
immediately, a warning code or
warning message is displayed on
vehicles with Midlevel- and Uplevel-
Display.
Additionally the control indicator Y in
the fuel gauge illuminates or flashes

Fuel range LPG version
Display of approximate fuel range
available with the remaining fuel in
each respective fuel tank of gasoline
and LPG fuel, along with a total range
of both fuel types together. Switch
between the mode by pressing
SET/CLR button.
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.

Driving and operating145
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after approx. 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.LED off=petrol operationLED illu‐
minates=liquid gas operationLED
flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
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.
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.
Seek the assistance of a workshop in the event of all other faults.

Storage for a long period of time
If the vehicle is to be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir.
