The seat belts are locked during
heavy acceleration or deceleration of
the vehicle, holding the occupants in
the sitting position. Therefore the risk
of injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 46.
Periodically check all parts of the belt
system for damage, pollution and
proper functionality.
Have damaged components replaced by a workshop. After an accident,
have the belts and triggered belt
pretensioners replaced by a
workshop.
Notice
Make sure that the belts are not
damaged by shoes or sharp-edged objects or are trapped. Prevent dirt
from getting into the belt retractors.
Seat belt reminder
Each seat is equipped with a seat belt reminder, indicated for driver's seat
by control indicator X in the
tachometer 3 85, for front
passenger seat by control indicator
k in the centre console 3 83, and
for rear seats by symbols X in the
Driver Information Centre 3 90.

80Instruments and controlsFuel gauge
Displays the level in the fuel tank.
The arrow indicates the vehicle side
where the fuel filler flap is located.
During liquid gas operation, the level
in the gas tank is displayed.
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 80.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Fuel selector
Pressing LPG 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.Press LPG. The LED in the button
shows the current operating mode.LED off:petrol operationLED

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.
Page 83 of 241

Instruments and controls81When 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 3 157.
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 might be possible to manually switch back to
liquid gas operation.
Seek the assistance of a workshop in
the event of all other faults.Caution
Repairs and adjustments may only
be 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 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.
