90Instruments and controlsFuel gauge
Displays the level in the fuel or gas
tank depending on the operation mode.
The arrow indicates the vehicle side
where the fuel filler flap is located.
Control indicator i 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 90.
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.

If engine coolant temperature is
too high, stop vehicle, switch off

coolant level.
Service display
The engine oil life system lets you
know when to change the engine oil
and filter. Based on driving
conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.
In the Uplevel-Display or
Uplevel-Combi-Display the remaining
oil life duration is displayed in the
Vehicle Information Menu .
In the Midlevel-Display the remaining
engine oil life duration is displayed by
the control indicator I. The ignition
must be switched on, with the engine
not running.
The menu and function can be
selected via the buttons on the turn
signal lever.
To display the remaining engine oil
life duration:Press MENU to select the Vehicle
Information Menu .
Turn the adjuster wheel to select Remaining Oil Life .
The system must be reset every time
the engine oil is changed to allow proper functionality. Seek the
assistance of a workshop.
Press SET/CLR to reset. The ignition
must be switched on, with the engine not running.
When the system has calculated that
engine oil life has been diminished,
Change Engine Oil Soon or a warning
code appears in the Driver
Information Centre. Have engine oil

Driving and operating143Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
● The stop-start system is not manually deactivated.
● The bonnet is fully closed.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The defrost selection does not inhibit an Autostop.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.● The self-cleaning function of the diesel particle filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
An Autostop may become less
available as the ambient temperature
approaches the freezing point.
Certain settings of the climate control
system may inhibit an Autostop. See
" Climate control " chapter for further
information 3 132.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 140.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating aredisabled or switched into a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 96.
Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically by the stop-start system.

Driving and operating161Full 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 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
around 60 seconds (depending on
exterior temperature) and the first firm
press on the accelerator. The LED
1 status shows the current operating
mode.1 off:petrol operation1 flashes:checking conditions

five times
and extin‐
guishes:liquid gas tank is

message is displayed
in the Driver
Information Centre.
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 i
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 liquid gas mode.

176Vehicle carethe coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
Power steering fluid level normally
must not be checked. If an unusual
noise sounds during steering or the
power steering reacts conspicuous
seek the assistance of a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Brakes
In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.

222Service and maintenanceAdditional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade
depending on the minimum ambient
temperature 3 225.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. Innorthern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional coolant additives will be rejected.
Brake and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified
interval.
