Instruments and controls81Fuel 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 81.
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.LED off:petrol operationLED

guishes:liquid gas tank is empty
or failure in liquid gas
system. A message is
displayed in the Driver
Information Centre.
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.
82Instruments and controlsWhen petrol fuel tank is empty, the
engine will not start.
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
whether there is enough liquid gas or 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 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 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.

Instruments and controls83Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
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.
When the system has calculated that
engine oil life has been diminished, a warning message appears in theDriver Information Centre. Have
engine oil and filter changed by a
workshop within one week or
300 miles, whichever occurs first.
This can be an additional engine oil
and filter change or part of a regular
service.
Midlevel Display
The remaining engine oil life duration
is displayed in percent beside the
control indicator I on the Midlevel
Display.
Uplevel Display
The remaining oil life duration is
displayed in percent in the Vehicle
Information Menu on the Uplevel
Display.
To display the remaining engine oil
life duration use the buttons on the
stalk:
Press MENU to select the Vehicle
Information Menu .
Turn the adjuster wheel to select Remaining Oil Life .
Reset Press SET/CLR on the stalk for
several seconds to reset. The
remaining engine oil life duration
page must be active. Switch on
ignition only, engine must be
switched off.
The system must be reset every time
the engine oil is changed to ensure
proper functionality. Seek the
assistance of a workshop.
132Driving and operatingDuring an Autostop, the heating and
brake performance will be
maintained.
Conditions 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 climate control system allows an Autostop.
● The brake vacuum is sufficient.● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for more
details 3 121.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 129.
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, e.g. the rear window
heating, are disabled 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 driverVehicles with manual transmission:
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 88.Vehicles with manual transmission
automated:
Release the brake pedal or move
selector lever out of D to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
Vehicle care169Capacities 3 226.
Fit the cap on straight and tighten it.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 214.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Service and maintenance215Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil based on its quality and on the
minimum ambient temperature
3 218.
Additional 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 3 218.All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern 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.Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
