106Instruments and controlsThe LED status shows the current
operating mode.LED off:petrol operationLED illu‐
minates:natural gas operationLED
flashes for
approx.
five
seconds:fuel mode transition is
selected but switching
is not possibleLED
flashes:fuel mode transition in
process, flashing stops
if transition is completed
Switching is not possible at high loads
(e.g. powerful acceleration, driving at
full throttle).
If the selector switch is operated
several times within a short time, a
switchover inhibitor is activated. The
engine remains in the current
operating mode. The inhibitor
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 high vehicle loads
(e.g. towing loads) accordingly.
The vehicle consumes petrol when
starting the engine and even when in certain natural gas operating modes.The petrol consumption in natural gas
operating mode can vary depending
on driving behaviour (e.g. high load or towing). In case of a low fuel level, a
corresponding message is displayed as a reminder to refuel.
Note
Always ensure that there is enough
petrol in the tank.
Fuel for natural gas operation 3 221.
Forced fuel mode transitionNatural gas tank is running low
As soon as the natural gas tank is
empty, petrol operation is
automatically engaged. Manually
engaging natural gas operation mode is not possible until natural gas
refuelling is detected.
Before the petrol fuel system runs empty, a warning message will be
displayed and cannot be dismissed.Petrol tank is running low while
natural gas is available
If the remaining petrol level in the tank falls below a certain level, natural gas
operation is automatically engaged
provided there is a sufficient natural
gas level in the tank. Manually
engaging petrol operation mode is not
possible.
Before both fuel systems run empty,
a warning message will be displayed
and cannot be dismissed.
Engine coolant temperaturegauge
Displays the coolant temperature.

coolant level.
Service display
The engine oil life system informs
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,
Change Engine Oil Soon appears in
the Driver Information Centre. Have engine oil and filter changed by a
workshop within one week or
500 km, whichever occurs first.
This can be an additional engine oil
and filter change or part of a regular
service.
The remaining oil life duration menu
is displayed in the Driver Information
Centre 3 115.
On Midlevel display select the
Settings Menu by pressing MENU on
the turn signal lever. Turn the adjuster wheel to select the Remaining Oil
Life page.

Driving and operating163An Autostop can be activated at a
speed lower than 5 km/h.
Activate a conventional Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.
Early Autostop
Only the engine B16DTU has early
Autostop in addition to conventional
Autostop.
An Autostop can be activated at a
speed lower than 14 km/h.
Early Autostop is inhibited if the
incline is greater than 5%.
Activate an early Autostop as follows: ● Depress the brake pedal sufficiently.
● Depress the clutch pedal.
The engine will be switched off while the ignition stays on.
Early Autostop is inhibited when the
turn signal is on, trailer hitch is
connected, the steering wheel is
moved beyond a certain point or the
inclines is greater than 5%.Vehicles with automatic transmission
or manual transmission automated
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
After restart, the idle speed is
indicated.
During an Autostop the performance
of the vehicle 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 brake vacuum is sufficient.
● Between the last Restart and a new Autostop must be about
10 s.

Vehicle care233When the engine oil level has
dropped to the MIN mark, top up
engine oil.
The engine oil level must not exceed
the MAX mark on the dipstick.
We recommend the use of the same
grade of engine oil that was used at
last change.Caution
Wipe off any spilled engine oil
immediately.
Caution
Overfilled engine oil must be
drained or suctioned out. If the oil
exceeds the maximum level, do
not start the vehicle and contact a
workshop.
Capacities 3 294.
Fit the cap on straight and tighten it.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
cold regions with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 279.
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

234Vehicle carethe 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.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 279.
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 fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 279.

280Service and maintenanceDexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 284.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use 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
3 284.
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 3 284.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. 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.
