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, therefore 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 the MENU button 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 the SET/CLR button to reset.
Therefore 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
and filter changed by a workshop
within one week or 300 miles
(whichever occurs first).

Control indicators The control indicators described are
not present in all vehicles. The
description applies to all instrument
Driving and operating157
■ The stop-start system is notmanually 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 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.Certain settings of the climate control
system may inhibit an Autostop. See
" Climate control " chapter for more
details 3 146.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 154.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several 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 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
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 - 3 109.
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.
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the charge level of the vehicle battery is below a defined level
204Driving and operating
As soon as the natural gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is started-up again. This
will prevent damage to the catalytic
converter (overheating caused by
irregular fuel supply).
If the selector switch is operated
several times within a short time, a
switchover block is activated. The engine remains in the current
operating mode. The block 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 vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This isnecessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.
Fuel for liquid gas
operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
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,
Vehicle care221Engine coolantThe 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 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.
Engine B16DTH: After starting the
engine, set the heating to warmest
temperature and the fan speed to at
least first level for approx. 5 minutes.
This will ensure that the air within the cooling system escapes.
Have the 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.
Service and maintenance265
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 268.
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 3 268.
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.
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.AdBlue
Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 160.
