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, the remaining
oil life duration is displayed in the
Vehicle Information Menu s.
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 off.
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 ensure
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 off.
When the system has calculated that
engine oil life has been diminished,

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
versions. Depending on the
equipment, the position of the control
indicators may vary. When the
122Driving and operating
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During 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 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 3 113.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 119.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 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 84.
Driving and operating145
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,
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 illu‐
minates=liquid gas operationLED
flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
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 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.
Seek the assistance of a workshop in the event of all other faults.
Vehicle care153Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
Insert dipstick to the stop on the
handle and make half a turn.
Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 206.
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 level
Caution
Too low a coolant level can cause engine damage.
154Vehicle care
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 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 ofthe 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.
196Service and maintenance
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
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 3 199.
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.
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.
