Drive in a low engine speed range for each gear as much as possible.Caution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays fuel level in the tank.
Control indicator Y illuminates if the
level in the tank is low.Refuel

Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Engine coolant
temperature gauge
Displays the coolant temperature.

Control indicator W illuminates if the
temperature is too high 3 80,

Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
For physical reasons, the coolant temperature gauge shows the coolant temperature only if the coolant level is adequate.
Engine oil level monitor
The engine oil level monitor is correct
only if the vehicle is parked on a level
surface with a cold engine.

locking of the drive wheels.
1. Depress clutch.
2. Select neutral gear, set selector lever to N.
112Driving and operating
AutostopIf the vehicle is at low speed or
standstill, activate an Autostop as
follows:
■ depress the clutch pedal
■ shift the selector lever to neutral (manual transmission) or N
(manual transmission automated)
■ release the clutch pedal
The engine will be switched off while the ignition stays on if the required
conditions are met.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited.
■ 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 ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an Autostop■ the brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See Climate control chapter for
further information 3 96.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.

176Service and maintenanceRecommended fluids,lubricants and parts
Recommended fluids and
lubricants
Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for diesel engines. If it is unavailable,
engine oils of other listed qualities
must be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 181.
Topping up engine oil
Engine oils of different manufacturers and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 181.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 3 181.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free 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
