Tyre pressure monitoring system 3 150.
Engine oil pressure
I illuminates red.
Illuminates briefly when the ignition is
switched on.Illuminates when the engine is
running
If control indicator I illuminates
when the engine is running
(accompanied by a warning chime):
Stop, switch off engine.Caution
Engine lubrication may be
interrupted. This may result in
damage to the engine and/or
locking of the drive wheels.
1. Depress clutch.
2. Select neutral gear (or move selector lever to N).
3. Move out of the flow of traffic as quickly as possible without
impeding other vehicles.
4. Switch off ignition.
114Driving and operating
During an Autostop, brake
performance will be maintained.
However, brake assist is not available
3 118.
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 and 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 outside temperature is not too low or too high (e.g. below 0 °C orabove 30 °C).
■ the brake vacuum is sufficient.
■ the defrosting function is not activated 3 99.■ the self-cleaning function of the
diesel particle filter is not active
3 115.
■ the vehicle has moved since the last Autostop.
Otherwise an Autostop will be
inhibited.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
Control indicator Ï 3 85 extinguishes
in the instrument cluster when the engine is restarted.
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 vehicle battery is discharged.
■ the engine temperature is too low.
■ the brake vacuum is not sufficient.
■ the vehicle starts to move.
■ the defrosting function is activated 3 99.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during engine restart may be
noticeable.
Fault If a fault occurs in the stop-start
system, the LED in button Î
illuminates, and a corresponding
message appears in the Driver
Information Centre 3 86. Seek the
assistance of a workshop.
Vehicle messages 3 87.
Warning chimes 3 87.
Vehicle care135Engine coolantThe coolant provides freeze
protection down to approx. -28 °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 just above the
MIN mark. Top up if the level is low.9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
If a substantial amount of coolant is
required, it will be necessary to bleed
any trapped air from the cooling
system. Seek the assistance of a
workshop.
If the coolant temperature is too high, control indicator W 3 84 illuminates
red in the instrument cluster, together
with C 3 82. Consult a workshop if
coolant level is sufficient.
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 or from
entering the reservoir.
The power steering fluid reservoir is located below the front wheel arch,
behind a trim panel.
The fluid level normally does not need
to be checked. If an unusual noise is
heard during steering or if the power
steering reacts conspicuously, seek
the assistance of a workshop.
166Service 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 petrol and 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
3 171.
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
3 171.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 3 171.
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
