The engine oil life system informswhen 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
300 miles, whichever occurs first.
This can be an additional engine oil

Driving and operating181During 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 self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 163.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 176.
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 e.g. auxiliary electric heater
or heated rear window are disabled orswitched to a power saving mode.
The fan speed of the climate control
system is reduced to save power.
Restart of the engine by the driver
Vehicles with manual transmission
All engines can be restarted in two
ways: with a conventional restart or a
late restart.Conventional restart
Depress the clutch pedal without
depressing the brake pedal to restart
the engine.Late restart
Late restart is only available on
inclines up to 5%.
● Depress the brake pedal.
● Depress the clutch pedal.
● Select first gear.
● Release the brake pedal to restart the engine.
Vehicles with automatic transmission Release the brake pedal or moveselector lever out of D into N or P to
restart the engine.
256Vehicle careWe recommend the use of the same
grade of engine oil that was used at
last change.
When 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.
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 3 316.
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 3 300.
Coolant levelCaution
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.
Vehicle care257
Depending on the engine, the
position of the coolant container may be different.
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 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 3 300.
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.
Service and maintenance301Use 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
3 304.
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 on 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 3 304.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
cold regions 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.Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
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 3 185.
