Service display
Service display is available in
vehicles with Multifunction version of
the Driver Information Centre 3 80.
When the ignition is switched on, the remaining distance before the next

on driving conditions, the interval at
which a service will be indicated can
vary considerably.
When the remaining distance before
the next service is less than
1,250 miles, Serv. appears in the
Driver Information Centre. The service reminder is repeated after every additional 125 miles and
becomes more frequent when the
remaining distance is below
125 miles.
The vehicle needs a service. Seek the
assistance of a workshop.
The remaining distance to the next
service may also be viewed in the
Driver Information Centre by
selecting SERVICE from the settings
menu options 3 80.
Resetting the service display After a service, the service displaymust be reset by a workshop.

During an Autostop, the heating,
power steering and brake
performance will be maintained.Caution
The steering assist can be
reduced during an Autostop.
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 and the driver's seat belt is fastened
■ the 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 not too low
■ the climate control system allows an Autostop
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
■ the brake vacuum is sufficient
■ the windscreen wipers are not operating at fast speed
■ reverse gear is not selected
■ heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an Autostop.
For manual transmission automated
vehicles, an Autostop may be
inhibited until a speed of approx.
6 mph is reached.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 103.Battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Restarting the engine
Manual transmission
The selector lever must be in neutral
to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the
brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the
key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.

Accessories and vehicle
modifications
We recommend the use of genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or
guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir.
■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park the vehicle in a dry, well ventilated place. Engage first orreverse gear to prevent the vehicle
from rolling.
■ Do not apply the parking brake.
Vehicle care127
■ Open the bonnet, close all doorsand lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are
not functional, e.g. anti-theft locking
system.
Putting back into operation When the vehicle is to be put back into
operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir. ■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plates if necessary.End-of-life vehicle
recovery Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our
website. Only entrust this work to an
authorised recycling centre.
Natural gas vehicles must be recycled by a service centre authorised for
natural gas vehicles.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
Vehicle care129Caution
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.
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 3 171.
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.
130Vehicle care
If the cooling system is cold, the
coolant level should be between the
MIN and MAX 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.
Power steering fluid
If the fluid level in the reservoir falls
below the MIN mark consult a
workshop.
If an unusual noise sounds during
steering or the power steering reacts
conspicuously, seek the assistance of 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.
Service and maintenance163
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity
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 3 165.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze Use only 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 lowtemperatures 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.
