Service display
Service display is available in
vehicles with Multifunction version of the Driver Information Centre 3 88.
When the ignition is switched on, the remaining distance before the next
service is due may be shown briefly.
Based 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.
When the remaining distance has
reduced to zero, a warning message, e.g. Service coupon expired , appears
in the Driver Information Centre.
The vehicle needs a service. Seek the
assistance of a workshop.
The remaining distance to the next
service may also be viewed in the

Vehicle care137Caution
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, wellventilated place. Engage first or
reverse gear to prevent the
vehicle from rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and 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.
140Vehicle care
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 3 184.
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 level
Caution
Too low a coolant level can cause engine damage.
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
approved coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
Vehicle care141the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Coolant and antifreeze 3 173.
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/dipstick or
from entering the reservoir.
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 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.
Use of washer fluid containing
isopropanol can damage exterior
lamps.
Washer fluid 3 173.
Brakes A squealing noise, or illumination of
brake pad wear control indicator F
indicates that the brake lining is at its
minimum thickness.
Continued driving is possible but
have the brake linings replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake pad wear indicator F 3 82.
