bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds (for technical reasons
only 30 seconds are possible with
engine A 17 DTS). Repeat this
process after no less than 5 seconds .
If the engine fails to start, seek the
assistance of a workshop.Wiper blade replacement

lever down and release as soon as
the wipers are vertical.
174Vehicle careTyre pressure monitoring
system The vehicle may be fitted with a tyrepressure monitoring system or a tyre
deflation detection system 3 175.Caution
Modifications made to the tyre
pressure monitoring system
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
system.
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.
Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and the control indicator A illuminates
continuously.
If A lights up, stop as soon as
possible and inflate the tyres as
recommended 3 217.
After inflating, driving may be
required to extinguish A.
If A lights up at lower temperatures
and extinguishes after some driving,
this could be an early indicator for getting low pressure. Check tyre
pressure.
The tyre pressure monitoring system
malfunction indicator is combined
with the low tyre pressure controlindicator. If the system detects a
malfunction, the control indicator will
flash for approx. 1 minute and then
remain continuously illuminated. This sequence will continue upon
subsequent vehicle start‐ups as long as the malfunction exists.
A temporary spare wheel is not
equipped with a pressure sensor. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator A illuminates.
Operating electronic devices or being
near facilities using radio wave
frequencies similar to the tyre
pressure monitoring system could
cause the tyre pressure monitoring
system sensors to malfunction.
Tyre pressure monitoring system malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent the tyre pressure monitoring system fromfunctioning properly. Always check
the tyre pressure monitoring system
malfunction control indicator after
replacing one or more tyres or wheels
Vehicle care175
on your vehicle to ensure that the
replacement or alternate tyres and wheels allow the tyre pressure
monitoring system to continue to
function properly.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved repair kits can be used.
System initialisation After a wheel change or tyre pressure
adjustment the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
document 3 217. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. The
control indicator A flashes three
times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the
vehicle starts moving for the first time after initialisation. Adjust tyre
pressure and repeat initialisation.Notice
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
16 mph.
Tyre deflation detection
system The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates red. Stop
immediately and check tyre pressure.
Control indicator w 3 83.

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for your vehicle is available
at the workshop.
European service intervals
Service is due every 20000 miles or
1 year, whichever occurs first.
The European schedule is valid for
the following countries:
Andorra, Austria, Belgium, Bosnia-
Herzegovina, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany,
Greece, Greenland, Hungary,

The international service intervals are
valid for the countries which are not listed in the European service
intervals.
Confirmations
Confirmation of service is recorded in
the Service and Warranty Booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
Warranty Booklet is completed
correctly as continuous proof of
service is essential if any warranty or
goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service and maintenance195
Fixed service intervalWhen service is due, InSP appears in
the odometer display for approx.
10 seconds when the ignition is
switched on. Have the next service performed by a workshop within
one week or 300 miles (whichever
occurs first).
Flexible service interval The service interval is based on
several parameters depending on
usage and calculated using these
parameters.
If the remaining distance is less than
1000 miles, InSP is displayed with a
remaining distance of 600 miles when
the ignition is switched on and off. If
less than 600 miles remain, InSP is
displayed for several seconds. Have
the next service performed by a
workshop within one week or
300 miles (whichever occurs first).Display of remaining distance:
1. Switch off ignition.
2. Briefly press the trip odometer reset button. The odometer
reading is shown.
3. Press and hold the reset button for
approx. 2 seconds. InSP and the
remaining distance are displayed.Recommended 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
specifiations 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
196Service and maintenance
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
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
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
3 199.
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 3 199.
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
northern countries 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.
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.
