Glow plug system
(diesel engine)
The warning light
lights up for a
cold
engine when switching on the ignition (pre-
heat position)
page 89. Start the engine after the indicator light goes out.
The glow plug indicato
r light will come on for about 1
second if the engine is at a
normal operating temperature
or if the outside temperature is above +5°C. This
means that you can start the engine
right away
.
There is a fault in the glow plug system if the
warning light
does not come on
or
lights up continuously
; contact a specialist garage as soon as possible to obtain
assistance. If the
warning light
begins
to flash
while driving, a fault exists in the engine
control. The engine management system
selects an emergency programme which
enables you to drive to the nearest specialist garage by adopting a gentle style of driving. The following text will be displayed in the information display*:
Engine fault: Workshop!
Coolant temperature/coolant quantity
The warning light
lights up until the engine reaches operating temperature
3). Avoid
running at high engine speeds, at full
throttle and at se
vere engine loads.
The warning light
comes on for a few seconds when
the ignition is switched on.
The coolant temperature is too high or the
coolant level too low if the warning light
lights up or flashes while driving. An audible signal sounds as a warning signal.In this case stop and switch the engine off
and check the coolant level; top up the
coolant as necessary
page 170, “Replenishing the coolant”.
Do not continue your journey
if for some reason it is not possible under the condi-
tions prevailing to top up with coolant.
Keep the engine switched off
and obtain
professional assistance from a specialist garage, otherwise it could lead to severe engine damage.
If the coolant is within the specified range, the increased temperature may be caused by an operating problem at the coolant fan.
Check the fuse for the coolant fan, replace
it if necessary
page 199, “Fuse assignment at th
e battery (automatic gearbox)”.
If the warning light
does not go out although the coolant is at the correct level and
also the fuse of the fan is in proper order,
do not continue driving
. Contact a specialist
garage to obtain assistance. Please refer to the following guidelines
page 169, “Cooling system”.

Catalytic converterProper operation of the emission cont
rol system (catalytic converter) is
of major significance for driving your vehicle in an environmentally conscious way.Please refer to the following guidelines: – For vehicles with petrol engine only refuel with unleaded petrol
page 162,
“Grades of petrol”.
– Never run the fuel tank completely empty.– Do not switch off the ignition while you are driving the vehicle.– Do not pour too much oil into the engine
page 168, “Replenishing engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
page 193,
“Tow-starting a vehicle”.
If you drive your vehicle in a country in
which unleaded petrol is not available, you
must have the catalytic converter replaced la
ter when driving the ve
hicle into a country
in which use of a catalyti
c converter is mandatory.
WARNING
In view of the high temperatures which may be produced in the catalytic
converter, one should always park a vehicle in such a way that the catalytic converter cannot come into contact with easily flammable materials below the vehicle - a risk of fire!
Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters or heat shields. Such substances might ignite when driving - risk of fire!
Caution
On vehicles fitted with a catalytic converte
r, never let the fuel tank run completely
empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel may get into the exhaust system an
d damage the cata
lytic converter.
Filling the tank even only once with le
aded petrol will resu
lt in the catalytic
converter being destroyed.
If you detect misfir
ing, a drop in performance or
irregular engine running when
driving, reduce your speed immediately and have the vehicle inspected by the nearest specialist garage. The symptoms described ma
y be caused by a fault in the ignition
system. Unburnt fuel may get into the exhaust system and damage the catalytic converter.
For the sake of the environment
Even if the exhaust system is operating pr
operly, a sulphur-like exhaust odour may be
produced under certain oper
ating conditions of the en
gine. This de
pends on the
sulphur content of the fuel. It is often sufficient to refuel with unleaded premium-grade petrol of a different brand or at a different filling station.Driving in an economical and environmentally conscious mannerGeneral Your personal style of driving is a major factor.Your fuel consumption, any pollution of
the environmental and the wear-and-tear to
the engine, brakes and tyres, depend essentially on three factors:
your personal style of driving;
the conditions under which
your vehicle is operated;
technical aspects.
You can easily improve your fuel economy by
10 - 15 percent by driving in an econom-
ical way with foresight. This section is intended to provide you with a number of tips on how to protect the environment and at the same time save money. The fuel consumption can naturally also be
influenced by factors which are beyond the
driver's control. It is, for example, normal
for the fuel consumption to increase in
winter and under worsened cond
itions such as poor road conditions, towing a trailer,
etc. The technical requirements for low fuel usage and economic efficiency of the vehicle have already been built into the vehicle at the works. Special attention has been given to minimising negative
effects on the environment. It is
necessary to take note of the

Reducing idling Idling also costs fuel.It is worthwhile switching off the engine in
a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 seconds you will have saved more fuel th
an that is needed when you start the engine up again.
If an engine is only idling it takes much
longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emis
sions, though, are particularly high in
the warming-up phase. This is why you should drive off right after starting the engine. Do avoid high engine revolu
tions at this time, however.
Regular servicing A poorly tuned engine consumes an unnecessarily high amount of fuel.Having your vehicle serviced regularly at a specialist garge enables you to satisfy
one
of the requirements for economical motoring even before you set off on your journey. Keeping your vehicle properly serviced not on
ly has a positive effect on the safety of
your vehicle and maintaining its value, but also saves on
fuel
.
A poorly tuned engine can result in a fu
el consumption which
is 10% higher than
normal. The foreseen maintenance work should be
undertaken exactly according to the
Service schedule by a specialist garage. Also check the
oil level
after refueling.
Oil consumption
is dependent to a consider-
able extent on the load and speed of the en
gine. Oil consumption co
uld be as high as
0.5 litres/1 000 km depending on your style of driving. It is quite normal that a new engine has a
higher oil consumption
at first, and reaches
its lowest level only after a certain running in time. It is therefore not possible to correctly assess the oil consumption of a new
vehicle until after yo
u have driven about
5 000 km.
For the sake of the environment
You can achieve additional
improvements in your fuel economy by using high-
lubricity oils.
Check the ground below your vehicle at regular intervals to detect any leakages in
good time. Please have your vehicle inspec
ted by a specialist garge if you find any
stains caused by oil or other fluids on the floor.Avoid driving short distances Short distances result in an above-average high fuel consumption.– Avoid driving a distance of no more
than 4 km if th
e engine is cold.
The engine and catalytic converter mu
st first have reached their optimal
operating
temperature
in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle cons
umes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel co
nsumption drops to 10 litres/100
km after just 1 kilometre. The
engine reaches its operating temperat
ure (outside temperature and engine
dependent) only after about
4 to 10
kilometres and the fuel consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature
. The
fig. 135
shows the different fuel consumptions for the same distance, on the one
hand at +20°C and on the other hand at
-10°C. Your vehicle has a higher fuel
consumption in winter than in summer.

Underbody protectionThe underside of your vehicle is protected for life against chemical and mechanical influences. One cannot, however, complete
ly rule out damage to the
protective layer
when
driving so we recommend that you inspect the protective layer on the underside of your vehicle and on the
chassis at certain intervals - this is best done at the beginning
and end of the winter - and to touch up any damaged areas. Specialist garages have suitable
spray products
available as well
as the necessary
equipment and are familiar with the instructions for use. Therefore, we recommend you have such touch-up work or additional
corrosion protection measures carried out
by a specialist garage.
WARNING
Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalytic converters, di
esel particle filter or heat shields.
When the engine reaches its operating
temperature, these substances might
ignite - risk of fire!Protection of hollow spacesAll the cavities of your vehicle which are at risk from corrosion are protected for life by a layer of
protective wax
applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any small amount of wax which flows out of the cavities at high temperatures with a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental pr
otection regulations should observed when using
petroleum cleaner to remove wax - a risk of fire!
Engine compartmentGood corrosion protection is very importan
t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the entire engine compartment before and after the salt spread
ing period, in order to prevent the salt
from being destructive. Specialist garages have the cleaning agen
ts recommended by the manufacturer and
also the required equipment.
WARNING
It is necessary to observ
e the guidelines given in the chapter before working
on the engine compartment
page 166.
Let the engine cool down before cleaning the engine compartment.Caution
Engine cleaning may be only be un
dertaken when the ignition is off.
It is recommended to cover the generator before washing the engine compart-
ment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and residues of grease and oil and should therefore be
cleaned by an oil separator. This is why
engine washing should only be undertaken in garages or at filling stations (when these are fitted with the required equipment).Care of the interior of vehiclePlastic parts, artificial leather and clothsYou can clean plastic parts and artificial le
ather with a moist cloth. You should only
treat such parts with special
solvent-free plastic cleaning and care products
it does
prove to be adequate.
