Technical Data
Auto Check ControlCar stateThe Auto Check Control carries out a check of certain functions and vehicle compo-
nents. The check is performed constantly when the ignition is switched on, both
when the vehicle is stationary, as well as when driving.
Operational faults, urgent repairs, service work or other information appear in the
display of the instrument cluster. The disp lays are shown with a red or yellow light
symbol depending on the priority of the message.
The red symbols indicate danger (priority 1) while the yellow symbols indicate a
warning (priortity 2). Information for the driver may also appear in addition to the
symbols ⇒page 27.
Investigate the displayed faults as soon as possible. If several operational faults
exist at the same time, the symbols will appear one after the other and are each
visible for about 2 seconds.
The error messages are faded out after 10 seconds or by actuating the rocker switch ⇒ page 24, fig. 26 and are stored under the information CAR STATUS.
There is at least one error message to be read when the term CAR STATUS is
flashing in the menu. The display will show STATUS 1/2 (for example) if a number
of error messages are present. This display indicates that the first of a total of two
error messages should be displayed.
Actuate the rocker switch , to call up the individual error messages.
If a fault occurs, a warning signal will also sound in addition to the symbol and text
in the display:•
Priority 1 - three warning signals
•

Starting-off and Driving
96•
Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises ma y louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 190.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 193.
WARNING
•
Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
•
Avoid high engine revolutions, full throttl e and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!
•
Vehicles which are fitted with an exhaust gas catalyti c converter should not be
tow-started over a distance of more than 50 metres.For the sake of the environment
Never warm up the engine when the vehi cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol enginesThese engines are fitted with a starter system which selects the correct fuel/air
mixture for every external air temperature.•
Do not depress accelerator before and when starting engine.
•
Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•
It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 194.
•
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel enginesGlow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light
 comes on after the igniti on has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
•
You should start the engine immediately after the glow plug warning light

has gone out.
•
The glow plug warning light will come on for about one 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.
•
Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•
It is possible that the fuse on the dies el preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒page 194.

Driving and the Environment
142The ⇒page 141, fig. 144 shows the ratio of fuel consumption to the speed of your
vehicle. You will cut your fuel consumption by half if you only make use three-quar-
ters of the possible top speed of your vehicle.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 length y red phase. Even after just 30 - 40 seconds
you will have saved more fuel than 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 em issions, 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 revolutions 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 servic ed not only 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 consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine ha s a higher oil consumption at first, and
reaches its lowest level only after a cert ain running in time. It is therefore not possible to correctly assess the oil cons
umption of a new vehicle until after you
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 car at regula r intervals to detect any leakages in
good time. Please have your vehicle inspected 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 the 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 emis-
sions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel consumption 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
stabilizes. You should therefore avoid driving short distances whenever possible.
