Running-in
During the first few operating hours the engine internal friction is
higher than later on when all the moving parts have bedded down.
How well this running-in process is done depends to a
considerable extent on the way the vehicle is driven during the first
1,500 km.

Up to 1,000 kilometres
the following general rules apply:

•Trailer towing should if possible be avoided.
From 1,000 – 1,500 km
The speed can be gradually increased to the road or engine

During and after the running-in period the following
applies:
•Do not overrev the engine when cold – either in neutral or in the
gears.

Do not drive with the engine speed unnecessarily high – changing up
early helps to save fuel, reduces noise and protects the environment⇒"Environment friendly and economical driving" chapter.
•Do not let engine labour – change down when engine no longer

is of great importance for the environment-friendly functioning of
your vehicle.
Therefore, keep in mind the following points:
•Versions with a catalytic converter must only use unleaded fuel
⇒"Filling the tank" chapter.
•In vehicles with a catalytic converter never drive until the fuel
tank is completely empty. Irregular fuel supply can cause misfiring,
thus allowing unburned fuel into the exhaust system which can
cause overheating and damage to the catalyst.
•If you experience starting difficulties, loss of power or engine
problems while driving, the cause could be a failure in the ignition.
In this case, fuel may be entering the exhaust system withoutburning and, in this way being released into the atmosphere.
Furthermore, the catalyst could deteriorate due to overheating.
Reduce speed immediately. Have this problem fixed at the nearest
Technical Service Centre.
•Do not overload the engine with oil
⇒"Engine oil" chapter.
•Do not towstartthe vehicle for more than 50 m
⇒"Tow
start/towing" chapter.
N No

te
e
Even when the cleaning system for exhaust fumes is in perfect working
order, under certain circumstances, the fumes may smell like sulfur.
This depends on the percentage of sulfur in the fuel.
Often it is sufficient to change brands or buy super unleaded.

General notes
Three factors determine the fuel consumption, the burden on the
environment and the wear on the engine, brakes and tyres:
•The personal driving style.
•The individual conditions of the use of the car.
•Technical prerequisites.
The fuel consumption can be reduced by 10 to 15 percent by
adopting a thoughtful and economic driving style. This chapter will
help you lower pollution and save money by following 10
suggestions.
K
Suggestion 1. Thoughtful driving style
The highest fuel consumption takes place during acceleration. If
you drive in a thoughtful manner you will have to brake less and,
therefore, accelerate less. You can also let the vehicle roll, i.e.
when you can foresee that the following traffic light will be red.
K
Suggestion 2. Changing gears saves energy
Another way to save fuel is to change up as quickly as possible. If
you drive with high engine revs the car will use up more energy.
The fig. 100shows the relation between the consumption (l/100
km) and speed (km/h) in first, second, third, fourth and fifth gear.
The following rules may be helpful. Never drive more than a few
meters in first gear. When you reach 2,000 revolutions, you should
change up.
If you drive a vehicle with an automatic gearbox, press the
accelerator pedal gently. Do not press it to the kick-down position.
This way, a consumption oriented program is automatically
selected. It changes up as soon as possible and takes longer to
change down.

Suggestion 3. Avoid driving at maximum speed
Try not to drive at maximum speed. The increase of fuel
consumption, exhaust pollution and noise is disproportionate at
high speeds.
The illustration shows the relation between consumption (l/100
km) and speed (km/h)
⇒fig. 101.
If only about 3 quarters of top speed is utilized, the fuel
consumption will be reduced by about half.
Suggestion 4. Decrease idling
It is worth switching off1)the engine in traffic jams, at railroad
crossings and at traffic lights with a long red light. The savings in
fuel after 30-40 seconds with the engine switched off is higher
than the fuel used to switch the engine on again.
K
Suggestion 5. Periodic revisions
Your fuel savings are guaranteed even before going on a trip with
periodic revisions by your Technical Service Centre. Proper engine
maintenance is not only a safety and maintenance issue but also a
fuel consumption issue.
Poor fine tuning of the engine may increase fuel consumption by
up to 10%.
Check the oil level every time you fill up. The oil consumption
depends largely on the engine load. Depending on the driving
style, the oil consumption can be up to 1.0 l/1000 km.
Another suggestion: You can also lower oil consumption by using
synthetic oils.

Suggestion 6. Avoid short drives
The engine and the catalytic converter must reach its optimum
functioning temperature in order to effectively reduce consumption
and toxic gas emissions.
The fuel consumption of a cold engine of a normal vehicle right
after the start is about 30-40 liters per 100 km. After about one
kilometer the consumption decreases to 20 liters. After about
f fo
ou
ur
r
kilometers the engine has warmed up and the consumption is
normal. For this reason, it is important to avoid short drives and
heating the vehicle’s engine when the vehicle is not moving. Drive
on quickly!
The ambient temperature also counts. The illustration shows the
difference in consumption (l/100km) for the same distance (km) at
+20°C and –10°C. Your vehicle’s consumption is higher in the
summer than in the winter
⇒fig. 102.K
Suggestion 7. Check the tyre pressure
Make sure that the tyres have always adequate pressure. Even half
a bar less increases the level of fuel consumption by 5 percent. If
the pressure is not correct, the tyres wear out faster due to an
excessive deformation and overheating which, in turn, will
decrease the driving performance.
Always check the tyre pressure when the tyre is cold.
In addition, do not drive year round with winter tyres. They make
more noise and increase fuel consumption by 10 percent. Change
to summer tyres on time.
K
Suggestion 8. Avoid unnecessary weight
Apart from driving habits and periodic revisions of your vehicle,
there are other ways to reduce fuel consumption:

Every kilogram increases fuel consumption. For this reason, it is
worth checking your boot to avoid unnecessary weight.
Frequently, the roof rack will stay on the roof even though it is no
longer needed. Due to greater air resistance, an unloaded roof
rack at a speed of 100-120 km/h increases the consumption by
approx. 12%.

Suggestion 9. Save electricity
The alternator generates electricity while driving. The more
electricity is used, the higher the fuel consumption.
The heated rear window, extra lights, the heater fan and air
conditioning* use a large amount of energy. The heated rear
window creates a consumption of approx. one liter for every 10
hours.
For this reason, disconnect electrical consumers as soon as they
are no longer needed. The alternator generates electricity when the
engine is running.
K
Suggestion 10. Written check-up
If you wish to reduce fuel consumption keep a trip book. It is not
much work and is worth while since it allows you to detect possible
consumption variations (positive or negative) on time and
intervene, if necessary. If you detect an increase in consumption
you should examine the driving conditions since the last filling.

What do you need to bear in mind when towing a trailer?
The vehicle is designed mainly to carry people and luggage.
However it may also be used to tow a trailer, as long as you fit it
with the technically appropriate equipment and you do not
exceed the maximum authorised weights
⇒“Technical Data”
chapter.Towing a trailer not only demands more from the car, but from the
driver too.
You should therefore strictly adhere to the service and running-in
instructions on the following pages.

•If the trailer to be towed has a 7-pin plug, an adapter cable can
be used which may be obtained in any Technical Service Centre.
Installation of a towing bracket at a later stage should be carried
out according to the instructions of the towing bracket
manufacturer.

•The removable ball coupling of the towing bracket* may be
stored in the tool box located inside the spare wheel recess.
•Additional mirrors are required if the traffic behind the trailer is
not visible with the exterior mirrors fitted as standard. Both exterior
mirrors must be attached to brackets in such a way that a sufficient
field of vision to the rear is guaranteed at all times.
•The permitted trailer weight must not be exceeded under any
circumstances
⇒chapter “Technical Data”.
•In vehicles equipped with air conditioning, the factory
installation provides reinforced cooling system to account for the
fitting of a towing device.

142Your vehicle and the environment
•In vehicles without air conditioning, the cooling system should
be reinforced if a towing device is fitted at a later stage.
Failure to do so will submit the engine to greater stress (steep
slopes, high temperatures, heavy towing loads, etc.) and result in
overheating of the engine. For more information, contact a
Technical Service Centre.
•When using a trailer on mountain routes you must bear in mind
that the tow loads given in the “Technical data” chapter are only
applicable for slopes of 10% to 12%. If you do not use the full tow
load you may drive up steeper slopes.
•The given trailer weights are only applicable for altitudes up
to 1000 m above sea level. As the engine output drops due to
the decreasing air density, the climbing ability must also be
reduced by 10% for each further 1000 m.
•Where possible make full use of the maximum permissible
drawbar weight on the ball of the towing bracket but do not exceed
it
⇒chapter “Technical Data”.
•While observing the permissible trailer and drawbar weight,
distribute the load in the trailer so that heavy objects are as near
as possible to the axle. The objects must also be secured so that
they cannot slip about.
•The tyre pressures on the towing vehicle must be adjusted for full
load conditions, and also check the pressures on the trailer.
•Headlight settings should be checked, with the trailer attached,
before beginning the journey and adjusted as necessary.
On vehicles with headlight beam control it is only necessary to turn
the knurled disc on the dash board in the appropriate direction.D Dr

To obtain the best possible handling of vehicle and trailer, the
following should be noted:
• Try to avoid driving with an unladen vehicle and a loaded trailer.
If this cannot be avoided, only drive slowly to allow for the
unfavourable weight distribution.
• As driving stability of vehicle and trailer decreaseswhen the
speed increases do not drive at the maximum permissible top
speed in unfavourable road, weather or wind conditions –
particularly when going downhill.
In any case the speed must be reduced as soon as the trailer
shows the slightest sign of snaking. On no account try to stop the
snaking by accelerating.

• Always brake in good time. If the trailer has an overrun brake,
apply the brakes gently at first then firmly. This will avoid the
jerking caused by the trailer wheels locking.
Change down before going down a steep hill so that the engine
can act as a brake.
• When a long climb in a low gear with extremely high engine revs
must be negotiated at exceptionally high ambient temperatures
the coolant temperature gauge must be observed. When the gauge
needle moves to the right end of the scale, the road speed must be
reduced immediately.
• The cooling effect of the radiator fan cannot be increased by
changing down, because the speed of the fan is not dependent on
