Properties of RME
•RME is chemically produced from vegetable oil (predominantly
rapeseed oil) in a process whereby the oil is mixed with methanol
and converted, via a catalyst, into RME.
•RME is almost totally sulfur free. The combustion of RME thus
emits practically no sulfur dioxide (SO
2).
•Exhaust gas contains less
– carbon monoxide
– hydrocarbons
– particles (i.e. soot)
than with conventional diesel fuel.
All emission values are lower than legal requirements.
•RME fuel is biodegradable.
•Performance may be slightly lower.
•Fuel consumption may be slightly higher.
•RME can be used in temperatures down to approximately –10 °C.
•Diesel fuel must be added at ambient temperatures of less than
–10 °C to prevent deterioration to the biodiesel. The mixing ratio
of diesel to biodiesel must be approximately 50:50.

•During the summer months, RME may be mixed with diesel at
any ratio.
K
Driving in winter
When using summer Diesel trouble may be experienced at
temperatures below
0 °C because the fuel thickens due to wax separation.
For this reason winter Diesel which is more resistant to cold is sold
during the winter in some countries, and this works correctly down
to between –15 °C and –22 °C approximately, depending on the
brand of fuel used.
The biodiesel available in countries with different climactic
conditions usually has different temperature characteristics.
Technical Service Centres or service stations in each country can
inform you of the specific characteristics of the respective diesel.
K
Filter preheating
The vehicle is fitted with a filter preheater. This will ensure that the
fuel system will remain operational down to about –25 °C,
provided that winter Diesel which is cold resistant down to –15 °C
is used.
If, at temperatures below –25 °C the fuel is waxed to such an
extent that the engine will not start it is sufficient to place the
vehicle in a warm enclosure for a while.

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 inflation pressures are to be found inside the fuel lid.
The inflation pressure is very important particularly at high speeds.
Therefore, the pressures should be checked at least once a
month and before every long journey.
At this opportunity do not forget the spare wheel:
• The spare wheel with normal tyre should always be inflated to
the highest pressure required on the vehicle.• Always check the pressures when the tyres are cold. When warm,
the pressure is higher but do not reduce. If the load changes a
great deal the pressure must be altered to suit.
On vehicles with wheel hub caps, valve extensions are fitted. It is
not necessary to remove the valve extension piece in order to test
and correct the inflation pressure.

vehicle is running various influences can cause the wheels to
become unbalanced and this causes steering vibration.

Please note regulations to this effect in your country.
• All-weather tyres can also be used instead of winter tyres.
• If you have a flat tyre the remarks on using the spare wheel on
page 174 should be noted.
• Do not leave winter tyres fitted for an unnecessary long period
because when the roads are free of snow and ice the handling with
summer tyres is better.

For environmental reasons summer tyres should be fitted again as soon as
possible because normally they are quieter in running, tyre wear is reduced
and the fuel consumption is lower.
K
Snow chains
Snow chains can only be fitted on the front wheels.
The use of snow chains is permitted on 155/80 R 13, 165/70 R 14
and 185/60 R 14 tires.

When using snow chains wheel rim plates and rim rings must be
taken off. In this case, to protect the wheel, the bolts must then be
fitted with caps which are available from Technical Service Centres.When driving over roadswhich are free of snow you must remove
the chains. On such roadsthey are detrimental to vehicle handling,
damage the tyres and wear out quickly.
In some countries the maximum permissible speed with snow
chains is 50 km/h.

Preparation work
– In case of a flat tyre or puncture, park the vehicle as far as
possible away from the traffic flow. If necessary, switch hazard
warning lights on and place the warning triangle in position – note
any statutory requirements.
– All vehicle occupants should leave the vehicle and move to a
safe area (e.g. behind safety barrier).
– Apply handbrake firmly, engage a gear or place the gear selector
in position “P” and chock the opposite wheel with a stone or
similar.
– When towing a trailer, the trailer must first be disengaged from
the towing vehicle before the wheel is changed.
– Take tools and spare wheel out of luggage compartment.

correct for unloaded vehicles with basic fittings. If there are extra
fittings, the empty weight will increase and, as a result, the weight

Consult a Technical Service Centre to find out the exact specifications of
your vehicle.
• Driving style, road and traffic conditions, weather conditionsand the
condition of the vehicle will, in practice, produce consumption levels
different to those indicated.
