General notes
The filler neck is located in the rear right-side panel.
The fuel tank cap turns freely to prevent it’s opening without a key.
Open the cover, hold the cap with one hand and next introduce the
key in the lock and turn it 180° to the left. At this moment the cap
should unscrew in a counter-clockwise direction.To close, screw the cap to the right until you hear a "click". Turn the
key without releasing the cap clockwise 180°. Remove the key and
close the cover.
The tank holds about 45 liters.

As soon as the automatic nozzle, correctly operated, disconnects for the
first time, the tank is full. Do not continue filling since the expansion space
would be occupied. If it heats up the fuel could overflow.
After filling the tank, screw cap and close tank flap until it engages.
The cap is tied to an anti-loss cord.

Any fuel spillage should be wiped off the paint finish immediately, as the
paint could otherwise be damaged, especially if it is RME (“biodiesel”) fuel.

On vehicles with a catalytic converter, never drive until the fueltank is
completely empty. The irregular fuel supply can cause misfiring. This allows
unburnt fuel into the exhaust system, which can cause overheating and
damage to the catalyst.

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.

If one of the wheels is turning too slowly in relation to the road
speed, and is close to locking, the system will reduce the braking
pressure for this wheel. The driver is made aware of this control

and audible noise.This is a deliberate warning to the driver that one or more of the
wheels is tending to lock and the ABS control function has
intervened. In this situation it is important to keep the brake pedal
fully depressed so the ABS can regulate the brake application. Do
not pump the brake pedal.
If you brake hard on a slippery road surface, the best possible
control is retained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking
distances in all conditions. The braking distance could even be
longer if you brake on gravel or on fresh snow covering a slippery
surface.

constantly compares them with the actual behaviour of the vehicle.
If the desired course is not being maintained (for instance, if the
car is starting to skid), then the ESP compensates automatically by
braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a
stable condition. If the vehicle tends to oversteer, the system will
act on the front wheel on the outside of the turn.
N No

•In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radiusof the tyres
can cause the system to reduce engine power when this is not desired.
•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affectthe
efficiency of the ABS, EDL, ESP and TCS.
K
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during
braking
⇒chapter “Anti-lock brake system and traction control
ABS”.
K
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of traction
caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a
gradient in slippery conditions where this may otherwise be
difficult or even impossible.
It uses the ABS sensors to monitor the speed of the driven wheels.
In case of an EDL fault the warning light for ABS lights up
⇒
chapter “Warning lamps”.
At speeds of up to approximately 80 km/h, it is able to balance out
differences in the speed of the driven wheels of approximately 100
rpm caused by a slippery road surface on one side of the vehicle. It
does this by braking the wheel which has lost traction and
distributing more driving force to the other driven wheel via the
differential.
To prevent the disc brake of the braked wheel from overheating,
the EDL cuts out automatically if subjected to excessive loads. The
vehicle will continue to function normally without EDL. For this
reason, the driver is not informed that the EDL has been switched
off.
The EDL will switch on again automatically when the brake has
cooled down.

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

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.

138Your vehicle and the environment
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.

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%.
