Starting after running out of fuel
If the tank on vehicles with a diesel engine was empty, starting
after filling with diesel fuel can take longer than normal – up to

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.

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

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.

TCS reduces engine power to help prevent the drive wheels of front-
wheel drive vehicles losing traction during acceleration. The system
works in the entire speed range in conjunction with ABS. If a
malfunction should occur in the ABS, the TCS will also be out of
action.
TCS helps the vehicle to start moving, accelerate and climb a
gradient in slippery conditions where this may otherwise be
difficult or even impossible.
The TCS is switched on automatically when the engine is started. If
necessary, it may be turned on or off by briefly pushing the button
on the centre console.
When the TCS is off, the warning lamp is lit.
The TCS should normally be left switched on at all times. Only in
exceptional circumstances, when slipping of the wheels is
required, should it be disconnected, for example:
– With compact temporary spare wheel.
– When using the snow chains
– When driving in deep snow or on loose surfaces
– When the vehicle is bogged-down, to free it by rocking it.
The TCS should be switched on again afterwards as soon as
possible.N No

gear or any components affecting the wheels and tyres) could affect the

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.

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.

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.
