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
one minute. This is because the fuel system must first be freed of

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.

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

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.

•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.

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
ot
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.

139 Your vehicle and the environment
Safety FirstControls and equipment Tips and Maintenance Technical Data
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%.

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

• Only our G12+ (purple colour) should be used as an antifreeze additive.
Observe the notice on the container. The cooling liquid may be purchased in
Technical Services.
• The antifreeze additive G12+ can be mixed with other additives (G11 and
G12).
• The additive G12 (red colour) should never be mixed with G11.
K
Checking coolant level
The level can only be checked properly when the engine is not
running.
The coolant level must be between the
m ma
ax
xand m
mi
in
nmarks on the
expansion tank when engine is cold and can be slightly above the
m ma
ax
xmark when it is warm.K
Coolant losses
Coolant loss normally indicates leaks in the system. In this case
the cooling system should be checked by a Technical Service
Center without delay. It is not sufficient merely to add coolant.
In a sealed system losses can only occur if the boiling point of the
coolant is exceeded as a result of overheating, and coolant is
forced out of the system.
