The glow plug lamp does not come on – the engine can be started
straight away.
K
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
air before starting.

When the engine has been subjected to a heavy engine load for a long
time, the engine must not be switched off abruptly. Let it idle for about 2
minutes to avoid overheating.

Do not switch off the ignition while the vehicle is in motion with a gear
engaged; otherwise unburned fuel may go into the converter, where it
would burn and cause overheating, which would damage the converter.

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.

Releasing tank flap manually
If the central locking system should fail, the flap can be released
manually:
• Open tailgate and – if fitted – fold back the right luggage
compartment trim from side panel.
• Then push the locking rod in front of the white diaphragm
housing backward slightly in direction of arrow
⇒fig. 150.K

In the chapter “Technical Data” and on the inside of the tank flap
you will find information on the correct octane rating for your
engine.

General notes
•Unleaded petrol must comply with DIN EN1)228 and leaded
petrol with DIN 51 600.
•If, in an emergency, the octane rating of the available petrol is
lower than that required by the engine, only drive with medium
engine speeds and low engine loading. H Hi

•Fuel with a higher octane rating than that required by the engine
can be used without limitation. There are, however, no advantages
regarding output and consumption.

In vehicles with front wheel traction, the TCS lowers the engine
power to stop the wheel spinning when you accelerate. This feature
works at any speed in combination with the ABS. If there is an ABS
breakdown, the TCS stops working.
Vehicles fitted with TCS are also fitted with an electronic differential
lock (EDL).
The EDL makes it much easier, or even possible, to pull away,
accelerate and climb steep gradiants in unfavourable conditions.
The EDL works fully automatically – the driver does not need to do
anything at all.
It uses the ABS sensors to monitor the speed of the driving wheels.
Up to a speed of about 80 km/h (50 mph), a difference in speed of
the drive wheels of approximately 100 rpm caused by a slippery
road surface on o on
ne
e ssi
id
de
e
is balanced out by slowing down the
wheel which is slipping and thereby applying more driving force to
the other drive wheel through the differential.

.To ensure that the brake disc of the braked wheel does not
overheat, the EDL will automatically switch itself off if excessive
demands are placed on it. The vehicle remains operational and has
the same characteristics as a vehicle without EDL. For this reason,
the switching off of the EDL is not noticed.
As soon as the brakes have cooled off, the EDL will switch itself
back on again.
If the ABS warning lamp lights up there may be a fault present in
the EDL. Take the vehicle to a Technical Service Centre as soon as
possible!
The TCS connects automatically once the engine is started. If
necessary, it can be connected or disconnected by pressing shortly
the button located on the central console.
When the TCS is switched off a pilot light comes on.
You should normally always have the TCS on. Only in exceptional
circumstances when you want the wheels to spin should you
switch it off. For instance:
– When you are using snow chains.
– When driving in deep snow or on a soft surface.
– When the car is stuck, to “rock” it out, and

After the running-in period
•On vehicles with a rev counter* the maximum permissible engine
speed is shown by the beginning of the red zone on the rev
counter scale. The needle of the counter must not move into this
zone.
Extremely high engine revs will be automatically governed.

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 without
burning 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.

171 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. 153.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%.

• 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.
K
Topping up coolant
Switch engine off and let it cool down. Then cover expansion tank
cap with a cloth and turn cap carefully anti-clockwise and remove.
No other coolant may be used if
G G1

+is not available. In this
case only water can be used and the correct mixture concentration
must be restored with the specified coolant additive (see previous
page) as soon as possible.
