The ESP increases the control over the vehicle in situations such as
accelerating or in turns.
The ESP expands the functions of the ABS/TCS and decreases
under any circumstance the risk of skidding. This contributes to an
improved stability of the vehicle.The system works in the realm of speed in relation to the ABS. In
case of a failure of the ABS, the ESP will also fail.
The ESP connects automatically when the engine is switched on
and checks itself.
If needed, the system can be switched on or off by pressing the
button.
When the system is off, the ESP warning light will light up
⇒
"Warning lights" chapter.
The ESP should always be connected. Only in exceptional cases,
when the skidding effect is desired under extremely sporty
conditions, the system can be disconnected.
Afterwards the system should be reconnected.
The ABS and EDS
⇒"Switches" chapter remain connected even
when the ESP is off.

The electronic stability program encompasses the ABS, EDS and
TCS. In addition to all available data for these functions, the ESP
control unit needs additional measurements supplied by high
precision sensors. The measuring data consists of the speed at
which the vehicle turns around its vertical axis, acceleration,
pressure on brakes and the turn of the steering wheel.
With the help of the steering wheel sensor and the vehicle’s
speed, the desired direction is determined and constantly
compared to the vehicle’s real behavior. When differences occur,
such as incipient skidding, the ESP automatically brakes the
adequate wheel.

The vehicle stabilizes through the braking force on the wheel. If the
vehicle swings out (tendency of the tail to swing out) the brakes
will act on the exterior front wheel. In case the swerve is
insufficient (tendency to leave the curve) the braking force willbe
exerted on the interior rear wheel The braking generates a noise.P Po

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
1,500 km.

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
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.

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. 151shows 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.

170Your 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. 152.
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. 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%.

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.
K
