Front airbags
Description of the front airbags
The airbag system is not a substitute for the seat belt!
The front airbag for the driver is housed in the steering wheel ⇒fig. 161 .
The front airbag for the front passenger* is housed in the dash panel
above the storage compartment ⇒fig. 162 . The installation positions are
each marked with the “AIRBAG” logo.
The front airbag system, in combination with three-point safety belts,
offers additional protection for the head and chest area of the driver and
front passenger in the event of a frontal collision of major severity ⇒ in
“Important safety information regarding the front airbag system” on
page 194.
The airbag is not a substitute for the seat belt, but is part of the complete
passive vehicle safety concept. Please note that an airbag can only
offer you optimal protection in combination with a seat belt which is
fastened. .
Apart from their normal protective function, a further task of the seat belts
is to also hold the driver and front passenger in a correct seated position
in the event of a frontal collision so as to enable the front airbags to offer
the maximum protection.

The first 1 500 kilometres and then
afterwards
A new engine
The engine has to be run in during the first 1 500 kilome-
tres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear
in use, that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the
full speed of the gear engaged, that is up to the maximum
permissible engine revolutions.
During the first operating hours the engine has higher internal friction than
later until all of the moving parts have harmonized. The driving style which
you adopt during the first approx.1 500 kilometres plays a decisive part in
the success of running in your car.
You should not drive at unnecessarily high engine revolutions even
after the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revo-
lutions counter. Shift up into the next higher gear on a vehicle fitted with
manual gearbox before the red zone is reached.
Extremely high engine
revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also
applies: Do not drive at engine revolutions which are too low. Shift down
as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is
at its normal operating temperature. Never rev up an engine which is cold,
neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a
higher gear as early as possible are ways to minimise fuel consumption
and operating noise levels and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
You should take account of this fact for the first 500 kilometres and drive
particularly carefully.

New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pres-
sure on the brake pedal.
This guideline also applies to any new brake pads installed at a future
date.
During the running-in period, you should avoid excessive stresses on the
brakes. This includes, for example, violent braking, particularly from very
high speeds, and also when crossing mountain passes.
Catalytic converter
Proper operation of the emission control system (catalytic
converter) is of major significance for driving your vehicle
in an environmentally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒page 242, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 252, “Replen-
ishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 286, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not avail-
able, you must have the catalytic converter replaced later when driving the
vehicle into a country in which use of a catalytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the
catalytic converter, one should always park a vehicle in such a way
that the catalytic converter cannot come into contact with easily
flammable materials below the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protec-
tion agents for the exhaust pipes, catalytic converters or heat
shields. Such substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular fuel supply can result
in poor ignition or misfiring. Unburnt fuel may get into the exhaust system
and damage the catalytic converter.
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•If you detect misfiring, a drop in performance or irregular engine
running when driving, reduce your speed immediately and have the
vehicle inspected by the nearest specialist garage. The symptoms
described may be caused by a fault in the ignition system. Unburnt fuel
may get into the exhaust system and damage the catalytic converter.

For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust
odour may be produced under certain operating conditions of the engine.
This depends on the sulphur content of the fuel. It is often sufficient to
refuel with unleaded premium-grade petrol of a different brand or at a
different filling station.
Driving in an economical and
environmentally conscious manner
General
Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-
and-tear to the engine, brakes and tyres, depend essentially on three
factors:
•your personal style of driving,
•the conditions under which your vehicle is operated,
•technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving
in an economical way with foresight. This section is intended to provide
you with a number of tips on how to protect the environment and at the
same time save money.
The fuel consumption can naturally also be influenced by factors which
are beyond the driver's control. It is, for example, normal for the fuel
consumption to increase in winter and under worsened conditions such as
poor road conditions, towing a trailer, etc. The technical requirements for low fuel usage and economic efficiency of
the vehicle have already been built into the vehicle at the works. Special
attention has been given to minimising negative effects on the environ-
ment. It is necessary to take note of the guidelines given in this chapter in
order to make best use of these characteristics and to maintain their
effectiveness.
Looking ahead when driving
A vehicle's highest fuel consumption occurs when it accel-
erates.
Avoid accelerating and braking unnecessarily. If you drive with forsight
you will not need to brake so often and will also then not have to accel-
erate so much. Let your vehicle coast to a stop, for example, if this is
possible, when you see that the next set of traffic lights is at red.

Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first
gear.
– Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it
beyond the kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You
will consume more fuel if you drive at unnecessarily high revolutions in
any given gear. The
⇒fig. 183 shows the ratio of fuel consumption to the speed of your
vehicle for the individual gears. Fuel consumption in 1st gear is the
highest, while that in 5th or the 6th gear is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an
automatic gearbox in order to automatically select an economic driving
programme. You will achieve good fuel economy by shifting up early and
shifting down late.

Sensitive use of the accelerator will not only significantly reduce fuel
consumption but also positively influence environmental pollution and
wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever
possible. Fuel consumption, pollutant emissions and vehicle noises
increase disproportionally at high speeds.
The
⇒page 224, fig. 184 shows the ratio of fuel consumption to the speed
of your vehicle. You will cut your fuel consumption by half if you only make
use three-quarters of the possible top speed of your vehicle.
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at
a level crossing or at traffic lights with a lengthy red phase. Even after just
30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal
operating temperature. Wear-and-tear and pollutant emissions, though,
are particularly high in the warming-up phase. This is why you should
drive off right after starting the engine. Do avoid high engine revolutions
at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high
amount of fuel.
Having your vehicle serviced regularly at a specialist garge enables you
to satisfy one of the requirements for economical motoring even before
you set off on your journey. Keeping your vehicle properly serviced not
only has a positive effect on the safety of your vehicle and maintaining its
value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10%
higher than normal.
The foreseen maintenance work should be undertaken exactly according
to the Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to
a considerable extent on the load and speed of the engine. Oil consump-
tion could be as high as 0.5 litres/1 000 km depending on your style of
driving.
It is quite normal that a new engine has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption of a new vehicle
until after you have driven about 5 000 km.
For the sake of the environment
•You can achieve additional improvements in your fuel economy by
using high-lubricity oils.
•Check the ground below your car at regular intervals to detect any
leakages in good time. Please have your vehicle inspected by a specialist
garge if you find any stains caused by oil or other fluids on the floor.

Avoid driving short distances
Short distances result in an above-average high fuel
consumption.
– Avoid driving a distance of no more than 4 km if the engine is
cold.
The engine and catalytic converter must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 10 litres/100 km
after just 1 kilometre. The engine reaches its operating temperature
(outside temperature and engine dependent) only after about 4 to 10 kilo-
metres and the fuel consumption then stabilizes. You should therefore
avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature.
The ⇒fig. 185 shows the different fuel consumptions for the same
distance, on the one hand at +20°C and on the other hand at -10°C. Your
vehicle has a higher fuel consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all
times. The rolling resistance will be increased if the tyre filling pressure is
too low. This will not only increase fuel consumption but also tyre wear
and the driving behaviour will worsen.
Always check the inflation pressure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 %
more fuel. Winter tyres are also louder.
No unnecessary ballast
Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel
consumption means that it is worth taking a look in the luggage compart-
ment to avoid transporting any unnecessary ballast.
It is particularly in town trafffic, when one is accelerating quite often, that
the vehicle weight will have a significant effect upon the fuel consumption.
A rule of thumb here is that an increase in weight of 100 kilograms will
cause an increase in fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of conven-
ience, although you no longer need it. The increased aerodynamic drag of

your vehicle causes it to use about 10 % more fuel than normal at a speed
of 100 - 120 km/h, even when you are not carrying a load on the roof
rack.
Saving electricity
Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer
need them.
When the engine is running, the alternator generates and supplies elec-
trical power. The greater the load on the alternator as a result of having a
large number of electrical components switched on, the more fuel will be
consumed for operating the alternator.
Keeping a log of your fuel consumption
If you really wish to keep a close check on your fuel consumption, it is
best to enter the figures in a logbook. This does not take much time but is
a very worthwhile exercise. It enables you to detect any change (positive
and negative) at an early stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on
how, where and in what conditions you have driven the vehicle since you
last refuelled.
