Seat belts
118
The speed of the vehicle is,
nevertheless, the most important factor. Doubling the
speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four times. The common opinion that it is possible to su
pport your body in a minor accident with
your hands, is incorrect. Even in a collision at only a low speed, the forces acting on the body are such that it is no longer possible to support your body. Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body in
the event of an accident can easily exceed
10.000 N (Newton). This equals a weight of one tonne (1 000 kg). In the event of a frontal collision, occupants
of the vehicle not wearing a seat belt, are
thrown forward and strike in an uncontrolled
way parts of the interior of the vehicle,
such as steering wheel,
dash panel, windscreen,
page 117, fig. 110
- left. The occu-
pants of a vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can result in fatal injuries. It is also important that rear seat occupants fasten their seat belts as they will otherwise be thrown through the vehicle in an uncontr
olled manner in the event of an accident
A rear seat passenger who has not fastened the

Important safety information regarding the use of seat beltsThe correct use of the seat belts cons
iderably reduces the risk of injury!
WARNING
The belt webbing must no
t be jammed in-between at any point or twisted,
or chafe against any sharp edges.
It is important that the belt webbing is properly routed if the seat belts are
to offer their maximum protection
page 119, “How are seat belts correctly
fastened?”.
No two persons (also not children) should ever use a single seat belt
together.
The maximum protection which seat belts can offer is only achieved if you
are correctly seated
page 114, “Correct seated position”.
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, keys etc.) as this may be a cause of injuries.
Bulky, loose clothing (e.g. a winter coat over a jacket) does not allow you to
be correctly seated and impairs proper operation of the seat belts.
It is prohibited to use clamps or other objects to adjust seat belts (e.g. for
shortening the belts for smaller persons).
The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety
belt will reduce its capacity to protect
and the risk of injury increases.
The seat backrests must not be tilted too far to the rear otherwise the seat-
belts can lose their effectiveness.
The belt webbing must always be ke
pt clean. Soiled belt webbing may
impair proper operation of the inertia reel
page 161, “Seat belts”.
The slot of the belt tongue must not be blocked by paper or similar objects
otherwise the belt tongue will not lock in place properly.
Inspect the seat belts regula
rly to ensure they are in
good condition. If you
find seat belts which have damage to the seat belt webbing, seat belt connec- tions, to the inertia reels or to the lock,
the relevant safety belt must be replaced
by a specialist garage.
The seat belts must not be removed or changed in any way. Do not make an
attempt to repair the seat belts yourself.
Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a specialist garage. The anchorage points of the
belts must also be inspected. The
anchorage points for the belts should also be checked.
In certain countries it is possible to use seat belts which differ in terms of
their operation from the seat belts wh
ich are described on the pages which
follow.

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 th
an 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 emis
sions, 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 revolu
tions 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 on
ly 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 fu
el 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 consider-
able extent on the load and speed of the en
gine. Oil consumption co
uld 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 therefore not possible to correctly assess the oil consumption of a new
vehicle until after yo
u 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 vehicle at regular intervals to detect any leakages in
good time. Please have your vehicle inspec
ted 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 th
e engine is cold.
The engine and catalytic converter mu
st first have reached their optimal
operating
temperature
in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle cons
umes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel co
nsumption drops to 10 litres/100
km after just 1 kilometre. The
engine reaches its operating temperat
ure (outside temperature and engine
dependent) only after about
4 to 10
kilometres and the fuel consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature
. The
fig. 135
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.

It is normal for the engine to consume oil.
The oil consumption may be as much as 0.5
l/1 000 km depending on your style of driving and the conditions under which you operate your vehicle. The oil
consumption may be slightly hi
gher than this during the
first 5 000 kilometres. One should therefore check the oil level at regular intervals, preferably every time after the fuel tank is filled or after driving for long stretches. We recommend maintaining the oil level within the range if the engine has been operating at high loads, for example duri
ng a lengthy motorway trip during the
summer months, towing a trailer or
negotiating a high mountain pass,
but not above
this
.
The warning light in the instrument cluster* will indicate
page 29 whether the oil
level is too low. In this case, check the oil
level as soon as possible. Top up with an
appropriate quantity of oil.
WARNING
Read and observe the warning notes
page 166, “Working in the engine
compartment” before working in the engine compartment.
Caution
Always check the oil level on vehicles with engine 1.2 ltr./44 kW when the engine is
cold, on other vehicles when the engine is warm. Otherwise the measuring result is incorrect und oil could be incorrectly
replenished - risk of engine damage!
The oil level must on no account extend
beyond the range . Danger of damaging
the catalytic converter.
Do not continue your journey
if for some reason it is not possible under the
conditions prevailing to top up with oil.
Switch the engine off
and obtain professional
assistance from a specialist garage, otherwise it could lead to severe engine damage.Replenishing engine oil– Inspect the oil level
page 167.
– Unscrew the cap of the engine oil filler opening.
– Wipe off the oil from the sealing surface of the cover and on the counterpart using
a clean cloth.
– Pour in a suitable grade of oi
l in portions of 0.5 litres
page 210.
– Inspect the oil level
page 167.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!
Read and observe the warning notes
page 166, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range
page 167. Oil will otherwise
be drawn in through the cr
ankcase ventilation and may
pass through the exhaust
system to atmosphere. The oil may combust
in the catalytic conv
erter and damage it.
Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or according to the service interval indicator
page 17.
WARNING
Only carry out the engine oil change, if you have the required professional
knowledge!
Read and observe the warning notes
page 166, “Working in the engine
compartment” before working in the engine compartment.
First of all, let the engine cool down, we
ar an eye protection and gloves - risk
of caustic burns due to hot oil.
