Seat belts
- Do not wear the belt over hard or fragile ob
jects (such as glasses or pens, etc.) because
this can cause injuries.
- Loose, bulky clothing (such as an overcoat
over
a
jacket) impairs the proper fit and
function of the belts.
- The belts must be kept clean, otherwise the
retractors may not work properly
•=>
tab. Cleaning the interior on page 314.
- The slot in the seat belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging
properly.
-The latch plate of the belt must always be
engaged in the correct buckle for that seat,
otherwise the belt will not be fully effective.
- Check the condition of the seat beLts at
reg
ular intervals. If
you
notice that the belt
webbing,
fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced by a qualified work
shop.
- The seat belts must not be removed or
modified in any way. Do not attempt to re
pair
a
damaged belt yourself.
- Seat belts which have been worn in an
acci
dent and stretched must be replaced by a
qualified workshop. The belt anchorages
should also be checked.
Forces acting in a
collision
The physical principles involved in a frontal
impact
Very
large forces are generated during a
colli
sion; these forces have to be absorbed.
Fig.
216 Passengers of
a
vehicle which is headed for a
brick
wall.
They are not using seat belts.
Fig.
217 The vehicle crashes into the wall
The physical principles involved in a frontal
colli
sion are relatively simple:
Both the moving vehicle and the passengers pos
sess energy, which is known as "kinetic energy"
^>Fig.
216. The amount of "kinetic energy" de
pends on the speed of the vehicle and the weight
of the vehicle and passengers. The higher the
speed and the greater the weight, the more ener
gy there is to be absorbed in an accident.
The most significant factor, however,
is
the
speed of the vehicle. If the speed doubles from
25 km/h to 50 km/h, for example, the kinetic en
ergy increases by
a
factor of four. Because these
passengers are not restrained by seat belts, the
entire amount of kinetic energy has to be absor
bed
at
the point of impact
^>Fig.
217. This would
result in serious or potentially fatal injury.

Even
at
urban speeds
of
30 km/h to 50 km/h, the
forces acting on the occupants in a collision can
reach the equivalent
of
1 ton (1000 kg)
or
more.
At greater speed these forces are even higher.
Again:
if
the speed doubles, the forces increase
by
a
factor of four.
Passengers who do not wear seat belts are not
"attached"
to the vehicle. In a frontal collision
they will continue to move forward at the speed
their car was travelling just before the impact.
What happens to passengers not wearing
seat belts?
Passengers
not wearing seat belts risk fatal inju
ries in the event
of
an
accident.

In a frontal collision, unbelted passengers will be
thrown forwards and make violent contact with
the steering wheel, dashboard, windscreen, etc
^Fig.
218. Passengers not wearing their belts
risk being thrown out of the car. This could result
in potentially fatal injuries.
The common belief that occupants can brace
their weight with their hands in a minor collision
is false. Even
at
low speeds the forces acting
on
the body in a collision are so great that
it
is not
possible to hold yourself in the seat.
It is also important for the rear passengers
to
wear seat belts, as they could otherwise be
thrown forwards violently in an accident. Rear
passengers who do not use seat belts endanger
not only themselves but also the other occupants

Seat belts
•
Pull the belt to check that it is now securely fas
tened.
The three-point inertia reel belts are tensioned
automatically. The retractor system gives com
plete freedom of movement, as long as the pull
on the belt is slow. Hard braking locks the belt.
The belt will also lock when you accelerate, drive
up or down a steep hill or corner sharply.
A WARNING
- Always make certain that the belt is
posi
tioned properly
^>Fig.

<=$page
278, Adjusting the seat belts.
- The latch plate of the belt must always be
engaged in the correct buckle for that seat.
Otherwise the belt will not be fully effective
and the danger of injury increases.
Adjusting the seat belts
Always position seat belts properly for maximum
safety.
Fig.
222 Adjusting shoulder/lap belt
The following features allow you to match the
position of the seat belt to your height:
- Belt height adjustment*
- Seat height adjustment (front seats)
/K WARNING
- The shoulder section of the belt should be
fitted across the centre of the collar bone
close to the body. To fasten the belt, take
hold of the belt above the latch plate and
pull it slowly down across your chest. Wear
the lap portion of the seat belt as low as
possibLe over the hips so that there is no
pressure on the lower abdomen. The belt
should always be worn tightly
^>Fig.
222.
Pull the belt tight if necessary to take up
any slack.
-Always make sure that belt is positioned
properly. Incorrectly worn seat belts can
give rise to injuries even in a minor coLlision.
- Seat belts worn too loose can result in
inju
ries because they allow excessive forward
movement in a crash; the occupant will be
brought to a sudden stop by the belt web
bing.

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro
fessional assistance.

A WARNING
Fuel is highly inflammable and can cause
seri
ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to
carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.
- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre
vent an electrostatic charge building up.

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.
(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too
small,
it may not be able to open the pro
tection mechanism on the fuel tank. In this
case,
try turning the filler nozzle before in
serting it in the fuel filler neck, use a differ
ent filling pump or seek professional assis
tance.
- The protection mechanism will not open if
you try to add fuel from a spare fuel canis
ter. You can get round this simply by adding
the diesel fuel slowly.

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other
