The essentials
Towline anchorages
Att ac
h the b
ar or rope to the towline ancho-
rages.
The towline anchorages are located under
the floor panel in the luggage compartment,
next to the vehicle tools ›››
 page 95.
Screw the towline anchorage into the screw
connection ››› Fig. 77 o ››› Fig. 78 and tighten
it with the wheel brace.
Tow rope or tow bar
The tow bar offers increased safety and a
lower risk of damage.
The tow rope is recommended when there is
no tow bar. It must be elastic so that it does
not damage the vehicle.
Notes for the driver of the towing vehicle
● The tow rope must be taut before you drive
off.
● Rel

ease the clutch very carefully when start-
ing the v
ehicle (manual gearbox), or acceler-
ate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow. Do not pull too hard with the towing vehicle
and take c

are to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times.

If the engine will not start, first try starting it
us
in

g the battery of another vehicle
››› page 70. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
When tow-starting a vehicle with a petrol en-
gine, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter.
● Engage 2nd or 3rd gear before moving off.
● Press the clutch and hold the pedal down.
● Switch the ignition on.
● Once both vehicles are moving, release the
clut c

h.
● As soon as the engine has started, press
the clutc
h and move the gear lever to neutral.
How to jump start Jump lea
ds The jump lead must have a sufficient wire
c
r
o

ss section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine. 70

The essentials
Jump leads must comply with standard DIN
72553 (see c ab
l
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic

les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected t
o the on-board network. How to jump start: description

ition the leads in such a way that
they cannot come into contact with any
moving parts in the engine compart-
ment.
Starting Start the engine of the vehicle with the
boosting battery and let it run at idling
speed.
Start the engine of the vehicle with the
flat battery and wait for 2 or 3 minutes
until the engine is running.
Removing the jump leads Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads in reverse order to the details
given above. »

Safety
●
Adjus t
the driver's seat so that there is at
least 25 cm distance between the centre of
the chest and the centre of the steering
wheel ››› Fig. 84. If you are sitting closer than
25 cm, the airbag system cannot protect you
properly.
● If your physical constitution prevents you
from maint
aining the minimum distance of 25
cm, contact a specialised workshop. The
workshop will help you decide if special spe-
cific modifications are necessary.
● When driving, always hold the steering
wheel with both h
ands on the outside of the
ring at the 9 o'clock and 3 o'clock positions.
This reduces the risk of injury when the driver
airbag is triggered.
● Never hold the steering wheel at the 12
o'clock
position, or in any other manner (e.g.
in the centre of the steering wheel). In such
cases, if the airbag is triggered, you may sus-
tain injuries to the arms, hands and head.
● To reduce the risk of injury to the driver
during sud
den braking manoeuvres or an ac-
cident, never drive with the backrest tilted far
back! The airbag system and seat belts can
only provide optimal protection when the
backrest is in an upright position and the
driver is wearing his or her seat belt correct-
ly.
● Adjust the head restraint properly to ach-
ieve optima

Adjusting the front passenger seat
››› page 152. WARNING
● An incorr ect

sitting position of the front
passenger can lead to severe injuries.
● Adjust the front passenger seat so that
there is
at least 25 cm between your chest
and the dash panel. If you are sitting closer
than 25 cm, the airbag system cannot protect
you properly.
● If your physical constitution prevents you
from maint
aining the minimum distance of 25
cm, contact a specialised workshop. The
workshop will help you decide if special spe-
cific modifications are necessary. 76

Safety
●
The slot in the se
at belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging se-
curely.
● Never use seat belt clips, fastening rings or
simil
ar items to alter the position of the belt
webbing.
● Frayed or torn seat belts or damage to the
connections, belt
retractors or parts of the
buckle could cause severe injuries in the
event of an accident. Therefore, you must
check the condition of all seat belts at regular
intervals.
● Seat belts which have been worn in an acci-
dent and hav
e been stretched must be re-
placed by a specialised workshop. Renewal
may be necessary even if there is no apparent
damage. The belt anchorage should also be
checked.
● Do not attempt to repair a damaged seat
belt y
ourself. The seat belts must not be re-
moved or modified in any way.
● The belts must be kept clean, otherwise the
retract
ors may not work properly. Head-on collisions and the laws of

driver who is wearing a seat belt. It is easy to explain how the laws of physics
w
ork
in the c

ase of a head-on collision: when
a vehicle starts moving, a type of energy called “kinetic energy” is created both in the
pas

sengers and inside the vehicle.
The amount of “kinetic energy” depends on
the speed of the vehicle and on the weight of
the vehicle and of its passengers. The higher
they are, the more energy there is to be “ab-
sorbed” in the event of an accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Given that the passengers of the vehicle in
our example do not have their seat belts fas-
tened, in the event of a collision the entire
amount of the passengers' kinetic energy will
be only absorbed by the mentioned impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on bod-
ies in a collision can easily exceed one tonne
(1000 kg). At greater speed these forces are
even higher.
Vehicle occupants not wearing seat belts are
not “attached” to the vehicle. In a head-on
collision, they will move forward at the same
speed their vehicle was travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions.
Even at low speeds the forces acting on the
body in a collision are so great that it is not
