These surfaces must be clean before fit-
ting the wheel.
Tyres with compulsory direction of ro-
tation A directional tread pattern can be identified
by
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.

● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench (it should be 140 Nm). Mean-
while, drive carefully.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use Snow chains should only be used on the

s.
Check that they are correctly seated after
driving for a few yards; correct the position if
necessary, in accordance with the manufac-
turer's fitting instructions. Keep your speed
below 50 km/h (30 mph). If there is a danger of being trapped despite
havin
g mounted the chains, it is best to disa-
ble the driving wheels (ASR) in the ESC
››› page 191, Switching on/off the ESC
and ASR.
Snow chains will improve braking ability as
well as traction in winter conditions.
For technical reasons snow chains may only
be used with the following wheel rim/tyre
combination.
215/60 R16Chains with links of maximum 15 mm
215/55 R17Chains with links of maximum 15 mm

Remove the chains when roads are free of
snow. Driving characteristics worsen, and the
wheels become damaged quickly and may
even be rendered unusable. 67
Safety
The protective function of seat belts Fig. 90
Drivers with properly worn seat belts
w i
l
l not be thrown forward in the event of sud-
den braking. Properly worn seat belts hold the occupants
in the pr
oper po
s
ition. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas-
sive safety features (such as the airbag sys-
tem) are designed to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing around the corner". Ensure that your passengers wear their seat
belts as
well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury
and improving the chances of survival when
involved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, overturns or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!
Important safety instructions for the
use of se
at belts –
Always wear the seat belt as described in
thi s
section.
– En
sure that the seat belts can be fastened
at all
times and are not damaged. WARNING
● If se at
belts are worn incorrectly or not at
all, the risk of severe injuries increases. The
optimal protection from seat belts can be
achieved only if you use them properly.
● Fasten your seat belt before every trip -
even when drivin
g in town. Other vehicle oc-
cupants must also wear the seat belts at all
times, otherwise they run the risk of being in-
jured.
● The seat belt cannot offer its full protection
if the seat
belt is not positioned correctly.
● Never allow two passengers (even children)
to shar
e the same seat belt.
● Always keep both feet in the footwell in
front of
your seat as long as the vehicle is in
motion.
● Never unbuckle a seat belt while the vehi-
cle i
s in motion. Risk of fatal injury.
● The seat belt must never be twisted while it
is bein
g worn.
● The seat belt should never lie on hard or
fragil
e objects (such as glasses or pens, etc.)
because this can cause injuries.
● Do not allow the seat belt to be damaged or
jammed, or to rub on an
y sharp edges.
● Never wear the seat belt under the arm or
in any other inc
orrect position.
● Bulky and unfastened clothing (such as an
over
coat over a sweater) impairs the proper
fit and function of the seat belts, reducing
their capacity to protect. 80
Seat belts
●
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

orward violently. Fig. 92
The unbelted passenger in the rear

i
s thrown forward violently, hitting the
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 »

The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
jects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tyre mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F). ●
In the ev ent
of
cuts or perforations in the
tyre greater than 4 mm.
● If you have been driving with very low pres-
sure or a c
ompletely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
ger ou
s, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury:
● Stop the vehicle safely as soon as possible.
Park it
at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid.
● Al
l passengers and particularly children
must
keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Use the tyre mobility system only if you are
famili
ar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary
emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tyre mo-
bility
set as soon as possible. » 95

For technical reasons, towing the following
vehicles is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cause in
vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated. ●
If the batt
ery is flat, it is possible that the
engine control units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Once both
vehicles are moving, release the

h.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. CAUTION
When tow-starting, unburnt fuel could enter
the cat a
lytic converter and damage it. Note
The vehicle can only be tow-started if the
electr onic
parking brake and, if appropriate,
the electronic lock of the steering column are
deactivated. If the vehicle has no power sup-
ply or there is an electric system fault, the
engine must be tow-started to deactivate the
electronic parking brake and the electronic
lock of the steering column. Indications for towing
Tow rope or tow bar
It i
s
safer for the vehicle to be towed using a
tow bar, avoiding damage to the vehicle. A
tow rope should only be used if a tow bar is
not available.
A tow rope should be slightly elastic to avoid
damage to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
Only attach the tow rope or the tow bar to the
towing eyes provided or a towing bracket.
If the vehicle is factory-equipped with a tow-
ing bracket, it is only allowed to tow with a
tow bar if this has been specially designed to
be installed with a tow hitch ›››
page 276.
When the vehicle needs to be towed:
Check whether the vehicle may be towed

is not allowed .
● Switch the ignition on.
● Put the gearbox lever in neutral or the se-
lect or l
ever in the N ›››

CAUTION
● The to w

and firmly tightened. Otherwise, it could be
released while towing and tow-starting.
● If the vehicle is factory-equipped with a
tow
ing bracket, it is only allowed to tow with
a tow bar if this has been specially designed
to be installed with a tow hitch. If an unsuita-
ble tow bar is used, both the tow hitch and
the vehicle may be damaged. Instead, a tow
rope should be used. Driving tips for towing
Towing requires some expertise and experi-
enc
e, e
s
pecially when using a tow rope. Both
drivers should be familiar with the difficulties
involved in towing. For this reason, inexper-
ienced drivers should abstain from towing.
During towing, it should be ensured that no
impermissible tractive forces or shocks are
generated. When towing on an unpaved
road, there is always a risk of overloading
and damaging the anchorage points.
During towing, the towing vehicle can signal
the change of direction even with the hazard
warning lights turned on. To do so, at the
same time, the turn signal lever must be op-
erated with ignition switched on. Meanwhile,
the hazard warning lights will go off. When
the turn signal lever is returned to the rest position, the hazard warning lights will be
automatic
ally reactivated.
Notes for the driver of the towed vehicle ● Leave the ignition on, so that the steering
is not
blocked, and the electronic parking
brake may be deactivated and the turn sig-
nals and wash/wipe operated.
● More strength is required at the steering
wheel as
the power steering does not oper-
ate when the engine is switched off.
● You should depress the brake much harder
as the br
ake servo does not operate. Avoid
hitting the towing vehicle.
● Bear in mind the information and instruc-
tions in the m
anual of the vehicle to be tow-
ed.
Notes for the driver of the towing vehicle
● Accelerate with particular care and caution.
Avoid sh
arp manoeuvres.
● Brake earlier than usual and smoothly.
● Bear in mind the information and instruc-
tions in the m
anual of the towed vehicle. Fuses and bulbs
F u
se
s
Introduction In general, a fuse can be assigned to various
electric
al
components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s
electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr
ent circuit without fuses can
cause a fire and serious injury. 102
