The essentials
the wheel condition and hub mounting surfa-
c e
s.
These surfaces must be clean before fit-
ting the wheel.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm.
After changing a wheel, have the tightening
torque checked immediately with a torque
wrench that is working perfectly.
Before checking tightening torque, have any
rusty wheel bolts that are difficult to screw re-
placed and clean the wheel hub threads.
Never apply grease or oil to wheel bolts or to
the wheel hub threads. Even if the bolts have
been tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not properly tightened,
they c ou

ld come loose while driving and
cause an accident, serious injury and loss of
vehicle control.
● Use only wheel bolts which correspond to
the rim in question.
● Nev

er use different wheel bolts.
● Wheel bolts and threads should be clean,
free of oi
l and grease, and it should be possi-
ble to screw them easily.
● To loosen and tighten wheel bolts, only use
the wheel wrenc
h that came with the car from
the factory. ●
Loo sen the wheel

bolts only about one turn
before raising the vehicle with the jack.
● Never apply grease or oil to wheel bolts or
to the wheel hub thr
eads. Even if the bolts
have been tightened to the prescribed tor-
que, they could come loose while driving.
● Never loosen the screwed joints of wheel
rims with bo
lted ring trims.
● If wheel bolts are tightened below the pre-
scribed t
orque, the bolts and rims could come
loose while driving. If tightening torque is too
high, the wheel bolts or threads can be dam-
aged. CAUTION
When removing/fitting the wheel, the rim
ma y

hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of ro-
t
ation A directional tread pattern can be identified
b
y
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 drivin

g 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.
Subsequent work ●
Alloy wheels: rep
l
ace the wheel bolt caps.
● Plate wheels: repl
ace the wheel hubcap.
● Return all tools to their proper storing loca-
tion.
● If the replaced wheel does not fit in the
spar
e wheel housing, store it safely in the
luggage compartment ›››
 page 158.
● Check the tyre pressure of the newly moun-
ted tyr
e as soon as possible.
● In vehicles fitted with a tyre pressure indi-
cator
, adjust the pressure and store it in
memory ›››
 page 287.
● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench (it should be 120 Nm). Mean-
while, drive carefully.
● Have the flat tyre replaced as quickly as
pos s

ible. 69

Safety
The protective function of seat belts Fig. 98
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. These also help pre-
vent uncontrolled movements that may result
in serious injury and reduce the risk of being
thrown out of the vehicle.
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, rollovers 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. 82

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
ph

orward violently. Fig. 100
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
the speed and the greater the weight, the
more energy 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 (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Because the vehicle occupants in our exam-
ple are not restrained by seat belts, in the
event of crashing against a wall, all of the oc-
cupants' kinetic energy will be absorbed
solely by said 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. »

WARNING
The risk of accidents is high when tow-start-
ing, f or e
xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.
● Switch on the hazard warning lights of both
vehicl
es. However, observe any regulations
to the contrary.
● The tow rope must not be twisted. Other-
wise the fr
ont tow line anchorage could be
pulled off the vehicle. Indications for tow-starting
Vehicle's should not generally be tow-star-
t
ed.
The jump s

tart should be used instead
›››  page 71. For technical reasons, towing the following
vehicl

es 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 battery is flat, it is possible that the
engine contr
ol 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
clutc
h.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. 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 ther

e 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. 101

Changing bulbs requires a certain degree of
practical skill.
If you choose to change the engine compart-
ment lamps yourself, remember that it is a
dangerous area ››› in Safety notes for work
in the en gine c
omp

artment on page 273.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder. Depending on how equipped the vehicle is,
there are diff

erent sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the vehicle and the bulbs cannot
be replaced. In case of headlight failure, go
to an authorised workshop to have it re-
placed. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. 106
