WARNING
Children 12 years old and under must be
seated and properly secured in an appropri-
ately sized infant restraint, child restrain tsys-
tem, or booste rseat recommended for the
siz ea nd weigh tofthechild. Fo radditional
information ,see th e"Children in th evehicle"
section.
Ac hild's ris kofserious or fatal injurie sissig-
nificantl yincreased if th echild restraints are
no tproperly secured in th evehicl eand/o rthe
child is no tproperly secured in th echild
restraint. Example: Coupe
X Adjus tthe seat and mov ethe backrest to
an almost vertical position(Y page 85).
X Pull th eseat belt smoothly from belt sash
guide 0043.
X Without twisting it ,guide th eshoulder sec-
tion of th eseat belt across th emiddle of
your shoulder and th elap section across
your hips. X
Engage belt tongue 0044in buckle 0087.
X If necessary, pull upward sontheshoulder
section of th eseat belt to tighten th ebelt
across your body.
The seat belt on th efront-pa ssenger side is
equipped wit haspecial seat belt retracto rto
secure child restraint systems properly on the
front-passenger seat .For further information
on special seat belt retractors, see

Releasing seat belts X
Press release button 0085(Ypage 49 )and
guide belt tongue 0044(Ypage 49 )back
towards belt sash guide 0043(Ypage 49).
! Mak
esure that th eseat belt is fully rolled
up. Otherwise, th eseat belt or belt tongue
will be trapped in th edoor or in th eseat
mechanism .This could damag ethe door,

Bel twarning for th edriver and front
passenger Regardles
sofwhether th edriver' sand front-
passenger seat belt shave already been fas-
tened, the 0076seat belt warning lamp lights
up for six seconds eac htimet he engin eis
started. It then goes out once th edriver and
th ef ront passenger have fastene dtheir seat
belts.
If th edriver' sseat belt is no tfastene dwhen
th ee ngineiss tarted, an additional warning
tone will sound. The warning tone switches
off after approximately six seconds or once
th ed river' sseat belt is fastened. Occupant safety
49Safety Z

If after six seconds the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R the 0076 seat belt warning lamp remains lit
as long as either the driver's or front-pas-
senger's seat belt is not fastened
R and if the vehicle speed exceeds 15 mph
(25 km/h )once, the 0076seat belt warning
lamp lights up. Additionally, awarning tone
sounds with increasing intensity for amax-
imum of 60 seconds or until the driver's and
front passenger's seat belts are fastened.
If the driver or front-passenger seat belt is
unfastened whilet he vehicle is in motion, the
0076 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 0076seat belt
warning lamp stops flashing but remains lit.
After the vehicle comes to astandstill ,the
warning tone is reactivated and the 0076seat
belt warning lamp flashes again if the vehicle
speed exceeds 15 mph (25 km/h).
The 0076 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and adoor is open.

Emergency Tensioning Devices, seat
beltf orce limiters The seat belts are equippedw
ith ETDs and
seat belt force limiters.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwisel eadtot he triggering of the Emer-
gency Tensioning Device in the event of an accident, which willt
hen need to be
replaced.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat posi-
tions or incorrectly fastened seat belts.
The ETDs do not pullv ehicle occupants back
towards the backrest.
Seat belt force limiters, when activated, are
employed to help reduce the peak force
exerted by the seat belts on occupants during ac rash.
The seat belt force limiters are synchronized
with the front air bags,w hich take onapart of
the deceleration force. Thus, the force
exerted on the occupant is distributed over a
greater area.
When the ignition is switched on, the ETDs
cannot be triggered unless:
R the restraint systems are operational; see
"SRS warning lamp"( Ypage 37)
R the belt tongue is engage dinthe buckle on
each of the three-point seat belts
R the front-passenger seat is occupie dand
the belt tongue is engage dinthe buckle on
the front-passenger side
The ETDs are triggered depending on the type
and severity of an accident:
R in the event of ahead-on or rear-end colli-
sion, if the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R in the event of aside impact, if the vehicle
is subjected to high latera lacceleration/
deceleration
R Coupe: in certain situations if the vehicle
rolls over, and the system determines that
it can provide additional protection
R Roadster: if the vehicle rolls over
If the Emergency Tensioning Devices (ETDs)
are triggered, you willh earabang, and asmall
amount of smoke may also be released. Only
in rare cases willt he bang affect yourh earing.
The smoke that is released generally does not 50

You can select between the following states
of ESP ®
:
R ESP ®

R SPORT handling mode is activated.
R ESP ®

WARNING
When SPORT handling mode is activated,
there is agreater risk of skidding and acci-
dents.
Only activate SPORT handling mode in the sit- uations described in the following. G
WARNING
If you deactivate ESP ®
,E SP ®
no longer sta-
bilizes the vehicle. There is an increase drisk
of skidding and an accident. Only deactivate ESP
®
in the situations descri-
bed in the following.
In the following situations, it may be better to activate SPORT handling mode or deactivate
ESP ®
:
R when using snow chains
R in deep snow
R on sand or gravel
R when driving on designated road swhen the
vehicle's own oversteering and understeer-
ing characteristics are desired
Driving in SPORT handling mode or without
ESP ®
requires an extremely qualified and
experienced driver.
i Activate ESP ®
as soon as the situations
described above no longer apply.E SP®

Characteristics of activated SPORT han-
dling mode
SPORT handling mode raises the intervention threshold for stabilizing the vehicle. This
allows for asportier driving style on desig-
nated race circuits and may in certain situa-
tions improve the traction in comparison with
ESP ®
.
If SPORT handling mode is activated and one or more wheels start to spin, the 0089warn-
ing lamp in the instrument cluster flashes.
ESP ®
only stabilizes the vehicle to alimited
degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is only restricted to alimited
degree, and the drive wheels are able to
spin. The spinning wheels produce acut-
ting effect for better traction. Characteristics when ESP
®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 0089warning lamp in the
instrument cluster does not flash. In such sit-
uations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in acutting action for
better traction.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 54).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapty our driving style
to the different handling characteristics. Have the brake system checked at aqualified spe-
cialist workshop.

warning lamps (Y page 192) as well as dis-
play messages (Y page 166). ADAPTIVE BRAKE
