R Each occupant should wea rthei rseatb elt
at al ltimes ,because sea tbelts hel preduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front ai rbag,k nee bags, front-
passenger front ai rbag,sidei mpact air
bags, hea dairbags) ,Emergency Tension-
ing Device s(ETDs) and sea tbeltf orce lim-
iters .The system is designe dtoenhance
the protection offered to properl ybelted
occupants in certai nfrontal (front ai rbags,
knee bags and ETDs) and sid e(side impact

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.
