mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.
Visit a qualified specialist workshop.

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and the front passenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and the front passenger
have fastened their seat belts, the
7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrumentc luster, seat
belt" (Y page 231).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the display
indicates a fastened seat belt. If a seat belt is
not fastened or if a seat is not occupied, the
ý symbol is displayed.
The rear-compartment seat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again. Example: the occupant on the left rear seat is
secured46

indicator immediately:

Belt tensioners, belt force limiters G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The fron tseat belts are equipped with belt
tensioners and belt force limiters. The outer
seat belts in the rear are equipped with seat
belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak forc eexerted by the seat
belt on the vehicle occupant.
The front belt force limiters are synchronised
with the front airbags, which take on a part of
the deceleratio nforce. Thus, the force exer- ted on the occupant is distributed over a
greater area.
The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact if the vehicle
is subjected to high lateral acceleration/
deceleration
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up. Children in the vehicle

of an accident, sudden braking or abrupt
change in direction, they could injure vehicle
occupants or cause damage to the vehicle.
When you are not using the ICS padded play
table and the side head restraints, store these
in a suitable place, such as the boot.
On vehicles with a TIREFIT kit, for example,
you can store the side head restraints in the
stowage compartment under the luggage

Adaptive brake lamps
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BA SPLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
lightu p continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/ h.You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 99).
i Adaptive brake lamps are only available in
certain countries. ESP

Important safety notes G
WARNING
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weathe rconditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the electric parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with the front/
rear axle raised.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system. If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster.
i Observe the "Important safety notes" sec-
tion (Y page 62).
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Traction control Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active if you deacti-
vate ESP ®
.
i Observe the "Important safety notes" sec-
tion (Y page 62).
Deactivating/activating ESP ® G
WARNING
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and åwarning
lamp are lit continuously, ESP ®
is not availa-
ble due to a malfunction.
There is an increased risk of your vehicle skid-
ding in certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions. 66
