Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag
Warning!G

Damaged seat belts or seat belt that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.

Air bags and pyrotechnic emergency
tensioning devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced. PRE-SAFE
® has electrically
operated reversible pre-tensioners in
addition to the pyrotechnic ETDs.

Do not pass seat belt over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the seat
belts.

Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when the window curtain air bag is
deployed.

Air bag system components will be hot
after an air bag has inflated. Do not
touch.

Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.

For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from any authorized Mercedes-Benz
Center.

Occupant safety
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate for
6 seconds to remind you and your passen-
gers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’ s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with front doors closed,

the seat belt telltale< remains illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt is not
fastened.

and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
intensity for a maximum of 60 seconds
or until the driver’s and the front pas-
senger’s seat belt are fastened.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.
For more information, see “Practical hints”
(
page 605).

Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the seat belt is positioned across
your abdomen, it could cause serious in-
juries in a crash.

Never use a seat belt for more than one
person at time. Do not fasten a seat belt
around a person and another person or
other objects.

Seat belts should not be worn twisted.
In a crash, you wouldn’t have the full
width of the seat belt to distribute im-
pact forces. The twisted seat belt
against your body could cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.

Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.

When using a seat belt to secure infant
restraint, toddler restraint, or booster
seat, always follow the child seat manu-
facturer’s instructions.

Exterior lamp switch
The exterior lamp switch is located on the
dashboard to the left of the steering wheel.iIf you drive in countries where vehicles drive
on the other side of the road than the country in
which the vehicle is registered, you must have
the headlamps modified for symmetrical low
beams. Relevant information can be obtained at
any authorized Mercedes-Benz Center.
iThe active Bi-Xenon headlamps monitor
your steering angle and driving speed, then auto-
matically shift their beams to either side to bet-
ter follow the curvature of the road ahead,
increasing usable illumination over conventional
headlamps.

Driving systems

Front area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approximately two sec-
onds. Once the second red segment
lights up, you will hear a continuous
warning tone. You have reached the
minimum distance.

Rear area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approximately two sec-
onds. Once the second red segment
lights up, you will hear a continuous
warning tone. You have reached the
minimum distance.Collision warning
Park Assist can detect obstacles from a
considerable distance. If you drive in re-
verse towards an obstacle, you will hear a
warning tone. You must then brake in or-
der to avoid a collision. The warning tone
for a collision will not sound when the vehi-
cle is at a standstill very close to the obsta-
cle. In this case, you will hear a
corresponding tone for the warning indica-
tor in the rear area.Switching Park Assist system on/off
The Park Assist system can be switched off
manually.
The Park Assist button with the indicator
lamp is located on the control panel on the
right-hand side of the instrument cluster.
