Introduction RS consistso
f:
R The 0012 RS warning lamp
R Air bags
R The air bag control unit with crash sensors
R Emergency Tensioning Device for the front
seat belts and the outer seat belts in the

RS reduces the risk of occupants coming into
contact with the vehicle's interior in the event
of an accident. It can also reduce the effect
of the forces to which occupants are
subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident with ahigh rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at aq ualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 0012 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. The SRS components are in operational
readiness when the
0012SRS indicator lamp
goes out while the engine is running.
There is amalfunction if:
R the 0012 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0012SRS
warning lamp does not go out after afew
seconds
R the engine is running and the 0012SRS
warning lamp lights up again.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Ben zCenter.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on aone-time-only basis. An air bag or ETD
that has deployed must be replaced. PRE-
SAFE ®
has electrically operated reversible
belt tensionersina ddition to the
pyrotechnic ETDs.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In acrash they may
not be able to provide adequate protection. Occupant safety

Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To makeaf ull brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
ap ulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and

while driving. BAS (Brake Assist System)
i Observe the "Important safety notes"
section (Y page 66). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergenc ybraking situation is
increased. There is arisk of an accident.
In an emergenc ybraking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergenc ybraking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System
PLUS)
General information i
Observe the "Important safety notes"
section (Y page 66).
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
For BAS PLUS to assist you when driving, the
radar sensor system must be:
R activated (Y page 232)
R operational
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
4m ph (7 km/h).
At speeds of up to approximately 40 mph
(70 km/h) ,BAS PLUS can also react to
stationary objects. Examples of stationary
object sare stopped or parked vehicles.
Important safety notes G
WARNING
BAS PLUS cannot alwaysc learly identify
object sand complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is ar isk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossin gtraffic

Z

As
aresult, BAS PLUS may not intervene in all
critical situations. There is arisk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensor soranythin gelse
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R an arrow vehicle travelin ginfront, e.g. a

Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensor schecked at aqualified
specialist workshop. This also applies to
collisions at low speeds where ther eisno
visible damage to the fron tofthe vehicle.
Braking assistance To prevent
acollision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision
When driving at aspeed under 20 mph
(30 km/h):ify ou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at aspeed greater than
20 mph (30 km/h):ify ou depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure to avalue adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger protection measures (PRE-SAFE
