installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check with your local
government’s disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.
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 a crash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do no change or remove any component or
part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, passenger front air bag cover,
outboard sides of the seat backrests, door
trim panels, or door frame trims.
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
R Air bag system components will be hot after
an air bag has inflated. Do not touch them.
R 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. R
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.
R For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS.
Also refer them to the applicable section in
the Operator’s Manual.
Front air bags G
Observe Safety notes, see page 33. Driver’s front air bag
: and passenger front
air bag ; are designed to provide increased
protection for the driver and passenger
against the risk of injuries to the head and
thorax. Occupant safety

Children in the vehicle
Safety notes If an infant or child is traveling with you in the
vehicle:
X
Secure the child using an infant or child
restraint
appropriate to the age and size of
the child.
X Make sure the infant or child is properly
secured at all times while the vehicle is in
motion. G
Warning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the

vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts. G
Warning!
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place. Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R
strong braking maneuvers
R sudden changes of direction
R an accident
Infant and child restraint systems G
Observe Safety notes, see page 45.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap/shoulder belt has a
special seat belt retractor for secure
fastening of child restraints.
To fasten a child restraint, follow the child
restraint manufacturer’s instructions for
mounting.
To activate the special seat belt retractor:
X Pull the shoulder belt out completely and
let it retract.
During seat belt retraction, a ratcheting
sound can be heard to indicate that the
special seat belt retractor is activated.
The seat belt is now locked.
X Push down on child restraint to take up any
slack.
To deactivate the special seat belt retractor:
X Release the seat belt buckle and let the
seat belt retract completely.
The

seat belt can then again be used in the
usual manner. G
Warning!
Never release the seat belt buckle while the
vehicle
is in motion, since the special seat belt
retractor will be deactivated.
The use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces. Occupant safety

multifunction display.
:
Program mode indicator
You should only change the program mode
when the automatic transmission is in park
position P.
Automatic program mode S will not be stored.
When the engine is turned off with the
automatic program mode S selected, the
automatic transmission will go to the
automatic program mode C when the engine
is restarted.
X Press the program mode selector switch
repeatedly until the letter of the desired
program mode appears in the multifunction

Selecting program mode C means:
R The vehicle starts out more gentle, both
forward and reverse, except when driving
off with full throttle.
R Traction and driving stability are improved
on icy roads.
R Upshifts occur earlier even when you give
more gas. The engine then operates at
lower revolutions and the wheels are less
likely to spin.
Selecting program mode S means that
upshifts occur later. One-touch gearshifting
With the automatic transmission in drive
position D and driving in automatic program mode
C or S, you can limit or extend the gear
range using the gear selector lever or the
steering wheel gearshift control.

The manual shift program is available on
vehicles with AMG Sport Package and on
SLK 55 AMG only.
Manual program mode M differs with regard
to spontaneity, response time, and shifting
smoothness from automatic program mode
S.
In manual program mode M, system-
controlled automatic gearshifting is switched
off. You need to change the gears by manually
upshifting or downshifting using the gear
selector lever or the steering wheel gearshift
control. Program mode selector switch on vehicles with
