Safety guidelines for the seat belt,
Emergency Tensioning Device and
air bag
i
Air bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag), side impacts (side impact and window
curtain air bags) which exceed preset thresholds
and in certain rollovers (window curtain
air bags). Only during these events will they pro-
vide their supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental pro-
tection.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not be deployed. The driver and passenger will
then be protected to the extent possible by a
properly fastened seat belt. A properly fastened
seat belt is also needed to provide the best pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
that the vehicle will continue to provide supple-
mental crash protection for occupants.
Warning!
G


Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.


Air bags and Emergency Tensioning De-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or ETD
that was activated must be replaced.


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 front seat
backrests, door trim panels,
or door frame trims, and installation of
additional electrical/electronic equip-
ment on or near SRS components and
wiring. Keep area between air bags and
occupants free from objects (e.g. pack-
ages, purses, umbrellas, etc.).


Do not pass belts over sharp edges.
They could tear.


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


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 de-
ployed.


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.

70 Safety and SecurityOccupant safetyThe air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The front passenger air bag will only be
deployed if:


the front passenger seat is occupied


the 75indicator lamp in
the center console is not lit
(page 76)


the impact exceeds a preset deploy-
ment threshold
Knee bag
The knee bag is located on the driver-side
lower instrument panel. It is designed to
operate together with the driver air bag in
certain frontal impacts exceeding a preset
threshold. The knee bag operates best in
conjunction with a properly positioned and
fastened seat belt.Side impact air bags, window curtain
air bags

3Rear side impact air bags
i
The front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of vehicle deceleration as as-
sessed by the air bag control unit.
USA only:
On the front passenger side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 71).
USA only:
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.
!
Canada only:
Do not place objects heavier than 20 lb (9 kg) on
the front passenger seat. This could cause the
front or side impact air bag on the front passen-
ger side to deploy in a crash which exceeds the
system’s deployment threshold.

71 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are deployed:

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front air bags
In addition, the window curtain air bags2
are deployed:


in certain vehicle rollovers
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.Occupant Classification System
(USA only)
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category. Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all di-
rections at all times.
Both driver and the front passenger should
always use the 75 indicator
lamp as an indication of whether or not the
front passenger is properly positioned.i
The system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the Emergency Tensioning De-
vice.
i
If your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to your authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.

TM without special
child seat installed (Canada only)
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 75indicator lamp
located in the center console comes on for
approximately 6 seconds and then goes
out.
If the 75indicator lamp
should not come on or is continuously lit,
the system is not functioning. You must
see an authorized Mercedes-Benz Center
before seating any child on the passenger
seat.
More information can be found in the
“Practical hints” section (page 355).
i
The system does not deactivate the side im-
pact air bag, the window curtain air bag and the
Emergency Tensioning Device.
Warning!
G
The BabySmart
TM air bag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible child
seat on the front passenger seat, the front
passenger front air bag will not deploy only
if the 75indicator lamp re-
mains illuminated.
Please be sure to check the indicator every
time you use the special system child seat.
Should the indicator lamp go out while the
restraint is installed, please check installa-
tion. If the indicator lamp remains out, do
not use the BabySmart
TM restraint to trans-
port children on the front passenger seat un-
til the system has been repaired.

Occupant safety
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.
Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
or to failure.
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.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!
G
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.


Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver’s front air
bag, driver-side knee bag, front
passenger front air bag, side impact
air bags, window curtain air bags for
side windows), ETD (seat belt Emergen-
cy Tensioning Device), and front seat
knee bolsters.


80 Safety and SecurityOccupant safety
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your pas-
sengers 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.
The system is designed to enhance the
protection offered to properly belted oc-
cupants in certain frontal (front air bags,
driver-side knee bag and ETD) and side
(side impact and window curtain air
bags and ETD) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air
bags and ETD).


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The seat belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.


Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, SmartKeys
etc., as these might cause injuries.


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 a time. Do not fasten a seat
belt around a person and another per-
son 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 seat belt. The lap belt
portion should be positioned as low as
possible on the hips to avoid any possi-
ble pressure 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
or toddler restraints or children in boost-
er seats, always follow the child seat
manufacturer’s instructions.


82 Safety and SecurityOccupant safetyAutomatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety (PRE-SAFE
®)Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:


You execute an emergency braking ma-
neuver and the Brake Assist System
(page 92) is activated.


The PRE-SAFE
® system detects a criti-
cal driving dynamics situation.
In such cases, the following systems are
automatically activated:


The front seat belts are pre-tensioned
electrically.


If the vehicle is in a severe skid or is
spinning, the door windows and the
tilt/sliding sunroof close until a small
gap remains.Vehicles with front passenger seat memo-
ry function*:


If the seat is in an unfavorable position,
it will be adjusted to a better position.
If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning!
G
The PRE-SAFE
® system is intended to re-
duce the effects of a crash on properly
seat-belted vehicle occupants. Despite hav-
ing the PRE-SAFE® system in your vehicle,
the possibility of injuries occurring as a re-
sult of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
i
If the closing procedure of the tilt/sliding
sunroof or door window is blocked, the tilt/slid-
ing sunroof or door window will stop and open
slightly.
i
The PRE-SAFE
® system is activated in the
previously described circumstances only at
speeds exceeding 20 mph (30 km/h).
When the critical driving dynamic situation has
passed without an accident occurring, the
pre-tensioning on the seat belts is deactivated.
You can then adjust the seat, the door windows
and the tilt/sliding sunroof to their previous po-
sition.
