Unfastening of seat belts
Push the release button (3) in the belt buckle (2).
Allow t he retractor to completely rewind t he seat belt by
guiding the latch plate (1).
Operation
The inertia reel stops the belt from unwinding during
sudden vehicle stops or when quickly pulling on the
belt. The locking function of the reel may be checked by
quickly pulling out the belt.
Wa r n i n 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 section, as that could result
in serious injuries 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, including rollovers. The
integrated restraint system includes SRS
(driver airbag, front passenger airbag, front
and rear door mounted side impact airbags,
head protection window curtain airbags for
side windows), ETD (seat belt Emergency
Tensioning Device ), and front seat knee
bolsters. The system is designed to enhance the
protection offered to properly belted occupants
in certain frontal (front airbags) and side (side
impact and window curtain airbags) impacts
which exceed preset deployment thresholds.

Supplemental restraint system (SRS)
Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.
The SRS uses two crash severity levels (thresholds) to
activate either the Emergency Tensioning Device (ETD)
or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.Seat belt fastened
•first threshold exceeded:
ETD activates
•second threshold exceeded:
airbag also activates
Seat belt not fastened
Front seats:
•first threshold exceeded:
airbag activates, but not ETD
Rear outer seats:
•first threshold exceeded:
ETD activates
Driver, front passenger and rear outer seat systems
operate independently of each other.

Te ch n i c a l

cluster displayPractical hints Car care Index Emergency tensioning device (ETD)
The seat belts for the front and outer rear seats are
equipped with emergency tensioning devices. These
tensioning devices are located in each belt’s inertia reel
and become operationally ready with the electronic key
in steering lock position 1 or 2.
The ETDs for the driver and front seat passenger are
designed to activate only when the seat belts are
fastened and during certain frontal impacts exceeding
the first threshold of the SRS and in rear impacts
exceeding a preset severity level. They remove slack
from the belts in such a way that the seat belts fit more
snugly against the body restricting its forward
movement as much as possible.
The rear seat belt ETDs will deploy in the same
circumstances whether or not the seat belts are
fastened.In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear forces, the emergency
tensioning devices will not be activated. The driver and
passengers will then be protected by the fastened seat
belts and inertia reel in the usual manner.
For seat belt and emergency tensioning device safety
guidelines, see page 75.
Note:
The front ETD activates only if the front seat is occupied
and the seat belt is fastened.
Objects heavier than 20 lbs (9 kg) on the front
passenger seat can appear to the SRS to indicate the
presence of an occupant in that seat which causes the
passenger front airbag to deploy and the ETD to activate
in a crash exceeding the appropriate threshold.

Airbags
1Driver airbag
2Front passenger airbagThe most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.
In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds.
Door mounted side impact and head protection window
curtain airbags can provide increased protection to
belted outboard occupants on the impacted side of the
vehicle in side impacts exceeding its preset threshold.
The operational readiness of the airbag system is
verified by the indicator lamp SRS in the instrument
cluster when turning the electronic key in steering lock
to position 1 or 2. If no fault is detected, the lamp will go
out after approximately 4 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 4 seconds or if it comes on thereafter, a
malfunction in the system has been detected.

Front airbags
The driver and passenger front airbags are designed to
activate only in certain frontal impacts exceeding a
preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the 7 indicator lamp
on the center console is not illuminated.
Note:
Objects heavier than 20 lbs (9kg) on the front passenger
seat can appear to the SRS to indicate the presence of an
occupant in that seat which causes the passenger front
airbag to deploy in a crash exceeding the appropriate
threshold.Side impact airbags, window curtain airbags

The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbags on the impacted side of the
vehicle deploy.
The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.
Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.
Note:
Heavy objects on front passenger seat can cause the
front passenger-side impact airbag to deploy in a crash.Window curtain airbags
The head protection window curtain airbags afford
greater protection against injuries to the head and
upper body. They fill up in the area between the A and
C pillars (see arrows) between the side windows and an
occupant’s head.
The window curtain airbags are designed to activate
only in certain side impacts exceeding a preset
threshold. Only the head protection window curtain
airbag on the impacted side of the vehicle deploys.

Important!
Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
and head protection window curtain airbags)
impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.
The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their supplemental protection.
In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents, the airbags will not be activated.
The driver and passengers will then be protected by
the fastened seat belts.
We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.
Wa r n i n g !
Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts, or
side (side impact and head protection window
curtain airbags) impacts which may cause
significant injuries, however, no system available
today can totally eliminate injuries and fatalities.The activation of the SRS temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious to your health, nor
does it indicate a fire in the vehicle. The dust might
cause some temporary breathing difficulty for
people with asthma or other breathing trouble. To
avoid this, you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any breathing
difficulty but cannot get out of the vehicle after the
airbag inflates, then get fresh air by opening a
window or door.

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide
supplemental crash protection for occupants.
Wa r n i n g !
To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear their seat belts.For maximum protection in the event of a collision
always be in normal seated position with your back
against the backrest. Fasten your seat belt and
ensure that it is properly positioned on your body.Since the airbag inflates with considerable speed
and force, a proper seating and hands on steering
wheel position will help to keep you at a safe
distance from the airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:
• Sit properly belted in an upright position with
your back against the backrest.• Adjust the driver’s seat as far as possible
rearward, still permitting proper operation of
vehicle controls. distance from the center of
the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the
steering wheel or dashboard.• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand / arm injury when driver front airbag
inflates.• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.
