Front air bags
G
Observe Safety notes, see page 37. Driver’s front air bag
: and front passenger
front air bag ; are designed to provide
increased protection for the driver and front
passenger against the risk of injuries to the
head and thorax.
Driver and front passenger front air bag and
driver’s side knee bag are deployed
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the respective seat
belt is in use
R independently of the side impact air bags
and/or the window curtain air bags
The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags to have different rates of inflation.
The rate of inflation is based on the vehicle
deceleration rate as assessed by the air bag
control unit.
The front passenger front air bag deployment
is additionally influenced by the passenger’s
weight category as identified by the Occupant
Classification System (OCS) ( Y page 41).
The lighter the front passenger-side
occupant, the higher the vehicle deceleration
rate required for second stage inflation of the
front passenger front air bag.
The air bags will not deploy in impacts which
do not exceed the system’s preset deployment thresholds. You will then be
protected by the fastened seat belts.
The front air bags will not deploy in the event
of a rollover unless the vehicle’s rate of
longitudinal deceleration or acceleration
exceeds the preset deployment threshold for
the front air bags.
The front passenger front air bag will only be
deployed if
R
the system, based on OCS weight sensor
readings, detects that the front passenger
seat is occupied
R the 42 indicator lamp in the
center console is not lit (Y page 41)
R the impact exceeds a preset deployment
threshold
Knee bag
Knee bag = is designed to provide increased
protection for the driver against the risk of
injuries to the knees, thighs and lower legs.
Knee bag = is located on the driver side
lower instrument panel. It is designed to
operate together with the driver front air bag
in certain frontal impacts if the system
determines that air bag deployment can offer
additional protection to that provided by the
seat belt. Knee bag = operates best in
conjunction with a properly positioned and
fastened seat belt.

Front side impact air bags
: and rear side
impact air bags ; are designed to provide
increased protection for the thorax but not
the head, neck and arms.
The side impact air bags are deployed
R on the impacted side of the vehicle
R in instances with a high rate of lateral
vehicle deceleration or acceleration
R regardless of whether the seat belts on the
impacted side of the vehicle are in use
R independently of the front air bags
R independently of the ETDs
The front passenger side impact air bag will
not deploy if the OCS senses that the front
passenger seat is empty and the front
passenger seat belt is not fastened. With the
front passenger seat empty and the seat belt
fastened, the front passenger side impact air
bag will deploy independently of the empty
seat. Whether a seat belt is recognized as
fastened depends on whether or not the latch
plate is properly inserted into the buckle.
The side impact air bags are not deployed in
side impacts which do not exceed the
system’s deployment threshold.
The side impact air bags will not deploy in the
event of a rollover unless the vehicle’s rate of
lateral deceleration or acceleration exceeds
the preset deployment threshold for the side
impact air bags. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability. Window curtain air bags G
Observe Safety notes, see page 37. Window curtain air bags
: are designed to
provide increased protection for the head but
not the chest or arms.
Window curtain air bags : are deployed
R on the impacted side of the vehicle
R in instances with a high rate of lateral
vehicle deceleration or acceleration
R independently of the front air bags
R regardless of whether the front passenger
seat is occupied
R regardless of whether the seat belt on the
impacted side of the vehicle is in use

Warning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be
placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer’s instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child. Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R
Your vehicle is equipped with air bag
technology designed
to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 42
indicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 42
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
42 indicator lamp while
driving to make sure the 42
indicator lamp is illuminated. If the
42 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.

seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.
G
Warning!
Never let more people ride in the vehicle than
there are seat belts available. Make 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. G
Warning!
Damaged seat belts or seat belts that have
been subjected
to stress in an accident must
be replaced. Also, the seat belt anchoring
points must be checked.
Only use seat belts which have been approved
by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate when
necessary.
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.
Proper use of seat belts G
Warning!
USE SEAT BELTS PROPERLY
R Seat belts can only protect 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.
R 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 front air bag, driver side knee
bag, front passenger front air bag, side
impact
air
bags, window curtain air bags for
side windows), Emergency Tensioning
Devices (ETDs), seat belt force limiters, and
front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver’s side knee bag, and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
R Never wear the shoulder belt under your
arm, against your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm.
R Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
a crash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt 46

Enhanced seat belt reminder system When the engine is started, the seat belt
telltale
7 will always illuminate for
6 seconds
to remind you and your passengers
to fasten your seat belts.
If the driver’s seat belt is not fastened when
the engine is started, an additional warning
chime will sound. The warning chime goes out
after approximately 6 seconds or once 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
both doors closed,
R the seat belt telltale 7 remains
illuminated for as long as either the driver’s
or front passenger’s seat belt is not
fastened.
R and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a maximum of 60 seconds or until the
driver’s
and
front passenger’s seat belt are
fastened.
If you and/or your passenger release the
seat belt during driving, the seat belt
telltale 7 starts flashing and the
warning chime sounds as described before.
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 7 stops flashing but
continues to be illuminated.
After a vehicle standstill, the warning chime
is reactivated and the seat belt telltale
7 is flashing again if the vehicle speed
once exceeds 15 mph (25 km/h).
The seat belt telltale 7 will only go out if
both the driver’s and the front passenger’s
seat belt (with the front passenger seat
occupied) are fastened, or the vehicle is
standing still and a door is opened.
For more information, see “Practical hints”
(Y page 454).
Emergency Tensioning Device (ETD),

Brake
The PRE-SAFE ®
Brake is available in vehicles
equipped with DISTRONIC PLUS. The PRE-
SAFE ®
Brake
can assist you in minimizing the
risk of a rear-end collision with a vehicle in
front of you. The PRE-SAFE ®
Brake may also
reduce the severity of an accident. At speeds above approximately 20 mph (30 km/h) it will
issue a warning when your vehicle is
approaching the preceding vehicle very
quickly. An intermittent acoustic warning

·
in the instrument cluster comes on.
When the driver and front passenger have
fastened their seat belts, the PRE-SAFE ®
Brake can also
R brake the vehicle within a speed range of
up to 112 mph (180 km/h ) automatically
R activate preventative occupant safety
measures (PRE-SAFE ®
) ( Y

Warning!
An intermittent warning sounds and the
distance warning
lamp · in the instrument
cluster is illuminated if the PRE-SAFE ®
Brake
calculates that the distance to the vehicle
ahead and your vehicle’s current speed
indicate that the PRE-SAFE ®
Brake will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle driving in front of you. The warning
sound is intended as a final caution that you
have not interceded with your own braking
inputs to avoid a potentially dangerous
situation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially
dangerous emergency braking which will not
always result in an impact being avoided.
Tailgating increases the risk of an accident. G
Warning!
The PRE-SAFE ®
Brake is a convenience
system designed to assist the driver during
vehicle operation. The responsibility for the
vehicle speed
