Restraint system: introduction
The restraint system reduces the risk of occu-
pants hitting parts of the vehicle interior in the
event of an accident. Furthermore, the
restraint system may also reduce the forces
exerted on the vehicle occupants when an
accident occurs.
The restraint system includes:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer the intended level of protection if all
vehicle occupants:
R are correctly wearing their seat belts.
(Y page 47)
R adjust their seat and head restraint prop-
erly (Y page 107).
The driver is also responsible for ensuring
that the steering wheel has been correctly
positioned. Observe the information relating
to the correct driver's seat position
(Y page 106).
Always ensure the air bag can inflate properly if deployed (Y page 50).
An air bag supplements a correctly fastened
seat belt and is an additional safety device
providing increased protection for vehicle
occupants in appropriate accident situations.
For example, if the protection already provi-
ded by a correctly fastened seat belt will suf-
fice, the air bags are not deployed. Further-
more, only the air bags that would increase
the degree of protection afforded to the vehi- cle occupants in the event of an accident are deployed. Seat belts and air bags generally do
not protect against objects penetrating the
vehicle from the outside.
Information on the restraint system operation can be found under "Triggering of belt ten-
sioners and air bags" (Y page 58).44
Occupant safetySafety

continuously or flash. In addition, there may
be a warning tone.
Regardless of whether the driver's and front- passenger seat belts have already been fas-
tened, the 0076seat belt warning lamp lights
up for six seconds each time the engine is
started. If, after six seconds, the driver or
front-passenger seat belt has not been fas-
tened and the doors are closed, the 0076seat
belt warning lamp lights up. As soon as the
driver's and front-passenger seat belts are
fastened or a front door is opened again, the
0076 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after six seconds or when the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
i For more information on the
0076seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (Y page 327). Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (Y page 58).However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
R Only hold the steering wheel on the out-
side. This allows the air bag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth- 50
Occupant safetySafety

erwise be in the deployment area of the air
bag.
R For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under 12 years of
age and less than 5 ft (1.50 m)in height in
suitable child restraint systems.
R Child restraint systems should be installed
on the rear seats.
R Only secure a child in a rearward-facing
child restraint system to the front-
passenger seat when the front-passenger
front air bag is disabled. If the PASSENGER
AIR BAG OFF indicator lamp is permanently
lit, the front-passenger front air bag is dis-
abled (Y page 45).
R Always observe the instructions and safety
notes on the "Occupant Classification Sys-
tem (OCS)" (Y page 53) and on "Children
in the vehicle" (Y page 61) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may pre-
vent the air bag from functioning cor-
rectly. Before starting your journey and to
avoid risks resulting from the speed of the air bag as it deploys, make sure that:
R there are no people, animals or objects
between the vehicle occupants and an air
bag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors, side
windows, rear side trim or side walls.
R no heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place. G
WARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objectsto it. G
WARNING
Sensors to control the air bags are located in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air bags might therefore not function properly
any more. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work- shop.
Front air bags Driver's air bag
0043inflates in front of the
steering wheel; front-passenger air bag 0044
inflates in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection on the front
seats.

Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R be sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (Y page 53)G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury. When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. G
WARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit- ting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 46) and the notes on correct use of
seat belts (Y page 47).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lbs (18 kg) or until they reach a height
where a lap/shoulder belt fits properly with-
out a booster seat. Special seat belt retractor

Driving safety systems
Overview of driving safety systems
In this section, you will find information about the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 68)
R BAS (Brake Assist System) (Y page 69)
R BAS PLUS (Brake Assist System Plus)
(Y page 69)
R COLLISION PREVENTION ASSIST (distance

R ADAPTIVE BRAKE (Y page 76)
R PRE-SAFE ®
Brake (Y page 76)
R STEER CONTROL (Y page 77)Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt
your driving style to suit the prevailing road
and weather conditions and maintain a safe
distance from the vehicle in front. Drive care-
fully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special atten- tion to the notes on tires, recommended
minimum tire tread depths, etc.
(Y page 406).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
The 0025 ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 328) and
display messages which may be shown in the
instrument cluster (Y page 293).
ABS works from a speed of about 5 mph
(8 km/ h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. 68
