Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual. Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts
R Child restraints
R Lower Anchors and Tethers for CHildren
(LATCH) also known as ISOFIX
Additional protection
potential is provided by:
R Supplemental Restraint System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
- Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
R Preventive occupant safety (PRE-SAFE
®
)
R Air bag system components with
-Front passenger front air bag off
indicator lamp
- Front passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their
protective functions

work in conjunction with
each other. G
Warning!
Modifications to or work improperly
conducted on restraint system components or their wiring, as well as tampering with
interconnected electronic systems, can lead
to
the

restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See “Children in the vehicle”
(Y page 51) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp 6 in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a

few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
6 is not lit while the engine is running. G
Warning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
6
R does not come on at all
R fails to go out after approximately
4 seconds after the engine was started
R comes on after the engine was started or
while driving 36

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.
Side impact air bags G

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
R in certain vehicle rollovers, if the system
determines that air bag deployment can
offer additional protection to that provided
by the seat belt
Window curtain air bags : are not deployed
in impacts which do not exceed the system’s
deployment threshold.
Window curtain air bags : deploy in the area
indicated by the arrows. Occupant Classification System
The Occupant Classification System (OCS)
activates or deactivates the front passenger
front air bag automatically. The respective
status is based on the classified occupant
weight category determined by weight sensor
readings from the front passenger seat. Occupant safety

The system does not deactivate
R
the front passenger side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices (ETDs)
To be
classified correctly, the front passenger
must sit
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 42 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 42 indicator lamp goes out.
In the event of a collision, the air bag control
unit will

not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-month-
old child in a standard child restraint or if the
front passenger seat is classified as being
empty. When the OCS senses that the front
passenger seat occupant is classified as
being
up

to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
42 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the
42 indicator lamp illuminated,
the front passenger front air bag is
deactivated. With the 42
indicator lamp out, the front passenger front
air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 42 indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then go out,
indicating that the front passenger front air
bag is activated.
If the 42 indicator lamp is
illuminated, the front passenger front air bag
is deactivated and will not be deployed. 42

ABS
G
Observe Safety notes, see page 56. G
Warning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake
pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking

power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver X
Keep continuous full pressure on the brake
pedal. G
Warning!
If the ABS malfunctions, other driving safety
systems such

as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance. BAS
G
Observe Safety notes, see page 56.
The Brake Assist System (BAS) operates in
emergency situations.

If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated. G
Warning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the

braking distance may increase. BAS PLUS
The Brake Assist System PLUS (BAS PLUS)
operates in

emergency braking situations and
uses radar sensors to assess the traffic
situation. BAS PLUS assists you in braking at
speeds above approximately 20 mph
(30 km/h).
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar Driving safety systems

R Advanced Parking Guidance ( Y page 327)G
Warning!
BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident. Personal or fatal
injury to you or others may be the result.
i This device

has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
BAS PLUS detects obstacles that are in your
driving path for a sufficient period of time to
permit the system to recognize these
obstacles. If you approach the detected
obstacle quickly, BAS PLUS calculates the
level of brake power boost appropriate for the circumstance to supply when the driver
applies the brakes.
When you step quickly on the brake pedal in
an emergency braking situation, BAS PLUS
automatically regulates the brake power
boost to a level that is suitable for the traffic
situation.
If BAS

PLUS requires a particularly high brake
power boost, PRE-SAFE ®
is activated at the
same time.
X Keep constant pressure on the brake pedal
until the emergency braking situation is
over.
During this process, the ABS prevents the
wheels from locking up.
The brakes will resume normal operation
after
R the brake pedal is released
R no obstacles are detected in your path
R the system no longer senses a risk of a
collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles
such as standing or parked vehicles at road
speeds of up to approximately 40 mph
(70 km/h ).
BAS

PLUS can only assist you when the radar
sensors are switched on and functional. You
can check whether the sensors are active by
switching on DISTRONIC PLUS
(Y page 304) or using the Radar sensors
function ( Y page 216) in the instrument
cluster control system. G

BAS PLUS will only respond with brake
assistance if

it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages 58
