Never modify an air bag cover or affix objects
to 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
anymore. 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.
Alway sh ave work on the doors or door pan-
eling carried out at aq ualifie ds pecialist work-
shop.
Front air bags
! Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied .Int he
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag C deploys in front of the steer-
ing wheel .F ront-passenger front air bag D
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
( Y
page 38). The front-passenger front air bag wil lo nly
deplo yi f: R
the system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied ( Y
page 44). The
PASSENGER AIR BAG ON indicator lamp is lit
( Y
page 45) R
the restraint system control unit predicts a
high accident severity
Kne eb ags
Driver's knee bag C deploys under the steering
column and front-passenger knee bag D under
the glove box. The driver's and front-passenger
knee bags are triggered together with the front
air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lowe rl eg pro-
tection.
Side impact air bags
G WARNING
Unsuitabl es eat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. In addition, the operatio no f
the occupant classification system (OCS)
could be adversel ya ffected. This poses an
increased risk of injury or even fatal injury.
You shoul do nly use seat covers that have
been approve df or the respective seat by
Mercedes-Benz.Occupant safety 43
Safety Z

only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as ar esult.
If the control unit of the restraint system detects
as ide impact or av ehicle rollover, the relevant
components of the restraint system are activa-
ted separately depending on the anticipated
type of accident. R
Side impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the
driver's seat
The side impact air bag on the front-
passenger side deploys under the following
conditions: -
the OCS system detect st hat the front-
passenger seat is occupied or -
the belt tongue is engaged in the belt
buckle of the front-passenger seat R
Head bag on the side of impact, independ-
ently of the use of the seat belt and inde-
pendently of whether the front-passenger
seat is occupied R
Emergency Tensionin gD evices, if the system
determines that deployment can offer addi-
tional protection in this situation R
Head bags on the driver's and front-
passenger side in certain situations when the
vehicle rolls over, if the system determines
that deployment can offer additional protec-
tion to that provided by the seat belt
i Not all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident: R
Frontal collision R
Side impact R
Rollover NECK-PRO head restraints
Important safety notes
G WARNING
The function of the head restraint may be
impaired if you: R
attach object ss uch as coat hangers to the
head restraints, for example R
use head restraint covers
If you do so, the head restraint sc annot fulfill
their intended protective function in the event
of an accident .Ina ddition, object sa ttached
to the head restraint sc ould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any object stot he head
restraint sa nd do not use head restraint cov-
ers.
Method of operation NECK-PRO head restraint sr educe the likelihood
of head and chest injuries. The NECK-PRO head
restraint sont he driver's and front-passenger
seats are moved forwards and upwards in the
event of ar ear-end collision of ac ertain severity.
This provides better head support.
If the NECK-PRO head restraint sh ave been trig-
gered in an accident ,y ou must reset the NECK-
PRO head restraint sont he driver’s and front-
passenger seat ( Y
page 51). Otherwise, the
additional protection will not be available in the
event of another rear-end collision. You can rec-
ognize when NECK-PRO head restraint sh ave
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraint sc hecked for func-
tionality at aq ualified specialist workshop after
ar ear-end collision.50
Occupant safety
Safety

heating, observe the following information: R
keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible. R

switch on the seat heating. The seat heat-
ing should also not be used to dry the seats. R
clean the seat covers as recommended;
see the "Interior care" section. R
do not transport heavy loads on the seats.
Do not place sharp object sont he seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-

als, e.g. blankets ,c oats, bags, seat covers,
child seats or booster seats.
! Make sure that there are no object sint he
footwell under or behind the seats when mov-
ing the seats back. There is ar isk that the
