ation is not high. Conversely, air bags may be
deployed even though the vehicle suffers only
minor deformation. This is the case if, for
example, very rigid vehicle parts such as longi-
tudinal body members are hit, and sufficient
deceleration occurs as a result.
If the restraint system control unit detects a
side impact or if the vehicle rolls over, the
applicable components of the restraint system
are deployed independently of each other
depending on the apparent type of accident.
R Side impact air bag and pelvis air bag on the
side on which an impact occurs, independ-
ent from the Emergency Tensioning Device
and seat belt usage
The side impact air bag on the front
passenger side deploys under the following
conditions:
- the OCS system detects that the front
passenger seat is occupied or
- the seat belt buckle tongue is engaged in
the belt buckle of the front passenger
seat
R Window curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the front-
passenger seat is occupied
R Emergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
R Window curtain air 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 addi-
tional protection to that provided by the
seat belt
i Not all air bags are deployed in an acci-
dent. The various air bags work independ-
ently of each other.
How the air bag works is determined by the
severity of the accident detected, especially
the vehicle deceleration or acceleration and
the apparent type of accident:
R Head-on collision
R Side impact
R Rollover Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R the hazard warning lamps are switched on
R the emergency lighting in the interior is acti-
vated
R the vehicle doors are unlocked
R the front side windows are lowered
R air-recirculation mode is activated
R climate control is switched off
R the engine is switched off and the fuel sup-
ply is cut off Children in the vehicle
Important safety notes
Accident statistics show that children secured
on the rear seats are safer than children
secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you fit
the child restraint system to a rear seat. The
child is generally better protected there.
If a child younger than twelve years old 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 vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R always observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's instruc-
tions.
R always observe the instructions and safety
notes on the "Occupant Classification Sys-
tem (OCS)" ( Y page 54). G
WARNING
If children are left unsupervised in the vehi-
cle, they could, in particular:
R open doors, thereby endangering other
persons or road users.
R get out and be struck by oncoming traffic.
R operate vehicle equipment and become
trapped, for example.60

Safety

All child restraint systems must meet the fol-
lowing standards:
R U.S. Federal Motor Vehicle Safety Standards
213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found on
an instruction label on the child restraint sys-
tem. This confirmation can also be found in
the installation instructions that are included
with the child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint. LATCH-type (ISOFIX) child seat
securing system
G
WARNING
For LATCH-type (ISOFIX) child restraint sys-
tems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg
).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISO-
FIX) child seat securing system may be over-
loaded, and the child may not be restrained
in an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg),
use only a LATCH-type (ISOFIX) child
restraint system in which the child is also
secured with the vehicle seat belt. Also
secure the child restraint system with the
Top Tether belt, if available.
Regularly check that the permissible gross
weight of the child together with the child
restraint system is still maintained.
Always comply with the manufacturer's instal-
lation and operating instructions for the child
restraint system used. Before installing a child seat, move the rear
seat backrest to an upright position. Do not
adjust the backrest of a seat with a LATCH-
type (ISOFIX) child restraint system installed.
Before every trip, make sure that the LATCH-
type (ISOFIX) child restraint system is engaged
correctly in both LATCH-type (ISOFIX) securing
rings
! When fitting the child restraint system in
vehicles with a rear bench seat, make sure
that the seat belt for the center seat does
not get trapped. Otherwise, the seat belt
could be damaged. :
LATCH-type (ISOFIX) securing rings (basic
illustration)
X Install the LATCH-type (ISOFIX) child
restraint system on both LATCH-type (ISO-
FIX) securing rings :.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
certain rear seats. LATCH-type (ISOFIX) secur-
ing rings : for a LATCH-type (ISOFIX) child
restraint system are installed between the
seat cushion and the seat backrest.
Non-LATCH-type (ISOFIX) child seats may also
be used and can be installed using the vehi-
cle's seat belt system. Install the child seat
according to the manufacturer's instructions. Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with a LATCH-type (ISOFIX) system and the
vehicle. This helps reduce the risk of injury
even further. If the child restraint system is
equipped with a Top Tether belt, this should
always be used. Children in the vehicle

twisted.
X Tension Top Tether belt ?. Always comply
with the child restraint system manufactur-
er's installation instructions when doing so.
X Move head restraint : back down again
slightly if necessary (Y page 93). Make
sure that you do not interfere with the cor-
rect routing of Top Tether belt ?. Child restraint system on the co-driv-
er's seat
General notes Accident statistics show that children secured
in the rear seats are safer than children
secured in the front seats. For this reason,
Mercedes-Benz strongly advises that you
install a child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the co-driver's seat, be
sure to observe the instructions and safety
notes on the "Occupant Classification System
(OCS)"

(Y page 54).
This will help to rule out any risks that may
arise due to:
R an incorrectly categorized person in the co-
driver's seat
R an unintentionally deactivated co-driver's air
bag
R an unfavorable positioning of the child
restraint system, e.g. too near to the dash-
board
Rearward-facing child restraint system If circumstances require you to install a rear-
ward-facing child restraint system on the co-
driver's seat, you must always make sure that
the co-driver's air bag is deactivated. The co-
driver's air bag is deactivated only when the
PASSENGER AIR BAG OFF indicator lamp is lit
continuously ( Y page

54).
Always comply with the manufacturer's instal-
lation and operating instructions for the child
restraint system.
Forward-facing child restraint system If it is absolutely necessary to secure a child in
a forward-facing child restraint system on the
co-driver's seat, you must always move the co-
driver's seat as far back as possible. The base
of the child restraint system must always rest
on the seat cushion of the co-driver's seat. As
much as possible of the backrest of the child
restraint system must be resting on the back-
rest of the co-driver's seat. The child restraint
system may not touch the roof or be subjected
to a load by the head restraint. Adjust the
angle of the seat backrest and the head
restraint position accordingly. Always make
sure the shoulder belt is correctly secured,64

adjust the seats, particularly when unatten-
ded. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle. G
WARNING
You could lose control of your vehicle if you
do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint,
steering wheel and mirror and fasten your
seat belt before starting the engine. G
WARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on
the seat guide rail. There is a risk of injury.
When adjusting a seat, make sure that no
one has any body parts in the sweep of the
seat. G
WARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control
of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle. G
WARNING
The front-air bags for could also injure the
vehicle occupants in the front If the front
seats are positioned too close to the dash-
board or steering wheel. This poses an
increased risk of injury or even fatal injury.
Always adjust the front seats so that they
are as far from the front air bags as possi-
ble. Also observe the notes on the correct
adjustment of the seats. G
WARNING
The seat belt does not offer the intended
level of protection if you have not moved the
backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the back-
rest is in an almost vertical position and that
the shoulder section of your seat belt is
routed across the center of your shoulder. G
WARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased
risk of injury in the head and neck area, e.g.
in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level. Seats

To prevent damage to the seats and the
seat heating, observe the following notes:
R Do not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does
get spilled on the seats.
R If the seat covers are damp or wet, do not
switch on the seat heating. Also, do not
use the seat heating 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 pointed objects on
the seat cushions such as knives, nails or
tools. Where possible, use the seats only
for carrying passengers.
R When operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
R When the seat heating is switched on, the
seat surface can be damaged as a result
of objects being placed on the seats, for
example, seat cushions, child seats and
protective covers not approved by
Mercedes-Benz.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
R Position the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
R Your arms should be slightly bent when you
are holding the steering wheel.
R Avoid seat positions that prevent the seat
belt from being correctly routed. The shoul-
der section of the belt must be routed over
the middle of your shoulder and be pulled
tight against your upper body. The lap belt
must always pass across your lap as low
down as possible, i.e. over your hip joints.
R Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
