Important safetynotes
GWARNING
If you do not have the prescribed service/
maintenanc ework or any required repairs
carried out, this can result in malfunctions or system failures. There is arisk of an accident.
Always have the prescribed service/mainte-
nanc ework as well as any required repairs
carried out at aqualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
checkt he vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardiz ethe operatin gsafety of
the vehicle. There is an increased risk of an
accidenta nd injury.
Never tamper with the wiring as well as elec-
tronic component sortheir software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
!There is arisk of damage to the vehicle if:
Rthe vehicle becomes stuck ,e.g. on ahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or ahole in the road
Raheavy objec tstrikes the undercarriage or
parts of the chassis
In situation slike this, the body, the undercar-
riage, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catc hfire.
In such situations, have the vehicle checked
and repaired immediately at aqualified spe-
cialist workshop. If on continuin gyour jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aqualified spe-
cialist workshop.

Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
Rseat belt system
Rair bags
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 40)
Rhave adjusted their seat and head restraint
properly (Ypage 82).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 82). You also have to make sure that an air bag can
inflate properly if deploye
d(
Ypage 42).
An air bag supplements acorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accident occurs, only
the air bags that increase protection in that par- ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against object spenetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 48).
For information on children traveling with you in
the vehicle and on child restraint systems, see
"Children in the vehicle" (
Ypage 51).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate aperson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
AssistanceC enter at 1-800-FOR-MERCedes
(1‑800‑36 7‑6372).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the engine is running.
Therefore, malfunction scan be detected in
good time.

General notes
The multimedia system section in this manual
describes the basicprinciples for operation.
More information can be found in the Digital
Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
municatio nequipment integrated in the vehi-
cle whil edriving, you wil lbedistracted from
traffic conditions. You could also lose control
of the vehicle .There is arisk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legalr equirements for the
country in which you are currently driving when
operating the multimedia system.
The multimedia system calculates the route to
the destination withou ttaking the following into
account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rule sand regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's data.
For example:
Rad iverted route
Rthe road layout or the direction of aone-way
street has been changed
For this reason, you must alwayso bserve road
and traffic rule sand regulations during your
journey. Roa dand traffic rule sand regulations
alwaysh ave priority over multimedia system
driving recommendations.
Navigation announcements are intended to
direct you whil edriving withou tdiverting your
attention from the road and driving. Please alwaysu
se this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
traffic conditions and driving, and increase the
risk of an accident.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equip-
ment and meets the FCC radi ofrequency (RF)
Exposure Guidelines in Supplement CtoOET65.
This equipment has very low levelsofRFe nergy
that is deemedtoc omply withoutmaximum
permissive exposure evaluation (MPE). How-
ever, it is recommended to insta
ll it at
adistance
of at least 8inches (approx. 20 cm) betwee nthe
radiation source and aperson's body (not
including limbss uch as hands, wrists, feet and
legs).
GWARNING
Modifications to electronic components, their software as wel laswiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle .There is an increase drisk of an
accident and injury.
Never tamper with the wiring as wel laselec-
tronic components or their software .You
shoul dhave all work to electricala nd elec-
tronic equipment carried out at aqualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
