Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes. Warning!
G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush the affect-
ed area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.iThe memory function (

52 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
Seat belts
Emergency tensioning device
Airbags
Child seats
Child seat recognition
As independent systems their protective
effects work in conjunction with each oth-
er.The
1
warning lamp in the instrument
cluster lights up for about 4 seconds when
you turn the key in the starter switch to po-
sition 1 or 2, or press the KEYLESS-GO* (if
so equipped) start/stop button once or
twice. It goes out when you start the en-
gine. This shows that the restraint systems
are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately 4
seconds or if it comes on thereafter, a mal-
function in the system has been detected.
More information can be found in the
"Practical hints" section (
page 252).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 62).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in inju-
ry.
Improper work on the restraint systems can
lead to unintentional deployment or opera-
tional failure.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by an authorized Mercedes-Benz
Center.
56 Safety and SecurityOccupant safety
When you sell your vehicle, we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc., over the steering
wheel hub, passenger front airbag cov-
er, or door trim panels, and installation
of additional electrical /electronic
equipment on or near SRS components
and wiring. Keep area between airbags
and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
An airbag system component within the
steering wheel gets hot after the airbag
has inflated. Do not touch.
Improper work on the system, including
incorrect installation and removal, can
lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work
there is a risk of rendering the SRS inop-
erative or causing unintended airbag de-
ployment. Work on the SRS must
therefore only be performed by an au-
thorized Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.
Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.
