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. !Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state by applying plenty of water.
!If an exterior rear view mirror housing
is forcibly pushed forward or rearward,
reposition it by applying firm pressure
until it snaps into place. The mirror
housing is now properly positioned and

56 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


Lower anchors and tethers for children
(LATCH)
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 position1.


for about 4 seconds when you start the
engine by turning the key.The warning lamp goes out shortly after
you start the engine. This shows that the
restraint systems are operational.
A malfunction in the system has been de-
tected if the
1
warning lamp:


fails to extinguish after approximately
4seconds.


does not come on at all.


comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
More information can be found in the
“Practical hints” section (
page 253).
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 65).
iThe warning lamp remains lit if the key
is turned to position2 and left there.
The warning lamp will go out when you
start the engine.

Airbags
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, in-
cluding 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 inoperative or
causing unintended airbag deployment.
W o r k o n t h e S R S m u s t t h e r e f o r e o n l y b e p e r -
formed by an authorized Mercedes-Benz
Center.
Warning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact and head protec-
tion window curtain airbags) impacts which
may cause significant injuries. However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear your
seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and ensure that it is properly
positioned on your body.
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:

Sit properly belted in an upright position
with your back against the seat back-
rest.

61 Safety and Security
Occupant safety
The front passenger airbag will only be de-
ployed if:

the front passenger seat is occupied


the
7
indicator lamp in the center
console is not lit (
page 67)
1Driver airbag
2Passenger airbagSide impact airbags, window curtain
airbags
The side impact airbags and window cur-
tain airbags are deployed:


on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The side impact airbags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.The front passenger side airbag will only
deploy if the system senses that the front
passenger seat is occupied.

Seat belts
The seat belt nonusage warning lamp
<

in the instrument cluster lights up and a
warning sounds for a short time when you
turn the key in the starter switch to
position2 and the driver’s seat belt is not
fastened.
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

74 Safety and SecurityDriving safety systemsContinuous steady brake pedal pressure
yields the advantages provided by ABS,
namely braking power and ability to steer
the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.ABS control
The
-
malfunction indicator lamp in the
speedometer lights up when you turn the
key in the starter switch to position2. It
goes out when the engine is running.
More information can be found in the
“Practical hints” section (
page 255).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!
G
ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.

75 Safety and Security
Driving safety systems
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance. 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.
More information can be found in the
“Practical hints” section (
page 262).
ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful while driving off and on wet or slip-
pery road surfaces.
The ESP warning lamp
v
in the speed-
ometer dial flashes when the ESP is en-
gaged.
The warning lamp
v
in the speedome-
ter dial lights up when you turn the key in
the starter switch to position2. It goes out
when the engine is running.
Warning!
G
BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction afforded. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a BAS equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
