Important!
Airbags are designed to activate only in certain 
frontal (front airbags) impacts, or side (side impact 
airbags) impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient 
severity to meet the deployment thresholds, will 
they provide their supplemental protection.
The driver and passenger must always wear their 
seat belts, otherwise it is not possible for the airbags 
to provide their intended supplemental protection.
In cases of other frontal impacts, angled impacts, 
roll-overs, other side impacts, rear collisions, or 
other accidents in which the airbags are not 
designed to deploy, the airbags will not be activated. 
The driver and passenger will then be protected by 
the fastened seat belts.
We caution you not to rely on the presence of the 
airbags in order to avoid wearing your seat belt.
Wa r n i n g !
Airbags are designed to reduce the potential of 
injury in certain frontal (front airbags) impacts, 
and side (side impact airbags) impacts which may 
cause significant injuries, however, no system 
available today can totally eliminate injuries and 
fatalities.The activation of the “SRS” temporarily releases 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 temporary breathing difficulty for 
people with asthma 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.

which are designed to activate in certain impacts 
exceeding a preset threshold to reduce the potential 
and severity of injury. It is important to your safety 
and that of your passenger that you replace deployed 
airbags and repair any malfunctioning airbags to 
ensure the vehicle will continue to provide crash 
protection for occupants.
Wa r n i n g !
To reduce the risk of injury when the front airbags 
inflate, it is very important for the driver and 
passenger to always be in a properly seated 
position and to wear their 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 the 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. Occupants who are 
unbelted, out of position or too close to the airbag 
can be seriously injured 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 backrest.• Adjust the driver’s seat as far as possible 
rearward, still permitting proper operation of 
vehicle controls. The distance from the center 
of the driver’s breastbone to the center of the 
airbag cover on the steering wheel must be at 
least ten inches (25 cm) or more. You should be 
able to accomplish this by a combination of 
adjustments to the seat and steering wheel. If 
you have any problems, please see your 
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the 
steering wheel or dashboard.• Keep hands on the outside of steering wheel 
rim. Placing hands and arms inside the rim 
can increase the risk and potential severity of 
hand / arm injury when the driver front airbag 
inflates.• Adjust the passenger seat as far as possible 
rearward from the dashboard when the seat is 
occupied.

• Occupants, especially children, should never 
lean their heads in the area of the door where 
the side airbag inflates. This could result in 
serious injuries or death should the airbag be 
triggered. Always sit upright, properly use the 
seatbelts and appropriate size infant or child 
restraint system• Children 12 years old and under must never 
ride in this vehicle, except in a Mercedes-Benz 
authorized BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM system 
installed in the vehicle to deactivate the 
passenger front airbag when it is properly 
installed. Otherwise they will be struck by the 
airbag when it inflates in a crash. If this 
happens, serious or fatal injury can result.
Failure to follow these instructions can result in 
severe or fatal injuries to you or other occupants.
Wa r n i n g !
Should you choose to place a child 12 years old or 
under in the front passenger seat of your vehicle, 
you must properly use a BabySmart
TM child 
restraint. A BabySmart
TM child restraint will turn 
off the passenger side front airbag. BabySmart
TM 
will not, however, turn off the side impact airbag. 
It should be noted that there is a possibility for a 
side airbag related injury if occupants, especially 
children, are not properly seated or restrained 
when next to a side airbag which needs to deploy 
rapidly in a side impact in order to do its job.
To help avoid the possibility of injury, please follow 
these guidelines: (1) occupants, especially 
children, should never place their bodies or lean 
their heads in the area of the door where the side 
airbag inflates. This could result in serious 
injuries or death should the side airbag be 
activated; (2) always sit upright, properly use the 
seat belts and use an appropriately sized infant or 
child restraint system for all children 12 years old 
or under; and (3) always wear seat belts properly.

If you believe that, even with the use of these 
guidelines, it would be safer for your front 
passenger seat occupant to have the passenger side 
door mounted side airbag deactivated, then 
deactivation can be accomplished upon your 
written election to do so at your authorized 
Mercedes-Benz Center at an additional cost. Please 
contact your local authorized Mercedes-Benz 
Center or call our Client Assistance Center at 
1-800-FOR-MERCedes (1-800-367-6372) for details.Wa r n i n g !
• Damaged seat belts or belts that were highly 
stressed in an accident must be replaced and 
their anchoring points must also be checked. 
Use only belts installed or supplied by an 
authorized Mercedes-Benz Center.
• Airbags and ETR’s are designed to function on 
a one-time-only basis. An airbag or emergency 
tensioning retractor (ETR) that was activated 
must be replaced.• Do not pass belts over sharp edges.• Do not make any modification that could 
change the effectiveness of the belts.• No modifications of any kind may be made to 
any components or wiring of the “SRS”. This 
includes changing or removing any component 
or part of the “SRS”, the installation of 
additional trim material, badges etc. over the 
steering wheel hub, passenger airbag cover, 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 of objects 
(e.g. packages, purses, umbrellas, etc.).

When you sell the vehicle we strongly urge you to give 
notice to the subsequent owner that it is equipped with 
an “SRS” by alerting him to the applicable section in the 
Operator’s Manual.
• 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 unintended 
activation of the “SRS”.• In addition, through improper work there is 
the risk of rendering the “SRS” inoperative or 
causing unintended airbag deployment. Work 
on the “SRS” must therefore only be performed 
by an authorized Mercedes-Benz Center.
• For your protection and the protection of 
others, when scrapping the airbag unit or 
emergency tensioning retractor, our safety 
instructions must be followed. These 
instructions are available at your authorized 
Mercedes-Benz Center.• Given the considerable deployment speed and 
the textile structure of the airbags, there is the 
possibility of abrasions or other injuries 
resulting from airbag deployment.

USA Models only:
Since 1986 all U.S. child restraints comply with U.S. 
regulations without the use of a tether strap.
Wa r n i n g !
Children 12 years old and under must never ride in 
this vehicle, except in a Mercedes-Benz authorized 
BabySmart
TM compatible child seat, which operates 
with the BabySmart
TM system installed in the 
vehicle to deactivate the passenger front airbag 
when it is properly installed. Otherwise they will 
be struck by the airbag when it inflates in a crash. 
If this happens, serious or fatal injury can result.
Infants and small children must be seated in an 
appropriate infant or child restraint system, which 
is properly secured with the vehicle’s seat belt, 
fully in accordance with the child seat 
manufacturer’s instructions.Infants and small children should never share a 
seat belt with another occupant. During an 
accident, they could be crushed between the 
occupant and seat belt.
Children too big for child restraint systems should 
use regular seat belts. Position the shoulder belt 
across chest and shoulder, not face or neck. A 
booster seat may be necessary to achieve proper 
belt positioning for children from 41 lbs. to the 
point where a lap / shoulder belt fits properly 
without one.When the child restraint is not in use, remove it 
from the vehicle or secure it with the seat belt to 
prevent the child restraint from becoming a 
projectile in the event of an accident.Do not leave children unattended in the vehicle; 
even if the children are secured in a child restraint 
system. Unsupervised children in a child restraint 
system may use vehicle equipment and may cause 
serious personal injury.

cluster displayPractical hints Car care Index Emergency calls
An emergency call is initiated automatically:
•following an accident in which the Emergency 
Tensioning Retractors (ETR’s) or airbags deploy,
•if the antitheft alarm or the tow away alarm stays on 
for more than 20 seconds, see pages 35 and 37.
An emergency call can also be initiated manually by 
opening the cover next to the inside rear view mirror 
labeled “SOS”, then briefly pressing the button located 
under the cover. See below for instructions on initiating 
an emergency call manually.
Once the emergency call is in progress, the indicator 
lamp in the “SOS” button will begin to flash. All 
information relevant to the emergency, such as the 
location of the vehicle (determined by the GPS satellite 
location system), vehicle model, identification number 
and color are generated.
A voice connection between the Response Center and 
the occupants of the vehicle will be established 
automatically soon after the emergency call has been 
initiated. When a voice connection is established the 
audio system mutes. The Response Center will attempt 
to determine more precisely the nature of the accident 
provided they can speak to an occupant of the vehicle.The Tele Aid system is available if:
•it has been activated and is operational. Activation 
requires a subscription for monitoring services and 
cellular air time
•the relevant cellular phone network and GPS signals 
are available and pass the information on to the 
Response Center.
Note:
Location of the vehicle on a map is possible if the 
vehicle is able to receive signals from the GPS satellite 
network and pass the information on to the Response 
Center.
Wa r n i n g !
If the indicator lamp in the “SOS” button is 
illuminated continuously and there was no voice 
connection to the Response Center established, 
then the Tele Aid system could not initiate an 
emergency call (e.g. the relevant cellular phone 
network is not available).Should this occur, assistance must be summoned 
by other means.
