63 Safety and Security
Occupant safety
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a spe-
cial seat belt retractor for the secure fas-
tening of child restraints.
To fasten a child restraint follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During the seat belt retraction a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.
!The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories,
and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by a
lap-shoulder belt, and that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor
Vehicle Safety Standard 213.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to inside of vehicle and to infant
or child restraints.Warning!
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 ve-
hicle to deactivate the passenger side front
airbag when it is properly installed. Other-
wise they will be struck by the airbag when
it inflates in a crash. If this happens, serious
or fatal injury will result.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly secured with the vehicle’s seat belt,
fully in accordance with the child seat
manufacturer’s instructions.

BabySmart
TM airbag deactivation
system
Special BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Center, are
required for use with the BabySmart
TM air-
bag deactivation system. With the special
child seat properly installed, the passenger
front airbag will not deploy.
BabySmart
TM is a trademark of Siemens
Automotive Corp.
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.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Adjust the passenger seat as far as possible
rearward from the dashboard when the seat
is occupied.
Warning!
G
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 neces-
sary to achieve proper belt positioning for
children from 41 lbs. until they reach a
height where a lap/shoulder belt fits proper-
ly without a booster.
When the child restraint is not in use, re-
move 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 ac-
cident.
Do not leave children unattended in the ve-
hicle; even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause serious
personal injury.

After turning the key in the starter switch
to position1 or2, the 7
indicator lamp
located on the glove box lights up for ap-
prox. 6 seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.
iThe system does not deactivate the
head-thorax airbag and the emergency
tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart compatible child
seat on the front passenger seat, the front
passenger airbag will not deploy only if the 7
indicator lamp remains illuminated.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.

66 Safety and SecurityOccupant safetyWarning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
passenger seat. Signals from such devices
may interfere with the BabySmart
TM system.
Such signal interference may cause the

ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
If the ABS activates during braking, the
ABS/ESP warning lamp
v
in the speed-
ometer dial flashes. Because of the SBC
brake system, you will not feel any pulsa-
tion in the brake pedal.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, and SBC is only achieved with win-
ter tires (M + S tires), or snow chains as
required.
Warning!
G
The following factors increase the risk of ac-
cidents:

excessive speed, especially in turns


wet and slippery road surfaces


following another vehicle too closely
ABS, BAS, ESP and SBC cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal, rather use
firm, steady brake pedal pressure. Pumping
the brake pedal defeats the purpose for ABS
and significantly reduces braking effective-
ness.

69 Safety and Security
Driving safety systems
The
-
warning lamp in the speedome-
ter (
page 21) lights up when you turn the
key to position1 or2. It goes out when the
engine is running.
Flashing warning lamp while braking
The v
warning lamp flashes whenever
the ABS is activated. Always adapt your
driving style to the prevailing road and
weather conditions.

When the ABS is in the regulating
mode, continue to apply pressure on
the brake pedal.
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 potential-
ly 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.
Warning!
G
The 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.
