child seat installed
After turning the key in the starter switch
to position1 or2, the 7
indicator lamp
located in the center console lights up for
approx. 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.
More information can be found in the
“Practical hints” section (page 251).

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
TM compatible
child seat on the front passenger seat, the
front passenger airbag will not deploy only if
the
7
indicator lamp remains illuminat-
ed.
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
BabySmartTM restraint to transport children
on the front passenger seat until the system
has been repaired.

iFor operation in the USA only: This de-
vice complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any inter-
ference received, including interfer-
ence that may cause undesired
operation.
Any unauthorized modification to this

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 247).
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 254).
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. The
ABS cannot prevent accidents, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ABS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.

75 Safety and Security
Driving safety systems
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
The 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. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities 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.
Warning!
G
Never switch off the ESP when you see the
ESP warning lamp
v
flashing in the
speedometer dial. In this case proceed as
follows:


While driving off, apply as little throttle
as possible.


While driving, ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.

76 Safety and SecurityDriving safety systems
More information can be found in the
“Practical hints” section (
page 246).Switching off the ESP
To improve the vehicle’s traction, turn off
the ESP in driving situations where it would
be advantageous to have drive wheels spin
and thus cut into surfaces for better grip
such as:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


sand or gravel
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
!Because of the ESP’s automatic opera-
tion, the engine must be shut off (key in
starter switch position0 or1) when

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
rear axle brake system.
The ESP will only function properly if
you use wheels of the recommended
tire size.
Warning!
G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.

Anti-theft alarm system*
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens

a door


the trunk lid


the hood.
The alarm will stay on even if the activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when


someone attempts to raise the vehicle


the vehicle is opened with the mechan-
ical key.Arming the alarm system
The alarm system is armed after locking
the vehicle with the SmartKey. The turn
signal lamps blink three times to indicate
that the alarm system is activated. The in-
dicator lamp in the switch for the tow-away
alarm will blink after approximately 10 sec-
onds when the alarm system is completely
armed (
page 80).
iIn case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Center
or call 1-800-FOR-MER-Cedes (in the
USA), or 1-800-387-0100 (in Canada).
iIf the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid sys-
tem* provided Tele Aid service was
subscribed to and properly activated,
and that necessary cellular service and
GPS coverage are available.iIf the turn signal lamps do not blink
three times one of the following ele-
ments may not be properly closed:

a door


the trunk lid


the hood
Close the respective element and lock
the vehicle again.
