52 Safety and SecurityOccupant safety
Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice (
page 366), the 59
indicator lamp1 located in the dash-
board illuminates. If an adult occupant is
properly sitting on the front passenger
seat and the system senses the occupant
as being an adult, the 59 indi-
cator lamp will illuminate and go out after
approximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 59indicator lamp
will illuminate and not go out.For more information, see the “Practical
hints” section (
page 620).
Do not hang anything from or attach any
items to the seats.
Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.
Do not move the front passenger seat
backwards against stiff objects.
Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
While seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result
in the OCS being unable to correctly ap-
proximate the occupant’s weight
category.
Do not lift yourself from the seat as this
may cause the OCS to be unable to cor-
rectly approximate the occupant weight
category.
Read and observe all warnings in this
chapter.
Warning!
G
If the 59 indicator lamp should
not illuminate, the system is not functioning.
You must contact an authorized
Mercedes-Benz Center before seating any
child on the front passenger seat.
Warning!
G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification System.
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 increasing protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.

Blocking of rear side window operation
You can block the rear side window opera-
tion (for instance when you have children

selves, e.g. by becoming trapped in the win-
dow opening.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an

cess to a vehicle could result in an accident
and/or serious personal injury.
i
Operation of the rear side windows with the
switches located in the driver’s door is still pos-
sible.

section (
page 614) and (
page 622).
Warning!
G
Never switch off the ESP
® when you see the
ESP
® warning lamp v flashing in the in-
strument cluster. In this case proceed as fol-
lows:
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 result-
ing from excessive speed.
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.
i
DISTRONIC Plus* and cruise control are
switched off when the ESP
® engages.
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 727).
!
Because the ESP
® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when
the electronic parking brake is being tested
on a brake test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.

Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey or SmartKey with KEYLESS-GO*
with you, and lock the vehicle. The engine
can be started by anyone with a valid
SmartKey or SmartKey with KEYLESS-GO*
that is left inside the vehicle.
Activating
With the SmartKey: Remove the
SmartKey from the starter switch.
With the KEYLESS-GO*: Turn off the
engine (
page 366) and open the driv-
er’s door.
Deactivating
Switch on the ignition (
page 365).
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
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
the vehicle is opened with the
mechanical key
a door is opened from the inside
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(
page 80).
i
Starting the engine will also deactivate the
immobilizer.
In case the engine cannot be started (yet the ve-
hicle’s battery is charged), the system is not op-
erational. Contact an authorized Mercedes-Benz
Center or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).
