the56 indicator 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 56 indicator lamp will
illuminate and not go out.
Warning!G
If the 1indicator lamp and the
56indicator lamp are lit at the same
time, there is a malfunction in the Occupant
Classification System. The front passenger
front air bag will be deactivated in this case.
Have the system checked as soon as possi-
ble by qualified technicians. Contact an au-
thorized Mercedes-Benz Center.
Only have the seat repaired or replaced at
an authorized Mercedes-Benz Center.

air bag system and OCS:

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.

Driving safety systems
For more information, see the “Practical
hints” section (
page 384) and
(
page 394).
Warning!G
Never switch off the ESP® when you see the
ESP® warning lamp v flashing in the
instrument cluster. 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 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 by the exist-
ing road and tire conditions. 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
capabilities of an ESP
® equipped vehicle
must never be exploited in a reckless or dan-
gerous manner which could jeopardize the
user’s safety or the safety of others.
iThe ESP® will only function properly if
you use wheels of the recommended tire
size (
page 482).
!Because the ESP® operates automatically,
the engine and the ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO* start/stop button in 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 brake system.
