In general, this technical information docu-
ment st he state of ac omponent, am odule, a
system or the surroundings.
These include, for example: R
operating conditions of system components,
e.g. fluid levels R
the vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment ,l ateral acceleration, accelerator pedal

This data is of an exclusively technical nature
and can be used to: R
assist in recognizing and rectifying malfunc-
tions and defects R
analyze vehicle functions, e.g. after an acci-

The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. More detailed infor-
mation is obtained from it, if required.
After am alfunction has been rectified, the infor-
mation is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec-
tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to ap erson.
Examples include: R
accident reports R
damage to the vehicle R
witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
example, vehicle location in case of an emer-
gency.
COMAND/mbrace (Canada: TELEAID) If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Operator's

Event dat ar ecordersThis vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an ED Ristor ecord, in certain crash or near
crash-lik es ituations, such as an air bag deploy-
ment or hittin gar oad obstacle, data that will
assist in understanding how av ehicle's systems
performed. The ED Risd esigned to record data
related to vehicle dynamics and safety systems
for as hort period of time, typically 30 seconds
or less. The ED Rint his vehicle is designed to record
such data as: R
How various systems in your vehicle were
operating R
Whether or not the driver and passenger
safety belts were buckled/fastened R
How far (if at all) the driver was depressing the
accelerator and/or brake pedal and R
How fast the vehicle was traveling.
These data can help provide ab etter under-
standin goft he circumstances in which acci-
dents and injuries occur. NOTE: ED Rd ata are
recorded by your vehicle only if an on-trivial
crash situation occurs; no data is recorded by
the ED Ru nder normal driving conditions and no
personal data (e.g. name, gender, age and acci-
dent location) are recorded. However, other par-
ties, such as law enforcement could combine
ED Rd ata with the type of personally identifying
data routinely acquired during ac rash investi-
gation.
Access to the vehicle and/or the ED Risn eeded
to read data that is recorded by the EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment ,c an read the information by accessing the
vehicle or the EDR.
ED Rd ata may be used in civil and criminal mat-
ters as at ool in accident reconstruction, acci-
dent claims and vehicle safety. Sinc et he Crash
Data Retrieval CDR tool that is used to extract
data from the ED Risc ommercially available,
Mercedes-Benz USA ,L LC ("MBUSA") expressly
disclaims any and all liability arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share ED Rd ata with others
without the consen toft he vehicle owners or, if

tions.
Forward-facing child restraint system If you secur eac hild in af orward-facin gc hild
restraint system on the front-passenge rs eat,
always move the front-passenge rs eat as far
back as possible .T he entire base of the child
restraint system must always rest on the seat
cushio noft he front-passenge rs eat. The back-
rest of the child restraint system must lie as flat
as possible against the backrest of the front-
passenger seat. The child restraint system must
not touc ht he roof or be subjected to al oad by
the head restraint .A djust the angle of the seat
backrest and the head restraint position accord-
ingly. Always make sure that the shoulder belt
strap is correctly routed fro mt he front-
passenger seat belt loop to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards and
downwards fro mt he front-passenge rs eat belt

good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintain as afe distance
from the vehicle in front .D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section ( Y
page 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such aw ay that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from as peed of about 5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally ,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aq ualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 204) and dis- play messages which may be shown in the
instrument cluster ( Y
page 179).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make af ull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extr ac are while driving.
BAS (Brake Assist System)
General information BAS operates in emergenc yb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If BAS is malfunctioning, the braking distance
in an emergenc yb raking situation is
increased. There is ar isk of an accident.
In an emergenc yb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergenc yb raking situation is over.
ABS prevent st he wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.Driving safety systems 55
