Vehicle data recording
Vehicle data recording
Information regarding electronic
recording devices
(Including notice pursuant to California Code § 9951)
Please note that your vehicle is equipped with devices that can record vehicle systems data and, if equipped with the Tele Aid system,
may transmit some data in certain accidents.
This information helps, for example, to diagnose vehicle systems after a collision and to continuously improve vehicle safety.
DaimlerChrysler may access the information and share it with others

for safety research or vehicle diagnosis purposes

with the consent of the vehicle owner or lessee

in response to an official request by law enforcement or other government agency

for use in dispute resolution involving DaimlerChrysler, its affiliates or sales/service organization and/or

as otherwise required or permitted by law.
Please check the Tele Aid subscription service agreement for details regarding the information that may be recorded or transmitted
via that system.

50 Getting started
Driving
Driving off
Depress the brake pedal.
The gear selector lever lock is released.
Place the gear selector lever in drive
positionD or reverse gearR.
Release the brake pedal.
Carefully depress the accelerator
pedal.After a cold start, the transmission engag-
es at a higher revolution. This allows the
catalytic converter to reach its operating
temperature earlier.
Warning!G
It is dangerous to shift the gear selector le-
ver out of park positionP or neutralN if the
engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward
or in reverse. You could lose control of the
vehicle and hit someone or something. Only
shift into gear when the engine is idling nor-
mally and when your right foot is firmly on
the brake pedal.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
!In order to avoid damage to the
transmission:

Wait for the gear selection process to com-
plete before setting the vehicle in motion.

Place the gear selector lever in reverse
gearR or park positionP only when the vehi-
cle is stopped.
!If you hear a warning signal and the mes-
sage
Release parking brake
appears in the multifunction display when driving
off, you have forgotten to release the parking
brake.
Release the parking brake (
page 49).
!Do not run cold engine at high engine speed.
Running a cold engine at high engine speed may
shorten the service life of the engine.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.
iOnce the vehicle is in motion, the automatic
central locking system engages.
You can deactivate the automatic locking using
the control system (
page 139).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.

63 Safety and Security
Occupant safety

Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.

Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should
the air bag be deployed. Always sit as
upright as possible, properly use the
seat belts and an appropriately sized in-
fant, or toddler restraint, or booster seat
recommended for the size and weight of
the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, are not properly seated or restrained
when next to a head-thorax air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts, and for children
12 years old or under, use an appropri-
ately sized infant, or toddler restraint, or
booster seat recommended for the size
and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
passenger seat occupants to have the pas-
senger head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written request to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center (in the USA) at
1-800-FOR-MERCedes (1-800-367-6372) or
Customer Service (in Canada) at
1-800-387-0100 for details.

67 Safety and Security
Occupant safety
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the passenger front air
bag and passenger-side knee air bag on or
off based on the classified occupant
weight category determined by weight
sensor readings from the passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category. Both driver and the passenger should
always use the PASSENGER AIR BAG OFF
indicator lamp (
page 70) as an indica-
tion of whether or not the passenger is
properly positioned.
iThe system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.
iIf the seat needs to be serviced in any way,
take the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used. Warning!G
If the PASSENGER AIR BAG OFF indicator
lamp illuminates when an adult or someone
larger than a small individual is in the pas-
senger seat, have the passenger re-position
himself or herself in the seat until the
PASSENGER AIR BAG OFF indicator lamp
goes out.
For information on air bag display
messages, see (
page 319).
In the event of a collision, the air bag control
unit will not allow passenger front air bag or
passenger knee air bag deployment when
the OCS classified the passenger seat occu-
pant as being up to or less than the weight
of a typical 12-month-old child in a standard
child restraint or if the passenger seat is
sensed as being empty.

117 Controls in detail
Control system
Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1. The control system
enables you to

call up information about your vehicle

change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster
display, and much more.
The control system relays information to
the multifunction display.
Multifunction display
The multifunction display consists of the
display fields in the speedometer and the
tachometer. In its default state, the left
display field shows the outside tempera-
ture and main odometer, while the trip
odometer and the clock appears in the
right display field. This default setting is
referred to as the standard display.

Warning!G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions
permit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
