even at vehicle speeds of approximately 9 mph
(15 km / h) or more.If a door is opened from the inside at speeds of
approximately 9 mph (15 km / h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the automatic central locking activated and the
electronic key in steering lock position 2, the vehicle
doors will lock if the left front wheel as well as the right
rear wheel spin at vehicle speeds of approximately
9 mph (15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after a
strong deceleration is detected, such as in a collision
(this is intended to aid rescue and exit).

cluster displayPractical hints Car care Index
When you sell the vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an “SRS” by alerting him to the applicable section in the
Operator’s Manual.
• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free of objects (e.g.
packages, purses, umbrellas, etc.).• Do not use handles above doors for placing
such items as coat hangers etc.• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.
• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.• In addition, through improper work there is
the risk of rendering the “SRS” inoperative or
causing unintended deployment. Work on the
“SRS” must therefore only be performed by an
authorized Mercedes-Benz Center.• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available at your authorized
Mercedes-Benz Center.• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.

Programming or reprogramming the integrated
remote control:
1. Turn electronic key in steering lock to position 1
or 2.
2. Hold the end of the hand-held transmitter of the
device you wish to train approximately 2 to 5 inches
(5 cm to 12 cm) away from the surface of the
integrated remote control located on the inside rear
view mirror, keeping the indicator lamp in view.
3. Using both hands, simultaneously push the hand-
held transmitter button and the desired integrated
remote control button. Do not release the buttons
until completing step 4.4. The indicator lamp on the integrated remote control
will flash, first slowly and then rapidly. When the
indicator lamp flashes rapidly, both buttons may be
released (the rapid flashing lamp indicates
successful programming of the new frequency
signal). To program the remaining two buttons,
follow steps 1 through 4.
Note:
If, after repeated attempts, you do not successfully
program the integrated remote control device to learn
the signal of the hand-held transmitter, the garage door
opener could be equipped with the “rolling code
feature”.
