With the easy-entry/exit feature activated the steering
wheel tilts upwards and the driver’s seat moves
rearwards, when removing the electronic key from the
starter switch or when opening the driver’s door and the
electronic key in starter switch position 0 or 1.
This allows easier entry into and exit from the vehicle
when the driver’s door is opened.
The easy-entry /exit feature can be switched on or off in
the individual setting menu “CONVENIENCE” –
“EASY-ENTRY FEATURE ACTIVATE”, see page 134.

Front seat adjustment
To operate the front power seat adjustment switches,
turn the electronic key in starter switch to position 1
or 2 (with respective door open, the power seats can
also be operated with the electronic key removed or in
starter switch position 0).
Wa r n i n g !
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.Never ride in a moving vehicle with the seat back
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or fatal injuries. The seat back
and seat belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body.Never place hands under seat or near any moving
parts while a seat is being adjusted.
When leaving the vehicle always remove the
electronic key from the starter switch, and lock
your vehicle. The power seats can also be operated with the
driver’s or front passenger door open. Do not leave
children unattended in the vehicle, or with access
to an unlocked vehicle. Unsupervised use of vehicle
equipment may cause serious personal injury.

USE SEAT BELTS PROPERLY.• Seat belts can only work when used properly.
Never wear seat belts in any other way than as
described in this section, as that could result
in serious injuries in case of an accident.• E ach occupan t s houl d wear t hei r s ea t bel t a t al l
times, because seat belts help reduce the
likelihood of and potential severity of injuries
in accidents, including rollovers. The
integrated restraint system includes “SRS”
(driver airbag, front passenger airbag, side
impact airbags, head protection window
curtain airbags for side windows), “ETR” (seat
belt emergency tensioning retractors), and
front seat knee bolsters. The system is
designed to enhance the protection offered to
properly belted occupants in certain frontal
(front airbags) and side (side impact and
window curtain airbags) impacts which exceed
preset deployment thresholds.
• Never wear the shoulder belt under your arm, against your neck or off your shoulder. In a
crash, your body would move too far forward.
That would increase the chance of head and
neck injuries. The belt would also apply too
much force to the ribs or abdomen, which
could severely injure internal organs such as
your liver or spleen.• Never wear belts over rigid or breakable objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.• Position the lap belt as low as possible on your hips and not across the abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person or
other objects.• Belts should not be worn twisted. In a crash, you wouldn’t have the full width of the belt to
manage impact forces. The twisted belt against
your body could cause injuries.

BabySmart
TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed
for use with the Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are required for
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the
passenger front airbag will not deploy.
The ü indicator lamp located in the center console
will be illuminated, except with electronic key removed
or in starter switch position 0. The system does not
deactivate the door mounted side impact airbag.
Self-test BabySmart
TM without special child seat
installed
After turning electronic key in starter switch to
position 1 or 2, the ü indicator lamp located in the
center console comes on for approximately 6 seconds
and then extinguishes.
If the indicator lamp should not come on or is
continuously lit, the system is not functioning. You must
see an authorized Mercedes-Benz Center before seating
any child on the front passenger seat. See page 289 for
notes on the ü indicator lamp.
BabySmart
TM is a trademark of Siemens Automotive Corp.
Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation 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 protecting
the child.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the ü indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.

Emergency tensioning retractor (ETR)
The seat belts for the front and rear seats are equipped
with emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the electronic key in
starter switch position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.
In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.
Note:
The front passenger ETR activates only if the front
passenger seat is occupied.
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy and the ETR to activate in a crash exceeding the
appropriate threshold.
