The multicontour backrest is equipped with a
massage function to help prevent fatigue during
longer journeys.
The PULSE function inflates and deflates the air
cushions in the backrest rhythmically.
An indicator lamp on the switch lights up when the
PULSE function is switched on. The PULSE function
switches off automatically after approximately
5minutes.
Note:
If the top cushion is inflated, only the middle air
cushion is inflated and deflated.Seat heater
The seat heaters can be switched on with the electronic
key in starter switch positions 1 or 2.
The buttons are located on each door.
Note:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time or if the battery charge is low. In this case, one or
both indicator lamps will blink.
The seat heaters switch back on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.

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 7 indicator lamp located on 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 7 indicator lamp located on 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 308 for
notes on the 7 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 7 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.

Inside rear view mirror
Manually adjust the inside rear view mirror.
Storing inside rear view mirror positions
The inside rear view mirror positions are stored in
memory with the seat / steering wheel / exterior rear
view mirror positions and can be recalled when
necessary. See page 108 for notes on the memory
function.
Inside rear view mirror, automatic antiglare
Antiglare mode:
With the electronic key in starter switch position 2, the
mirror reflection brightness responds to changes in
light sensitivity.
With the gear selection lever in position “R”, or with the
interior light switched on, the mirror brightness does
not respond to changes in light sensitivity.Note:
The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
inside rear view mirror.
The automatic antiglare function will not react for
example, if the rear window sun shade is in the raised
position.
Wa r n i n g !
In the case of an accident liquid electrolyte may
escape the mirror housing when the mirror glass
breaks.Electrolyte has an irritating effect. Do not allow the
liquid to come into contact with eyes, skin,
clothing, or respiratory system. In cases it does,
immediately flush affected area with water, and
seek medical help if necessary.
