To operate the front power seat adjustment switches, 
turn electronic key in steering lock to position 1 or 2 
(with the driver’s or passenger’s door open, the power 
seats can also be operated with the electronic key 
removed or in steering lock position 0).
Warning!
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 backrest 
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 even fatal injuries. The 
backrest and seat belt provide the best restraint 
when the wearer is in an upright position and the 
belt is properly positioned on the body.Never place hands under seat or near any moving 
parts while a seat is being adjusted.
Wa r n i n g !
When leaving the vehicle always remove the 
electronic key from the steering lock, and lock your 
vehicle.The power seats can also be operated with the 
driver’s or 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.

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 
steering lock position 0. The system does not deactivate 
the door mounted side impact airbag.
BabySmart
TM is a trademark of Siemens Automotive Corp.
Self-test BabySmart
TM 
without special child seat installed
After turning electronic key in steering lock to 
position 1 or 2, the 7 indicator lamp located on the 
center console comes on for approx. 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.

Warning!
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.
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.

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.
• In addition, through improper work there is 
the risk of rendering the “SRS” inoperative or 
causing unintended airbag 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.Infant and child restraint systems
We recommend all infants and children be properly re-
strained at all times while the vehicle is in motion. All 
lap-shoulder belts except the driver’s seat belt have 
special seat belt retractors for secure fastening of child 
restraints.
To activate, pull shoulder belt out completely and let it 
retract. During the seat belt retraction a ratcheting 
sound can be heard to indicate that the special seat belt 
retractor is activated. The belt is now locked.
To deactivate, release seat belt buckle and let seat belt 
retract completely. The seat belt can again be used in 
the usual manner.
Warning!
Never release the seat belt buckle while vehicle is 
in motion, since the special seat belt retractor will 
be deactivated.
