BabySmart™ Airbag Deactivation System
Special child seats, designed for use with the Mercedes-Benz system and available at any
authorized Mercedes-Benz dealer are required for use with the BabySmart™ airbag deactivation
system. With the special child seat properly installed, the passenger front airbag will not deploy. The
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 is a trademark of Siemens Automotive Corp.
Warning !
The BabySmart™ Airbag Deactivation System will ONLY work with a special seat designed to
operate with it. It will not work with seats which are not BabySmart™ 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 side front airbag will not deploy only if the 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™ restraint to transport
children, on the front passenger seat until the system has been repaired.
Self-Test BabySmart™ Without Special Child Seat Installed
After turning electronic key in steering lock to position 1 or 2, the indicator lamp located on
center console comes on for approx. 6 seconds.
If the lamp should not come on or is continuously lit, the system is not functioning. You must see an
authorized Mercedes-Benz dealer before using any child seat on the front passenger seat.
Emergency Tensioning Retractor (ETR)
The seat belts for the front 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 steering lock 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 and in rear impacts exceeding a preset security level. 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 ac tivated. The driver and passengers will then be protected by the
fastened seat belts and inertia reel in the usual manner. For seat belt and emergency tensioning
retractor safety guidelines see Safety Guidelines in Index.
Airbags
1. Driver airbag
2. Front passenger airbag
3. Side impact airbag
The most effective occupant restraint system yet developed for use in production vehicles is the seat belt. In some
cases, however, the protective effect of a seat belt can be further enhanced by an airbag. The driver airbag is located
in the steering wheel hub. The passenger airbag is located in the dashboard ahead of the passenger.
The side impact airbags are located in the front doors. In conjunction with wearing the seat belts with emergency
tensioning retractors, the airbags can provide increased protection for the driver and passenger in certain major
frontal (for front airbags) and side impacts (for side impact airbags). The operational readiness of the airbag system is
verified by the indicator lamp "SRS" in the instrument cluster when turning the electronic key in steering lock to
position 1 or 2. If no fault is detected, the lamp will go out after approximately 4 seconds; after the lamp goes out, the
system continues to monitor the components and circuitry of the airbag system and will indicate a malfunction by
coming on again.
The following system components are monitored or undergo a self-check: crash-sensor(s), airbag ignition circuits,
front seat belt buckles, emergency tensioning retractors, seat sensor . Initially, when the electronic key is turned from
steering lock position 0 to positions 1 or 2, malfunctions in the crash-sensor are detected and indicated (the "SRS"
indicator lamp stays on longer than 4 seconds or does not come on). Have the system checked at your authorized
Merzedes-Benz dealer immediately. In the operational mode, after the indicator lamp has gone out following the initial
check, interruptions or short circuits in the airbag ignition circuit and in the driver and passenger seat belt buckle
harnesses, and low voltage in the entire system are detected and indicated.
Warning !
In the event a malfunction of the "SRS" is indicated as outlined above, the "SRS" may not be operational. For
your safety, we strongly recommend that you visit an authorized Mercedes-Benz dealer immediately to have
the system checked; otherwise the "SRS" may not be activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy unexpectedly and unnecessarily which could also result in
injury.
Front Airbags
The driver and passenger front "SRS" airbags are designed to activate only in certain frontal impacts.
The front passenger airbag deploys only if the front passenger seat is occupied and the indicator lamp on the
center console is not illuminated.
Note:
Heavy objects on front passenger seat can cause the passenger front airbag to deploy in a crash.
Side Impact Airbags
The side impact "SRS" airbags are designed to activate only in certain side impacts. Only the side impact airbag on
the impacted side of the vehicle deploys. The side impact airbag for the front passenger deploys only if the front
passenger
seat is occupied. Side impact airbags operate best in conjunction with a properly positioned and fastened seat belt.
Note:
Heavy objects on front passenger seat can cause the side impact airbag to deploy in a crash.
Steering Lock
0 - The electronic key can be withdrawn in this position only. The steering is locked with the electronic key removed
from the steering lock. The electronic key an be removed only with the selector lever in position "P" and the foot off
the brake pedal. After removing the electronic key or with the electronic key in steering lock position 0, the
selector lever is locked in position "P".
1 - Steering is unlocked. (If necessary, move steering wheel slightly to allow the electronic key to be turned clockwise
to position 1.) Most electrical consumers can be operated. For detailed information see respective subjects.
2 - Driving position.
3 - Starting position.
Refer to Index for Starting and turning off the engine.
Warning !
When leaving the vehicle always remove the electronic key from the steering lock, and lock the vehicle.
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.
Important !
If the electronic key is left in the steering lock position 0 for an extended period of time, it can no longer be turned
in the lock. In this case, remove electronic key from steering lock and reinsert.
Notes:
A warning sounds when the driver's door is opened with the electronic key in steering lock position 1 or 0. With the
engine at idle speed, the charging rate of the alternator (output) is limited. It is therefore recommended to turn off
unnecessary electrical consumers while driving in stop-and-go traffic. This precaution helps to avoid draining of the
battery. Unnecessary strain on the battery and charging system may be minimized by turning off the following power
consumers, for example: Heated seats, rear window defroster. In addition, the automatic climate air volume control
should be set to the lowest position. The steering lock can only be unlocked with the vehicle battery properly
connected.
Caution !
To prevent accelerated battery discharge and a possible dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering lock position 0.
