For cleaning and care of the seat belts, see page 354.
Seat belt nonusage warning system
After starting the engine, a warning sounds a short time 
and the seat belt warning lamp< remains 
illuminated if the driver’s seat belt is not fastened.
Wa r n i n g !
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.
Wa r n i n g !
Failure to wear and properly fasten and position 
your seat belt greatly increases your risk of 
injuries and their likely severity in an accident. 
You and your passengers should always wear seat 
belts.If you are ever in an accident, your injuries can be 
considerably more severe without your seat belt 
properly buckled. Without your seat belt buckled, 
you are much more likely to hit the interior of the 
vehicle or be ejected from it. You can be seriously 
injured or killed.In the same crash, the possibility for injury or 
death is lessened if you are wearing your seat belt.Wa r n i n g !
Never let more people ride in the vehicle than there 
are seat belts available. Be sure everyone riding in 
the vehicle is correctly restrained with a separate 
seat belt.

Special BabySmart
TM compatible child seats, designed

required for use with the BabySmart
TM airbag 
d eactivation  system.  Wit h t he sp ecial child  s eat p rop erly

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 Light Truck Center 
before seating any child on the front passenger seat. See 
page 271 for notes on the ü indicator lamp.
BabySmart

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.

The seat belts for the front seats and outboard 
passenger seats are equipped with emergency 
tensioning retractors. These tensioning retractors are 
located in each seat belt buckle and become 
operationally ready with the 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 
and in rear impacts exceeding a preset severity 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 activated. 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 see 
page 71.Note:
The emergency tensioning retractors for the driver and 
front passenger seats will only deploy if the front seat 
belts are buckled.
The rear center automatic two point seat belt is not 
equipped with an emergency tensioning retractor.

Front airbags
The driver and front passenger front airbags are 
designed to activate only in certain frontal impacts 
exceeding a preset threshold.
The front passenger airbag deploys only if the front 
passenger seat is occupied and the ü indicator lamp 
in the instrument cluster is not illuminated, see 
page 271.
Note:
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 in a crash exceeding the appropriate threshold.Important!
Airbags are designed to activate only in certain 
frontal (front airbags) impacts which exceed preset 
thresholds.
Only during these types of impacts, if of sufficient 
severity to meet the deployment thresholds, will 
they provide their supplemental protection.
The driver and passenger should always wear their 
seat belts, otherwise it is not possible for the airbags 
to provide their intended supplemental protection.
In cases of other frontal impacts, angled impacts, 
roll-overs, other side impacts, rear collisions, or 
other accidents in which the airbags are not 
designed to deploy, the airbags will not be activated. 
The driver and passenger will then be protected by 
the fastened seat belts.
We caution you not to rely on the presence of the 
airbags in order to avoid wearing your seat belt.
