58 Safety and SecurityOccupant safety
Adjust the driver seat as far as possible 
rearward, still permitting proper opera-
tion of vehicle controls. The distance 
from the center of the driver’s breast-
bone to the center of the airbag cover on 
the steering wheel must be at least ten 
inches (25 cm) or more. You should be 
able to accomplish this by a combina-
tion of adjustments to the seat and 
steering wheel. If you have any prob-
lems, please see your authorized 
Mercedes-Benz Center.
Do not lean with your head or chest 
close to the steering wheel or dash-
board.
Keep hands on the outside of steering 
wheel rim. Placing hands and arms in-
side the rim can increase the risk and 
potential severity of hand/arm injury 
when driver front airbag inflates.
Adjust the front passenger seat as far as 
possible rearward from the dashboard 
when the seat is occupied.
Occupants, especially children, should 
never lean their heads in the area of the 
door where the side airbag inflates. This 
could result in serious injuries or death 
should the airbag be triggered. Always 
sit upright, properly use the seat belts 
and appropriate size infant or child re-
straint system.
Children 12 years old and under must 
never ride in the front seat, except in a 
Mercedes-Benz authorized 
BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM 
system installed in the vehicle to deacti-
vate the passenger front airbag when it 
is properly installed. Otherwise they will 
be struck by the airbag when it inflates 
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible 
to make the buyer aware of these points. Be 
sure to give the buyer this Operator’s Manu-
al.
Warning!
G
Accident research shows that the safest 
place for children in an automobile is in the 
rear seat. Should you choose to place a child 
12 years old or under in the front passenger 
seat of your vehicle, you must properly use 
a BabySmart
TM child restraint which will 
turn off the passenger front airbag. 
BabySmart
TM will not, however, turn off any 
side impact airbag.
It should be noted that with respect to both 
front and rear side impact airbags there is a 
possibility for a side airbag related injury if 
occupants, especially children, are not prop-
erly seated or restrained when next to a side 
airbag which needs to deploy rapidly in a 
side impact in order to do its job.
To help avoid the possibility of injury, please 
follow these guidelines: 
(1) Occupants, especially children, should 
never place their bodies or lean their 
heads in the area of the door where the 
side airbag inflates. This could

Information on the windshield wipers is 
found in the “Getting started” section 
(page 47).
A rain sensor automatically controls the 
windshield wipers depending on how wet 
the windshield is.
Switch on ignition.
Set wiper switch to position I 
(page 47).
After the initial wipe, pauses between 
wipes are automatically controlled by the 
rain sensor which monitors the wetness of 
the windshield.

the vehicle is at a standstill and a front 
door is opened.
!To prevent the windshield wipers from 
being damaged, do not leave the wiper 
switch in intermittent setting when tak-
ing the vehicle to an automatic car 
wash or when cleaning the windshield.
The switch should not be left in inter-
mittent setting as the wipers will wipe 
the windshield once every time the en-
gine is started. Dust that accumulates 
on the windshield might scratch the 
glass when wiping occurs on a dry 
windshield.iIf intermittent wiping is on and you turn 
the SmartKey in the steering lock from 
position 1 to position 2 (
page 31) 
and keep the SmartKey in that position 
longer than 2 seconds, the wipe inter-
val will be set to approximately 5 sec-

Ventilation of the storage compartment 
below the front armrest is possible only 
when the climate control system is on. The 
air volume depends on the setting of the 
air distribution control, the air volume con-
trol, and the air vents in the dashboard.
