Mirrors
Adjust the interior and exterior rear view 
mirrors before driving so that you have a 
good view of the road and traffic condi-
tions.
Interior rear view mirror

mirror.
For more information, see “Rear view mir-
rors” (
page 185).
Exterior rear view mirrorsThe buttons are located on the lower part 
of the center console.
1Driver’s side exterior rear view mirror 
button
2Passenger-side exterior rear view mir-
ror button
3Adjustment button
Switch on the ignition (page 40).
Press button1 or button2 to select 
the desired exterior rear view mirror.

left, or right according to the desired 
setting.For more information, see “Good visibility” 
(
page 185).
Warning!G
Exercise care when using the 
passenger-side exterior rear view mirror. 
The mirror surface is convex (outwardly 
curved surface for a wider field of view). Ob-
jects in mirror are closer than they appear. 
Check your interior rear view mirror or 
glance over your shoulder before changing 
lanes.
!If an exterior rear view mirror was forcibly 
pushed forward (hit from the rear) or forcibly 
pushed rearward (hit from the front), reposition 
it by applying firm pressure until it snaps into 
place. The mirror housing is then properly posi-
tioned and you can adjust the mirror in the usual 
manner.
iAt low ambient temperatures, the exterior 
rear view mirrors will be heated automatically.
iThe memory function (page 129) lets you 
store the setting for the exterior rear view 
mirrors together with the settings for the 
steering wheel and the driver’s seat position.

74 Safety and Security
Occupant safety
The passenger air bag will only be de-
ployed if: 
the system, based on OCS weight 
sensor readings, senses that the 
passenger seat is occupied
the5/ indicator lamp in the 
center console is not lit (
page 78)
the impact exceeds a preset deploy-
ment threshold
Knee bag
The knee bag is located on the driver’s side 
lower instrument panel. It is designed to 
operate together with the driver front air 
bag in certain frontal impacts exceeding a 
preset threshold. The knee bag operates 
best in conjunction with a properly posi-
tioned and fastened seat belt.Head-thorax air bags
1Head-thorax air bag
The head-thorax air bags are deployed: 
in side impacts exceeding a preset 
deployment threshold
on the impacted side of the vehicle
independently of the front air bags
The head-thorax air bags are not deployed 
in impacts which do not exceed the sys-
tem’s deployment threshold.
Occupant Classification System
The O
ccupant Classification System (OCS) 
automatically turns the passenger front air 
bag on or off based on the classified occu-
pant weight category determined by 
weight sensor readings from the 
passenger seat.
Occupants must sit properly belted in a 
position that is as upright as possible with 
their back against the seat backrest and 
feet on the floor to be correctly classified. 
If the occupant’s weight is transferred to 
another object in the vehicle (e.g. by 
leaning on armrests), the OCS may not be 
able to properly approximate the 
occupant’s weight category. 
iThe system does not deactivate the 
head-thorax air bag and the emergency tension-
ing device.

78 Safety and Security
Occupant safety
The 5/indicator lamp is located in 
the upper part of the center console, be-
tween the center air vents.
1Passenger front air bag off indicator 
lamp
The 5/indicator lamp1 will be 
illuminated, except with the SmartKey 
removed or in starter switch position0.Self-test Occupant Classification 
System
After turning the SmartKey in the starter 
switch to position1 or2 or pressing the 
KEYLESS-GO* start/stop button once or 
twice, the 5/ indicator lamp 
located in the upper part of the center 
console, between the center air vents 
illuminates. If an adult occupant is properly 
sitting on the passenger seat and the 
system senses the occupant as being an 
adult, the5/ indicator lamp will 
illuminate and go out after 
approximately 6 seconds. 
If the seat is not occupied and the system 
senses the passenger seat as being empty, 
the 5/ indicator lamp will 
illuminate and not go out. 
Warning!G
If the 1indicator lamp and the 
5/indicator lamp are lit at the same 
time, there is a malfunction in the Occupant 
Classification System. The passenger front 
air bag will be deactivated in this case. Have 
the system checked as soon as possible by 
qualified technicians. Contact an authorized 
Mercedes-Benz Center.
Only have the seat repaired or replaced by 
an authorized Mercedes-Benz Center.
In order to ensure proper operation of the 
air bag system and OCS:
Sit properly belted in a position that is 
as upright as possible with your back 
against the seat backrest.
While seated, an occupant should not 
position him/herself in such a way as to 
cause the occupant’s weight to be lifted 
from the seat bottom as this may result 
in the OCS to be unable to correctly 
approximate the occupant’s weight 
category.
Read and observe all warnings in this 
chapter.
