approximately 4 seconds or if it comes on thereafter, a 
malfunction in the system has been detected.
The following system components are monitored or 
undergo a selfcheck: crash-sensor(s), airbag ignition 
circuits, seat belt buckles, emergency tensioning 
retractors, seat sensor.
Initially, when the 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). 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.Have the system checked at your authorized 
Mercedes-Benz Center immediately.
Wa r n i n g !
In the event a malfu nction of th e “SRS” is indic ated 
as outlined above, the “SRS” may not be 
operational. For your safety, we strongly 
recommend that you visit an authorized 
Mercedes-Benz Center 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 unnecessary which could also 
result in injury.

To reduce the risk of injury when the front airbags 
inflate, it is very important for the driver and front 
passenger to always be in a properly seated 
position and to wear your seat belt.
For maximum protection in the event of a collision 
always be in normal seated position w ith  your back 
against the backrest. Fasten your seat belt and 
ensure that it is properly positioned on your body.For unobstructive inflation of door side impact 
airbags, keep door pocket lids closed.Since the airbag inflates with considerable speed 
and force, a proper seating and hands on steering 
wheel position will help to keep you at a safe 
distance from the airbag. 
Occupants who are unbelted, out of position or too 
close to the airbag can be seriously injured by an 
airbag as it inflates with great force in the blink of 
an eye:• Sit properly belted in an upright position with 
your back against the backrest.
• Adjust the driver seat as far as possible 
rearward, still permitting proper operation of 
vehicle controls. Adjust the driver seat as far 
as possible rearward, still permitting proper 
operation of vehicle controls. The distance 
from the center of the driver’s breastbone 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 combination of adjustments to the seat and 
steering wheel. If you have any problems, 
please see your authorized Mercedes-Benz 
Center.• Do not lean wi th you r head or chest close to th e 
steering wheel or dashboard.• Keep hands on the outside of steering wheel 
rim. Placing hands and arms inside the rim 
can increase the risk and potential severity of 
hand/arm injury when the driver front airbag 
inflates.• Do not lean against doors.

Safety guidelines for the seat belt, emergency 
tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly 
stressed in an accident must be replaced and 
their anchoring points must also be checked. 
Use only belts installed or supplied by an 
authorized Mercedes-Benz Center.• Do not pass belts over sharp edges.• Do not make any modification that could 
change the effectiveness of the belts.• Airbags and ETR’s are designed to function on 
a one-time-only basis. An airbag or emergency 
tensioning retractor (ETR) that was activated 
must be replaced.
• No modifications of any kind may be made to 
any components or wiring of the “SRS”. This 
includes changing or removing any component 
or part of the “SRS”, the installation of 
additional trim material, badges etc. over the 
steering wheel hub, passenger airbag cover, or 
door trim panels, and installation of additional 
electrical/electronic equipment on or near 
“SRS” components and wiring. Keep area 
between airbags and occupants free of objects 
(e.g. packages, purses, umbrellas, etc.).• An airbag system component within the 
steering wheel gets hot after the airbag has 
inflated. Do not touch.• Improper work on the system, including 
incorrect installation and removal, can lead to 
possible injury through an unintended 
activation of the “SRS”.• 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.

Adju st in g steerin g c olu mn
Turn key in steering lock to position 1 or 2 (with either 
door open, the steering column can be operated with the 
key removed or in steering lock position 0).
To extend or retract:
Move switch (1) in desired direction.
To raise or lower:
Move switch (1) in desired direction.Storing steering column position in memory
The steering column position is stored in memory 
together with the seat/heat restraint/exterior rear view 
mirror position and can be recalled when necessary, 
see memory recalling on page 46.
Wa r n i n g !
Do not adjust the steering wheel while driving. 
Adjusting the steering wheel while driving, or 
driving without the telescoping adjustment locked 
could cause the driver to lose control of the vehicle.

Manually adjust the mirror.
Use your inside mirror to determine the size and 
distance of objects seen in the passenger side convex 
mirror.
Antiglare night position
With the key in steering lock position 2, the mirror 
reflection brightness responds to changes in light 
sensitivity.
With gear selector lever in position “R”, or with the 
interior lamp switched on, the mirror brightness does 
not respond to changes in light sensitivity.Note:
The automatic antiglare function does not react, if 
incoming light is not aimed directly at sensors in the 
mirror.
Wa r n i n g !
In the case of an accident liquid electrolyte may 
escape the mirror housing when the mirror glass 
breaks.Electrolyte has an irritating effect. Do not allow the 
liquid come into contact with eyes, skin, clothing, 
or respiratory system. In cases it does, imm edi ately 
flush affected area with water, and seek medical 
help if necessary.

First select the mirror to be adjusted - turn switch:
1Left mirror
2Right mirror
To adjust, toggle the switch forward, backward or to 
either side.With the key in steering lock position 2, the driver’s 
side mirror reflection brightness responds to changes in 
light sensitivity.
With gear selector lever in position “R”, or with the

brightness does not respond to changes in light 
sensitivity.
Notes:
The exterior mirrors have electrically heated glass. The 
heater switches on automatically, depending on outside 
temperature.
If the mirror housing is forcibly pivoted from its normal 
position, it must be repositioned by applying firm 
pressure until it snaps into place.

Wa r n i n g !
Exercise care when using the passenger-side 
mirror. The passenger-side exterior mirror is 
convex (outwardly curved surface for a wider field 
of view). Objects in mirror are closer than they 
appear. Check your inside rear view mirror or 
glance over your shoulder before changing lanes.
