Keys Doors
Central Locking System
The entire vehicle may be locked or unlocked with the central locking sys tem:
Using the master key, supplemen tary key, or by pushing down or pulling up the interior door lock buttons at the front doors.
From the trunk using the master key only.
The central locking system allows you to lock or unlock all doors, trunk lid and fuel filler flap simultaneously.
Doors When you lock the car, all door lock
buttons should move down. If any one stays up, the respective door was not properly closed. You should then unlock the car, open and re-close this door, and lock the car again.
Note: The central locking system can be
engaged from the driver-side door lock button, provided the door is completely closed. It can also be engaged from the passenger-side if the ignition key is removed, or engaged in the lock without being turned (key in position 0 ).
If the car has been locked from the outside with the master key, the anti theft alarm will come on if a door is opened from the inside.
Trunk To unlock the trunk with the central
locking system, turn the master key in
the trunk lock completely to the left
and let it return to the normal posi
tion. Push in trunk lock button and
open the trunk. To lock the trunk, turn
the master key completely to the right
and let it return to the normal posi tion.
The trunk can remain locked while the
central locking system is unlocked (e.g. while driving or when leaving the car in a situation where it must be driven using the supplementary key but you wish the trunk to remain locked at parking lots, workshops, etc.). Turn the master key completely to the right and pull it out in that posi tion. Now the trunk can only be unlocked with the master key by turn ing it back to the left.
Important!
Contrary to prior model year vehicles,
if the trunk is unlocked with the cen tral locking system engaged, the doors and fuel filler flap will also be
unlocked. After closing the trqnk, the
central locking system must again be
engaged using the key!
Note:
If the fuel filler flap cannot be opened,
refer to Unlocking the Fuel Filler
Flap (page 83).
Keys Doors
Anti-Theft Alarm System
The anti-theft alarm can be armed or disarmed with the master key (identi fied by red dot) by locking or unlock
ing either front door or the trunk. Operation
Once the alarm system has been armed, the vehicle lamps will flash and the horn will sound intermittently when an unauthorized person tries to:
open a door
open the trunk
remove the radio
switch on or bridge the steering
lock
step on the brake pedal
raise the vehicle, i.e. towing away.
The alarm will last approximately
150 seconds in the form of blinking exterior lamps. At the same time an additional horn will sound intermit tently for 60 seconds, and repeat for another 60 seconds after a 30 second pause.
The alarm will stay on even if the arm ing element (a door, for example) is immediately closed.
To avoid setting off the alarm uninten tionally, do not arm the alarm system in the following situations; e.g.: Auto ferry, auto train, when hitching/ unhitching a trailer, or heavy loading/ unloading. For this purpose use the supplementary key and not the mas ter key for locking the vehicle.
Special Function
To activate the anti-theft alarm from the trunk, turn the master key in the trunk lock completely to the right and pull it out in this position.
If you want the alarm system to be armed at the trunk only, turn the mas ter key in the trunk lock completely to the right and pull it out in that posi tion. Then disarm the rest of the vehi cle by unlocking either front door with the master key. You can now lock or unlock the doors and filler flap, as well as start the engine, in the usual man ner using the supplementary key.
Do not give the master key to an unauthorized person. We recommend that you carry the flat key safely with you (e.g. in your wallet) so that it is always handy, if needed. This key has the same function as the master key.

Seats
insure adequate control, reach, oper
ation, and comfort. The head restraint
should also be adjusted for proper
height so that when the cushion is tipped completely forward, it should form a cradle behind the seat
occupants head.
Both the inside and outside rear view
mirrors should then be adjusted for adequate rearward vision. Fasten seat
belts. Children under the age of six or under the weight of 23 kg/50 lb should be seated in the back seat with an approved restraint system
properly secured. All seat, head restraint and rear view
mirror adjustments as well as fasten
ing of seat belts should only be accomplished before the vehicle is put into motion.
Orthopedic Seat Backrest
Some models may be equipped with orthopedic seats. These seats have an inflatable air cushion built into the backrest to provide additional lumbar support. The amount of cushion height and curvature may be adjusted after turning the key in steering lock to position 2 .
The inflation pressure of the air cushion may be continuously varied between position 0 = without pressure, and position 4 = maxi mum pressure, by changing the pressure regulator (1) setting.
In addition, the cushion height may be changed to five different settings between position A = lowest setting, and E = highest setting, by
varying the height regulator (2)
adjustment. If a driving trip is temporarily inter
rupted, the last cushion setting is retained in memory, and automatically adjusts the cushion to this setting
when the trip is continued.
19
Arm Rest (Front Seats) The arm rest engages in 3 positions.
Position 1 = arm rest folded up. Position 2 = for normally inclined
seat back. Position 3 = for extremely inclined
seat back. For downward adjustment of the arm
rest, depress release button 4.
Warning!
The arm rest does not suffice as a child restraint system. In case of a frontal collision a child can be
catapulted forward over the locked arm rest.
Arm Rest (Rear Seat) An arm rest is provided in the rear
seat which can be pulled out with the
loop. For the removal of the rear seat
cushion see "Practical Hints .

Supplemental Restraint System
Unfastening:
Push in the red button (3) in the belt buckle.
The retractor should completely rewind the belt and latch plate (1).
Operation:
The inertia reel stops the belt from
unwinding during sudden vehicle stops or when quickly pulling on the belt.
The locking function of the reel may
be checked by quickly pulling out the belt.
To shorten the belt, pull belt end with the latch plate engaged. To lengthen the belt, turn the latch plate so that it is at a little more than 90° to the belt and pull before fastening the belt.
To disengage the belt, push red
button (3) in the buckle.
Lap belt in rear passenger compart ment:
Pull belt with latch plate (1) across the lap, and push latch plate into buckle (2) until it clicks. The belt must not be twisted and must be tight.
23
Supplemental Restraint System
The emergency tensioning retractors
are designed to activate only during severe frontal impacts. They tighten the belts in such a way that they fit more snugly against the body restrict ing as much as possible its forward movement.
In cases of less severe frontal impacts, such as roll-overs, side or rear collisions, or other accidents without severe frontal forces, the emergency tensioning retractors will
not be activated. The driver and pas
sengers will then be protected by the fastened seat belts and inertia reel in the usual manner.
Warning!
Rear seat passengers should always
wear seat belts for their own pro
tection and to avoid endangering the
driver and front passenger with their
unrestricted forward movement.
No seat belt can be used for more than one person. Children under the age of six or under the weight of 23 kg/50 lb should be seated in the
back seat with an approved restraint
system properly secured.
Child restraint systems recom
mended by us can be fastened to the
existing seat belts. Any authorized
MERCEDES-BENZ dealer will gladly
advise you on this subject.
For cleaning and care of the seat
belts, see page 64.
For seat belt and emergency tension
ing retractor safety rules, see
page 26.
24
Driver Airbag
If your vehicle is additionally equipped with a driver airbag, this can be recognized by the letters SRS stamped into the steering wheel hub pad and by the indicator lamp SRS
(Supplemental Restraint System) in
the instrument cluster.
The airbag (1) is located in the steer ing wheel hub and, in conjunction with wearing the seat belts with ten sioning retractors (2), provides increased protection for the driver.
The operational readiness of the sup
plemental restraint system (airbag and emergency tensioning retractor) is verified by the indicator lamp
Supplemental Restraint System
SRS" (3) in the instrument cluster. With the key in steering lock position 1” or 2 , the indicator lamp comes on for about 10 seconds then goes out. If it doesnt come on, doesnt go out, flickers on and off, or comes on while driving, the system is malfunc tioning.
This will not cause the supplemental
restraint system to be activated. How ever, we strongly recommend that you visit an authorized MERCEDES-
BENZ dealer immediately to have the system checked; otherwise the
SRS may not be activated in a sev ere frontal accident.
The airbag is designed to activate only in severe frontal impacts (see
illustration on page 24). Only during these types of impacts will it provide
its supplemental protection. The
driver should always wear the seat
belt, otherwise it is not possible for the airbag to provide its intended pro tection.
Supplemental Restraint System
In cases of less severe frontal impacts, such as roll-overs, side or rear collisions, or other accidents without severe frontal forces, the airbag will not be activated. The driver and other passengers will then be
protected by the fastened seat belts.
The activation of the SRS temporar
ily releases a small amount of dust
from the driver airbag and all of the
seat belt emergency tensioning retractors. This dust, however, is neither injurious to your health, nor does it indicate a fire in the vehicle.
The service life of the airbag extends to the date indicated on the glove compartment sticker. To provide continued reliability after that date, it should be inspected by an authorized
MERCEDES-BENZ dealer at that
time.
Safety Guidelines for the Supplemental Restraint System Seat Belts, Emergency Tensioning
Retractor and Airbag
Damaged 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 MERCEDES-BENZ.
Do not pass belts over sharp edges. Do not make any modification that
could change the effectiveness of the
belts.
An airbag or tensioning retractor that was activated must be replaced.
No modifications of any kind may be made to any components or wiring of
the SRS . This includes the
installation of additional trim material, badges, etc. over the steering wheel hub and installation of additional electrical/electronic equipment on or near SRS components and wiring.
Improper work on the system, includ ing incorrect installation and removal, can lead to possible injury through an uncontrolled activation of the SRS . In addition, through improper work there is the risk of rendering the SRS inoperative. Work on the "SRS must therefore only be performed by an authorized MERCEDES-BENZ dealer.
When scrapping the airbag unit or tensioning retractor, it is mandatory to follow our safety instructions. These instructions are available at every authorized MERCEDES-BENZ dealer.
When you sell the vehicle we strongly
urge you to give notice to the subsequent owner if it is equipped
with an SRS" by alerting him to the
applicable section in the Owners Manual.

Steering Lock
0 Steering is locked when the key is
withdrawn and the steering lock is engaged. The key can be with drawn only in zero position.
Note: Do not remove key from steering
lock while the vehicle is in motion as this will cause the engagement of the steering lock thus rendering
the vehicle inoperable.
1 Steering is unlocked.
(If necessary, move steering wheel slightly to turn the key clockwise to position 1” .)
2 Preglowing and driving position. 3 Starting position.
For starting and turning off the engine, refer to page 50.
Notes: The following items can be operated
with the key in steering lock position 1 :
Wiper, windshield washer, headlamp flasher, lighter, glove compartment lamp, radio, seat heater for front seats.
A warning buzzer sounds when the key has been left in steering lock positions 1 or "0 and the drivers door is opened.
With the engine at idle speed, the charging rate of the alternator (out put) is limited.
It is therefore recommended to turn
off unnecessary electrical consumers while driving in stop and go traffic. This precaution helps to avoid drain
ing the battery.
An effective measure to preserve
battery power is to turn off the
following consumers:
Seat heater, heated rear window.
