2000-01 ACCESSORIES/SA FETY EQUIPMENT
Mercedes-Benz - Air Bag Restraint Systems
DESCRIPTION & OPERATION
All models are equipped with Supplemental Restraint Syst em (SRS). The main components of SRS are driver-
side air bag module, passenger-side air bag module, si de air bag modules (located in doors), SRS control
module, side air bag sensors, SRS warning light, driver knee bolster, pa ssenger knee bolster, and Emergency
Tensioning Retractor (ETR) seat belt assembly. Additionally, some vehicles may be equipped with head impact
(curtain type) air bags (located ar ound door windows behind door frame trims).
Both SRS and ETR are electronically activated by a single control module. There are 2 thresholds which must
be exceeded to trigger an ETR acti on, air bag deployment, or both. If a moderately severe frontal collision
occurs exceeding first triggering thre shold where protection from safety belt is sufficient, only Emergency
Tensioning Retractor (ETR) is activated if safety belt is buckled. If a moderately severe frontal collision occurs
exceeding first triggering threshold where protection from safety belt is sufficient, but safety belt is not buckled,
air bag is deployed and ETR is not activated.
If a severe frontal collision occurs exceeding second triggering threshold where protection from safety belt is
insufficient, air bag is deploye d. ETR is activated if safety belt is buckled. If safety belt is not buckled, ETR is
not activated when second triggering threshold is reached. Passenger air bag will deploy even if passenger seat
is not occupied when a triggering thre shold is exceeded. If during a severe frontal collision the power supply is
interrupted, the driver and passenger air bag can still be deployed, but ETR cannot be activated.
The side air bag on the driver-side deploys whenever th e driver-side air bag module is deployed and when there
is a substantial side impact crash. The air bag on the pa ssenger-side will activate only when a sensor (Occupied
Seat Recognition Sensor) in the passenger seat sends a si gnal to the SRS control module that the passenger-side
seat is occupied. During a collision, the side air bag will then deploy.
COMPONENT LOCATIONS NOTE: The following 2000 in
formation represents the latest information available at
time of publication and m ay be useful in diagnosing 2001 vehicles. 2001 wiring
diagrams have been included at the end of this article.
WARNING: Accidental air bag deployment is pos sible. Personal injury may result.
Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS

before working on ai r bag system or related components.

Checklist before off-road driving •Tires: Check the tread depth and maintain specified
tire pressure (see tire pressure label inside the fuel
filler flap). Check tires for possible damage and
remove foreign objects. The valve caps must be
mounted.
•Rims: Dented or bent rims can cause tire pressure
loss and damage the tire beads. For this reason
change rims before driving off-road.
• Vehicle tool kit: Check if the vehicle jack is
functional. In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small plank (to put
under the vehicle jack on sandy soil) with you. Driving in steep terrain
Slope angle:
1 26° (ML 320 and ML 430)
23 ° (ML 55 AMG)
2 26° (ML 320 and ML 430)
21 ° (ML 55 AMG)
Switch to LOW RANGE mode before starting to drive up
or down steep inclines, see page 209.
Maximum vehicle climbing ability is a 60% grade.

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase. Tire replacement
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 288.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torq ue of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 288.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

Rotating wheels
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement. Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
dam age to t he tire bead s. For this reason, ch eck rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
page 250.
