222 OperationEngine compartment
Screw filler cap2 back on filler neck.
More information on engine oil can be
found in the “Technical data” section
(
page 300) and (
page 301).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Light
Truck Center check the automatic trans-
mission.Coolant
The engine coolant is a mixture of water
and anticorrosion / antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
Warning!
G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if engine temperature is above
194°F (90°C). Allow engine to cool
down before removing cap. The coolant
reservoir contains hot fluid and is under
pressure.


Using a rag, slowly open the cap approx-
imately ½ turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.


313 Technical terms
GVWR
(G
ross V
ehicle W
eight R
ating)
This is the maximum permissible vehi-
cle weight. It is indicated on certifica-
tion label located on the driver’s door
pillar.
Instrument cluster
The displays and indicator / warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
engine temperature and fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.Line of fall
The direct line that an object moves
downhill when influenced by the force
of gravity alone.
Lock button
Button on the door which indicates
whether the door is locked or un-
locked. Pushing the lock button down
on an individual door from inside will
lock that door.
MCS
(M
odular C
ontrol S
ystem)
Information and operating center for
vehicle sound and communications
systems, including the radio and the ra-
dio and navigation system, as well as
for other optional equipment (CD
changer, telephone, etc.).Memory function*
Used to store three individual seat,
steering wheel and mirror positions.
MON
(M
otor O
ctane N
umber)
The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline's
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
Multifunction display
A display field in the instrument cluster
used to present information provided
by the control system.
Parktronic system* (Parking assist)
System which uses visual and acoustic
signals to assist the driver during park-
ing maneuvers.

315 Technical terms
Tele Aid System*
(T
elematic A
larm I
dentification on
D
emand)
The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.
Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.
Transfer case
Speed of rotation / torque converter
that works together with the ->auto-
matic transmission. In the LOW mode
off-road position, the transfer case de-
creases the output rotational speed of
the ->automatic transmission by ap-
proximately half. This results in a corre-
sponding increase of torque on the
drive axles.
The vehicle then has nearly double the
driving force but drives only approxi-
mately half as fast.TWR
(T
ongue W
eight R
ating)
The TWR is the maximum permissible
weight on the trailer tongue.
VIN
(V
ehicle I
dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system*
Voice control system for car phones,
portable cell phones and audio sys-
tems (radio, CD, etc.).

Notes on installation of GPS antenna
The GPS antenna should be installed only in a vertical position with a maximum deviation of 10° from
horizontal.
The GPS antenna should always have a free view of the sky. Thermal insulated windows can significantly
reduce the function of the GPS antenna.
When installing the GPS antenna, always ensure that the arched surface points away from the vehicle.
Changing the installation location inside of the vehicle after the system is put into operation has no effect on the
GPS reception.
NOTES ON RADIO CONNECTOR PIN ASSIGNMENT - AH82.61-P-0001-05A
Model 163
The pin assignment in the radio connector has been changed on vehicles as of 07.99 (model year 2000)
Fig. 1: Identifying Radio Connector Pin Assignment

Check pin assignment
If the pin assignment is the same as listed in the table above, it is not necessary to install the adapter
wiring harness and CAN bus adapter when installing the Audio 30 APS navigation system.
NOTES ON TELEPHONE OPERATION WITH AUDIO 30 APS NAVIGATION SYSTEM - AH82.61-P-0001-06A
Models 129, 163, 168, 170, 202, 208, 210
Vehicles with telephone code 316 or 317 can be retrofitted with an Audio 30 APS navigation system.
Ensure that the Audio 30 APS navigation system is a unit with part number A 208 820.....Older units with part
number A 168 820 .. .. are not capable of assuming the master function in the D2B- ring.

The Audio 30 APS does not have a number pad. For this reason, it is not possible to control the telephone over
the radio (see operating instructions).
On vehicles (as of approx. 07.99) with multifunction steering wheel (telephone control with keys on steering
wheel) this function is then also possible with the Audio 30 APS navigation system.

Customer information, installation position for GPS antenna
There are two different installation locations for the GSP antenna:
1. Standard GPS antenna from DaimlerChrysler on roof or trunk lid. This version offers the best reception
and is therefore preferable.
2. Use of magnetic antenna in vehicle passenger compartment. This version is part of the kit from the
Becker company and installation is described in Becker installation instructions.
Notes on installation of Becker GPS antenna
The GPS antenna can only be installed horizontally with a maximum deviation of 10° from horizontal.
The GPS antenna should always have an unobstructed view of the sky. Tinted windows can reduce the function
of the GPS antenna considerably.
When installing the GPS antenna always ensure that the arched surface of the antenna points upwards.

Routing
The inserts (5) of the fiber optic cable modules may only be routed as in production. The fiber optic cable
modules must always be pr ovided with a protective cap when routing. For every vehicle model, the sequence of
components in the D2B ring is specifically predetermi ned. The components are connected by fiber optic cable
modules. They are secured to a wiring ha rness with an orange-colored casing.
Fig. 4: Identifying Fiber Optic Cable Modules Insert

Danger of breaking! Do not kink fiber optic cable, route over sharp edges or be nd in radii smaller than 25
mm. Tensile forces on inserts must not exceed 65 N.
The fiber optic cable must not be exposed to temperat ures greater than 85°C or lower than -40°C. Do not
squeeze fiber optic cable, in other words do not compress with clamps or cable ties.
Connection between the devices
The Digital Data Bus ring (D2B) connects the new ra dio generation and COMAND (monitor) to the CD
changer (CDC) (USA preinstallati on), telephone and portable CTEL. The sound amplifier remains wired as
COMAND (monitor) to the CD changer (CDC) (USA preinstallation), telephone and portable CTEL. The sound
amplifier remains wired as befo re with Models 129, 170, 202, 208 and 210. The radio and COMAND as head
unit (HU) performs the master function and also forms the interface to the Control Area Network bus Class B
(interior) (CAN-B) (for vehicles wi th multifunction steering wheel).
