281 Practical hints
Jump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a more powerful battery could
damage the vehicle's electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.


Use only jumper cables with sufficient-
cross-section and insulated terminal
clamps.


Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when the engine is
started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If engine does not run after several un-
successful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Light Truck Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and
may present a fire risk.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.

282 Practical hintsJump startingThe battery is located on the right side of
the engine compartment.
Make sure the two vehicles do not
touch.

Turn off all electrical consumers.

Apply parking brake.

Shift gear selector lever to positionP.

Open the hood.

Connect positive terminals1 and4
of the batteries with the jumper cable.
Clamp cable to positive terminal4 of
charged battery first.1Positive terminal of discharged battery
2Negative terminal of discharged
battery
3Negative terminal of charged battery
4Positive terminal of charged battery

Start engine of the vehicle with the
charged battery and run at idle speed.

Connect negative terminals2 and3
of the batteries with the jumper cable.
Clamp cable to negative terminal3 of
charged battery first.

Start the engine of the disabled vehi-
cle.
Now you can turn on the electrical
consumers. Do not turn on the lights under
any circumstances.

Remove the jumper cables first from
the negative terminals2 and3 and
then from positive terminals1
and4.
You can now turn on the lights.

Have the battery checked at the
nearest authorized Mercedes-Benz
Light Truck Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 223).
!Never invert the terminal connections.
!Do not tow-start the vehicle.

Title forward/backward
If the "joystick " is pressed to right the next CD title is skipped. Pressing to left within the first 10 s of
playback causes jumping to the previous title, otherwise to the beginning of the title presently being
played. If the" joystick " is held to left or right the changer jumps from one title to the next within short
time intervals without playing them.
Fast forward/rewind (music search)
If the "joystick " is pressed up or down the titles are played quickly. This allows specific parts of a title to
be played or skipped. When the start or end of the CD is reached the search is interrupted.
Title repetition and random playback
Random playback can be activated/deactivated with the multifunction " RDM " key. When activated this
function is indicated on the display and random playback can then be selected. The random playback
feature affects only the CD presently being played back. Title repetition can be activated/ deactivated
with the multifunction " RPT key. The title presently selected is repeated until the function is deactivated.
The random playback and title repetition remain active, even when the radio and navigation module
(A2/56) is switched off and switched back on again. Actuating these two functions simultaneously is not
possible.
Pause
The multifunction key" II "(Pause ) interrupts the title presently being played. Pressing again continues
playback.
Direct title selection
Pressing the " *" button followed by entry of the desired title via the number block allows direct selection
of the title.
Multifunction key Time
By pressing the multifunction key" Time " it is possible to change between 2 different display modes:
Display of title number and previous playback time of title (standard setting)
Number of titles and entire playback time of CD ("Time appears on display).
CD title assignment, function
Each CD has a permanently stored, so-called T able of C ontents (TOC ) entry. The radio and navigation
module (A2/56) recognizes the CD clearly on the basis of this entry and can automatically designate it (even
when the CD is then inserted into another CD ma
gazine) after the title has been assigned once by the user.

The laser-optical device scans the non-labeled side of the rotating CDwithout making contact and converts the
digital optical signals into electrical signals. Small interruptions in the data flow of the laser optics caused by
scratches or contamination on the audio CD are compensated by the D/A converter supplementing the missing
values .
The electrical signals are then decoded in the CD player with changer (in trunk) (A2/6) and transmitted via
the digital data bus ( D2B ) to the radio and navigation module (A2/56) via the audio signal processing or
when the sound amplifier (A2/13) (code 810) is installed to the loudspeakers.
Jumps and interruptions during playback
On bad roads or in the event of heavy vibrations , jumps and interruptions can occur during playback. In
such cases do not start CD mode until better road conditions are present.
In the event of wet weather conditions and strong deviations in the ambient temperatures moisture can collect in
the CD player housing (condensation formation). This could also lead to malfunctions in the playback. In such
cases provide for sufficient ventilation of the CD player and the trunk.

Fig. 106: Identifying Electromagnetic Clutch (A9K1) Components
Function
In order to start operating the refrigerant compressor, the push-button control module (N19, N22) actuates the
electromagnetic clutch (A9k1) and the solenoid (5) is supplied with electrical current. The magnetic force
attracts the pressure plate (6) against the rubber insert (7) and holds it securely. This creates the frictional
connection between the automotive engine and the refrigerant compressor. If the solenoid (5) is de-energized,
then the pressure plate (6) is pressed back by the rubber insert (7) into its rest position and the frictional
connection is interrupted.
Safety shutoff of the refrigerant compressor
To prevent a mechanical defect in the refrigerant compressor from causing the poly V-belt to jump loose, the
electromagnetic clutch releases itself automatically. With a mechanical defect, the refrigerant compressor
rotates more sluggishly or even locks completely. The heat generated at the friction surface causes the melting
fuse (2) in the solenoid (5) to melt. The current supply to the solenoid (5) is interrupted and the frictional
connection is released.
ELECTROMAGNETIC CLUTCH, LOCATION - GF83.55-P-2101-02GH
The electromagnetic clutch (A9k1) is located on the drive shaft of the refrigerant compressor (A9) at the front
left in the en
gine compartment.
