#
Electric consumers
offline!
The consumer battery has insuffi-
cient voltage and can no longer sup-
ply the convenience functions such
as seat ventilation*.
The electrical consumers will come back online
as soon as on-board voltage is sufficient.
Battery/Alternator
Stop vehicle!
The battery was charged with a bat-
tery charger or jump started.
The battery is no longer charging.
Possible causes

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may
be operating with restricted capabil-
ity. Considerably greater brake ped-
al force is required and the stopping
distance is increased.

Have the battery checked at a service sta-
tion.

Stop immediately and check the poly-V-belt.
If it is broken
Do not continue to drive. Notify an autho-
rized Mercedes-Benz Center.
If it is in order

Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.

Service brake
Visit workshop!
There are malfunctions, but the SBC
brake system is operating normally.

Visit an authorized Mercedes-Benz Center as
soon as possible.
Incr.
braking distance
Start engine!
The battery has insufficient voltage
and cannot supply sufficient power
to the SBC brake system.

Start the engine.
The message disappears when sufficient
voltage is available.
Brakes overheated!
Drive carefully!
The brake system is overheated due
to an excessive load on the brakes.

Relieve the load on the brake system.

Drive more smoothly and think ahead to
avoid unnecessary braking.

When driving down steep grades, shift into a
lower gear to use the engine’s braking power
(page 139).

Cautiously continue driving so that the air
stream will cool down the brakes.

343 Technical data
Fuels, coolants, lubricants, etc.
Engine oils
Engine oils are specifically tested for their
suitability in our engines. Therefore, only
use engine oils recommended by
Mercedes-Benz. Information on recom-
mended brands is available in the Factory
Approved Service Products pamphlet, or at
your authorized Mercedes-Benz Center.
Please follow FSS recommendations for
scheduled oil changes. Failure to do so
could result in engine damage not covered
by the Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil.
They may be harmful to the engine opera-
tion.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
er system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil, otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Therefore, the brake fluid must be re-
placed every two years, preferably in the
spring.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.

352 Technical termsCockpit
All instruments, switches, buttons and
indicator/warning lamps in the passen-
ger compartment needed for vehicle
operation and monitoring.
Collapsible tire
An especially compact spare tire that
must be inflated with a provided air
pump before using. It should only be
used to bring the vehicle to the nearest
service station.
COMAND
(Co
ckpit Man
agement and
D
ata System)
Information and operating center for
vehicle sound and communications
systems, including the radio and CD
changer, as well as for other optional
equipment (e.g. telephone).
Control system
The control system is used to call up
vehicle information and to change

messages appear in the multifunction
display. The driver uses the buttons on the multifunction steering wheel to
navigate through the system and to ad-
just settings.
Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.
Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional cruise control.


If a slower moving vehicle is ahead,
Distronic* will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.
DTR
(->Distr
onic*)Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.
ESP

lectronic S
tability P
rogram)
Improves vehicle handling and direc-
tional stability.
ETD
