Vehicle data recording
Vehicle data recording
Information regarding electronic recording devices
(Including notice pursuant to California Code § 9951)
Please note that your vehicle is equipped with devices that can record vehicle systems data and, if equipped with the Tele Aid system,
may transmit some data in certain accidents.
This information helps, for example, to diagnose vehicle systems after a collision and to continuously improve vehicle safety.
DaimlerChrysler may access the information and share it with others

for safety research or vehicle diagnosis purposes


with the consent of the vehicle owner or lessee


in response to an official request by law enforcement or other government agency


for use in dispute resolution involving DaimlerChrysler, its affiliates or sales / service organization and / or


as otherwise required or permitted by law.
Please check the Tele Aid subscription service agreement for details regarding the information that may be recorded or transmitted
via that system.

223 Operation
Engine compartment
Closing
Let the hood drop from a height of
approximately 1ft (30cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled. If necessary,
call the fire department.Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.!Do not push the hood closed manually,
as this could damage it.
iDo not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz will
restrict your warranty entitlement.
More information on this subject is
available at any Mercedes-Benz Light
Truck Center.

the readout of diagnostic trouble
codes. It is located in the front left area
of the footwell next to the parking
brake pedal.

line as determined by a standardized
method. It is an indication of a gaso-

and RON (Research Octane Number) is
posted at the pump, also known as
