Pull at top of cover2.

Flip cover1 to the left and insert
electrical plug (cigarette lighter type).
!The lighter socket can be used to ac-
commodate 12V DC electrical acces-
sories (up to a maximum of 85 W)
designed for use with the standard
“cigarette lighter” plug type. Keep in
mind, however, that connecting acces-
sories to the lighter socket (for exam-
ple extensive connecting and
disconnecting, or using plugs that do
not fit properly) can damage the lighter
socket. With the socket damaged, the
lighter may no longer be able to be
placed in the heating (pushed-in) posi-
tion, or the lighter may pop out too ear-
ly with the lighter not hot enough.
To help avoid damaging the cigarette
lighter socket, we recommend con-
necting 12V DC electrical accessories
designed for use with the standard
“cigarette lighter” plug type to the 12V
power outlets (
page 263) in your ve-
hicle whenever possible.
iThe power outlet can be used to
accommodate 12V DC electrical ac-
cessories (e.g. air pump, auxiliary
lamps) up to a maximum of 180 W.

Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message
Malfunction. Drive to work-
shop
appears in the multifunction display.
iThe SOS button is located in the over-
head control panel.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
iWhen a Tele Aid call has been initiated,
the audio system or COMAND* System
unit is muted and the selected mode
(radio, tape or CD) pauses. The optional
cellular phone (if installed) and inserted
in cradle switches off. If you must use
this phone, we recommend that you
use it only with the vehicle at a stand-
still in a safe location. Remove the

priority and override all other active calls.
iThe indicator lamp in the Information
button¡ remains illuminated in red
for approximately 10 seconds during
the system self-check after switching
on the ignition (together with the
SOS button and the Roadside
Assistance button•).
See system self-check (
page 266) if
the indicator lamp does not come on in
red or stays on longer than
approximately 10 seconds.
If the indicator lamp in the Information
button¡ is flashing continuously
and there was no voice connection to
the Response Center established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
Call failed
ap-
pears in the multifunction display.

Programming or reprogramming the
integrated remote control
Step 1:
Switch on the ignition (
page 33).Step 2:

If you have previously programmed an
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.
Warning!
G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
- signaling the door to stop and reverse -
does not meet current U.S. federal safety
standards.
When programming a garage door opener
park the vehicle outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and
possible death.

Proceed with programming step 5 and
step 6 to complete. Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:

Switch on the ignition (
page 33).

Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.

The indicator lamp1 will begin to
flash after 20 seconds. Without releas-
ing the signal transmitter button, pro-
ceed with programming starting with
step 3.Operation of integrated remote control

Switch on the ignition (
page 33).

Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.
iUpon completion of programming the
integrated remote control, make sure
you retain the hand-held remote con-
trol that came with the garage door
opener, gate operator or other device.
You may need it for use in other vehi-
cles, for future programming of an
integrated remote control, or simply for
continued use as a hand-held remote
control to operate the respective
device in other situations.

Erasing the integrated remote control
memory
Switch on the ignition (
page 33).

Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:


Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.


Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.


While performing step 3, hold the
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.


If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.


Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iIf you sell your vehicle, erase the codes
of all three channels.
iCertain types of garage door openers
are incompatible with the integrated
remote control. If you should experi-
ence further difficulties with program-
ming the integrated remote control,
contact an authorized Mercedes-Benz
Center, or call Mercedes-Benz
Customer Assistance Center (in the
USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

298 OperationEngine compartment
Closing
Let the hood drop from a height of
approximately 1 ft (30 cm).
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
(ignition coils, spark plug sockets, diagnos-
tic 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.
iDo not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
More information on this subject is
available at any Mercedes-Benz
Center.
