Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. SmartKey inside vehicle),
and the reserve SmartKey is not handy:
Contact the Mercedes-Benz Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
You will be asked to provide your pass-
word which you provided when you
completed the subscriber agreement.
Then return to your vehicle and pull the
trunk recessed handle for a minimum
of 20 seconds until the SOS button is
flashing.
The message
Emergency call –
Call connected appears in the multi-
function display.
As an alternative, you may unlock the vehi-
cle via Internet using the ID and password
sent to you shortly after the completion of
your acquaintance call.The Response Center will then unlock your
vehicle with the remote door unlocking
feature.
iWhen a Tele Aid call has been initiated,
the audio system or the COMAND* sys-
tem audio is muted and the selected
mode (radio, tape or CD) pauses. The
optional cellular phone (if installed)
switches off. If you must use this
phone, the vehicle must be parked. Dis-
connect the coiled cord and place the
call. The COMAND* navigation system
(if engaged) will continue to run. The
display in the instrument cluster is
available for use and spoken com-
mands are only available by pressing
the RPT button on the COMAND* unit.
A pop-up window will appear in the
COMAND* display to indicate that a
Tele Aid call is in progress.
iThe remote door unlock feature is avail-
able if the relevant cellular phone net-
work is available.
The SOS button will flash and the mes-
sage
Emergency call –
Call connected
will appear in the mul-
tifunction display to indicate receipt of
the door unlock command.
Once the vehicle is unlocked,
a Response Center specialist will at-
tempt to establish voice contact with
the vehicle occupants.
If the trunk recessed handle was pulled
for more than 20 seconds before door
unlock authorization was received by
the Response Center, you must wait
15 minutes before pulling the trunk re-
cessed handle again.

!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks immediately. Noti-
fy an authorized Mercedes-Benz Center
immediately. Do not add brake fluid as
this will not solve the problem. For

282 OperationEngine compartment
Closing
Let the hood drop from a height of ap-
proximately 1 ft (30 cm).
The hood will lock audibly.
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.
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 the vehicle and do not open the
hood until the engine has cooled. If neces-
sary, 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.
