Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. SmartKey inside vehicle),
and the reserve key 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 lid recessed handle for minimum
of 20 seconds until the SOS button is
flashing.
The message
Connecting call
appears in the multifunction 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*
system audio is muted and the select-
ed 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.
Disconnect the coiled cord and place
the call. The COMAND* navigation
system (if engaged) will continue to
run. The display in the instrument clus-
ter 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
Connecting call
will appear in
the multifunction display to indicate
receipt of the door unlock command.
Once the vehicle is unlocked, a
Response Center specialist will
attempt to establish voice contact with
the vehicle occupants.
If the trunk lid recessed handle was
pulled for more than 20 seconds be-
fore door unlock authorization was re-
ceived by the Response Center, you
must wait 15 minutes before pulling
the trunk lid recessed handle again.

Passenger compartmentDriving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from

!Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such
damage is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry
objects.
Warning!
G
Please do not forget that your primary
responsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit Man-
agement and Data System), radio or tele-
phone
1 if road, weather and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jack stands before working under the
