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 
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.Stolen Vehicle Recovery services
In the event your vehicle was stolen:
Report the incident to the police.
The police will issue a numbered 
incident report.
Pass this number on to the 
Mercedes-Benz Response Center along 
with your password issued to you when 
you subscribed to the service.
The Response Center will then attempt 
to covertly contact the vehicle’s 
Tele Aid system. Once the vehicle is 
located, the Response Center will 
contact the local law enforcement and 
you. The vehicle’s location will only be 
provided to law enforcement.
iThe remote door unlock feature is 
available if the relevant cellular phone 
network is available.
The SOS button will flash and the 
message 
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 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 recessed handle again.
iWhen the anti-theft alarm or the 
tow-away alarm stays on for more than 
30 seconds, a call is initiated automat-
ically to the Response Center, see “An-
ti-theft alarm system” (
page 90) and 
tow-away alarm (
page 91).

302 OperationDriving instructionsStanding water
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 
an authorized Mercedes-Benz Center.Control and operation of radio trans-
mitters

!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 dam-
age is not covered by the 
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as 
securely 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 re-
sponsibility 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 
(approximately 14 m) every second.

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, 
especially 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. 
Always lower the vehicle onto sufficient 
capacity jackstands before working under 
the vehicle.

G
The dimensions of the Minispare wheel are 
different from those of the road wheels. As 
a result, the vehicle handling characteristics 
change when driving with a Minispare wheel 
mounted.
The Minispare wheel should only be used 
temporarily, and should be replaced with a 
regular road wheel as quickly as possible.
