Tele Aid
! In order to activate the Tele Aid system, a
subscriber agreement must be completed.
To ensure your system is activated and
operational, please press button E to
perform the acquaintance call. Failure to
complete either of these steps may result
in a system that is not activated.
If you have any questions regarding
activation, please call the Response Center
at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).
Shortly after the completion of your Tele Aid
acquaintance call, you will receive a user ID
and password in the mail. You may use this
password to access the Tele Aid section in
“Owner’s Online” at www.mbusa.com (USA
only). The “My Tele Aid” section will give you
access to account information, remote door
unlock and more.
The Tele Aid system is available if
Rit has been activated and is operational.
Activation requires a subscription for
monitoring services, connection and
cellular air time.
Rvehicle battery power is available.
Rthe relevant cellular phone network and
GPS signals are available and pass the
information on to the Response Center.
iLocation of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network and
pass the information on to the Response
Center.
The Tele Aid system
(Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types
of response:
RAutomatic and manual emergency
RRoadside Assistance
RInformation
The Tele Aid system is operational providing
that the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS (Global
Positioning System) satellites for vehicle
location. If either of these signals are
unavailable, the Tele Aid system may not
function and if this occurs, assistance must
be summoned by other means.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as long as 5 minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the audio system
or the COMAND system. Also, most
functions in the control system, such as the
telephone function, are suspended.
Therefore, it is not advisable to initiate any
Tele Aid call unless the Tele Aid system is
activated and operational.

Replacing SmartKey batteries
If the batteries in the SmartKey are
discharged, the vehicle can no longer be
locked or unlocked. It is recommended to
have the batteries replaced at an authorized
Mercedes-Benz Center.
GWarning!
Batteries contain poisonous and corrosive
substances. Therefore, keep the batteries out
of reach of children.
If a battery is swallowed, seek medical help
immediately.
GWarning!
SmartKey batteries contain perchlorate
material, which may require special handling
and regard for the environment. Check with
your local government’s disposal guidelines.
California residents, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm.
Batteries contain materials that can harm the
environment if disposed of improperly.
Recycling of batteries is the preferred method
of disposal. Many states/provinces require
sellers of batteries to accept old batteries for
recycling.
When inserting the batteries, make sure they
are clean and free of lint.
When replacing batteries, always replace
both batteries.
iThe required replacement batteries are
available at any authorized Mercedes-Benz
Center.
Replacement batteries: Lithium, type
CR 2025 or equivalent.

Replacing bulbs
Safety notes
Safe vehicle operation depends to a large
degree on proper exterior lighting and
signaling.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment.
GWarning!
Bulbs and bulb sockets can be very hot. Allow
the lamp to cool down before changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
Rtouch or move it when hot
Rdrop the bulb
Rscratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iSince replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging.

Battery
Safety notes
A battery should always be sufficiently
charged in order to achieve its rated service
life. Refer to Maintenance Booklet for battery
maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
battery charge checked more frequently.
When replacing a battery, always use a
battery approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe.
GWarning!
Observe all safety instructions and
precautions when handling automotive
batteries.
Risk of explosion.Fire, open flames and
smoking are prohibited
when handling batteries.
Avoid creating sparks.
Battery acid is caustic. Do
not allow it to come into
contact with skin, eyes or
clothing.
Wear suitable protective
clothing, especially gloves,
apron and faceguard.
Wear eye protection.
Rinse any acid spills
immediately with clear
water. Contact a physician
if necessary.
Keep children away.Follow the instructions in
this Operator’s Manual.
Batteries contain materials that can harm the
environment if disposed of improperly. Large
12-volt storage batteries contain lead.
Recycling of batteries is the preferred method
of disposal. Many states (USA only) or
provinces (Canada only) require sellers of
batteries to accept old batteries for recycling.
GWarning!
Failure to follow these instructions can result
in severe injury or death.
Never lean over batteries while connecting.
You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
GWarning!
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof batteries only to avoid the risk
of acid burns in the event of an accident.
Take care that you do not become statically
charged, e.g. by wearing synthetic clothing or
rubbing against textiles. For this reason, you
also should not pull or push the battery over
carpets or other synthetic materials.
Never touch the battery first. First touch the
outside body of the vehicle in order to release
any possible electrostatic charges.

Towing the vehicle
Safety notes
Mercedes-Benz recommends that the vehicle
be transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment. This method is preferable to other
types of towing.
! To prevent damage during transport, do
not tie down vehicle by its chassis or
suspension parts.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
only so far as necessary to have the vehicle
moved to a safe location where the
recommended towing methods can be
employed.
