Useful features
When the connection is established, the
message
Call connected
appears in the
multifunction display. The Tele Aid system
will transmit data generating the vehicle
identification number, model, color and
location (subject to availability of cellular
and GPS signals).
A voice connection between the Roadside
Assistance dispatcher and the occupants
of the vehicle will be established.

Describe the nature of the need for as-
sistance.The Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest
Mercedes-Benz Light Truck Center. For
services such as labor and/or towing,
charges may apply. Refer to the Roadside
Assistance Manual for more information.
These programs are only available in the

Visit workshop
The battery was charged with a
battery charger or jump started.

Have the battery checked at a service
station.
Battery/Alternator
Stop vehicle
The battery is no longer charg-
ing.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake sys-
tem requires electrical energy
and may be operating with re-
stricted capability. Considerably
greater brake pedal force is
required and the stopping dis-
tance is increased.

Stop immediately and check the
poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise the
engine will overheat due to an inoperative
water pump which may result in damage
to the engine. Notify an authorized
Mercedes-Benz Light Truck Center.
If it is intact:

Drive immediately to the nearest autho-
rized Mercedes-Benz Light Truck Center.
Adjust driving to be consistent with re-
duced braking responsiveness.

463 Practical hints
Battery
!
The battery is a valve-regulated lead
acid (VRLA) battery, also referred to as
“fleece” battery. Such batteries do not
require topping-up of the electrolyte
level. VRLA batteries therefore do not
have cell caps and the battery cover is
non-removable. Do not attempt to
open the battery as otherwise the bat-
tery will be damaged.
Even though VRLA batteries do not
require topping-up of the electrolyte
level and cannot be opened to check
the electrolyte level, the battery condi-
tion must be checked periodically by
performing a battery conductance test.
Refer to Maintenance Booklet for bat-
tery condition testing intervals.
As with any other battery, the battery
may discharge if the vehicle is not
operated for an extended period of
time. You can connect a battery
maintenance charge unit tested and
approved for use on your vehicle model
or disconnect the battery to prevent
battery discharge. Contact an
authorized Mercedes-Benz Light Truck
Center for more information.
!The factory-equipped VRLA battery is
leak-proofed. Only use a battery as re-
placement that has the same security
features and is of identical size,
voltage, and capacity as the
factory-equipped battery.
The battery, the battery ventilation
tube (
page 468) and the vent plug
(
page 468) must always be securely
installed when the vehicle is in opera-
tion.
Warning!
G
Jump starting must only be done using the
jump-start contacts located in the engine
compartment (
page 470).

464 Practical hintsBattery
Disconnecting, removing, reinstalling and reconnecting the battery
Warning!
G
Failure to follow these instructions can re-
sult in severe injury or death.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 462).
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.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the SmartKey is in the starter switch.
Otherwise the alternator and other
electronic components could be se-
verely damaged.
Have the battery checked regularly by
an authorized Mercedes-Benz Light
Truck Center.
Refer to Maintenance Booklet for main-
tenance intervals or contact your au-
thorized Mercedes-Benz Light Truck
Center for further information.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
Warning!
G
Disconnecting, removing, reinstalling and
reconnecting the battery is a complicated
and technically demanding procedure that
also requires safety precautions to avoid the
r i s k o f i n j u r y . W e s t r o n g l y r e c o m m e n d t h a t i t
be performed by a qualified technician only.
