See Oper. Manual
The passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front pas-
senger seat is empty. Objects
on the seat or forces acting on
the seat may make the system
sense supplemental weight.
Stop the vehicle in a safe location as soon as possible and
check the passenger seat for the following:
Switch off the ignition (
page 39).

Remove child and child restraint from passenger seat and
properly secure the child in rear seat employing the child
restraint if necessary.

Make sure that no objects which applying supplemental
weight onto the seat are present. The system may recog-
nize such supplemental weight and sense that an occu-
pant on the passenger seat is of a greater weight than
actually present.

Keep the seat unoccupied, close the passenger door and
switch on the ignition (
page 39).
Monitor the 5/indicator lamp between the center air
vents and the multifunction display in the instrument cluster
(

414 Practical hintsBatteriesFor more information on batteries, see
“Battery” (
page 281).
Your vehicle is equipped with two
batteries:


The starter battery


The battery for electrical consumers
(consumer battery), located in the
trunk
The starter battery is located on the
right-hand side of the engine compart-
ment.
1Positive terminal
2Negative terminal
3Battery ventilationThe consumer battery is located on the
right-hand side of the trunk.
4Positive terminal
5Negative terminal
!
The starter battery, its filler caps, and the
ventilation hose must always be securely in-
stalled when the vehicle is in operation.
!
The consumer battery located in the trunk 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 consumer battery as other-
wise the battery will be damaged.
Even though VRLA batteries do not require top-
ping-up of the electrolyte level and cannot be
opened to check the electrolyte level, the bat-
tery condition must be checked periodically by
performing a battery conductance test. Refer to
Maintenance Booklet for battery condition test-
ing intervals.
As with any other battery, disconnect the con-
sumer battery if you do not intend to operate
your vehicle for an extended period of time to
prevent battery discharge or connect an acces-
sory battery charge unit expressly approved by
Mercedes-Benz for your vehicle model to main-
tain the battery charge. Contact an authorized
Mercedes-Benz Center for further information.

415 Practical hints
Batteries
!
The factory-equipped VRLA battery is
leak-proofed. Only use a battery as replacement
that has the same security features and is of
identical size, voltage, and capacity as the
factory-equipped battery.
The battery, the battery ventilation and the later-
al plug must always be securely installed when
the vehicle is in operation.
Warning!
G
Failure to follow these instructions can re-
sult 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.
!
Never loosen or detach battery terminal
clamps while the engine is running or the
SmartKey is in the starter switch. Otherwise the
alternator and other electronic components
could be severely damaged.
Have the starter battery checked regularly by an
authorized Mercedes-Benz Center.
Refer to Maintenance Booklet for maintenance
intervals or contact an authorized
Mercedes-Benz 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 batteries only to avoid the
risk of acid burns in the event of an acci-
dent.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. The same applies if
battery is disconnected. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adjust your driving style according-
ly. For more information, see
“Electro-hydraulic brake system”
(page 92).

417 Practical hints
Batteries

Open the hood (
page 274).

Use the 10 mm open-end wrench from
the vehicle tool kit to disconnect the
negative lead from negative
terminal2 of the starter battery
(page 414).

Remove the covers from the positive
terminals 1 and 4 (
page 414).

Disconnect the positive lead from pos-
itive terminal 4 of the consumer bat-
tery (
page 414).

Disconnect the positive lead from pos-
itive terminal 1 of the starter battery
(page 414).
Removing the batteries
Removing the consumer battery
Remove the screws securing the bat-
tery in the trunk.

Remove the battery support and
bracket.

Pull out the battery ventilation hose
from the battery.
Depending on battery arrangement in
your vehicle model, the ventilation tube
is located either on the left or right side
of the battery.

Take out the battery.
Removing the starter battery

Remove the screws securing the start-
er battery in the engine compartment.

Pull battery ventilation 3
(page 414) out of the battery.

Lift the retaining bracket.

Remove the battery.
Charging and reinstalling batteriesWarning!
G
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the bat-
tery in its installed position. Contact an au-
thorized Mercedes-Benz Center for
information and availability. Charge battery
in accordance with the separate instruc-
tions for the accessory battery charger.

424 Practical hintsFusesThe electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses. They are located in the trunk
with the vehicle tool kit (
page 388).


Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.


Spare fuses


Fuse extractor
The electrical fuses are located in different
fuse boxes:


on the driver’s side of the engine com-
partment (
page 425)


on the passenger side of the engine
compartment (
page 425)


under passenger-side rear storage
compartment (
page 426)


in the trunk (
page 426)Before replacing fuses:

Apply the parking brake (
page 61).

Make sure the gear selector lever is set
to position P (
page 168).

Turn off all electrical consumers.

Turn off the engine (
page 62).

Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*: Open
the driver’s door.
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Centeri
A blown fuse must be replaced by an appro-
piate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
