ual
A special BabySmart™-compatible child restraint system is moun-
ted on the front-passenger seat. The 45 indicator lamp also lights up.
The front-passenger air bag is therefore disabled.

ual
The 45 indicator lamp does not remain lit if a special
BabySmart™-compatible child restraint system has been installed
on the front-passenger seat.
The BabySmart™ system is malfunctioning.
GWARNING
The front-passenger front air bag can be triggered unintentionally in the event of an accident.
There is a risk of an accident.
X Make sure there is nothing between the seat and the child
restraint system.
X Check that the child restraint system is installed correctly.
X If the 45 indicator lamp does not light up, have the
BabySmart™ system checked as soon as possible at a qualified
specialist workshop.
Do not transport a child on the front-passenger seat until the air
bag deactivation system has been repaired.

GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This canlead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
If ABS malfunctions, the wheels can lock dur-
ing braking. This limits the steerability of the
vehicle when braking and may increase the
braking distance.
If ESP ®
malfunctions, the vehicle will not be
stabilized if it starts to skid or a wheel starts to spin.
iFor further information about ABS and
ESP ®
, see ( Ypage 65) and ( Ypage 66).
GWARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity areconnected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running.
GWARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-starting.
Always make sure that neither you nor the
battery is electrostatically charged. A build-
up of electrostatic charge can be caused, for
example:
R by wearing clothing made from synthetic
fibers
R due to friction between clothing and seats
R if you push or pull the battery across the
carpet or other synthetic materials
R if you wipe the battery with a cloth
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten- tion.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact a qualified spe- cialist workshop for more information.

little energy, thus conserving battery power.
iIf the power supply has been interrupted,
e.g. due to a discharged battery, you will
have to: R set the clock. Information on setting the
clock can be found in the Digital Opera-
tor's Manual.
On vehicles with COMAND and a naviga-
tion system, the clock is set automati- cally.
R reset the head restraints on the front
seats. Information on resetting the head
restraints can be found in the Digital
Operator's Manual.
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once ( Ypage 87).
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten- tion.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only charge the battery using the jump-
starting connection point.
!Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
!Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while still installed in the vehicle.
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the dis-
charged battery has frozen. In this case you
may neither jump-start the vehicle nor charge the battery. The service life of a thawed-out
battery may be shorter. The starting charac-
teristics can be impaired, particularly at low
temperatures. Have the thawed-out battery
checked at a qualified specialist workshop.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Contact an authorized Mercedes-
Benz Center for information and availability.
Charge the battery in accordance with the
operating instructions for the battery
charger.
The jump-starting connection point is in the
engine compartment ( Ypage 220).
X Read the operating instructions for the bat-
tery charger.
X Open the hood ( Ypage 205).
X Connect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor bat-
tery in the jump-starting procedure( Y page 220).
