Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident. R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
R Objects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the rear
door is open when the engine is running, par- ticularly if the vehicle is moving, exhaust
fumes could enter the passenger compart-
ment. There is a risk of poisoning.
Turn off the engine before opening the rear
door. Never drive with the rear door open.

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).
