WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turninga gain.G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R startingt he engine.
They could also operate the vehicle's
equipment. There is arisk of an accident and
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. If you brake the vehicle with the parking
brake, the brake lamps will not light up. X
To apply: depress parking brake 0010firmly.
When the engine is running, the 0004(USA
only) or 0001(Canada only) indicator lamp
lights up in the instrumen tcluster.
X To release: depressthe brak epedal and
keep it depressed.
X Pull release handle 001A.
When the ignition is switched on or the
engine is running, the 0004(USA only) or
0001 (Canada only) indicator lamp goes out
in the instrumen tcluster. Parking th

If you leave th evehicle parked for longer than
four weeks, th ebattery may be damage dby
exhaustive discharging.
If you leave th evehicle parked for longer than
six weeks, th evehicle may suffer damage as

Befor
ehandling the battery ,touch the vehicle
bod ytor emove any existing electrostatic
build-up.
The highly flammable ga smixture forms when
charging the battery as well as whe njump-
starting.
Always mak esure that neither you no rthe
battery is electrostatically charged. Abuild-
up of electrostati ccharge 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 acloth G
WARNING
During the charging process, abattery
produces hydrogen gas. If ashort circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objectsort ools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and
disconnecting the jumper cables.
R Never connect or disconnectt he battery
terminals while the engine is running. G
WARNING
Batterya cid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment. Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to aqualified
specialist workshop or a
special collection point for
used batteries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the
MaintenanceB ooklet or contact aqualified
specialist workshop for more information.
! You should have all work involving the
battery carried out at aqualified specialist
workshop. In th eexcepti onal cas ethatitis
necessar yfor you to disconnect th ebattery
yourself, mak esure that:
R you switch off th eenginea nd remove the
SmartKey. On vehicles wit hKEYLESS-
GO, ensure that th eignition is switched
off .C heck that all the indicator lamps in
the instrumentc luster are off.Otherwise,
electroni ccomponents, such as the
alternator ,may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic
system may be damaged.
R the transmission is locked in position P
after disconnectingt he battery. The
vehicle is secured against rolling away.
You can then no longer move the vehicle. Battery (vehicle)
323Breakdown assistance Z
The battery and the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precautions and take
protective measures when handling
batteries. Risk of explosion.
Fire, open flames and smokin
gare
prohibited when handling the
battery. Avoid creatin gsparks. Battery acid is caustic. Avoid
contact with skin, eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and
faceguard.
Rinse any acid spills immediately
with clear water. Contact a
physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz
recommends that you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz.T hese
batteries provide increased impact
protection to prevent vehicle occupants from
suffering acid burns should the battery be
damaged in the event of an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery disconnected at
aqualified specialist
workshop. You can also charge the battery
with acharger recommended by Mercedes-
Benz.C ontactaqualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standin gidle
for alengthy period. Consult aqualified
specialist workshop if you wish to leave your
vehicle parked for along period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
i If the power supply has been interrupted,
e.g. if you reconnect the battery, you will
have to:
R set the clock.I nformation on setting the
clock can be found in the separate
operating instructions.
On vehicles with COMAND and a
navigation system, the clock is set
automatically.
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 110). Charging the battery

WARNING
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 abattery. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean 324

over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. G
WARNING
Ad ischarged battery can freeze at
temperatures below freezin gpoint .When
jump-starting the vehicle or charging the
battery, gases can escape from the battery.
There is arisk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a
maximum charging voltage of 14.8 V.
! Only charge the battery using the jump-
startingc onnection point.
The jump-starting connection point is in the
engine compartment( Ypage 326).
X Open the hood (Y page 306).
X Connect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure
(Y page 326).
If, at low temperatures, the indicator lamps/
warning lamps in the instrumentc luster do
not light up, it is highly likely that the
discharged battery has frozen.Int his case,
you may neither charge the battery nor jump-
start the vehicle. The service life of athawed-
out battery may be shorter. The starting
characteristics may be impaired, especiallyat
low temperatures. Have the thawed-out
battery checked at aqualified specialist
workshop.
Never charge abattery still installed in the
vehicle unless abattery charger unit
approved by Mercedes-Ben zisbeing used. A
battery charger unit speciallya dapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for further information and availability. Read the battery
charger's operating instructions before
charging the battery. Battery (vehicle)
