Problem Possible causes/consequences and
000B Solutions
The engine cannot be
started using the
SmartKey. The on-board voltage is too low.
X
Switch off non-essential consumers, e.g. seat heating or interior
lighting, and try to start the engine again.
If this does not work:
X Check the starter battery and charge it if necessary
(Y page 299).
or
X Jump-start the vehicle (Y page 303).
or
X Consult aqualified specialist workshop. The engine cannot be
started using the
SmartKey. The steering lock is mechanically blocked.
X
Remove the SmartKey and reinsert it into the ignition lock. While
doing this, turn the steering wheel in both directions. Doors

WARNING
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
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 or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is arisk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
You should preferably place luggageorl oads
in the cargo compartment. Observe the
loading guidelines (Y page 250). Unlocking and opening doors from

Problems with the engine
Problem Possible causes/consequences and
000B Solutions
The engine does not
start. The HOLD function or DISTRONIC PLUS is activated.
X
Deactivat ethe HOLD function (Y page 171) or DISTRONIC
PLUS (Y page 162).
X Try to start the engine again. The engine does not
start. The starter motor
can be heard. R
There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
X Turn the SmartKey back to position 0in the ignition lock before
attempting to start the engine again.
X Try to start the engine again (Y page 137). Avoid excessively
long and frequent attemptstos tart the engine as these will drain
the battery.
If the engine does not start after several attempts:
X Consult aqualified specialist workshop. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-start the vehicle (Y page 303).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop, e.g. an authorized
Mercedes-Benz Center. The starter motor was exposed to
athermal load that was too high.
X Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult aqualified specialist workshop. 142

WARNING
Work carrie dout incorrectly on the battery
can lead, for example, to ashort circui tand
thus damage the vehicl eelectronics. This can
leadtof unction restrictions applying to
safety-relevant systems ,e.g. the lighting
system, ABS (anti-lock braking system) or
ESP ®
(Electronic Stability Program). The
operating safety of yourv ehicle may be
restricted. You could lose control of the
vehicle, for example:
R braking
R in the event of abrupt steerin gmaneuver
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilar
incident, contact aqualified specialist
workshop immediately. Do not drive any
further. You should have all work involvin gthe
batter ycarried out at aqualifie dspecialist
workshop.

WARNING
Electrostatic build-up can lead to th ecreation
of sparks ,whic hc ould ignite th ehighly
explosive gases of abattery. Ther eisariskof
an explosion.
Before handlin gthe battery, touch th evehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixtur eforms when
chargin gthe battery as well as when jump-
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 discharged300

i
Remove th eSmartKey if you park the
vehicl eand do no trequire any electrical
consumers. The vehicle will then use very
little energy, thus conservin gbattery
power.
i If the power supply has been interrupted,
e.g. if you reconnectt he battery, you will
have to:
R set the clock (audio system/COMAND,
see the separate operating instructions).
R reset the function for folding the exterior
mirrors in/out automatically ,byfolding
the mirrors out once (Y page 100).Charging the battery
G
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
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. 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 303).
X Open the hood.
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 303).
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 jump-start the vehicle nor
charge the battery. The service life of a
thawed-out battery may be shorter. The
startingc haracteristics can be impaired,
particularly at low temperatures. Have the
thawed-out battery checked at aqualified
specialist workshop.
Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. An accessory
battery charge unit specially adapted for
Mercedes-Ben zvehicles and tested and
approved by Mercedes-Benzisa vailable. 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. 302
