Warning!
G
When leaving the vehicle always remove the
key from the starter switch, take the Smart-
Key with KEYLESS-GO* (if so equipped) with
you and lock the vehicle. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause serious
personal injury.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in position P.
!If the key is left in starter switch
position0 for an extended period of
time, it can no longer be turned in the
starter switch.

Remove the key from the starter
switch and reinsert.
If the key can still not be turned, the
battery may not be sufficiently
charged.

Check the battery and charge it
if necessary (
page 266).

Get a jump start (
page 346).
To prevent accelerated battery dis-
charge or a completely discharged bat-
tery, always remove the key from the
starter switch.

304 Practical hintsWhat to do if …#
Undervoltage
Switch off
consumers
The battery has insufficient voltage.

Turn off unnecessary electrical con-
sumers.
–
Battery/Alternator
Visit workshop!
The battery was charged with a battery
charger or jump started.
The battery is no longer charging. Possible
causes:

Alternator malfunctioning


Broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be operat-
ing with restricted capability. Considerably
greater brake pedal force is required and
the stopping distance is increased.

Have the battery checked at a ser-
vice station.

Stop immediately and check the
poly-V-belt.
If it is broken:
Do not continue to drive. Notify
an authorized Mercedes-Benz
Center.
If it is in order:

Drive immediately to the nearest
authorized Mercedes-Benz Cen-
ter. Adjust driving to be consis-
tent with reduced braking
responsiveness.

Batteries
Batteries
Your vehicle is equipped with two batter-
ies:

Auxiliary battery (back-up battery; en-
ables vehicle to shut down electrical
systems in a controlled manner should
the main battery fail; auxiliary battery is
located in the engine compartment)


The main battery (battery for starter
and electrical consumers; located in
the trunk).The main battery is in the trunk under the
luggage box. Remove the luggage box
(
page 325).
Main battery in trunk1Negative terminal
2Positive terminalWarning!
G
Jump starting must only be done using the
main battery in the trunk.
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.

346 Practical hintsJump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only jump start from batteries with the
same voltage rating.


Use only jumper cables with sufficient
cross-section, insulated terminal
clamps and polarity reversal protec-
tion.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, 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 very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
Read all instructions before proceeding.
iJumper cables with polarity reversal
protection are available at any autho-
rized Mercedes-Benz Center.
!Jump starting may only be performed
on the main battery installed in the
trunk.
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.

347 Practical hints
Jump starting
The battery is located in the trunk on the
right hand side underneath the luggage
box (
page 325). Only jump start the ve-
hicle from the battery in the trunk.

Make sure that the two vehicles do not
touch.

Turn off all electrical consumers.

Apply parking brake.

Shift selector lever to positionP.1Positive terminal of charged battery
2Positive terminal of discharged battery
3Vehicle ground
4Negative terminal of charged battery

Connect positive terminals1 and2 of
the batteries with the jumper cables.
Clamp cable to charged battery1 first.

Start engine of the vehicle with the
charged battery and run at idle speed.

Connect negative terminal4 of the
charged battery and vehicle ground3
(lock ring of the trunk lid lock) in the
trunk with the jumper cable. Clamp ca-
ble to charged battery4 first.

Start the engine of the disabled vehi-
cle.
Now you can again turn on the electrical
consumers. Do not turn on the lights under
any circumstances.

Remove the jumper cables first from
vehicle ground3 and negative
terminal4 and then from positive
terminals1 and2.

Have the battery checked at the next
authorized Mercedes-Benz Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 266).
iThe message
Malfunction - electric
consumers switched off
may appear
in the instrument cluster. It will disap-
pear as soon as the battery is suffi-
ciently charged.
!Vehicles with automatic transmission:
Do not tow-start the vehicle.

350 Practical hintsTowing the vehicle
Installing towing eye bolt
Front of vehicle
1Cover on right side of front bumperTo remove cover:

Press mark on cover in direction of ar-
row.

Lift cover off to reveal threaded hole for
towing eye bolt.
The towing eye bolt is supplied with the
tool kit (located in the storage compart-
ment under the trunk floor).

Screw towing eye bolt in to its stop and
tighten with lug wrench.
To reinstall cover:

Fit cover and snap into place.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the key in starter switch
position2, or KEYLESS-GO* start/stop
button (if so equipped) in position2,
the vehicle doors lock if the left front
wheel as well as the right rear wheel
are turning at vehicle speeds of approx.
9 mph (15 km / h) or more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 99).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
iThe selector lever will remain locked in
positionP and the key will not turn in
the starter switch if the battery is dis-
connected or discharged. See notes on
the battery (
