Releasing roll bars manually
If the roll bar system is malfunctioning, you
can release the roll bars manually.Close the soft top (page 257).
Open the trunk (page 109).
Fold back the luggage cover
(
page 260).
Take hex wrench out of its storage
location in the storage well casing
(
page 405).1PerforationPush hex wrench through
perforation1 in trim of rear wall in
trunk.
Warning!G
If the yellow roll bar warning lamp in
the clock does not go out after starting the
engine, or if it comes on while driving, then
the roll bar system is not operating properly
and may not activate in an accident. In this
case, raise the roll bars manually before
continuing to drive.
For safety reasons drive only with the roll
bars raised until the malfunction is repaired.
Have your vehicle checked at an authorized
Mercedes-Benz Center.
iWith the roll bars released, the soft top can-
not be operated using the soft top switch and the
rear head restraints cannot be lowered using the
rear head restraint lowering switch.
Warning!G
Make sure no one is located in the roll bar’s
path of motion while the next steps are be-
ing carried out.
When the roll bar is manually released, the
rear head restraints and the roll bar under-
neath shoot up almost instantaneously.


450 Practical hints
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 (12 V). Jump start-
ing with a higher voltage battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.

Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.

Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when an engine is
started or running.
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.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Do not tow-start the vehicle.
!Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the
nearest authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the catalyt-
ic converter and may present a fire risk.
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 at-
tached to a battery.
Warning!G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(
page 321).

451 Practical hints
Jump starting
The battery is located on the right side of
the engine compartment. For jump start-
ing, use the terminals in front of the bat-
tery.
Make sure the two vehicles do not
touch.
Turn off all electrical consumers.
Apply the parking brake (page 59).
Make sure the gear selector lever is set
to positionP (
page 172).
Open the hood (page 315).
Flip up cover from positive under hood
terminal2 in front of the filter box
(
page 448).1Positive terminal of charged battery
2Positive under hood terminal in front of
discharged battery
3Negative under hood terminal in front
of discharged battery
4Negative terminal of charged battery
Connect the positive terminal1 of the
charged battery with the positive under
hood terminal 2 in front of the filter
box with the jumper cable. Clamp cable
to charged battery1 first.
Start engine of the vehicle with the
charged battery and run at idle speed.
Connect the negative terminal4 of
the charged battery with the negative
under hood terminal 3 in front of the
filter box with the second jumper cable.
Clamp the cable to the negative
terminal4 of the charged battery
first.
Start the engine of the disabled vehi-
cle.
You can now turn on the electrical con-
sumers. Do not switch on the headlamps
under any circumstances.
Remove the jumper cables first from
the negative terminals3 and4 and
then from the positive terminals2
and1.
You can now switch on the headlamps.
Have the battery checked at the near-
est authorized Mercedes-Benz Center.
!Never invert the terminal connections.

453 Practical hints
Towing the vehicle
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.
iTo signal turns while being towed with the
hazard warning flasher in use, switch on the igni-
tion and activate the combination switch for the
left or right turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
!When towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, or
KEYLESS-GO* start/stop button 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 central locking
(
page 164).
Towing of the vehicle should only be done using
the properly installed towing eye bolt. Never at-
tach tow cable, tow rope or tow rod to the vehi-
cle chassis, frame or suspension parts.
iIf the battery is disconnected or discharged

the SmartKey will not turn in the starter
switch. For more information, see “Battery”
(
page 447) and “Jump starting”
(
page 450).

the gear selector lever will remain locked in
positionP. For information on manually un-
locking the transmission gear selector lever,
see (
page 412).
