Useful features
Power outlet
The power outlet is located on the left side
in the trunk.
1Power outlet
Switch on the ignition (page 40).
Flip up cover and insert electrical plug
(cigar lighter type).
Telephone
The telephone is located in the center
storage compartment (
page 207).
!The lighter socket can accommodate
12V DC electrical accessories (up to a maximum
of 85 W) designed for use with the standard
“cigarette lighter” plug type. Keep in mind, how-
ever, that connecting accessories to the lighter
socket (for example extensive connecting and
disconnecting, or using plugs that do not fit prop-
erly) can damage the lighter socket. With the
socket damaged, the lighter may no longer be
able to be placed in the heating (pushed-in) posi-
tion, or the lighter may pop out too early with the
lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with a stan-
dard “cigarette lighter” plug type to the
12 V power outlets in your vehicle whenever
possible.
iThe power outlet can be used to accommo-
date 12V DC electrical accessories (e.g. air
pump, auxiliary lamps) up to a maximum
of 180 W or as a battery charging point
(
page 368).
Warning!G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and personal
injury.

302 Practical hints
What to do if ...
ProblemPossible cause/consequenceSuggested solutions
-The yellow ABS indicator
lamp comes on while the
engine is running.Risk of accident!
The ABS has detected a malfunction and
has switched off. The BAS and the ESP
®
are also switched off.
If the ABS control unit is malfunctioning,
other systems such as the automatic
transmission may also be malfunctioning.
The electro-hydraulic brake system is still
functioning normally but without ABS
available.
Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.
Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.
Read and observe messages in the
multifunction display (
page 314).
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged
sufficiently.When the voltage is above this value again, the
ABS is operational again and the ABS indicator
lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.

What to do if ...
Left displayRight displayPossible cause/
consequencePossible solution
#The battery is no longer
charging. Possible causes:

alternator malfunctioning

broken poly-V-belt
Do not forget that the brake
system requires electrical
energy and may be operating
with restricted capability.
Considerably greater brake
pedal force is required and the
pedal travel is longer. The stop-
ping distance is increased. If
necessary, apply full pressure
to the brake pedal.
Stop the vehicle immediately in a safe location and
check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise, the engine will
overheat due to an inoperative water pump which
may result in damage to the engine. Contact an
authorized Mercedes-Benz Center.
If it is in order:
Contact an authorized Mercedes-Benz Center imme-
diately. Adjust driving to be consistent with reduced
braking responsiveness.
Read and observe additional messages in the
multifunction display.
The starter battery has been
charged with a battery charger
or jump started.Contact an authorized Mercedes-Benz Center.
There is a malfunction in the
electronic system.Have the system checked at an authorized
Mercedes-Benz Center immediately.

Batteries
Your vehicle is equipped with two batter-
ies:

The starter battery (located in the
trunk)

The battery for electrical consumers
(located in the trunk)
Warning!G
Failure to follow these instructions can
result in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Observe all safety instructions and precau-
tions when handling automotive batteries
(
page 256).
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.
!You must not jump start the vehicle, other-
wise the vehicle electrical systems could be
damaged.
Only use the battery charge unit tested and ap-
proved by Mercedes-Benz for use on the SLR to
charge the battery or maintain the battery
charge. Using other battery chargers may cause
damage to the vehicle and/or personal injury.
Information on charging the batteries
(
page 368).
Have the batteries checked regularly by an
authorized Mercedes-Benz Center. Refer to
Maintenance Booklet for maintenance intervals
or contact an authorized Mercedes-Benz Center
for further information.
If it is necessary to replace the batteries, contact
an authorized Mercedes-Benz Center.
Warning!G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof batteries only to avoid the
risk of acid burns in the event of an
accident.

Charging the batteries
You can obtain detailed information on
charging the battery from your authorized
Mercedes-Benz Center.
Warning!G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. The same applies if
battery is disconnected. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is
increased! Adjust your driving style
accordingly. For more information, see
“Electro-hydraulic brake system”
(
page 86).
Warning!G
With a disconnected battery

you will no longer be able to turn the
SmartKey in the starter switch

the gear selector lever will remain
locked in park positionP
Warning!G
Never charge a battery while still installed in
the vehicle unless the battery charge unit
approved by Mercedes-Benz (supplied with
your vehicle) is being used. Gases may es-
cape during charging and cause explosions
that may result in paint damage, corrosion
or personal injury.
A battery charge unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available,
permitting the charging of the battery in its
installed position. Contact an authorized
Mercedes-Benz Center for information and
availability. Charge battery in accordance
with the separate operating instructions for
the battery charger.

369 Practical hints
Batteries
Charging with the battery charger
Only use the battery charge unit approved
by Mercedes-Benz and supplied with your
vehicle. This charger is designed to auto-
matically control the charge rate, and
charge the battery or maintain the existing
charge in the battery while the vehicle is
parked and not being driven for long
periods of time (on average approximately
3 weeks or more). Not driving the vehicle
for such extended periods may cause the
charge in the vehicle battery to drop.
Using the charging point
The charging point for the battery charger
is located next to the CD-changer on the
left-hand side in the trunk.1Charging point
Remove the SmartKey from the starter
switch.
Open the cover of the charging
point1.
Connect the battery charger with the
charging point 1.
Observe and follow the separate
operating instructions for the battery
charger.
Charge up the battery.
The battery charger switches off
automatically when the battery is
sufficiently charged.Using the charging terminals
The charging terminals for the battery
charger are located in the trunk under-
neath the interior floor.
1Negative charging terminal
2Positive charging terminal
Connect positive terminal2 and
negative terminal1 with the battery
charger. Start with the positive
terminal2.
Charge up the battery. Observe and fol-
low the separate operating instructions
for the battery charger.
