2008 MERCEDES-BENZ SL600 brake

434 Practical hints
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised only so
far as necessary to have the vehicle moved
to a safe location where the recommended
towing methods can be employed.
!Do not tow-start the vehicle.
!Use flatbed or wheel lift/dolly equipment
with SmartKey in starter switch turned to
position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Switch off the tow-away alarm (
page 100) and
the automatic central locking (
page 166).
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run

there is a malfunction in the
electro-hydraulic brake system

there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position2.
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. 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! Adapt your driving style
accordingly. For more information, see
“Electro-hydraulic brake system”
(
page 94).
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.

435 Practical hints
Towing the vehicle
!If the vehicle is towed with the front axle
raised, the gear selector lever must be in
positionN and the engine must be shut off
(SmartKey in starter switch position0 or1).
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
When towing the vehicle with all wheels on the
ground, the gear selector lever must be in
positionN and the SmartKey must be in starter
switch position2.
When towing the vehicle with all wheels on the
ground or the front axle raised, the vehicle
may be towed only for distances up to
30 miles (50 km) and at a speed not to exceed
30 mph (50 km/h).
!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach a tow cable, tow rope or tow rod to
the vehicle chassis, frame or suspension parts.
iWhen 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 approximately 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 122).
iTo signal turns while being towed with the
hazard warning flasher in use, turn SmartKey in
starter switch to position2 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.
iIf the battery is disconnected or discharged

the SmartKey will not turn in the starter
switch

the gear selector lever will remain locked in
positionP.
For more information, see “Batteries”
(
page 427) and “Jump starting” (page 432).

437 Practical hints
Fuses
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
A fuse chart explains the fuse allocation
and fuse amperages. It is located in the
trunk with the vehicle tool kit
(
page 400).
The electrical fuses are located in different
fuse boxes:

on the driver’s side of the engine com-
partment (
page 438)

on the passenger side of the engine
compartment (
page 438)

under passenger-side rear storage
compartment (
page 439)

in the trunk (page 439)Before replacing fuses:
Apply the parking brake (page 63).
Make sure the gear selector lever is set
to position P (
page 172).
Turn off all electrical consumers.
Turn off the engine (page 64).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*: Open
the driver’s door.
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Center
iA blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
iIn case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-Benz
Center.

Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.Engine oil additives
Air conditioning refrigerant
R-134a (HFC) refrigerant and special
PAG lubricating oil are used in the air con-
ditioner system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any
authorized Mercedes-Benz Center will
provide you with additional information.
!Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System or changing oil and oil filter
at change intervals longer than those called for
by the Maintenance System will result in engine
or emission control system damage not covered
by the Mercedes-Benz Limited Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere. Under extremely strenuous
operating conditions, this moisture content
can lead to the formation of bubbles in the
system, thus reducing the system’s
efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
