Low windshield and headlamp washer system fluid
level warning lamp
With the key in steering lock position 2, the
warning lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, the level of the
reservoir has dropped to approx. 1/3 of the total volume.
The reservoir should be refilled with MB Windshield
Washer Concentrate “S” and water (or commercially
available premixed windshield washer solvent/
antifreeze, depending on ambient temperature - see
page 88) at the next opportunity. The reservoir for the
windshield and headlamp washer systems is located in
the engine compartment.Low engine oil level warning lamp
With the key in steering lock position 2, the
oil level warning lamp comes on. It should
go out immediately when the engine is
running.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The low engine oil level warning light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick, for
example during a fuel stop, or before a long trip,
see page 222.

Roll bar warning lamp
With the key in steering lock position 2, the
roll bar warning lamp comes on and goes out
with the engine running.
Have the roll bar system checked at your authorized
Mercedes-Benz Center as soon as possible.ADS indicator lamp
If the malfunction indicator stays on after
the engine is running, then the oil level in
the reservoir is low or the system has
detected a malfunction.
Have the ADS checked at your authorized
Mercedes-Benz Center as soon as possible.
For detailed information see page 199
Wa r n i n g !
If the warning lamp does not go out after starting
the engine, or if it comes on while driving, and the
indicator lamps in the roll bar switch blink
simultaneously, then the roll bar system is not
operating properly and may not activate in an
accident. In this case, raise the roll bar manually
(see page 118) before continuing to drive.

Lower hood and let it drop into lock from a height of
approx. 1 ft. (30 cm), assisting with hands placed flat on
edges of hood (3).
To avoid hood damage, please make sure that hood is
fully closed. If not, repeat closing procedure. Do not
push down on hood to attempt to fully close it.
Wa r n i n g !
To help prevent personal injury, stay clear of
moving parts when the hood is open and the engine
is running. Be sure the hood is properly closed
before driving. When closing hood, use extreme
caution not to catch hands or fingers.The radiator fan may continue to run another
approximate 30 seconds or even restart after the
engine has been turned off. Stay clear from fan
blades.
The engine is equipped with a transistorized
ignition system. Because of the high voltage it is
dangerous to touch any components (ignition coils,
spark plug sockets, diagnostic socket) of the
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned
manually.If you see flames, steam or smoke coming from the
engine compartment, or if the coolant temperature
gauge indicates that the engine is overheated, do
not open the hood. Move away from vehicle and do
not open the hood until the engine has cooled. If
necessary, call a fire department.

Automatic transmission fluid level
The transmission has a permanent fill of automatic
transmission fluid.
Regular automatic transmission fluid level checks and
changes are not required. For this reason the dipstick is
omitted.
If you notice f luid loss or gear shifting malfunctions,
have your authorized Mercedes-Benz Center check the
transmission fluid level.Checking engine oil level
SL 500
1Oil dipstick
2Oil filler cap
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.

1Oil dipstick
2Oil filler cap
Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.Oil level must be between the lower
(min) and upper (max) mark of the
dipstick.
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0l).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could
cause engine damage not covered by the Mercedes-Benz
Limited Warranty.
For low engine oil level warning, see page 210.

242 Towing the vehicle
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km/h). The key must be in steering lock position 2.
To be certain to avoid a possibility of damage to the
transmission, however, we recommend the drive shaft
be disconnected at the rear axle drive f lange for any
towing beyond a short tow to a nearby garage.
Do not tow with sling-type equipment. Towing with
sling-type equipment over bumpy roads will damage
radiator and supports.
The use of wheel lift equipment will damage engine oil
pan.
Important!
When towing the vehicle, please, note the following:
With the automatic central locking activated and the
key in steering lock position 2, 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.When transporting vehicle on flat bed equipment, the
front end of the vehicle must be loaded first. Additional
ramping may be required for loading to protect bumper
fascia.
Note:
To signal turns while being towed with hazard warning
flasher in use, turn key in steering lock to position 2 and
activate combination switch for left or right turn signal
in usual manner – only the selected turn signal will
operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.
Wa r n i n g !
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort in necessary to
brake and steer the vehicle.
