To cl os e:
Lower hood and let it drop into lock from a height of
a pprox. 1 f t. (30 cm), assisting w it h h ands pla ced f la t 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 wh en t he hood is open and th e 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.

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

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.

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 qu antity b etween u pper a nd l ower dipstick m arking
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

Adding coolant
If coolant has to be add ed, a 50/50 mix ture of water and
MB anticorrosion/antifreeze should be added.
Model SL 500
The drain plugs for the cooling system are located on
the right side of the engine block and at the bottom of
the radiator.
Model SL 600
The drain plugs for the cooling system are located on
the right and left sides of the engine block and at the
bottom of the radiator.
Anticorrosion/antifreeze, see coolants on page 280.
Wa r n i n g !
In order to avoid possible serious burns or injury:
• Use extreme caution when opening the hood if
there are any signs of steam or coolant leaking
from the cooling system, or if the coolant
temperature gauge indicates that the engine is
overheated.• Do not remove pressure cap on coolant
reservoir if engine temperature is above 194°F
(90°C). Allow engine to cool down before
removing cap. The coolant reservoir contains
hot fluid and is under pressure.• Using a rag, slowly open cap approximately 1/2
turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.• Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine
parts.

Changing wheelsMove vehicle to a level area which is a safe distance
from the roadway.
1. Firmly set parking brake, raise roll bar, and turn on
hazard warning f lasher.
2. Move selector lever to position “P”.
3. While engine is running, depress wheel change
switch for level control. The indicator lamp in the

up.
4. Turn off engine.
5. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axl e. On a l evel road, pl ace one ch ock in front of a nd
one behind the wheel that is diagonally opposite to
the wheel being changed.
The jack is designed exclusively for jacking up the
veh icle at the jack tu bes bui lt into eith er si de of th e
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by th e jack. Keep hands and feet away from the area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parking brake whi le th e vehic le is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.Before working on the vehicle, e.g. when changing
wheels, the roll bar should be raised with the
switch, and the key be removed from the steering
lock, to prevent possible injury.

8. Insert jack arm fully into the tube hole up to the
stop. Place jack on firm ground. Position the jack so
that it is always vertical (plumb-line) as seen from
the side (see arrow), especially if the vehicle is
parked on an incline.
9. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.
10. Unscrew upper-most wheel bolt and install
alignment bolt (1) supplied in the tool kit. Remove
the remaining bolts. Keep bolt threads protected
from dirt and sand.11. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.
12. Clean contact surfaces of wheel and wheel hub.
Install spare wheel on wheel hub. Insert wheel bolts
and tighten them slightly.
To avoid paint damage, place wheel f lat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last
wheel bolt.

Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the trunk
behind the right side cover panel.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.Therefore, we strongly recom mend that you h ave the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for sh ort di stance trips, or if it is not u sed for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components will be
damaged.
Important!
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries w hile connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
cloth ing. In c ase it does, imm edi ately f lu sh af fec ted
area with water and seek medical help.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.
