MERCEDES-BENZ SL65AMG 2007 R230 Owner's Manual

270 OperationDriving instructions
Coolant temperature
During severe operating conditions, e.g.
stop-and-go city traffic, the coolant tem-
perature may rise close to approx. 266°F
(130°C).
The engine should not be operated with
the coolant temperature over 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open at all times.
Warning!
G


Driving when your engine is badly over-
heated can cause some fluids, which
may have leaked into the engine com-
partment, to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it. Turn off the engine, get
out of the vehicle and do not stand near
the vehicle until the engine has cooled
down.

Turn off the engine

by turning the SmartKey to
position0. Remove the SmartKey
from the starter switch.


by pressing the KEYLESS-GO*
start/stop button. Open the driv-
er’s door (with the driver’s door
open, starter switch is in position 0,
same as SmartKey removed from
starter switch).

Open fuel filler flap 1 by pushing at
the point indicated by the arrow.
The fuel filler flap springs open.

Turn fuel cap 2 counterclockwise and
hold on to it until possible pressure is
released.

Take off fuel cap 2 and place it into
holder 3 located on the inside of the
fuel filler flap.

Only fill your tank until the filler nozzle
unit cuts out – do not top up or over-
fill.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact,
extinguish all smoking materials. Never
allow sparks, flame or smoking materials
near gasoline!
Turn off the engine before refueling.Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.


272 OperationAt the gas station
Insert fuel cap 2 into fuel filler neck
and turn fuel cap clockwise until it au-
dibly engages.

Close fuel filler flap 1.
You should hear the latch close shut.
Check regularly and before a long trip

Leaving the engine running and the fuel cap
open can cause the engine malfunction indicator
lamp ú (USA only) or the engine malfunction
indicator lamp ± (Canada only) to illuminate.
For more information, see the “Practical hints”
section (
page 336).
!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see the “Practi-
cal hints” section (
page 369).

274 OperationEngine compartmentHood
Opening
1Hood releaseWarning!
G
Do not pull the release lever while the vehi-
cle is in motion. Otherwise the hood could
be forced open by passing air flow.
This could cause the hood to come loose
and injure you and/or others.Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from the vehicle and do not open the
hood until the engine has cooled. If neces-
sary, call the fire department.
Warning!
G
You could be injured when the hood is open
– even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, only touch owner serviceable
components described in the Operator's
Manual and comply with all relevant safety
precautions.Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for ap-
proximately 30 seconds or may even restart
after the engine has been turned off. Stay
clear of fan blades.
Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition 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

275 Operation
Engine compartment

Pull hood release1.
The hood is unlocked.
2Lever for opening the hood

Push lever2 on the hood upwards.

Pull up on the hood and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts. Closing

Let the hood drop from a height of ap-
proximately 1
1/2ft (50 cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
!
To avoid damage to the windshield wipers or
hood, never open the hood if the wiper arms are
folded forward away from the windshield.
Warning!
G
When closing the hood, use extreme caution
not to catch hand or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged be-
fore driving. Do not continue driving if the
hood can no longer engage after an accident
for example. The hood could otherwise
come loose while the vehicle is in motion
and injure you and/or others.
i
Do not use any special lubricant additives,
as these may damage the drive assemblies. Us-
ing special additives not approved by
Mercedes-Benz may cause damage not covered
by the Mercedes-Benz Limited Warranty. More
information on this subject is available at any
Mercedes-Benz Center.
