Important safety notes You can use the HomeLink
®
garage door
opener integrated

into the rear-view mirror to
operate up to three different gate/garage
door opener systems. i
Certain garage door drives are
incompatible with the integrated garage
door opener. If you have difficulty
programming the integrated garage door

WARNING
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a

garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),
and inhaling it can cause unconsciousness
and possible death. All exhaust gas contains

Hood
Opening the hood G
WARNING
Do
not pull the release lever while the vehicle
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. G
WARNING
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department. G
WARNING
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,

let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G
WARNING
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
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades. G
WARNING
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:
R with the engine running
R while starting the engine
R when the ignition is switched on and the
engine is turned manually

Notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qts
(0.8 l) of oil over
a distance of 600 miles (1,000 km). The oil
consumption may be higher than this when
the

vehicle is new or if you frequently drive at
high engine speeds.
Checking the oil level using the oil
dipstick On the G 55 AMG, the oil level can be checked
using the on-board computer.
When checking the oil level:
R
park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature

(i.e. if you only start

Turn the SmartKey to position
2(Y page 115) in the ignition lock.
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †). G
WARNING
In order to avoid any potentially serious burns:
R 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 display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. X
Slowly turn cap : half a turn
counterclockwise and allow excess
pressure to escape.
X Turn cap : further counterclockwise and
remove it.
If the coolant is at the level of marker bar
= in the filler neck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant is approximately 0.6 in
(1.5 cm) above marker bar = in the filler
neck when warm, there is enough coolant
in coolant expansion tank ;.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap : and

turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 276).

flammable. Do not spill washer solvent/
antifreeze on

hot engine parts, because it may
ignite and burn. You could be seriously
burned.
