General notes The HomeLink
®
garage door opener integrated
in the rear-view mirror allows you to operate up
to three different door and gate systems.
Use the integrated garage door opener only on
garage doors that:
R they are equipped with a safety stop and
reverse feature
R they conform to the current U.S. safety stand-
ards
When it has been programmed, the integrated
garage door opener in the rear-view mirror will
assume the function of the garage door sys-
tem's remote control. Please also read the oper-
ating instructions for the garage door system.
When programming a garage door opener, park the vehicle outside the garage. Do not leave the
engine running while programming it.
Certain garage door drives are incompatible
with the integrated garage door opener. If you
have difficulty programing the integrated garage
door opener, contact a Mercedes-Benz Service
Center.
Alternatively, you can call the following tele-
phone assistance services:

Important safety notes G
WARNING
When you operate or program the door with
the integrated garage door opener, persons in the range of movement of the door may
become trapped or be struck by the door.
There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the door. G

Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and can result in poisoning. There is a risk of
fatal injury. Therefore, never leave the engine running an enclosed space without adequate
ventilation.

Notes on the oil level Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
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.
Depending on the engine, the oil dipstick may be in a different location.
It is only possible to correctly measure the oil
level when:
R the engine is at normal operating temperature
R the vehicle is parked on a level surface
R the engine is left running in neutral for at least
30 seconds before switching off
This applies when checking the oil level using
the oil dipstick or on-board computer.
Checking the oil level using the oil dip-
stick G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
It is only possible to correctly measure the oil
level with the oil dipstick when the engine is at
normal operating temperature and in a period of 2 to minutes after the engine has been switchedoff. 236
