Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
R Check the transmitter frequency used by
garage door drive remote control 0083and
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door
remote control 0083. This increases the like-
lihood that garage door remote control 0083
will transmit a strong and precise signal to
the integrated garage door opener.
R When programming, hold remote control
0083 at varying distances and angles from the
button which you are programming. Try var- ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
R If another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control 0083.
R Note that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press button 0084on remote control 0083again
before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-tion/transmission. Opening/closing the garage door After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control.
Please also read the operating instructions
for the garage door system.

Hood
Important safety notes G
WARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. G
WARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement. G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING

and must be accurate at all times. Engine oil
General notes G
WARNING
Hybrid vehicles: be sure to read the "HYBRID" supplement. Otherwise, you could fail to rec-
ognize dangers.
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.
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 if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait about 30 minutes
before carrying out the measurement. Engine compartment

little energy, thus conserving battery
power.
Charging the battery
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with water and seek medical attention. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (Y page 353).
X Open the hood.
X Connect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor bat-
tery in the jump-starting procedure
(Y page 353). If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the dis-
charged battery has frozen. In this case, you
may neither charge the battery nor jump-start
the vehicle. The service life of a thawed-out
battery may be shorter. The starting charac-
teristics may be impaired, especially at low
temperatures. Have the thawed-out battery
checked at a qualified specialist workshop.
Never charge a battery still installed in the
vehicle unless a battery charger unit
approved by Mercedes-Benz is being used. A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an accessory. It permits the charging of the bat-
tery in its installed position. Contact an
authorized Mercedes-Benz Center for further information and availability. Read the batterycharger's operating instructions before
charging the battery. 352
Battery (vehicle)Roadside Assistance

Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jumper
cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
R Vehicles with a gasoline engine: only jump-start the vehicle when the engine and exhaust
system are cold.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Only jump-start from batteries with a 12 V voltage rating.
R Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the battery slightly.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
R the jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
X Apply the parking brake firmly.
X Shift the transmission to position P.
X Switch off all electrical consumers, e.g. rear window defroster, lighting, etc.
