The red coolant warn-
ing lamp comes on
while the engine is run-
ning. A warning tone
also sounds.The coolant temperature has exceeded 248 ‡ (120 †). The air-
flow to the engine radiator may be blocked or the coolant level may
be too low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury.

When indicator lamp :lights up green:
programing is finished.
When indicator lamp :flashes green: pro-
graming was successful. The next step is to
synchronize the rolling code.
XRelease button Bof remote control Aof
the garage door drive.
If indicator lamp :lights up red: repeat the
programing process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote con-
trol Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Problems when programing
If you experience problems programing the
integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote control Aand
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.
RReplace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to the integrated garage door opener.
RWhen programing, hold remote control A
at varying distances and angles from the
button which you are programing. Try vari-
ous angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control is available for the
same garage door drive, repeat the same
programing steps with this remote control. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control A.
RNote that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press buttonBon remote control Aagain
before transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

Engine compartment
Hood
Important safety notes
GWARNING
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. Before
every trip, ensure that the hood is locked.
GWARNING
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.
GWARNING
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.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
Opening the hood
GWARNING
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 with a little more force.
Engine oil
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.
When checking the oil level:
Rpark the vehicle on a level surface.
Rthe engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
Rif 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.

The jump-starting connection point is in the
engine compartment.
If the indicator/warning lamps do not light up
at low temperatures, it is very likely that the
discharged 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 char-
acteristics can be impaired, particularly at
low temperatures. Have the thawed-out bat-
tery checked at a qualified specialist work-
shop.
Read the battery charger's operating instruc-
tions before charging the battery.
XOpen the hood.
XConnect 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
(
Ypage 559).
558Battery (vehicle)
Breakdown 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:
RThe 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.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf 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.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
RBare parts of the terminal clamp do not come into contact with other metal parts while the
jumper cables are connected to the battery.
Rthe 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.
XSecure the vehicle by applying the electric parking brake.
XShift the transmission to position P.
XTurn the SmartKey to position 0in the ignition lock and remove it (Ypage 151). On vehicles
with KEYLESS-GO, make sure the ignition is switched off (
Ypage 152). All indicator lamps
in the instrument cluster must be off.
XSwitch off all electrical consumers, e.g. rear window defroster, lighting, etc.
XOpen the hood.
