The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The system
automatically switches between high beams
and low beams, reacting to oncoming traffic,
vehicles ahead of you, and sufficiently lit areas,
e.g. in built-up zones.
Manually switching between high
beams and low beams
If you wish or the situation requires, you can
intervene at any time.
>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horsedrawn vehicles, railroad
or shipping traffic close to the road, and at
deer crossings
>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of highly reflective signs
>in the low speed range
>when the windshield is fogged up, dirty or
covered with stickers, decals etc. in the area
of the inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.

What to do if …
What to do if …
>a navigation DVD is inserted, but an instruc-
tion to insert the DVD appears on the Con-
trol Display?
The navigation DVD may not be the correct
DVD for the navigation system. This infor-
mation is indicated on the DVD label.
>you request the current position of your
vehicle, but do not receive a precise dis-
play?
The system is unable to receive enough
GPS signals at your current position due to
obstructions, your position is not yet avail-
able on your navigation DVD, or the system
is in the process of calculating your posi-
tion. Reception is best when you have an
unobstructed view to the sky.
>the destination guidance does not accept a
destination?
The data of the destination is not stored on
the navigation DVD that is loaded. Select a
destination that is as close as possible to
the original.
>the destination guidance does not accept
an address without the street name?
On the navigation DVD, no downtown area
can be determined for the city or town
entered. Enter any street, or a destination
such as the railway station in the selected
town, and then start the destination guid-
ance.
>you want to enter a destination for the des-
tination guidance, but it is not possible to
select the letters for your desired entry?
The data of the destination is not stored on
the navigation DVD that is loaded. In this
case, the system will not offer you any let-
ters to choose from. Select a destination
that is as close as possible to the original.>the system stops furnishing directions on
which way to turn as you approach intersec-
tions?
You are driving in an area that has not yet
been completely recorded on the naviga-
tion DVD. Instead of an arrow indicating a
turn, you will see an arrow which indicates
the general direction of your planned route.
Or you have left the recommended route
and the system requires a few seconds to
calculate a new recommended route.
>the navigation system does not react to
entries?
If the battery was disconnected, it takes
about 10 minutes before the system is once
again operational.

Weather news flashes*
Weather Radio is a service of the National Oce-
anic and Atmospheric Administration (NOAA)
of the US Department of Trade. Weather news
flashes are repeated every 4 to 6 minutes and
are routinely updated at intervals of 1 to
3 hours, and more often when necessary. Most
stations operate 24 hours a day. In case of a
storm, the National Weather Service interrupts
the routine weather news and transmits special
warning messages instead. If you have a ques-
tion about NOAA Weather Radio, please con-
tact the nearest office of the National Weather
Service. Details are also provided on the Inter-
net at www.nws.noaa.gov.

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The oil level can be displayed when the engine
is at operating temperature. Constant short-
distance driving or a very sporty driving style
can make it impossible for a measurement to be
taken.
Displays in instrument cluster
You can display the current oil level in the
instrument cluster.

2Maximum marking
3Minimum marking
4BC button
Press the button4 in the turn signal lever
repeatedly until the display for the oil level
appears in the instrument cluster.
Manual transmission: the engine oil level
will be shown in the lower display.<
The oil level must be between the two marks.
A new measurement is automatically taken
after each engine start.
Possible displays
1Oil level OK
2Oil level is being determined.
This process takes about 1 minute when
stopped on a level surface.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
3Oil level at minimum:
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below Add at least
0.5 US quart/0.5 liter. Otherwise the oil
level control may not display the new value
correctly.
If the oil level displayed is below minimum,
add engine oil immediately. Failure to do so
may lead to engine damage.
4Oil level too high
Have the vehicle checked immedi-
ately, otherwise engine damage may
result if too much oil has been added.<
5No value can be determined at this time.
Engine is not yet at operating temperature.

Fast measurement
In addition to the automatic measurement, you
can also determine the current oil level manu-
ally, e.g. after adding engine oil, but with a lower
degree of measuring accuracy.
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button on the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button for at least 2 seconds.
The oil level is determined. A clock symbol
is displayed during the measurement.
5.After approx. 1 minute the current oil level is
displayed.
