Do not use washing mechanisms when
the washer fluid reservoir is empty, other-
wise you will damage the washer pump.<
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
Only add washer fluid with the engine
cooled down to exclude contact with hot
engine components. Otherwise there is a dan-
ger of fire and to personal safety if the fluid is
spilled.<
All washer nozzles are supplied from one reser-
voir.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix
the washer fluid before filling.<

Cruise control*
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn. To maintain the specified speed, the sys-
tem brakes if the engine braking effect is not
sufficient on a downhill grade. Speed can drop
on uphill grades if the engine output is insuffi-
cient.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g., when driving on winding
roads, in heavy traffic or in poor road conditions
such as snow, rain, ice, lose road surface, and
poor visibility. Otherwise you could loose con-
trol of the vehicle and cause an accident.<

follow this action within the given scope and
can also accelerate from a complete stop if the
vehicle ahead of you drives off again shortly
thereafter. During braking, your vehicle brake
lamps will automatically illuminate to alert a fol-
lowing driver to take action. In addition, it may
be necessary for your vehicle to downshift the
automatic transmission to maintain the dis-
tance setting selected. As soon as the road in
front of you has no moving vehicles, the system
will accelerate to your desired speed. This set
speed is also maintained on downhill grades,
however the vehicle speed can drop below the
set speed when driving uphill if the engine out-
put is not sufficient.
Active cruise control cannot detect stop
signs, red lights, or any object that is
stopped or is blocking the road.
Active cruise control is not and must not be
used as a collision avoidance/warning system.
Since this active cruise control system is a new
technology and operates differently from con-
ventional cruise control systems which you may
be accustomed to, it is necessary that you read
all of the pages relating to this system before
use. Carefully read and observe the information
on the system limitations beginning on page71
to obtain a good command of the system and its
range of applications.<
Brake pedal feel
When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.
Professional* navigation system
If a navigation DVD is in the drive, refer to
page132, within limits the system adjusts the
accelerating and braking behavior of the vehicle
to the road you are driving on.
To ensure that the system is informed of
the current course of the road, always use
the latest navigation DVD if possible.<
When the vehicle position is unknown, e. g.
when you leave the map area, this influence of
the navigation system is not available.
Applications
Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it
during normal traffic.
As with conventional cruise control systems,
active cruise control in no way reduces or sub-
stitutes for the driver's own personal experi-
ence, responsibility, alertness and awareness in
adjusting speed, braking or otherwise control-
ling the vehicle. The driver should decide when
to use the system on the basis of road, traffic,
visibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly as well as in slow-moving traffic. Do
not use the system in city driving; in complex
driving situations; heavy traffic such as during
rush hour; on curvy, winding roads, slippery
roads or roads with sharp curves such as high-
way off-ramps; during inclement weather such
as snow, strong rain or fog; or when entering
interchanges, service/parking areas or toll
booths. It is also important to regulate your
vehicle's speed and distance setting within
applicable legal limits. Always be ready to take
action or apply the brakes if necessary, espe-
cially when the system is actively following a
vehicle in front of you. Otherwise, driving condi-
tions can result which lead to a violation of the
law or elevated risk of an accident.
The minimum initial activation speed is 20 mph/
30 km/h, and the maximum speed is 110 mph/
180 km/h. However, you can also activate the
system while stopped, refer to While stopped,
page69.

Use good judgment to select the appro-
priate following distance, given road con-
ditions, traffic, applicable laws and state driving
recommendations for safe following distance.
Otherwise, a violation of the law or risk of an
accident could result.<
Interrupting cruise control
Press the lever upward or downward, and with
the vehicle stopped also depress the brake
pedal. The marking in the speedometer
changes color and the distance indicator goes
out.
In addition, the system is automatically inter-
rupted:
>when you apply the vehicle brakes
>when you shift the transmission
>when DTC is activated or DSC is deacti-
vated
>when DSC comes on
>when you apply the parking brake
>when you release the safety belt and open
the driver's door with the vehicle stopped
>when the system does not recognize any
objects for an extended period of time, e. g.
on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page70
If the system is interrupted, then it is nec-
essary for the driver to actively intervene
by braking and steering. Otherwise, there is a
risk of an accident.<
Resuming stored desired speed and
distance
While driving
Press button4.
The displays appear in the instrument cluster.
While stopped
Before leaving the vehicle with the engine
running, engage position P of the auto-
matic transmission and apply the parking brake.
Otherwise the vehicle can roll.<
If a detected vehicle in front of you brakes to a
complete stop and your vehicle has also been
braked to a complete stop by the system:
>If the vehicle in front of you drives off while
the marking1 for the desired speed in the
speedometer is green, your vehicle will
accelerate without you having to do any-
thing.
>If the vehicle in front of you drives off while
the marking1 is orange, you briefly depress
the accelerator pedal or press button4.
Rolling bars in the distance indicator3
mean that the vehicle in front of you has
driven off.
If you are stopped behind a vehicle with the
brake pedal depressed and the system is inter-
rupted or deactivated:
1.Press button4 to activate a stored desired
speed or select a desired speed with the
lever, arrow1 or arrow2.
2.Release the brake pedal.
3.If the vehicle in front of you drives off, briefly
depress the accelerator pedal or press
button4.
Deactivating system
>Press the lever upward or downward twice
while driving.
>When stopped, do the same with the brake
pedal depressed.
>Switch off the ignition.
The displays turn off, and the stored desired
speed and distance are deleted.

System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; in complex driving situations; on
curvy, winding roads, slippery roads or roads
with sharp curves such as highway off-ramps;
during inclement weather such as snow, strong
rain or fog; or when entering interchanges, ser-
vice/parking areas or toll booths. It is also
important to regulate your vehicle's speed and
distance setting within applicable legal limits.
Always be ready to take action or apply the
brakes if necessary, especially when the sys-
tem is actively following a vehicle in front of
you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic,
pedestrians or other types of potential traffic
such as a rider on horseback. It is also possible
that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<
The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g., on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's

In approaching a curve, it is possible that active
cruise control might react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Driver interventions and your
responsibility
Anytime the driver presses down on the
accelerator pedal, any braking action by
the system is interrupted and the distance indi-
cator goes out until the pedal is fully released.
As soon as you fully release the accelerator, the
system will again control your cruising speed
and distance setting. While driving with the sys-
tem activated, resting your foot on the acceler-
ator pedal will cause the system not to brake
even when necessary. Be certain that floormats
or other objects on the vehicle floor do not inter-
fere with movement of the accelerator pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e. g.
when you reduce your desired speed sharply. It
uses only a portion of braking system capacity
and does not utilize the full capacity of the vehi-
cle braking system. Therefore, the system can-
not decrease your speed due to large differ-
ences in speed between your vehicle and the
vehicle ahead. Example: when you approach a
vehicle traveling at a much lower speed than
your own speed such as approaching a toll
booth or when a much slower vehicle cuts in
front of you at close range.<
