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.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
The cruise control with a braking function 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 column. To keep the
specified speed constant, the system brakes if
the engine braking effect is not sufficient on a
downhill grade.
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, and loose road surface.
Otherwise you could lose control of the vehicle
and cause an accident.<

cruise control will, within limits, adjust your
vehicle's speed automatically so that you can
flow with the traffic without having to make con-
stant adjustments. If, for example, while cruis-
ing at the selected speed, you begin to
approach a slower vehicle ahead of you in the
same lane, the system will reduce your vehicle's
speed to the same as that of the vehicle ahead
to maintain your selected distance setting. You
can vary the following distance, which will vary
with speed. Based on your selected distance
setting, the system automatically decreases the
throttle setting and lightly applies the brakes if
necessary. In addition, if the vehicle ahead of
you slows to a complete stop, the system can
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 to which you
may be accustomed, 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 page73 to obtain a good command of the
system and its range of applications.
the brake pedal, a somewhat different braking
feel results.
Professional navigation system*
If the vehicle is equipped with a Professional
navigation system, the system adapts the
acceleration and deceleration behavior of the
vehicle to the road on which you are currently
driving.
To ensure that the system has the latest
information on the course of the road, use
the most recent version of the navigation
data.<
If the vehicle position is unknown, e. g. if you
have left the region covered by the map, the
navigation system ceases to influence vehicle
behavior.
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 con-
gestion. Do not use the system in city driving; in
complex driving situations; heavy traffic such as
during rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such as
highway off-ramps; during inclement weather
such as snow, strong rain or fog; or when enter-
ing 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

The selected distance is displayed in the instru-
ment panel.
Use good judgement 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 the system
Press the lever up or down and additionally
depress the brake if the vehicle is stationary.
The mark in the speedometer changes color
and the distance indicator goes out.
In addition, the system is interrupted:
>When the brakes are applied
>When transmission position D is disen-
gaged>When DTC is activated or DSC is deacti-
vated
>When DSC is activated
>When the safety belt is unbuckled and the
driver's door is opened while the vehicle is
stationary
>When the system has not detected objects
for an extended period, e. g. on a road with
very little traffic without road edge mark-
ings, or if the radar sensors are dirty, refer to
page72
If the system is interrupted, actively inter-
vene by braking and, if necessary, with
evasive maneuvers; otherwise, there is the dan-
ger of an accident occurring.<
Calling up the stored desired speed and
distance
While driving
Press button4, refer to page68.
All of the displays in the instrument panel lights
up.
While standing
Before leaving the vehicle with the engine
running, engage position P of the auto-
matic transmission and apply the parking brake.
Otherwise, the vehicle may begin to roll.<
If a vehicle detected ahead of you slows to a halt
and your vehicle is also brought to a halt by the
system:
>If the vehicle ahead of you drives away, your
vehicle accelerates automatically as long as
mark 1 for the desired speed in the speed-
ometer is green.
>If the vehicle ahead of you drives away when
mark 1 is orange, depress the accelerator
briefly or press button 4.
Rolling bars in the distance indicator 3
mean that the vehicle ahead of you has
driven away.
If you are standing behind a vehicle with your
brake pedal depressed and the system is deac-
tivated or interrupted: Distance 1, closest
Distance 2
Distance 3
Distance 4, furthest
This distance is set when you acti-
vate the system.

System limits
Speed range
Best results are achieved when using the sys-
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h and 110 mph/180 km/h.
The system can also be activated when station-
ary.
Comply with the legal speed limit in every situa-
tion when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited. For
instance, two-wheeled vehicles driving ahead
of you might not be detected.
Because of the limitations to the detec-
tion capacity of the system, you should be
alert at all times so that you can intervene
actively, if necessary; otherwise, there is the
danger of an accident occurring.<
Deceleration
The system does not decelerate when a sta-
tionary obstacle is located in the same lane, e.g.
a vehicle at a red traffic light or at the end of a
traffic congestion.
The system also does not respond to:
>Pedestrians or similarly slow road users.
>Red traffic lights.
>Stationary objects.
>Cross traffic.
>Approaching traffic.
A warning might not be issued when
approaching a stationary or very slow-
moving obstacle. Take action yourself, other-
wise there is a risk of an accident.<

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 if necessary. Be certain that floor mats 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 for large differences in
speed between your vehicle and the vehicle
ahead. Examples: 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.<
