Active Cruise Control
The concept
With Active Cruise Cont rol, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a select ed distance set-
ting as slower traffic is encountered.
Active Cruise Control is a technological
advance over the familiar cruise control and is a
welcome relief from the constant adjustment of
speed that can accompany driving in traffic on
highways or other high-speed thoroughfares.
Especially on longer trips, the system can
reduce fatigue and tens ion, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
Within the limits of its capability, the system
automatically adapts the ca r's speed to that of a
slower vehicle in front of you. You can specify
the distance to be main tained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-depe ndent. Based on your
selected distance setting, the system automat-
ically decreases the thro ttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automati cally illuminate to sig-
nal a following driver to take action. In addition,
it may be necessary for the vehicle or the driver
to downshift, depending on the kind of trans-

mission your vehicle is equipped with, to main-
tain the distance setting
selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehi cle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this Active Cruise Control system is a
new technology and operates differently from
conventional cruise co ntrol systems which you
may be accustomed to, you are strongly urged
to read all of the pages relating to this system
before use. Pay special attention to the System
limitations section beginning on page 81.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, peda l sensation will be
slightly different from the usual.
> Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110 mph or 180 km/h.
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 wh ere traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush hour; on curvy, winding ro
ads, 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 inter-
changes, service/parkin g areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setti ng within applicable
legal limits. Always be re ady to take action or
apply the brakes if necessary, especially when
the system is actively fo llowing a vehicle in front
of you. Otherwise, driving situations could
result that pose the risk of accidents. <

System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle, or stationary object ahead
of you, for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. The system may also not detect
smaller moving objects such as motorcycles or
bicycles. Be especially alert when encountering
any of these situations as the system will nei-
ther automatically 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. <
Active Cruise Control is not and must not
be used as a collision avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactiva te the system when
you pull into an exit lane for a highway off-
ramp. < Also, vehicles travelin
g in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
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
system to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
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. <
Active Cruise Control ca n only decelerate the
vehicle to approx. 20 mph or 30 km/h.

ControlsDriving
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, Active Cruise Control will not
recognize this vehicle until it is fully in your lane
ahead of your vehicle.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to maintain the selected distance automatically.
This also applies to gr eat differences in speed
between you and vehicles ahead, e.g. when
quickly approaching a truc k. There is a risk of
collision. Once the system has established that
a vehicle is indeed in fron t of you, it will indicate
that you must brake and/or maneuver the vehi-
cle yourself. Take action yourself; otherwise,
there is a risk of an accident. <
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a sp eed that is prudent in
view of the curves and terrain of the roadway. In approaching a curve, it is possible that Active
Cruise Control wo
uld react briefly to a vehicle in
the adjacent lane. In a ddition, 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.
Your responsibility
Your actions have priority at all times. When you
press the accelerator pedal while driving with
Active Cruise Control, the automatic braking
function will be temporar ily interrupted. Once
you release the accelera tor pedal, the desired
speed or the selected distance to the vehicle
ahead is achieved again.
Do not leave your foot on the accelerator
pedal and make sure that no objects such
as floor mats are lying on the accelerator pedal.
Otherwise, the system may not be able to brake
the vehicle.<
