Programmable cruise control
The concept
The programmable cruise control is available
for use at speeds of approx. 20 mph/30 km/h
and higher. The vehicle maintains and stores
the speed that you set using the lever mounted
on the steering column.
You can also use the multilevel preset mode to
store six desired speeds for later selection with
the lever, refer to page67.
This feature assists you in quickly adapting the
vehicle speed to specific road conditions, e.g.
changes in speeds limits.
Do not use the programmable cruise con-
trol when unfavorable conditions do not
permit you to drive at a constant speed, e.g.
when driving on winding roads, in heavy traffic
or under poor road conditions such as snow,
rain, ice, or a loose road surface. If you do, you
could lose control of the vehicle and cause an
accident.<

Press lever to resistance point, arrow 1:
The system maintains and stores the current
vehicle speed. The pointer5 in the speedome-
ter indicates this speed, refer to Displays in
speedometer on page68. Each time the lever is
pressed again briefly, the speed is increased by
approx. 1 mph or 1 km/h.
Push the lever to the resistance point for a
longer time:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever past the resistance point if no
desired speeds6 are stored:
The pointer5 jumps to the next multiple of
5 mph or 10 km/h and then further, as long as
the lever is held. The speed then indicated is
reached and stored.
The vehicle may accelerate beyond the preset
speed on steep downhill stretches where the
engine's braking action alone may not be suffi-
cient to slow the vehicle. Speed can drop on
uphill grades if the engine output is insufficient.

Active cruise control*
The concept
With active cruise control you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control represents 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 tension, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
In addition to holding a steady cruising speed,
if you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that you can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising 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 between your vehicle and the
vehicle ahead. You can vary the distance, which
is additionally speed-dependent. Based on
your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, it may be necessary for the vehicle to
downshift to maintain 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 as needed. Your selected speed
will be maintained when driving downhill, too.
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 differ-
ently from conventional cruise control systems
to which you may be accustomed, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section begin-
ning on page73.<
Brake pedal feel
>When the system brakes and you also
depress the brake pedal, a somewhat differ-
ent braking feeling results.
>Any noises produced during automatic
braking are normal.
Applications
As with conventional cruise control systems,
active cruise control in no way diminishes or
substitutes for the driver's own personal
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. Do not use this system in city driving;
heavy traffic such as during rush hour; 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, 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 nec-
essary, especially when the system is actively

The selected distance is displayed in the
speedometer.
Distance 1
Distance 2
Distance 3
This distance is always set when
the system is used for the first time
after starting the engine.
Distance 4
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, a violation of the law or the danger of
an accident could result.<
Deactivating cruise control
Press the lever up or down. The displays in the
speedometer go out.
In addition, the system is automatically deacti-
vated:
>when the speed is reduced to below 20 mph
or 30 km/h due to a traffic situation
>when DTC is activated or DSC is deacti-
vated
>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 page72
>when you actuate the parking brake during
driving
>when you shift the transmission into the
Nposition
If the system is deactivated, then it is nec-
essary for the driver to actively intervene
by braking and possibly swerving. Otherwise,
there is the danger of an accident.<
Background lighting
You can switch off the backlighting of the
speedometer and tachometer when the system
is deactivated if no other functions are being
displayed, e.g. the pre-warning field in the
tachometer, refer to page75, or the route guid-
ance of the navigation system.
To do so, press the lever up or down for approx.
1second.

Warning lamps
The display flashes and a chime
sounds.
The system asks you to intervene
by braking or with an evasive
maneuver. The active cruise control cannot
automatically restore the distance to the vehicle
driving ahead.
The display does not relieve you of the respon-
sibility for adapting desired speed and driving
style to traffic conditions.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
actively intervene.
Radar sensor
Heavy rain and also dirt, snow, or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper.
When doing so, be particularly careful in remov-
ing layers of snow and ice.
If the sensor is not aligned properly, the active
cruise control cannot be activated.

Things to know about active cruise control
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; heavy traffic such as during rush
hour; 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 inter-
changes, 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, especially when
the system 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. 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 when approaching a traffic
light or 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. 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 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.<
When your vehicle is actively following a vehicle
in front of you, if the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane may also result in accelera-
tion of your vehicle.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling 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.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any deacti-
vation, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings.<

Driving
74 Active cruise control may brake when you
reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not
detect this vehicle until it is fully in your lane
ahead of your vehicle.
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 speed that is prudent in
view of the curves and terrain of the roadway.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
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with the system activated, resting your
foot on the accelerator pedal will cause the sys-
tem not to brake even if necessary. Be certain
that floormats or other objects on the vehicle
floor do not interfere 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.
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.<
