objects for a longer period of time, e.g. on
infrequently traveled roads without a shoul-
der or guard rails, or if the radar sensor is

When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary, otherwise there is a
risk of accident.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated due to one of
the following factors: you are driving under a
speed of 20 mph or 30 km/h, the handbrake is
applied, or DSC is intervening. A message
appears on the Control Display.
Resuming stored desired speed and
distance
Press button 4.
The stored speed and distance are regained
and maintained.
In the following instances, the stored speed is
deleted and can no longer be resumed:
>When driving control systems are interven-
ing
>In cars with manual transmission: when you
shift gears very slowly or engage neutral
gear
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off

The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to
the vehicle ahead.
This indicator does not release you, however,
from your responsibility to adapt your desired
speed and driving style to prevailing driving
conditions.

interventions. Active cruise control is deacti-
vated. You can reactivate the system, if desired,
by tapping or pulling the lever when road and
traffic conditions permit this. It is not possible to
resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt, snow or ice. If necessary, clean the radar sensor
located in the front bumper, see arrow. Be sure

of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page73.
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, as for example, at 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 motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem 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 alert-
ness.<
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 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

Driving
62 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 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.<
Active cruise control can only decelerate the
vehicle to approx. 20 mph or 30 km/h.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize 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 great differences in speed
between you and vehicles ahead, e.g. when
quickly approaching a truck. There is a risk of
collision. Once the system has established that
a vehicle is indeed in front of you, it will indicate
that you must brake and/or maneuver the vehi-cle yourself. Take action yourself, as there is
otherwise a risk of 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 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 would 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.
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 temporarily interrupted. Once
you release the accelerator 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

Otherwise the system may not be able to brake
the vehicle.<

on page168.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message will appear on the Control Dis-
play for a short time and the cruising range for
the remaining amount of fuel is displayed on the
computer. Under a cruising range of approx.
30 miles/50 km, the message remains in the
Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, as otherwise engine functions are not
ensured and damage can occur.<
