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.

Active cruise control may brake when you 
reduce the stored desired speed; however, 
the driver must constantly monitor traffic 
and intervene 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 
canceled. 
Behavior in curves 
Because of the limited range of the system, 
it is possible that in curves or on the peaks 
and valleys of hilly roads, a vehicle ahead 
may be recognized late, or not at all. There-
fore, 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 vehi-
cle decelerates in either case, you can 
choose to overcome the deceleration by 
briefly pressing the accelerator pedal. 
Driver interventions 
Remember actions by the driver 
always supersede and take priority 
over the system's automatic actions. Any-
time the driver presses down on the accel-
erator 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 con-
trols your cruising speed and distance set-
ting. While driving with activated system, 
resting your foot on the accelerator pedal 
will cause the system 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 system to apply the brakes is 
also limited, if you are driving down a steep 
grade or when you reduce your desired 
speed sharply. The system cannot stop 
your vehicle. It uses only a portion of brak-
ing 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: during emergency brak-
ing, 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.

Whenever active cruise control 
recognizes a situation that 
requires driver braking because 
the system capacity has been 
reached or has been exceeded, 
the system alerts the driver by flashing this 
symbol in the instrument cluster and 
sounding a chime.
