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 system 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 
deactivated whenever the driver applies 
the vehicle brakes, shifts the transmission 
from drive/D to neutral/N, or deactivates 
DSC. After any deactivation, the system 
will no longer automatically activate the 
vehicle brakes, which means the driver 
must intervene and resume manual 
braking. 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 
vehicle decelerates in either case, you can 
choose to overcome the deceleration 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 dis-
tance setting. 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
