SmartCruise
The “RANGE” control knob (see Figure 2, page 4), adjusts the SmartCruise
“following distance”.
Listed below are descriptions of the most common situations encountered
while using SmartCruise.
•
Cruise On and No Vehicle Detected
If no vehicle is present within the range of the VORAD radar,
SmartCruise is not active and normal cruise control perfor-
mance is maintained.
•
Cruise On and Vehicle Detected - SmartCruise becomes active
As the VORAD-equipped vehicle approaches a slower moving
vehicle in the same lane, the VORAD-equipped vehicle will slow
to the speed of the other vehicle and speed match to maintain
the set following interval. The speed reduction may be accom-
plished by the engine ECM (Engine Control Module) issuing a
command to reduce fuel and engaging the engine retarder, if
necessary. The driver can adjust the SmartCruise following
interval from 2 to 3 seconds by using the range / distance knob.
SmartCruise does not replace an alert driver. SmartCruise will not react to
stationary objects and cannot bring the vehicle to a complete stop. The
driver still needs to use good driving practices to avoid an accident.
If the host vehicle speed and the target vehicle speed are drastically differ-
ent, the driver may need to apply brakes to maintain a safe distance. As
with cruise control, SmartCruise must be reset after brakes have been
applied.
