SmartCruise (Optional)
Cut In and Out
If the speed of the target vehicle is faster than that of the host vehicle, the host
will continue to maintain its speed. However, if the speed of the target vehicle
is less than the host’s speed, the engine ECM will issue a command to reduce
fuel and may also engage the engine retarder. Once the target vehicle moves
out of the hosts lane, the host will restore the cruise control speed or resume
the following interval if another target vehicle is in the lane. Again, the driver
may need to apply the service brake to maintain a safe distance. The driver
may also depress the acceleration pedal at any time to override SmartCruise.
Cut in and Stay
If a target vehicle in an adjacent lane cuts in front of the host vehicle and
remains there, the system will respond by slowing the host to restore the set
following interval to the target vehicle. The engine ECM will reduce fuel and
may also engage the engine retarder to accomplish this. Again, the driver may
need to apply the brake to maintain a safe distance.
Vehicle Ahead Changes Lane
When maintaining a following interval to a target vehicle in front, and that
vehicle moves into an adjacent lane, the system will respond. If there is no
other vehicle ahead (or within the range of the system), the host will acceler-
ate to the set cruise speed. If there is another vehicle ahead, the host vehicle
will restore the following interval to that vehicle. Again, the driver may need to
apply the brake to maintain a safe distance.
SmartCruise and AutoShift™ Transmissions
Under any situation that causes the system to slow the vehicle, and the engine
RPM reaches a preset minimum, the AutoShift will automatically downshift.
Similarly, any situation that causes the vehicle to accelerate and a preset max-
imum engine RPM is reached, the AutoShift will upshift.
SmartCruise and Manual Transmissions
Under any situation that causes the system to slow the vehicle, and the engine
rpm reaches a preset minimum, the engine ECM will disengage cruise control
and the driver may need to manually downshift the transmission. If this hap-
pens, the vehicle cruise control will need to be re-engaged (Resume or Set)
before SmartCruise will be operational again.
