ing distance without disengaging the cruise control.
The DIU will display the SmartCruise status screen
indicating the vehicle's current set cruise speed.
Once the speed of traffic ahead increases beyond
the adapted engine cruise speed, the original cruise
control set speed re-engages.
When SmartCruise is engaged, depressing the accel-
erator pedal will override the SmartCruise and will
cause the vehicle to accelerate. Depressing the
brake or clutch pedals will deactivate SmartCruise.
When approaching a slow moving or stopped vehicle
ahead, SmartCruise will attempt to maintain the mini-
mum following distance by reducing the engine
cruise speed and engaging the engine brake, if nec-
essary. If SmartCruise is unable to maintain the mini-
mum following distance, the driver will be alerted by
the CWS headway alerts until the driver takes control
or conditions clear.

Side Object Detection

The optional side object detection system may be
installed on one or both sides of the vehicle. The
radar sensor(s) are located on the side of the ve-
hicle, while the sensor display unit is mounted on the
A-pillar. See Fig. 2.49.
The side sensor display unit uses two lights to dis-
play the status of the side sensor(s). The yellow light
indicates the system is active, but no objects are de-
tected. The red light indicates that the side sensor
detects an object. If the vehicles turn signal is active
and the sensor detects an object alongside the ve-
hicle, an audible warning tone will sound.
