Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle- to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle. ■
Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations. “Radar Cruise Control Unavailable” will be displayed on the multi-information
display: ●
Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are no
vehicles ahead. ●
The preceding vehicle leaves the lane when your vehicle is following at a vehicle speed
below 25 mph (40 km/h). Otherwise, the se nsor can not properly detect the vehicle.●
VSC is activated. ●
TRAC is activated for a period of time. ●
When the VSC or TRAC system is turned off by pressing the VSC OFF switch. ●

NX300h_U_OM78007ULDA (Lane Departure Alert with steering control) While driving on a highway or freeway that has white (or yellow) lane markers
and few curves, a camera, which is located on the upper part of the windshield,
uses this system to recognize the white (yellow) lane markers and when the
driver has deviated from the lane. If the system judges that the vehicle has devi-
ated from the current traffic lane, along with alerting the driver with a buzzer and
indications in the multi-information display, it will provide assistance by operating
the steering wheel to avoid further deviation from the marker lines.
