setting: P. 2 6 2
■Dynamic radar cruise control with full-speed range can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following
situations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are
no vehicle ahead.
●The preceding vehicle leaves the lane when your vehicle is following at a speed
below 25 mph (40 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turn ed off by pressing the VSC OFF switch.
●The sensor cannot operate correctly because it is covered in some way.

Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping, indi cations on the multi-information dis-
play, and a sensory warning* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the
center of the lane.
Lane keeping assist function• This function will be active when the vehicle-to -vehicle distance con-
trol mode of the dynamic radar crui se control with full-speed range
(  P. 257) is set with vehicle sp eed above approximately 45 mph
(72 km/h) and while the lane depa rture warning function is active.
• When the lane keeping assist fu nction is active, a slight steering
torque will be applied, to help the driver maintain the vehicle inside
the lane.
The lane keeping assist function will be temporarily canceled if the steering
wheel is not operated, or if you continue driving with your hands lightly touch-
ing the steering wheel. ( P. 2 7 8 )
