Limitations of the system
The smart cruise control system may
have limits to its ability to detect dis-
tance to the vehicle ahead due to
road and traffic conditions.
On curves
On curves, the smart cruise control
system may not immediately
detect a moving vehicle in your
lane, and then your vehicle could
accelerate to the set speed. Also,
the vehicle speed will rapidly
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on curves and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road and driving conditions ahead. Your vehicle speed can be reduced
due to a vehicle in the adjacent
lane. Adjust your vehicle speed by
depressing the brake pedal
according to the road and driving
conditions ahead. Apply the accel-
erator pedal and select the appro-
priate set speed. Check to be sure
that the road conditions permit safe
operation of the smart cruise con-
trol.

Driving your vehicle
On inclines
During uphill or downhill driving,the smart cruise control system
may not immediately detect a mov-
ing vehicle in your lane, and may
cause your vehicle to accelerate to
the set speed. Also, the vehicle
speed will rapidly down when the
vehicle ahead is recognized sud-
denly.
Select the appropriate set speed on inclines and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road and driving conditions ahead.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme- diately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a vehicle which moves into your lane is slower than your vehicle,
your speed may decrease to main-
tain the distance to the vehicle
ahead. If a vehicle which moves into your
lane is faster than your vehicle,
your vehicle will accelerate to the
selected speed.
