CAUTION:
{
If you rest your foot on the accelerator pedal,
the system will not automatically apply the
brakes. You could crash into a vehicle ahead
of you. Do not rest your foot on the accelerator
pedal when using Adaptive Cruise Control.
Curves in the Road
CAUTION:
{
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle
in your lane. You could crash into a vehicle
ahead of you, or lose control of your vehicle.
Give extra attention in curves and be ready
to use the brakes if necessary. Select an
appropriate speed while driving in curves.
Adaptive Cruise Control may operate differently in a
sharp curve. It may reduce your speed if the curve
is too sharp.
When following a vehicle and entering a curve,
Adaptive Cruise Control could lose track of the vehicle
in your lane and accelerate your vehicle. When this
happens the Vehicle Ahead symbol will not appear.
