Stationary or Very Slow-Moving Objects
CAUTION:
{
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash
into an object ahead of you. Do not use
Adaptive Cruise Control when approaching
stationary or slow-moving vehicles or other
objects.
CAUTION:
{
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. Your vehicle may
accelerate toward objects, such as a stopped
vehicle that suddenly appears after the lead
vehicle changes lanes. Your complete attention
is always required while driving and you should
be ready to take action and apply the brakes.
Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control
begins to disengage. The driver alert symbol on
the HUD flashes and the warning beep sounds.
The driver must take action since Adaptive Cruise
Control will not slow the vehicle to a stop.
Passing a Vehicle
To increase speed to pass a vehicle, use the accelerator
pedal. While your foot is on the accelerator pedal,
the system will not automatically apply the brakes.
Once you pass the vehicle and remove your foot from
the accelerator pedal, Adaptive Cruise Control returns
to normal operation and the brakes can be applied,
if needed.
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.
