Approaching and Following a Vehicle
If this symbol does not appear, or disappears briefly,
Adaptive Cruise Control will not respond to vehicles
you may see ahead.
CAUTION:
{
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
"Cleaning the System" later in this section.
3-22
The vehicle ahead symbol
will only appear on the
HUD when a vehicle ahead
is detected in your path.
Adaptive Cruise Control will automatically slow your
vehicle down when approaching a slower moving vehicle.
It will then adjust your speed to follow the vehicle in front
at the selected follow distance. Your speed will increase
or decrease to follow the vehicle in front of you but will not
exceed the set speed. The system may apply limited
braking if necessary. When braking is active, your brake
lights will come on. It may feel or sound different than if
you were applying the brakes yourself. This is normal.
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.
