ADAPTIVE CRUISE
CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control Buttons
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise
control while traveling on highways and
major roadways. However, it is not a safety
system and not designed to prevent colli
-
sions. Speed Control function performs differ -
ently. Please refer to the proper section within
this chapter.
ACC will allow you to keep cruise control
engaged in light to moderate traffic condi
-
tions without the constant need to reset your
cruise control. ACC utilizes a radar sensor
and a forward facing camera designed to
detect a vehicle directly ahead of you.
NOTE:

If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed set
speed.

If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accel
-
erate (not to exceed the original set speed)
automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.
The Cruise Control system has two control
modes:

Adaptive Cruise Control mode for main -
taining an appropriate distance between
vehicles.

Normal (Fixed Speed) Cruise Control mode
for cruising at a constant preset speed. For
additional information, refer to “Normal
(Fixed Speed) Cruise Control Mode” in
this section.
NOTE:
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware
of the mode selected.
You can change the mode by using the
Cruise Control buttons. The two control
modes function differently. Always confirm
which mode is selected.
1 — Adaptive Cruise Control On/Off Button
