HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to adjust
the speed of your vehicle to maintain a set
gap from the vehicle in front of you in the
same lane while following it to a complete
stop. You can also engage the system to
follow a vehicle in front of you and adjust
set speed while stopped.
WHAT IS ADAPTIVE CRUISE
CONTROL WITH LANE
CENTERING
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the lane by applying
continuous assistance steering torque
input toward the lane center on highways.
Note:
The adaptive cruise control gap
setting operates normally.
WHAT IS INTELLIGENT
ADAPTIVE CRUISE CONTROL
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. For
example, if the speed sign recognition
system detects a 50 mph (80 km/h)
speed limit, the cruise set speed is updated
to
50 mph (80 km/h).
Note: The adaptive cruise control gap
setting operates normally. ADAPTIVE CRUISE CONTROL
PRECAUTIONS - VEHICLES

Evasive Steering Assist (If Equipped)
If your vehicle is rapidly approaching a
stationary vehicle or a vehicle traveling in
the same direction as your vehicle, the
system is designed to help you steer
around the vehicle.
The system only activates when all of the
following occur:
• The Pre-Collision Assist system detects
a vehicle ahead and starts to apply
Active Braking.
• You turn the steering wheel in an
attempt to steer around the vehicle.
After you turn the steering wheel, the
system applies additional steering torque
to help you steer around the vehicle. After
you pass the vehicle, the system applies
steering torque in the opposite direction to
encourage you to steer back into the lane.
The system deactivates after you fully pass
the vehicle.
Note: The system does not automatically
steer around a vehicle. If you do not turn the
steering wheel, the system does not
activate.
Note: The system does not activate if the
distance to the vehicle ahead is too small
and the system cannot avoid a crash.
Adjusting the Pre-Collision Assist
Settings
You can adjust the following settings by
using the touchscreen. See Settings (page
464
).
• You can change Alert and Distance
Alert sensitivity to one of three possible
settings.
• You can switch Distance Indication and
Alert on or off. •
If required, you can switch Active
Braking on or off.
• If required, you can switch Evasive
Steering Assist on or off.
Note: Active Braking and Evasive Steering
Assist automatically turn on every time you
switch the ignition on.
Note: If you switch Active Braking off,
Evasive Steering Assist turns off.
