HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to maintain
a set gap between your vehicle and the
vehicle in front of you while following it to a
complete stop. Stop and go can also be set
to follow a vehicle directly in front of you and
adjust the set speed, while you are at a
complete stop.
ADAPTIVE CRUISE CONTROL
PRECAUTIONS
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal

WHAT IS THE LANE KEEPING
SYSTEM
The lane keeping system alerts you by
providing temporary steering assistance or
steering wheel vibration when it detects an
unintended lane departure.
HOW DOES THE LANE KEEPING
SYSTEM WORK
L
ane-K eeping S ystem
The lane keeping system uses a forward
looking camera mounted on the windshield
to monitor vehicle movement within the

When the camera detects a drift out of the
travel lane, the lane keeping system alerts
the driver by vibrating the steering wheel, or
aids the driver by providing a small steering
input to move the vehicle back into the travel
lane.
The driver can select one of three modes: •
Alert (If Equipped)
• Aid
• Alert + Aid
