ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving con-
venience provided by cruise control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions.Speed
Control function performs differently. Please refer to the
proper section within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor
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 acceleration (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 maintaining an ap-
propriate distance between vehicles.
• Normal (fixed speed) cruise control mode is for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode” in
this section.
NOTE: The 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. Al-
ways confirm which mode is selected.
WARNING!
• Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibility
to be attentive of road, traffic, and weather condi-
tions, vehicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to ensure safe

Vehicle Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance setting, re-
gardless of the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of the
sensor.
• The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity. NOTE:
The “Brake!” Screen in the instrument cluster
display is a warning for the driver to take action and does
not necessarily mean that the Forward Collision Warning
system is applying the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver utilizes
the left turn signal and will only be active when passing on
the left hand side.
Brake Alert

•The braking temperature exceeds normal range (over-
heated).
• The gear selector is removed from the DRIVE position.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Turn Off
The system will turn off and erase the set speed in memory
if:
•The Normal (Fixed Speed) Cruise Control on/off button
is pushed.
• The ignition is turned OFF.
• The Adaptive Cruise Control (ACC) on/off button is
pushed.
FORWARD COLLISION WARNING (FCW) — IF
EQUIPPED
Forward Collision Warning (FCW) Operation
The Forward Collision Warning (FCW) system provides
the driver with audible warnings, visual warnings (within the instrument cluster display), to warn the driver when it
detects a potential frontal collision. The warnings are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE:
FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings.FCW Message

reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” located
in the instrument cluster will start to flash as soon as the
ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the TCS is
active. If the “ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing road
conditions.
WARNING!
• Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
