ADAPTIVE CRUISE CONTROL
(ACC) — IF EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major road-
ways. However, it is not a safety system and not
designed to prevent collisions.
ACC will allow you to keep cruise control en-
gaged in light to moderate traffic conditions
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-
eration (not to exceed the original set
speed) automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.
WARNING!
•Adaptive Cruise Control (ACC) is a conve-
nience 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 conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
• The ACC system:
• Does not react to pedestrians, on-
coming vehicles, and stationary ob-
jects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
(Continued)
WARNING!(Continued)
•Cannot take street, traffic, and
weather conditions into account, and
may be limited upon adverse sight
distance conditions.
• Does not always fully recognize com-
plex driving conditions, which can
result in wrong or missing distance
warnings.
• Can only apply a maximum of 40% of
the vehicle’s braking capability, and
will not bring the vehicle to a com-
plete stop.

Activating Adaptive Cruise
Control (ACC)
You can only activate ACC if the vehicle speed
is above 18 mph (30 km/h).
When the system is turned on and in the
READY state, the Electronic Vehicle Informa-
tion Center (EVIC) displays “Adaptive Cruise
Ready.”
When the system is OFF, the EVIC displays
“Adaptive Cruise Control Off.”
NOTE:
You cannot enable ACC under the following
conditions:
•When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in
PARK, REVERSE or NEUTRAL.
• When pushing the RES + button without a
previously set speed in memory.
To ActivatePush and release the ON/OFF button. The ACC
menu in the EVIC displays “Adaptive Cruise
Control Ready.”
To turn the system OFF, push and release the
ON/OFF button again. At this time, the system
will turn off and the EVIC will display “Adaptive
Cruise Control Off.”WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave
the system off when you are not using it.
To Set A Desired ACC SpeedWhen the vehicle reaches the speed desired,
push the SET -button and release. The EVIC
will display the set speed.

Remove your foot from the accelerator pedal. If
you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
•The message “DRIVER OVERRIDE” will dis-
play in the EVIC.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be deter-
mined by the position of the accelerator
pedal.To CancelThe system will disable ACC without erasing the
memory if:
•You softly tap the brake pedal.
• You depress the brake pedal.
• You press the CANCEL switch.
• The speed of the vehicle goes below 15 mph
(25 km/h).
• An Anti-Lock Brake System (ABS) event
occurs.
• A Trailer Sway Control (TSC) event occurs.
• The transmission is shifted into NEUTRAL.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.
NOTE:
If ACC is resumed or set with the ESC/TCS
off, ESC will automatically be re-engaged.
To Turn OffThe system will turn off and erase the set speed
in memory if:
• You push the ON/OFF button.
• You turn OFF the ignition.
• You switch to Four-Wheel Drive Low.

To Resume SpeedPress the RES+button and release. Then
remove your foot from the accelerator pedal.
The EVIC will display the last set speed.
NOTE:
You can resume ACC from a minimum of
18 mph (30 km/h).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.
To Vary The Speed SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES +
button. If the button is continually pressed, the
set speed will continue to increase in 5 mph
(10 km/h) increments until the button is re-
leased. The increase in set speed is reflected in
the EVIC display.
Pressing the RES +button once will result in a
1 mph (1 km/h) increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph (1 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button. If the button is continually pressed, the
set speed will continue to decrease in 5 mph
(10 km/h) increments until the button is re-
leased. The decrease in set speed is reflected
in the EVIC display.
Pressing the SET -button once will result in a
1 mph (1 km/h) decrease in set speed. Each
subsequent tap of the button results in a de-
crease of 1 mph (1 km/h). NOTE:
•
When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.
•
The ACC system maintains set speed when
driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and nec-
essary to maintain set speed.
123

The maximum braking applied by ACC is lim-
ited; however, 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
EVIC and a chime will sound while ACC contin-
ues to apply its maximum braking capacity.
When this occurs, you should immediately ap-
ply the brakes as needed to maintain a safe
distance from the vehicle ahead.
The ACC Systems provides Overtake Aid when
passing on the left hand side only. When driving
with ACC engaged and following a Target ve-
hicle, the system will provide an additional
acceleration based on your current speed. The
acceleration is triggered by indicating a left turn
signal.
Adaptive Cruise Control (ACC) MenuThe EVIC displays the current ACC system
settings. The EVIC is located in the upper part
of the instrument cluster between the speedom-
eter and the tachometer. The information it
displays depends on ACC system status.
Adaptive Cruise Control Off
•When ACC is deactivated, the display will
read “Adaptive Cruise Control Off.” Adaptive Cruise Control Ready
•
When ACC is activated but the vehicle speed
setting has not been selected, the display will
read “Adaptive Cruise Control Ready.”
ACC SET
• When ACC is set, the set speed will display.
• The set speed will continue to display in
place of the odometer reading when chang-
ing the EVIC display while ACC is set.

ACC Unavailable Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable, Vehicle System Error”,
there may be a temporary malfunction that
limits ACC functionality. Although the vehicle is
still drivable under normal conditions, ACC will
be temporarily unavailable. If this occurs, try
activating ACC again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable Service Radar Sen-
sor”, it indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.
Precautions While Driving With ACCIn certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.Adding A Trailer Hitch
The weight of a trailer/hitch may affect the
performance of ACC. If there is a noticeable
change in performance following the installation
of a trailer/hitch, or if the ACC performance does
not return to normal after removing the trailer/
hitch see your authorized dealer.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original Set
Speed. This is a part of normal ACC system
functionality.
NOTE:
On tight turns ACC performance may be
limited.
128

Using ACC On Hills
When driving on hills, ACC may not detect a
vehicle in your lane. Depending on the speed,
vehicle load, traffic conditions, and the steep-
ness of the hills, ACC performance may be
limited.Lane Changing
ACC may not detect a vehicle until it is com-
pletely in the lane in which you are traveling. In
the illustration shown, ACC has not yet detected
the vehicle changing lanes and it may not detect
the vehicle until it’s too late for the ACC system
to take action. ACC may not detect a vehicle
until it is completely in the lane. There may not
be sufficient distance to the lane-changing ve-
hicle. Always be attentive and ready to apply the
brakes if necessary.Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.
129

Stationary Objects And Vehicles
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not
react in situations where the vehicle you are
following exits your lane and the vehicle ahead
is stopped in your lane. Always be attentive and
ready to apply the brakes if necessary.General Information

Normal (Fixed Speed) Cruise
Control Mode
In addition to Adaptive Cruise Control mode, a
normal (fixed speed) Cruise Control mode is
available for cruising at fixed speeds. The nor-
mal Cruise Control mode is designed to main-
tain a set cruising speed without requiring the
driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is
above 20 mph (32 km/h).
To change between the different cruise modes,
press the MODE button when the system is in
either the OFF, READY or SET state. Pressing
of the MODE button in any state will result in
changing to the new Mode in the OFF state.
WARNING!
In the normal Cruise Control mode, the sys-
tem will not react to vehicles ahead. In
addition, the proximity warning does not ac-
tivate and no alarm will sound even if you are
too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be
sure to maintain a safe distance between
your vehicle and the vehicle ahead. Always
be aware which mode is selected.
To Set A Desired Speed
When the vehicle reaches the speed desired,
press the SET -button and release. The EVIC
will display the set speed.
NOTE:
You must observe the display when setting
or changing speed, not the speedometer.
