ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
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 collisions.
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 an infrared
sensor designed to detect a vehicle directly ahead in your
path.NOTE:
•If the sensor does not detect a vehicle directly ahead of
you, ACC will function in the same way as a standard
cruise control system. For additional information, refer
to “Electronic Speed Control” in this section.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically so
that your vehicle maintains a preset following dis-
tance.

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 conditions,
vehicle speed, distance to the vehicle ahead, and most importantly
brake operation to ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required while driving
to maintain safe control of your vehicle. Failure to follow these
warnings can result in an accident or serious personal injury.
•The ACC system:
\25 Does not react to pedestrians, oncoming vehicles, and stationary
objects (i.e. a stopped vehicle in a traffic jam or a disabled vehicle).
\25 Does not predict the lane curvature or the movement of preceding
vehicles and will not compensate for such changes.
\25 Cannot take street, traffic, and weather conditions into account, and
may be limited upon adverse sight distance conditions.
\25 Does not always fully recognize complex driving conditions, which
can result in wrong or missing distance warnings.
\25 May not detect a vehicle ahead when strong light (for example,
sunrise or sunset) is directly shining on the front of the vehicle.
\25 Can only apply a maximum of 25% of the vehicle’s braking capability,
and will not bring the vehicle to a complete stop.
WARNING!
You should switch off the ACC system:
•When driving in fog; heavy rain; heavy snow;
sleet; heavy traffic; and complex driving situations
(i.e. in highway construction zones).
•When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes; and when towing a trailer.
•When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in an
accident or serious personal injury.

Adaptive Cruise Control (ACC) Operation
The speed control lever (located on the right side of the
steering wheel) operates the ACC system.
Activating Adaptive Cruise Control (ACC)
You can only activate ACC if the vehicle speed is above
25 mph (40 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “ACC READY.”
When the system is OFF, the EVIC displays “ACC OFF.”
NOTE:You cannot enable ACC under the following
conditions:
•When you apply the brakes.
•When the parking brake is set.
•When the automatic transmission is in “P” (Park),
“R” (Reverse), or “N” (Neutral).
•When the Electronic Stability Program (ESP) is
switched off.
•When pushing the RESUME ACCEL switch without a
previously set speed in memory.

To Activate:
Push and release the (“ON/OFF”) button located on the
end of the speed control lever. The ACC menu in the
EVIC displays “ACC 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 “ACC OFF.”
WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-
tally set the system or cause it to go faster than you
want. You could lose control and have an accident.
Always leave the system OFF when you aren’t using
it.

To Set a Desired Speed:
When the vehicle reaches the speed desired, push the
lever down and release (“SET DECEL”). The EVIC will
display the set speed.
Remove your foot from the accelerator pedal. If you do
not, the vehicle may continue to accelerate beyond the set
speed. If this occurs:
•The message “DRIVER OVERRIDE” will display in
the EVIC.
•The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.
156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To Cancel:
The system will disable ACC without erasing the
memory if:
•You softly tap the brake pedal.
•You depress the brake pedal.
•You pull the speed control lever toward you (“CAN-
CEL”).
•The Electronic Stability Program / Traction Control
System (ESP/TCS) activates.
To Turn Off:
The system will turn off and erase the set speed in
memory if:
•You push and release the (“ON/OFF”) button.
•You turn off the ignition.
•You switch off ESP.

To Resume Speed:
Push the lever up and release (“RESUME ACCEL”), and
then remove your foot from the accelerator pedal. The
EVIC will display the last set speed.
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. This
could cause an accident and/or serious injury.
To Vary the Speed Setting:
While ACC is set, you can increase the set speed by lifting
and holding the lever up (“RESUME ACCEL”). If the
lever is continually held, the set speed will continue to
increase in 5 mph (Canada 10 km/h) increments until the
lever is released. The increase in set speed is reflected in
the EVIC display.
Tapping the lever up once will result in a 1 mph (Canada
1 km/h) increase in set speed. Each subsequent tap of the
lever results in an increase of 1 mph (Canada 1 km/h).
While ACC is set, the set speed can be decreased by
pushing and holding the lever down (“SET DECEL”). If
the lever is continually held, the set speed will continue
to decrease in 5 mph (Canada 10 km/h) increments until
the lever is released. The decrease in set speed is reflected
in the EVIC display.

Tapping the lever down once will result ina1mph
(Canada 1 km/h) decrease in set speed. Each subsequent
tap of the lever results in a decrease of 1 mph (Canada
1 km/h).
NOTE:
•When you use the lever to decelerate, if the engine’s
braking power does not slow the vehicle sufficiently to
reach the set speed, the brake system will automati-
cally slow the vehicle.
•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 occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed.
Setting the Following Distance in ACC
The specified following distance for ACC can be set by
varying the distance setting between long, medium, and
short. Using this distance setting and the vehicle speed,
ACC calculates and sets the distance to the vehicle ahead.
This distance setting displays in the EVIC.
1 — Sensor Bars. Default Distance Setting is Three Bars = Long.UNDERSTANDING THE FEATURES OF YOUR VEHICLE 159
