WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion, or other physical conditions must exercise
care when using the steering wheel heater. It may
cause burns even at low temperatures, especially if
used for long periods.
•Do not place anything on the steering wheel that
insulates against heat, such as a blanket or steering
wheel covers of any type and material. This may
cause the steering wheel heater to overheat.
ELECTRONIC SPEED CONTROL
When engaged, the Electronic Speed Control takes over
accelerator operations at speeds greater than 20 mph
(32 km/h).The Electronic Speed Control buttons are located on the
right side of the steering wheel.

NOTE:In order to ensure proper operation, the Electronic
Speed Control System has been designed to shut down if
multiple Speed Control functions are operated at the same
time. If this occurs, the Electronic Speed Control System can
be reactivated by pushing the Electronic Speed Control
ON/OFF button and resetting the desired vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in the
instrument cluster will illuminate. To turn the system off,
push the ON/OFF button a second time. The Cruise Indica-
tor Light will turn off. The system should be turned off when
not in use.
WARNING!
Leaving the Electronic Speed Control system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
(Continued)
WARNING!(Continued)
You could lose control and have an accident. Always
leave the system OFF when you are not using it.
To Set A Desired Speed
Turn the Electronic Speed Control ON. When the vehicle
has reached the desired speed, press the SET (-) button and
release. Release the accelerator and the vehicle will operate
at the selected speed.
NOTE:The vehicle should be traveling at a steady speed
and on level ground before pressing the SET button.
To Deactivate
A soft tap on the brake pedal, pushing the CANCEL
button, or normal brake pressure while slowing the vehicle
will deactivate Electronic Speed Control without erasing
the set speed memory. Pressing the ON/OFF button or
turning the ignition switch OFF erases the set speed
memory.

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 Vary The Speed Setting
When the Electronic Speed Control is set, you can in-
crease speed by pushing the RES (+) button. If the button
is continually pressed, the set speed will continue to
increase until the button is released, then the new set
speed will be established.
Pressing the RES (+) button once will result ina1mph
(1.6 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1.6 km/h).
To decrease speed while the Electronic Speed Control is
set, push the SET (-) button. If the button is continually
held in the SET (-) position, the set speed will continue todecrease until the button is released. Release the button
when the desired speed is reached, and the new set speed
will be established.
Pressing the SET (-) button once will result ina1mph
(1.6 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1.6 km/h).To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 217

NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
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.
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.
218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity 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 re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
•The ACC system:
– Does not react to pedestrians, oncoming ve-
hicles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
(Continued)
WARNING!(Continued)
– Cannot take street, traffic, and weather condi-
tions into account, and may be limited upon
adverse sight distance conditions.
– Does not predict the lane curvature or the move-
ment of preceding vehicles and will not compen-
sate for such changes.
– Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
– Can only apply a maximum of 25% of the vehi-
cle’s braking capability, and will not bring the
vehicle to a complete stop.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 219

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.
•When towing a trailer up or down steep slopes.
•When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in a
collision and death or serious personal injury.The Cruise Control system has two control modes:
•Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
•Normal (fixed speed) cruise control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode”
in this section.
NOTE:The system 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.
Always confirm which mode is selected.
Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operates the ACC system.
220 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:Any chassis/suspension modifications to the ve-
hicle will effect the performance of the Adaptive Cruise
Control.
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 Information Center (EVIC) dis-
plays “Adaptive Cruise Ready.”
When the system is OFF, the EVIC displays “Adaptive
Cruise Control Off.”

VERSE or NEUTRAL.
•When pushing the RES+button without a previously
set speed in memory.
To Activate
Push 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
