NOTE:
When you override and push the SET
(+)
or SET
(-)
but-
ton, the new set speed will be the current speed of the
vehicle.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is
released, the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise 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 Cruise
Control.
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose con-
trol and have an accident. Do not use Cruise Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
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 Deactivate
A tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the
vehicle will deactivate the Cruise Control system with-
out erasing the set speed from memory.
The following conditions will also deactivate the Cruise
Control system without erasing the set speed from
memory:
•
Vehicle parking brake is applied
•
Stability event occurs
•
Gear selector is moved out of DRIVE
•
Engine overspeed occurs
Pushing the on/off button or placing the ignition in the
OFF position, erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
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.
The Cruise Control function performs differently
page 125.
ACC will allow you to keep Cruise Control engaged in
light to moderate traffic conditions without the constant
need to reset your speed. ACC utilizes a radar sensor
and a forward facing camera designed to detect a
vehicle directly ahead of you to maintain a set speed.
NOTE:
•
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.
•
Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adap-
tive Cruise Control and Forward Collision Warning
system.
•
Fixed Speed Cruise Control (ACC not enabled) will
not detect vehicles directly ahead of you. Always be
aware of the feature selected
page 346.
WARNING!
•
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver
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 operation of the vehicle under all road condi-
tions. Your complete attention is always required
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
vehicles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
○
Cannot take street, traffic, and weather condi-
tions into account, and may be limited upon
adverse sight distance conditions.
