DRIVER ADJUSTABLE PEDALS — IF EQUIPPED
The adjustable pedals system is designed to allow a greater
range of driver comfort for steering wheel tilt and seat posi-
tion. This feature allows the brake and accelerator pedals to
move toward or away from the driver to provide improved
position with the steering wheel.
The adjustable pedal switch is located on the instrument
panel, below the headlight switch. Adjustable Pedals Switch
• The pedals can be adjusted with the ignition placed in the OFF position.
• The pedals cannot be adjusted when the vehicle is in
REVERSE or when the Speed Control System or Adaptive
Cruise Control systems are on. The following messages
will appear on vehicles equipped with an instrument
cluster display if the pedals are attempted to be adjusted
when the system is locked out: “Adjustable Pedal Disabled
— Cruise Control Engaged” or “Adjustable Pedal
Disabled — Vehicle In Reverse”.
WARNING!
• Persons who are unable to feel pain to the skin because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, 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 insu -
lates against heat, such as a blanket or steering wheel
covers of any type and material. This may cause the
steering wheel heater to overheat.

338 STARTING AND OPERATING
NOTE:
In order to ensure proper operation, the Speed Control
system has been designed to shut down if multiple Speed
Control functions are operated at the same time. If this
occurs, the Speed Control system can be reactivated by
pushing the Speed Control on/off button and resetting the
desired vehicle set speed.
To Activate
Push the On/Off button to activate the Speed Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the On/Off button a
second time. The cruise indicator light will turn off. The
system should be turned off when not in use.
To Set A Desired Speed
Turn the Speed Control on.
NOTE:
The vehicle should be traveling at a steady speed and on
level ground before pushing the SET (+) or SET (-) button.
When the vehicle has reached the desired speed, push the
SET (+) or SET (-) button and release. Release the accelerator
and the vehicle will operate at the selected speed.
To Vary The Speed Setting
To Increase Speed
When the Speed Control is set, you can increase speed by
pushing the SET (+) button.
WARNING!
Speed 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 control
and have an accident. Do not use Speed Control in heavy
traffic or on roads that are winding, icy, snow-covered or
slippery.
WARNING!
Leaving the 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. You could lose
control and have an accident. Always leave the system
off when you are not using it.

340 STARTING AND OPERATING
To Accelerate For Passing
Press the accelerator as you would normally. When the pedal
is released, the vehicle will return to the set speed.
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 soft tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the vehicle
will deactivate the speed control without erasing the set
speed from memory.
Pushing the on/off button or placing the ignition in the OFF
position, erases the set speed from memory.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE:
The 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 Speed Control.
ADAPTIVE CRUISE CONTROL (ACC) — IF EQUIPPED
Adaptive Cruise Control (ACC) increases the driving conve
-
nience provided by cruise control while traveling on high -
ways and major roadways. However, it is not a safety system
and not designed to prevent collisions. Speed Control func-
tion 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 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 accelerate (not to exceed the original set
speed) automatically to maintain a preset following
distance, while matching the speed of the vehicle ahead.
2020_DT_1500_OM_US.book Page 340

STARTING AND OPERATING 341
(Continued)
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an appro-
priate 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:
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. Always
confirm which mode is selected.WARNING!
• Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driving involve -
ment. It is always the driver’s responsibility to be atten -
tive of road, traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead; and, most impor -
tantly, 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. Failure to follow these warn -
ings 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 conditions into account, and may be limited upon adverse sight
distance conditions.
