Lights-On Reminder
If the headlights, parking lights, or cargo lights are left on
after the ignition is placed in the OFF position, a chime will
sound when the driver’s door is opened.
Front Fog Lights — If Equipped
To activate the front fog lights, turn on the parking lights or
low beam headlights and push in the center of the headlight
switch control knob. Pushing the headlight switch control
knob a second time will turn the front fog lights off.Front Fog Light Switch If the fog lights are off, one of the fog lights will illuminate
depending on the direction in which the vehicle is turning.
This will provide increased visibility while turning,
depending on the angle of the steering wheel.
Turn Signals
Move the multifunction lever up or down and the arrows on
each side of the instrument cluster display will flash to show
proper operation of the front and rear turn signal lights.
NOTE:
If either light remains on and does not flash, or there is a very
fast flash rate, check for a defective outside light bulb. If an
indicator fails to light when the lever is moved, it would
suggest that the indicator bulb is defective.
Lane Change Assist — If Equipped
Tap the multifunction lever up or down once, without
moving beyond the detent, and the turn signal (right or left)
will flash three times then automatically turn off.

110 GETTING TO KNOW YOUR VEHICLE
NOTE:
HomeLink® is disabled when the Vehicle Security Alarm is
active.
NOTE:
Only use this transceiver with a garage door opener that has
a “stop and reverse” feature as required by federal safety
standards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door openerwithout these safety features. Call toll-free 1-800-355-3515 or,
on the Internet at HomeLink.com for safety information or
assistance.
Before You Begin Programming HomeLink®
Be sure that your vehicle is parked outside of the garage
before you begin programming.
For more efficient programming and accurate transmission
of the radio-frequency signal it is recommended that a new
battery be placed in the hand-held transmitter of the device
that is being programmed to the HomeLink® system.
To erase the channels, place the ignition in the ON/RUN
position, and push and hold the two outside HomeLink®
buttons (I and III) for up to 20 seconds or until the orange
indicator flashes.
NOTE:
• Erasing all channels should only be performed when programming HomeLink® for the first time. Do not erase
channels when programming additional buttons.
• If you have any problems, or require assistance, please call toll-free 1-800-355-3515 or, on the Internet at Home-
Link.com for information or assistance.
WARNING!
• Your motorized door or gate will open and close while you are programming the universal transceiver. Do not
program the transceiver if people, pets or other objects
are in the path of the door or gate. Only use this trans -
ceiver with a garage door opener that has a “stop and
reverse” feature as required by Federal safety stan -
dards. This includes most garage door opener models
manufactured after 1982. Do not use a garage door
opener without these safety features.
• Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run your vehicle in the garage
while programming the transceiver. Exhaust gas can
cause serious injury or death.

182 GETTING TO KNOW YOUR INSTRUMENT PANEL
NOTE:
This light may turn on if the accelerator and brake pedals are
pressed at the same time.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have the
system checked by an authorized dealer. — Electric Power Steering Fault Warning Light

This warning light will turn on when there's a fault with the
Electric Power Steering (EPS) system. Refer to “Power Steering”
in “Starting And Operating” for further information.
— Tailgate Open Warning Light
This warning light will illuminate when the tailgate is open.
NOTE:
If the vehicle is moving, there will also be a single chime.
— Trailer Brake Disconnected Warning Light
This warning light will illuminate when the Trailer Brake has
been disconnected.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high transmis -
sion fluid temperature. This may occur with strenuous usage
such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the trans -
mission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive normally.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a fire.

SAFETY 207
Disabling HDC
HDC will be deactivated and disabled if any of the following
conditions occur:
• The driver pushes the HDC switch.
• The driveline is shifted out of the 4L Range.
• The park brake is applied.
• The driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) forgreater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (HDC exits immediately).
• HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate and remain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several seconds, then extinguish when the driver pushes the HDC
switch but enable conditions are not met. • The cluster icon and switch lamp will flash for several
seconds, then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is designed to mitigate
roll back from a complete stop while on an incline. If the
driver releases the brake while stopped on an incline, HSA
will continue to hold the brake pressure for a short period. If
the driver does not apply the throttle before this time expires,
the system will release brake pressure and the vehicle will
roll down the hill as normal.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.4
2020_DT_1500_OM_US.book Page 207

208 SAFETY
The following conditions must be met in order for HSA to
activate:
• The feature must be enabled.
• The vehicle must be stopped.
• The park brake must be off.
• The driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction (i.e.,vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE (R) gear).
• HSA will work in REVERSE (R) gear and all forward gears. The system will not activate if the transmission is in PARK
(P) or NEUTRAL (N). For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to other
vehicles, people, and objects, 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 a collision or serious personal injury.
