(Continued)(Continued)
NOTE:
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the park brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• When exiting the vehicle, always remove the key fob from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in alocation accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving your vehicle, or it may roll and cause damage or injury.
Also be certain to leave the transmission in PARK.
Failure to do so may allow the vehicle to roll and cause
damage or injury.
WARNING!
• Do not rely on the parking brake to operate effectively if the rear brakes have been immersed in water or mud.
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.

300 STARTING AND OPERATING
If exceptional circumstances should make it necessary to
engage the park brake while the vehicle is in motion, main-
tain upward pressure on the electric park brake switch for as
long as engagement is desired. The BRAKE telltale light will
illuminate, and a continuous chime will sound. The rear stop
lamps will also be illuminated automatically while the
vehicle remains in motion.
To disengage the park brake while the vehicle is in motion,
release the switch. If the vehicle is brought to a complete stop
using the parking brake, when the vehicle reaches approxi -
mately 3 mph, (5 km/h) the parking brake will remain
engaged.
• When exiting the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or move
the vehicle.
• Be sure the parking brake is fully disengaged before driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving your vehicle, or it may roll and cause damage or injury.
Also be certain to leave the transmission in PARK.
Failure to do so may allow the vehicle to roll and cause
damage or injury.
WARNING! (Continued)CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.
WARNING!
Driving the vehicle with the parking brake engaged, or
repeated use of the parking brake to slow the vehicle
may cause serious damage to the brake system. Be sure
the parking brake is fully disengaged before driving;
failure to do so can lead to brake failure and a collision.
2020_DT_1500_OM_US.book Page 300

STARTING AND OPERATING 301
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault light will illuminate. This
may be accompanied by the BRAKE telltale light flashing. In
this event, urgent service of the electric park brake system is
required. Do not rely on the parking brake to hold the vehicle
stationary.
Auto Park Brake
The electric park brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and the
automatic transmission is placed in PARK. Auto Park Brake
is enabled and disabled by customer selection through the
customer programmable features section of the Uconnect
Settings.
Any single auto park brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric Park Brake System
that will engage the park brake automatically if the vehicle is
left unsecured while the ignition is in ON/RUN.For automatic transmissions, the park brake will automati
-
cally engage if all of the following conditions are met:
• The vehicle is at a standstill.
• There is no attempt to depress the brake pedal or acceler -
ator pedal.
• The seat belt is unbuckled.
• The driver door is open.
SafeHold can be temporarily bypassed by pushing the Elec -
tric Park Brake Switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled again once the
vehicle reaches 12 mph (20 km/h) or the ignition is turned to the OFF position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by your autho -
rized dealer. You should only make repairs for which you
have the knowledge and the right equipment. You should
only enter Brake Service Mode during brake service.
When servicing your rear brakes, it may be necessary for you
or your technician to push the rear piston into the rear caliper
bore. With the electric park brake system, this can only be
done after retracting the Electric Park Brake actuator. Fortu-
nately, actuator retraction can be done easily by entering the
5
2020_DT_1500_OM_US.book Page 301

302 STARTING AND OPERATING
(Continued)
Brake Service Mode through the Uconnect Settings in your
vehicle. This menu based system will guide you through the
steps necessary to retract the EPB actuator in order to
perform rear brake service.
Service Mode has requirements that must be met in order to
be activated:
• The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp will
flash continuously while the ignition is ON.

When brake service work is complete, the following steps must
be followed to reset the park brake system to normal operation:

• Ensure the vehicle is at a standstill.
• Press the brake pedal with moderate force.
• Apply the Electric Park Brake Switch.AUTOMATIC TRANSMISSION
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!

• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment and possible injury or damage.

• Your vehicle could move and injure you and others if it is not in PARK. Check by trying to move the transmission gear
selector out of PARK with the brake pedal released. Make
sure the transmission is in PARK before exiting the vehicle.

• The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmission
gear position indicator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely stopped,
and the PARK position is properly indicated, before
exiting the vehicle.

• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is
not firmly pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You could lose
control of the vehicle and hit someone or something.
Only shift into gear when the engine is idling normally
and your foot is firmly pressing the brake pedal.
2020_DT_1500_OM_US.book Page 302

STARTING AND OPERATING 303
NOTE:
You must press and hold the brake pedal while shifting out
of PARK.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the driver
avoid inadvertently leaving the vehicle without placing the
transmission in PARK. This system also locks the transmis-
sion in PARK whenever the ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK when the ignition
is in the ACC mode (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition is
OFF (not in ACC mode) before exiting the vehicle.
• Unintended movement of a vehicle could injure those
in or near the vehicle. As with all vehicles, you should
never exit a vehicle while the engine is running. Before
exiting a vehicle, always come to a complete stop, then
apply the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the ignition is
in the OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When exiting the vehicle, always make sure the igni -
tion is in the OFF mode, remove the key fob from the
vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the transmission gear
selector.
• Do not leave the key fob in or near the vehicle (or in a location accessible to children), and do not leave the
ignition in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
WARNING! (Continued)CAUTION!
• Shift into or out of PARK or REVERSE only after the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL, or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is firmly pressing the brake pedal.

304 STARTING AND OPERATING
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
Eight-Speed Automatic Transmission
The transmission is controlled using a rotary electronic gear
selector located on the instrument panel. The transmission
gear range (PRND) is displayed both above the gear selector
and in the instrument cluster. To select a gear range, simply
rotate the gear selector. You must press the brake pedal to
shift the transmission out of PARK (or NEUTRAL, when the
vehicle is stopped or moving at low speeds). To shift past
multiple gear ranges at once (such as PARK to DRIVE),
simply rotate the gear selector to the appropriate detent.
Select the DRIVE range for normal driving.NOTE:
In the event of a mismatch between the gear selector position
and the actual transmission gear (for example, driver selects
PARK while driving), the position indicator will blink
continuously until the selector is returned to the proper posi
-
tion, or the requested shift can be completed.
The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few hundred miles
(kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE positions. Manual downshifts can be
made using the Electronic Range Select (ERS) shift control.
Pressing the GEAR-/GEAR+ switches (on the steering
wheel) while in the DRIVE position will select the highest
available transmission gear, and will display that gear limit

STARTING AND OPERATING 305
in the instrument cluster as 1, 2, 3, etc. Refer to “Electronic
Range Select (ERS) Operation” in this section for further
information. Some models will display both the selected gear
limit, and the actual current gear, while in ERS mode.Electronic Transmission Gear Selector
Gear Ranges
Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE:
After selecting any gear range, wait a moment to allow the
selected gear to engage before accelerating. This is especially
important when the engine is cold. PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range. Never
attempt to use PARK while the vehicle is in motion. Apply
the parking brake when exiting the vehicle in this range.
When parking on a level surface, you may shift the transmis
-
sion into PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precaution,
turn the front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade.
NOTE:
On four-wheel drive vehicles be sure that the transfer case is
in a drive position.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the key fob.

ignition in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
WARNING! (Continued)
2020_DT_1500_OM_US.book Page 306

STARTING AND OPERATING 307

The following indicators should be used to ensure that you have
properly engaged the transmission into the PARK position:

• Look at the transmission gear position display and verifythat it indicates the PARK position (P), and is not blinking.
• With brake pedal released, verify that the gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete stop.
NEUTRAL (N)

Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake and
shift the transmission into PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
CAUTION!
• DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage
the drivetrain.
• Before moving the transmission gear selector out of PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “In Case Of Emergency” for further
information.

2020_DT_1500_OM_US.book Page 307

308 STARTING AND OPERATING
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), select TOW/HAUL mode or use the
Electronic Range Select (ERS) shift control (refer to "Elec-
tronic Range Select (ERS) Operation" in this section for
further information) to select a lower gear range. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing exces -
sive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmission
temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine may
stall. In some situations, the transmission may not re-engage
if the engine is turned off and restarted. The Malfunction Indicator Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the more serious
conditions, and indicate what actions may be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message indicates the
transmission may not re-engage after engine shutdown,
perform this procedure only in a desired location (prefer
-
ably, at an authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
