AutoPark — Rotary Shifter and 8-Speed Transmission
Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK. The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the "P"
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed to replace the need to shift your vehicle into PARK. It is
a back up system and should not be relied upon as the
primary method by which the driver shifts the vehicle
into PARK.

Display and near the shifter. As an added precaution, always
apply the parking brake when exiting the vehicle. If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.
WARNING!
• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the
vehicle. This could result in flash fire causing serious
personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmis -
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.

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
2020_DT_1500_OM_US.book Page 304

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.

2020_DT_1500_OM_US.book Page 305

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.

STARTING AND OPERATING 309
NOTE:
Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic equip-
ment to assess the condition of your transmission.
If the transmission cannot be reset, an authorized dealer
service is required.
Electronic Range Select (ERS) Operation — Eight-Speed
Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the transmis -
sion is in DRIVE. For example, if you set the transmission
gear limit to 4 (fourth gear), the transmission will not shift
above fourth gear (except to prevent engine overspeed), but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically, shifting
between all available gears. Tapping the GEAR- switch (on
the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as the
top available gear. Once in ERS mode, tapping the GEAR- or
GEAR+ switch will change the top available gear. Electronic Range Select (ERS)
To exit ERS mode, simply push and hold the GEAR+ switch
until the gear limit display disappears from the instrument
cluster.

2 — GEAR – Switch
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

33 mph (53 km/h). Once the vehicle speed goes below15 mph (24 km/h) the vehicle height will begin to lower. If
the vehicle speed remains between 15 mph (24 km/h) and
25 mph (40 km/h) for greater than 60 seconds, or the
vehicle speed exceeds 25 mph (40 km/h) the Entry/Exitchange will be cancelled. To return to Normal Height
Mode, push the height selector switch up once while in
Entry/Exit or drive the vehicle over 15 mph (24 km/h).
Entry/Exit mode may not be available due to vehicle
payload, an instrument cluster message will be displayed
when this occurs. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
NOTE:
Entry/Exit mode may be achieved using your key fob for
easier entry/loading. Refer to “Keys” in “Getting To Know
Your Vehicle” for further information. The system requires that the ignition be in the ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors, must be
closed. If a door is opened at any time while the vehicle is
lowering the change will not be completed until the open
door(s) is closed.
This system uses a lifting and lowering pattern which keeps
the headlights from incorrectly shining into oncoming
traffic. When raising the vehicle, the rear of the vehicle will
move up first and then the front. When lowering the vehicle,
the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling to
be disabled. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor
-
mation.
CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.
