3. Pull the cord to the front of the vehicle and plug it into agrounded, three-wire extension cord.
4. After the vehicle is running, reattach the cord to the hook-and-loop strap and properly stow away behind the
driver’s side headlamp.
NOTE:
• The engine block heater cord is a factory installed option. If your vehicle is not equipped, heater cords are available
from your authorized Mopar dealer.

• The engine block heater will require 110 Volts AC and 6.5 Amps to activate the heater element.

• The engine block heater must be plugged in at least one hour to have an adequate warming effect on the engine.ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri -
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

STARTING AND OPERATING 161
NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave an automatic trans-
mission in PARK, or manual transmission in REVERSE or
first gear.
The parking brake lever is located in the center console. To
apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, press the center button, then lower the lever
completely. Parking Brake
When the parking brake is applied with the ignition switch
in the ON position, the “Brake Warning Light” in the instru-
ment cluster will illuminate.

AUTOMATIC TRANSMISSION
NOTE:
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
• 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.
• 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, turn the engine OFF, and remove the ignition
key. Once the key is removed, the transmission is
locked in PARK, securing the vehicle against unwanted
movement.
• When leaving the vehicle, always remove the ignition key from the vehicle and lock the vehicle.• Never leave children alone in a vehicle, or with accessto 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 ignition key in or near the vehicle (or in a location accessible to children). A child could
operate power windows, other controls, or move the
vehicle.
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.

164 STARTING AND OPERATING
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the full STOP (OFF/LOCK) (key
removal) position. The key can only be removed from the
ignition when the ignition is in the STOP (OFF/LOCK) posi-
tion, and once removed, the transmission is locked in PARK.
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 ignition must be in the MAR/
RUN mode (engine running or not) 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.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear selector
and move the lever rearward or forward. You must also press the brake pedal to shift the transmission out of PARK
(or NEUTRAL, when the vehicle is stopped or moving at low
speeds). 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
REVERSE while driving forward), the position indicator will
blink continuously until the selector is returned to the proper
position, 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
or kilometers.
The nine-speed transmission has been developed to meet the
needs of current and future FWD/AWD vehicles. Software
and calibration is refined to optimize the customer’s driving
experience and fuel economy. By design, some vehicle and
driveline combinations utilize 9th gear only in very specific
driving situations and conditions.

STARTING AND OPERATING 165
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 provides PARK, REVERSE,
NEUTRAL, DRIVE, and Electronic Range Select (ERS) shift
positions. Manual downshifts can be made using the ERS
shift control. Moving the gear selector into the ERS (-/+)
position (beside the DRIVE position) activates ERS mode,
displays the current gear in the instrument cluster, and
prevents automatic upshifts beyond this gear. In ERS mode,
toggling the gear selector forward (-) or rearward (+) will
change the highest available gear. Refer to "Electronic Range
Select (ERS) Operation" in this section for further informa-
tion.
NOTE:
If the gear selector cannot be moved to the PARK, REVERSE,
or NEUTRAL position (when pushed forward) it is probably
in the ERS (+/-) position (beside the DRIVE position). In ERS
mode, the transmission gear limit (1, 2, 3, etc.) is displayed in
the instrument cluster. Move the gear selector to the right
(into the DRIVE [D] position) for access to PARK, REVERSE,
and NEUTRAL. 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.

166 STARTING AND OPERATING
(Continued)
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, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of 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.
When exiting the vehicle, always:
• Apply the parking brake,
• Shift the transmission into PARK,
• Turn the engine OFF, and
• Remove the ignition key.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 gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK 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.

STARTING AND OPERATING 167
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, push the lock button on the gear selector and firmly move the selector all the way forward
until it stops and is fully seated.
• Look at the transmission gear position display and verify that it indicates the PARK position.
• 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.
• 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, turn the engine OFF, and remove the ignition
key. Once the key is removed, the transmission is
locked in PARK, securing the vehicle against unwanted
movement.
• When exiting the vehicle, always remove the ignition key 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 ignition key in or near the vehicle (or in a location accessible to children). A child could
operate power windows, other controls, or move the
vehicle.
WARNING! (Continued)CAUTION!
• Before moving the transmission gear selector out of PARK, you must turn the ignition to the ON/RUN
mode, and also press the brake pedal. Otherwise,
damage to the gear selector could result.
• DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage
the drivetrain.

168 STARTING AND OPERATING
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.
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), use the Electronic Range Select (ERS)
shift control refer to “Electronic Range Select (ERS) Opera
-
tion” 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 excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the transmis -
sion shift schedule, reduce engine torque, and/or expand the
range of torque converter clutch engagement. This is done to
prevent transmission damage due to overheating.
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_RAM_PROMASTER_CITY_OM_USA=GUID-7B6A7FCA-79B0-423F-95C5-ED2A949C3D13=1=en=.book Page 168

STARTING AND OPERATING 169
If the transmission becomes extremely hot, the “Transmis-
sion Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera -
ture as well as vehicle speed. This feature improves warm up
time of the engine and transmission to achieve maximum
efficiency. Engagement of the torque converter clutch, and
shifts into 8th or 9th gear, are inhibited until the transmission
fluid is warm refer to the “Note” under “Torque Converter
Clutch” in this section. 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 a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the trans -
mission. In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 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.
NOTE:
Even if the transmission can be reset, we recommend that
you visit your authorized dealer at your earliest possible
convenience. Your authorized dealer has diagnostic equip -
ment to assess the condition of your transmission. If the
transmission cannot be reset, authorized dealer service is
required.

170 STARTING AND OPERATING
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically at
calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some acceler-
ations, the clutch automatically disengages.
NOTE:
The torque converter clutch will not engage until the trans -
mission fluid is warm [usually after 1 to 3 miles (2 to 5 km)
of driving]. Because the engine speed is higher when the
torque converter clutch is not engaged, it may seem as if the
transmission is not shifting properly when cold. This is
normal. The torque converter clutch will function normally
once the transmission is sufficiently warm.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if you
set the transmission gear limit to 5 (fifth gear), the transmis -
sion will not shift above fifth gear, but will shift through the
lower gears normally. You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE posi
-
tion, the transmission will operate automatically, shifting
between all available gears.
Moving the gear selector to the ERS position (beside DRIVE)
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, moving the gear selector forward (-) or
rearward (+) will change the top available gear, which will
be displayed in the instrument cluster.
To exit ERS mode, simply return the gear selector to the
DRIVE position.
NOTE:
To select the proper gear position for maximum deceleration
(engine braking), move the gear selector into the ERS posi -
tion, then simply press and hold it forward (-). The transmis -
sion will shift to the range from which the vehicle can best be
slowed down.
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.
