• ONLY install floor mats designed to fit your vehicle.NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver’s side floor mat on the driver’s side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger’s side floor mat on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or slide into the driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
WARNING! (Continued)
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-second
intervals. Waiting a few seconds between such intervals will
protect the starter from overheating.
WARNING!
• When leaving the vehicle, always make sure the keyless ignition node 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 gear selector.
• Do not leave the key fob in or near the vehicle, or in alocation 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.
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause
serious injury or death.

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.

STARTING AND OPERATING 297
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”. 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
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake System
(EPB) that offers simple operation, and some additional
features that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the vehicle,
make sure that the park brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature in
the customer programmable features section of the Ucon -
nect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.5

298 STARTING AND OPERATING
The park brake switch is located on the instrument panel to
the left of the steering wheel (below the headlamp switch).Electric Park Brake Switch
To apply the park brake manually, pull up on the switch
momentarily. You may hear a slight whirring sound from
the back of the vehicle while the park brake engages. Once
the park brake is fully engaged, the BRAKE telltale light in
the instrument cluster and an indicator on the switch will
illuminate. If your foot is on the brake pedal while you apply
the park brake, you may notice a small amount of brake
pedal movement. The park brake can be applied even when
the ignition switch is OFF but the BRAKE telltale light will
not illuminate, however, it can only be released when the
ignition is in the ON/RUN mode. NOTE:
The EPB fault light will illuminate if the EPB switch is held
for longer than 20 seconds in either the released or applied
position. The light will extinguish upon releasing the switch.
If the Auto Park Brake feature is enabled, the parking brake
will automatically engage whenever the transmission is
placed into PARK. If your foot is on the brake pedal, you may
notice a small amount of brake pedal movement while the
park brake is engaging.
The park brake will release automatically when the ignition
is ON, the transmission is in DRIVE or REVERSE, the driver
seat belt is buckled, and an attempt is made to drive away.
To release the park brake manually, the ignition switch must
be in the ON/RUN mode. Put your foot on the brake pedal,
then push the park brake switch down momentarily. You
may hear a slight whirring sound from the back of the
vehicle while the parking brake disengages. You may also
notice a small amount of movement in the brake pedal. Once
the park brake is fully disengaged, The BRAKE telltale light
in the instrument cluster and the LED indicator on the switch
will extinguish.
2020_DT_1500_OM_US.book Page 298

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

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.
2020_DT_1500_OM_US.book Page 308

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.

310 STARTING AND OPERATING
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting occurs,
push the TOW/HAUL switch to activate TOW/HAUL
mode. This will improve performance and reduce the poten-
tial for transmission overheating or failure due to excessive
shifting.
TOW/HAUL Switch The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default at
engine start-up. If TOW/HAUL mode is desired, the switch
must be pushed each time the engine is started.
FOUR-WHEEL DRIVE OPERATION — IF EQUIPPED
Four-wheel drive trucks are equipped with either a manu-
ally shifted transfer case or an electronically shifted transfer
case. Refer to the operating instructions for your transfer
case, located in this section for further information.
WARNING!
Do not use the “TOW/HAUL” feature when driving in
icy or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.
