506 SERVICING AND MAINTENANCE
(Continued)
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control systems can
result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer's specifications, should
be obtained immediately.To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the vehicle.
• Do not idle the engine with any ignition components disconnected or removed, such as when diagnostic testing,
or for prolonged periods during very rough idle or
malfunctioning operating conditions.Cooling System
• Damage to the catalytic converter can result if yourvehicle is not kept in proper operating condition. In the
event of engine malfunction, particularly involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in possible
damage to the converter and vehicle. CAUTION!
(Continued)
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the radiator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.

Example Tire Placard Location (B-Pillar)
Tire And Loading Information Placard
Tire And Loading Information Placard This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and spare
tires.
Loading
The vehicle maximum load on the tire must not exceed the
load carrying capacity of the tire on your vehicle. You will
not exceed the tire's load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire inflation pres -
sures specified on the Tire and Loading Information placard
in “Vehicle Loading” in the “Starting And Operating”
section of this manual.
NOTE:
Under a maximum loaded vehicle condition, gross axle
weight ratings (GAWRs) for the front and rear axles must not
be exceeded.
For further information on GAWRs, vehicle loading, and
trailer towing, refer to “Vehicle Loading” in the “Starting
And Operating” section of this manual.
2020_DT_1500_OM_US.book Page 522

SERVICING AND MAINTENANCE 523
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX kg or XXX lbs” on
the Tire and Loading Information placard. The combined
weight of occupants, cargo/luggage and trailer tongue
weight (if applicable) should never exceed the weight refer-
enced here.
Steps For Determining Correct Load Limit—

(1) Locate the statement “The combined weight of occupants
and cargo should never exceed XXX kg or XXX lbs.” on your
vehicle's placard.
(2) Determine the combined weight of the driver and passen -
gers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passen -
gers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo
and luggage load capacity. For example, if “XXX” amount
equals 1400 lbs. and there will be five 150 lb passengers in
your vehicle, the amount of available cargo and luggage load
capacity is 650 lbs. (1400-750 (5x150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calcu-
lated in Step 4.
(6) If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available cargo
and luggage load capacity of your vehicle.

Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there will
be five 68 kg passengers in your vehicle, the amount of avail
-
able cargo and luggage load capacity is 295 kg (635-340
(5x68) = 295 kg) as shown in step 4.
NOTE:
• If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. The following
table shows examples on how to calculate total load,
cargo/luggage, and towing capacities of your vehicle with
varying seating configurations and number and size of
occupants. This table is for illustration purposes only and
may not be accurate for the seating and load carry capacity
of your vehicle.
• For the following example, the combined weight of occu -
pants and cargo should never exceed 865 lbs (392 kg).

528 SERVICING AND MAINTENANCE
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the Run
Flat mode. A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the run flat mode it has limited driving capabilities
and needs to be replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after driving with
underinflated tire condition, please replace the TPM sensor
as it is not designed to be reused when driven under run flat
mode 14 psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the vehicle on a
flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat mode.
See the tire pressure monitoring section for more informa-
tion. Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer
-
gency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when you are
stuck, and do not let anyone near a spinning wheel, no
matter what the speed.

532 SERVICING AND MAINTENANCE
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a “moun-
tain/snowflake” symbol on the tire sidewall.
If you need snow tires, select tires equivalent in size
and type to the original equipment tires. Use snow
tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what was
originally equipped with your vehicle and should not be
operated at sustained speeds over 75 mph (120 km/h). For speeds above 75 mph (120 km/h) refer to original equipment
or an authorized tire dealer for recommended safe operating
speeds, loading and cold tire inflation pressures. While studded tires improve performance on ice, skid and
traction capability on wet or dry surfaces may be poorer than
that of non-studded tires. Some states prohibit studded tires;
therefore, local laws should be checked before using these
tire types.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare
tire, please refer to “Tire Service Kit” in “In Case Of Emer
-
gency” for further information.
Refer to the “Towing Requirements - Tires” in “Starting And
Operating” for restrictions when towing with a spare tire
designated for temporary emergency use.
WARNING!
Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury or
death. Driving too fast for conditions also creates the
possibility of loss of vehicle control.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact or limited use temporary spare installed.
Damage to the vehicle may result.

Special Care
• If you drive on salted or dusty roads or if you drive nearthe ocean, hose off the undercarriage at least once a month.
• It is important that the drain holes in the lower edges of the doors, rocker panels, and trunk be kept clear and open.
• If you detect any stone chips or scratches in the paint, touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
• If your vehicle is damaged due to a collision or similar cause that destroys the paint and protective coating, have
your vehicle repaired as soon as possible. The cost of such
repairs is considered the responsibility of the owner.
• If you carry special cargo such as chemicals, fertilizers, de-icer salt, etc., be sure that such materials are well pack -
aged and sealed.
• If a lot of driving is done on gravel roads, consider mud or stone shields behind each wheel.
• Use Mopar Touch Up Paint on scratches as soon as possible. An authorized dealer has touch up paint to
match the color of your vehicle. Spray-On Bedliner – If Equipped
During ownership, the shine and luster of the Spray-On
Bedliner can fade from oxidation, road dirt, heavy-duty
hauling and hard water stains. Weathering and UV exposure
will lead to fading, dulling, and loss of gloss over time.
To help maintain the appearance of your Spray-On Bedliner,
the manufacturer recommends you periodically rinse all
loose dirt from your truck bed and clean your truck at least
twice per year using the Mopar Spray-On Bedliner Condi
-
tioner available at your local authorized dealer.
To Help Maintain The Appearance Of Your Spray-On
Bedliner, Follow The Steps Below:
1. Rinse your truck bed out with water to remove any loose dirt and debris.
2. Mix a mild soap or detergent with water with a soft cloth or brush.
3. Rinse bedliner with water.
4. Once dry, apply a small amount of Mopar Spray-On Bedliner Conditioner to a moist towel or sponge and wipe
over the entire surface of the truck bedliner.
2020_DT_1500_OM_US.book Page 542

SERVICING AND MAINTENANCE 543
Spray-On Bedliners are chemically-resistant to many
different types of chemicals (including gasoline, oil,
hydraulic fluids) for short periods of time. If a spill occurs on
your Spray-On Bedliner, rinse the truck out as soon as
possible to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a Spray-On
Bedliner. One common condition is when loading a heavy
pallet and dragging that pallet across the floor of the bed. If
a nail or sharp point is exposed under the weight of the pallet
a scratch or tear is possible. While not covered by your new
vehicle warranty, a cosmetic fix to cover the metal exposed
by the scratch is required. To repair a tear or gouge, follow
the directions provided in the Mopar Quick Repair Kit.
INTERIORS
Seats And Fabric Parts
Use Mopar Total Clean to clean fabric upholstery and
carpeting.
Stain Repel Fabric Cleaning Procedure — If Equipped
Stain Repel seats may be cleaned in the following manner:
• Remove as much of the stain as possible by blotting with aclean, dry towel.
• Blot any remaining stain with a clean, damp towel.
• For tough stains, apply Mopar Total Clean, or a mild soap solution to a clean, damp cloth and remove stain. Use a
fresh, damp towel to remove soap residue.
WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become
slippery and may result in personal injury.
WARNING!
Do not use volatile solvents for cleaning purposes. Many
are potentially flammable, and if used in closed areas
they may cause respiratory harm.
