maintenance DODGE CHARGER 2020 Owner's Manual

STARTING AND OPERATING207
(Continued)
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to “Tires” in “Servicing And
Maintenance” for proper tire inflation proce -
dures.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires” in “Servicing And Maintenance” for
the proper inspection procedure.
When replacing tires, refer to “Tires” in
“Servicing And Maintenance” for the proper
tire replacement procedures. Replacing tires
with a higher load carrying capacity will not
increase the vehicle's GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inad -
equate braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
GCWR must not be exceeded.
Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts could
be damaged.
WARNING! (Continued)
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
CAUTION! (Continued)

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
3.6L AND 5.7L ENGINES
These vehicles are equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the
“Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can
cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
The “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change
is necessary.An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off-road environment,
or is operated predominantly at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before your
next scheduled service.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
(if equipped) and fill as needed.
Check function of all interior and exterior
lights.
Maintenance Plan — 3.6L And 5.7L
Required Maintenance Intervals:
Refer to the maintenance schedules on the
following page for the required maintenance
intervals. More frequent maintenance may be
needed in severe conditions, such as dusty
areas and very short trip driving. In some
extreme conditions, additional maintenance
not specified in the maintenance schedule may
be required.

20_LD_OM_EN_USC_t.book Page 250

SERVICING AND MAINTENANCE251
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter
Rotate the tires
Rotate at the first sign of irregular wear, even if it occurs before your next scheduled service
Inspect battery and clean and tighten terminals as required
Inspect brake pads, shoes, rotors, drums, hoses and park brake
Inspect the CV/Universal joints
Inspect engine cooling system protection and hoses
Inspect exhaust system
Inspect engine air cleaner if using in dusty or off-road conditions, replace engine air cleaner if necessary
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty
conditions

The scheduled maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle
warranty and ensure the best vehicle
performance and reliability. More frequent
maintenance may be needed for vehicles in
severe operating conditions, such as dusty
areas and very short trip driving. Inspection and
service should also be done anytime a
malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for
scheduled maintenance.
An “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change
is necessary. Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been six
months since your last oil change, even if the
oil change indicator message is NOT illumi-
nated.
Change your engine oil more often if you drive
your vehicle off-road/track usage for an
extended period of time.
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
6 months, whichever comes first.
WARNING!
You can be badly injured working on or
around a motor vehicle. Do only 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.

your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
