ECU DODGE CHALLENGER 2019 Service Manual

WARNING!(Continued)
•A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel nozzle
“clicks” or shuts off, the fuel tank is full. NOTE:
•
When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn on
if the gas cap is not secured properly. Make sure that the
gas cap is tightened each time the vehicle is refueled.Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the instrument
cluster. If this occurs, tighten the fuel filler cap properly
and press the Trip Odometer button to turn off the mes-
sage. If the problem continues, the message will appear the
next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
264 STARTING AND OPERATING

The best way to figure out the total weight of your vehicle
is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect on
the way your vehicle steers and handles and the way the
brakes operate.NOTE:
Refer to the “Vehicle Certification Label” affixed to
the rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
TRAILER TOWING
In this section, you will find safety tips and information on
limits to the type of towing you can reasonably do with
your vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning vehicles
used for trailer towing.
Manual Transmission — If Equipped
Trailer towing with this vehicle is not recommended.
266 STARTING AND OPERATING

WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as possible:
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or chockthe trailer wheels.
(Continued)
WARNING! (Continued)
•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:
1. Max loading as defined on the “Tire and Loading
Information” placard.
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Perform the maintenance listed in the “Scheduled Servic-
ing”. Refer to “Scheduled Servicing” in “Servicing And
Maintenance” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or GCWR ratings.
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.

STARTING AND OPERATING 271

JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is on
a jack.
• The jack is designed to be used as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.
Jack Location/Spare Tire Stowage
The jack and spare tire are both stowed under an access
cover in the trunk. Follow these steps to access the jack and
spare tire.
NOTE: The spare tire must be removed in order to access
the jack.
1. Open the trunk.
2. Lift the access cover using the pull strap.
3. Rotate the fastener securing the spare tire counterclock- wise to remove it.

to the radiator and aids in removing heat from the
engine cooling system.
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 try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
MANUAL PARK RELEASE — 8–SPEED
TRANSMISSION
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park Re-
lease. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating the Manual Park Release. Activating the
Manual Park Release will allow your vehicle to roll
away if it is not secured by the parking brake, or by
proper connection to a tow vehicle. Activating the
Manual Park Release on an unsecured vehicle could
lead to serious injury or death for those in or around
the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.
328 IN CASE OF EMERGENCY

6. While holding the locking tab in the disengaged posi-tion, pull the tether strap to rotate the lever up and
rearward until it locks in place in the vertical position.
The vehicle is now out of PARK and can be moved.
Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the latch (at the base of the lever, on the rear side) rearward (away from the lever) to unlatch the lever. 2. Rotate the Manual Park Release lever forward and
down, to its original position, until the locking tab snaps
into place to secure the lever.
3. Pull up gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Tuck the tether strap into the base of the console. Reinstall the console storage bin.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. For vehicles with automatic transmission, push
and hold the lock button on the gear selector. Then shift
back and forth between DRIVE and REVERSE (with auto-
matic transmission) or FIRST GEAR and REVERSE (with
manual transmission), while gently pressing the accelera-
tor. Use the least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning the
wheels or racing the engine.
Tether Strap
330 IN CASE OF EMERGENCY

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer toManual Park Release in this section
for instructions on shifting the transmission out of PARK
for towing.
CAUTION!
• Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
(Continued)
CAUTION! (Continued)
•The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may occur.
All Wheel Drive (AWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If the transmission and driveline are operable, AWD mod-
els can also be towed with the ignition in the ON/RUN
mode, the transmission in NEUTRAL (not in PARK!), and
the rear wheels OFF the ground with no limitation on
speed or distance. Since the ignition MUST be in the
ON/RUN mode to tow in this manner, AWD vehicles must
be towed with ALL FOUR wheels OFF the ground (e.g. on
a flatbed truck) if the key fob is unavailable.
CAUTION!
• Towing this vehicle using any other method can
cause severe transmission and/or transfer case dam-
age.
• Damage from improper towing is not covered under
the New Vehicle Limited Warranty.

IN CASE OF EMERGENCY 333

Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed con-
tainer to avoid contamination from foreign matter or
moisture.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
