2022 DODGE CHALLENGER ECU

IN CASE OF EMERGENCY253
REAR-WHEEL DRIVE (RWD) MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed. If flatbed equipment is not available, and the
transmission is operable, the vehicle may be flat
towed (with all four wheels on the ground) under
the following conditions:
The transmission must be in NEUTRAL (N).
Instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú
page 249.
The towing distance must not exceed 30 miles
(48 km).
The towing speed must not exceed 30 mph
(48 km/h).
If the transmission is not operable, or the vehicle
must be towed faster than 30 mph (48 km/h) or
farther than 30 miles (48 km), then the only
acceptable method of towing is with a flatbed
truck.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
This feature is a communication network that
takes effect in the event of an impact Úpage 214.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record data that will assist in understanding how a
vehicle’s systems performed under certain crash
or near crash-like situations, such as an air bag
deployment or hitting a road obstacle Úpage 215.
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. Damage to your vehicle may
result from improper towing.
FCA US LLC does not recommend towing this
vehicle using a tow dolly. Vehicle damage may
occur.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine and/or
transmission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.

274SERVICING AND MAINTENANCE
(Continued)
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 255.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
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 container to avoid contamination from
foreign matter or moisture Ú page 316.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 316. 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.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder 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
braking, 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.
