2021 DODGE CHALLENGER key battery

STARTING AND OPERATING81
ALWAYS DO A VISUAL CHECK
that your vehicle is in
PARK by looking for the "P" in the instrument
cluster display and on the gear selector. As an
added precaution, always apply the parking brake
when exiting the vehicle.
COLD WEATHER OPERATION
(BELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” or “Cold Weather Operation”
procedure, it may be flooded. Push the accelerator
pedal all the way to the floor and hold it there.
Crank the engine for no more than 15 seconds. This should clear any excess fuel in case the
engine is flooded. Leave the ignition key in the RUN
position, release the accelerator pedal and repeat
the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater must be plugged in at
least one hour to have an adequate warming effect
on the engine.
The engine block heater cord is routed under the
hood on the driver side of the vehicle. It has a
removable cap that is located near the air box.
WARNING!

If vehicle speed is above 1.2 mph (1.9 km/h),
the transmission will default to NEUTRAL until
the vehicle speed drops below 1.2 mph
(1.9 km/h). A vehicle left in the NEUTRAL
position can roll. As an added precaution,
always apply the parking brake when exiting the
vehicle.

WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto
-
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 238.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 25
seconds at a time. Wait 60 seconds before
trying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

SAFETY207
NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the
engine.
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like
situations, such as an air bag deployment or hitting
a road obstacle, data that will assist in
understanding how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such data
as:
How various systems in your vehicle were oper -
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo -
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.

It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.

Do not attempt to modify any part of your air
bag system. The air bag may inflate accidentally
or may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat,
including your trim cover and cushion, needs to
be serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may
be used. If it is necessary to modify the air bag
system for persons with disabilities, contact an
authorized dealer.

IN CASE OF EMERGENCY245
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 mandatory. Attach a tow bar
or other towing device to main structural members
of the vehicle, not to fascia/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, find Instructions on shifting the
transmission out of PARK Ú page 241.
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 241.
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 206.
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 207.
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.
