2018 DODGE CHALLENGER engine

Preparations For Jump Start
The battery is stored under an access cover in the trunk.
Remote battery posts are located on the right side of the
engine compartment for jump starting.
WARNING!
•Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Apply the parking brake, shift into PARK (automatic transmission) or FIRST GEAR (manual transmission)
and cycle the ignition to OFF.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
Jump Starting Locations
(+) — Remote Positive Post
(-) — Remote Negative Post 306 IN CASE OF EMERGENCY

3. If using another vehicle to jump start the battery, parkthe vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury
could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle. Connecting The Jumper Cables
1. Connect the positive
(+)end of the jumper cable to the
remote positive (+)post of the vehicle with the dis-
charged battery.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative (-)end of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to the remote negative (-)post of the vehicle with
the discharged battery.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.

6. Once the engine is started, remove the jumper cables inthe reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the remote negative (-)post of the vehicle with the
discharged battery.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the remote positive (+)post of the vehicle
with the discharged battery.
If frequent jump starting is required to start your vehicle
you should have the battery and charging system in-
spected at an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
(Continued)
CAUTION! (Continued)
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
•On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
308 IN CASE OF EMERGENCY

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.

IN CASE OF EMERGENCY 309

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.
NOTE: For vehicles with automatic transmission: Shifts
between DRIVE and REVERSE can only be achieved at
wheel speeds of 5 mph (8 km/h) or less. Whenever the
transmission remains in NEUTRAL for more than two
seconds, you must press the brake pedal to engage DRIVE
or REVERSE.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at

CAUTION!(Continued)
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.
NOTE: Push the “ESC Off” switch (if necessary), to place
the Electronic Stability Control (ESC) system in “Partial
Off” mode, before rocking the vehicle. Refer to “Electronic
Brake Control System” in “Safety” for further information.
Once the vehicle has been freed, push the ESC Offswitch
again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between
DRIVE / FIRST GEAR and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
312 IN CASE OF EMERGENCY

Rear-Wheel Drive (RWD) Models
The manufacturer 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. Refer to
Manual Park Release in this section for instructions on
shifting the automatic transmission to NEUTRAL when
the engine is off.
• 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.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Enhanced Accident Re-
sponse System (EARS) function.
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 per-
formed under certain crash or near crash-like situations,
such as an air bag deployment or hitting a road obstacle.
