2021 CHRYSLER 300 air condition

STARTING AND OPERATING 83
NOTE:
For Keyless Enter ‘n Go™ equipped vehicles, the
e n
gine will turn off and the ignition switch will
change to ACC Mode.
If the vehicle is not in PARK and the driver exits the
v e

hicle with the engine running, the vehicle may
AutoPark.
AutoPark will engage when all of these conditions
a r

e met:
Vehicle is equipped with a rotary selector and an
eight speed transmission
Vehicle is not in PARK
Vehicle speed is 1.2 mph (1.9 km/h) or less
Driver’s seat belt is unbuckled
Driver’s door is ajar
Brake pedal is not pressed
The message “ Au
toPark Engaged Shift to P then
Shift to Gear ” will display in the instrument cluster.
NOTE:
In some cases the ParkSense graphic will be
d i
splayed in the instrument cluster. In these cases,
the gear selector must be returned to “P” to select
desired gear.
If the driver shifts into PARK while moving, the
ve
hicle may AutoPark.
AutoPark will engage ON
LY when vehicle speed is
1.2 mph (1.9 km/h) or less. The message “
Ve
hicle Speed is Too High to Shift to
P” will be displayed in the instrument cluster if
vehicle speed is above 1.2 mph (1.9 km/h).
ALWAYS DO A VISUAL CHECK
that your vehicle is in
PARK by looking for the “P” in the instrument
cluster display and near the gear selector. As an
added precaution, always apply the parking brake
when exiting the vehicle.
COLD WEATHER OPERATION
(B
ELOW –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.
WARNING!

If vehicle speed is above 1.2
mph (1.9 km/h), the
tr
ansmission will default to NEUTRAL until the
vehicle speed drops below 1.2 mph (1.9 km/h). A
ve

hicle 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
w a

y. 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

84 STARTING AND OPERATING
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
le

ast one hour to have an adequate warming effect
on the engine.
The engine block heater cord is routed under the
h ood

on the driver side of the vehicle. It has a
removable cap that is located near the air box.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
drivetrain (engine, transmission, and rear axle) in
your new vehicle.
Drive moderately during the first 300 miles
( 5

00 km). After the initial 60 miles (100 km),
s p
eeds up to 50 or 55 mph (80 or 90 km/h) are
d e
sirable.
While cruising, brief full-throttle acceleration within
th
e limits of local traffic laws contributes to a good
break-in. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
l u

bricant installed at the factory are high-quality
and energy-conserving. Oil, fluid, and lubricant
changes should be consistent with anticipated
climate and conditions under which vehicle
operations will occur. For the recommended
viscosity and quality grades
Ú page 249.
NOTE:
A new engine may consume some oil during its first
f e
w thousand miles (kilometers) of operation. This should be considered a normal part of the break-in
and not interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi
-
cator often during the break in period. Add oil as
r e

quired.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK position.
The foot operated parking brake is located below
th

e lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake,
press the parking brake pedal a second time and
let your foot up as you feel the brake disengage.

Parking Brake

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
t r

ying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being
on in your vehicle can cause erratic or noisy
performance from your radio. This condition may
be lessened or eliminated by repositioning the
mobile phone within the vehicle. This condition is
not harmful to the radio. If your radio performance
does not satisfactorily improve from repositioning
the mobile phone, it is recommended that the
volume be turned down or off during mobile phone
operation when not using the Uconnect system.

138 SAFETY
Brake Warning Light does not come on when the
ignition is placed in the ON/RUN mode, have the
light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Roll Mitigation
(ERM), Electronic Stability Control (ESC), Hill Start
Assist (HSA), and Traction Control System (TCS).
These systems work together to enhance both
vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Rain Brake
S u

pport (RBS) and Ready Alert Braking (RAB).
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or
com

es on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering the Anti-Lock Brake System (ABS) before
the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, striking
objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off”
m od
e (if equipped). See Ú page 139 in this
section for a complete explanation of the available
E S
C modes.
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.

SAFETY 153
(Continued)
Initial Indication
If the driver is unbuckled when the ignition switch
i s

first in the START or ON/RUN position, a chime
will signal for a few seconds. If the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled when the ignition switch is first in the
START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard
front seat belts are buckled. The outboard front
passenger seat BeltAlert is not active when an
outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when
t h

e vehicle is moving above a specified vehicle
speed range and the driver or outboard front seat
passenger is unbuckled (if equipped with outboard
front passenger seat BeltAlert) (the outboard front
passenger seat BeltAlert is not active when the
outboard front passenger seat is unoccupied). The
BeltAlert warning sequence starts by blinking the
Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning
sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may
repeat based on vehicle speed until the driver and
occupied outboard front seat passenger seat belts
are buckled. The driver should instruct all
occupants to buckle their seat belts. Change of Status
If the driver or outboard front seat passenger (if
e
q

uipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert is not
a c

tive when the outboard front passenger seat is
unoccupied. BeltAlert may be triggered when an
animal or other items are placed on the outboard
front passenger seat or when the seat is folded flat
(if equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat
belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by an
a u

thorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated and the driver or
ou t
board front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled the Seat Belt Reminder Light will turn
on and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped
with lap/shoulder belts.
The seat belt webbing retractor will lock only during
ve
ry sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the inte -
rior of your vehicle or other passengers, or you
c a

n be thrown out of the vehicle. Always be
sure you and others in your vehicle are
buckled up properly.

154 SAFETY
(Continued)
It is dangerous to ride in a cargo area, inside
or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri-
ously injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and
seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear their
seat belts whether or not an air bag is also
provided at their seating position to minimize
the risk of severe injury or death in the event
of a crash.
Wearing your seat belt incorrectly could make
your injuries in a collision much worse. You
might suffer internal injuries, or you could
even slide out of the seat belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
Two people should never be belted into a
single seat belt. People belted together can
crash into one another in a collision, hurting
one another badly. Never use a lap/shoulder
belt or a lap belt for more than one person, no
matter what their size.
WARNING!WARNING!
A lap belt worn too high can increase the risk
of injury in a collision. The seat belt forces
won’t be at the strong hip and pelvic bones,
but across your abdomen. Always wear the lap
part of your seat belt as low as possible and
keep it snug.
A twisted seat belt may not protect you prop -
erly. In a collision, it could even cut into you.
B e
sure the seat belt is flat against your body,
without twists. If you can’t straighten a seat
belt in your vehicle, take it to an authorized
dealer immediately and have it fixed.
A seat belt that is buckled into the wrong
buckle will not protect you properly. The lap
portion could ride too high on your body,
possibly causing internal injuries. Always
buckle your seat belt into the buckle nearest
you.
A seat belt that is too loose will not protect you
properly. In a sudden stop, you could move too
far forward, increasing the possibility of injury.
Wear your seat belt snugly.
A seat belt that is worn under your arm is
dangerous. Your body could strike the inside
surfaces of the vehicle in a collision,
increasing head and neck injury. A seat belt
worn under the arm can cause internal inju -
ries. Ribs aren’t as strong as shoulder bones.
W e

ar the seat belt over your shoulder so that
your strongest bones will take the force in a
collision.
A shoulder belt placed behind you will not
protect you from injury during a collision. You
are more likely to hit your head in a collision if
you do not wear your shoulder belt. The lap
and shoulder belt are meant to be used
together.
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immedi -
ately. Do not disassemble or modify the seat
b e

lt system. If your vehicle is involved in a
collision, or if you have questions regarding
seat belt or retractor conditions, take your
vehicle to an authorized FCA dealer or autho -
rized FCA Certified Collision Care Program
f a

cility for inspection.
