warning light CHRYSLER 300 2021 Owner's Manual

76 GETTING TO KNOW YOUR INSTRUMENT PANEL
When the engine is running, the MIL may flash to
alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced
by an authorized dealer as soon as possible if this
occurs.Service AWD Warning Light — If Equipped
This warning light will turn on to indicate
the All Wheel Drive (AWD) system is not
fu
nctioning properly and that service is
required. Contact an authorized dealer.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
W a
rning System. Contact an authorized
dealer for service
Ú page 146.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
ti
re pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
m e

ntioned above, the display will show the
indications corresponding to each tire. Each tire, including the spare (if provided), should
b
e

checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
e q

uipped with a TPMS that illuminates a low tire
pressure warning light when one or more of your
tires is significantly underinflated. Accordingly,
when the low tire pressure warning light
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated
tire causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability.
WARNING!
A malfunctioning catalytic converter, as refer -
enced above, can reach higher temperatures
t h
an in normal operating conditions. This can
cause a fire if you drive slowly or park over flam -
mable substances such as dry plants, wood,
c a

rdboard, etc. This could result in death or seri -
ous injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the
vehicle control system. It also could affect fuel
economy and driveability. If the MIL is flashing,
severe catalytic converter damage and power
loss will soon occur. Immediate service is
required.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

GETTING TO KNOW YOUR INSTRUMENT PANEL 77
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
warning light.
Your vehicle has also been equipped with a TPMS
ma

lfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
warning light. When the system detects a
malfunction, the warning light will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the
malfunction indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction warning light after replacing one or
more tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.

size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

GETTING TO KNOW YOUR INSTRUMENT PANEL 79
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as engine
emissions well within current government
regulations.
If any of these systems require service, the OBD II
sy

stem will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be drivable and not need towing, see an authorized
dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system
Ú page 121.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies
th

e Malfunction Indicator Light (MIL) is
functioning and is not on when the
engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may n
ot
be ready if your vehicle was
recently serviced, recently had a dead battery or a
battery replacement. If the OBD II system should
be determined not ready for the I/M test, your
vehicle may fail the test.
Your vehicle has a simple ignition actuated test,
w h

ich you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:

1. Cycle the ignition switch to the ON position, b
ut do not crank or start the engine.

NOTE:
If you crank or start the engine, you will have to
s t
art this test over.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected to the
OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
i n
cluding personal information.

When the parking brake is applied with the ignition
switch in the ON/RUN position, the Brake Warning
Light in the instrument cluster will illuminate.
NOTE:

When the parking brake is applied and the trans -
mission is placed in gear, the Brake Warning Light
w i
ll flash. If vehicle speed is detected, a chime will
sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.

This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the
f r

ont wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK. The parking brake
should always be applied whenever the driver is
not in the vehicle.
AUTOMATIC TRANSMISSION
NOTE:
You must press and hold the brake pedal while
s h
ifting out of PARK.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible injury
or damage.
When exiting the vehicle, always remove the
key fob from the ignition and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
d a

ngerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
When exiting the vehicle, always make sure
the keyless ignition node is in the OFF mode,
remove the key fob from the vehicle and lock
the vehicle.
Do not leave the key fob in or near the vehicle
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
WARNING!
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.
CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Never use the PARK position as a substitute

92 STARTING AND OPERATING
FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:
This system may take some time to return to full
f u
nctionality after a battery disconnect.
POWER STEERING
The Electric Power Steering system will give you
good vehicle response and increased ease of
maneuverability in tight spaces. The system will
vary its assist to provide light efforts while parking
and good feel while driving. If the electric steering
system experiences a fault that prevents it from
providing assist, you will still have the ability to
steer the vehicle manually. Alternate electric power steering efforts can be
s
e

lected through the Uconnect system
Ú page 122.
If the Electric Power Steering Fault
Warning Light is displayed and the
“ S

ERVICE POWER STEERING” or the
“POWER STEERING ASSIST OFF –
SERVICE SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for service
Ú page 71.
NOTE:

Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substan
-
tial increase in steering effort, especially at low
s p

eeds and during parking maneuvers.

If the condition persists, see an authorized
dealer for service.
If the Electric Power Steering Fault Warning Light is
di
splayed and the “POWER STEERING SYSTEM
OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that
extreme steering maneuvers may have occurred
which caused an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the Electric Power Steering Fault
Warning Light and message turn off.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control system takes
over accelerator operations at speeds greater than
25 mph (40 km/h), or 20 mph (32 km/h)
de

pending on engine size and axle ratio.
The Cruise Control buttons are located on the right
si
de of the steering wheel.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

STARTING AND OPERATING 93

Cruise Control Buttons

To Activate
Push the on/off button to activate the Cruise
Control. “CRUISE CONTROL READY” will appear in
the instrument cluster display to indicate the
Cruise Control is on. To turn the system off, push
the on/off button a second time. “CRUISE
CONTROL OFF” will appear in the instrument
cluster display to indicate the Cruise Control is off.
The system should be turned off when not in use.
To Set A Desired Speed
Turn the Cruise Control on. When the vehicle has
reached the desired speed, push and release the
SET (+) or SET (-) button. Release the accelerator
and the vehicle will operate at the selected speed.
Once a speed has been set, a message “CRUISE
CONTROL SET TO MPH (km/h)” will appear
indicating the set speed. A cruise indicator lamp,
along with set speed will also appear and stay on
in the instrument cluster when the speed is set.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase
sp

eed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
s u
bsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
Metric Speed (km/h)
Pushing the SET (+), or SET (-) button once will
result in a 1 km/h speed adjustment. Each
s u
bsequent tap of the button results in an

(Continued)
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC button,
or normal brake pressure will deactivate the Cruise
Control system without erasing the set speed from
memory.
The following conditions will also deactivate the
Cr

uise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs Pushing the on/off button or placing the ignition in
t
h

e OFF position erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently
Ú page 92.
ACC will allow you to keep Cruise Control engaged
i n

light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward facing
camera designed to detect a vehicle directly ahead
of you.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of
the Adaptive Cruise Control and Forward Colli -
sion Warning systems.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 254.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
d r
iver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
r e

quired while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
s e

rious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.

98 STARTING AND OPERATING
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
The ACC will bring the vehicle to a complete stop
while following a vehicle in front and hold the
vehicle for two seconds in the stop position. If
the vehicle in front does not start moving within
two seconds, the ACC system will display a
message that the system will release the brakes
and that the brakes must be applied manually.
An audible chime will sound when the brakes
are released.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.

Distance Settings

To increase the distance setting, push the
D i

stance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer). To decrease the distance setting, push the
D
i

stance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
ma
intain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the ACC Set With Target
Detected Indicator Light, and the system will adjust
the vehicle speed automatically to maintain the
distance setting, regardless of the set speed.
The vehicle will then maintain the set distance
u n

til:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú page 96.
The maximum braking applied by ACC is limited;
h ow

ever, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the ACC
s y
stem applies the brakes.
A Proximity Warning will alert the driver if ACC
pr
edicts that its maximum braking level is not
sufficient to maintain the set distance. If this
