check engine light CHRYSLER 300 2018 User Guide

NOTE:A new engine may consume some oil during its
first few 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 indicator often during the
break in period. Add oil as required.
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 the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, press the park brake pedal a second time
and let your foot up as you feel the brake disengage. 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 transmission
is placed in gear, the Brake Warning Light will 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.

222 STARTING AND OPERATING

SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
The “Oil Change Required” message will be displayed in
the instrument cluster and a single chime will sound,
indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and
off-road environment, or is operated predominantly at idle
or only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before your next scheduled service.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering (if equipped) and
fill as needed.
• Check function of all interior and exterior lights.

SERVICING AND MAINTENANCE 341

•Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• 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 necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
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 perform-
ing 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.

SERVICING AND MAINTENANCE 367

Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half-
way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or
service station.
After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when
using high-quality unleaded “Regular”
gasoline having an octane rating of 87 as
specified by the (R+M)/2 method. The
use of higher octane “Premium” gaso-
line will not provide any benefit over “Regular” gasoline in
these engines.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a
cause for concern. However, if the engine is heard making
a heavy knocking sound, see your dealer immediately. Use
