tow CHRYSLER 300 2010 1.G Repair Manual

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 automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
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. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emissions 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 engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will appear in the odometer or a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the

3. Install the new filter with arrows pointing in the
direction of airflow, which is toward the rear of the
vehicle (text and arrows on the filter will indicate this).
Refer to “Maintenance Schedule” for the proper mainte-
nance intervals.Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease, such as
MOPARSpray White Lube or equivalent to assure
quiet, easy operation and to protect against rust and
wear. Prior to the application of any lubricant, the parts
concerned should be wiped clean to remove dust and
grit; after lubricating excess oil and grease should be
removed. Particular attention should also be given to
hood latching components to ensure proper function.
When performing other underhood services, the hood
latch, release mechanism and safety catch should be
cleaned and lubricated.

The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant or equivalent, directly into the
lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc. NOTE:
Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any condition is
present please proceed to clean wiper blades with humid
cloth removing any debris that may be affecting its
function.
Adding Washer Fluid
The windshield washer and the headlight washer (if
equipped) share the same fluid reservoir. The fluid
reservoir is located in the front of the engine compart-
ment. Be sure to check the fluid level in the reservoir at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and operate the
system for a few seconds to flush out the residual water.
When refilling the washer fluid reservoir, apply some
washer fluid to a cloth or towel and wipe the wiper
blades clean. This will help blade performance.

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately. To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.

•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use MOPARTouch Up Paint or equivalent on
scratches as soon as possible. Your authorized dealer
has touch up paint to match the color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome-plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil and/or excessive brake dust, use MOPAR
Wheel Cleaner or equivalent or select a nonabrasive,
non-acidic cleaner. Do not use scouring pads, steel wool,
a bristle brush, or metal polishes. Only MOPAR or
equivalent is recommended. Do not use oven cleaner. Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.
Stain Repel Fabric Cleaning Procedure – If
Equipped
Stain Repel seats may be cleaned in the following man-
ner:
•Remove as much of the stain as possible by blotting
with a clean, dry towel.
•Blot any remaining stain with a clean, damp towel.
•For tough stains, apply MOPAR
Total Clean or a mild
soap solution to a clean, damp cloth and remove the
stain. Use a fresh, damp towel to remove soap residue.
•For grease stains, apply MOPAR Multi-Purpose
Cleaner or equivalent to a clean, damp cloth and
remove the stain. Use a fresh, damp towel to remove
soap residue.

To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPARGlass Cleaner or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or the right rear
quarter window equipped with the radio antenna. Do
not use scrapers or other sharp instrument that may
scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or rag that you are using. Do not spray cleaner
directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag or micro-fiber towel. A mild
soap solution may be used, but do not use high alcohol
content or abrasive cleaners. If soap is used, wipe clean
with a clean damp rag.
2. Dry with a soft tissue.
Seat Belt Maintenance
Do not bleach, dye, or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use MOPAR Total Clean, a
mild soap solution, or lukewarm water. Do not remove
the belts from the vehicle to wash them.

MAINTAINING YOUR VEHICLE 459

Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Cleaning the Center Console Cupholders
Clean with a damp cloth or towel using a mild detergent
with the cupholder in the center console.
NOTE:The cupholder cannot be removed.
