check engine light DODGE GRAND CARAVAN 2010 5.G User Guide

NOTE:Moving the shift lever into third gear (with
four-speed transmission) or fifth gear (with six-speed
transmission) while operating the vehicle under heavy
operating conditions will improve performance and ex-
tend transmission life by reducing excessive shifting and
heat build up. This action will also provide better engine
braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:
•Check the automatic transmission fluid level before
towing.
•The six-speed automatic transmission is sealed and
requires an authorized dealer to check the transmis-
sion fluid.
Electronic Speed Control – If Equipped
•
Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
402 STARTING AND OPERATING

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 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 engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer or a
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
7
MAINTAINING YOUR VEHICLE 433

“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until aclickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
Press the odometer reset button to turn the message off.
If the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL light off.
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 Mainte-
nance (I/M), this check verifies the “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 notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. 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 key-actuated test,
which 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. Turn the ignition switch to the ON position, but do not
crank or start the engine.
434 MAINTAINING YOUR VEHICLE

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 fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the engine
compartment and should be checked at regular intervals.
Fill the reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system for a few
seconds to flush out any residual water. The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. MOPAR All
Weather Windshield Washer Solution or equivalent, used
with water as directed on the container, aids cleaning
action, reduces the freezing point to avoid line clogging,
and is not harmful to paint or trim.
448 MAINTAINING YOUR VEHICLE

Once A Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir, the
brake master cylinder, the power steering and the
transmission and add as needed.
•Check all lights and other electrical items for correct
operation.At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
