2020 DODGE GRAND CARAVAN check engine

STARTING AND OPERATING169
The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
When shifting into PARK, firmly move the
gear selector all the way forward and to the
left until it stops and is fully seated.
Look at the transmission gear position
display and verify that it indicates the PARK
position (P).
With brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must exit the vehicle.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous 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 transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition in the
ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
WARNING! (Continued)
CAUTION!
Before moving the transmission gear
selector out of PARK, you must turn the igni -
tion to the ON/RUN mode, and also press
the brake pedal. Otherwise, damage to the
gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a
collision.

STARTING AND OPERATING173
Power Steering Fluid Check
Checking the power steering fluid level at a
defined service interval is not required. The fluid
should only be checked if a leak is suspected,
abnormal noises are apparent, and/or the
system is not functioning as anticipated.
Coordinate inspection efforts through an
authorized dealer. If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids
And Lubricants” in “Technical Specifications”
for the correct fluid type.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
25 mph (40 km/h).
The Speed Control buttons are located on the
right side of the steering wheel.

Speed Control Buttons
NOTE:
In order to ensure proper operation, the Speed
Control System has been designed to shut down
if multiple Speed Control functions are operated
at the same time. If this occurs, the Speed
Control System can be reactivated by pushing
the Speed Control on/off button and resetting
the desired vehicle set speed.
WARNING!
Fluid level should be checked on a level
surface and with the engine off to prevent
injury from moving parts and to ensure
accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended
power steering fluid.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can
damage your power steering components.
Such damage is not covered by the New
Vehicle Limited Warranty.
1 — On/Off
2 — RES (+)
3 — SET (-)
4 — CANCEL
WARNING!
Speed 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 Speed Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door
on the driver’s side of the vehicle. If the gas cap
is lost or damaged, be sure the replacement
cap is for use with this vehicle.

Fuel Filler Cap

NOTE:
The driver's side sliding door cannot be opened
while the fuel door is open. This feature
operates only when the sliding door is fully
closed prior to opening the fuel door. NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
If the gas cap is not tightened properly, the
MIL may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
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
display in the instrument cluster. If this occurs,
tighten the fuel filler cap properly and press the
Trip Odometer button to turn off the message. If
the problem continues, the message will appear
the next time the vehicle is started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the MIL.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap. A poorly
fitting cap could let impurities into the fuel
system and may cause the “Malfunction
Indicator Light (MIL)” to turn on, due to fuel
vapors escaping from the system.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the MIL to
turn on.
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.

Shallow Standing Water

Although your vehicle is capable of driving
through shallow standing water, consider the
following Warnings and Cautions before doing so.

WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION! (Continued)

The numbers inside the Totally Integrated
Power Module (TIPM) cover correspond to the
following table.
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse ele
-
ment.
3 — Blade fuse with a bad/not functional fuse el -
ement (blown fuse).
CAUTION!
When installing the Totally Integrated
Power Module cover, it is important to
ensure the cover is properly positioned and
fully latched. Failure to do so may allow
water to get into the Integrated Power
Module, and possibly result in a electrical
system failure.
When replacing a blown fuse, it is important
to use only a fuse having the correct
amperage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
This 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 “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).An 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 an
authorized dealer, the message can be reset by
referring to the steps described under
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 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) if
the vehicle is operated in a dusty and off road
environment or is operated predominately at
idle or only very low engine RPM. 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 the
oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
and fill as needed.
Check function of all interior and exterior
lights.

232SERVICING AND MAINTENANCE
Checking Oil Level
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every fuel stop. The best time to check the
engine oil level is about five minutes after a fully
warmed engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level within the SAFE
crosshatch marking on the dipstick. Adding one
quart of oil when the reading is at the bottom of
the mark will result in reading the top of the
mark on these engines.
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.
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.
Maintenance-Free Battery
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, nor is periodic maintenance
required.
CAUTION!
Overfilling or underfilling will cause oil
aeration, or loss of oil pressure. This could
damage your engine.
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.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer
-
gency” for further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.
