engine overheat DODGE GRAND CARAVAN 2010 5.G Owners Manual

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer if
your vehicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Vehicle”.
Follow the warnings under the Cooling System Pres-
sure Cap paragraph.
4. Speedometer
Indicates vehicle speed.
5. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about 1 mile (1.6 km) with the turn signals on, a continuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
6. High Beam Indicator
This indicator shows that the high beam head-
lights are on. Push the multifunction lever forward
to switch the headlights to high beam and pull toward
yourself (normal position) to return to low beam.
7. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
16. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool. If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
17. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.

Rear Mode Control
Auto Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
Headliner ModeAir comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
Bi-Level Mode Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the BI-LEVEL
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets. Floor Mode
Air comes from the floor outlets.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
314 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
If the transmission operating temperature exceeds
acceptable limits, the vehicle computer will override
DRIVE and select “5” range (on six-speed transmis-
sions) or “3” range (on four-speed transmissions) by
changing shift points. This is done to prevent trans-
mission damage due to overheating.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever to the left (-) or right (+) when
the shift lever is in the DRIVE position, this allows the
selection of the desired top gear. For example, if you shift
the transmission into third gear, the transmission will
never shift above third gear, but can shift down into
second or first gear automatically, when needed.Switching from ERS to DRIVE can be done at any vehicle
speed. To shift from DRIVE mode to ERS mode, move the
shift lever to the left (-) once. The current gear will be
maintained as the top gear. To disable ERS, simply press
and hold the shift lever to the right (+) until “D” is
displayed in the instrument cluster odometer.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.
330 STARTING AND OPERATING

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.(Continued)
CAUTION! (Continued)
•The use of fuel additives which are now being
sold as octane enhancers is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located in the
center of the instrument panel above the radio.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition switch is OFF.
NOTE: With extended use, the Hazard Warning flasher
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, shift the transmission
shift lever into NEUTRAL, but do not increase engine
idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
406 WHAT TO DO IN EMERGENCIES

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then move the shift lever back and forth
between REVERSE and DRIVE. Using minimal accelera-
tor pedal pressure to maintain the rocking motion, with-
out spinning the wheels, is most effective.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween 1st and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.(Continued)
CAUTION! (Continued)
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
NOTE: To improve the vehicle’s traction when starting
off in deep snow, sand or gravel, it may be desirable to
switch the Electronic Stability Program (ESP) to “Partial
Off” mode. Refer to “Electronic Brake Control System” in
“Starting and Operating” for further information.

WHAT TO DO IN EMERGENCIES 425

CAUTION!
•The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions con-
trol device and may seriously reduce engine per-
formance and cause serious damage to the engine.
•Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition.
In the event of engine malfunction, particularly
involving engine misfire or other apparent loss of
performance, have your vehicle serviced promptly.
Continued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.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.
442 MAINTAINING YOUR VEHICLE

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
when the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine. Heat
causes pressure to build up in the cooling system.
To prevent scalding or injury, do not remove the
pressure cap while the system is hot or under
pressure.
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal of Used Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it
to remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean up
any ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine cold, the level of the engine coolant (antifreeze) in
the coolant recovery bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
