2008 DODGE CARAVAN engine overheat

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 Section 7 of this manual.
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 one mile with the turn signals on, acontinuous 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 Light
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low
beam.
7. Anti-Lock Brake System Light
This light monitors the Anti-Lock Brake Sys-
tem. 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.

15. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come on when turning the key
from OFF to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced at an authorized dealer as soon as possible if this
occurs.16. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a continuous
chime will sound for four minutes. After the chime
turns off, the engine will still be critically hot until the
light turns off.
17. Electronic Throttle Control (ETC.) Light
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected, the light will come on while the
engine is running. Cycle the ignition key when
the vehicle has completely stopped and the gear selector
is placed in the PARK position. The light should turn off.
If the light remains lit with the engine running your
vehicle will usually be drivable, however, see your dealer
for service as soon as possible. If the light is flashing
when the engine is running, immediate service is re-
quired and you may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
232 UNDERSTANDING YOUR INSTRUMENT PANEL

during starting, stays on, or turns on while driving, have
the system inspected by an authorized dealer as soon as
possible.
23. Voltage Light
This light monitors the electrical system voltage.
The light should turn on momentarily as the
engine is started. If the light stays on or turns on while
driving, it indicates a problem with the charging system.
Immediate service should be obtained.
24. Low Fuel Light
When the fuel level reaches approximately 2.0
gallons (7.8 liters) this light will turn on and remain
on until fuel is added.25. Tire Pressure Monitoring Telltale Lamp Ð If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinflation also

HEADLINER Mode
Air 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.
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 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, ªMaintenance Proceduresº, of this manual
for proper coolant selection.
WINTER OPERATION
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7,ªMaintenance Proceduresº, of this manual for proper
coolant selection. Use of the air RECIRCULATION mode
during winter months is not recommended because it
may cause window fogging.
VACATION/STORAGE
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
WINDOW FOGGING
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select DE-
FROST or MIX mode and increase the front blower
speed. Do not use the RECIRCULATION mode without
A/C for long periods, as fogging may occur.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
NEVER leave unattended children alone in a vehicle.
Leaving children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don't leave the key in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
WARNING!
DO NOT leave animals or children inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
WARNING!
Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or sleep
in your car. Accidents can be caused by inadvertently
moving the gear selection lever. Accidents can also be
caused by pressing the accelerator pedal. This may
cause excessive heat in the exhaust system, resulting
in overheating and vehicle fire, which may cause
serious or fatal injuries.
324 STARTING AND OPERATING

under heavy loading conditions, (i.e., in hilly terrain,
traveling into strong head winds or while towing heavy
trailers). Under these conditions, using the ª3º range will
improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
CAUTION!
If the transmission operating temperature exceeds
acceptable limits, the vehicle computer will override
DRIVE and select ª5º range (on six-speed transmis-
sions) or ª3º 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 gear selector lever to the left (-) or right
(+) when the gear selector lever is in the D (Drive)position, this allows the selection of the desired top gear.
For example, if the driver shifts the transmission into 3rd
gear, the transmission will never shift above 3rd gear, but
can shift down to 2nd or 1st gear automatically, when
needed.
Switching from ERS to D-Mode (Drive) can be done at any
vehicle speed. To shift from ªDriveº mode to ªERSº mode,
move gear selector lever to the left (-) once. The current gear
will be maintained as the top gear. To disable ERS, simply
press and hold the gear selector lever to the right (+) until
ªDº 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.

It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
²An 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.
