2008 DODGE CARAVAN overheating

Using HomeLinkt
To operate, simply press and release the programmed
HomeLinktbutton. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc. The hand-held transmitter of the device may also be
used at any time.
Reprogramming a Single HomelinktButton
To reprogram a channel that has been previously trained,
follow these steps:
1. Turn the ignition switch to the ON/RUN position.
2. Press and hold the desired HomeLinktbutton until
the indicator light begins to flash after 20 seconds.Do not
release the button.
3.Without releasing the button,proceed with Program-
ming HomelinktStep 2 and follow all remaining steps.
GATE OPERATOR/CANADIAN PROGRAMMING
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission ± which may not be long enough for HomeLinkt
to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace ªProgramming
HomeLinktº Step 3, with the following:
3. Continue to press and hold the HomeLinktbutton
while you press and release - every two seconds
(ªcycleº) your hand-held transmitter until HomeLinkt

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.

HAZARD WARNING FLASHER
The hazard flasher switch is located in the center of
the instrument panel below the radio.
To engage the Hazard Warning Flashers, depress the
switch on the instrument panel. When the Hazard Warn-
ing Switch is activated, all directional turn signals will
flash on and off to warn oncoming traffic of an emer-
gency. Push the switch a second time to turn off the
flashers.
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 Flashers will continue to operate even
though the ignition switch is OFF.NOTE:With extended use, the Hazard Warning Flash-
ers 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.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, shift the transmission
gear selector 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
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
410 WHAT TO DO IN EMERGENCIES

CAUTION!
Racing 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 35 mph (55 km/h).
TOWING A DISABLED VEHICLE
Towing With The Ignition Key
Your vehicle may be towed under the following condi-
tions: The gear selector lever must be in NEUTRAL, the
distance to be traveled must not exceed 100 mi (160 km),
and the towing speed must not exceed 44 mph (72
km/h). Exceeding these towing limits may cause a trans-
mission geartrain failure. If the transmission is not op-
erative, or if the vehicle is to be towed more than 100 mi
(160 km), the vehicle must be towed with the front
wheels off the ground.
CAUTION!
²Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
²Always use wheel lift equipment when towing
from the front. The only other approved method of
towing is with a flat bed truck.
²Do not tow the vehicle from the rear. Damage to
the rear sheet metal, liftgate and fascia will occur.
428 WHAT TO DO IN EMERGENCIES

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer's specifications, should be ob-
tained immediately.To minimize the possibility of catalyst damage:²Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
