2009 DODGE GRAND CARAVAN overheating

Gate Operator/Canadian ProgrammingCanadian 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 “Programming
HomeLinkt” Step 3, with the following:
3. Continue to press and hold the HomeLinkt
button
while you press and release - every two seconds
(“cycle”) your hand-held transmitter until HomeLinkt has successfully accepted the frequency signal. The
indicator light will flash slowly and then rapidly when
fully trained.
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under “Programming
HomeLinkt,” earlier in this section.
Security
It is advised to erase all channels before you sell or turn
in your vehicle.
To do this, press and hold the two outside buttons for
20 seconds until the red indicator flashes. Note that all
channels will be erased. Individual channels cannot be
erased.
The HomeLinkt
Universal Transceiver is disabled when
the Vehicle Security Alarm is active.

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 MIL 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 MIL 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 LightThis 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 Section 6
for more 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. UNDERSTANDING YOUR INSTRUMENT PANEL 247

When rear controls are locked by the front system, the
LOCK symbol on the temperature knob is illuminated
and any rear overhead adjustments are ignored.
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 Section 7 of this
manual for proper coolant selection. 322 UNDERSTANDING YOUR INSTRUMENT PANEL

DRIVE — Six-Speed TransaxleThis range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the Electronic
Range Select (ERS) mode by moving the lever — / + and
select the “5” range when frequent transaxle shifting
occurs while using the DRIVE range, such as when
operating the vehicle under heavy loading conditions,
(i.e., in hilly terrain, traveling into strong head winds or
while towing heavy trailers). Under these conditions,
using the “5” range will improve performance and
extend transaxle life by reducing excessive shifting and
heat buildup.
DRIVE — Four-Speed Transaxle
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, select the “3” range
when frequent transaxle shifting occurs while using the
DRIVE range, such as when operating the vehicle under
heavy loading conditions, (i.e., in hilly terrain, traveling
into strong head winds or while towing heavy trailers).
Under these conditions, using the “3” range will improve
performance and extend transaxle life by reducing exces-
sive shifting and heat buildup. CAUTION!
If the transaxle operating temperature exceeds ac-
ceptable limits, the vehicle computer will override
DRIVE and select “5” range (on six-speed transaxles)
or “3” range (on four-speed transaxles) by changing
shift points. This is done to prevent transaxle 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
336 STARTING AND OPERATING

Cooling SystemTo reduce potential for engine and transaxle overheating,
take the following actions:
City Driving
When stopped for short periods of time, put the shift
lever in NEUTRAL but do not increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.) CAUTION!
Towing this vehicle behind another vehicle (flat-
towing with all four wheels on the ground) is not
recommended.
NOTE: If the vehicle requires towing, make sure all four
wheels are off the ground.
408 STARTING AND OPERATING

HAZARD WARNING FLASHERThe 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 action.
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 can help remove this heat.
You can also turn the Temperature Control to maxi-
mum heat, the Mode Control to floor and the Fan
Control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system. 410 WHAT TO DO IN EMERGENCIES

FREEING A STUCK VEHICLEIf 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.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
35 mph (55 km/h) when you are stuck. Do not let
anyone near a spinning wheel, no matter what the
speed. CAUTION!
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 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 shift lever must be in NEUTRAL.
The distance to be traveled must not exceed 100 miles
(160 km).
The towing speed must not exceed 44 mph (72 km/h).

CAUTION!Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you. 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.
