2006 DODGE GRAND CARAVAN engine

Rear Mode Control
The Rear Mode Control, located in
the headliner near the center of
the vehicle can be used to select
between Auto, Headliner, Bi-
Level and Floor modes.
Auto Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
Floor Mode
Air comes from the floor outlets. 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.
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 vane knob on the outlets to
one side will shut off the air flow.
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 ethylene294 UNDERSTANDING YOUR INSTRUMENT PANEL

glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure 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, Maintenance
Procedures, 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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com-
pressor 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  defrost 
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.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow. UNDERSTANDING YOUR INSTRUMENT PANEL 295

Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates. Washer Fluid Reservoir UNDERSTANDING YOUR INSTRUMENT PANEL 299

STARTING PROCEDURES
CAUTION!Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear. 2.4L Engine
Normal Starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the “ START ” position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the “ OFF ” position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Cold Weather (Below 0 ° Cor32 ° F) or High Altitude
(Above 4,000 feet at all temperatures). If engine has not
been started within past 3 to 4 hours, slightly depress and
hold the accelerator pedal before attempting to start a
cold engine. Turn the key to the “ START ” position. When
the engine starts, release first the key, then the accelerator
pedal. If the engine fails to start within 15 seconds,
discontinue cranking and return the key to the “ OFF ”
position. Repeat the starting procedure.304 STARTING AND OPERATING

Extremely Cold Weather (below
29 ° Cor
20 ° F). To
insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
WARNING!Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully. WARNING!Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
If Engine Fails to Start
If the engine fails to start after you have followed the
“ NORMAL STARTING ” , “ COLD WEATHER ” or “ HIGH
ALTITUDE ” procedures, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while cranking the engine. This should clear any excess
fuel in case the engine is flooded. STARTING AND OPERATING 305

CAUTION!To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly. Do not overspeed engine.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “ NORMAL STARTING ” , “ COLD
WEATHER ” or “ HIGH ALTITUDE ” procedure should be
repeated. After Starting
The idle speed will automatically decrease as the engine
warms up.
