2009 Ram 1500 Owner's Manual

Vacation/Storage
Any time 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
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold weather. To clearthe 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, can cause
odor, 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.

308 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
•Accidents can be caused by inadvertently moving
the shift lever or 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.
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
Normal Starting
Normal starting of either a warm or cold 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 fails to start within
10 seconds, turn the key to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of PARK.5
STARTING AND OPERATING 309

Tip Start Feature
Do notpress the accelerator. Turn the ignition key briefly
to the START position and release it. The starter motor
will continue to run but will automatically disengage
when the engine is running.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, 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.
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.
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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. Refer
to “Jump Starting” in Section 6 of this manual.
