2005 DODGE RAM 2500 DIESEL climate control

Lock Your Vehicle
Always remove the keys from the ignition and lock all
doors when leaving the vehicle unattended, even in your
own driveway or garage. Try to park your vehicle in a
well-lighted area and never invite theft by leaving ar-
ticles of value exposed.
Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
•Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
•If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
•The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.

The delay interval decreases as you rotate the knob until
it enters the LO continual speed position. The delay can
be regulated from a maximum of about 15 seconds
between cycles, to a cycle every 2 seconds. The delay
intervals will double in duration when the vehicle speed
is 10 mph (16 km) or less.
WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. You might not see other
vehicles or other obstacles. To avoid sudden icing of
the windshield during freezing weather, warm the
windshield with defroster before and during wind-
shield washer use.
Windshield Washers
To use the washer, push in on the washer knob on the end
of the multifunction control lever and hold while spray is
desired. If the washer knob is depressed while in the
delay range, the wiper will operate for several seconds
after the washer knob is released. It will then resume the
intermittent interval previously selected. If the washer
knob is pushed, for a period greater than 1 second, while
in the OFF position, the wiper will wipe approximately
three wipes, after the wash knob is released.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.

NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged, oversized, or have theft
protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.

Temperature Control
The rotary knob at the center
of the control panel controls
the temperature of the inte-
rior air. You can choose your
degree of comfort by rotating
the knob. The coldest tem-
perature setting is to the ex-
treme left (blue region) and
the warmest setting is to the
extreme right (red region) of
the rotation.
Circulation
The cab is designed with features to promote outside air
circulation. There are grilles in the cab back panel. These
are air exhausters that provide the means for regular
exchange of cab air.
Side window demisters direct air flow specifically to the
window glass to help prevent interior fogging of theglass. They are located in the extreme outside upper
edges of the instrument panel. The demisters also pro-
vide extra air ducts for circulation. They are in operation
whenever the Floor, Mix or Defrost modes are in use. To
remove frost from the side windows, it is best to use the
full defrost mode.
NOTE:When you turn off the engine you may hear a
hissing sound from under the hood for a short period of
time. This is a normal condition that occurs if the air
conditioning system has been on. It is not an indication of
a problem with the air conditioning system.
