2004 DODGE VIPER air conditioning

RADIO ANTENNA
The radio antenna is located in the windshield.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular phone
in your vehicle can cause erratic or noisy performance 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 ªclearº by the repositioning of the an-
tenna, it is recommended that the radio volume be turned
down or off during cellular phone operation.
VENTILATION
When the ventilation mode is selected, outside air comes
through the panel outlets. Air will enter the vehicle with
or without the blower in operation.
CLIMATE CONTROLS
The Air Conditioning System allows you to balance the
temperature, amount and direction of the air circulating
throughout the vehicle.
90 UNDERSTANDING YOUR INSTRUMENT PANEL

Panel
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct air
flow.
Bi-Level
Air is directed through the instrument panel and
floor outlets. A small amount of air is also directed
through the defrost outlets.
NOTE:There is a varying temperature differential be-
tween the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
Floor
Air is directed through the floor outlets with a
lesser amount through the defrost outlets.Floor/Defrost
Air is directed through the windshield defrost and
the floor outlets. This setting works best in cold or
snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
Windshield Defrost
Air is directed through the windshield defrost
outlet. Use this mode with maximum fan and
temperature settings for best windshield defrosting.
NOTE:The air conditioning compressor operates in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the Defrost
mode only when necessary.
A/C Pushbutton
With the fan control in the ON position, pushing
the A/C button turns on the air conditioning
compressor. An indicator light above the button
92 UNDERSTANDING YOUR INSTRUMENT PANEL

shows that the Air Conditioning compressor is on. Con-
ditioned air is now directed through the outlets selected.
Pushing the button a second time turns the compressor
OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. A light
above the button shows that the Rear Defroster is On.NOTE:The defroster turns off automatically after 15
minutes of operation. Each later activation will allow 71¤2
minutes of operation.
CAUTION!
To avoid damaging the electrical conductors, do not
use scrapers, sharp instruments, or abrasive window
cleaners on the interior surface of the rear window.
Labels can be peeled off by soaking with warm
water.

²In city trafficÐWhile moving, shift into the highest
gear possible to reduce engine RPM.
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 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 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 cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
If your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to
call a service center for service. If you decide to look
under the hood yourself, see Section 7 of this
manual. Follow the warnings under the Radiator
Cap paragraph.
WHAT TO DO IN EMERGENCIES 133
6

1. Press the driver's door exterior handle to wake up the
vehicle.
2. If the door does not open (vehicle is armed) press the
remote keyless entry unlock button to unlock the vehicle.
3. Press the driver's door exterior handle again to open
the door.
4. Cycle the Ignition to ON/RUN. If the ignition is NOT
cycled to ON/RUN, then the vehicle will re-enter Battery
Save Mode 45 seconds after the driver's door is closed.
Air Conditioner
Check the air conditioning system operation at the start
of the warm weather season.
NOTE:If air conditioning operation seems to be lower
than expected, check the front of the A/C condenser,
located in front of the radiator for dirt or insect accumu-
lation. Clean with a gentle water spray as required. Frontend fascia protectors may reduce air flow to the con-
denser and radiator, reducing A/C and engine cooling
performance.
WARNING!
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal injury
or damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere. The manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recycling and recovery equipment that meets
SAE standard J1991.
160 MAINTAINING YOUR VEHICLE

When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle.
Points to Remember
²
Do not overfill the bottle.
²Check coolant freeze point in the coolant bottle. If
antifreeze needs to be added, contents of the coolant
bottle also must be protected against freezing.
²If frequent coolant additions are required, or if the
level in the bottle does not drop when the engine cools,
the cooling system should be pressure tested for leaks.
²Maintain coolant concentration of 50% ethylene glycol
(minimum) with recommended antifreeze for proper
corrosion protection of your engine that contains alu-
minum components.
²Make sure that the radiator and bottle overflow hoses
are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean
also.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling suggest deterioration of the rub-
ber. Pay particular attention to those hoses nearest to
high heat sources such as the exhaust manifold. Inspect
170 MAINTAINING YOUR VEHICLE

Carpeting
Vacuum your carpeting regularly to prevent a soil
buildup. Shampoo soiled carpeting with a reliable uphol-
stery cleaner, using a natural sponge or soft bristle brush.
After carpeting dries, vacuum it thoroughly.
Underbody Maintenance
The corrosive materials used for ice and snow removal or
dust control may accumulate on the underbody of your
vehicle. If not removed, these materials may accelerate
rusting and deterioration of underbody components such
as fuel lines, frame, floor pan, exhaust system, etc.
At least twice during the winter months hose down the
wheel wells and underside of the vehicle. Make sure you
remove mud and salt from panels, crevices and ledges,
and that all drain holes and channels are free of debris.
NOTE:You can do more harm by hosing off the vehicle
without removing caked mud and debris.
The frame of your Viper is galvanized for rust-through
protection. It is also dipped in a black E-Coat to protect the
welded areas. Avoid any scratches through to bare metal.
Commercial Car Washes
We do not recommend that you take your Viper through
a commercial car wash.
In the event that you do take your Viper to a commercial
car wash, move the Heater/Air Conditioning blower
control to the lowest setting. This will prevent the possi-
bility of water entering the system.
CAUTION!
The tires on your Viper are wider than the guide
tracks on most washes and the low ground clearance
of your vehicle may not be compatible with some car
wash equipment. You could damage your vehicle.
