2009 DODGE VIPER differential

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.
•Defrost/Floor
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.
•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.
Air Conditioning Control
With the fan control in the ON position, push the
A/C button to turn on the air conditioning com-
pressor. An indicator light above the button shows
that the Air Conditioning compressor is on. Conditioned
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 Axle
Axle Lubricant Level Check
Check the exterior of the axle for evidence of gear oil
leakage every 12 months or 6,000 miles (10 000 km). This
check should be made with the vehicle level and sup-
ported by the suspension, with the vehicle on the ground
or raised on an axle and wheel type hoist. The axle
lubricant level should be between the bottom of the filler
plug and a point approximately 3/8 in (9.5 mm) below
the filler plug. If adding axle lubricant, use only the
manufacturer’s recommended axle lubricant. Refer to the
“Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.
NOTE:The Limited Slip Differential requires that a
friction control additive be added when draining and
refilling the axle lubricant.
Change Axle Lubricant
Drain and fill the axle at the intervals specified in
“Maintenance Schedules” in Section 8 of this manual.
Change the lubricant immediately if contaminated with
water. See your authorized dealer for service.
Appearance Care And Protection From Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
