2008 DODGE VIPER differential

Mode Control
Use this control to select the direction
of air flow.
NOTE:The dot between the mode control icons is a mix
position between the two modes.
The mode settings are as follows:
²Recirculation Control
Air is recirculated inside the vehicle. You
may choose between Bi-Level and Panel air
outlets while in this mode. Use this mode to
temporarily block out any outside odors,
smoke, or dust and to cool the interior rapidly upon
initial start up in very hot or humid weather.
²Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to
direct air flow.
²Bi-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.
²Floor
Air is directed through the floor outlets with a
lesser amount through the defrost outlets.

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 inch (9.5 mm) below
the filler plug. If adding axle lubricant, use only the
manufacturer's recommended axle lubricant. Refer to the
ªFluids, Lubricants, and Genuine Partsº 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 the
ªMaintenance Schedulesº in this manual. Change the
lubricant immediately if contaminated with water. See
your authorized dealer for service.
Wheel Bearings
The wheel bearings are permanently sealed. No regular
maintenance is required for these components.
Appearance Care and Protection from Corrosion
Your manufacturer's dealer offers a complete line of
products for cleaning your vehicle. Follow the instruc-
tions on each container.
Commercial Car Washes
We do not recommend taking this vehicle through a
commercial car wash.
