MAINTENANCE Active Descent Control (ADC) Fluid Fluid Change 1. Position the vehicle on a level Bleeder surface. Before performing the Screw fluid change, allow the vehicle Cap to sit for at least 30 minutes. Bleeder 2. Thoroughly clean the areas Valve Screw around and on the ADC reservoir and bleeder valves (one on each side of the differential). 3. Remove the reservoir cap and diaphragm assembly. Use a shop towel or suction tool to remove debris from the fluid and reservoir. Debris in the reservoir may result in inadequate bleeding and reduced performance of the system. 4. Fill the reservoir to the maximum line with fresh fluid. 5. Remove the protective caps from the bleeder valves. 6. Slowly loosen one of the bleeder valve screws (turn counter-clockwise) and allow fluid and trapped air to flow from the fitting. Tighten the screw when clean fluid begins to flow. Repeat this step for the remaining valve. IMPORTANT: Close the bleeder valve screws before the reservoir fluid level drops below the minimum fill line. Adding fluid to an empty reservoir will result in trapped air. If the level drops below the minimum line, add fluid to the maximum line and repeat step 6 before proceeding. 7. Torque the bleeder valve screws to 80 in. lbs. (9 Nm). Reinstall the bleeder valve caps. 8. Add fresh ADC fluid to the reservoir until the level is between the minimum and maximum marks. Make sure the reservoir is free of debris. 9. Reinstall the cap securely. Clean up any drips or spills. 83

MAINTENANCE
Active Descent Control (ADC) Fluid
Fluid Change
1.
Position the vehicle on a level
surface. Before performing the
fluid change, allow the vehicle
to sit for at least 30 minutes.
2.
Thoroughly clean the areas
around and on the ADC
reservoir and bleeder valves
(one on each side of the
differential).
3.
Remove the reservoir cap and
diaphragm assembly. Use a
shop towel or suction tool to
remove debris from the fluid
and reservoir. Debris in the
reservoir may result in
inadequate bleeding and
reduced performance of the
system.
4.
Fill the reservoir to the maximum line with fresh fluid.
5.
Remove the protective caps from the bleeder valves.
6.
Slowly loosen one of the bleeder valve screws (turn counter-clock-
wise) and allow fluid and trapped air to flow from the fitting.
Tighten the screw when clean fluid begins to flow. Repeat this step
for the remaining valve.
IMPORTANT:
Close the bleeder valve screws before the reservoir fluid level
drops below the minimum fill line. Adding fluid to an empty reservoir will result in
trapped air. If the level drops below the minimum line, add fluid to the maximum
line and repeat step 6 before proceeding.
7.
Torque the bleeder valve screws to 80 in. lbs. (9 Nm). Reinstall the
bleeder valve caps.
8.
Add fresh ADC fluid to the reservoir until the level is between the
minimum and maximum marks. Make sure the reservoir is free of
debris.
9.
Reinstall the cap securely. Clean up any drips or spills.
