MAINTENANCE
Active Descent Control (ADC) Fluid
If your vehicle is equipped with Active Descent Control, there are two
fluid levels that must be maintained (demand drive fluid and ADC
fluid). See page 77 for demand drive fluid maintenance.
Check and change the ADC fluid level at the intervals outlined in the
Periodic Maintenance Chart beginning on page 68. Maintain the fluid
level between the minimum and maximum marks on the reservoir. We
recommend the use of Polaris ADC Fluid. See page 125 for the part
numbers of Polaris products.
NOTICE: Do not use brake fluid. Brake fluid will damage rubber components in
the hydraulic system.
1. Remove the front rack.
2. View the fluid level in the
reservoir.
3. If the level is below the
minimum mark, remove
the cap and add the
recommended fluid.
4. Reinstall the cap.
5. Reinstall the front rack.
