Removal and Installation

1. WARNING: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension service switch. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.

If equipped, turn the air suspension service switch to the OFF position.
2. Check the brake fluid level in the brake master cylinder reservoir.
^ If required, remove the fluid until the brake master cylinder reservoir is half full.
