i was just looking through the manual of the 03 to 06 and this is what i came across
Warning:
. Use only the recommended brake fluid. Other brake fluids may cause the rubber seals to deteriorate, causing leakage and poor brake performance.
. Refill with the same type of brake fluid. Mixing brake fluids may result in a harmful chemical reaction and lead to poor performance.
. Be careful that water does not enter the master cylinder when refilling. Water will significantly lower the boiling point of the brake fluid and may result in vapor lock.
im not sure if this helped you or not but its just something i came across
