to check the fluid level, park on a flat level surface, & with engine running put the suspention height control on to maximum height setting,allow the car time to settle at its maximum height ,then looking in the engine bay,the hydraulic reservoir is a black plastic container at the back on the right hand side, it has a lot of rubber pipes attached to it,on the top is a small clear plastic dome with 2 red lines on it, inside the dome is a yellow plastic float, this float should be between the the two lines,if the level is correct, if not remove the cap next to the dome & top up with clean L H M fluid DO NOT use any other fluid in these systems as it will ruin the rubber pipes & seals & leave you with a big repair bill
