Car care and technical information 209 Power steering fluid WARNING Do not fill the power steering fluid to above the MAX mark. Too much fluid can result in leakage. Power steering fluid on hot engine components constitutes a fire risk. Check the level of the power steering fluid in the reservoir regularly, in accordance with the service program. The wheels should point forward during the check. Clean around the cap before it is unscrewed. Clean the dipstick. Screw in the cap completely again before checking the level. The oil should lie between the MAX and MIN marks when the oil temperature is about 70°F (+20°C). If the oil is colder the level can be lower, and in higher temperatures the level can be higher, both of which are acceptable. Top up with "Power Steering Fluid CHF 11S". IB501 Air filter WARNING For Service and Repair, parts equivalent to those used by Saab should be used. Be aware that some non standard replacement parts may put you in an unsafe condition, even if they might fit. Power steering fluid reservoir
