156 Starting and driving Automatic transmission 1, fault indicator Overheated transmission fluid NOTICE If the control module has actuated the Limp-home function for the automatic transmission, the car will remain in 5th gear when D is selected, making it very sluggish. Select position L to prevent unnecessary wear on the transmission. The transmission then starts in 2nd gear. Once the car is moving you can select position D. When the indicator light is on, the car must not be driven with a caravan or trailer attached. If the automatic-transmission fluid should overheat, the following message will appear on the SID: "Gearbox too hot. Make a safe stop." In this event, stop the car in a suitable place, switch off the engine and open the hood. Wait for several minutes then turn on the ignition to check that the message has gone out. When driving subsequent to the transmission fluid overheating, select a gear in which the engine speed is about 3,000 rpm. Overheating of the automatic-transmission fluid can occur when the car is towing a heavy load, such as a camping trailer in hilly country. High ambient temperatures can also increase the temperature of the transmission fluid or the oil cooler may be faulty. Contact a workshop. We recommend that you contact an authorized Saab dealer (see also page 176). If "Automatic transmission 1, fault indicator" 4 7 appears on the main instrument panel, the system has detected a fault in the automatic transmission or its control module (see page 62). This also means that the Limp-home mode has been selected, to guard against further damage being done to the transmission. In this mode, the automatic transmission starts in 5th gear, and gear changes (if necessary) will have to be made manually. Stop the car in a safe place. Switch off then restart the engine. If the fault is intermittent, the transmission will operate as normal despite the fault indicator being on. Have the car checked at a workshop. We recommend that you contact an authorized Saab dealer. It is not possible to select the SPORT or Sentronic mode when the Limp-home mode is active. Gear changes must be made manually. The following gears will be engaged in the respective selector positions when the automatic transmission is in Limp-home mode: Position Gear R Reverse D 5th M 5th L 2nd
