95_US_MY09.book Page 66 Tuesday, April 15, 2008 11:03 AM 66 Instruments and controls NOTICE If the needle, despite the above action, enters the red zone, stop the car immediately, let the engine idle. If the needle stays in the red zone, stop the engine. Check fuse 1 (radiator fan) in the fuse panel under the hood, see page 218. If the needle repeatedly enters the red zone, stop the car as soon as it is safe to do so and check the coolant level by looking at the level visible through the plastic tank - do not remove the cap. If the coolant level falls below the MIN mark, the Saab Information Display (SID) will display the message "Coolant level low. Refill.". WARNING Never open the cap of the expansion tank completely when the engine is hot, open with care. The pressure in the cooling-system can cause hot coolant and steam to be released. Failure to heed this warning may result in personal injury. Temperature gauge The temperature gauge shows the temperature of the coolant. The needle should be in the middle of the scale when the engine is at normal operating temperature. If the needle approaches the red zone, which can occur in very hot weather or when the engine is under a heavy load, drive in the highest gear possible, keep the engine revs low and avoid shifting down.
