188 Car care and technical information Transmission fluid Manual transmission Check and top up the fluid in accordance with the service program. Coolant WARNING • Proceed with caution if the radiator is boiling when you open the hood. Never remove the expansion-tank filler cap when the radiator is boiling. • The cooling system is pressurized - hot coolant and vapor can escape when the filler cap is released. These can cause injury to your eyes and burns. Loosen the cap carefully, and let the engine cool before removing the cap. • Exercise care when adding coolant. Coolant on hot surfaces constitutes a fire risk. The expansion tank is transparent to facilitate checking of the coolant level. When the engine is cold, the coolant must not lie over the KALT/COLD mark on the expansion tank. Automatic transmission Check and top up the fluid in accordance with the service program. Coolant expansion tank If the message "Coolant level low. Refill." is displayed on the SID, check the level of fluid in the expansion tank. Top up, as necessary, with equal parts of clean water and Saab-approved coolant. If the expansion tank is empty when coolant is added, run the engine to normal temperature and top up again, as necessary. IB1338
