Starting and driving 183 Driving in hot climates Always check the coolant level before starting a journey. When the engine is cold, the coolant must not lie above the KALT/COLD mark on the expansion tank (boundary between the upper and lower sections of the tank). At the end of a journey, allow the engine to idle for 2-3 minutes before switching it off. If the needle on the temperature gauge enters the red zone, the following message will be shown on the SID: Hot engine. Make a safe stop. Run engine on idle. 1 Stop the car but do not switch off the engine. Do not remove the cap on the cooling system expansion tank, even if the tank is empty. The engine temperature should decrease. If the temperature continues to rise with the engine idling, the engine must be switched off. 2 If the engine is idling and the needle on the temperature gauge falls, wait until a normal temperature is shown (about in the middle of the scale) before switching off the engine. If the coolant needs to be topped up, carefully unscrew the expansion tank cap. Fill as required with a mixture of 50 % antifreeze and 50 % clean water. Use an antifreeze approved by Saab. WARNING • Exercise care when opening the hood if the engine is overheated. Never remove the expansion tank cap completely when the engine is hot. • The cooling system is pressurized hot coolant and vapour can escape. These can cause injury to your eyes and burns. Open the cap slowly to release the pressure before removing it. 3 Have the car's cooling system checked at a Saab dealer.
