Starting and driving 181 Driving in hot weather • Always check the coolant level before starting a journey. The level should be just below the MAX mark. • At the end of a journey, if the engine has worked hard, allow it to idle for two or three minutes before switching it off. If the needle on the temperature gauge enters the red zone: 1 Bring the car to a standstill but leave the engine running. Do not remove the cap on the expansion tank even if the tank is empty. If the needle on the temperature gauge continues to rise while the engine is idling, switch off the engine. 2 Wait until the needle has dropped back to indicate normal temperature (roughly midway, in the white zone) before stopping the engine. If the coolant needs topping up, unscrew the cap on expansion tank carefully. Top up, as necessary, ideally with a 50/50 mixture of Saab-approved coolant and water. If only water is available, use that, but remember to have the coolant mixture checked as soon as possible. Towing a trailer Trailer hitch attachment Trailer hitch attachments are available as accessories. These are designed for a maximum trailer weight of 3500 lbs. (1588 kg), see also page 259. Use only the electrical trailer hitch socket provided in the trailer hitch kit. Saab recommends: • Use a Saab original hitch kit attachment which is designed and tested by Saab. • Consult your Saab dealer regarding the appropriate hitch kit for your car. 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 vapor can escape. These can cause injury to your eyes and burns. Open the cap slowly to release the pressure before removing it. 3 As soon as possible, have the cooling system checked by an authorized Saab dealer. NOTICE Use only a genuine Saab trailer hitch and wiring, since other wiring methods can cause expensive damage to the car's body and electrical system. Consult an authorized Saab dealer for guidance on how to connect the trailer hitch electrical system.
