2007 Saab 9-5 Owner's Manual - Page 183

Starting and driving 183 Driving with a spare wheel fitted See page 235. Driving in deep water NOTICE Do not drive in water deeper than 12 inches (30 cm) and do not drive faster than 3-4 mph. Water can otherwise be sucked into the engine. The engine will be seriously damaged if water enters the intake system. Towing the car WARNING • Remember that the brake servo does not operate when the engine is off. Much greater pressure than normal will therefore be required to operate the brake pedal. • Nor does the steering servo operate when the engine is off. The steering will therefore be much heavier than usual. • The towing vehicle should always be heavier than the vehicle on tow. • Never allow passengers to ride in the car being towed. • Always seek professional help if the car needs to be towed. Driving with the trunk lid/tailgate open Avoid driving with the trunk lid/tailgate partly or fully open, since exhaust fumes can be drawn into the cabin. If you must drive with the trunk lid/tailgate open, all windows and the moonroof 3 must be closed and the cabin fan on at its highest speed setting.
