Water or mud can make the brake linings slippery, resulting in delayed braking effect. CAUTION Engine damage will occur if water is drawn into the air cleaner. If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components. Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result in electrical malfunctions. If the engine has been stopped while the vehicle is in water, do not attempt to restart it. Have the vehicle towed out of the water. Engine and cooling system Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine. Maintain a low speed when driving with a trailer up long, steep hills. Do not turn the engine off immediately when stopping after a hard drive. WARNING The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off. Remove any auxiliary lights from in front of the grille when driving in hot weather conditions. Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become too high. Conserving electrical current Keep the following in mind to help minimize battery drain: When the engine is not running, avoid using ignition mode II . Many electrical systems (the audio system, the optional navigation system, power windows, etc) will function in ignition modes 0 and I . These modes reduce drain on the battery. Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not running could result in the battery being completely drained. The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which drains the battery. 194 05 During your trip Driving recommendations Before a long distance trip It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before driving long distances. Your retailer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for your use in the event that problems occur. As a minimum, the following items should be checked before any long trip: Check that engine runs smoothly and that fuel consumption is normal. Check for fuel, oil, and fluid leakage Have the transmission oil level checked.
