At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed than with the air conditioning off and the windows open. Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically. Other factors that decrease gas mileage are: Dirty air cleaner Dirty engine oil and clogged oil filter Dragging brakes Incorrect front end alignment Some of the above mentioned items and others are checked at the standard maintenance intervals. Weight distribution affects handling At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo area, the less the tendency to understeer. WARNING! Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases entering the passenger compartment. If the trunk must be kept open for any reason, Close the windows Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its highest setting. CAUTION! Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18 inches (48 cm). Handling, roadholding Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to pg. 99 Starting and driving General information the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed so that capacity weight or maximum permissible axle loads are not exceeded. Cold weather precautions If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting: Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection. This gives protection against freezing down to -31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze is not approved by Volvo. Different types of antifreeze must not be mixed. Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator. Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. In addition, in extremely cold weather conditions it is worthwhile to add fuel line de-icer before refueling. The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
