The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service technician only. Check all lights, including high beams. Reflective warning triangles are legally required in some states/provinces. Have a word with your Volvo retailer if you intend to drive in countries where it may be difficult to obtain the correct fuel. Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider snow tires. 1 To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid level inspected by a qualified Volvo service technician. 132 06 Starting and driving Fuel requirements Octane rating MINIMUM Volvo recommends premium for best performance, but using 87 octane or above will not affect engine reliability. Volvo engines are designed to achieve rated horsepower, torque, and fuel economy performance using premium 91 octane fuel. In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended periods at higher altitudes than normal, it may be advisable to switch to higher octane fuel RECOMMENDED
