Starting and operating same tire size, construction, brand, and load range as the original tires. The recommended tire sizes and pressure are provided on the tire label, which can be found on the driver's side door jamb under the latch. Remember to drive with care at all times regardless of the type of tires on your vehicle. J Tire chains CAUTION Tire chains cannot be fitted with P205/60R15 tires for OUTBACK and P205/55R16 tires for RS because of lack of clearance between the tire and body. Driving on snowy grades or icy roads may require the use of tire chains, in which case put the chains on the front wheels only. Use only SAE class S type chains that are of the correct size for your tires so as not to damage the vehicle body or suspension. When driving with tire chains, drive at speeds below 19 mph (30 km/h). When a temporary spare tire is on a front wheel, replace the temporary spare tire with the rear tire on the same side of the vehicle, and then fit chains on the front tires. Always use the utmost care when driving with tire chains - overconfidence because you are driving with tire chains could easily lead to a serious accident. J Rocking the vehicle If you must rock the vehicle to free it from snow, sand, or mud, depress the accelerator pedal slightly and move the selector lever back and forth between "D" and "R" repeatedly. Do not race the engine. For the best possible traction, avoid spinning the wheels when trying to free the vehicle. When the road surface is extremely slippery, you can obtain better traction by starting the vehicle with the transmission in 2nd than 1st (both for MT and AT). Refer to the Automatic Transmission section in this chapter for information on holding the transmission in 2nd position. - CONTINUED- 7-41
