8-8 Driving tips/Winter driving 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 CVT). For CVT models, refer to “Selection of manual mode” F7-28. ! After driving . Always check your brakes for effec- tiveness immediately after driving in sand, mud or water. Do this by driving slowly and stepping on the brake pedal. Repeat that process several times to dry out the brake discs and brake pads. . After driving through tall grass, mud, rocks, sand, rivers, etc., check that there is no grass, bush, paper, rags, stones, sand, etc. adhering to or trapped on the underbody. Clear off any such matter from the underbody. If the vehicle is used with these materials trapped or adhering to the underbody, a mechanical breakdown or fire could occur. . Wash the vehicle’s underbody after off- road driving. Suspension components are particularly prone to dirt buildup, so they need to be washed thoroughly. Winter driving & Operation during cold weather Carry some emergency equipment, such as a window scraper, a bag of sand, flares, a small shovel and jumper cables. Check the battery and cables. Cold temperatures reduce battery capacity. The battery must be in good condition to provide enough power for cold winter starts. It normally takes longer to start the engine in very cold weather conditions. Use an engine oil of a proper grade and viscosity for cold weather. Using heavy summer oil will make it harder to start the engine. Keep the door locks from freezing by squirting them with deicer or glycerin. Forcing a frozen door open may damage or separate the rubber weather strips around the door. If the door is frozen, use hot water to melt the ice, and after- wards thoroughly wipe the water away. Use a windshield washer fluid that con- tains an antifreeze solution. Do not use engine antifreeze or other substitutes because they may damage the paint of the vehicle. SUBARU Windshield Washer Fluid con- tains 58.5% methyl alcohol and 41.5% surfactant, by volume. Its freezing tem- perature varies according to how much it is diluted, as indicated in the following table. Washer Fluid Con centration Freezing Temperature 30% 10.48F (−128C) 50% −48F (−208C) 100% −498F (−458C) In order to prevent freezing of washer fluid, check the freezing temperatures in the table above when adjusting the fluid concentration to the outside temperature. If you fill the reservoir tank with a fluid with a different concentration from the one used previously, purge the old fluid from the piping between the reservoir tank and washer nozzles by operating the washer for a certain period of time. Otherwise, if the concentration of the fluid remaining in the piping is too low for the outside temperature, it may freeze and block the nozzles. CAUTION . Adjust the washer fluid concen- tration appropriately for the out-
