8-8 Driving tips 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 afterwards thoroughly wipe the water away. Use a windshield washer fluid that contains an antifreeze solution. Do not use engine antifreeze or other substitutes because they may damage the paint of the vehicle. SUBARU Windshield Washer Fluid contains 58.5% methyl alcohol and 41.5% surfactant, by volume. Its freezing temperature varies according to how much it is diluted, as indicated in the following table. Washer Fluid Concentration 30% 50% 100% Freezing Temperature 10.48F (−128C) −48F (−208C) −498F (−458C) 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. winter driving, stop when and where it is safe to do so and check under the fenders periodically. ! Parking in cold weather WARNING Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the exhaust pipe and from around your vehicle if you park the vehicle in snow with the engine running. Do not use the parking brake when parking for long periods in cold weather since it could freeze in that position. Instead, observe the following. 1. Place the selector lever in "P" position. 2. Use tire stops under the tires to prevent the vehicle from moving. When the vehicle is parked in snow or when it snows, raise the wiper blades off the glass to prevent damage to them. When the vehicle has been left parked after use on roads heavily covered with snow, or has been left parked during a snowstorm, icing may develop on the brake system, which could cause poor braking action. Check for snow or ice buildup on the suspension, disc brakes CAUTION Adjust the washer fluid concentration appropriately for the outside temperature. If the concentration is inappropriate, sprayed washer fluid may freeze on the windshield and obstruct your view, and the fluid may freeze in the reservoir tank. ! Before driving your vehicle Before entering the vehicle, remove any snow or ice from your shoes because that could make the pedals slippery and dangerous. While warming up the vehicle before driving, check that the accelerator pedal, brake pedal, and all other controls operate smoothly. Clear away ice and snow that has accumulated under the fenders to avoid making steering difficult. During severe 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
