8-8 Driving tips/Winter driving – When the vehicle has been left parked during a snowstorm Check for snow or ice buildup on the suspension, disc brakes and brake hoses underneath the ve- hicle. If there is caked snow or ice, remove it, being careful not to damage the disc brakes and brake hoses and ABS harness. When parking for long periods in cold weather, you should observe the following tips. 1. For MT models, place the shift lever in the “1” or “R” position. For CVT models, place the select lever in the “P” position. 2. Use tire stops under the tires to prevent the vehicle from moving. ! Refueling in cold weather To help prevent moisture from forming in the fuel system and the risk of its freezing, use of an antifreeze additive in the fuel tank is recommended during cold weather. Use only additives that are specifically designed for this purpose. When an antifreeze additive is used, its effect lasts longer if the tank is refilled whenever the fuel level reaches half empty. If your SUBARU is not going to be used for an extended period, it is best to have the fuel tank filled to capacity. & Driving on snowy and icy roads To prevent skidding and slipping, avoid sudden braking, abrupt acceleration, high- speed driving, and sharp turning when driving on snowy or icy roads. Always maintain ample distance between your vehicle and the vehicle ahead of you to avoid the need for sudden braking. To supplement the foot brake, use the engine brake effectively to control the vehicle speed. (Shift into a lower gear when necessary.) Avoid shifting down abruptly. Such beha- vior can cause the wheels to lock, possibly leading to loss of vehicle control. An anti-lock brake system (ABS) en- hances your vehicle’s braking perfor- mance on snowy and icy roads. For information on braking on slippery sur- faces, refer to “ABS (Anti-lock Brake System)” F7-35 and “Vehicle Dynamics Control system” F7-37. WARNING Do not use the cruise control on slippery roads such as snowy or icy roads. This may cause loss of vehicle control. CAUTION Avoid prolonged continuous driving in snowstorms. Snow will enter the engine’s intake system and may hinder the airflow, which could re- sult in engine shutdown or even breakdown. ! Wiper operation when snowing Before driving in cold weather, make sure the wiper blade rubbers are not frozen to the windshield. If the wiper blade rubbers are frozen to the windshield, use the defroster and the temperature set for maximum warmth until the wiper blade rubbers are completely thawed. Refer to “Climate control” F4-1. If your vehicle is equipped with a wiper deicer, use it. It is helpful to thaw the windshield wiper blade rubbers. Refer to “Defogger and deicer” F3-84. When driving in snow, if frozen snow starts
