Before starting out on any length of drive – even if it's to go only a couple of miles – make sure your windows are clear of dew, frost, snow, ice, fog, sand, dust, dirt, mud, leaves, and anything else that might obstruct your vision.
Remove accumulated snow from your vehicle's surfaces, including hood and roof. It can blow onto the windshield or cover other windows and block your vision once you're under way. It also can blow onto or in the path of other vehicles, creating a driving hazard!
Have your dealer winterize your Subaru for safer, more economical travel. Your dealer should check:
- The coolant system – to see if it's time to replace and add new antifreeze
- The heater and defroster – for proper operation
- The wiper blades – if necessary, replace with Genuine Subaru Winter Wiper Blades that have a rubber boot covering the arm to prevent snow and ice buildup
- The washer reservoir – fill it and check to see that the system functions properly
- The battery – if it's three years old or older
- The tire pressure and tread depth – to ensure sufficient "grip" on snow and ice
- The brake system – for proper operation
- The exhaust system - to make sure there are no leaks
As air temperatures cool, so does the temperature of the air in your vehicle's tires, contracting the space that it fills. Air pressure drops, underinflating the tires.
Referring to the recommended air pressure in the Owner's Manual or on the label mounted on the driver's door pillar, check tire air pressure for underinflation. Underinflated tires can reduce fuel economy and lead to premature wear of your tires.
If your vehicle is equipped with a tire pressure monitoring system, heed its warnings concerning loss of air pressure.
