Wash the vehicle regularly to prevent corrosion of the body and suspension components. Also, wash the vehicle promptly after driving on any of the following surfaces.
After the winter has ended, it is recommended that the underbody be given a very thorough washing.
Before the beginning of winter, check the condition of underbody components, such as the exhaust system, fuel and brake lines, brake cables, suspension, steering system, floor pan, and fenders. If any of them are found to be rusted, they should be given an appropriate rust prevention treatment or should be replaced. Contact your SUBARU dealer to perform this kind of maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt accumulation under the floor mats because that could cause corrosion.
Occasionally check under the mats to make sure the area is dry.
Keep your garage dry. Do not park your vehicle in a damp, poorly ventilated garage. In such a garage, corrosion can be caused by dampness. If you wash the vehicle in the garage or put the vehicle into the garage when wet or covered with snow, that can cause dampness.
If your vehicle is operated in cold weather and/or in areas where road salts and other corrosive materials are used, the door hinges and locks, and hood latch should be inspected and lubricated periodically.
