Maintenance and Specifications Changing rear window wiper blade The rear wiper arm is designed without a service position. This reduces the risk of damage to the blade in an automatic car wash. To replace the wiper blade: 1. Grab the wiper arm with one hand close to the arm/blade joint and pull it as far away from the glass as possible. Do not use excessive force because it can break the wiper arm at the heel. Hold it there until the next step. 2. Grab the primary structure of the blade with the other hand close to the arm/blade joint. 3. Grip tightly and push on the arm/blade joint from beneath and separate the blade from the arm. 4. Attach the new wiper to the wiper arm and press it into place until a click is heard. If you find this procedure too difficult, please see your dealer. ENGINE OIL Checking the engine oil Refer to scheduled maintenance information for the appropriate intervals for checking the engine oil. 1. Make sure the vehicle is on level ground. 2. Turn the engine off and wait 15 minutes for the oil to drain into the oil pan. 3. Set the parking brake and ensure the gearshift is securely latched in P (Park). 4. Open the hood. Protect yourself from engine heat. 5. Locate and carefully remove the engine oil level dipstick. 271 2009 Mariner (mrn) Owners Guide, 2nd Printing USA (fus)
