Ford's Mercury Mountaineer is a Sports Utility Vehicle, or SUV. This type of vehicle handles differently than a passenger automobile, and is not designed for cornering at high speed or making sharp turns. Tires, wheels and loading are three of the most critical and fundamental elements that affect a Mercury Mountaineer's ride. The latest Mountaineers are also fitted with an enhanced stability system Ford calls Advancetrac with Roll Stability Control, or RSC. Improving the ride on a Mountaineer can be achieved by tweaking these elements.
Check the tire pressure with a pressure gauge if the vehicle is riding poorly. Some newer models have a tire inflation warning light in the instrument cluster that can alert you to problems. Inflate the tires to the recommended pressure as indicated on the tire and also printed on the label attached to the inside edge of the front door. Look for wear and replace the tire if tread is worn below 1/16-inch.2
Monitor the SUV for pulling to one side when driving. This can indicate that the wheels are out of alignment. This is often caused by hitting hitting pot holes and curbs. Have the alignment corrected by a repair shop.3
Drive at safe speeds for the conditions, which in this type of vehicle are slower with less abrupt movements than a sedan. Avoid sharp turns. Load the SUV to within the payload parameters specified on the same label mentioned in Step 1. The payload is the combined weight of passengers and cargo.4
Switch the RSC system on if it's off. RSC is enabled by default on start-up, but can be disabled by pressing the RSC button momentarily. Sometimes, you may turn RSC off if you're maneuvering in snow, mud or sand. Doing this provides with more power and forward momentum. Turn it back on again when you have reached a solid footing.
