Driving • If the vehicle goes from one type of surface to another (i.e., from concrete to gravel) there will be a change in the way the vehicle responds to a maneuver (steering, acceleration or braking). Again, avoid these abrupt inputs. AWD Systems (if equipped) AWD uses all four wheels to power the vehicle. This increases traction, enabling you to drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot. Sand When driving over sand, try to keep all four wheels on the most solid area of the trail. Avoid reducing the tire pressures but shift to a lower gear and drive steadily through the terrain. Apply the accelerator slowly and avoid spinning the wheels. If you must reduce the tire pressure for whatever reason in sand, make sure you re-inflate the tires as soon as possible. Note: If your vehicle is equipped with the tire pressure monitoring system, the system indicator light may illuminate depending on how much air is released from your tires and/or how long you drive the vehicle under these conditions. Avoid excessive speed because vehicle momentum can work against you and cause the vehicle to become stuck to the point that assistance may be required from another vehicle. Remember, you may be able to back out the way you came if you proceed with caution. Mud and water If you must drive through high water, drive slowly. Traction or brake capability may be limited. When driving through water, determine the depth; avoid water higher than the bottom of the hubs (if possible) and proceed slowly. If the ignition system gets wet, the vehicle may stall. 156 2004 Mountaineer (mnt) Owners Guide (post-2002-fmt) USA English (fus)
