Driving Note: Pressing the AdvanceTrac௡ with RSC button will disable the AdvanceTrac௡ with RSC system. Aggressive driving in any road conditions can cause you to lose control of your vehicle increasing the risk of severe personal injury or property damage. The occurrence of an AdvanceTrac௡ with Roll Stability Control௢ event is an indication that at least some of the tires have exceeded their ability to grip the road; this may lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. If you experience a severe road event, SLOW DOWN. STEERING Your vehicle is equipped with power steering. Power steering uses energy from the engine to decrease the driver's effort in steering the vehicle. To prevent damage to the power steering pump: • Never hold the steering wheel to the extreme right or the extreme left for more than a few seconds when the engine is running. • Do not operate the vehicle with the power steering pump fluid level below the MIN mark on the reservoir. If the power steering system breaks down (or if the engine is turned off), you can steer the vehicle manually, but it takes more effort. If the steering wanders or pulls, check for: • Underinflated tire(s) on any wheel(s) • Uneven vehicle loading • High crown in center of road • High crosswinds • Wheels out of alignment • Loose or worn suspension components Speed sensitive steering Your vehicle is equipped with speed sensitive, variable assist power steering. At low speeds, steering assist will adjust to reduce efforts and improve low speed maneuverability and at high speeds, the assist will adjust to improve steering feel. If the amount of effort required to steer your vehicle changes while driving at a constant vehicle speed, have the power steering system checked by your authorized dealer. 281 2006 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
