ADVANCETRAC WITH ROLL STABILITY CONTROL™ (RSC ) STABILITY ENHANCEMENT SYSTEM WARNING: Vehicle modifications involving braking system, aftermarket roof racks, suspension, steering system, tire construction and/or wheel/tire size may change the handling characteristics of the vehicle and may adversely affect the the performance of the AdvanceTrac with RSC system. In addition, installing any stereo loudspeakers may interfere with and adversely affect the AdvanceTrac with RSC system. Install any aftermarket stereo loudspeaker as far as possible from the front center console, the tunnel, and the front seats in order to minimize the risk of interfering with the AdvanceTrac with RSC sensors. Reducing the effectiveness of the AdvanceTrac with RSC system could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. WARNING: Remember that even advanced technology cannot defy the laws of physics. It's always possible to lose control of a vehicle due to inappropriate driver input for the conditions. Aggressive driving on any road condition can cause you to lose control of your vehicle increasing the risk of personal injury or property damage. Activation of the AdvanceTrac with RSC system is an indication that at least some of the tires have exceeded their ability to grip the road; this could reduce the operator's ability to control the vehicle, potentially resulting in a loss of vehicle control, vehicle rollover, personal injury and death. If your AdvanceTrac with RSC system activates, SLOW DOWN. 201 2009 Mariner (mrn) Owners Guide, 2nd Printing USA (fus)
