Lower-aspect-ratio tires and accompanying wheels may provide substantially increased treadwear, increased tire noise and reduced ride comfort. Serious wheel and tire damage may occur if the vehicle is operated on rough or damaged road surfaces or upon encountering road debris or obstacles. These tires are not designed for use on snow and ice. Winter tires mounted on appropriately sized and approved wheels are recommended for driving in those conditions.

Unsecured cargo can become hazardous in a collision. Always secure cargo using the floor-mounted tie-downs.

Camera systems do not audibly notify driver of nearby objects and are not a substitute for actively checking around the vehicle for any obstacles or people. Images displayed may be limited by camera field of view, weather, lighting conditions and the presence of dirt, ice or snow on the camera.

Transparent hood display is composed from vehicle’s exterior cameras, and is available only in specific drive modes at certain speeds. It is not a substitute for actively checking around the vehicle for any obstacles, people or animals in the vehicle’s path or surroundings. Driver is responsible for safely operating vehicle in accordance with terrain, surface and driving conditions. Images displayed may be limited by camera field of view, weather, lighting conditions and the presence of dirt, ice or snow on the camera. See Operator’s Manual for other important information and warnings.

Off-road driving should only be attempted by drivers with the necessary skill, experience and understanding of the vehicle’s limits. Read Operator’s Manual before driving off-road.

Active Distance Assist DISTRONIC® is not a substitute for active driving involvement. It does not adapt cruising speed in response to stationary objects, nor does it predict the curvature and lane layout of the road ahead or the movement of vehicles ahead. It is the driver’s responsibility at all times to be attentive to posted speed limits, traffic and road conditions, and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Drivers are cautioned not to wait for the system’s alerts before braking, as that may not afford sufficient time and distance to brake safely. Braking effectiveness also depends on proper brake maintenance, and tire and road conditions. See Operator’s Manual for system operating speeds and additional information and warnings.

Active Steering Assist requires driver to hold steering wheel and be ready to steer vehicle at any time. It may not recognize lane markings, road features, and/or other vehicles in some lighting, weather and road conditions. It is the driver’s responsibility at all times to be attentive to traffic and road conditions, and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle.

Active Lane Change Assist is not a substitute for active driving involvement. It estimates but does not predict the curvature and lane layout of the road ahead or the movement of vehicles ahead. It is the driver’s responsibility at all times to be attentive to traffic and road conditions, and to provide the driving inputs necessary to retain control of the vehicle. System may not detect some objects, obstacles or vehicles in the area into which the vehicle would move. See Operator’s Manual for system operating speeds and additional information and warnings.

System cannot prevent a collision, and does not alert the driver of an impending collision or system activation. PRESAFE® can initiate closing of the side windows when the system’s sensors detect side movements that suggest a possible rollover or side impact. A small gap is left near the fully closed position.

Audio/multimedia system must be turned on for system to operate.
