Selectable Extended Rear Ride
Height
If the vehicle has this feature it comes as part of the
electronically controlled air suspension system.
The selectable rear ride height allows the rear of the
vehicle to be raised about 2 inches (5 cm) over the
normal ride height. This can be helpful when driving
off-road where more ground clearance may be needed
to clear an obstacle.
The button that controls
this feature is located on
the instrument panel to the
right of the steering wheel.
