35 mph (56 km/h), the fold feature will be disabled,
however the mirrors will attempt to unfold at any speed.

between the power mirror switches L (left) and R (right).
Press the switch once and the mirrors will fold in,
pressing the switch a second time will return the mirrors
to the normal driving position.
NOTE: Ten or more switch activations within one
minute will disable the fold/unfold feature to protect the
