• When the vehicle is parked in an area
exposed to direct sunlight, Ensure the
remote controller is placed in an area not
exposed to direct sunlight. For example:
Glove box.
Under direct sunlight, signal reception
from the remote controller weakens. If
this happens, hold the remote controller
close to the signal receptor on the front
panel.
