Summary
While driving on gravel or dusty roads, dust accumulates at the lower inner edge of the door garnish. When the rear door is opened, the dust may be blown up and enter the cabin, adhering to the seats and the floor. This is caused by a large gap at the lower part of the boundary between the rear door and the front door, and air containing dust and/or sand is sucked up into the gap, accumulating at the lower edge of the rear door garnish while driving. To eliminate this concern, a mass production change is under study.

DESCRIPTION
While driving on gravel or dusty roads, dust accumulates at the lower inner edge of the door garnish. When the rear door
is opened, the dust may be blown up and enter the cabin, adhering to the seats and the floor. This is caused by a large
gap at the lower part of the boundary between the rear door and the front door, and air containing dust and/or sand is
sucked up into the gap, accumulating at the lower edge of the rear door garnish while driving. To eliminate this concern,
a mass production change is under study.
Customers having this concern should have their vehicle repaired using the following repair procedure.
NOTE: This repair procedure is an interim countermeasure. After a mass production change is implemented, the repair
procedure will be updated.
