STANDARD PROCEDURE - LIFTGATE
ADJUSTMENT
In order for the power liftgate system to function
properly the liftgate must move freely and smoothly.
The power liftgate system can acommodate for some
minor changes in the effort required to move the lift-
gate. However, in extreme conditions the liftgate may
need to be mechanicaly adjusted for proper fit and
finish. Refer to the Liftgate Adjustment procedure in
the Body section of the service manual for detailed
instructions.
