WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In

Systems/Battery System, Hybrid Drive/Service Precautions
The Multiple Displacement System (MDS) provides cylinder deactivation during steady speed, low acceleration and shallow grade climbing conditions
to increase fuel economy.
CAUTION: Engines equipped with MDS use both standard roller tappets (2) and deactivating roller tappets (1). The deactivating roller
tappets must be used in cylinders 1,4,6,7. The deactivating tappets can be identified by the two holes in the side of the tappet body
(3), for the latching pins.
CAUTION: The tappets and guide holder assembly must be installed as an assembly and in their original locations or engine damage could
result.
1. Lubricate the tappet guide holder (1) and tappets (2).
