Displacement on Demand™ (DoD™)
(5.3L Engine)

Your vehicle’s engine may be equipped with
Displacement on Demand™ (DoD™). This system
allows the engine to operate on either all or half of its
cylinders, depending on your driving conditions.

When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing your vehicle to achieve
better fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.

When greater power demands are required, such as
accelerating from a stop, passing, or merging onto
a freeway, the system will maintain eight-cylinder
operation. When less power is required, such a
cruising at a constant vehicle speed, the system will
automatically enable the four-cylinder mode, allowing
your vehicle to achieve better fuel economy.

Automatic Transaxle Operation

The shift lever for the automatic transaxle is located on
the console between the seats.

Maximum engine speed is limited when the vehicle is in
PARK (P) or NEUTRAL (N) to protect driveline
components from improper operation.

There are several different
positions for the shift lever.
