Active Fuel Management
This vehicle's engine may be equipped
with Active Fuel Management, which
allows the engine to operate on either
all of its cylinders, or in reduced
cylinder operation mode, depending
on the driving conditions. When less
power is required, such as cruising at
a constant vehicle speed, the system
will operate in reduced cylinder operation mode, allowing the 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. If the vehicle has an Active
Fuel Management indicator, see Driver
Information Center (DIC) for more
information on using this display.
