eAssist Features
eAssist Overview
Vehicles with the 2.5L engine have
eAssist, with additional features that
contribute to increased efficiency.
Vehicles with eAssist have an
automatic engine Stop/Start feature.
This feature saves fuel by shutting
the engine off when the vehicle is
stopped. When the engine shuts off
automatically, all the accessories
will continue to operate normally. In
very hot or cold conditions, the
engine may not shut off. See
There are two air conditioning
settings available. The MAX setting
maximizes cabin comfort. The ECO
setting maximizes efficiency
allowing more frequent, and longer
engine stops than the MAX setting.

Dual Automatic Climate Control
Vehicles with eAssist include an
AUTO STOP indicator on the
tachometer. See
