eAssist Features
eAssist®Overview
If the vehicle has eAssist, there are
several additional features that
contribute to increased efficiency.
Vehicles with eAssist have an
automatic engine start/stop 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 will only shut off
automatically part of the time. See
Starting the Engine on page 9-19.
There are two air conditioning
settings available. The comfort
setting maximizes cabin comfort.
The eco setting maximizes
efficiency allowing more frequent,
and longer engine stops than the
comfort setting. See Dual Automatic
Climate Control System on
page 8-3.

Economy (If Equipped)
The climate control system is
dependent upon other vehicle

Certain climate control settings can
lead to higher fuel usage and/or
fewer auto stops.
The following are climate control
settings that use more fuel:
.Comfort air conditioning mode.
.Defrost mode.
.Extreme temperature settings,
such as 15°C (60°F) or 32°C
(90°F).
.High fan speed settings.
To help reduce fuel usage:
.Use the full automatic control as
described under “Automatic
Operation.”
.Use eco air conditioning, instead
of the comfort air conditioning.
