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
.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.
The cold air intake for the battery is
under the leading edge of the rear
seat. The exhaust for warm air is in
the trunk. Do not cover the intake or
exhaust. See
.
High Voltage Safety
Information
Vehicles with eAssist have a
standard 12-volt battery and a high
voltage battery. Only a trained
service technician with the proper
knowledge and tools should inspect,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service.
In emergency situations, first
responders can cut the two clearly
labeled cut points in the engine
compartment to disable the high
voltage battery and air bag systems.
Do not cut the high voltage cable.
Automatic Engine Stop/
Start Feature
Vehicles with eAssist have an
automatic engine Stop/Start feature.
After the engine is started and has
reached operating temperature, this
feature may cause Auto Stop which
will turn the engine off when the
brake pedal is applied and the
vehicle comes to a complete stop.
When the brake pedal is released,
or the accelerator pedal is applied,
the engine will restart. The engine
will continue to run until the next
Auto Stop.
AUTO STOP on the tachometer
signifies that the engine is in Auto
Stop mode. See
.
Remember to put the transmission
in P (Park) and turn the ignition off
before exiting the vehicle.
