In Brief
eAssist vehicles have a Hill Start
Assist (HSA) feature, which may be
useful when the vehicle is stopped
on a grade. See
Hill Start Assist
(HSA) on page 9-33
.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an AUTO STOP indicator
on the tachometer. See
Instrument
Cluster on page 5-9
.
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
behind the rear seat, on the filler
panel. Do not cover the intake. See
Battery on page 10-27
.
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 Start/
Stop Feature
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn 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.
To restart the engine during the auto
stop, release the brake pedal or
press the accelerator pedal. The
engine starts immediately. The
vehicle continues to run until the
next stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See
Tachometer on
page 5-13
for more information.
A chime will sound when the driver
door is opened while in auto stop
