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
located behind the rear seat, on the
filler panel. Do not cover the intake.
See Battery on page 10�29.
High Voltage Safety
Information
eAssist vehicles 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.
The negative 12-volt battery cable
and the high voltage cable in the
engine compartment are clearly
labeled. In emergency situations,
first responders can cut those
cables to disable the high voltage
battery system.

Driver Efficiency Gauge
This gauge assists in driving
efficiently and may vary during
normal operation.

See Driver Efficiency Gauge onpage 5�12 for more information.
Automatic Engine
Start/Stop Feature
Vehic les wit h eAssi st h ave 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 r e st a r t t h e e n gi n e dur i ng t h e a u to
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 Ta c h o m e t er onpage 5�11 for more information.

door is opened while in auto stop
mode. Remember to shift to P (Park)
and turn the ignition to LOCK/OFF
before exiting the vehicle.
See Starting the Engine onpage 9�19.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it into electrical energy.
This energy is then stored in the
vehicle's high voltage battery
system, contributing to increased
fuel efficiency.
The system works whenever the
accelerator pedal is released, and
increases the energy captured as
more brake pedal is applied.

Battery
This vehicle has a standard 12�volt
battery. Refer to the replacement
number on the original battery label
when a new standard 12�volt battery
is needed.
eAssist vehicles also have a high
voltage battery. Only a trained
service technician with the proper
knowledge and tools should inspect,

Service
Never try to do your own service on
eAssist components. You can be
injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these high voltage components
should only be performed by a
trained service technician with the
proper knowledge and tools. See
