Regenerative Braking; Battery; Service - Chevrolet Impala Owner's Manual

mode. Remember to shift to P (Park)
and turn the ignition to LOCK/OFF
before exiting the vehicle.
See Starting the Engine on
page 9-19.
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.
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.
Vehicles with eAssist also have 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. See
Battery on page 10-27.
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
Doing Your Own Service Work on
page 10-3.
The Traction Control System (TCS)
limits wheel spin. The system turns
on automatically every time the

difficult driving conditions. The
system also turns on automatically
every time the vehicle is started.
To turn off traction control, press
and release the button on the
center console. The Traction Off
Light illuminates.
To turn off both traction control
and StabiliTrak, press and hold
