SeeSunroof 047.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 0178.
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 0157. This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. See
Hill Start Assist
(HSA) 0191.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an AUTO STOP indicator
on the tachometer. See Instrument
Cluster (Base Level Cluster) 0104
or Instrument Cluster (Uplevel
Cluster) 0108.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.

Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9159380) - 2016 - CRC - 2/23/16
22 In Brief
The cold air intake for the battery is
located behind the rear seat, on the
filler panel. Do not cover the intake.
SeeBattery - North America 0241.
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.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See Tachometer0111
for more information. A chime will
sound when the driver 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 0178.
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.
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 - North America 0241.
