Eassist Features - Buick 2015 Regal Owner's Manual

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 on page 9-18.
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 on
page 8-1.
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)
on page 9-34.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an AUTO STOP indicator
on the tachometer. See Instrument
Cluster (Uplevel Cluster) on
page 5-12 or Instrument Cluster
(Base Level Cluster) on page 5-8.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.
In Brief
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 10-26.
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.
