See Sunroof on page 2‑22.eAssist Features
eAssist®Overview
If the vehicle has eAssist, there are
several additional features which
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 9‑22.
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 8‑5. 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 9‑38.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an efficiency gauge, and
an AUTO STOP indicator on the
tachometer. See Instrument Cluster
on page 5‑10. There is also a Power
Flow Gauge in the Driver
Information Center (DIC). See
Driver Information Center (DIC) on
page 5‑27.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.

Black plate (23,1)Buick LaCrosse Owner Manual - 2012
In Brief 1-23
The cold air intake for the battery is
located behind the rear seat, on the
filler panel. Do not cover the intake.
SeeBattery on page 10‑25.
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 the driver in
operating the vehicle more
efficiently and will vary based on
driver input.
SeeDriver Efficiency Gauge on
page 5‑13 for more information.

1-24 In Brief
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 5‑12 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 on
page 9‑22.
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,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service. See
Battery on page 10‑25.
