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 orInstrument 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.
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.

7576024) - 2015 - CRC - 9/15/14
1-20 In Brief
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.
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 5-15 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 9-18.
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 on page 10-26.
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
Doing Your Own Service Work on
page 10-3.

needed.
If locked out of the vehicle, see
Roadside Assistance Program on
page 13-5.With an active OnStar subscription,
an OnStar Advisor may remotely
unlock the vehicle. See
OnStar
Overview on page 14-1.
Remote Keyless Entry
(RKE) System
See Radio Frequency Statement on
page 13-12.
If there is a decrease in the RKE
operating range:
.Check the distance. The
transmitter may be too far from
the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the transmitter's battery.
See “Battery Replacement” later
in this section.
.If the transmitter is still not
working correctly, see your
dealer or a qualified technician
for service.

Remote Vehicle Start
If equipped, this feature that allows
the engine to be started from
outside the vehicle.
/(Remote Vehicle Start): This
button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear defog may
come on during remote start based
on cold ambient conditions. The
rear fog indicator light does not
come on during remote start. If the
vehicle has heated seats, they may
come on during a remote start. See
Heated Front Seats on page 3-8. Laws in some local communities
may restrict the use of remote
starters. For example, some laws
require a person using remote start
to have the vehicle in view. Check
local regulations for any
requirements.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System on page 2-2.
Starting the Vehicle
To start the engine using the remote
start feature:
1. Press and release
Q.
2. Immediately press and hold
/

2-18 Keys, Doors, and Windows
The immobilization system is
disarmed when the ignition button is
pushed in and a valid transmitter is
found in the vehicle.
The security light on the instrument
cluster comes on when there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.If the vehicle does not start and the
security light stays on, there is a
problem with the system. Turn the
vehicle off and try again.
If the RKE transmitter appears to be
undamaged, try another transmitter,
or place the transmitter in the
transmitter pocket. See
“Starting the
Vehicle with a Low Transmitter
Battery” underRemote Keyless
Entry (RKE) System Operation on
page 2-3.
If the vehicle does not start with the
other transmitter or when the
transmitter is in the transmitter
pocket, your vehicle needs service.
See your dealer who can service
the theft-deterrent system and have
a new transmitter programmed to
the vehicle.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
