SeeSunroof on page 2‑19.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 9‑19.
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 9‑35.
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 5‑9. There is also a Power
Flow Gauge in the Driver
Information Center (DIC). See
Driver Information Center (DIC) on
page 5‑24.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.

1-20 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 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. 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.
Driver Efficiency Gauge
This gauge assists in driving
efficiently and may vary during
normal operation. To maximize efficiency, keep the
gauge pointed in the solid green
zone in the center of the gauge.
See
Driver Efficiency Gauge on
page 5‑12 for more information.
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.

In Brief 1-21
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. SeeTachometer on
page 5‑11 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 9‑19.
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.

alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑10.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure. The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10‑50.Tire Sealant and
Compressor Kit
