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.

The vehicle may have this feature
that allows you to start the engine
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 3‑6.
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.
