The engine may run when Mountain
Mode is selected, depending on the
high voltage battery charge, to build
reserve battery charge for uphill
climbs. If Mountain Mode is entered
with a sufficient battery charge
reserve, the battery charge reserve
will appear grayed out and any
battery charge reserve still unused
upon exiting Mountain Mode will
return to normal appearance.
Press Drive Mode again to return to
Normal Mode and it becomes active
after three seconds.
Each time the vehicle is started, it
will return to Normal Mode to
maintain a smaller battery charge
reserve for normal driving.Hold Mode
Use Hold Mode on a trip where it is
expected that all of the electric
charge will be depleted. Use Hold
Mode mainly during highway or high
speed driving to maximize both EV
miles and fuel efficiency.
Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting this
mode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Hold Mode will not change normal
vehicle acceleration or braking
performance.
Press MODE to select Hold Mode.
Press MODE again to return to
Normal Mode and it becomes active
after three seconds.
Each time the vehicle is started, it
will return to Normal Mode.
Out of Fuel/Engine
Unavailable
If the vehicle runs out of fuel, or the
engine will not start due to a
malfunction, the vehicle can
continue to be driven in Electric
Mode until the current charge is
depleted. The vehicle will have less
responsive acceleration. DIC
messages indicate reduced

stationary. If HSA is holding the
vehicle, a DIC message displays.
HSA will not activate in a forward
drive gear when facing downhill,
or in R (Reverse) when facing uphill.
Extended Hill Start
Assist (EHSA)
Select the duration of the HSA
feature on the center stack
touchscreen by choosing the
submenu for Hill Start Assist or
Extended Hill Start Assist (EHSA).
See“Extended Hill Start Assist"
under “Comfort and Convenience” in
Vehicle Personalization 0138.
When Standard Hold is selected,
the vehicle is held stationary for up
to two seconds after the brake pedal
is released. When Extended Hold is
selected, the vehicle is held
stationary for up to five minutes
after the brake pedal is released. In
either case, override the hold
feature by pressing the accelerator
pedal and attempting to drive away.
If Hill Start Assist is selected in the
Settings menu, it will hold the
vehicle for two seconds unless the
driver door is opened or the driver safety belt is unbuckled after
releasing the brake pedal.
If Extended Hill Start Assist is
selected, it will hold the vehicle for
five minutes unless the driver door
is opened and the driver safety belt
is unbuckled prior to releasing the
brake pedal. When EHSA is
deactivated after five minutes, or if it
is deactivated when the driver
safety belt is unlatched or the driver
door is opened, the Electric Parking
Brake will engage to prevent vehicle
movement.
Regenerative Braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is
then stored back into the high
voltage battery system, increasing
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The controller interprets the braking
request and uses regenerative
braking, conventional hydraulic
braking, or a combination of both as
necessary.
The brake controller applies the
hydraulic brakes using a pump. The
pump may be heard during some
braking, such as rapid applies. This
is normal.
See
Warning Lights, Gauges, and
Indicators 0100 andDriver
Information Center (DIC) 0128.
If there is a controller problem, the
brake pedal may be harder to push
and the stopping distance may be
longer.

When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LKA assistance and/or LDW alerts
may occur due to tar marks,
shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LKA off if these
conditions continue.
Charging
Plug-In Charging
This section explains the charging
of the vehicle's high voltage battery.
Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
plugged in. Plug the vehicle in when
temperatures are below 0 °C (32 °F)
and above 32 °C (90 °F) to
maximize the life of the high voltage
battery.
When using a 120-volt AC electrical
outlet, it will take approximately
13 hours to charge the vehicle with
the 12 amp AC current setting or
19 hours using the default 8 amp
AC current setting. When using a
240-volt charging station, it will take
approximately 4.5 hours to charge
the vehicle. Charge times will vary
with outside temperature. There are
three ways to program how the
vehicle is charged. See
Programmable Charging 0118.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned off. Additional unexpected clicking
sounds may be caused by the
electrical devices used while
charging.
While the charge cord is plugged
into the vehicle, the vehicle cannot
be driven.

Charging Status
Feedback
The vehicle has a Charging Status
Indicator (CSI) at the center of the
instrument panel near the
windshield. When the vehicle is
plugged in and the vehicle power is
off, the CSI indicates the following:
. Short Flashing Green –Vehicle
is plugged in. Battery is not fully
charged. Flash rate increases
from one to four flashes as
battery charges.
. Long Flashing Green –Vehicle
is plugged in. Battery is not fully
charged. Battery charging is
delayed.
. Solid Green –Vehicle is plugged
in. Battery is fully charged.
. Solid Yellow –Vehicle is plugged
in. It is normal for the CSI to turn
yellow for a few seconds after
plugging in a compatible charge
cord. The solid yellow may be
extended depending on the
vehicle and if there is a total
utility interruption via OnStar. See
Utility Interruption of
Charging 0218. This may also
indicate that the charging
system has detected a fault and
will not charge the battery. See
“Charge Cord Status Indicators”
in Charge Cord 0210.
If the vehicle is plugged in and
vehicle power is on, the CSI will
flash or will be solid green,
depending on the charge level. This
also happens during a remote start
if the vehicle is plugged in.
If the vehicle is plugged in and the
CSI is off, a total utility interruption
using OnStar or a charging fault has
been detected. See Utility
Interruption of Charging 0218 or
“Charge Cord Status Indicators” in
Charge Cord 0210.
Following is the vehicle feedback
when the charge cord is plugged in.
