the vehicle is plugged into a charging
station, the Portable Cord Limit option on
the Charge Mode tab will not be available.
The Portable Cord Limit can be changed and
saved using Location Based Charging
settings. The default value is the lower
Portable Cord Limit. The Portable Cord Limit
will reset to the lower value when the
vehicle is shifted from P (Park) unless the
Location Based Charging feature is active
and set to retain this preference. See
“Location Based Charging” later in this
section.
{Warning
Using a charge level that exceeds the
electrical circuit or electrical outlet
capacity may start a fire or damage the
electrical circuit. Use the lowest charge
level until a qualified electrician inspects
the electrical circuit capacity. Use the
lowest charge level if the electrical circuit
or electrical outlet capacity is not known.
Electric Rate Preference
The vehicle estimates the charging start
time based on the utility rate schedule,
utility rate preference, and programmed
departure time for the current day of the
week. The vehicle will charge during the
least expensive rate periods to achieve a full
battery charge by the departure time.
Electrical rate information from the utility
company for the charging location is
required for this mode. If the selected
charge mode is Departure, then electric rate
preference selection will display. Electric Rate Preference Selection
From the Charge Mode tab on the Charging
screen with Departure charge mode selected,
touch More to select the Electric Rate
Preference.
Touch one of the following options to select
the Electric Rate Preference:
.Off: Delay charging based on departure.
.Off-Peak Only: Charge during Off-Peak
Rates.
.Cost Optimized Off- and Mid-Peak: Charge
during Mid-Peak and Off-Peak Rates.
.Cost Optimized All Rates: Charge during
Peak, Mid-Peak, and Off-Peak Rates.
Charging begins at the start time and is
complete by the departure time only if
sufficient time is allowed after the charge
cord is plugged in. For example, if the
vehicle is plugged in for only one hour prior

additional security.
FCC Information
SeeRadio Frequency Statement 0271.
Utility Interruption of Charging
This vehicle will respond to requests through
the utility company to limit or completely
block electrical power grid usage. This
feature is inactive during DC charging.
A utility interruption of charging will
lengthen the vehicle charge time.
When electrical grid power is completely
blocked, the vehicle will delay charging until
the utility interruption has expired. The
vehicle should be left plugged in so that the
vehicle can automatically begin charging. Changing the charge mode to Immediate or
performing a delayed charging override will
not disable a utility interruption. Unplugging
and plugging the car back in will also not
disable a utility interruption.
A pop-up will appear in the infotainment
display while starting the vehicle following
any utility interruption. See
“Charging
Interrupted or Overridden Pop-Up” under
Programmable Charging 090.
A message will display on the instrument
cluster indicating that a utility interruption
has occurred.

Traction:The friction between the tire
and the road surface. The amount of
grip provided.
Tread
:The portion of a tire that comes
into contact with the road.
Treadwear Indicators
:Narrow bands,
sometimes called wear bars, that show
across the tread of a tire when only
1.6 mm (1/16 in) of tread remains. See
When It Is Time for New Tires 0227.
UTQGS (Uniform Tire Quality Grading
Standards)
:A tire information system
that provides consumers with ratings
for a tire's traction, temperature, and
treadwear. Ratings are determined by
tire manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire.
See Uniform Tire Quality Grading 0229.
Vehicle Capacity Weight
:The number
of designated seating positions
multiplied by 68 kg (150 lb) plus the
rated cargo load. See Vehicle Load
Limits 0153. Vehicle Maximum Load on the Tire
:
Load on an individual tire due to curb
weight, accessory weight, occupant
weight, and cargo weight.
Vehicle Placard
:A label permanently
attached to a vehicle showing the
vehicle capacity weight and the original
equipment tire size and recommended
inflation pressure. See “Tire and Loading
Information Label” underVehicle Load
Limits 0153.
Tire Pressure
Tires need the correct amount of air
pressure to operate effectively.
{Warning
Neither tire underinflation nor
overinflation is good. Underinflated
tires, or tires that do not have
enough air, can result in:
.Tire overloading and overheating
which could lead to a blowout.
.Premature or irregular wear.
.Poor handling.
