{Warning
Do not charge your vehicle’s
battery above an 80%
charge if you are going to
drive down long, steep
grades such as mountain
passes. This provides room
in the battery for
regenerative braking to
supplement your
conventional brakes during
the descent. This is
especially important when
towing a trailer, which puts
additional stress on your
vehicle’s braking system.
See Hill and Mountain Roads
0200 for important
information about driving on
grades.
The default charge level is
100% when plugged in. To set
a different charge level, drag
the circular marker on the
Target Charge Level Gauge to
the preferred value. To lower
the desired Charge Level, drag the Charge Level marker
counterclockwise, and to
increase it drag the marker
clockwise. The Charge Level
can also be changed by
tapping
«andªinside the
gauge on the screen. The
multifunction controller (MCF)
on the center console can also
be used to set the Charge
Level by rotating clockwise or
counterclockwise when the
Target Charge Level Gauge is
highlighted. The Range
estimate updates once the
desired Charge Level is set.
To optimize battery health, the
minimum allowable Charge
Level is determined by the
vehicle. Charge Later
Instead of charging
immediately to a desired
Charge Level, you may choose
to delay the charge to the
vehicle and have it complete
by your desired departure
time. This may be a more
economical choice and a more
efficient use of energy when
charging at home. To use this
mode, touch the Charge Later
tab from the Charging screen.
With Charge Later selected,
the Charging screen displays:
.Text explaining that your
vehicle will delay the planned
charge to be ready by the
time specified.

.Time Selector: Used to set
the desired time at which
the vehicle will finish
charging and be ready for
departure.
.Target Charge Level Gauge:
Sets the percentage at
which the vehicle will stop
charging. The gauge also
displays an estimate of the
vehicle's range upon
completing the charging
session.
.Cabin Pre-Conditioning:

session. Cabin
pre-conditioning happens at
the end of the charge, and
right before the
departure time.To set the time at which the
vehicle will complete the
charge and be ready for
departure:
Swipe up or down on each
value within the Time Selector
until the preferred time is
selected. The time selector
can also be modified using the
