CHARGING YOUR VEHICLE
HINTS
We recommend limiting the amount of DC
charges, and ending DC charges at 80%
state of charge as charging between 80
and 100% can incur high charging costs
due to the time to completion. Frequent
use of DC charging could result in reducing
your battery ’s efficiency and lifespan. This
is more pronounced on the standard range
battery pack versus the extended range
battery pack. In cold temperatures, you may notice that
DC charging takes longer when the
ambient temperature drops below 50°F
(10°C). Shutting off climate control or
reducing climate control temperature and
fan settings for the first 10 to 15 minutes of
DC charging will allow the battery to warm
up and improve the charging rate.
Note: When the temperature is below
freezing, fully turning off cabin heat for the
first 10 to 15 minutes of DC charging could
significantly improve the charging rate.

FREQUENTLY ASKED QUESTIONS
Why does my vehicle not charge with
the mobile charger?
Ensure you properly connect the
connector and control box. Unplug the
charge coupler from the vehicle and
unplug the connector from the wall
outlet. Then check the connector to
be sure that the connector is
connected properly into the mobile
charger control box. If the mobile
charger is warm or in a hot
environment, try charging in a cooler
area. Try a different outlet or a
different connector if you have one
available. If the problem persists,
contact an authorized EV certified
dealer.
Why does my vehicle have a hum or fan
noise when charging? A hum or a fan noise could be present
when charging the high voltage
battery. This is a normal operation as
your vehicle is keeping the battery cool
while charging.

LOW (L)
You can activate this position at any
vehicle speed which provides an increased
level of deceleration when you lift off the
accelerator pedal. You can use low (L) at
all times, if desired, but improving
drivability while descending grades is the
intent. Entering low (L) does not take any
actions if one pedal drive is active.
SHIFTING YOUR VEHICLE INTO
GEAR
Your vehicle has an electronic transmission
selector. The transmission selector is on
the center console. The gears are selected
by rotating the transmission selector to
PRNDL.
• Park (P)
• Reverse (R)
• Neutral (N)
• Drive (D)
• Low (L)
Putting your vehicle in gear:
1. Fully press down the brake pedal.
2. Rotate the gear selector knob to the desired gear mode you want to select.
3. The gear selector will indicate the position selected. 4. Release the brake pedal and your
transmission remains in the selected
gear.
Note: Your gear selector knob can rotate
clockwise past drive (D), but the gear
selection will stay in Drive (D). Your gear
selector can rotate counter-clockwise past
park (P) with the brake pressed, but the gear
selector will stay in park (P).
Note: If you attempt to leave your vehicle
when it is in gear, your vehicle automatically
shifts into park (P).
See How Does
Automatic Return to Park (P) Work (page
185
).
TEMPORARY NEUTRAL MODE
WHAT IS TEMPORARY NEUTRAL
MODE
This mode keeps your vehicle in neutral
(N) when you switch your vehicle off. Use
this mode if you exit your vehicle or switch
your vehicle off at an automatic car wash.
Note: Do not tow your vehicle in this mode.
Note: Automatic return to park (P) is
delayed when your vehicle is in this mode.
See
What Is Automatic Return to Park
(P) (page 185).
TEMPORARY NEUTRAL MODE
LIMITATIONS
Your vehicle could shift to park (P) after
30 minutes, or when the vehicle battery
charge level is low. Prolonged use of this
mode can cause the vehicle battery to run
out of charge.
Do not tow your vehicle in this mode.
Failure to follow these instructions could
result in vehicle damage not covered by
the vehicle warranty.

ELECTRIC POWER STEERING
ELECTRIC POWER STEERING
PRECAUTIONS
WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the vehicle off. After at least 10
seconds, switch the vehicle on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle
manually nor will it cause damage to the
system. Normal steering and driving allows
the system to cool down and steering
assist returns to normal. Note:
There is no fluid reservoir to check or
fill.
ELECTRIC POWER STEERING
ADAPTIVE STEERING
Adaptive Learning
(If Equipped)
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the
brake system to help operate advanced
stability control and crash avoidance
systems.
Note: When the battery is disconnected or
a new battery is installed, you must drive
your vehicle a short distance before the
system relearns the strategy and reactivates
all systems.
Steering Tips
If the steering wanders or pulls, check for:
• An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds could also make the steering
wander or pull.

WHAT IS DRIVE MODE
CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings, for example steering,
instrument cluster graphics, ambient
lighting, interior sound, handling and
powertrain response.
SELECTING A DRIVE MODE
1. Access the vehicle drawer on the
touchscreen.
2. Press CONTROLS.
3. Press
Drive Modes.
4. Press
Engage, Unbridled or Whisper.
Note: Drive mode changes may not be
available when your vehicle is off.
DRIVE MODES
ENGAGE - GT, VEHICLES WITH:
ACTIVE DAMPERS
For everyday driving. This mode is the
perfect balance of excitement, comfort
and convenience. Steering and active
damping are tuned for normal driving. The
interior lights and cluster graphics are set
to soft blue and the battery state of charge
gauge displays.
ENGAGE - VEHICLES WITHOUT:
ACTIVE DAMPERS
For everyday driving. This mode is the
perfect balance of excitement, comfort
and convenience. The interior lights and
cluster graphics are set to soft blue and
the battery state of charge gauge displays. UNBRIDLED - GT, VEHICLES WITH:
ACTIVE DAMPERS
Unbridled mode is for sporty driving with
improved performance handling and
response. This mode increases
acceleration response and provides a
strong deceleration rate when you lift off
the accelerator pedal. Unbridled mode
makes your vehicle accelerate faster and
provides sportier steering feel. Steering and
active damping are tuned for performance.
The interior sound increases and the
ambient lights and cluster graphics are set
to orange with a graphic related to your
acceleration and steering inputs.
Unbridled Extend
This feature adjusts unbridled mode to
provide high-performance driving and is
for track and closed course use only. When
activated, this mode provides balanced
power output for lap time consistency. The
accelerator pedal is calibrated for
improved propulsion control. The system
provides more performance orientated
traction and stability control. In this mode,
traction and stability control intervention
is reduced and tuned specifically for track
usage only. The interior sound increases
and the ambient lights and cluster graphics
are set to orange with a graphic related to
your acceleration and steering inputs.
To use this feature, you must be in
unbridled mode with the unbridled extend
slider selected with the battery at
operating temperature. When using this
mode, one pedal drive is not available and
other driver assistance features are
disabled.
Note:
This feature may not be available in
temperatures below
32°F (0°C), or 59°F
(15°C) for the battery.
Note: If the feature is not available, charge
your vehicle until the battery has sufficient
charge, and temperature conditions are met.
