rate, ensure the
smartphone is fully seated
and centered in the holder
with nothing under it.
A thick smartphone case
may prevent the charger
from working, or reduce the
charging performance. See
your dealer for additional
information.
4. A green

the infotainment display,
next to the phone icon. This
indicates that the
smartphone is detected.
5. If a smartphone is placed on the charger and
]turns off
or a yellow triangle appears,
remove the smartphone and
any objects from the pocket.
Turn the smartphone
180 degrees and wait a few
seconds before placing/
aligning it on the pocket
again.
6. If a smartphone is placed on the charger and a red circle

Battery Load
Management
The vehicle has Electric Power
Management (EPM) that
estimates the battery
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the 12–
volt battery
When the battery state of
charge is low, the voltage is
raised slightly to quickly
increase the charge. When thestate of charge is high, the
voltage is lowered slightly to
prevent over charging. As this
adjustment occurs, you may
see the voltage move up or
down on the voltmeter gauge
or voltage display on the
Driver Information (DIC),
if equipped. This is normal. If a
problem occurs, an alert will be
displayed.
If the electrical loads are very
high, the battery can be
discharged when the vehicle is
stationary. A high electrical
load occurs when several
features are on, such as:
headlamps, high beams, rear
window defogger, climate
control fan at high speed,
heated seats, motor cooling
fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent
excessive discharge of the
battery by balancing the
electrical system output and
the vehicle's electrical needs.

194 Driving and Operating
Acceleration/Braking/
Coasting
Avoid rapid accelerations and
decelerations.
Use cruise control when
appropriate.
Plan ahead for decelerations,
and coast whenever possible.
Do not rush to traffic signals,
and do not shift to N (Neutral)
to coast.
Use the One-Pedal Driving
feature when appropriate to
help recover energy during
coasting and braking.
One-Pedal mode recovers
more energy while coasting
and braking than D (Drive)
mode. See One-Pedal Driving
0214.
Use the steering wheel Regen
on Demand paddle during
deceleration to help recover
energy. See Regenerative
Braking 0220. Terrain and Vehicle Speed
Higher speeds and grade
changes use more energy and
can significantly reduce
electric range.
Climate Setting
Using the heat and air
conditioning systems
decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved when the heat, air
conditioning, and fan are
turned off.
Use the heated and ventilated
seat features (if equipped)
instead of the climate control
system. Heating and
ventilating the seat uses less
energy than heating and
cooling the interior. See
Heated and Ventilated Front
Seats
045 and
Heated Rear Seats 049.
Use the Remote Start Climate
Control feature to heat or cool
the interior while the vehicle is
plugged in to use electricity from the electrical outlet
instead of using energy from
the battery. See Remote Start
0
15.
In hot weather, avoid parking
in direct sunlight. Use
sunshades inside the vehicle.
Keep the inside of the
windows clean to reduce
fogging. Turn off the front
defroster and rear defogger
when they are not needed.
Avoid driving with the
windows open at highway
speeds.
Use the Battery Gauge on the
Instrument Cluster to view the
effect of climate control
settings on your estimated
range. See Battery Gauge
(High Voltage) 0110.
Outside Temperature
On colder days, it is best to
plug in the vehicle overnight,
and then remote start the
vehicle.

200 Driving and Operating
.Turn off cruise control.
Hill and Mountain
Roads
{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.
If the battery becomes full,
regenerative braking will be
limited or unavailable. The
brakes will have to do all the
work of slowing down the
vehicle and could become(Continued)
Warning (Continued)
too hot. Hot brakes may not
be able to slow the vehicle
enough to maintain speed
and control. To help avoid
the risk of a crash, limit the
battery’s charge and, if you
experience brake fade or
receive a brake warning,
stop the vehicle and allow
the brakes to cool.
See“Charge Now” under
Charging 0123 for
information on setting
charge limits.
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Be sure to:
.Use regenerative braking to
help slow the vehicle or
maintain speed by keeping
the vehicle in gear and
limiting the initial battery
charge to 80% or less.
.When braking is necessary,
use frequent, light taps of
the brake pedal. This
maximizes regenerative
braking and minimizes the
load on the vehicle brake
system.
.Keep the vehicle serviced
and in good shape.
.Check all fluid levels, brakes,
tires and cooling system.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.

3. Drive slowly until the traileris clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance when Trailer
Towing
The vehicle needs service
more often when used to tow
trailers. See Maintenance
Schedule 0376. It is especially
important to check the cooling
system and brake system
before and during each trip.
Check periodically that all nuts
and bolts on the trailer hitch
are tight.
Cooling the Vehicle when
Trailer Towing
The cooling system may
temporarily overheat during
severe operating conditions.
See Cooling System 0313.
Trailer Towing
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle.
Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
and durability. Successful, safe
trailering takes correct
equipment, and it has to be
used properly. The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.
Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle.
Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.

Cooling System
It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise
is heard. A coolant loss could
indicate a problem. Have it
inspected and repaired by
your dealer.
During vehicle operation and
also during charging, the high
voltage battery cells in the
vehicle are kept within a
normal operating temperature
range. If the temperature rises
above this temperature, the
battery cooling system turns
on the air conditioning
compressor and cools the
coolant until the correct
temperature is reached. If the
temperature falls below this
temperature, a high voltage heater, located outside the
battery on a cradle, heats the
coolant until the correct
temperature is reached.
The cooling system allows the
vehicle to maintain the correct
working temperature.Checking Coolant
The coolant needs to be
replaced at the appropriate
interval. See Maintenance
Schedule
0376.
The coolant reservoir is in the
underhood compartment. See
Underhood Compartment
Overview 0312.
To access the coolant
reservoir under the hood, the
right side access cover needs
to be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood 0310.
3. The coolant reservoir is
under a cover and side
extension/shield in the
underhood compartment.
Unclip the right side of the
shield and remove the right
side access cover.
