3. Remove all objects from the chargingpad. The system may not charge if there
are any objects between the smartphone
and charger.
4. Place the smartphone face up against the rubber charge mat in between the
two small vertical rubber ribs.
To maximize the charge 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. 5. A green
]will appear on the
infotainment display, next to the phone
icon. This indicates that the smartphone
is on the charger. The green
]will
remain on while the phone is charging.
6. If a smartphone is placed on the charger and
]turns off or a yellow triangle
appears, remove the smartphone and
any objects from the pad. Turn the
smartphone 180 degrees and wait a few
seconds before placing/aligning it on the
pad again. If the status stays yellow,

VehicleTExit Lighting.
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 the state 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 Center
(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. In some cases, it can temporarily
reduce the power demands of some
accessories.
These actions occur in steps or levels
without being noticeable. In rare cases at
the highest levels of corrective action, this
action may be noticeable to the driver. If so,
a DIC battery voltage and charging message
displays. It is recommended that the driver
reduce the electrical loads as much as
possible. See
Driver Information Center (DIC)
(Base Level) 0129 or
Driver Information Center (DIC) (Uplevel)
0 130.
Battery Power Protection
This feature helps prevent the battery from
being drained if the interior courtesy lamps
or reading lamps are accidentally left on.
If any of these lamps are left on, they
automatically turn off after 10 minutes when
the vehicle is turned off. The lamps will not
come back on again until one of the
following occurs:
.The vehicle is started.
.The doors are closed and then re-opened.

Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help maximize
energy efficiency and driving range.
The Energy Usage card available on the
Driver Information Center (DIC) estimates
the influence of the main factors impacting
vehicle range. It displays how energy is
being used for the current drive
as percentages of overall vehicle energy use.
See Driver Information Center (DIC) (Base
Level) 0129 or
Driver Information Center (DIC) (Uplevel)
0 130 and
Vehicle Status 0132.
Acceleration/Braking/Coasting
Avoid rapid accelerations and decelerations.
Driving range is maximized at 89 km/h
(55 mph) and less.
Use cruise control when appropriate.
Using the steering wheel paddle during
deceleration recovers more energy. See
Regenerative Braking 0206. Terrain and Vehicle Speed
Plan ahead for decelerations and coast
whenever possible. Do not rush to traffic
signals. Do not shift to N (Neutral) to coast.
Higher speeds and grade changes use more
energy and can significantly reduce driving
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 seat features instead of
climate control system. Heating the seat
uses less energy than heating and cooling
the interior.
Use remote start to heat or cool the interior
when the vehicle is plugged in to maximize
the driving range by using electricity from
the electrical outlet.
In hot weather, avoid parking in direct
sunlight or use sunshades inside the vehicle.

Driving and Operating 191
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. See
Regenerative Braking0206.
.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.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0°C
(32°F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Turn off cruise control.
.If enabled, turn off One-Pedal Driving. See
One-Pedal Driving 0203.
.If turned off, turn on the Traction Control
System (TCS) and Electronic Stability
Control (ESC). See Traction Control/
Electronic Stability Control 0207.
.Select the Snow/Ice driver mode. See
Driver Mode Control 0209.
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0204.
.Avoid using the Regen on Demand
paddle. See Regenerative Braking 0206.
Blizzard Conditions
If you become stranded or cannot continue
driving due to winter storm conditions, stop
the vehicle in a safe place and signal for
help. If possible, use Roadside Assistance
Program 0399. Stay with the vehicle unless
there is help nearby.

Pulling the Trailer from the Water1. Press and hold the brake pedal.
2. Start the vehicle and shift into D (Drive) or L (Low).
3. Release the parking brake.
4. Let up on the brake pedal.
5. Drive slowly until the tires are clear of the chocks.
6. Stop and have someone pick up and store the chocks.
7. Slowly pull the trailer from the water.
Caution
If the vehicle tires begin to spin and the
vehicle begins to slide toward the water,
remove your foot from the accelerator
pedal and apply the brake pedal. Seek
help to have the vehicle towed up
the ramp.
Maintenance when Trailer Towing
The vehicle needs service more often when
used to tow trailers. See Maintenance
Schedule 0389. 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.
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, and how frequently the vehicle
is used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle,
including:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Maximum Trailer Tongue Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
See “Weight-Distributing Hitch and
Adjustment” underTowing Equipment 0301
to determine if equalizer bars are required
to obtain the maximum trailer weight
rating.

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.
The following explains the cooling system
and how to check coolant level.
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.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See
Maintenance
Schedule 0389.
The coolant reservoir is in the underhood
compartment. See Underhood Compartment
Overview 0325.
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 Hood019.
3. Turn the three bolts three quarter turn
and remove the right side access cover.
