MAUTO/LAUTO (Auto Heated
Seats): If available, the controls
are on the touch screen on the
center stack.
Press the touch screen
LAUTO or
MAUTO button. The button color
will change to green when this
feature is on. When the vehicle is
on, this feature will automatically
activate the heated seats at the
level required by the vehicle's
interior temperature. The active
high, medium, low, or off heated
seat level will be indicated by the
manual heated seat button lights on
the center stack. Use the touch
screen buttons or the manual
heated seat buttons on the center
stack to turn auto heated seats off.
For more information, see Heated
Front Seats on page 3-5.
Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on. The defogger only works when the
vehicle is in ON/RUN. The defogger
will turn off if the vehicle is
turned off.
If equipped with heated outside
rearview mirrors, they turn on when
the rear window defogger button is
on and help to clear fog or frost from
the surface of the mirror. See
Heated Mirrors on page 2-17.
{Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
Remote Start: If equipped with this
feature, the climate control system
may be started by using the Remote Keyless Entry (RKE) transmitter.
The climate control system will
default to an appropriate heating or
cooling mode. See
Remote Start on
page 2-8.
The rear window defogger turns on
if it is cold outside.
Compressor
The vehicle has an electric powered
air conditioning compressor. This
allows for continuous air
conditioning and/or high voltage
battery cooling operation, without
running the engine.
The compressor operating speed is
not tied to the engine speed, so
some noise may be heard from the
compressor, especially when air
conditioning use is high and the
engine has turned off. This is
normal.

Sport Mode provides more
responsive acceleration than
Normal Mode but can reduce
efficiency.
Use Mountain Mode prior to
climbing long, steep grades in
mountainous areas. Be sure to
engage Mountain Mode before
starting to climb. Mountain Mode
reduces electric range and power
but may be needed to maintain
speeds above 96 km/h (60 mph)
when climbing grades of 5% or
greater.
Use Hold Mode on a trip where all
or most of the electric charge will be
depleted. Use Hold Mode mainly
during highway or high speed
driving to maximize both EV miles
and fuel efficiency.
Use L (Low) in heavy stop-and-go
traffic or when traveling downhill.
L (Low) requires less brake pedal
application and provides a
controlled, efficient way to slow the
vehicle down.Climate Setting
Using the heat and air conditioning
systems decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved with the heat, air
conditioning, and fan turned off.
Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
.ECO is for moderate air
conditioning and heater
operation and is the next most
energy efficient setting as long
as
0is not selected.
.Comfort provides the most
comfort but is the least energy
efficient.
Use the auto heated seat feature
instead of climate settings. Heating
the seat uses less energy than
heating the vehicle interior. Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet.
Engine Assisted Heating operation,
if equipped, can be personalized.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
See
Vehicle Personalization on
page 5-50.Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.

Driving and Operating 9-7
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator andthen, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other material on the road. Learn to
recognize warning clues
—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
.Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.

9-10 Driving and Operating
The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but
apply the brakes sooner than when
on dry pavement.
Allow greater following distance on
any slippery road 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.
Turn off cruise control on slippery
surfaces.Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use the Roadside
Assistance Program. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.(Continued)
Warning (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of the vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.(Continued)

9-24 Driving and Operating
Mountain Mode
Mountain Mode should be selected
at the beginning of a trip before
climbing steep, uphill grades and
when expecting to drive in very hilly
or mountainous terrain. This mode
maintains a reserve electrical
charge of the high voltage battery to
provide better grade climbing
performance. While driving in
Mountain Mode, the vehicle will
have less responsive acceleration.
Mountain Mode will not change
normal vehicle braking performance
for steep downhill grades. SeeHill
and Mountain Roads on page 9-9
and Electric Drive Unit on
page 9-28. Press the DRIVE MODE button to
select Mountain Mode. If steep hill
driving is expected, it is
recommended to select Mountain
Mode at least 20 minutes before
driving on steep grades. This will
allow the vehicle time to build a
sufficient battery charge reserve.
If Mountain Mode is not selected for
these conditions, propulsion power
may be reduced and the engine
speed may increase. See
Propulsion Power Messages on
page 5-47.
The engine may run when Mountain
Mode is selected, depending on
high voltage battery charge, to build
reserve battery charge for uphill
climbs. If Mountain Mode is entered
with a sufficient battery charge
reserve, the battery charge reserve
will appear grayed out and any
battery charge reserve still unused
upon exiting Mountain Mode will
return to normal appearance.
Press the Drive Mode button again
to return to Normal Mode and it
becomes active after three seconds.
The Mountain light comes on when
Mountain Mode is selected. See
Mountain Mode Light on page 5-21.
Each time the vehicle is started, it
will return to Normal Mode to
maintain a smaller battery charge
reserve for normal driving.Hold Mode
Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting this

mode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.
Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Hold Mode will not change normal
vehicle acceleration or braking
performance.
Press the DRIVE MODE button to
select Hold Mode.
Press the DRIVE MODE button
again to return to Normal Mode and
it becomes active after
three seconds.
The Hold light comes on when Hold
Mode is selected. SeeHold Mode
Light on page 5-21.
Each time the vehicle is started, it
will return to Normal Mode.Out of Fuel/Engine
Unavailable
If the vehicle runs out of fuel, or the
engine will not start due to a
malfunction, the vehicle can
continue to be driven in Electric
Mode. The vehicle will have less
responsive acceleration. DIC
messages indicate reduced
propulsion power, that the engine is
not available, and the need for fuel
or service.
Once the vehicle is refueled, or the
malfunction is corrected, the engine
will start the next time the vehicle is
turned on to perform a self test, and
DIC messages will not be displayed.
Once the engine starts successfully,
normal operation will continue in
either Electric or Extended Range
Mode. The engine will stop running
after the self test is completed, and
based on the current mode of
operation. See Fuel System
Messages on page 5-44 and
Service Vehicle Messages on
page 5-48.
Maintenance Modes
Engine Maintenance Mode (EMM)
EMM runs the engine to keep it in
good working condition after
approximately six weeks of no or
very limited engine operation. EMM
will force the engine to run, even if
there is a charge to power the
vehicle. When EMM is needed, the
EMM Request screen appears on
the center stack display at vehicle
start.
If Yes is selected, EMM will begin.
The engine will run for a set amount
of time without turning off. During

shifting from P (Park) when the
vehicle is in ON/RUN. If you cannot
shift out of P (Park), ease pressure
on the shift lever, then push the shift
lever all the way into P (Park) as
you maintain brake application.
Then press the shift lever button
and move the shift lever into
another gear. SeeShifting out of
Park on page 9-20.
R (Reverse): Use this gear to
back up.
{Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the electric drive unit.
The repairs would not be covered
by the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the electric drive unit, see
If the Vehicle Is Stuck on page 9-11. N (Neutral):
In this position, the
propulsion system does not connect
with the wheels.
D (Drive): This position is for
normal driving. It provides the best
fuel economy. If more power is
needed for passing, and the
vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
{Caution
If the vehicle seems to accelerate
slowly or not respond when you
go faster, and you continue to
drive the vehicle that way, you
could damage the electric drive
unit. Have the vehicle serviced
right away. L (Low):
This position reduces
vehicle speed without using the
brakes. Use L (Low) on very steep
hills, in deep snow, in mud, or in
stop-and-go traffic.
{Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the electric drive
unit. The repair will not be
covered by the vehicle warranty.
If you are stuck, do not spin the
tires. When stopping on a hill, use
the brakes to hold the vehicle in
place.
