.If the vehicle has heated seats,
and this feature has been
enabled through vehicle
personalization, the heated
seats will turn on during colder
outside temperatures. See
“Remote Start Heated Seats”
underHeated Front Seats on
page 3‑6 and“Remote Start
Auto Heated Seats” under
Vehicle Personalization on
page 5‑56 for additional
information.
.The rear defogger will turn on
during colder outside
temperatures.
.Selecting1during colder
outside temperatures before
shutting the vehicle off will help
windshield clearing.
.Shutting the vehicle off in ECO
Mode without
1selected will
minimize the impact to electric
range. Shutting the vehicle off in
other modes will maximize
heating or air conditioning.
.The engine may start to provide
energy for heating and cooling,
independent of the vehicle being
plugged in or completely
charged. Engine Assisted
Heating operation, if available,
can be personalized. See
“Engine Assisted Heating” under
Vehicle Personalization on
page 5‑56.
.Vehicle range may decrease if
the vehicle is not plugged into
an electrical outlet. If the vehicle
is plugged in, much of the
energy needed to support this
feature will be provided from the
utility, not from the high voltage
battery. Laws in some communities may
restrict the use of features that
remotely start the engine. For
example, some laws may require a
person using the remote start
feature to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
With the remote start feature, the
RKE transmitter functions will have
an increased range of operation.
However, the range may be less
while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System on page 2‑2
for additional
information.

Traction Control System
(TCS)/StabiliTrak®Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays on
while driving, there could be a
problem with the TCS/StabiliTrak
system and the vehicle might need
service. When this warning light is
on, the TCS/StabiliTrak system is off
and does not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop and turn off the vehicle to
avoid damage to the engine.
A warning chime sounds when this
light is on.
SeeEngine Overheating on
page 10‑21 for more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
in ON/RUN. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A message in the Driver Information
Center (DIC) may also display. See
Tire Messages on page 5‑55 for
more information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information Label. See
Tires on page 10‑44 for more
information.

Automatic Climate
Control System
The climate control buttons and the
touch screen are used to adjust the
heating, cooling, and ventilation. The vehicle may require the use of
an auxiliary heat source under
certain cold conditions. This
provides additional heating and
defrost capability obtained by
running the engine, even if the high
voltage battery is adequately
charged. Under these conditions,
the engine will start and use fuel.
Make sure there is fuel in the tank.
Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
being plugged in.

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 3‑6.
Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger turns off
automatically after about
five minutes. If turned on again, it
runs for about five minutes before
turning off. The defogger can also
be turned off by turning the
vehicle off.
For vehicles 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.
Notice: 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:
For vehicles 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.

Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑44.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest. Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving
—scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. See
“Mountain Mode” underDriver
Selected Operating Modes on
page 9‑25. Tips for driving in these
conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
electric drive unit.
.Keep the vehicle in gear when
going down steep or long hills.
{WARNING
Coasting downhill in N (Neutral)
or with the vehicle turned off is
dangerous. The brakes will have
to do all the work of slowing down
the vehicle and could become too
hot. Hot brakes may not be able
to slow the vehicle enough to
maintain speed and control. You
could crash. Always have the
vehicle running and in gear
(preferably LOW range) when
going downhill. This will allow the
electric drive unit to assist in
slowing and maintaining speed.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be
alert —something could be in
your lane (stalled car, accident).

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑12.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
