Selectable drive modes: Certain
selectable drive modes may cause the
engine to run. See What Is Drive Mode
Control (page 329).
• Live in Drive: Use of the paddle shifters
while in drive (D) may cause the engine
to run.
See Automatic Transmission
(page 245).
Stopping
The gas engine may shut off to conserve fuel
as you come to a stop. Restarting your
vehicle is not required. Simply step on the
accelerator when you are ready to drive.
Transmission Operation
The engine and electric motor together
propel the vehicle through the automatic
transmission. This is normal hybrid operating
and helps deliver fuel efficiency and
performance. Battery
Your hybrid is equipped with a high voltage
battery. A cool battery maintains battery life
and provides the best possible performance.
The high voltage battery is cooled by the
vehicle's air conditioning system. When the
air conditioning system is on, you may notice
a slight increase in air temperature coming
from the climate control vents while the
battery is cooling. You may also notice cool
air flowing from the vents when the air
conditioning or blower is off.
Braking
Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in the high voltage battery.
You may also notice during extending
downhill driving that your engine continues
to run instead of shutting off. During this
engine braking, the engine stays on, but it is
not using any fuel. You may also hear a slight
whine or whistle when operating your
vehicle. This is the normal operation of the
electric motor in the hybrid system.
Driving to Optimize Fuel Economy
Note:
Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Your fuel economy should improve
throughout your hybrid's break-in period. As
with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep
these tips in mind:

Answer
Question
In order to make sure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as you request it, the engine coolant temperature has to be kept sufficiently hot. Keeping
the engine on is required to maintain the correct coolant temperature.
Why does my engine stay on when it is extremely cold outside?
Your hybrid vehicle can use E15 fuel (15% ethanol, 85% gasoline), butyou could notice slightly reduced fuel economy because ethanol
contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fuel
economy?
The high voltage battery system is designed to last the life of thevehicle and requires no maintenance.
How long will my high voltage battery last? Does it need maintenance?

Deep Sand (If Equipped)
For crossing deep soft and dry sand.
Note: Using deep sand mode on dry hard
surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.
Excite
For sporty on-road driving. This mode
increases throttle response, provides a more
dynamic powertrain sound and steering feel,
along with a more sporty shifting experience.
If your vehicle has continuously controlled
damping suspension it adjusts to a stiffer
suspension setting, with an emphasis on
handling and control. The transmission also
holds gears longer, helping your vehicle
accelerate faster when shifting gears.
If your vehicle has air suspension, it lowers
approximately
0.6 in (15 mm) to improve
aerodynamics. Normal
For everyday driving. This mode is a perfect
balance of excitement, comfort and
convenience. This is the default mode after
each ignition cycle.
Preserve EV
Your vehicle runs the engine as needed to
save electric driving range for later use in
another drive mode. For example, you first
drive at high speeds on open roads where
engine operation is appropriate. Later, you
drive at low speeds in an urban area where
electric only is most efficient.
See Plug-In
Hybrid Vehicle Operation (page 222).
Pure EV
This mode provides an electric only driving
experience. Your vehicle could accelerate
more slowly, and the top speed could
reduce. For more power, you can temporarily
enable your engine at any time by using one
of the following methods: •
Press and hold the folder button on the
steering wheel when viewing the pure
EV information screen. Your vehicle
enables the engine as needed, and
returns to pure EV after several seconds,
or when the vehicle no longer needs the
engine.
• Press the accelerator pedal fully. A
pop-up message appears. Press OK on
the steering wheel to activate as needed.
Your vehicle could enable the engine if
system conditions require it. An engine
enabled message displays if this occurs. See
Information Messages
(page 140).
Your engine could enable if the climate
control is in a defrost mode and the outside
temperature is cold. If the vehicle does not
need defrost, select a different climate
control mode to permit pure EV.
Your vehicle changes from pure EV mode to
normal mode when the vehicle electric range
is zero.
Note: When in pure EV mode, your vehicle
stays in this mode if there is all electric
driving range available and the system does
not fault.

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush.
You can neutralize the acid with a solution
of baking soda and water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:
If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of your
vehicle. If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Battery Management System (If Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some electrical systems to protect the
battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system. A message may appear in the information
displays to alert you that battery protection
actions are active. These messages are only
for notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time your vehicle must remain fully
locked with the ignition switched off.
Note:
Prior to relearning the battery state of
charge, the battery management system
may temporarily disable some electrical
systems.

contaminates which may cause engine
damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift through
all the gears while the engine is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the fuel
pump nozzle. Cooling system
•
Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling system
leaks and that fluid is at the
recommended level.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
battery cables to maintain battery charge
for quick starting.
Note: It is necessary to reset memory
features if you disconnect the battery cables.

As a result of the above dimensional
differences, sport utility vehicles and trucks
often have a higher center of gravity and a
greater difference in center of gravity
between the loaded and unloaded condition.
These differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.
TIRE CARE
Information About Uniform Tire Quality
Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires us to give you
the following information about tire
grades exactly as the government has
written it. Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear 1½ times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING:
The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
