WHAT IS A HYBRID ELECTRIC
VEHICLE
A hybrid vehicle has an electric motor and
a high voltage battery combined with a
gasoline engine.
HOW DOES A HYBRID
ELECTRIC VEHICLE WORK
The hybrid vehicle combines electric and
gasoline propulsion to provide optimal
performance and improved efficiency.
HYBRID ELECTRIC VEHICLE
DRIVING CHARACTERISTICS
The gasoline engine starts and stops to
provide power when required and to save
fuel when not needed. When coasting at
low speeds, coming to a stop or standing,
the gas engine normally shuts down and
your vehicle operates in electric-only
mode.
Conditions that may cause the gasoline
engine to start or remain running include:
•
Considerable vehicle acceleration.
• Driving uphill.
• The high voltage battery charge level
is low.
• Heating or cooling the vehicle interior
in high or low outside temperatures.
• The gasoline engine is below normal
operating temperature.
• Towing a trailer.
• Certain selectable drive modes could
cause the engine to run. See Selecting
a Drive Mode (page 373). Use of the
paddle shifters while in drive (D) could
cause the engine to run. Your hybrid vehicle also comes with
standard hydraulic braking and
regenerative braking. Regenerative braking
is performed by your transmission and
captures brake energy and stores it in the
high voltage battery.
You could also notice that your engine
continues to run instead of shutting off
during extended downhill driving. The
engine stays on during this engine braking
but is not using any fuel.
You could also hear a slight whine or
whistle when operating your vehicle. This
is the normal operation of the electric
motor in the hybrid system.
HYBRID ELECTRIC VEHICLE
INDICATORS
When you start your vehicle, a
green READY indicator light
appears in the instrument cluster
letting you know that your vehicle is ready
for driving.
The engine may not start because your
vehicle has a silent key start feature. This
fuel saving feature allows your vehicle to
be ready to drive without requiring the gas
engine to be running.
The indicator remains on when your vehicle
is on, whether the engine is running or not,
to indicate your vehicle is capable of
movement using the electric motor, gas
engine or both.
Typically, the engine does not start unless
the vehicle is cold, a climate control
change is requested or you press the
accelerator pedal.

TROUBLESHOOTING
HYBRID ELECTRIC VEHICLE
INFORMATION – FREQUENTLY
ASKED QUESTIONS
How long is the high voltage battery
system designed to last?
The high voltage battery system is
designed to last the life of your vehicle.
Does the high voltage battery require
maintenance? The high voltage battery does not
require maintenance.
What should I do if the vehicle runs out
of fuel and the high voltage battery is
out of charge? Refuel and start your vehicle normally.
The engine will recharge the high
voltage battery.
Why does the engine sometimes start
at key-on? The vehicle's computer will determine
if an engine start is required at key-on.
It starts the engine when necessary for
cabin heating, windshield defrost, or if
the outside temperature is low.
Can I put E15 or E85 in my vehicle, and
how will it affect my fuel economy? Your hybrid vehicle can use E15 (15%
ethanol, 85% gasoline) fuel, but you
may 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). Why does it take a long time before the
engine shuts down?
There are several reasons the engine
stays on for an extended amount of
time when you first start it. One
common reason is to make sure that
the emissions components are warm
enough to minimize tailpipe emission.
As the climate gets cooler, the
engine-on time is extended.
Why does my engine stay on when it is
extremely cold outside? In order to make sure that the climate
control system can begin heating the
cabin or defrosting the windshield as
soon as a driver requests it, the engine
coolant temperature has to be kept
sufficiently hot. Keeping the engine on
is required to maintain the correct
coolant temperature.
ECO IDLE
WHAT IS ECO IDLE
Eco idle reduces fuel consumption when
your vehicle is in park (P) and idling for long
periods of time. Eco idle more efficiently
extends the use of features that are
powered by the high voltage battery when
your vehicle is stationary.
HOW DOES ECO IDLE WORK
Eco idle increases the engine idle speed
above normal for a short period of time to
efficiently charge the high voltage battery.
Note: Engine sound and vibration could be
more noticeable.
SWITCHING ECO IDLE ON AND OFF
To switch eco idle on and off use the
touchscreen:

TOWING YOUR VEHICLE
PRECAUTIONS
Use the following guidelines when towing
your vehicle. Failure to follow this
instruction could result in vehicle damage
not covered by the vehicle warranty.
Note:
Make sure you properly secure your
vehicle to the tow vehicle.
Note: If you are unsure of the vehicle ’s
configuration, contact an authorized dealer.
RECREATIONALLY TOWING
YOUR VEHICLE - 4X4 WARNING: Do not disconnect the
battery when recreationally towing your
vehicle. This prevents the transfer case
from shifting properly and could cause
the vehicle to roll, even if the
transmission is in park (P). WARNING:
Placing the transfer
case in its neutral position could cause
your vehicle to freely roll. Make sure you
press and hold the brake pedal and the
vehicle is in a secure, safe position when
you place the transfer case in its neutral
position.
Follow these guidelines if you have a need
for recreational towing. An example of
recreational towing would be towing your
vehicle behind a motorhome. These
guidelines are to make sure that you do
not damage the transmission. You can only tow your vehicle with all
wheels on the ground by placing the
transfer case in its neutral position and
engaging the recreational tow feature.
Perform the following steps after
positioning your vehicle behind the tow
vehicle and properly securing them
together.
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
Note: Failure to put the transfer case in its
neutral position can damage vehicle
components.
Note: You can check the towing status at
any time by opening the driver door or
turning the ignition to the accessory or on
position. Neutral Tow Enabled Leave
Transmission in Neutral
appears in the
instrument cluster display to confirm you
can recreationally tow your vehicle.
Note: If your vehicle has an anti-theft
alarm, make sure you switch perimeter
sensing on when towing. See
Setting the
Alarm Security Level (page 135).
Switching
Neutral Tow On
1. Start your vehicle.
2. Press the 2H button on the four-wheel
drive mode control.
3. Place your vehicle in temporary neutral
mode. See
Entering Temporary
Neutral Mode (page 286).
4. Switch your vehicle off by pressing the
push button ignition switch once or
turning the key as far toward the off
position as possible. A message
appears in the instrument cluster
display.

Note:
To calibrate the steering angle
sensor, drive the vehicle above 30 mph
(50 km/h) for a minimum of 1.2 mi (2 km).
Make sure to drive straight ahead for a
minimum of 30 seconds. Several vehicle
functions are disabled and a warning light
could appear until the sensor is calibrated.
Battery Management System
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 of the following features:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active.
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 off.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
Battery Disposal Make sure that you dispose of
old batteries in an
environmentally friendly way.
Seek advice from your local authority
about recycling old batteries. ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident,
contact an authorized dealer to check and
realign your headlamps.

PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30
days or more, the following maintenance
recommendations ensures your vehicle
stays in good operating condition.
Under various conditions, long-term
storage may lead to degraded engine
performance or failure unless you use
specific precautions to preserve your
vehicle.
General
•
Store all vehicles in a dry, ventilated
place.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and weather damage.
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminants 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. Body
•
Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housings
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Hybrid Battery Systems
We recommend the following actions for
your vehicle:
• When storing your vehicle for greater
than 30 days the state of charge
should be approximately 50%.
Additionally we recommend
disconnecting the 12V battery which
will reduce system loads on the HV
battery.
12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
Note: It is necessary to reset memory
features if you disconnect the battery
cables.
Brakes
Make sure the brakes and parking brake
release fully.

DEPARTMENT OF
TRANSPORTATION UNIFORM
TIRE QUALITY GRADES 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.
