HYBRID OPERATION
The Hybrid is a whole new kind of SUV that combines electric and
gasoline propulsion without compromise, to provide breakthrough
performance and efficiency. It requires no special fuels and never has to
be plugged in. Familiarizing yourself with these unique characteristics
will help ensure optimal performance from your new vehicle.
Normal vehicle operation
Starting:Turn the ignition key to the START position while your vehicle
is in Park (P). The gas engine will turn on,accompanied by the green
“ready indicator” light. Your engine may shut off shortly after starting,
depending on temperature and battery charge level. This is a natural
part of your Hybrid’s fuel-saving features. The “ready indicator” light will
stay on, and you do not need to restart the vehicle.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin for
occupant comfort.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the vehicle operates in electric-only mode. Conditions that
cause the engine to start up or remain running include:
•Driving request for moderate to rapid acceleration
•Vehicle speed above 40 mph (65 kph)
•Ascending a hill
•ECON mode not selected (while Climate Control is ON)
•Selection of climate control defrost mode or defrost/floor mode
•Charge level of high voltage battery is low
•Very high or low outside temperature (to provide system
cooling/heating)
Stopping:The gas engine may shut off to conserve fuel as you come to
a stop. Restarting the vehicle is not required. Simply step on the
accelerator when you are ready to drive.
Transmission Operation:Due to the technologically advanced,
electronically controlled Continuously Variable Transaxle (eCVT) you will
not feel shift changes like those of a non-hybrid vehicle. Your Hybrid’s
transmission is designed to do its work seamlessly.
Since your engine speed is controlled by the transmission, it may
seem elevated at times. This is normal hybrid operation and helps
deliver fuel efficiency and performance.

Neutral:It is not recommended to idle the vehicle in (N) Neutral for
extended periods of time because this will discharge your high voltage
battery and decrease fuel economy. Also, the engine cannot provide
power to the hybrid system in (N) Neutral.
Low Gear:Low gear (L) is designed to mimic the enhanced engine
braking available in non-hybrid vehicles. On long downhill grades, (L)
Low gear may produce high engine speeds to provide necessary engine
braking. This is normal and will not damage your vehicle. Response
during acceleration should be the same as in the (D) Drive position.
Reverse:(R) Reverse Gear vehicle speed is limited to 22 mph
(35 km/h).
Unique Hybrid operating characteristics
Your Hybrid, with its new technology, behaves differently compared to a
non-hybrid. Here is a description of the major differences:
Battery:Your Hybrid is equipped with a high voltage battery cooling
system in the rear of the vehicle. A cool battery ensures battery life and
provides the best possible performance. Your hybrid high voltage battery
may periodically re-condition itself to ensure maximum efficiency. You
may notice slight changes in drivability during this process, but it’s an
important part of your Hybrid’s high voltage battery optimization
features.
You may hear a series of clicks from the cargo area when you first turn
the key in the ignition. This sound is the high voltage contactors closing
to allow you to start your hybrid.
In addition, you may hear fan noise and a slight tapping sound from the
rear as the vent door operates. This fan may continue to operate for
short durations after the vehicle has been turned off. These noises are a
customary part of hybrid operation and do not require service.
If the vehicle is left inoperative for over 31 days, it may be necessary to
jumpstart the vehicle. For more information, refer toJump starting
your (Low voltage [underhood] battery only)in theRoadside
Emergencieschapter.
Engine:The engine speed in your hybrid is not directly tied to your
vehicle speed. Your vehicle’s engine and transmission are designed to
deliver the power you need at the most efficient engine speed. During
heavy accelerations, your hybrid may reach high engine speeds (up to
6000 RPM). This is characteristic of the Atkinson cycle engine
technology helping to maximize your hybrid’s fuel economy.

Introduction

In prolonged mountainous driving, you may see the engine tachometer
changing without your input. This is intentional and maintains the
battery charge level. You may also notice during extended downhill
driving that your engine continues to run instead of shutting off.
During this “engine braking”, the engine stays on, but it’s 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 generator in the
hybrid system.
During certain events (such as vehicle servicing) your low voltage
(underhood) battery may become disconnected or disabled. When this
occurs, and after reconnecting the low voltage (underhood) battery and
driving the vehicle, the engine may continue to operate for 3-5 seconds
after the key is turned to the 1 (LOCK) position. This is a normal
condition, as the vehicle’s computers are relearning the operating
characteristics of your particular engine in order to operate it at
maximum efficiency.
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 your high
voltage battery.
You may hear a pumping sound when you unlock or enter the vehicle
and a venting sound a few minutes after shutting off the vehicle. This is
the hydraulic portion of your regenerative braking system charging and
discharging.
Driving to optimize fuel economy
Your fuel economy should improve throughout your hybrid’s break-in
period. As with any vehicle, fuel economy can be significantly impacted
by your driving habits and accessory usage. For best results, keep in
mind these tips:
Tire Inflation:Keep tires properly inflated and only use recommended
size.
Climate Control:Your hybrid is equipped with an “ECON” button that
offers a more fuel efficient operation of your automatic temperature
control system.
When activated, the “ECON” feature allows the engine to shut down at
low speeds or when your vehicle is stopped.
If cooler temperature is desired, the “ECON” button can be turned off,
for better interior cooling but lower fuel economy.

Frequently asked questions
Question Answer
What is the pumping sound I hear
when I unlock or enter the vehicle,
and the venting sound a few
minutes after shutting off my
vehicle?This is the hydraulic portion of
your regenerative braking system
pressurizing and depressurizing.
You may also hear it occasionally
after pressing the brake pedal.
What are the series of clicks from
the cargo area when I first turn
the key in the ignition?The high voltage battery is
electrically isolated from the rest
of the vehicle when the key is
OFF. When the key is turned ON,
high voltage contactors inside the
battery are closed to make the
electricity available to the
motor/generator and enable the
vehicle to drive. The clicks are the
sound of these contactors as they
close and open during start up and
shut down.
Why does the engine always start
at key-on?Your engine is started at key-on
because the emission components
need to be warm in order to
minimize tailpipe emissions, and in
cooler climates for cabin heating
and windshield defrost
performance.
After I start my car in the
morning, 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 it is first
started. One common reason is to
ensure that the emissions
components are warm enough to
minimize tailpipe emissions. As the
climate gets cooler, this
“engine-ON” time is extended.
