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.

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.

Question Answer
Why does my engine never shut
down above 40 mph (64 km/h)?The engine is required to turn on
above this speed to protect the
transaxle hardware.
Why does my engine stay ON
when it’s extremely cold outside?In order to ensure that the climate
control system can begin heating
the cabin and/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 minimum temperature.
Why does my engine rev up so
high sometimes when I accelerate?Your vehicle’s engine and
transmission are designed to
deliver the power you need at the
most efficient engine speed. This
may be higher than expected
during heavy accelerations, and
may fluctuate during steady state
driving. These are characteristics
of the Atkinson engine cycle and
the eCVT transaxle technology
that help maximize your hybrid’s
fuel economy.
What does it mean when my
power assist gauge moves to the
right? To the left?Electricity is coming out of the
battery when the gauge moves to
the right. Electricity is going into
the battery when the gauge moves
to the left.

DUAL AUTOMATIC TEMPERATURE CONTROL
1.AUTO/Driver temperature:Press to engage full automatic
operation. The system will automatically determine fan speed, airflow
distribution, A/C on or off, and outside or recirculated air, to heat or cool
the vehicle to reach the desired temperature. Turn to increase/decrease
the temperature on the driver side of the vehicle. The control also
adjusts the passenger side temperature when PASS TEMP is disengaged.
The recommended initial setting is between 72°F (22°C) and 75°F
(24°C), then adjust for comfort. The driver side temperature setting will
appear in the upper left corner of the display. The engine may run
continuously to provide A/C operation unless ECON mode is selected.
Selecting ECON mode affects A/C operation. Refer to ECON information
later in this section.
2.
RRear defroster:Press to activate/deactivate the rear window
defroster. Refer toRear window defrosterlater in this chapter for more

energy needed to keep the interior of the vehicle cool, and may also help
reduce undesired outside odors from reaching the interior of the vehicle.
Recirculated air is controlled automatically when AUTO is selected or
can be engaged manually in any airflow mode except
(defrost).
Recirculated air may turn off automatically in some airflow modes to
reduce window fogging potential. When the ignition switch is turned off
and back on, the climate system will return to the recirculated air mode
only if the A/C button LED is illuminated and the air distribution
selection is either AUTO,
(panel) or(panel/floor).
