HYBRID VEHICLE OPERATION
- 3.3L, HYBRID ELECTRIC
VEHICLE (HEV)
This hybrid vehicle combines electric and
gasoline propulsion to provide
breakthrough performance and improved
efficiency. Familiarizing yourself with these
unique characteristics provides an optimal
driving experience from your vehicle.
Starting
When you start your vehicle, a
green READY indicator light
appears in the instrument cluster
and a ready to drive message appears,
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.
Driving
The gas engine starts and stops to provide
power when needed 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 engine to
start up or remain running include:
• Considerable vehicle acceleration.
• Climbing a hill. •
Charge level of high voltage battery is
low.
• High or low outside temperatures to
provide system heating or cooling.
• Engine is not warm enough to provide
passenger requested cabin
temperature.
• Towing a trailer.
• Selectable drive modes: Certain
selectable drive modes could cause
the engine to run.
• Live in Drive: Use of the paddle shifters
while in drive (D) could cause the
engine to run.
Stopping
The gas engine may shut off to conserve
fuel as you come to a stop. You do not
need to restart your vehicle. 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 has a high voltage battery. A
cool battery maintains battery life and
provides the best possible performance.
The vehicle's air conditioning system cools
the high voltage battery. 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.

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.
Braking
Your hybrid has standard hydraulic braking
and regenerative braking. Your
transmission performs regenerative
braking by capturing brake energy and
storing it in the high voltage battery. You
may notice the transmission changing
gears while decelerating. This is normal
and captures the maximum energy back
into the high voltage battery.
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
is not using any fuel.
Driving to Optimize Fuel Economy
Note:
Having your engine running is not
always an indication of inefficiency. In some
cases, it is more efficient than driving in
electric mode. Fuel economy improves 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:
•
Keep the tires properly inflated and
only use the recommended size.
• Aggressive driving increases the
amount of energy required to move
your vehicle. In general, you can
achieve better fuel economy with mild
to moderate acceleration and
deceleration. Moderate braking is
particularly important since it allows
you to maximize the energy captured
by the regenerative braking system.
Additional Tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits.
• Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS - 3.3L,
HYBRID ELECTRIC VEHICLE (HEV)
Answer
Question
The high voltage battery is electrically isol-ated from the rest of the vehicle when the
key is off. When you switch the key on, high voltage contactors inside the battery are
closed to make the electricity available to the motor and 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.
What are the series of clicks from the cargo
area when I first turn the key in the ignition?
The vehicle's computer will determine if an
engine start is required at key-on. Silent keystart will start the engine if it is necessaryfor cabin heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at
key-on?
There are several reasons the engine stayson 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
emissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the
engine shuts down?
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 main- tain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?

Answer
Question
Change the engine oil according to your
Intelligent Oil-Life Monitor recommenda-
tion which under normal driving conditions should be around 9,500 mi (15,288 km)-
12,500 mi (20,117 km) See Scheduled
Maintenance (page 487).
What is the engine oil change service
interval?
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).
Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?
The high voltage battery system is designedto last the life of the vehicle and requires no maintenance.
How long will my high voltage battery last?
Does it need maintenance?

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
