STARTING AND STOPPING THE
ENGINE – FREQUENTLY ASKED
QUESTIONS - GASOLINE,
VEHICLES WITHOUT: PUSH
BUTTON START
Why is the engine idle speed high when
I am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank? You can only attempt to start the
engine for a limited amount of time
before the starting system temporarily
disables. If you exceed the starting
time limit, a message may appear and
you cannot attempt to start the engine
for at least 15 minutes.
Why do I experience different driving
characteristics? If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for
approximately 5 mi (8 km) after you
reconnect it. This is because the engine
management system must realign
itself with the engine. You can
disregard any unusual driving
characteristics during this period.
Why can I not start the engine? If you cannot start the engine after 3
attempts, wait 10 seconds and do the
following:
1. Fully press the brake pedal or the clutch pedal.
Note: Make sure that the parking brake is
applied.

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.

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:

FREQUENTLY ASKED QUESTIONS
Why does the engine not always
stop when I expect it to?
The system is designed to work in a way
that complements other vehicle systems,
allowing them to operate at optimum
performance.
The system does not stop the engine if:
•
The driver door is open.
• Your vehicle is at high altitude.
• The heated windshield is on.
• The engine is warming up.
• The outside temperature is too low or
too high.
• The battery charge is low.
• The battery temperature is outside the

• The engine is required to run to
maintain interior climate and reduce
fogging.
Why does the engine sometimes
restart when I do not expect it to?
The system is designed to work in a way
that complements other vehicle systems,
allowing them to operate at optimum
performance.
The system restarts the engine if:
• You switch the heated windshield on.
• You switch maximum defrost on.
• Your vehicle starts to roll downhill in
neutral.
• The engine is required to run to
maintain adequate brake system
assistance.
• The engine is required to run to
maintain interior climate and reduce
fogging. Can I permanently switch the
system off?
No. The system plays an important role in
reducing the fuel consumption and the CO
2
emissions.
Will the frequent engine starts
cause parts to wear out?
Your vehicle has an enhanced battery and
starter motor that are designed for the
increased number of engine starts.
