STARTING AND STOPPING THE
ENGINE – FREQUENTLY ASKED
QUESTIONS - DIESEL, VEHICLES
WITH: 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, do the
following:
1. Fully press the brake pedal or the clutch pedal.
Note: Make sure that the parking brake is
applied.
Note: Make sure that the transmission is in
park (P) or neutral (N). 2. Press the push button ignition switch
until the engine starts.
Why does the system not detect a
passive key?
If the system does not detect a passive
key and you are unable to start the
engine, insert the passive key into the
backup position and press the push
button ignition switch to start the
engine. See
Accessing the Passive
Key Backup Position (page 244).

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.

INFORMATION –
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:

What does it mean if the system
displays that it is not available?
There could be a sub-system that the
system uses that is not correctly
operating or there could be a battery
voltage issue. If the system continues
to display it is not available, visit your
authorized dealer to have your vehicle
checked.
What does it mean if the system
displays that driving is required to
initialize steering? The steering system needs to learn
internal parameters to fully turn on the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes. This could
also occur when your vehicle is new,
there is a battery voltage issue or if the
steering system has been serviced.
What does it mean if the system does
not detect a trailer when configured
with a sensor? Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 448). Repeat
calibration on a different route if you
have verified sensor installation.
What does it mean if the system
requires you to pull forward to
initialize? This occurs when the vehicle has not
moved during the current key cycle
after you connect and select the trailer
in the touchscreen or you operate the
system at speeds below
1 mph
(1 km/h) for an extended period of
time. Drive forward above 2 mph
(3 km/h) and the system indicates
when it initializes. What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle?
You are at the maximum controllable
trailer angle for the system. Place your
vehicle in drive (D) and pull forward to
get the truck and trailer back to an
in-line position. If this message
consistently displays, this could
indicate the sensor is incorrectly
installed, the trailer needs to be
recalibrated or the drawbar or the
trailer dimensions are outside of the
supported range. The system is
designed to work with drawbars that
have a license plate to hitch ball center
measurement of
9–18 in (23–46 cm)
when installed. The system is designed
to work with trailers that have a hitch
point to center of the axle or axles
measurement of
6– 33 ft
(1.85– 10.05 m). Do not attempt to use
drawbars or trailers that have a length
outside of this range as the system
performance degrades and could
cause improper system function.
Check that the correct trailer is
selected in the touchscreen. Verify the
sensor is installed according to the
instructions included in the sensor kit
and check that the drawbar and the
trailer dimensions are within the
allowed range. Then, delete the trailer
from the system and repeat the setup
process to calibrate the trailer.

HIGH VOLTAGE BATTERY
VEHICLE PRECAUTIONS -
HYBRID ELECTRIC VEHICLE
(HEV)
In the event of damage or fire involving an
electric vehicle or hybrid-electric vehicle:
• Assume the high-voltage battery and
associated components are energized
and fully charged.
• Physical damage to the vehicle or
high-voltage battery could result in
immediate or delayed release of toxic,
flammable gases and fire.
Crashes
A crash or impact significant enough to
require an emergency response for
conventional vehicles would also require
the same response for an electric or
hybrid-electric vehicle. If Possible:
1. Move your vehicle to a safe, nearby
location and remain on the scene.
2. Roll down the windows before you switch your vehicle off.
3. Place your vehicle in park (P), apply the parking brake, switch off the
vehicle, turn on the hazard flashers and
move the key at least 16 ft (5 m) away
from the vehicle.
Always:
• Call emergency assistance if needed
and advise that an electric or
hybrid-electric vehicle is involved.
• Avoid contact with leaking fluids and
gases, and remain out of the way of
oncoming traffic until emergency
responders arrive.
• When emergency responders arrive,
tell them that the vehicle involved is an
electric vehicle or hybrid-electric
vehicle.
Fires
As with any vehicle, call emergency
assistance immediately if you see sparks,
smoke or flames coming from the vehicle.
Remain a safe distance from the vehicle
and try to stay clear of the smoke.
1. Exit the vehicle immediately.
2. Advise emergency assistance that an electric or hybrid-electric vehicle is
involved.
3. As with any vehicle fire, do not inhale smoke, vapors or gas from the vehicle,
as they may be hazardous.
