Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help
maximize energy efficiency
and range.
Driving Style
Efficiency Gauge
(Instrument Cluster)
The ball indicator should be kept
green and in the center of the
gauge.
Inefficient acceleration is indicated
when the ball turns yellow and
travels above the center of the
gauge.
Aggressive braking is indicated
when the ball turns yellow and
travels below the center of the
gauge. Acceleration/Braking/Coasting
Avoid unnecessary rapid
accelerations and decelerations.
Electric range is maximized at
80 km/h (50 mph) and below.
Higher speeds use more energy
and can significantly reduce
electric range.
Use cruise control when
appropriate.
Plan ahead for decelerations
and coast whenever possible.
For example, do not rush to
traffic signals.
Do not shift to N (Neutral) to coast.
The vehicle recovers energy while
coasting and braking in D (Drive)
or L (Low).

Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these
deaths are the result of someone
who was drinking and driving.
In recent years, more than
17,000 annual motor vehicle-related
deaths have been associated with
the use of alcohol, with about
250,000 people injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem is
for people never to drink alcohol
and then drive.Medical research shows that
alcohol in a person's system
can make crash injuries worse,
especially injuries to the brain,
spinal cord, or heart. This means
that when anyone who has been
drinking
—driver or passenger —is
in a crash, that person's chance of
being killed or permanently disabled
is higher than if the person had not
been drinking.
Control of a Vehicle
The following three systems
help to control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of the
vehicle.
Adding non‐dealer accessories
can affect vehicle performance.
See Accessories and Modifications
on page 10‑4.
Braking
See Brake System Warning Light on
page 5‑24.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average reaction time is about
three‐fourths of a second. But that
is only an average. It might be less
with one driver and as long as two
or three seconds or more with
another. Age, physical condition,
alertness, coordination, and
eyesight all play a part. So do
alcohol, drugs, and frustration.
But even in three‐fourths of a
second, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft). That could be a lot of
distance in an emergency, so
keeping enough space between
the vehicle and others is important.

on. The flashing light will eventually
time out. The POWER
Obutton
light is on steady when in ON/RUN
power mode. When the vehicle is
turned off, the POWER
Obutton
light will turn off.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle
for the system to operate. If the
vehicle will not start, place the RKE
transmitter in the transmitter slot.
See Remote Keyless Entry (RKE)
System Operation on page 2‑3.
ON/RUN: This position is for
driving and starting. With the vehicle
off, and the brake pedal applied,
pressing the POWER
Obutton once
will place the vehicle in ON/RUN.
The instrument cluster displays an
active fuel or battery gauge, along
with an audio startup cue, when
the vehicle is ready to be driven.
This could take up to 15 seconds
at extremely cold temperatures. The engine will only start if needed.
If the vehicle did not start, the
instrument cluster will display a
screen with inactive fuel and battery
gauges. See
Starting and Stopping
the Vehicle on page 9‑20.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of
the MIL as may be required for
emission inspection purposes.
With the vehicle off, and the brake
pedal not applied, pressing and
holding the POWER
Obutton for
more than 5 seconds will place
the vehicle in Service Only Mode.
The instruments and audio systems
will operate as they do in ON/RUN,
but the vehicle will not be able to be
driven. The propulsion system will
not start in Service Only Mode. STOPPING THE VEHICLE/OFF:
To turn the vehicle off, push the
POWER
Obutton with the vehicle
in P (Park). Retained Accessory
Power (RAP) will remain active
until the driver door is opened.
See Retained Accessory Power
(RAP) on page 9‑22. When turning
off the vehicle, if the vehicle is not
in P (Park), the vehicle will go to
ACC/ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Electric Drive Unit Messages
on page 5‑47.
In an emergency, if the vehicle must
be stopped while driving:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.

Electric Mode
In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered
by electrical energy stored in the
high voltage battery. The vehicle
can operate in this mode until the
battery has reached a low charge.
There are some conditions when
the battery charge is high enough
to provide Electric Mode operation,
but the engine still runs. They are:
.Cold ambient temperatures.
.Hot or cold high voltage battery
temperatures.
.The hood being open or not
completely closed and latched.
.Certain high voltage battery fault
conditions.
.Engine Maintenance Mode
or Fuel Maintenance Mode
being run.
Extended Range Mode
When the vehicle reaches the end
of its electric range, it switches
to Extended Range Mode (ERM).
In this secondary mode, electricity
is produced by the fuel‐powered
engine. This secondary source of
electric power extends the vehicle
range. Operation will continue
in ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power
and work together with the engine
to provide peak performance when
it is required, such as driving up a
steep incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine.In either Electric Mode or Extended
Range Mode, when the hood is
open, the engine will run without
turning off if the vehicle is on.
The high voltage battery is neither
charged nor discharged when this
occurs.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine
may run without turning off to
generate needed electricity.
The Malfunction Indicator Lamp
will turn on. See
Malfunction
Indicator Lamp on page 5‑21.

can then be selected again as
desired.
During some conditions, certain
drive modes may be unavailable.
The unavailable mode is grayed
out in the DIC menu and cannot
be selected.
If in Sport or Mountain Mode,
either may become unavailable and
the vehicle will return to Normal
Mode. The indicator light goes
off and a DIC message displays.

Press the Drive Mode button again
to return to Normal Mode and it
becomes active in three seconds.
If Mountain Mode is not selected
for these conditions, propulsion
power may be reduced and the
engine speed may increase. See
Propulsion Power Messages on
page 5‑50.
The vehicle returns to Normal Mode
at each start to maintain a smaller
battery charge reserve for normal
driving.
Out of Fuel/Engine
Unavailable
If the vehicle runs out of fuel,
or the engine will not start due
to a malfunction, the vehicle can
continue to be driven in Electric
Mode. The vehicle will have
less responsive acceleration.DIC messages indicate reduced
propulsion power, that the engine
is not available, and the need for
fuel or service.
Once the vehicle is refueled, or the
malfunction is corrected, the engine
will start the next time the vehicle is
turned on to perform a self test, and
DIC messages will not be displayed.
Once the engine starts successfully,
normal operation will continue in
either Electric or Extended Range
Mode. The engine will stop running
after the self test is completed,
and based on the current mode
of operation. See
Fuel System
Messages on page 5‑48 and
Service Vehicle Messages on
page 5‑51.
Maintenance Modes
Engine Maintenance Mode (EMM)
Engine Maintenance Mode
(EMM) runs the engine to keep
it in good working condition after
approximately six weeks of no or
very limited engine operation. EMM
will force the engine to run, even
if there is a charge to power the
vehicle. When EMM is needed,
the EMM Request screen appears
on the center stack display at
vehicle start.
If Yes is selected, EMM will begin.
The engine will run for a set
amount of time without turning off.
