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 ofelectric 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 malfunctionindicator lamp will turn on. See
Malfunction Indicator Lamp on
page 5-17.
Driver Selected Operating
Modes
While driving in Electric or Extended
Range Mode, additional operating
modes can be selected.
Press the MODE switch to display
selectable drive modes in the Driver
Information Center (DIC). Continue
pressing to scroll through the
modes.

Pressing the MODE switch again
will return to Tour Mode, and
become active after three seconds.
At next start, the vehicle will default
to Tour Mode. Drive modes 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, Mountain, or Hold Mode,
the mode may become unavailable
and the vehicle will return to Tour
Mode. The indicator light goes off
and a DIC message displays. See

but can reduce efficiency. Use Tour
Mode whenever possible.
Press the MODE switch button to
select Sport Mode.
Press the MODE switch again to
return to Tour Mode and it becomes
active after three seconds.
Each time the vehicle is started, it
will return to Tour Mode.
Mountain Mode
Mountain Mode should be selected
in advance of climbing steep, uphill
grades and when expecting to drive
in very hilly or mountainous terrain.
This mode maintains a reserve
electrical charge of the high voltage
battery to provide better grade
climbing performance. While driving
in Mountain Mode, the vehicle will
have less responsive acceleration.

Mountain Mode will not change
normal vehicle braking performance
for steep downhill grades. SeeHill
and Mountain Roads on page 9-9
and Electric Drive Unit on
page 9-28.
Press the MODE switch to select
Mountain Mode. If steep hill driving
is expected, it is recommended to
select Mountain Mode at least
20 minutes before driving on steep
grades. This will allow the vehicle
time to build a sufficient battery
charge reserve.
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 5-48.
The engine may run when Mountain
Mode is selected, depending on the
high voltage battery charge, to build
reserve battery charge for uphill
climbs. The high voltage battery
charge reserved for Mountain Mode will be displayed on the battery
gauge, but will not be depleted until
it is required for uphill driving.
Press the MODE switch again to
return to Tour Mode and it becomes
active after three seconds.
Each time the vehicle is started, it
will return to Tour Mode to maintain
a smaller battery charge reserve for
normal driving.
Hold Mode
Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting thismode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.
Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Press the MODE switch and scroll
to Hold Mode to select it.
Press the MODE switch again to
return to Tour Mode and it becomes
active after three seconds.
Each time the vehicle is started, it
will return to Tour Mode.

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 may stop running
after the self test is completed
based on the current mode of
operation. SeeFuel System

Service Vehicle Messages on
page 5-49.
Maintenance Modes
Engine Maintenance Mode (EMM)
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 Start Maintenance is selected,
EMM will begin. The engine will run
for a set amount of time without
turning off. During EMM, a DIC
message displays to show the
EMM percentage complete.
If Postpone is selected, the EMM
Request screen will appear when
the vehicle is next started. The
EMM request can be delayed for
only one day.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start. An EMM Notification screen
will appear in the center stack
display.
If the vehicle shuts off during EMM,
it will restart the next time the
vehicle is driven. A message
displays to indicate that EMM is
active.
If EMM is required and the fuel level
is low, EMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. See
Propulsion Power
Messages on page 5-48.

Fuel Maintenance Mode (FMM)
FMM tracks average fuel age. Old
fuel can cause engine problems.
If low engine usage causes average
fuel age to exceed approximately
one year, FMM will run the engine to
use up the old fuel. The engine will
run until enough fresh fuel is added
to bring the average fuel age into an
acceptable range. Allowing more old
fuel to be used up by FMM and
adding a larger amount of fresh fuel
will maximize the length of time
before another FMM is needed.
During FMM the engine may turn on
and off.When FMM is needed, the FMM
Request screen appears on the
center stack display at vehicle start.
If Start Maintenance is selected,
FMM will begin. FMM will
automatically continue at each
vehicle start until fresh fuel is
added.
If Postpone is selected, the FMM
Request screen will appear when
the vehicle is next started. The FMM
request can be delayed for only
one day.
If the FMM request was delayed for
one day, FMM will start at the next
vehicle start and display the FMM
Notification screen on the center
stack display.If FMM is required and the fuel level
is low, FMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. See

Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The engine is running in
Extended Range Mode in
areas with poor ventilation
(parking garages, tunnels,
or deep snow that may block
underbody airflow or tail
pipes).
.The exhaust smells or
sounds strange or different.
.The exhaust system leaks
due to corrosion or damage.
.The vehicle exhaust system
has been modified, damaged,
or improperly repaired.(Continued)
Warning (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park with the engine
running in Extended Range Mode
in an enclosed area such as a
garage or a building that has no
fresh air ventilation.
Running the Vehicle
While Parked
It is better not to park with the
propulsion system running.
If the vehicle is left with the
propulsion system running, follow
the proper steps to be sure the
vehicle will not move. See Shifting

Driver Mode Control
Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assist in very
hilly or mountainous terrain. This
system simultaneously changes the
software calibration of various
sub-systems. Depending on the
option package, available features,
and mode selected, the suspension,
steering, and powertrain will change
calibrations to achieve the desired
mode characteristics. The vehicle is
equipped with Continuous Damping
Control (CDC). Selecting the various
Driver Modes adjusts the ride of the
vehicle to enhance the ride
performance for the road conditions
and the selected mode.
Driver Mode Control Switch
The Driver Mode Control has four
modes: Tour, Sport, Mountain, and
Hold. Press
zon the MODE switch
on the center console to make a
mode selection. The first press of
the switch will always show the Tour
Mode. Subsequent presses will
scroll though the available modes.
The Tour and Sport Modes will feel
similar on a smooth road. Select a
new setting whenever driving
conditions change. For additional information on these Modes, see
Driver Selected Operating Modes on
page 9-22.
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft
ride. Each time the vehicle is
started, it will return to Tour Mode.
Sport Mode
Use where road conditions or
personal preference demand a more
controlled response.
When selected, the Sport Mode
indicator will display in the DIC.
When in Sport Mode, the vehicle will
still shift automatically. The electric
drive unit may remain in gear longer
than it would in the normal driving
mode based on braking, throttle
input, and vehicle lateral
acceleration. The steering will
change to provide more precise
control. The suspension will change
to provide better body control and
handling performance.

9-36 Driving and Operating
Mountain Mode
Use when driving in very hilly or
mountainous terrain.
When selected, the Mountain Mode
indicator will display in the DIC.
This feature is intended to maintain
a reserve electrical charge of the
high voltage battery to provide
better grade climbing performance.
While driving in Mountain Mode, the
vehicle will have less responsive
acceleration.
Hold Mode
The Hold Mode is only available
when the vehicle is in the Electric
Mode. Use when wanting to change
to Extended Range Mode to
maintain the battery charge reserve.
SeeExtended Range Mode on
page 9-22.
When selected, the Hold Mode
indicator will display in the DIC.
This feature is intended to place the
remaining battery charge into a
reserve for the driver to use as desired. Hold Mode will not change
normal vehicle acceleration or
braking performance.
Continuous Damping
Control (CDC)
The CDC feature provides superior
vehicle ride and handling under a
variety of passenger and loading
conditions.
The system is fully automatic and
uses a computer controller to
continuously monitor vehicle speed,
wheel to body position, lift/dive, and
steering position of the vehicle. The
controller then sends signals to
each shock absorber to
independently adjust the damping
level to provide the optimum
vehicle ride.
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use the
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise
control disengages.

Driving and Operating 9-39
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. Also, you may have
to brake or shift to a lower gear to
keep the vehicle speed down. If the
brake is applied, the cruise control
disengages.
Ending Cruise Control
To disengage cruise control, do one
of the following:
.Step lightly on the brake pedal.
.Press*.
.PressJ.
.Press a Regen on Demand
paddle.Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses a radar
sensor. See Radio Frequency
Statement on page 13-15.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle speed when the Traction Control
System (TCS) activates, the ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control on page 9-33. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
StabiliTrak electronic stability control
system is disabled.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see
“Alerting the Driver” in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving on page 9-5.
