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.

Highlight either the Mountain, Sport,
or Hold Mode, then release the
MODE switch. After three seconds,
the new drive mode will become
active.
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
Propulsion Power Messages on
page 5-48.
Sport Mode
Sport Mode provides more
responsive acceleration, steering,
and suspension than Tour Mode,
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.

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 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

Light on page 5-21. There are also
parking brake-related Driver
Information Center (DIC) messages.
SeeBrake System Messages on
page 5-41. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See
Electric
Parking Brake Light on page 5-20.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on,
see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system. If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/
ACCESSORY or ON/RUN
position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.

Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, the system brakes the
spinning wheel(s) and/or reduces
engine power to limit wheel spin.
StabiliTrak activates when the
computer senses a difference
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the intended direction. If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but It may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck on
page 9-11 and“Turning the Systems
Off and On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak is
activated.
.Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
