9-6 Driving and Operating
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition
of the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts—heavy acceleration
followed by heavy braking —rather
than keeping pace with traffic.
This is a mistake. The brakes
might not have time to cool between
hard stops. The brakes will wear
out much faster with a lot of heavy braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If propulsion is disabled while
the vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If propulsion stops, there
will still be some power brake assist
but it will be used when the brake
is applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.Steering
Electric Power Steering
If propulsion is disabled, the power
steering assist system may continue
to operate until you are able to stop
the vehicle. If power steering assist
is lost because the electric power
steering system is not functioning,
the vehicle can be steered but it
will take more effort.
The electric power steering
system does not require regular
maintenance. If you suspect
steering system problems and/or
the SERVICE POWER STEERING
message comes on, contact your
dealer for service. See
Service
Vehicle Messages on page 5‑51.

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.

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 Vehicle
Operating Modes
System Operation
This vehicle is an Extended Range
Electric Vehicle (EREV). It uses an
electric propulsion system to drive
the vehicle at all times. Electricity
is the vehicle's primary source of
energy, while gasoline is the
secondary source.
The vehicle has two modes of
operation: Electric and Extended
Range. In both modes, the vehicle
is propelled by its electric drive unit.
It converts electrical energy into
mechanical energy to drive the
wheels. The vehicle's performance
remains the same in either mode.
See Driving for Better Energy
Efficiency on page 9‑2.

9-28 Driving and Operating
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.

N (Neutral):In this position, the
propulsion system does not connect
with the wheels.
D (Drive): This position is for
normal driving. It provides the
best fuel economy. If more power
is needed for passing, and the
vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph)
or more, push the accelerator
all the way down.
Notice: If the vehicle seems to
accelerate slowly or not respond
when you go faster, and you
continue to drive the vehicle
that way, you could damage
the electric drive unit. Have the
vehicle serviced right away. L (Low):
This position reduces
vehicle speed without using the
brakes. You can use L (Low) on
hills. It can help control vehicle
speed going down steep mountain
roads along with using the brakes
off and on. You can use L (Low)
on very steep hills, in deep snow,
or in mud.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the electric drive unit. The repair
will not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When propulsion is active and
the vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might be
heard while this test is going on,
and it might even be noticed that
the brake pedal moves a little.
This is normal.

Driving and Operating 9-35
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The
Yswitch is
on the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12‐volt battery, avoid repeated
cycles of the EPB system when
the vehicle is off.
In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the
Yswitch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE
will be displayed. The vehicle
will decelerate as long as the
switch is held in the up position. Releasing the
Yswitch during the
deceleration will release the parking
brake. If the
Yswitch is held in
the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING BRAKE will be displayed.
If this light flashes continuously,
release the EPB, and attempt to
apply it again. If this light continues
to flash, do not drive the vehicle.
See your dealer.
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality.
