9-28 Driving and Operating
Electric Drive Unit
The vehicle uses an electric
drive unit.
P (Park):This position locks the
front wheels. It is the best position
to use when starting the propulsion
system because the vehicle cannot
move easily.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
propulsion system is running.
If you have left the propulsion
system running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park on
page 9-19.
Make sure the shift lever is fully in
P (Park) before starting the
propulsion system. The vehicle has
an electric drive unit shift lock
control system. The regular brake
must be fully applied first and then
the shift lever button pressed before shifting from P (Park) when the
vehicle is in ON/RUN. If you cannot
shift out of P (Park), ease pressure
on the shift lever, then push the shift
lever all the way into P (Park) as
you maintain brake application.
Then press the shift lever button
and move the shift lever into
another gear. See
Shifting out of
Park on page 9-20.
R (Reverse): Use this gear to
back up.
{Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the electric drive unit.
The repairs would not be covered
by the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the electric drive unit, see
If the Vehicle Is Stuck on page 9-12.

Driving and Operating 9-29
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.
{Caution
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.
The brake lamps may come on
when the vehicle is in L (Low) and
the accelerator is not pressed to
indicate the vehicle is slowing down.
{Caution
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 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.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5-21.

9-30 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehiclesuddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch is to the
left of the steering wheel. 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.

Driving and Operating 9-31
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light on page 5-21
and Service Electric Parking Brake
Light on page 5-21. There are also
parking brake-related Driver
Information Center (DIC) messages.
See Brake System Messages on
page 5-42. 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 5-21.
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.

9-32 Driving and Operating
{Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency.The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. The controller
interprets the braking request and
uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor-driven
pump when it recharges the system.
This is normal.
See
Warning Lights, Gauges, and
Indicators on page 5-7 andDriver
Information Center (DIC) on
page 5-38. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Regen on Demand™
Regen on Demand allows increased
deceleration by pressing and
holding either of the steering wheel
paddle switches. It works in
D (Drive) and L (Low). The
accelerator pedal must be fully
released for it to work.
The brake pedal must be applied at
low speed, because it will not stop
the car.
Cruise control will turn off, and the
brake lights may come on, when
this feature is activated.

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 9-12 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.

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.
