There are several different positions
for the shift lever.
P :This position locks the drive
wheels. Use P (Park) when starting the
engine 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.

Warning (Continued)
Do not leave the vehicle when the
engine is running unless you have
to. If you have left the engine
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). SeeShifting Into
Park 0224. If you are pulling a
trailer, see Driving Characteristics
and Towing Tips 0290.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an electronic shift
lock release system. Fully apply the
regular brakes first and then press the
shift lever button before shifting from
P (Park) when the ignition is on. If you
cannot shift out of P (Park), ease
pressure on the shift lever and 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 0225.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by the
vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped.
R : Use this gear to back up.
At low vehicle speeds, R (Reverse) can
be used to rock the vehicle back and
forth to get out of snow, ice, or sand
without damaging the transmission.
See If the Vehicle Is Stuck 0212.
N : In this position, the engine does
not connect with the wheels. To
restart the engine when the vehicle is
already moving, use N (Neutral) only.

234 DRIVING AND OPERATING
If shifting is prevented for any reason,
a SHIFT DENIED message will be
displayed in the instrument cluster.
When accelerating the vehicle from a
stop in snowy and icy conditions, it is
suggested to shift into second gear.
A higher gear allows the vehicle to
gain more traction on slippery
surfaces.Drive Systems
All-Wheel Drive
Vehicles with this feature always send
engine power to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced electronic
braking system that helps prevent a
braking skid.
When the vehicle begins to drive
away, ABS checks itself. A momentary
motor or clicking noise may be heard
while this test is going on, and it may
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. SeeAntilock
Brake System (ABS) Warning Light
0 146.
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to avoid

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
Yor PARK light is
flashing. See your dealer. See Electric
Parking Brake Light 0145.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Yor PARK light
remains on. If the
8light remains on,
see your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is pressed. If the
switch is pressed 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, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Yor
PARK light is off.
If the
8light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until
the
Yor PARK light is off. If either
light stays on after release is
attempted, see your dealer.
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.
Brake Assist
This vehicle has a brake assist feature
designed to assist the driver in
stopping or decreasing vehicle speed
in emergency driving conditions. This
feature uses the stability system
hydraulic brake control module to
supplement the power brake system
under conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the vehicle
until the ABS activates. Minor brake
pedal pulsation or pedal movement
during this time is normal and the
driver should continue to apply the
brake pedal as the driving situation
dictates. The brake assist feature will

Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
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 for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. See Radio Frequency
Statement 0417. The following gap is
the following time (or distance)
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.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak electronic stability control
system activates while ACC is
engaged, ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0239. When
road conditions allow ACC to be safely
used, 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 0207.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.

250 DRIVING AND OPERATING
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
you will need to manually apply the
brakes to slow the vehicle when:
. The sensors are blocked. .
The Traction Control System (TCS)
or electronic stability control
system has activated or been
disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system.
The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC will not
activate, regular Cruise Control may
be used. See “Switching Between ACC
and Regular Cruise Control ”previously
in this section. Always consider
driving conditions before using either
cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three times, or three beeps will sound.
See
”Alert Type ”and “Adaptive Cruise
Go Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 170.
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver seat belt is unbuckled, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn
on. See Electric Parking Brake 0235.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0169.

Parking Assist
With RPA, and if equipped with FPA,
as the vehicle moves at speeds of less
than 8 km/h (5 mph) the sensors on
the bumpers may detect objects up to
2.5 m (8 ft) behind and 1.2 m (4 ft) in
front of the vehicle within a zone
25 cm (10 in) high off the ground and
below bumper level. These detection
distances may be shorter during
warmer or humid weather. Blocked
sensors will not detect objects and
can also cause false detections. Keep
the sensors clean of mud, dirt, snow,
ice, and slush; and clean sensors after
a car wash in freezing temperatures.
{Warning
The Parking Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with Parking Assist,(Continued)
Warning (Continued)
always check the area around the
vehicle and check all mirrors before
moving forward or backing.
The instrument cluster may have a
parking assist display with bars that
show“distance to object ”and object
location information for the Parking
Assist system. As the object gets
closer, more bars light up and the bars
change color from yellow to amber
to red.
When an object is first detected in the
rear, one beep will be heard from the
rear, or both sides of the Safety Alert
Seat will pulse two times. When an
object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the
vehicle front), five beeps will sound
from the front or rear depending on
object location, or both sides of the
Safety Alert Seat will pulse five times.
Beeps for FPA are higher pitched than
for RPA.
Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. The Backing
Warning part of this system can warn
of rear objects when backing up at
speeds greater than 8 km/h (5 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.

To switch the parking mode between
parallel and perpendicular, touch and
hold
Oduring the search process or,
if available, change the parking mode
in the infotainment display.
After completely passing a large
enough space, an audible beep occurs.
A red stop symbol and a shift to
reverse message are displayed.
If the vehicle is in R (Reverse), but
does not steer into the expected
space, this may be because the system
is maneuvering the vehicle into a
previously detected space. The APA
system does not need service.
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the displayed instructions.
Shift to R (Reverse) to engage
automatic steering. The steering wheel
will vibrate briefly as a reminder to
remove hands from the steering
wheel. APA uses idle speed and
braking to park. If idle speed is not
sufficient, gently press the accelerator.
Check surroundings and be prepared
to stop to avoid vehicles, pedestrians,
or objects not detected by the system.
In case the driver brakes, APA will not
disengage. Manual steering by the
driver automatically disengages APA.
Vehicle speed is limited to a
maximum of 5 km/h (3 mph) during
the parking maneuver. A progress arrow displays the status
of the parking maneuver. Depending
on the space size, additional
maneuvers may be required, and there
will be additional instructions. When
changing gears, allow the automatic
steering to complete before continuing
the parking maneuver. APA will beep
and display a PARKING COMPLETE
message. Apply the brakes and place
the vehicle in P (Park).
APA may automatically disengage if:
.
The steering wheel is used by the
driver.
. The maximum allowed speed is
exceeded.
. There is a failure with the APA
system.
. Electronic stability control or
antilock brakes are activated.
. A high priority vehicle message is
displayed in the DIC.
. The driver opens the door with an
unbuckled seat belt.
To cancel APA, touch
