Brake Service Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Service Mode during brake
service.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the Electric Park Brake (EPB) system,
this can only be done after retracting the EPB actuator.
Fortunately, actuator retraction can be done easily by
entering Brake Service in your vehicle
Úpage 158. This
menu-based system will guide you through the steps
necessary to retract the EPB actuator in order to perform
rear brake service.
Brake Service has requirements that must be met in order
to be activated:
 The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK or NEUTRAL.
While in Brake Service, the EPB Warning Light will flash
continuously while the ignition switch is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
 Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the trans -
mission gear selector out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before exiting the vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.

 It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is firmly
pressing the brake pedal.

 Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle, and lock the vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
WARNING!

120STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteristics
under all normal operating conditions.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light will illuminate, a
warning message will appear in the instrument cluster,
and the transmission may operate differently until the
transmission cools down.

During cold temperatures, transmission operation may be
modified depending on engine and transmission temperature
as well as vehicle speed. This feature improves warm-up time
of the engine and transmission to achieve maximum efficiency.
Engagement of the torque converter clutch, and shifts into
EIGHTH or NINTH gear, are inhibited until the transmission fluid
is warm

Ú
page 120. Normal operation will resume once the
transmission temperature has risen to a suitable level.

LOW (L)
Use this range for engine braking when descending very
steep grades. In this range, the transmission will
downshift for increased engine braking. To access the
LOW position, push down on the gear selector and rotate
it fully clockwise.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer
service is required.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage until the
engine and/or transmission is warm (usually after 1 to
3 miles [2 to 5 km] of driving). Because the engine speed
is higher when the torque converter clutch is not engaged,
it may seem as if the transmission is not shifting properly
when the vehicle is cold. This is normal. The torque
converter clutch will function normally once the powertrain
is sufficiently warm.
ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This feature provides on-demand All-Wheel Drive (AWD).
The system is automatic with no driver inputs or additional
driving skills required. Under normal driving conditions,
the front wheels provide most of the traction. If the front
wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a preemptive effort to improve vehicle launch
and performance characteristics.

23_RUP_OM_EN_USC_t.book Page 120

STARTING AND OPERATING121
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancellation
system. This system is designed to address exhaust and
engine noise. The system relies on four microphones
embedded in the headliner, which monitor exhaust and
engine noise, and assists an onboard frequency
generator, which creates counteracting sound waves in
the audio system’s speakers. This helps keep the vehicle
quiet at idle and during drive.
POWER STEERING
The electric power steering system will provide increased
vehicle response and ease of maneuverability. The power
steering system adapts to different driving conditions. If the Steering icon is displayed and the “Power Steering
System Over Temp” message is displayed on the
instrument cluster screen, this indicates an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle
idle for a few moments until the icon and message turn off
Úpage 102.
If the “Service Power Steering" or "Power
Steering Assist Off - Service System” message
and a steering wheel icon are displayed on the
instrument cluster screen, it indicates that the
vehicle needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power steering
assistance
Úpage 102.
NOTE:
 Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 The power steering system is fully electric; it requires
no power steering fluid.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed to reduce fuel
consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal, pressing
the accelerator pedal or shifting out of DRIVE (D) will
automatically re-start the engine.
This vehicle has been upgraded with a heavy-duty starter,
enhanced battery, and other upgraded engine parts to
handle the additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every driver key
start. At that time, the system will go into STOP/START
READY and if all other conditions are met, can go into a
STOP/START AUTOSTOP ACTIVE.
To Activate Auto STOP/START, The Following Must Occur:
The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster within the Stop/Start section
Úpage 102.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained throughout the Auto Stop/Start process.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause premature wear of the driveline
components.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

will appear in the instrument cluster display
If the “Service STOP/START System” message appears in
the instrument cluster display, have the system checked
by an authorized dealer.
If a malfunction occurs during an autostop, the vehicle
may not auto start and will need a key start.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise Control
system, or the Adaptive Cruise Control (ACC) system:
 Cruise Control will keep your vehicle at a constant
preset speed.
 Adaptive Cruise Control (ACC) will adjust the vehicle
speed up to the preset speed to maintain a distance
with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not enabled,
Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected. 
Only one Cruise Control feature can operate at a time.
For example, if Fixed Speed Cruise Control is enabled,
Adaptive Cruise Control will be unavailable, and vice
versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over accelerator
operations at speeds greater than 20 mph (32 km/h).
The Cruise Control buttons are located on the right side of
the steering wheel.

Cruise Control Buttons

To Activate
Push the on/off button to activate the Cruise Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the on/off button
a second time. The cruise indicator light will turn off. The
system should be turned off when not in use.
To Set A Desired Speed
Turn the Cruise Control on.
NOTE:The vehicle should be traveling at a steady speed and on
level ground before pushing the SET (+) or SET (-) button.
When the vehicle has reached the desired speed, push

WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
WARNING!
Leaving the Cruise Control system on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always turn the system
off when you are not using it.

STARTING AND OPERATING129
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following the vehicle in front, your vehicle
will resume motion, without the need for any driver action,
if the vehicle in front starts moving within two seconds.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
set speed.
NOTE:After the ACC system holds your vehicle at a standstill for
approximately three consecutive minutes, the parking
brake will be activated, and the ACC system will be
canceled.
While the ACC system is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the driver
door is opened, the parking brake will be activated, and
the ACC system will be canceled.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR” WARNING
The “ACC/AEB Unavailable Wipe Front Radar Sensor”
warning will display and a chime will sound when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
show “ACC/AEB Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/AEB Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/AEB Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control is still
available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille. To keep the ACC System operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
 Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 If the sensor or front end of the vehicle is damaged due
to a collision, see an authorized dealer for service.
 Do not attach or install any accessories near the
sensor, including transparent material or aftermarket
grilles. Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:If the “ACC/AEB Unavailable Wipe Front Radar Sensor”
message occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other obstructions,
have the radar sensor realigned at an authorized dealer.WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

130STARTING AND OPERATING
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/AEB Limited Functionality Clean Front
Windshield” warning will display and a chime will sound
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions, such as
mud, dirt, or ice on windshield, driving directly into the sun
and fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/AEB Limited
Functionality Clean Front Windshield” and the system will
have degraded performance.
The “ACC/AEB Limited Functionality Clean Front
Windshield” message can sometimes be displayed while
driving in adverse weather conditions. The ACC/FCW
system will recover after the vehicle has left these areas.
Under rare conditions, when the camera is not tracking
any vehicles or objects in its path this warning may
temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rearview mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/AEB Limited Functionality Clean Front Wind -
shield” message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstructions, have the windshield and forward facing
camera inspected at an authorized dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/FCW
Unavailable Service Required”, there may be an internal
system fault or a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable. If
this occurs, try activating ACC again later, following an
ignition cycle. If the problem persists, see an authorized
dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or
unexpectedly. The driver needs to stay alert and may need
to intervene. The following are examples of these types of
situations:
TOWING A TRAILER
Towing a trailer is not recommended when using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may increase or decrease the vehicle speed for stability,
with no vehicle ahead detected. Once the vehicle is out of
the curve, the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
