ENGINE START/STOP B
UTTON

1. Place the gear selector in PARK, then push
and release the ENGINE START/STOP button.

2. The ignition switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/STOP button must be held for two
seconds or three short pushes in a row with
the vehicle speed above 5 mph (8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position
until the gear selector is in PARK and the
button is pushed twice to the OFF position. If
the gear selector is not in PARK and the
ENGINE START/STOP button is pushed once,
the instrument cluster will display a “Vehicle
Not In Park” message and the engine will
remain running. Never leave a vehicle out of
the PARK position, or it could roll.
NOTE:If the ignition switch is left in the ACC or ON/RUN
(engine not running) position and the transmission
is in PARK, the system will automatically time out
after 30 minutes of inactivity and the ignition will
switch to the OFF position.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and
permits quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
For ambient temperatures below 0°F (-18°C), the
engine block heater is recommended. For ambient
temperatures below -20°F (-29°C), the engine
block heater is required.
The engine block heater cord is routed under the
hood, behind to the passenger’s side headlamp.
Follow the steps below to properly use the engine
block heater:

1. Locate the engine block heater cord (behind the passenger’s side headlamp).

2. Undo the hook-and-loop strap that secures the heater cord in place.
3. Pull the cord to the front of the vehicle and plug it into a grounded, three-wire extension
cord.
4. After the vehicle is running, reattach the cord to the hook-and-loop strap and properly stow
away behind the passenger’s side headlamp.
NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not equipped,
heater cords are available from an authorized
dealer.
The engine block heater will require 110 Volt AC
and 6.5 Amps to activate the heater element.
The engine block heater must be plugged in at
least one hour to have an adequate warming
effect on the engine.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

21_RUP_OM_EN_USC_t.book Page 136

STARTING AND OPERATING137
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades Ú page 333.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient and
useful. The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure that the parking
brake is applied. Also, be certain to leave the
transmission in PARK.
You can engage the parking brake in two ways;
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the customer programmable features
Ú
page 189.
The EPB is located in the integrated center stack.

Electric Park Brake Switch

To apply the parking brake manually, push the
switch momentarily. You may hear a sound from
the back of the vehicle while the parking brake
engages. Once the parking brake is fully engaged,
the BRAKE warning lamp in the instrument cluster
and an indicator on the switch will illuminate. If your foot is on the brake pedal while you apply
the parking brake, you may notice a small amount
of brake pedal movement. The parking brake can
be applied even when the ignition switch is OFF,
however, it can only be released when the ignition
switch in the ACC or ON/RUN position.
NOTE:The EPB fault lamp will illuminate if the EPB switch
is held for longer than 180 seconds. The light will
extinguish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage whenever
the transmission is placed into PARK. Once the
parking brake is engaged, the BRAKE warning
lamp in the instrument cluster and the LED
indicator on the switch will illuminate. If your foot is
on the brake pedal, you may notice a small amount
of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when
the ignition is cycled to the ON/RUN position, the
transmission is in DRIVE or REVERSE, and the
driver seat belt is buckled and an attempt is made
to drive the vehicle away by pressing the
accelerator pedal.
To release the parking brake manually, the ignition
switch must be in the ON/RUN position. Press on
the brake pedal, then push the parking brake
switch momentarily.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

(Continued)
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK before the ignition can be turned to the OFF
mode. This helps the driver avoid inadvertently
leaving the vehicle without placing the
transmission in PARK. This system also locks the
transmission in PARK whenever the ignition is in
the OFF mode.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC mode)
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 indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
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 mode, the transmission
is locked in PARK, securing the vehicle against
unwanted movement.
WARNING!
When exiting the vehicle, always make sure
the ignition is in the OFF mode, 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 chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ACC or ON/RUN
mode. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
WARNING!
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
CAUTION!

STARTING AND OPERATING141
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission out of
PARK, the engine must be running and the brake
pedal must be pressed. The brake pedal must also
be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at
low speeds.
9-SPEED AUTOMATIC TRANSMISSION
The transmission is controlled using a rotary
electronic gear selector located on the center
console. The transmission gear selector has PARK,
REVERSE, NEUTRAL, DRIVE, and LOW shift
positions. Using the LOW position manually
downshifts the transmission to a lower gear based
on vehicle speed. The transmission gear range
(PRNDL) is displayed both above the gear selector
and in the instrument cluster. To select a gear
range, simply rotate the gear selector. Push down
on the gear selector and then rotate it, to access
the L position. You must also press the brake pedal
to shift the transmission out of PARK (or NEUTRAL,
when stopped or moving at low speeds). To shift
past multiple gear ranges at once (such as PARK to
DRIVE), simply rotate the gear selector to the
appropriate detent. Select the DRIVE range for
normal driving.
NOTE:In the event of a mismatch between the gear
selector position and the actual transmission gear
(for example, driver selects PARK while driving),
the position indicator will blink continuously until
the selector is returned to the proper position, or
the requested shift can be completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions. The
transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle may
be somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles (kilometers).
The 9-speed transmission has been developed to
meet the needs of current and future FWD/AWD
vehicles. Software and calibration is refined to
optimize the customer’s driving experience and
fuel economy. By design, some vehicle and
driveline combinations utilize NINTH gear only in
very specific driving situations and conditions.
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
Transmission Gear Selector

GEAR RANGES
Do not press the accelerator pedal when shifting
from PARK or NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before acceler
-
ating. This is especially important when the engine
is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.

142STARTING AND OPERATING
(Continued)
(Continued)
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb
on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition off.
Remove the key fob from the vehicle.
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 transmission 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 indi
-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
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 mode, the transmission
is locked in PARK, securing the vehicle against
unwanted movement.
WARNING!
When exiting the vehicle, always make sure
the ignition is in the OFF mode, 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 chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ACC or ON/RUN
mode. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, and
also press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
WARNING!

21_RUP_OM_EN_USC_t.book Page 142

STARTING AND OPERATING143
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has come
to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into PARK
if you must exit the vehicle.
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 144. 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.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing
traffic or road conditions. You might lose control
of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in NEUTRAL
can cause severe transmission damage.
For Recreational Towing Ú page 185.
For Towing A Disabled Vehicle Ú page 324.

144STARTING AND OPERATING
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 pre-emptive effort to
improve vehicle launch and performance
characteristics.
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.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the power
transfer unit.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

21_RUP_OM_EN_USC_t.book Page 144

STARTING AND OPERATING145
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
Ú page 123.
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 the dealer for service.
It is likely the vehicle has lost power steering
assistance Ú page 123.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially 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 developed 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 Ú page 123.
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.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions for Stop/Start
and ensure they are fulfilled. Detailed information
about the operation of the Stop/Start system
may be viewed in the instrument cluster display
Stop/Start screen. Situations when the engine will
not stop include (but not limited to):
If Stop/Start is manually disabled by the
Stop/Start OFF button.
Driver’s seat belt is not buckled.
Driver’s door is not closed.
Battery temperature is too warm or cold.
Battery charge is low. During this time a
message will display “Stop/Start Not Ready
Battery Charging”.
The vehicle is on a steep grade.
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved.
