GETTING TO KNOW YOUR INSTRUMENT PANEL71

As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the low
tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them
to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can
lead to tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator
is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate
tires or wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS to
continue to function properly.

Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a
failure with the tow hook. Contact an
authorized dealer for service.
Transmission Temperature Warning Light
This warning light will illuminate to warn
of a high transmission fluid temperature.
This may occur with strenuous usage
such as trailer towing. If this light turns
on, stop the vehicle and run the engine at idle or
slightly faster, with the transmission in PARK (P) or
NEUTRAL (N), until the light turns off. Once the light
turns off, you may continue to drive normally.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have
your sensor function checked.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

84STARTING AND OPERATING
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.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), select
TOW/HAUL mode or use the Electronic Range
Select (ERS) shift control to select a lower gear
range Úpage 85. Under these conditions, using a
lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.

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. During extremely cold temperatures (-16°F [-27°C] or below), operation may
briefly be limited to THIRD gear only. Normal operation
will resume once the transmission temperature has
risen to a suitable level.

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 remains in THIRD gear regardless of
which forward gear is selected. PARK, REVERSE, and
NEUTRAL will continue to operate. The Malfunction
Indicator Light (MIL) may be illuminated. Transmission
Limp Home Mode allows 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.
3. Turn the ignition OFF.
4. Wait approximately 10 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.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must turn the ignition to the
ON/RUN position, 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!
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 130.
For Towing A Disabled Vehicle Ú page 219.

23_VF_OM_EN_USC_t.book Page 84

STARTING AND OPERATING85
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.
Electronic Range Select (ERS) Operation

The ERS shift control allows the driver to select the max
gear limit. For example, if you set the transmission gear
limit to FOURTH gear, the transmission will not shift
above FOURTH gear, but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Moving the gear
selector to the ERS position (beside DRIVE) will activate
ERS mode, display the current gear in the instrument
cluster, and set that gear as the max gear limit. Once in
ERS mode, moving the gear selector forward “-” or
rearward “+” will change the max gear limit.

NOTE:The transmission will still continue to use the
optimal highest gear, for the current driving condi -
tions, within the selected gear range limit.
To exit ERS mode, simply return the gear selector
to the DRIVE position.
NOTE:To select the proper gear position for maximum
deceleration (engine braking), move the gear
selector into the ERS position, then tap it forward
“-” repeatedly as the vehicle slows. The trans -
mission will shift to the range from which the
vehicle can best be slowed down.
When To Use TOW/HAUL Mode

When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting
occurs, push the TOW/HAUL switch to activate
TOW/HAUL mode. This will improve performance and
reduce the potential for transmission overheating or
failure due to excessive shifting. When operating in
TOW/HAUL mode, transmission upshifts are delayed,
and the transmission will automatically downshift
(for engine braking) during steady braking maneuvers.

The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL
mode has been activated. Pushing the switch a
second time restores normal operation. Normal operation is always the default at engine start-up.
If TOW/HAUL mode is desired, the switch must be
pushed each time the engine is started.
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 flashing, it indicates that the
vehicle needs to be taken to the dealer for service.
It is likely the vehicle has lost power steering
assistance.
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 56.
If the steering icon is displayed and the
“SERVICE POWER STEERING – ASSIST OFF”
message is displayed on the instrument cluster
screen, this indicates the vehicle needs to be
taken to the dealer for service Ú page 56.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

90STARTING AND OPERATING
(Continued)
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel
operate the ACC system.
Adaptive Cruise Control Buttons (If Equipped)
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).

Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.

Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
You should not utilize the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.

23_VF_OM_EN_USC_t.book Page 90

96STARTING AND OPERATING
NOTE:
If the “ACC Front Radar Sensor Temporarily
Blinded” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snowplow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC operation.
“ACC LIMITED FUNCTIONALITY CAMERA
BLOCKED” WARNING
The “ACC Limited Functionality Camera Blocked”
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 and fog on the inside of glass. In these
cases, the instrument cluster display will read
“ACC Limited Functionality Camera Blocked” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC
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 Limited Functionality Camera Blocked”
message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstruction, have the windshield and forward
facing camera inspected at an authorized dealer.
SERVICE ACC WARNING

If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required” or
“Cruise 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.

23_VF_OM_EN_USC_t.book Page 96

STARTING AND OPERATING105
When the gear selector shifted to NEUTRAL or
PARK, the system becomes inactive. When the
vehicle is moving forward, the system will remain
active until the vehicle speed remains below
approximately 11 mph (18 km/h). Reducing the
speed approximately below 9 mph (15 km/h), the
system will come back active. When the vehicle is
moving in REVERSE, the system will remain active
as long as the speed remains below the maximum
operating speed of 7 mph (11 km/h). When the
maximum speed limit is exceeded, the system is
disabled and the ParkSense switch LED will
illuminate. The system will become active again if
the vehicle speed reduces below approximately
6 mph (9 km/h).
Interaction With Trailer Towing
The Park Assist system is automatically
deactivated when a trailer is hitched to the vehicle.
The system will be automatically activated as soon
as the trailer is removed.
PARKSENSE SENSORS

The six ParkSense sensors (four when vehicle is
not equipped with front sensors), located in the rear
fascia/bumper, and the six ParkSense sensors located
in the front fascia/bumper, monitor the area in front
and behind the vehicle that is within the sensors’ field
of view. The front sensors detect obstacles from
approximately 12 inches (30 cm) up to 39 inches (100 cm) from the front fascia/bumper. The rear
sensors can detect obstacles from approximately
12 inches (30 cm) up to 55 inches (140 cm) from the
center of the rear fascia/bumper and up to 24 inches
(60 cm) from the corners of the rear fascia/bumper.
These distances depend on the location, type and
orientation of the obstacle in the horizontal direction.

Rear Park Assist Sensors Location

If several obstacles are detected, the ParkSense
system indicates the nearest obstacle.
The minimum height of a detectable obstacle
corresponds to the maximum height of an obstacle
that would clear the underside of the vehicle
during the parking maneuver.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be
displayed if “Sound and Display” is selected in the
Uconnect system Ú page 134.
The ParkSense Warning screen is located within
the instrument cluster display Ú page 56. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left and/or right front or
rear regions based on the object’s distance and
location relative to the vehicle.
If an object is detected in the left and/or right rear
region, the display will show a single arc in the
left and/or right rear region and the system will
produce a tone. As the vehicle moves closer to the
object, the display will show the single arc moving
closer to the vehicle and the tone will change from
a single 1/2 second tone to slow, to fast, to
continuous.
