88STARTING AND OPERATING
Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY WARNING
The “ACC 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 display
the above message and the system will deactivate.
This 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 Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control can
be still enabled.
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 malfunc -
tion 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 after -
market 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 Unavailable Wipe Front Radar
Sensor” 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 snow plow, 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.
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.

22_VF_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
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.

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.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.

PARKSENSE PARK ASSIST FAILURE
I
NDICATIONS
A malfunction of the ParkSense Park Assist
sensors or system is indicated, during REVERSE
gear engagement, by the instrument panel
warning icon.
The warning icon is illuminated and a
message is displayed in the instrument
cluster display (if equipped) Ú page 59.
The sensors and wiring are tested continuously
when the ignition is in the ON/RUN position.
Failures are indicated immediately if they occur
when the system is on.
Even if the system is able to identify that a specific
sensor is in failure condition, the instrument
cluster display shall indicate that the ParkSense
Park Assist system is unavailable, without
reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be
disabled. The system is turned off automatically.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE PARK ASSIST SYSTEM
U
SAGE PRECAUTIONS
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument
cluster display will read “PARKSENSE OFF.”
Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you
cycle the ignition key.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.

Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud,
dirt or debris. Failure to do so can result in the
system not working properly. The ParkSense system might not detect an obstacle behind or in
front of the fascia/bumper, or it could provide a
false indication that an obstacle is behind or in
front of the fascia/bumper.

Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers,
etc. are placed within 12 inches (30 cm) from
the rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
NOTE:If any objects are attached to the bumper within a
6.5 ft (2 m) field of view, they will interfere and
cause false alerts and possibly blockage.
There may be a delay in the object detection
rate if the object is moving.
The operation of the rear sensors is automati
-
cally deactivated when the trailer's electric plug
is inserted in the vehicle's tow hook socket,
while the front sensors stay active and can
provide acoustic and visual warnings. The rear
sensors are automatically reactivated when the
trailer's cable plug is removed.

110STARTING AND OPERATING
RIM SIZE
This is the rim size that is appropriate for the tire
size listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full Gross
Axle Weight Rating (GAWR).
CURB WEIGHT
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with
no occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
OVERLOADING
The load carrying components (axle, springs,
tires, wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not exceed
the Gross Vehicle Weight Rating (GVWR) and the
front and rear Gross Axle Weight Rating (GAWR).
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and
ready for operation. Weigh it on a commercial scale
to ensure that it is not over the GVWR. Figure out the weight on the front and rear axle of
the vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles.
Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
LOADING
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side. Store
heavier items down low and be sure you distribute
their weight as evenly as possible. Stow all loose
items securely before driving. If weighing the
loaded vehicle shows that you have exceeded
either Gross Axle Weight Rating (GAWR), but the
total load is within the specified Gross Vehicle
Weight Rating (GVWR), you must redistribute the
weight. Improper weight distribution can have an
adverse effect on the way your vehicle steers and
handles and the way the brakes operate.
NOTE:Refer to the Vehicle Certification Label affixed to
the rear of the driver's door for your vehicle's GVWR
and GAWRs.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú
page 109.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.

144SAFETY

Overtaking/Passing

The BSM system is designed not to issue an alert
on stationary objects such as guardrails, posts,
walls, foliage, berms, snow banks, car washes, etc.
However, occasionally the system may alert on
such objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects that
are traveling in the opposite direction of the vehicle
in adjacent lanes Ú page 256.
Opposing Traffic

Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic, and if an
oncoming vehicle is detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 3 mph (5 km/h), to objects
moving a maximum of approximately 20 mph
(32 km/h), such as in parking lot situations.
WARNING!
The Blind Spot Monitoring system is only an aid
to help detect objects in the blind spot zones.
The BSM system is not designed to detect
pedestrians, bicyclists, or animals. Even if your
vehicle is equipped with the BSM system, always
check your vehicle’s mirrors, glance over your
shoulder, and use your turn signal before
changing lanes. Failure to do so can result in
serious injury or death.

150SAFETY
FCW Limited Warning
If the instrument cluster displays “FCW Limited
Functionality” or “FCW Limited Functionality Clean
Front Windshield” momentarily, there may be a
condition that limits FCW functionality. Although
the vehicle is still drivable under normal
conditions, the active braking may not be fully
available. Once the condition that limited the
system performance is no longer present, the
system will return to its full performance state.
If the problem persists, see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
displays: “FCW Unavailable Service Required”,
this indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
“FCW Temporarily Unavailable” Warning
The “FCW Temporarily Unavailable” warning will be
displayed when conditions temporarily deactivate
the system. This most often occurs at times of poor
visibility, such as in snow or heavy rain. The system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will show
“FCW Temporarily Unavailable” and the system will
deactivate. The “FCW Temporarily Unavailable” message can
sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The 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 fascia/bumper where
the camera is located. It may require cleaning or
removal of an obstruction from the fascia/bumper
cover.NOTE:
If the “FCW Temporarily Unavailable” message
occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other
obstruction, have the camera realigned at an
authorized dealer.
Installing a snow plow or front-end protector is
not recommended. Doing so may block the
camera and inhibit FCW operation.
Use only a soft cloth for cleaning. Do not use
solvents or abrasive pastes.
Precautions While Driving With FCW
In certain driving conditions, such as:
Driving in the vicinity of a curve
Small vehicles and/or not aligned to the lane
Lane changing of other vehicles
Passing of vehicles in an oncoming intersection
The intervention of the system could be
unexpected or delayed. The driver must therefore
always pay particular attention, while maintaining
control of the vehicle to drive in complete safety.
Driving In The Vicinity Of A Curve
Entering or exiting a large curve, the system could
detect the presence of a vehicle that is in front of
the vehicle, but that does not preside in the same
lane. In cases such as this, the system might
respond.
