STARTING AND OPERATING69
TO ACCELERATE FOR PASSING
While the Cruise Control system is set, press the
accelerator to pass as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up
and down hills. A slight speed change on
moderate hills is normal. On steep hills, a
greater speed loss or gain may occur so it may
be preferable to drive without Cruise Control.
TO RESUME SPEED
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
TO DEACTIVATE
A soft tap on the brake pedal, pushing the RES
button, or normal brake pressure while slowing
the vehicle will deactivate Cruise Control
without erasing the set speed memory. Rotating
the center ring upward to turn the system off or
placing the ignition in the STOP (OFF/LOCK)
position erases the set speed memory.
PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system
provides an audible indication of the distance
between the rear fascia/bumper and a
detected obstacle when backing up (e.g. during
a parking maneuver) Úpage 72.
The ParkSense Rear Park Assist is
automatically activated when the transmission
is placed into REVERSE. As the distance from an
obstacle behind the vehicle decreases, the
audible alert becomes more frequent.
Interaction With Trailer Towing
The Rear 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.
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.

PARKSENSE REAR PARK ASSIST
S
ENSORS
The four ParkSense Rear Park Assist sensors,
located in the rear fascia/bumper, monitor the
area behind the vehicle that is within the
sensors’ field of view. The sensors can detect
obstacles, in the horizontal direction, 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,
depending on the location, type and orientation
of the obstacle.
Rear Park Assist Sensors Location

If several obstacles are detected, the
ParkSense Rear Park Assist 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 REAR PARK ASSIST
A
LERTS
If an obstacle is behind the vehicle when
REVERSE gear is engaged, an audible alert is
activated.
The tones emitted by the loudspeaker inform
the driver that the vehicle is approaching an
obstacle. The pauses between the tones are
directly proportional to the distance from the
obstacle. Pulses emitted in quick succession
indicate the presence of a very close obstacle.
A continuous tone indicates that the obstacle is
less than 12 inches (30 cm) away.

21_VF_OM_EN_USC_t.book Page 70

STARTING AND OPERATING71
While audible signals are emitted, the audio system is not muted.
The audible signal is turned off immediately if the distance increases. The tone cycle remains constant if the distance measured by the inner sensors
is constant. If this condition occurs for the external sensors, the signal is turned off after three seconds (stopping warnings during maneuvers parallel
to walls).

AILURE INDICATIONS
A malfunction of the ParkSense Rear 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 48.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/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 Rear 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 Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors.

S
YSTEM USAGE PRECAUTIONS
NOTE:
Ensure that the outer surface and the under -
side of the rear fascia/bumper is clean and
clear of snow, ice, mud, dirt or other obstruc -
tion to keep the Rear Park Assist system
operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Rear
Park Assist.
Clean the Rear Park Assist 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 prop -erly. The Rear Park Assist system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indication
that an obstacle is behind the fascia/
bumper.
Objects such as bicycle carriers, etc., must
not be placed within 12 inches (30 cm) from
the rear fascia/bumper while driving the
vehicle. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing a failure indication
to be displayed in the instrument cluster
display.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.

21_VF_OM_EN_USC_t.book Page 72

STARTING AND OPERATING73
(Continued)
If it’s necessary to keep the ball mount and
hitch ball assembly mounted for a long period,
it is possible to filter out the ball mount and
hitch ball assembly presence in the sensor field
of view. The filtering operation must be
performed only by an authorized dealer.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear
Back Up Camera that allows you to see an
on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put
into REVERSE and/or when the rear doors are
opened. The image will be displayed on the
touchscreen display along with a caution note to “Check Entire Surroundings” across the top
of the screen. After five seconds this note will
disappear. The ParkView Rear Back Up Camera
is located on the top rear of the vehicle below
the center light.

Rear Back Up Camera Location

When the vehicle is shifted out of REVERSE
and/or when the rear doors are closed, the rear
camera mode is exited and the previous screen
appears.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the loudspeaker sounds the continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica -
tion that an obstacle is behind the vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above or
below the sensors will not be detected
when they are in close proximity.
WARNING! (Continued)
The vehicle must be driven slowly when
using ParkSense in order to be able to stop
in time when an obstacle is detected. It is
recommended that the driver looks over
his/her shoulder when using ParkSense.
CAUTION! (Continued)

Red 0 - 1 ft (0 - 30 cm)
Yellow 1 ft - 3 ft (30 cm - 1 m)
Green 3 ft or greater (1 m or greater)
WARNING!
Drivers must be careful when backing up
even when using the Rear Back Up Camera.
Always check carefully behind your vehicle,
and be sure to check for pedestrians,
animals, other vehicles, obstructions, or blind
spots before backing up. You are responsible
for the safety of your surroundings and must
continue to pay attention while backing up.
Failure to do so can result in serious injury or
death.
CAUTION!
To avoid vehicle damage, ParkView should
only be used as a parking aid. The ParkView
camera is unable to view every obstacle or
object in your drive path.
To avoid vehicle damage, the vehicle must
be driven slowly when using ParkView to be
able to stop in time when an obstacle is
seen. It is recommended that the driver
look frequently over his/her shoulder when
using ParkView.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door
on the left side of the vehicle. If the gas cap is
lost or damaged, be sure the replacement cap
is used with this vehicle.
Fuel Filler

NOTE:
During fuel fill, nozzle position could affect the
flow of fuel. For best results, allow the nozzle to
rest naturally in the filler tube - do not raise the
handle to increase the fill angle. NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
If the gas cap is not tightened properly, the
MIL may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu
-
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.
CAUTION! (Continued)

LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a “Check fuel cap” message will be
displayed in the instrument cluster display
Úpage 44. Tighten the fuel filler cap until a
“clicking” sound is heard. This is an indication
that the fuel filler cap is properly tightened.
If the problem continues, the message will
appear the next time the vehicle is started. See
an authorized dealer as soon as possible.
VEHICLE LOADING
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side
door or B-pillar.
If seats are removed for carrying cargo, do not
exceed the specified GVWR and GAWR.
VEHICLE CERTIFICATION LABEL
Your vehicle has a Vehicle Certification Label
affixed to the driver’s side B-pillar or the rear of
the driver’s door.
The label contains the following information:
Name of manufacturer
Month and year of manufacture
Gross Vehicle Weight Rating (GVWR)
Gross Axle Weight Rating (GAWR) front and
rear
Vehicle Identification Number (VIN)
Type of vehicle
Month, Day, and Hour of manufacture (MDH)
The bar code allows a computer scanner to read
the VIN.
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, and
cargo. The total load must be limited so that you
do not exceed the GVWR.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it
is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have a collision.

21_VF_OM_EN_USC_t.book Page 76

STARTING AND OPERATING77
TIRE SIZE
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
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.

78STARTING AND OPERATING
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
Úpage 76.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in
combination.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and
equipment (permanent or temporary) loaded in
or on the trailer in its “loaded and ready for
operation” condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be
supported by the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR
Úpage 76.
Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. You must consider this
as part of the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height
multiplied by the maximum width of the front of
a trailer.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have a collision.
