Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is designed to
assist the driver when starting a vehicle from a stop
on a hill. HSA will maintain the level of brake pres -
sure the driver applied for a short period of time
after the driver takes their foot off of the brake
pedal. If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down the hill.
The system will release brake pressure in proportion
to the amount of throttle applied as the vehicle
starts to move in the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA
to activate:
Vehicle must be stopped
Vehicle must be on a 6% (approximate) grade or
greater hill
Gear selection matches vehicl e uphill direction
(i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE (R) gear)
HSA will work in REVERSE and all forward gears
when the activation criteria have been met. The
system will not activate if the vehicle is placed in
NEUTRAL (N) or PARK (P).

Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the
amount of wheel spin of each of the driven
wheels. If wheel spin is detected, brake pressure
is applied to the slipping wheel(s) and engine
power is reduced, to provide enhanced accelera -
tion and stability. A feature of the TCS system,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and controls
the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other,
the system will apply the brake of the spinning
wheel. This will allow more engine torque to be
applied to the wheel that is not spinning. This
feature remains active even if the ESC is in the
“Partial Off” mode.

WARNING!
There may be situations on minor hills with
a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight
rolling may occur. This could cause a
collision with another vehicle or object.
Always remember the driver is responsible
for braking the vehicle.
WARNING!
If you use a trailer brake controller with
your trailer, the trailer brakes may be acti -
vated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake
pedal is released. In order to avoid rolling
down an incline while resuming accelera -
tion, manually activate the trailer brake
or apply more vehicle brake pressure
prior to releasing the brake pedal.
HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.
WARNING!

The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
under-inflation has not reached the level to
trigger illumination of the TPMS Warning
Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
Base System
This is the TPMS warning indicator
located in the instrument cluster.
The TPMS uses wireless technology
with wheel rim mounted electronic
sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to
the Receiver Module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
regularly and to maintain the proper pressure.
The TPMS consists of the following components:

Receiver Module
Four Tire Pressure Monitoring sensors
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning
Light will illuminate in the instrument cluster, an
audible chime will be activated, and the “Check
tire pressure” message will display when one or
more of the four active road tire pressures are
low. Should this occur, you should stop as soon
as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to
the vehicle’s recommended cold placard pres
-
sure value. The system will automatically
update and the Tire Pressure Monitoring Light
will extinguish once the updated tire pressures
have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
remain on solid when a system fault is detected,
an audible chime will be activated and the “Tire
Pressure Monitoring Unavailable” message will
display. If the ignition key is cycled, this
sequence will repeat providing the system fault
still exists. The TPMS Warning Light will turn off
when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPM sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPM
sensors

64SAFETY
NOTE:
Your vehicle is equipped with a regular size
spare wheel.
1. The spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the spare tire.
2. If a spare tire not equipped with the Tire Pressure Monitoring sensor is used, the
TPMS Warning Light will turn on, flashing for
75 seconds and then remaining solid for
each subsequent ignition key cycle.
3. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the spare tire, the TPMS will update auto -
matically and the Tire Pressure Monitoring
Light will extinguish once the updated tire
pressures have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
NOTE:
For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off
during each tire substitution.General Information

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints

20_VF_OM_EN_US_t.book Page 64

78SAFETY
(Continued)
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the appro -
priate response to impact events. The system is
calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that
require Side Air Bag occupant protection. In side
impacts, the Side Air Bags deploy inde -
pendently; a left side impact deploys the left
Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed. The Side Air Bags will not deploy in all side colli
-
sions, including some collisions at certain
angles, or some side collisions that do not
impact the area of the passenger compartment.
The Side Air Bags may deploy during angled or
offset frontal collisions where the front air bags
deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes.
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your protec -
tion in all collisions. They also help keep
you in position, away from an inflating Side
Air Bag. To get the best protection from the
Side Air Bags, occupants must wear their
seat belts properly and sit upright with their
backs against the seats. Children must be
properly restrained in a child restraint or
booster seat that is appropriate for the size
of the child.

STARTING AND OPERATING97
(Continued)
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.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, DRIVE, and Electronic
Range Select (ERS) shift positions. Manual
downshifts can be made using the ERS shift
control. Moving the gear selector into the ERS
(-/+) position (beside the DRIVE position) acti -
vates ERS mode, displays the current gear in
the instrument cluster, and prevents automatic
upshifts beyond this gear. In ERS mode,
toggling the gear selector forward (-) or rear -
ward (+) will change the highest available gear.
Refer to "Electronic Range Select (ERS) Opera -
tion" in this section for further information.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the ERS (+/-)
position (beside the DRIVE position). In ERS
mode, the transmission gear limit (1, 2, 3, etc.)
is displayed in the instrument cluster. Move the gear selector to the right (into the DRIVE [D]
position) for access to PARK, REVERSE, and
NEUTRAL.
Gear Ranges
Do not depress 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
accelerating. 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.
When parking on a level surface, you may shift
the transmission into PARK first, and then apply
the parking brake. When parking on a hill, apply the parking brake
before shifting the transmission to PARK, other
-
wise the load on the transmission locking mech -
anism may make it difficult to move the gear
selector out of 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 engine OFF.
Remove the ignition key.
WARNING!
Never use the PARK position as a substi -
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.

20_VF_OM_EN_US_t.book Page 97

STARTING AND OPERATING99
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 characteris -
tics under all normal operating conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, trav
-
eling into strong head winds, or while towing a
heavy trailer), select TOW/HAUL mode or use
the Electronic Range Select (ERS) shift control
(refer to “Electronic Range Select (ERS) Opera -
tion” in this section for further information) to
select a lower gear range. Under these condi -
tions, using a lower gear range will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
During cold temperatures, transmission opera -
tion 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 is inhibited until the transmis -
sion fluid is warm refer to the “Note” under
“Torque Converter Clutch” in this section.
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.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.

Refer to “Recreational Towing” in “Starting
And Operating” and “Towing A Disabled
Vehicle” in “In Case Of Emergency” for further
information.

102STARTING AND OPERATING
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis -
sion 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 auto -
matically disengages.
NOTE:
The torque converter clutch will not engage
until the transmission fluid and engine
coolant are 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 into Overdrive
when cold. This is normal. Using the Elec -
tronic Range Select (ERS) shift control, when
the transmission is sufficiently warm, will
demonstrate that the transmission is able to
shift into and out of Overdrive.
If the vehicle has not been driven for several
days, the first few seconds of operation after
shifting the transmission into gear may seem
sluggish. This is due to the fluid partially
draining from the torque converter into the
transmission. This condition is normal and
will not cause damage to the transmission.
The torque converter will refill within five
seconds after starting the engine.
POWER STEERING
The standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is inter -
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will
observe a substantial increase in steering
effort, especially at very low vehicle speeds and
during parking maneuvers. NOTE:
Increased noise levels at the end of the
steering wheel travel are considered normal
and do not indicate that there is a problem
with the power steering system.
Upon initial start-up in cold weather, the
power steering pump may make noise for a
short amount of time. This is due to the cold,
thick fluid in the steering system. This noise
should be considered normal, and it does not
in any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.

20_VF_OM_EN_US_t.book Page 102

106STARTING AND OPERATING
ParkSense Rear Park Assist Sensors
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 Park -
Sense 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 Alerts
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.
