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 ESC Activation/Malfunction Indicator Light
(in the instrument cluster) will start to flash as
soon as the tires lose traction and the wheels
begin to spin. This indicates that the TCS is
active. If the indicator light flashes during accel -
eration, ease up on the accelerator and apply as
little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road condi -
tions, and do not switch off the ESC or TCS.

Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (TSC) uses sensors in the
vehicle to recognize an excessively swaying
trailer and will take the appropriate actions to
attempt to stop the sway. The system may reduce engine power and apply the brake of
the appropriate wheel(s) to counteract the
sway of the trailer. TSC will become active
automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda
-
tions. Refer to “Trailer Towing” in “Starting And
Operating” for further information.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced, and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard pres -
sure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after a three hour period. The
cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the
tire sidewall. Refer to “Tires” in “Servicing And
Maintenance” for information on how to prop -
erly inflate the vehicle’s tires. The tire pressure
will also increase as the vehicle is driven - this is
normal and there should be no adjustment for
this increased pressure.
WARNING!
The TCS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded.
The TCS cannot prevent collisions,
including those resulting from excessive
speed in turns, or hydroplaning.
The capabilities of a TCS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.

Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
Important Safety Precautions
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passen -
gers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
1. Children 12 years old and under should always ride buckled up in the rear seat of a
vehicle with a rear seat.
2. A child who is not big enough to wear the vehicle seat belt properly (Refer to “Child
Restraints” in this section for further infor -
mation) must be secured in the appropriate
child restraint or belt-positioning booster
seat in a rear seating position. 3. If a child from 2 to 12 years old (not in a
rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint (Refer to “Child Restraints” in this
section for further information).
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that
you are using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow
the front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deploy -
ment occurs, the side air bags will inflate
forcefully into the space between occupants
and the door and occupants could be
injured. 9. If the air bag system in this vehicle needs to
be modified to accommodate a disabled
person, refer to the “Customer Assistance”
section for customer service contact infor -
mation.WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.

Installing Child Restraints In Commercial Vehicles
This commercial vehicle is not designed for use
as a family vehicle and is not intended for
carrying children in the front passenger seat(s).
Never install rear-facing child restraints in this
vehicle. Although the seat belt can be locked to
secure a child restraint, there are no tether
anchorages to complete the proper installation
of a forward-facing child restraint. If you must
carry a child in a forward-facing child restraint,
the passenger seat should be moved to the full
rearward position and the child must be in a
proper restraint system based on its age, size
and weight. Follow the instructions below to
secure the child restraint using the seat belt.
Installing Child Restraints Using The Vehicle Seat
Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
The seat belts in the passenger seating posi -
tions are equipped with a Switchable Automatic
Locking Retractor (ALR). This seat belt is
designed to keep the lap portion of the seat belt
tight around the child restraint so that it is not
necessary to use a locking clip. The ALR
retractor can be “switched” into a locked mode
by pulling all of the webbing out of the retractor
and then letting the webbing retract back into
the retractor. If it is locked, the ALR will make a
clicking noise while the webbing is pulled back
into the retractor. Refer to the “Automatic Locking Mode” description in “Switchable Auto
-
matic Locking Retractors (ALR)” under “Occu -
pant Restraint Systems” for additional
information on ALR.
Front Bucket Seat Automatic Locking Retractor (ALR) Location
WARNING!
Rear-facing infant restraints must never be
secured in the passenger seat of a vehicle
with a passenger air bag. In a collision, a
passenger air bag may deploy causing severe
injury or death to infants riding in rear-facing
infant restraints.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure
of the restraint. The child could be badly
injured or killed.
Follow the child restraint manufacturer’s
directions exactly when installing an infant
or child restraint.

114STARTING AND OPERATING
Tongue Weight (TW)
The Tongue Weight (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 multi -
plied by the maximum width of the front of a
trailer.
Trailer Sway Control
The Trailer Sway Control (TSC) can be a
mechanical telescoping link that can be
installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion
to dampen any unwanted trailer swaying
motions while traveling. If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies indi
-
vidual wheel brakes and/or reduces engine
power to attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer
tongue weight, just as if it were luggage located
at a hitch ball or some other connecting point of
the vehicle. These kinds of hitches are the most
popular on the market today and they are
commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute
trailer tongue weight to the tow vehicle's front
axle and the trailer axle(s). When used in accor -
dance with the manufacturer's directions, it
provides for a more level ride, offering more
consistent steering and brake control thereby
enhancing towing safety. The addition of a fric -
tion/hydraulic sway control also dampens sway
caused by traffic and crosswinds and contrib -
utes positively to tow vehicle and trailer
stability. Trailer sway control and a weight distributing (load equalizing) hitch are recom
-
mended for heavier Tongue Weights (TW) and
may be required depending on vehicle and
trailer configuration/loading to comply with
Gross Axle Weight Rating (GAWR) requirements.
Trailer Hitch Classification
The following chart provides the industry stan -
dard for the maximum trailer weight a given
trailer hitch class can tow and should be used to
assist you in selecting the correct trailer hitch
for your intended towing condition.
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.
WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling,
stability, braking performance, and could
result in a collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manufac -
turer or a reputable Recreational Vehicle
dealer for additional information.
