Hill Descent Control (HDC) — If
Equipped
This system maintains vehicle speed while de-
scending hills during off-road driving situations.
HDC will automatically apply the brakes to
control downhill speed to between 4 mph
(7 km/h) and 6 mph (9 km/h) depending on
terrain. The system is activated by placing the
vehicle in “Off-Road” mode and placing the gear
selector in LOW or REVERSE. Refer to “Off-
Road Driving Tips” in “Starting And Operating”
for further information.
When HDC is properly enabled,
the “Hill Decent Control Light” in
the instrument cluster will be
illuminated.
HDC has the capability to sense terrain and will
only activate when the vehicle is descending a
hill. It will not activate on level ground. If desired,
HDC can be fully deactivated by putting the
vehicle into ESC “Full Off” mode. This is done
by pushing and holding the “ESC Off” button for
five seconds. Refer to “Electronic Stability Con-
trol (ESC)” in this section of the manual.HDC operation can be overridden with brake
application to slow the vehicle down below the
HDC control speed. Conversely, if more speed
is desired during HDC control, the accelerator
pedal will increase vehicle speed like normal.
When either the brake or the accelerator is
released, HDC will control the vehicle back to
the original set speed.
HDC is only intended for low speed off-road
driving. At vehicle speeds above 31 mph (50
km/h), HDC will no longer function. If the “HDC
Indicator Light” begins to flash, this indicates
that the brakes are getting too hot and the
vehicle should be stopped to allow the brakes to
cool.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for
maintaining a safe vehicle speed.
TIRES — GENERAL
INFORMATION
Tire PressureProper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
•Safety and Vehicle Stability
•Economy
•Tread Wear
•Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous
and can cause collisions.
•Underinflation increases tire flexing and
can result in overheating and tire failure.

Trailer Sway ControlThe trailer sway control 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 Trailer Sway Control
(TSC) recognizes a swaying trailer and auto-
matically applies individual 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 frontaxle and the trailer axle(s). When used in ac-
cordance 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
friction/hydraulic sway control also dampens
sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer
stability. Trailer sway control and a weight dis-
tributing (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) require-
ments.
WARNING!
•An improperly adjusted Weight Distributing
Hitch system may reduce handling, stabil-
ity, braking performance, and could result
in a collision.
(Continued)
WARNING!(Continued)
•Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manu-
facturer or a reputable Recreational Ve-
hicle dealer for additional information.
Breakaway Cable AttachmentEuropean braking regulations for braked trailers
up to 7,700 lbs (3,500 kg), require trailers to be
fitted with either a secondary coupling or break-
away cable.
The recommended location for attaching the
normal trailer’s breakaway cable is in the
stamped slot located on the sidewall of the hitch
receiver.

WARNING!
Improper towing can lead to an injury acci-
dent. Follow these guidelines to make your
trailer towing as safe as possible:
•Make certain that the load is secured in the
trailer and that it will not shift during travel.
When trailering cargo that is not fully se-
cured, dynamic load shifts can occur that
may be difficult for the driver to control. You
could lose control of your vehicle and have
an accident.
•All trailer hitches should be professionally
installed on your vehicle.
•When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance, or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure, or tires.
(Continued)
WARNING!(Continued)
•Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the frame or hook re-
tainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow
enough slack for turning corners.
•Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Always, block
or"chock"the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch
utilized.Towing Requirements — Tires
•Do not attempt to tow a trailer while using a
compact spare tire.
•Proper tire inflation pressures are essential
for the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
•Check the trailer tires for proper tire inflation
pressures before trailer usage.
•Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires – General Information” in “Starting and
Operating” for the proper inspection
procedure.
•When replacing tires, refer to “Tires – Gen-
eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle’s GVWR
and GAWR limits.
217

Towing Requirements — Trailer Brakes
–Donotinterconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
– When towing a trailer equipped with a hy-
draulic surge actuated brake system, an
electronic brake controller is not required.
– Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 1,653 lbs (749 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake
pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system and cause it to fail. You
might not have brakes when you need
them and could have an accident.
•Towing any trailer will increase your stop-
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an accident.
Towing Requirements – Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.The Trailer Tow Package may includea7ora
13–pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.

•If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
•Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
•Do not change the thermostat for Summer or
Winter operation. If replacement is ever nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be in-spected periodically. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be
checked when performing under hood services,
or immediately if the brake system warning light
is on.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the require-
ments described on the brake fluid reservoir.
Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be
checked when the pads are replaced. However,low fluid level may be caused by a leak and a
checkup may be needed.
NOTE:
If your vehicle is equipped with a manual
transmission, the brake fluid reservoir sup-
plies fluid to both the brake system and the
clutch release system. The two systems are
separated in the reservoir, and a leak in one
system will not affect the other system. The
manual transmission clutch release system
should not require fluid replacement during
the life of the vehicle. If the brake fluid
reservoir is low and the brake system does
not indicate any leaks or other problems, it
may be a result of a leak in the hydraulic
clutch release system. See your local autho-
rized dealer for service.
Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
