186 STARTING AND OPERATING
If equipped, the electronic Trailer Sway Control (TSC) recog-
nizes a swaying trailer and automatically 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
The weight-distributing hitch 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
accordance 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 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.
WARNING!
• An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking perfor -
mance, and could result in a collision.
• Weight Distributing Systems may not be compatible with Surge Brake Couplers. Consult with your hitch
and trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.

IN CASE OF EMERGENCY 229
Insert the power plug into the vehicle power outlet socket.
Start the vehicle engine.
Push the Tire Service Kit power button to the “I” position.
The electric compressor will be turned on, sealant and air
will inflate the tire.
Minimum 26 psi (1.8 bar) of pressure should be reached
within 20 minutes. If the pressure has not been reached, turn
off and remove the Tire Service Kit, drive the vehicle 30 feet
(10 meters) back and forth, to better distribute the sealant
inside the tire.
Attach the clear flexible filling tube of the compressor
directly to the tire valve and repeat the inflation process.
When the correct pressure has been reached, start driving the
vehicle to uniformly distribute the sealant inside the tire.
After 10 minutes, stop and check the tire pressure. If the
pressure is below 19 psi (1.3 bar), do not drive the vehicle, as
the tire is too damaged, contact the nearest authorized
dealer.
• A loose Tire Service Kit thrown forward in a collision
or hard stop could endanger the occupants of the
vehicle. Always stow the Tire Service Kit in the place
provided. Failure to follow these warnings can result in
injuries that are serious or fatal to you, your passengers,
and others around you.
• Take care not to allow the contents of Tire Service Kit to come in contact with hair, eyes, or clothing. Tire
Service Kit sealant is harmful if inhaled, swallowed, or
absorbed through the skin. It causes skin, eye, and
respiratory irritation. Flush immediately with plenty of
water if there is any contact with eyes or skin. Change
clothing as soon as possible, if there is any contact with
clothing.
• Tire Service Kit Sealant solution contains latex. In case of an allergic reaction or rash, consult a physician
immediately. Keep Tire Service Kit out of reach of chil -
dren. If swallowed, rinse mouth immediately with
plenty of water and drink plenty of water. Do not
induce vomiting! Consult a physician immediately.WARNING! (Continued)

IN CASE OF EMERGENCY 239
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode.
If the ignition key is unavailable, or the vehicle's battery is
discharged, refer to “Gear Selector Override” in this section
for instructions on shifting the transmission out of PARK (P)
for towing. The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, this vehicle must be
towed with the front wheels OFF the ground (using a towing
dolly, or wheel lift equipment with the front wheels raised).
CAUTION!
• Do not use sling type equipment when towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not attach to front or rear suspension components. Damage
to your vehicle may result from improper towing.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission damage.
Damage from improper towing is not covered under the
New Vehicle Limited Warranty.
