The ABS contains sophisticated electronic
equipment that may be susceptible to interfer-
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.

If you use a trailer brake controller with your
trailer, the trailer brakes may be activated 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 accel-
eration, 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 transmission in
PARK (Pyf.
Failure to follow these warnings can result in a
collision or serious personal injury.

controlling vehicle speed when driving in
off-road conditions. The driver must remain
attentive to the driving conditions and is
responsible for maintaining a safe vehicle
speed.

A lap belt worn too high can increase the risk
of injury in a collision. The seat belt forces
won’t be at the strong hip and pelvic bones,
but across your abdomen. Always wear the lap
part of your seat belt as low as possible and
keep it snug.
A twisted seat belt may not protect you prop-
erly. In a collision, it could even cut into you.
Be sure the seat belt is flat against your body,
without twists. If you can’t straighten a seat
belt in your vehicle, take it to an authorized
dealer immediately and have it fixed.

A seat belt that is buckled into the wrong
buckle will not protect you properly. The lap
portion could ride too high on your body,
possibly causing internal injuries. Always
buckle your seat belt into the buckle nearest
you.

A seat belt that is too loose will not protect you
properly. In a sudden stop, you could move too
far forward, increasing the possibility of injury.
Wear your seat belt snugly.

Wearing your seat belt incorrectly could make
your injuries in a collision much worse. You
might suffer internal injuries, or you could
even slide out of the seat belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
Position the shoulder belt across the shoulder
and chest with minimal, if any slack so that it
is comfortable and not resting on your neck.

shoulder belt.
Misadjustment of the seat belt could reduce
the effectiveness of the safety belt in a crash.
Always make all seat belt height adjustments
when the vehicle is stationary.
WARNING!
ONLY use a Seat Belt Extender if it is physically
required in order to properly fit the original
seat belt system. DO NOT USE the Seat Belt
Extender if, when worn, the distance between
the front edge of the Seat Belt Extender
buckle and the center of the occupant’s body
is LESS than 6 inches.
Using a Seat Belt Extender when not needed
can increase the risk of serious injury or death
in a collision. Only use the Seat Belt Extender
when the lap belt is not long enough and only
use in the recommended seating positions.
Remove and store the Seat Belt Extender
when not needed.

different than the occupant’s properly seated
weight input, which may result in serious injury
or death in a collision.

Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the

injury or death in a collision. Do not place any
objects on the floor under the front passenger
seat.
