lukewarm water, and a soft sponge.
A chamois or cloth may leave lint on
the top, and a brush can chafe the
threads in the top fabric. Do not use
detergents, harsh cleaners,
solvents, or bleaching agents.
Wet the entire top and let the soap
remain on the fabric for a few
minutes. Wash evenly to avoid
spots or rings. When the top is very
dirty, use a mild foam-type cleaner.
Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight. To protect the convertible top:

Make sure the convertible top is
completely dry before lowering it.

leave streaks.

Head Restraints
{ WarningWith head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly. Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
Front Seats The vehicle's front seats have
adjustable head restraints in the
outboard seating positions.
To raise or lower the head restraint,
press the button on the side of the
head restraint, and pull up or push
the head restraint down, and
release the button. Pull and push on the head restraint after the button is
released to make sure that it is
locked in place.
To adjust the head restraint forward,
grasp the head restraint and pull
forward to the desired locked
position. To adjust the head restraint
rearward, grasp the head restraint
and pull forward fully, until the
mechanism releases and allows the
head restraint to return to the full
rear position.

their job.
The shoulder belt will not be
against your body. Instead, it will
be in front of you. In a crash, you
could go into it, receiving neck or
other injuries.
The lap belt could go up over
your abdomen. The belt forces
would be there, not at your pelvic
bones. This could cause serious
internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
seat belt properly.
