Seats and Restraints 53
{Warning
To help avoid personal injury or
death during a collision or sudden
maneuver, always thread both the
lap and shoulder belt through the
locking clip when securing a child
restraint on the outboard seat.
If the clip is not used or installed
properly, the child restraint may
move or tip over when your
vehicle turns or stops abruptly.
Secure the child restraint with the
lap belt portion (1) of the seat belt in
accordance with the restraint
manufacturer's instructions. Then
thread both the lap (1) and shoulder
belt (2) portions through the locking
clip. Push and pull the child restraint
in all directions to be sure it is
secure.
Locking Clip Attached to Seat Belt–Side View
1. Lap Belt
2. Shoulder Belt
3. Locking Clip
When your child restraint is not
installed, remove the locking clip to
permit normal use of the
lap-shoulder belt. Keep the locking
clip in the glove box to help prevent
its loss.
Child Restraint with Top Tether
{Warning
We do not recommend using a
child restraint that requires the
use of a top tether. There is no
appropriate place to attach a top
tether anchor behind the seat in
this vehicle.

324 Vehicle Care
Warning (Continued)
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.
Open all vehicle doors for
ventilation when ANY cleaning
agents or other chemicals are
used in the interior. Overexposure
to some vapors may result in a
health problem that is more likely
to occur in small, unventilated
spaces.
You and others could be seriously
injured.
The interior of the vehicle must
never be cleaned using acidic or
alkaline solvents, or petroleum
ether, gasoline, and other organic
solvents. Failure to observe this
precaution can result in
discoloration and staining. It should
be noted that certain types of
cleaning products contain these
compounds. Be sure to read
cleaning product labels carefully. Air fresheners (liquid, solid, gel,
or plate types) must not come into
direct contact with, or spill onto,
interior components such as the air
conditioning or audio system.
Compounds contained in these
products can cause discoloration,
staining, or peeling of paint.
Glass cleaners that contain these
compounds must not be used to
clean the inside of the windshield or
window glass. To clean the glass,
wipe it using a cloth wet with warm
or cold water.
To avoid possible permanent
discoloration of light colored seats,
Do not let materials with non-fast
colors come into contact with seat
trim materials until these materials
are totally dry. This includes certain
types of casual clothing, such as
colored denims, corduroys, leathers,
and suedes, as well as decorative
paper.
With the use of modern trim
materials, it is very important that
you use proper cleaning techniques
and cleaners. Failing to do this on
the first cleaning may result in waterspots, spot rings, or setting of stains
or soilage
—all of which are more
difficult to remove in a second
cleaning.
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots,
or stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
. Remove stains as quickly as
possible before they set.
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
