If both front doors are
closed, the moon roof works for about 43
seconds even after the engine switch is
turned off. It stops working when either
door is opened.
Jam protection function:
If something gets caught between the
moon roof and frame during slide clos-
ing operation, the moon roof stops and
opens, and the deflector stops and
raises fully.
If something gets caught between the
moon roof and frame during tilting
down operation, the moon roof stops
and opens fully.
If the moon roof receives a strong impact,
this function may work even if nothing is
caught.
If the moon roof does not operate auto-
matically or the jam protection function
does not operate correctly, you should
normalize the moon roof.
To normalize the moon roof, push and
hold the switch toward the “UP” (tilt up)
side or “

HITCHES
If you wish to install a trailer hitch, you
should consult with your Toyota dealer.
Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the gross trailer weight
requirement.
The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer ’s instruc-
tions.
The hitch ball and king pin should have
a light coat of grease.
Toyota recommends removing the trail-
er hitch whenever you are not towing
a trailer to reduce the possibility of
additional damage caused by the hitch
if your vehicle is struck from behind.
After removing the hitch, seal any
mounting holes in the vehicle body to
prevent entry of pollutants such as ex-
haust fumes, dirt, water, etc. TRAILER BALL
Follow these easy steps to properly deter-
mine the correct trailer ball for your ap-
plication:
1. Determine the correct trailer ball size for the trailer coupler. Most couplers
are stamped with the required trailer
ball size. The sizes you will most likely
find stamped on the coupler are:
Trailer class
Typical trailer ball size
IV2 5/16 in.
II and III2 in.
I1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the gross trailer
weight rating of the trailer. The trailer
ball load rating should be printed on
the top of the ball.
3. When mounted in the ball mount, the threaded ball shank must protrude be-
yond the bottom of the lock washer
and nut at least 2 threads. The trailer
ball shank must be matched to the ball
mount hole diameter size.

3. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen. To get maximum leverage,
fit the wrench to the nut so that the
handle is on the right side, as shown
above. Grab the wrench near the end
of the handle and pull up on the han-
dle. Be careful that the wrench does
not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one −half turn.
CAUTION
Never use oil or grease on the
bolts or nuts. The nuts may loose
and the wheels may fall off,
which could cause a serious ac-
cident.

Toyota, through its diligent research, de-
sign and use of the most advanced
technology available, helps prevent corro-
sion and provides you with the finest qual-
ity vehicle construction. Now, it is up to
you. Proper care of your Toyota can help
ensure long −term corrosion prevention.
The most common causes of corrosion
to your vehicle are:
The accumulation of road salt, dirt and
moisture in hard −to −reach areas under
the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:
Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea −
coast or in areas of industrial pollution.
High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.
Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High ambient temperatures can cause
corrosion to those components of the
vehicle which do not dry quickly due to
lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:
If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.
High pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing. The
lower edge of doors, rocker panels and
frame members have drain holes which
should not be allowed to clog with dirt
as trapped water in these areas can
cause corrosion.
Wash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Toyota” on
page 527 in this Section for more tips.
Check the condition of your vehicle’s
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.

Do not reuse iridiumtipped spark
plugs by cleaning or regapping.
 Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.
 When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.Here is a list of parts and tools you will
need to perform do− it−yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
