If an impact is given to the moon roof, this function may
work without anything caught.

CAUTION
To avoid serious personal injury, you must do the
following.
While the vehicle is moving, always keep the head,
hands and other parts of the body of all occupants
away from the roof opening. Otherwise, you could be
seriously injured if the vehicle stops suddenly or if
the vehicle is involved in an accident.
 Always make sure nobody places his/her head,
hands and other parts of the body in the roof opening
before you close the roof. If someone's neck, head or
hands gets caught in the closing roof, it could result
in a serious injury. When anyone closes the roof, first
make sure it is safe to do so.
 Never leave small children alone in the vehicle,
especially with the ignition key still inserted. They
could use the moon roof switches and get trapped in
the roof opening. Unattended children can become
involved in serious accidents.
 Never sit on top of the vehicle around the roof
opening.

if you have a little mechanical ability and a few basic
automotive tools. Simple instructions for how to perform
them are presented in Section 6.
If you are a skilled do±it±yourself mechanic, the Lexus
service manuals are recommended. Please be aware

BODY
472To help prevent corrosion on your Lexus, follow
these guidelines:
Keep your vehicle clean by regular washing.
In
addition, observe the following points.

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
corrosion.

High pressure water or steam is effective 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 them. 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 thoroughly when
winter is over.
See ºWashing and waxingº for more tips.
Check the cond ition of your vehicle's paint and trim.
If you find any chips or scratches in the paint, touch them
up immediately to prevent corrosion from starting. If the
chips or scratches have gone through the bare metal,
have a qualified body shop make the repair. Check the interior of your vehicle. Water and dirt can
accumulate under the floor mats and could cause
corrosion. Occasionally check under the mats to make
sure the area is dry. Be particularly careful when
transporting chemicals, cleansers, fertilizers, salt, etc.
These should be transported in proper containers. If a
spill or leak should occur, immediately clean and dry the
area.
Keep your vehicle in a well ventilated garage or a
roofed place. Do not park your vehicle in a damp,
poorly ventilated garage.
If you wash your vehicle in
the garage, or if you drive it in covered with water or
snow, your garage may be so damp it will cause
corrosion. Even if your garage is heated, a wet vehicle
can corrode if the ventilation is poor.
