CAUTION
To avoid serious personal injury, you
must do the following.

Always make sure the head, hands
and other parts of the body of all
occupants are kept completely in-
side the vehicle before you close
the power windows. If someone's
neck, head or hands gets caught in
a closing window, it could result in
a serious injury. When anyone
closes the power windows, be sure
that they operate the windows safe-
ly.

When small children are in the ve-
hicle, never let them use the power
window switches without supervi-
sion. Use the window lock switch to
prevent them from making unex-
pected use of the switches.

Never leave small children alone in
the vehicle, especially with the igni-
tion key still inserted. They could
use the power window switches and
get trapped in a window. Unat-
tended children can become in-
volved in serious accidents.
Trunk lidÐ
To open the trunk lid from the outside,
insert the master key and turn it clock-
wise.
See ªLuggage stowage precautionsº in
Section 2 for precautions in loading lug-
gage.
To close the trunk lid, lower it and press
down on it. After closing the trunk lid, try
pulling it up to make sure it is securely
closed.
CAUTION

Keep the trunk lid closed while
driving. This not only keeps the
luggage from being thrown out but
also prevents exhaust gases from
entering the vehicle.

Always lock the trunk lid and all
doors, and keep away the vehicle
keys out of children's reaches.

Never leave children unattended in
the vehicle. Unsupervised children
may lock themselves in the vehicle
or trunk and suffer serious injuries
or death.
