CAUTION
Before driving, be sure that the doors
are closed and locked, especially
when small children are in the ve-
hicle. Along with the proper use of
seat belts, locking the doors helps
prevent the driver and passengers
from being thrown out from the ve-
hicle during an accident. It also helps
prevent the doors from being opened
unintentionally.

CAUTION
To avoid serious personal injury, you
must do the following.
Always make sure the heads, hands
and other parts of the bodies of all
occupants are kept completely in-
side the vehicle before you close
the power windows. If someone’s
neck, head or hands get caught in
a closing window, it could result in
a serious injury. When anyone
closes the power windows, make
sure that he/she operates the win-
dows safely.
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 be involved in
serious accidents.
To open the trunk lid from the outside,
insert the master key and turn it clock-
wise.

To insert the support rod into the slot,
move it straight up. If it is moved to the
side or toward the inside of the vehicle,
it may become detached.

the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.

its clip before closing the hood. Clos-
ing the hood with the support rod up
