CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear
-facing child
restraint would be very close to the inflating air
bag. Always secure a rear
-facing child restraint
in the rear seat.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.You'll be using the lap
-shoulder belt. See the earlier part
about the top strap if the child restraint has one. Be sure
to follow the instructions that came with the child
restraint. Secure the child in the child restraint when and
as the instructions say.
1. Because your vehicle has a right front passenger air
bag, always move the seat as far back as it will go
before securing a forward
-facing child restraint. (See
ªSeatsº in the Index.)
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

CAUTION:
Inflating something too much can make it
explode, and you or others could be injured. Be
sure to read the inflator instructions, and inflate
any object only to its recommended pressure.
To use your air inflator, attach the appropriate nozzle
adapter, if required, to the end of the hose.
Then attach that end of the
hose to the object you wish
to inflate. Remove the
protective cap covering the
outlet. Attach the other end
of the hose to the outlet.
Press the ON switch.If the air inflator system does not turn on, the fuse may
be blown or installed incorrectly. See ªFuses and Circuit
Breakersº in the Index or see your dealer for service.
Your air inflator will automatically shut off after about
10 minutes. To reset, press the ON switch again.
Don't run your air inflator for longer than 30 minutes at
one time. If you do, you may damage the system. After
30 minutes, wait at least 10 minutes before restarting the
air inflator.
To turn off the air inflator, press OFF and detach the
hose, first from the inflated object, then from the outlet.
Replace the protective cap. Place the inflator kit tools in
the pouch and store it properly.
To replace the cover, line up the tabs at the back of the
cover and put it in place.
