push the seatback toward the rear as you
lift this latch. Then the seatback
will fold forward. The latch must be down for the seat to work properly.

‘b Here two children are wearing the same belt. The belt can’t properly
spread
the impact forces. In a crash, the two children can be
crushed together and seriously injured.
A belt must be used by only
I one person at a time.
Q: What if a child is wearing a lap-shoulder belt, but the child is so
small that the shoulder belt is very close to the child’s face or neck?
A: Move the child toward the center of the vehicle, but be sure that the
shoulder belt still is on the child’s shoulder,
so that in a crash the child’s
upper body would have the restraint that belts provide. If the child is
so small
that the shoulder belt still is very close to the child’s face or neck, you might
want
to place the child in a seat that has a lap belt, if your vehicle has one.

1 NOTICE
Jr modern vehicle doesn’t need an elaborate “break-in.” But\
it will
perform better in the long run
if you follow these guidelines:
Keep your speed at 55 mph (88 kmlh) or less for the first 500 miles
(804 km).
Don’t drive at any one speed-fast or slow-for the first 500 miles
(804 km). Don’t make full-throttle starts.
Avoid making hard stops for the first 200 miles (322 km) or so.
During this time your new brake linings aren’t yet broken in. Hard
stops with new linings can mean premature wear and earlier
replacement. Follow this “breaking-in” guideline every time you get
new brake linings.
If you have
a 3500 HD Model, see “Parking Brake” in the Index.

loss of
power. In an emergency,
if the air cleaner is plugged with snow, you can
remove the air cleaner. Then, drive to a place
of safety as soon as possible
and put the air cleaner back on.
