1-35 Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's basic
structure isn't changed, it's not likely to keep the
air bags from working properly in a crash.
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may not
work properly if you relocate any of the air bag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. (The phone numbers and
addresses for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
See ªCustomer Satisfaction Procedureº in the Index.)
Q:What if I add a snow plow? Will it keep the air
bags from working properly?
A:We've designed our air bag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles equipped
with the optional Snow Plow Prep Package (RPO
VYU). But don't change or defeat the snow plow's
ªtripping mechanism.º If you do, it can damage
your snow plow and your vehicle, and it may cause
an air bag inflation.

Center Passenger Position
Lap Belt
If your vehicle has front and rear bench seats, someone
can sit in the center positions.
When you sit in a center seating position, you have a lap
safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.

1-37
To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. If the belt isn't long enough,
see ªSafety Belt Extenderº at the end of this section.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt quickly
if you ever had to.
Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

1-38 Rear Seat Outside Passenger Positions
(Extended Cab)
Lap-Shoulder Belt (Extended Cab)
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted. The shoulder belt may lock if
you pull the belt across you very quickly. If this
happens, let the belt go back slightly to unlock it.
Then pull the belt across you more slowly.

2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you'd be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of the
body are best able to take belt restraining forces.The safety belt locks if there's a sudden stop or a crash.
The safety belt also locks if you pull the belt very
quickly out of the retractor.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.

To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
If your vehicle has a rear seat, your vehicle has shoulder
belt comfort guides. This feature will provide added
safety belt comfort for children who have outgrown
child restraints and for small adults. When installed on a
shoulder belt, the comfort guide pulls the belt away
from the neck and head.There is one guide for each outside passenger position in
the rear seat. To provide added safety belt comfort for
children who have outgrown child restraints and for
smaller adults, the comfort guides may be installed on
the shoulder belts. Here's how to install a comfort guide
and use the safety belt:
1. Remove the guide from its storage clip on the
interior body.

2. Place the guide over the belt and insert the two edges
of the belt into the slots of the guide.3. Be sure that the belt is not twisted and it lies flat. The
guide must be on top of the belt.
