5. To make the lap part  tight,  pull down on the buckle 
end 
of the belt as  you pull up on the  shoulder  belt.  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  faal injuries.  The  shoulder  belt  should  go 
over  the  shoulder  and  across  the  chest.  These  parts 
of the 
body  are  best  able  to  t,&e belt  restraining  forces. 
The safety  belt locks 
if there's  a sudden  stop or crash,  or 
if you pull the  belt  very  quickly out of the  retractor.

What’s  wrong  with  this? 
A: The shoulder belt is too loose. It won’t give  nearly 
as much protection  this way. 
I--- 1 
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.

A: The belt is buckled in the wrong place. 
You can be seriously  injured if your belt is 
buckled  in  the wrong place like  this. In a crash, 
the  belt  would  go  up over your abdomen.  The 
belt forces  would  be there, not at the  pelvic 
bones.  This could  cause  serious  internal  injuries. 
Always  buckle your belt  into  the buckle 
nearest 
you.

A: The  shoulder belt is worn under the arm. It should 
be  worn  over 
the shoulder  at  all times. 
You can be seriously  injured if you wear  the 
shoulder belt  under your arm.  In 
a crash,  your 
body  would  move 
too far forward,  which  would 
increase  the chance 
of head  and neck  injury. 
Also,  the belt  would  apply too much force  to  the 
ribs,  which  aren't  as  strong 
as shoulder bones. 
You  could also  severely injure  internal  organs 
like your liver  or spleen.

@ What’s  wrong  with  this? 
A: The belt is twisted across the body. 
You can  be  seriously  injured  by  a twisted  belt.  In 
a  crash,  you  wouldn’t  have  the  full  width 
of the 
belt  to spread  impact  forces. 
If a belt  is  twisted, 
make  it  straight 
so it  can  work  properly, or ask 
your  dealer  to 
fix it.

Safety  Belt  Use  During  Pregnancy 
Safety  belts  work  for  everyone,  including  pregnant 
women.  Like  all  occupants,  they are  more  likely  to  be 
seriously  injured 
if they  don't  wear  safety  belts. 
To unlatch  the  belt,  just  push  the  button  on the  buckle. 
The  belt  should 
go back  out  of the  way. 
Before  you close  the  door, be  sure  the  belt  is out 
of the 
way.  If you 
slarn the  door on it,  you  can  damage  both  the 
belt  and  your  vehicle. 
A pregnant  woman should wear a  lap-shoulder  belt,  and 
the  lap  portion  should  be  worn as low  as  possible,  below 
the rounding,  throughout  the  pregnancy.

The best way to protect  the  fetus is to protect the 
mother. When 
a safety belt  is worn properly,  it’s  more 
likely that the 
fetus won’t be hurt  in a crash.  For 
pregnant women, 
as for  anyone,  the key to making 
safety belts effective is wearing them properly. 
Right  Front  Passenger  Position 
To learn how to wear the right  front passenger’s safety 
belt properly, see “Driver  Position”  earlier in 
this section. 
The  right  front  passenger’s  safety  belt works the  same 
way  as the driver’s safety belt 
-- except for  one thing. If 
you  ever  pull the  shoulder  portion of the  belt out all the 
way,  you  will  engage the child  restraint locking  feature. 
If  this happens,  just let the  belt 
go back  all the  way  and 
start again. 
Supplemental Inflatable Restraint 
(SIR) System 
This  part explains  the Supplemental  Inflatable Restraint 
(SIR) system or air  bag  system. 
Your  vehicle has “Next Generation” reduced-force 
frontal air bags 
-- one  air  bag  for  the  driver and another 
air  bag  for the right front passenger. 
Reduced-force  frontal  air bags  are designed  to  help 
reduce the risk 
of injury  from the force  of  an inflating 
air  bag. But  even these  air bags must inflate  very 
quickly  if they are  to do  their 
job and  comply  with 
federal  regulations.

Here  are  the most important things to know about the  air 
bag system: 
You can be  severely  injured or killed  in a crash if 
you  aren’t  wearing  your safety  belt 
-- even  if  you 
have 
air bags.  Wearing  your  safety  belt  during a 
crash  helps  reduce  your  chance  of hitting  things 
inside  the vehicle  or being  ejected  from it.  Air  bags 
are  “supplemental  restraints”  to the safety  belts. 
All air bags -- even  reduced-force  air bags -- are 
designed  to work  with  safety  belts,  but don’t 
replace  them.  Air  bags  are designed  to  work  only 
in  moderate to  severe crashes  where the front  of 
your  vehicle  hits  something.  They  aren’t  designed 
to  inflate  at all  in  rollover,  rear,  side  or low-speed 
frontal  crashes.  And,  for unrestrained  occupants, 
reduced-force  air bags  may  provide  less  protection 
in  frontal crashes than  more  forceful 
air bags  have 
provided  in  the  past.  Everyone  in  your  vehicle 
should  wear 
a safety  belt  properly -- whether or 
not  there’s  an  air bag for that  person. 
I 
Air bags  i ate  with  great  force,  faster  than  the 
blink  of 
an eye. If you’re too close to an  inflating 
air  bag,  it could  seriously  injure you. This  is true 
even  with reduced-force  frontal  air bags. Safety 
belts help keep  you in  position  before and  during 
a crash. Always  wear your  safety belt, even  with 
reduced-force  air bags.  The  driver  should sit as 
far  back 
as possible  while  still maintaining 
control  of the  vehicle.

r- 
Children who ar ~p  against, or very  close  to, an 
air  bag  when  it inflates can  be seriously  injured 
or  killed.  This is true  even  though your  vehicle 
has  reduced-force  frontal air bags. 
Air bags plus 
lap-shoulder  belts offer  the best protection  for 
adults,  but  not for young children  and infants. 
Neither  the vehicle’s  safety belt  system nor its air 
bag  system  is designed  for them.  Young  children 
and  infants  need the protection  that a child 
restraint  system can provide.  Always secure 
children properly  in your  vehicle. 
To read how, 
see  the  part  of this  manual  called “Children”  and 
see  the  caution labels  on the  sunvisors  and  the 
right  front  passenger’s safety  belt. 
There is an air  bag  readiness 
light 
on the instrument 
panel, which shows  the air 
bag  symbol. 
The  system checks the  air bag electrical system  for 
malfunctions.  The light tells 
you if there is an electrical 
problem.  See “Air 
Bag Readiness Light” in the Index 
for 
more information.

How the Air Bag System Works 
Where  are  the  air bags? 
The  driver’s  air bag is in  the  middle  of the 
steering  wheel.  The 
right  front  passenger’s  air  bag is  in  the instrument 
panel  on the  passenger’s  side.
