Q: If I’m a good driver, and I never drive far from 
A: You  may  be an  excellent driver, but if you’re  in an 
accident 
- even  one  that  isn’t your fault - you and 
your  passengers  can be hurt. Being  a  good 
driver  doesn’t protect  you from things  beyond your 
control,  such as bad drivers. 
Most accidents occur within 
25 miles (40 km)  of 
home.  And the greatest  number of serious injuries 
and  deaths occur  at  speeds of less than 
40 mph (65 km/h). 
Safety belts are  for everyone. 
home,  why should I wear  safety  belts? 
How to Wear  Safety  Belts  Properly 
This  part  is only for  people  of adult  size. 
Be  aware  that there are  special  things 
to know  about 
safety belts and children.  And there are  different 
rules for  smaller children  and babies.  If  a child  will  be 
riding  in your vehicle,  see Older Children  on  page 
1-29 
or Infants  and Young  Children  on  page 1-32. Follow 
those rules for  everyone’s protection. 
First, you’ll  want to know  which  restraint systems  your 
vehicle  has. 
We’ll  start with  the driver  position. 
Driver  Position 
This  part describes the  driver’s  restraint  system. 
Lap-Shoulder Belt 
The driver  has a lap-shoulder belt.  Here’s  how to wear 
it properly. 
1. Close  and  lock the  door. 
2.  Adjust the seat 
so you  can  sit  up  straight. 
To see  how,  see  “Seats’’  in the  Index. 
1-12  

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. 
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  on page 7-12. 
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.

Rear  Safety  Belt  Comfort Guides for 
Children and  Small  Adults Here’s how  to  install a  comfort  guide  and  use  the 
safety  belt: 
Your  vehicle may have this feature already.  If it doesn’t, 
you  can  get it from any 
GM dealer. 
Rear shoulder belt comfort guides will provide added 
safety  belt comfort  for  older children who have outgrown 
booster seats and  for small  adults.  When  installed on 
a  shoulder belt, the comfort guide  better positions 
the  belt  away  from the  neck and head. 
There  is one  guide available  for each outside passenger 
position in the  rear  seat. To provide added safety belt 
comfort for  children  who have outgrown child  restraints 
and  booster seats and  for  smaller adults, the 
comfort  guides may  be installed on the shoulder belts. 
1. Pull the elastic cord  out  from  between  the  edge  of 
the seatback and the interior  body to remove  the 
guide  from its storage  clip.

Child  Restraints 
Older Children 
Older  children who have  outgrown booster  seats should 
wear  the  vehicle’s  safety  belts. 
If  you  have  the  choice,  a child should sit next to  a 
window 
so the  child  can  wear  a  lap-shoulder belt and 
get  the  additional  restraint  a shoulder belt can  provide. 
Q: What is the  proper way to wear  safety  belts? 
A: If possible, an older child should wear  a 
lap-shoulder belt and  get the additional restraint a 
shoulder belt can provide.  The shoulder 
belt 
should not cross the  face  or  neck. The  lap belt 
should  fit snugly below the hips, just  touching  the 
top  of the thighs.  It should  never be worn  over 
the  abdomen,  which could cause severe  or even 
fatal  internal injuries in a  crash. 
Accident statistics  show  that children are safer 
if they 
are restrained  in the  rear  seat. 
In  a crash, children  who  are  not buckled up can strike 
other  people  who  are  buckled up, or can  be thrown 
out  of the vehicle. Older children need to  use safety 
belts properly. 
1-29  

Never do  this. 
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  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 sitting  in a  rear  seat  outside position,  see 
Rear  Safety Belt  Comfort  Guides  for  Children 
and 
Small Adults on page 7-26. If the child is so small 
that  the shoulder  belt is still  very  close to the  child’s 
face 
or neck,  you  might  want  to place the child  in the 
center seat position, the  one  that  has only 
a lap belt.
