Vehicle Damage  Warnings 
Also, in this  book  you  will find these  notices: 
Notice: These mean there is something that could 
damage  your  vehicle. 
A notice will tell  you  about  something  that can damage 
your vehicle.  Many  times, this damage  would  not  be 
covered  by your  warranty, and  it  could  be costly. 
But  the notice will tell  you what  to do  to  help avoid the 
damage. 
When  you read other  manuals, you might  see 
CAUTION  and  NOTICE  warnings  in different colors 
or 
in different words. 
You’ll  also see warning labels 
on your vehicle.  They 
use  the  same  words,  CAUTION  or NOTICE. 
Vehicle Symbols 
Your  vehicle  has  components  and  labels that use 
symbols  instead of text.  Symbols,  used  on  your  vehicle, 
are  shown  along with  the text describing the operation 
or  information relating to  a specific  component,  control, 
message,  gage  or  indicator. 
If you  need help figuring  out a specific name of a 
component,  gage  or  indicator reference the following

Front Seats 
Manual Seats 
You can lose control of the vehicle  if you  try  to 
adjust a manual driver’s  seat  while  the  vehicle 
is moving.  The sudden movement could startle 
and  confuse  you,  or make you  push 
a pedal 
when  you  don’t  want  to.  Adjust the  driver’s 
seat  only  when the vehicle is not moving. 
If your  vehicle is  equipped with manual  seats,  lift the 
lever, located  under the front 
of the seat,  using  a twisting 
motion. This will  unlock the  seat. Slide the  seat to 
where  you  want  it and release the lever. 
Try to move 
the  seat  back  and  forth to make  sure the  seat  is locked 
in  place.

Heated Seats 
If your vehicle  is equipped 
with this feature, the  heated seat  switch  is 
located on the center 
console, behind the 
open storage  bin. 
Reclining Seatbacks 
The  recliner lever for  the  driver’s and passenger’s  front 
seatback  is located on  the  outboard  side  of each 
front  seat  cushion. 
Press 
LO to  warm  the seat to a  lower temperature. 
Press 
HI to warm  the seat to  a  higher temperature. 
To  turn  this feature 
off, place the  switch in the center 
position. This feature only works when the  ignition 
is  turned  on. 
Lift the lever to  release the  seatback, then move  the 
seatback 
to where  you want  it.  Release  the  lever  to  lock 
the  seatback in place.  Pull  up on the lever  without 
pushing on the  seatback and the  seatback  will  move 
forward.

Safety  Belts 
Safety  Belts:  They  Are  for Everyone 
This part of the  manual  tells you  how to  use safety 
belts  properly. 
It also tells you some  things you  should 
not  do  with  safety  belts. 
Don’t  let  anyone  ride where  he  or  she can’t 
wear  a  safety  belt properly.  If  you are 
in a 
crash  and  you’re  not wearing  a  safety  belt, 
your  injuries  can  be much worse.  You  can 
hit 
things inside the vehicle  or be  ejected  from it. 
You  can  be  seriously injured or killed. In the 
same  crash,  you might  not  be, if you  are 
buckled 
up. Always  fasten your  safety  belt, 
and  check  that your  passengers’  belts are 
fastened  properly too. 
I 
It is extremely  dangerous to E*.-- .n a cargo 
area,  inside  or  outside  of  a  vehicle. 
In a 
collision,  people riding 
in these  areas  are  more 
likely  to be seriously  injured  or killed. Do not 
~ allow  people  to ride in any  area  of your  vehicle 
~ that is not  equipped  with seats  and  safety 
belts.  Be  sure everyone 
in your  vehicle is in a 
seat  and  using a  safety  belt properly. 
Your  vehicle has a light 
that comes  on as a 
reminder  to buckle up.

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.

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.
