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 
topics: 
Seats  and  Restraint Systems in Section 1 
Features and Controls in Section 2 
Instrument Panel  Overview in Section 3 
Climate Controls in  Section 3 
Warning Lights, Gages  and  Indicators in Section 3 
Audio  System(s) in Section 3

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. 
See  Safety 
Belt Reminder 
Light on  page 
3-26.

        Page 20 of 378
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. 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. 
4. Push the  latch plate into the  buckle until  it clicks. 
Pull  up  on  the latch plate  to make  sure it  is secure. 
If 
the belt  isn’t  long  enough,  see  Safety  Belt Extender 
on page 1-28 at  the end of this section. 
5. To make  the  lap  part tight,  pull  down  on the  buckle 
end 
of the  belt  as you  pull up  on  the shoulder belt.

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.

There  is  a  air  bag readiness light on the  instrument 
panel,  which  shows 
SRS AIR BAG or  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 
on page 3-26 
for  more information. 
Where  Are  the Air Bags? 
The driver’s air bag is in the  middle  of the  steering 
wheel.

Restraint System Check 
Checking Your  Restraint  Systems 
Now and then,  make sure  the safety belt reminder light 
and  all your  belts, buckles, latch plates, retractors 
and  anchorages  are working properly.  Look  for  any other 
loose or  damaged  safety belt  system parts. If  you  see 
anything that might  keep  a safety belt  system from doing 
its  job,  have  it  repaired. 
Torn  or frayed safety belts  may not protect  you in a 
crash.  They can rip apart  under impact forces.  If  a belt 
is torn  or frayed, get  a  new  one right away. 
Also 
look for  any  opened or  broken air  bag covers, and 
have  them  repaired  or replaced. (The  air  bag  system 
does  not need  regular maintenance.) 
Replacing  Restraint  System Parts 
After a Crash 
A crash  can  damag  he  restrain . :ems in 
your  vehicle. 
A damaged  restraint  system  may 
not  properly  protect  the  person  using 
it, 
resulting in serious  injury  or  even  death  in  a 
crash. 
To help  make  sure  your  restraint 
systems  are  working  properly  after  a  crash, 
have  them  inspected  and  any  necessary 
replacements  made  as 
soon as  possible.
