impact more evenly  over  the occ.upant’s upper body, stopping the occupant 
more gradually. But  air bags  would  not  help you 
in many types  of collisions, 
including rollovers  and rear and side impacts, primarily because  an 
occupant’s  motion 
is not toward the  air bag. Air bags should never  be 
regarded 
as anything more than a supplement  to safety belts,  and then only 
in moderate  to severe frontal  or near-frontal  collisions. 
What will you  see  after  an  air  bag  inflates? 
After the air bag  inflates, it quickly deflates.  This  occurs so quickly that 
some  people  may  not  even realize  the air bag  inflated.  Some  components  of 
the  air bag module 
in the  steering  wheel  hub will be hot for  a short time, but 
the part  of the  bag  that  comes  into  contact with  you  will  not  be  hot to the 
touch.  There will  be  some smoke 
and dust coming  from vents in the deflated 
air bag.  Air  bag inflation 
will not prevent  the driver from seeing or from 
being  able to steer  the vehicle, nor 
will it stop  people  from leaving  the 
vehicle. 
A CAUTION: 
When  an air  bag  inflates,  there  is  dust  in  the  air.  This  dust  could 
cause  breathing  problems  for  people  with 
a history  of  asthma  or 
other  breathing  trouble.  To avoid  this,  everyone  in  the  vehicle 
should  get  out  as  soon  as  it 
is safe  to  do so. If  you  have  breathing 
problems  but  can’t  get  out  of  the  vehicle  after  an  air  bag\
  inflates, 
then  get  fresh  air 
by opening  a  window  or door.

The  air  bag  is designed  to inflate only  once. After it inflates, you’ll 
need  some  new parts  for your air  bag system. 
If you  don’t get them,  the 
air 
bag system  won’t  be  there to help protect you in another crash.  A 
new  system 
will include the air bag  module  and possibly other parts. 
The  service  manual for your  vehicle  covers the need  to replace  other 
parts. 
Your vehicle is equipped with a diagnostic module,  which records 
information  about  the air bag system.  The module records information 
about the readiness  of the  system,  when 
the sensors are activated  and 
driver’s  safety belt usage  at deployment. 
Let  only qualified technicians work on your  air bag  system.  Improper 
service  can mean  that your  air bag  system won’t  work properly.  See 
your dealer  for  service.

Larger Children 
Children  who  have  outgrown  child  restraints  should  wear  the  vehicle’s 
safety  belts.

wear  a  lap-shoulder  belt  and  get  the  additional  restraint

A CAUTION: 
Leaving  young  children  in  a vehicle  with  the  ignition  key  is 
dangerous  for  many  reasons. 
A child  or  others  could  be  badly 
injured 
or even  killed. 
They  could  operate  power  windows  or  other  controls 
or even 
make  the  vehicle  move.  Don’t  leave  the  keys  in  a vehicle  with 
young children.

Key in the Ignition 
If you  walk away from  your vehicle  with the keys  inside, it’s an easy target 
for  joy  riders  or professional  thieves 
- so don’t do it. 
When  you park your vehicle and open the  driver’s door, you‘ll  hear a tone 
reminding 
you to  remove  your  key from  the ignition and take it with  you. 
Always  do  this. 
Your steering  wheel will be locked,  and so will your 
ignition.  If  you have 
an automatic  transmission,  taking your key out also 
locks your transmission.  And remember  to lock the  doors. 
Parking at Night 
Park in a lighted  spot,  close  all windows and  lock your vehicle.  Remember 
to  keep 
your valuables  out of sight.  Put them in a storage  area,  or take them 
with 
you. 
Parking  Lots 
If you  park in a lot where  someone  will be watching your vehicle,  it‘s  best 
to  lock 
it up  and take  your  keys.  But what if you have to leave your ignition 
key?  What  if 
you have to leave  something valuable in your  vehicle? 
Put your valuables  in a storage area, like your  glove  box. 
Lock all the  doors  except the driver’s. 
New  Vehicle  “Break-In ” 
NOTICE: 
Your  modern  vehicle doesn’t  need  an  elaborate  “break-in.” But 
it  will  perform  better  in  the  long  run  if you  follow  these 
guidelines: 
Keep  your  speed  at 55 mph (88 km/h)  or  less for  the  first 500 
miles (804 km). 
Don’t  drive  at  any one speed - fast  or  slow - for the  first 
500  miles 
(804 km).  Don’t  make  full-throttle  starts. 
Avoid making  hard  stops  for  the  first 200 miles (322 km)  or 
so. During  this  time  your  new  brake  linings  aren’t  yet  broken 
in.  Hard  stops  with  new linings  can  mean  premature  wear  and 
earlier  replacement.  Follow  this  “breaking-in”  guideline 
every time  you  get  new brake  linings. 
Don’t tow a trailer  during  “break-in.” See  “Towing a Trailer” 
in  the  Index 
for more  information.

New Vehicle “Break-In” - 3500 HD Model 
If you have a 3500 HD model, your parking brake requires a special 
break-in  procedure.  See “Parking  Brake” 
in the Index. 
Ignition Switch 
Use  your  key to start your  vehicle.  The key lets you turn the ignition switch 
to  five  different positions: 
2 
5 
1. OFF 
2. RUN 
3. START 
4. ACC 
5. LOCK 
ACC  (Accessory): 
ACC lets you use things like the radio, power  windows 
and the windshield  wipers when the engine is off. To get into ACC, push in 
the key and turn it toward you.  Your steering  wheel  will  remain locked,  just 
as it was before you inserted  the key. 
LOCK: This  position  locks your ignition,  steering wheel and  transmission. 
It’s 
a theft deterrent  feature. You will only  be able  to remove  your key  when 
the ignition 
is turned  to LOCK. 
OFF: This position  lets  you turn  off the  engine  but still  turn the steering 
wheel.  It  doesn’t lock the  steering wheel like  LOCK. Use 
OFF if  you must 
have  your  vehicle 
in motion while the  engine is off (for example, if your 
vehicle  is  being pushed). 
RUN: This is the position  for  driving. 
START:  This  starts  your engine.
