Loss of Control 
Let’s review  what driving  experts say about  what 
happens  when the  three  control systems (brakes,  steering 
and  acceleration)  don’t  have enough friction where the 
tires meet the road  to  do what the  driver  has  asked. 
In any  emergency,  don’t  give  up.  Keep  trying  to  steer  and 
constantly  seek  an  escape  route  or area  of less  danger. 
In 
a skid,  a driver can lose control  of the  vehicle. 
Defensive  drivers  avoid  most  skids  by taking  reasonable 
care  suited  to existing  conditions,  and by not  “overdriving” 
those  conditions.  But  skids  are always  possible. 
The  three  types 
of skids  correspond  to your vehicle’s 
three  control  systems.  In the  braking  skid,  your wheels 
aren’t  rolling.  In  the steering  or  cornering  skid,  too 
much speed  or  steering in a curve  causes  tires to  slip  and 
lose  cornering  force.  And  in the acceleration  skid, 
too 
much throttle  causes  the  driving  wheels to spin. 
A cornering skid and an  acceleration  skid  are  best 
handled  by easing  your foot off the  accelerator  pedal. 
If your vehicle  starts to slide,  ease  your foot off the 
accelerator  pedal  and quickly steer 
the way  you want the 
vehicle  to go. 
If you  start  steering quickly enough, your 
vehicle  may straighten  out. Always  be ready  for a 
second  skid if it occurs. 
Of course,  traction is reduced when water, snow, ice, 
gravel  or  other  material is on the road. For safety, you’ll 
want  to slow down and  adjust your driving  to these 
conditions.  It  is  important  to  slow down on slippery 
surfaces  because  stopping distance will be longer and 
vehicle  control  more limited. 
While  driving  on a surface  with reduced traction,  try 
your  best to avoid  sudden steering,  acceleration  or 
braking  (including  engine braking by  shifting to a lower 
gear).  Any sudden changes  could  cause  the tires to slide. 
You  may  not  realize 
the surface is slippery until your 
vehicle  is  skidding.  Learn to  recognize  warning 
clues 
-- such  as enough water,  ice  or packed snow  on 
the  road  to make a “mirrored surface” 
-- and slow 
down when you have any  doubt. 
Remember:  Any anti-lock  brake system 
(ABS) helps 
avoid only the braking  skid.

Total  Weight on Your Vehicle’s  Tires 
Be sure your vehicle’s tires  are  inflated  to the upper 
limit  for  cold tires.  You’ll find these  numbers on the 
CertificatiordTire label  at the  rear  edge  of the  driver’s 
door  or 
see “Tire Loading”  in  the Index. Then be  sure 
you don’t 
go over  the GVW limit  for  your vehicle, 
including the weight  of the trailer tongue. 
Hitches 
It’s  important  to  have the  correct  hitch equipment. 
Crosswinds, large trucks going  by and rough roads are a 
few  reasons  why you’ll need the right hitch. Here  are 
some rules  to follow: 
If you’ll  be pulling a trailer that, when loaded,  will 
weigh more than 
2,000 lbs. (900 kg), be  sure  to  use a 
properly mounted, weight-carrying hitch and sway 
control  of the proper size.  This equipment  is very 
important  for proper  vehicle  loading and  good 
handling when you’re driving. 
Will  you  have to make any  holes in the  body  of  your 
vehicle when  you install a trailer hitch? 
If  you  do, then  be  sure  to seal the holes later when 
you  remove the hitch.  If  you don’t seal them, deadly 
carbon monoxide 
(CO) from your exhaust can  get 
into your vehicle (see “Carbon Monoxide” in the 
Index). Dirt and water  can, too. 
The bumpers on your vehicle  are not intended for 
hitches. Do not attach  rental hitches  or  other 
bumper-type  hitches 
to them.  Use only a 
frame-mounted  hitch that does not attach 
to 
the  bumper.

11. Remove the cables in reverse  order  to  prevent 
electrical shorting. Take  care that they  don’t touch 
each other  or any other metal.

Towing Your Vehicle 
Try  to have a GM  dealer or a professional towing 
service  tow your vehicle. They  can provide the right 
equipment and 
know how  to tow  it without damage. See 
“Roadside Assistance”  in the Index. 
If  your vehicle has been changed  or modified  since 
it 
was factory-new  by adding aftermarket items like  fog 
lamps, aero skirting, or special tires and wheels, these 
things can be damaged during towing. 
Before  you do anything, turn 
on the hazard 
warning flashers. 
When  you  call, tell the towing service: 
That your vehicle has front-wheel  drive. 
That your vehicle cannot  be towed  from the front  or 
rear with sling-type  equipment. 
0 The  make, model and  year  of your vehicle. 
Whether  you can still move the shift  lever. 
0 If there  was an accident, what was damaged.

Inflation -- Tire  Pressure 
The  CertificatiodTire  label, which is on the rear edge of 
the  driver’s  door, shows the correct inflation pressures 
for  your tires when they’re  cold. “Cold” means your 
vehicle has been sitting for at  least  three hours or driven 
no more than 
1 mile ( 1.6  km). 
NOTICE: 
Don’t  let  anyone  tell  you that  underinflation  or 
overinflation  is all  right.  It’s  not. 
If your  tires 
don’t  have  enough  air  (underinflation),  you can 
get  the  following: 
0 Too much  flexing 
Too much  heat 
0 Tire  overloading 
Bad  wear 
0 Bad  handling 
0 Bad  fuel  economy. 
NOTICE:  (Continued)  NOTICE:  (Continued) 
If your  tires  have  too  much  air  (overinflation), 
you  can  get  the  following: 
0 Unusual  wear 
0 Bad  handling 
Rough  ride 
0 Needless damage  from  road  hazards. 
When  to  Check 
Check your tires once  a month  or more. 
Don’t forget your compact  spare tire. 
It should be  at 
60  psi 
(420 kPa). 
How  to  Check 
Use  a good quality pocket-type  gage  to check tire 
pressure. 
You can’t tell  if your  tires  are  properly inflated 
simply  by looking at them. Radial tires  may look 
properly inflated even when  they’re underinflated. 
Be  sure  to put the valve  caps back  on the valve 
stems.  They help prevent  leaks by keeping  out dirt 
and moisture.

When It’s Time for New Tires 
One way to tell when  it’s 
time  for  new tires  is to 
check the treadwear 
indicators, which  will 
appear  when your tires have 
only 
1/16 inch (1.6 mm)  or 
less  of tread remaining. 
You need  a new  tire if any  of  the following statements 
are  true: 
You  can see the indicators  at three  or  more places 
around the tire. 
You can  see  cord  or  fabric  showing through the 
tire’s  rubber. 
The  tread  or  sidewall  is cracked,  cut  or snagged deep 
enough to show cord  or  fabric. 
The tire has a bump, bulge  or  split. 
The tire has a puncture,  cut or other damage that 
can’t  be repaired  well because 
of the size  or location 
of the damage. 
Buying New Tires 
To  find out what kind and  size of tires  you need, look 
at the  CertificatiodTire  label. 
The tires installed on your vehicle when  it was  new  had 
a  Tire  Performance Criteria Specification (TPC  Spec) 
number 
on each  tire’s  sidewall. When  you get new  tires, 
get ones  with that same  TPC Spec number.  That way 
your vehicle  will continue  to  have tires that  are designed 
to give proper endurance, handling, speed rating, 
traction,  ride and other things  during normal service  on 
your vehicle.  If your tires have an all-season tread 
design, the TPC number  will  be followed  by an “MS” 
(for  mud  and  snow). 
If you ever replace your tires with those  not having  a 
TPC  Spec number, make  sure they  are the  same size, 
load range, speed rating and construction type (bias, 
bias-belted  or radial) as your original tires.

CAUTION: 
Mixing tires could  cause  you  to lose  control  while 
driving. 
If you mix tires  of different  sizes or types 
(radial  and  bias-belted  tires),  the vehicle  may  not 
handle  properly,  and you  could  have  a  crash. 
Using  tires of different  sizes  may  also  cause 
damage to your  vehicle.  Be sure to use  the same 
size  and  type  tires  on all wheels. 
It’s  all  right to drive  with your  compact  spare, 
though.  It was  developed  for use  on  your vehicle. 
i A CAUTION: I 
I If you  use  bias-ply  tires on your  vehicle,  the 
wheel  rim flanges  could  develop  cracks  after 
many  miles  of driving. 
A tire  and/or  wheel  could 
fail  suddenly,  causing  a  crash. Use  only  radial-ply 
tires  with  the wheels 
on your  vehicle. 
Uniform  Tire  Quality  Grading 
The  following  information  relates  to the system 
developed  by the  United  States  National  Highway 
Traffic Safety  Administration,  which grades tires by 
treadwear, traction and temperature performance.  (This 
applies  only to vehicles sold  in  the United States.)  The 
grades  are molded  on the  sidewalls 
of most  passenger 
car  tires.  The  Uniform Tire Quality Grading  system 
does not apply  to deep  tread,  winter-type  snow  tires, 
space-saver  or temporary  use spare  tires, tires with 
nominal  rim  diameters  of 
10 to 12 inches (25 to 30 cm), 
or  to  some  limited-production  tires. 
While  the  tires  available  on General Motors passenger 
cars  and light  trucks may  vary  with respect to these 
grades,  they must also conform  to Federal  safety 
requirements  and additional  General Motors  Tire 
Performance  Criteria 
(TPC) standards.

Used Replacement  Wheels 
I * I 
1 
Putting a used wheel  on  your  vehicle  is 
dangerous.  You can’t  know  how it’s been  used  or 
how  far it’s been  driven.  It could  fail  suddenly 
and  cause  an  accident.  If you have  to  replace  a 
wheel,  use 
a new GM original  equipment  wheel. 
Tire Chains 
NOTICE: 
Use tire  chains  only where  legal and only  when 
you  must.  Use only 
SAE Class “S” type  chains 
that  are  the  proper  size for  your  tires.  Install 
them  on  the  front  tires  and  tighten  them  as 
tightly  as  possible  with  the  ends  securely 
fastened.  Drive  slowly and follow  the  chain 
manufacturer’s  instructions.  If you  can  hear  the 
chains  contacting  your  vehicle, stop  and  retighten 
them. 
If the  contact  continues,  slow down  until  it 
stops.  Driving  too  fast  or  spinning  the  wheels 
with  chains  on  will damage  your  vehicle.
