Rear  Window  Washer/Wiper 
To turn the rear  wiper on, slide the switch to either LO 
or HI. To turn  the  wiper off, slide the switch to OFF. 
To wash the window, press  the  wash  button located on 
the switch. 
The  rear window  washer uses the same  fluid  bottle as 
the windshield  washer. However, 
the rear  window 
washer  will 
run out  of fluid  before  the windshield 
washer. 
If you can wash your  windshield but not your 
rear  window,  check your fluid  level. 
Cruise Control 
With cruise control,  you can 
maintain 
a speed of about 
25 mph (40 kdh) or more 
without keeping  your  foot 
on the accelerator. This can 
really help  on long  trips. 
Cruise control  does not 
work  at speeds  below about 
25 mph (40 kdh). 
If you apply your brakes, the cruise control  will shut off. 
0 Cruise  control  can  be  dangerous  where  you 
can’t  drive  safely at 
a steady  speed. So, 
don’t  use  your  cruise  control on winding 
roads 
or in  heavy  traffic. 
slippery  roads.  On  such  roads,  fast  changes  in  tire  traction  can  cause  needless  wheel 
spinning,  and  you  could  lose  control.  Don’t 
use  cruise  control 
on slippery  roads.

Remember:  Anti-lock  doesn’t  change  the  time  you  need 
to  get  your  foot  up  to  the  brake  pedal  or  always  decrease  stopping  distance.  If  you  get  too  close  to  the  vehicle  in 
front 
of you,  you  won’t  have  time  to  apply  your  brakes 
if  that  vehicle  suddenly  slows 
or stops.  Always  leave 
enough  room  up  ahead  to  stop,  even  though  you  have 
anti-lock  brakes. 
Using Anti-Lock 
Don’t  pump  the  brakes.  Just  hold  the  brake  pedal  down firmly  and  let  anti-lock  work  for  you.  You  may feel  the 
brakes  vibrate,  or  you  may  notice  some  noise,  but  this 
is  normal. 
Braking in Emergencies 
With  anti-lock,  you  can  steer  and  brake  at  the  same 
time.  In  many  emergencies,  steering  can  help  you  more  than  even 
the very  best  braking. 
Steering 
Power  Steering 
If  you lose  power  steering  assist  because  the  engine 
stops  or  the  system  is  not  functioning,  you  can  steer  but 
it  will  take  much  more  effort. 
Steering  Tips 
Driving on Curves 
It’s  important  to  take  curves  at  a  reasonable  speed. 
A  lot  of the  “driver  lost  control”  accidents  mentioned  on 
the  news  happen  on  curves.  Here’s  why: 
Experienced  driver  or  beginner,  each  of  us is  subject  to 
the  same  laws  of physics  when  driving  on  curves.  The 
traction  of the  tires  against  the  road  surface  makes  it 
possible  for  the  vehicle  to  change  its  path  when  you 
turn 
the  front  wheels. If there’s  no  traction,  inertia  will  keep 
the  vehicle  going  in  the  same  direction.  If you’ve  ever 
tried  to  steer  a  vehicle  on  wet  ice,  you’ll  understand  this.

The traction YOLI can  get in a curve depends on the 
condition  of your  tires and 
the road  surface,  the  angle  at 
which  the  curve is  banked,  and  your  speed. While you’re 
in a curve,  speed is the one factor  you  can control. 
Suppose you’re steering  through 
a sharp curve. Then you 
suddenly  accelerate.  Both  control  systems 
-- steering and 
acceleration 
-- have to do  their  work  where the  tires  meet 
the  road.  Adding the  sudden  acceleration  can  demand  too 
much 
of those  places.  You can  lose  control. 
What should  you do 
if this ever  happens? Ease up on the 
accelerator pedal,  steer the vehicle the  way  you  want 
it 
to go, and slow down. 
Speed 
limit signs  near curves  warn  that YOLI should 
adjust  your speed.  Of course,  the posted  speeds are 
based 
on good weather and  road conditions.  Under  less 
favorable conditions you’ll want to go slower. 
If you  need  to reduce your speed as you approach a 
curve,  do it before  you enter  the curve,  while your front 
wheels are straight  ahead. 
Try to adjust your speed so YOLI can “drive” through 
the  curve. Maintain  a  reasonable, steady speed.  Wait  to 
accelerate  until you are out  of the  curve, 
and then 
accelerate gently into  the straightaway. 
Steering  in Emergencies 
There are times  when steering can  be more effective 
than  braking.  For example,  you come over  a hill  and 
find a truck  stopped in your lane,  or  a car suddenly pulls 
out from  nowhere,  or 
a child darts out  from between 
parked  cars and stops right 
in front of you.  You can 
avoid these  problem by braking 
-- if you  can stop in 
time.  But sometimes  you can’t;  there isn’t room. 
That’s 
the time for evasive action -- steering around 
the  problem. 
Your  vehicle  can perform  very  well 
in emergencies like 
these.  First apply  your brakes.  (See  “Braking 
in 
Emergencies” earlier in this section.) Tt is better to 
mmve  as much  speed 
as you can from a possible 
collision.  Then steer around  the problem, to the left  or 
right  depending  on the  space available.

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. 
Skidding 
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. 
111 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, 
c gravel  or other  material  is  on the road.  For safety, you'll 
want  to slow  down 
and ad-just  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 OF 
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.

Controlling your vehicle is the  key to successful 
off-road  driving. One  of the  best  ways 
to control your 
vehicle 
is to control your  speed. Here are some things  to

keep in mind.  At higher  speeds: 
- 
you approach things  faster and you  have less time 
to  scan 
the terrain for  obstacles. 
you  have less time  to react. 
you  have more vehicle bounce  when  you drive 
over obstacles. 
you’ll  need more  distance  for  braking, especially 
since you’re on  an unpaved  surface. 
’ A CAUTION: 
When  you’re  driving off-road,  bouncing  and 
quick  changes  in  direction can easily  throw  you 
out  of  position.  This  could  cause you  to  lose 
control  and  crash. 
So, whether you’re driving on 
or off the  road,  you  and  your  passengers should 
wear  safety  belts. 
Scanning the Terrain 
Off-road  driving  can  take  you  over  many  different  kinds 
of terrain.  You  need  to  be  familiar  with  the  terrain  and  its 
many  different  features.  Here  are  some  things 
to consider. 
Sutface Conditicm. Off-roading  can  take  you  over 
hard-packed  dirt,  gravel,  rocks,  grass,  sand,  mud,  snow  or 
ice.  Each  of  these  surfaces  affects  the  steering,  acceleration 
and  braking 
of your  vehicle  in  different  ways.  Depending 
upon  the  kind  of  surface you  are  on,  you  may  experience 
slipping,  sliding,  wheel  spinning,  delayed  acceleration, 
poor  traction  and  longer  braking  distances. 
Swfc/ce Ubstcrcles. Unseen  or hidden  obstacles  can  be 
hazardous. 
A rock,  log,  hole, rut or  bump  can  startle  you if 
you’re  not  prepared  for  them.  Often  these  obstacles  are 
hidden  by  grass,  bushes,  snow  or  even  the  rise  and  fall  of 
the  terrain  itself.  Here  are  some  things 
to consider: 
Is the  path  ahead  clear? 
0 Will the surface texture  change abruptly  up ahead? 
0 Does the travel take  you uphill or downhill?  (There’s 
more discussion  of these subjects later.) 
0 Will  you  have  to  stop suddenly  or  change 
direction quickly?

L 
Getting  out on the  downhill  (low) side of a vehicle 
stopped across  an incline  is dangerous.  If the 
vehicle  rolls  over,  you  could  be  crushed or killed. 
Always  get  out on the  uphill  (high)  side of the 
vehicle  and stay  well clear  of the  rollover path. 
Driving  in  Mud,  Sand,  Snow or Ice 
When you drive in mud,  snow  or  sand,  your  wheels  won’t 
get  good  traction.  You can’t  accelerate  as  quickly,  turning  is 
more  difficult,  and  you’ll  need  longer  braking  distances. 
It’s  best  to use 
a low  gear  when  you’re  in  mud -- the 
deeper  the  mud,  the  lower  the  gear.  In  really  deep  mud,  the 
idea  is  to  keep  your  vehicle  moving 
so you don’t  get  stuck. 
When  you  drive on sand,  you’ll sense 
a change in wheel 
traction.  But 
it will depend upon  how loosely packed  the 
sand  is. On loosely packed sand  (as on beaches 
or sand 
dunes)  your tires  will tend to sink into  the sand.  This has 
an effect on  steering, accelerating and braking.  You may 
want 
to reduce the air pressure in your tires slightly 
when  driving on 
sand. This will improve traction.  Hard  packed  snow  and  ice  offer  the  worst  tire  traction.  On 
these  surfaces,  it’s  very  easy  to lose  control.  On  wet  ice,  for 
example,  the  traction  is 
so poor  that  you will have  difficulty 
accelerating.  And 
if you  do get  moving,  poor  steering  and 
difficult  braking  can  cause  you  to  slide  out 
of control. 
Driving  on frozen lakes, ponds  or  rivers can be 
dangerous.  Underwater  springs,  currents  under 
the  ice,  or sudden  thaws can  weaken the ice.  Your 
vehicle  could fall through  the  ice and  you and 
your passengers  could drown.  Drive your vehicle 
on  safe  surfaces  only. 
Driving in Water 
Light  rain  causes no special off-road  driving problems. 
But  heavy  rain  can mean  flash flooding, and flood 
waters demand extreme  caution. 
Find  out how  deep  the water  is before  you drive  through 
it. If it’s deep  enough to cover your  wheel hubs, axles  or 
exhaust pipe, don‘t 
try it -- you  probably won’t get 
through. Also.  water that deep  can damage your axle 
and  other vehicle parts.

I 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 
(if  you  have one).  It 
was developed  for use  on 
your  vehicle. 
A CAUTION: 
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. 
ProCarManuals.com 
Page 284 of 380

Treadwear 
The treadwear grade  is a comparative rating  based on 
the wear rate  of the tire when tested under controlled 
conditions  on a specified government  test course.  For 
example, 
a tire graded 150 would wear one and  a half 
(1 1/2) times  as  well on the government  course as a tire 
graded 
100. The  relative  performance of tires depends 
upon the actual  conditions  of their use, however,  and 
may  depart significantly from the  norm due 
to variations 
in  driving  habits, service practices  and differences 
in 
road characteristics  and climate. 
Traction -- A, B, C 
The  traction grades, from  highest  to lowest, are 
A, B, and C, and they represent the tire’s ability  to  stop 
on wet pavement as measured under controlled 
conditions  on specified government  test surfaces  of 
asphalt and  concrete. 
A tire marked C may  have poor 
traction performance. 
Warning:  The traction grade assigned  to this tire  is  based 
on braking  (straight  ahead)  traction tests and does  not 
include cornering  (turning) traction. 
Temperature -- A, B, C 
The temperature grades  are A (the highest), B, and C, 
representing the tire’s resistance  to the generation of 
heat  and its ability  to dissipate  heat  when  tested under 
controlled conditions 
on a  specified indoor laboratory 
test  wheel. Sustained  high temperature can cause 
the 
material  of  the  tire to degenerate  and reduce  tire life, and 
excessive temperature 
can lead  to  sudden  tire failure. 
The  grade 
C corresponds to a level  of performance 
which all passenger  car tires  must  meet  under  the 
Federal Motor  Vehicle Safety Standard 
No. 109. Grades 
B and A represent higher levels of performance on the 
laboratory  test  wheel than the minimum required  by  law. 
Warning:  The temperature grade 
for this tire is 
established for a tire  that  is properly  inflated and  not 
overloaded. Excessive speed, underinflation,  or 
excessive loading, either separately 
or in combination, 
can cause  heat buildup and possible  tire failure.
