Heavy snow  or ice can overload your wipers.  The windshield wiper motor  is 
protected  from overload  by 
a circuit breaker and  a  fuse. If the motor 
overheats  due  to heavy snow,  etc., the wiper will  stop 
until the motor cools. 
Although the circuit  is protected from electrical  overload, overload due 
to 
heavy  snow,  etc. may  cause wiper linkage damage.  Always  clear ice and 
heavy  snow from the windshield  before using your windshield wipers. 
Windshield Washer 
At the top of the  lever 
there’s  a paddle with 
the  word 
PUSH on it. 
To spray washer fluid 
on the windshield, 
push  the paddle. 
Washer fluid  will spray 
as long  as you  push  the paddle. When  you  let go of 
the paddle,  the wipers  will continue  to  wipe for a few seconds  and then 
either  stop 
or return to the preset  speed. 
Driving  without washer fluid  can  be dangerous. 
A bad  mud  splash can block 
your  vision.  You could 
hit another vehicle  or  go off the  road.  Check  your 
washer fluid level  often. 
A CAUTION: 
In  freezing  weather,  don’t  use  your  washer  until  the  windshi\
eld 
is  warmed.  Otherwise  the  washer 
fluid can form ice on the 
windshield,  blocking  your  vision.

NOTICE: 
When  using  concentrated  washer  fluid, follow the 
manufacturer’s  instructions  for  adding  water. 
0 Don’t  mix  water  with  ready-to-use  washer  fluid.  Water  can  cause  the  solution  to  freeze  and  damage  your  washer  fluid 
tank  and  other  parts  of the  washer  system. 
Also, water 
doesn’t  clean  as  well as  washer  fluid. 
0 Fill  your  washer  fluid  tank  only 3/4 full  when  it’s very  cold. 
This  allows  for  expansion,  which  could  damage  the  tank  if it is 
completely  full. 
Don’t  use  radiator  antifreeze  in  your  windshield  washer.  It 
can  damage  your  washer  system  and  paint. 
Cruise Control (Option) 
If you  have  Cruise 
Control,  the  end 
of 
your multifunction 
lever 
will look like 
this. 
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 kmk). 
When you apply your brakes, the Cruise  Control  shuts off.

When you want to leave  the freeway,  move to the  proper  lane  well  in 
advance.  If 
you miss your exit  do not,  under any  circumstances,  stop  and 
back  up. Drive  on 
to the next exit. 
The  exit ramp can  be curved,  sometimes  quite sharply. 
The 
exit speed is usually posted. 
Reduce  your speed according to your speedometer,  not to your sense 
of 
motion.  After driving  for any  distance  at higher  speeds,  you  may  tend to 
think  you are going  slower than you actually  are. 
Before  Leaving  on a Long  Trip 
Make sure you’re  ready.  Try to be well rested. If  you must start when  you’re 
not  fresh 
- such as after a day’s work - don’t  plan to make  too many 
miles that  first part 
of the journey.  Wear comfortable  clothing  and shoes  you 
can  easily drive 
in. 
Is your  vehicle ready for a long trip‘? If you keep it serviced  and maintained, 
it’s ready  to go. 
If it needs  service,  have it done before starting  out. Of 
course,  you’ll find experienced and able service  experts 
in GM dealers all 
across North America. They’ll be ready  and willing to help if you need it.

Windshield Washer Fluid: Is the reservoir  full? Are all windows  clean 
inside  and outside? 
Wiper  Blades: Are they in good shape? 
FueZ,  Engine  Oil,  Other  Fluids: Have you checked all levels? 
Lamps: Are they all working? Are the lenses  clean? 
Tires: They are vitally important to  a  safe, trouble-free  trip. Is the tread 
good enough  for long-distance  driving? Are 
the tires all inflated to the 
recommended  pressure? 
Weather Forecasts: What’s the weather  outlook along your  route? 
Should 
you delay your trip a short time to avoid  a major  storm  system? 
Maps: Do you have  up-to-date  maps? 
Highway  Hypnosis 
Is there  actually  such a condition as “highway hypnosis”?  Or  is  it just  plain 
falling  asleep  at the wheel? Call it highway  hypnosis, lack  of awareness,  or 
whatever. 
There 
is something  about an easy stretch  of road  with  the  same scenery, 
along  with the 
hum of the tires  on the road, the  drone of the engine,  and the 
rush 
of the wind against the vehicle that can make  you sleepy. Don’t  let  it 
happen 
to you! If it does,  your vehicle can leave the road  in less than a 
second, and  you could crash and  be injured.

Winter  Driving 
Here  are  some  tips  for winter driving: 
0 Have  your  vehicle in good shape  for  winter. Be sure  your  engine 
coolant  mix is correct. 
You may  want to put winter  emergency  supplies  in your  vehicle. 
Include  an ice  scraper,  a  small brush or broom,  a  supply  of windshield 
washer  fluid,  a  rag,  some  winter outer  clothing,  a  small  shovel, 
a flashlight, 
a  red  cloth,  and a  couple  of reflective  warning triangles.  And, if you  will  be 
driving  under  severe  conditions,  include  a  small  bag 
of sand,  a  piece of old 
carpet  or a  couple 
of burlap bags  to help  provide  traction. Be sure  you 
properly  secure 
these items  in your vehicle. 
Driving on Snow  or Ice 
Most of the  time,  those  places where  your  tires meet  the road probably  have 
good traction. 
However,  if there  is snow 
or ice  between  your  tires and the  road,  you can 
have  a  very  slippery  situation. You’ll have  a  lot  less  traction 
or “grip” and 
will  need  to  be  very careful.

Brake  Master  Cylinder 
Your  brake master  cylinder is here. It is filled with DOT-3 brake  fluid. 
There  are only two reasons  why  the brake fluid level 
in your master  cylinder 
might  go  down.  The first  is that the brake fluid goes down to  an acceptable 
level  during  normal brake lining  wear. When  new linings are put  in, the 
fluid level  goes back  up.  The  other  reason 
is that fluid  is leaking out of the 
brake  system. If it is, you should have your brake system  fixed, since a leak 
means that  sooner  or later your brakes won’t work well,  or won’t  work  at 
all. 
So, it isn‘t a good idea  to “top off’ your brake  fluid. Adding brake fluid 
won’t correct a leak. If  you  add fluid when your linings  are worn,  then 
you’ll  have 
too much fluid when  you get new  brake linings.  You should add

Care of  Safety  Belts 
Keep belts clean and dry. 
A CAUTION: 
Do not  bleach  or  dye  safety  belts.  If  you do, it may  severely 
weaken  them.  In  a  crash  they  might  not  be  able  to  provide 
adequate  protection.  Clean  safety  belts  only  with  mild  soap  and\
 
lukewarm  water. 
Glass 
Glass  should  be cleaned  often. GM  Glass  Cleaner (GM Part No. 1050427) 
or  a liquid household  glass  cleaner will remove  normal tobacco  smoke  and 
dust  films. 
Don’t  use abrasive  cleaners 
on glass,  because  they  may  cause  scratches. 
Avoid  placing  decals on the  inside  rear  window, since they may have to  be 
scraped  off later.  If abrasive  cleaners  are  used on the inside 
of the rear 
window,  an electric  defogger  element  may be damaged.  Any temporary 
license  should not be attached  across the defogger  grid. 
Cleaning  the  Outside of the Windshield  and 
Wiper  Blades 
If  the  windshield  is  not clear  after  using the windshield  washer,  or if the 
wiper blade  chatters when running,  wax or other  material  may  be on the 
blade  or windshield. 
Clean  the  outside  of the windshield  with GM Windshield Cleaner,  Bon-Ami 
Powder@  (GM 
Part No. 105001 1). The  windshield is clean if beads  do not 
form  when 
you rinse it with water. 
Clean 
the blade  by wiping vigorously  with a cloth soaked  in full strength 
windshield  washer solvent.  Then  rinse  the blade  with water. 
Wiper blades  should be  checked 
on a  regular basis and  replaced when worn. 
Weatherstrips 
Silicone  grease on weatherstrips  will make  them last longer, seal better, and 
not stick  or squeak.  Apply silicone  grease  with a  clean  cloth at least every 
six months.  During very cold,  damp  weather  more  frequent  application  may 
be  required.  (See  “Recommended  Fluids  and  Lubricants”  in the  Index.)
