Parking on Hills 
You really should  not  park  your  vehicle,  with a trailer 
attached,  on 
a hill. If something  goes  wrong,  your  rig 
could  start  to move.  People  can  be injured,  and  both 
your  vehicle  and  the trailer can  be damaged. 
But 
if you  ever  have  to  park  your rig on a  hill,  here’s 
how  to  do it: 
1.  Apply  your regular  brakes, but don’t  shift into 
PARK  (P) yet. 
2. Have someone  place chocks  under  the  trailer  wheels. 
3. When  the wheel  chocks are in  place,  release  the 
regular  brakes  until  the chocks  absorb  the  load. 
4. Reapply  the regular  brakes. Then apply  your parking 
brake,  and  then  shift  to 
PARK (P). 
5. Release the  regular  brakes. 
When You Are  Ready to Leave  After 
Parking 
on a  Hill 
1.  Apply  your regular  brakes  and  hold the pedal down 
while  you: 
Start  your engine; 
Shift into  a gear;  and 
Release the parking  brake. 
2. Let up on the  brake  pedal. 
3. Drive  slowly  until  the trailer is clear  of the chocks. 
4. Stop  and have someone pick  up  and store the chocks. 
Maintenance  When  Trailer  Towing 
Your vehicle  will  need  service  more  often  when  you’re 
pulling  a  trailer.  See  the  Maintenance  Schedule  for  more 
on this. Things that  are  especially  important in trailer 
operation  are  automatic  transaxle  fluid  (don’t  overfill), 
engine 
oil, belts, cooling system,  and  brake  adjustment. 
Each 
of these is covered in this  manual,  and  the Index will 
help  you  find  them  quickly. If you’re  trailering,  it’s  a  good 
idea 
to review  these  sections  before  you start your trip. 
Check  periodically to see that all hitch nuts  and  bolts 
are  tight.

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. 
These  grades 
are molded  on  the sidewalls  of  passenger 
car  tires. 
While 
the tires  available  as  standard  or  optional 
equipment  on General Motors  vehicles 
may vary  with 
respect  to these  grades,  all  such tires  meet  General 
Motors  performance  standards and have  been  approved 
for  use  on  General  Motors  vehicles. All  passenger  type 
(P Metric)  tires  must  conform to Federal  safety 
requirements  in addition to  these  grades. 
Wheel Alignment  and  Tire  Balance 
The wheels  on  your  vehicle were aligned  and balanced 
carefully  at 
the factory  to give  you the longest  tire life 
and  best  overall  performance. 
In  most  cases,  you  will  not need  to  have  your wheels 
aligned  again.  However,  if 
you notice unusual  tire wear 
or  your  vehicle  pulling  one way  or the  other,  the 
alignment  may  need  to  be reset.  If  you  notice your 
vehicle  vibrating  when  driving on a smooth road, your 
wheels  may  need to be  rebalanced. 
Wheel  Replacement 
Replace  any wheel  that is bent, cracked,  or badly  rusted 
or  corroded. 
If wheel  nuts  keep coming  loose,  the  wheel, 
wheel  bolts,  and  wheel nuts should  be replaced. 
If the 
wheel  leaks  air,  replace it (except some aluminum 
wheels,  which  can sometimes  be  repaired).  See 
your 
Pontiac  dealer if any of these conditions exist. 
Your  dealer  will  know  the  kind 
of wheel you need. 
Each  new  wheel  should  have the same load carrying 
capacity,  diameter,  width,  offset,  and  be mounted the 
same  way 
as the  one it replaces.

If you  need  to replace any of your  wheels,  wheel  bolts, 
or wheel  nuts,  replace them  only  with  new GM original 
equipment  parts. This  way,  you  will  be  sure 
to have the 
right  wheel,  wheel  bolts,  and  wheel  nuts for your 
Pontiac  model. 
NOTICE: 
The  wrong  wheel can  also  cause  problems  with 
bearing  life, brake  cooling,  speedometer/odometer 
calibration,  headlamp  aim,  bumper  height, vehicle 
ground  clearance,  and  tire  or tire  chain  clearance 
to the  body  and chassis.  Used 
Replacement  Wheels 
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  wheeIs 
with  chains  on  will damage  your  vehicle.
