Torque Lock
If you are parking on a hill and you
don’t shift your transaxle into P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle.
You may find it
difficult to pull the shift lever out of
P (Park). This is called “torque lock.”
To prevent torque lock, always be sure
to shift into
P (Park) properly before
you leave the driver’s seat. To find out
how, see the
lndex under Shifting Into
P (Park).
When you are ready to drive, move the
shift lever out
of P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours
a
little uphill to take some of the pressure
from the transaxle,
so you can pull the
shift lever out
of P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Pontiac in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow,
but they may give
you less traction on
ice than regular tires. If you do not
expect to be driving in deep snow, but
may have to travel over ice,
you may
not want to switch to snow tires at all.
.. “I
. ..
You may want to put winter
emergency supplies
in your trunk.
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.

Will the trailer brake parts take 3,000
psi (20 650 1tPa) of pressure? If not,
the trailer brake system must not be
used with your vehicle.
If everything checks out this far, then
make the brake fluid tap at the upper
rear master cylinder port. But don’t
use copper tubing for this. If you do,
it will bend and finally break
off. Use
steel brake tubing.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you’ll want to get
to know your rig. Acquaint yourself
with the feel of handling and braking
with the added weight of the trailer.
And always keep in mind that the
vehicle you are driving is now a good
deal longer and not nearly
so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, tires and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer
moving and then apply the trailer brake
controller by hand to be sure the brakes
are working. This lets
you check your
electrical connection at the same time.
During your trip, check occasionally to
be sure that the load is secure, and that
the lights and any trailer brakes are still
working.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without
a trailer.
This can help you avoid situations that
require heavy braking and sudden
turns.
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer.
And, because you’re a
good deal longer,
you’ll need to
go much farther beyond
the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move
the
trailer to the left, just move that hand to
the left.
To move the trailer to the right,
move your hand to the right. Always
back up slowly and, if possible, have
someone guide you.
