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.
