Then, see if you can move the shift
lever away from P (Park) without
rst pressing the shift lever button.
If you can, it means that the
shift lever was not fully locked into
P (Park).
Torque lock is when the weight of
the vehicle puts too much force
on the parking pawl in the
transmission. This happens when
parking on a hill and shifting
the transmission into P (Park) is
not done properly and then it
is difficult to shift out of P (Park).
To prevent torque lock, set the
parking brake and then shift into
P (Park). To nd out how, see
“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so
you can shift out of P (Park).Shifting Out of Park
(Automatic
Transmission)

How OnStar Service Works
The OnStar system can record
and transmit vehicle information.
This information is automatically
sent to an OnStar Call Center when
the OnStar button is pressed, the
emergency button is pressed,
or if the airbags or AACN system
deploy. This information usually
includes the vehicle’s GPS location
and, in the event of a crash,
additional information regarding
the crash that the vehicle was
involved in (e.g. the direction from
which the vehicle was hit). When the
Virtual Advisor feature of OnStar
Hands-Free Calling is used,
the vehicle also sends OnStar the
vehicle’s GPS location so they
can provide services where
it is located.
Features and Controls 2-41

OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless the vehicle is in
a place where the wireless service
provider OnStar has hired for
that area has coverage, network
capacity and reception when
the service is needed, and
technology that is compatible
with the OnStar service. Not all
services are available everywhere,
particularly in remote or enclosed
areas, or at all times.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannotcontrol that may prevent OnStar
from providing OnStar service at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.
