Chevrolet Uplander Owner's Manual page 114

If the power sliding door has been manually locked,
you must unlock the PSD before it can be opened.
Notice: If you leave the power sliding door on when
you go through an automatic car wash, the door may
accidentally open. Be sure the power sliding door is
turned off when going through a car wash.
If the power sliding door(s) is open or in the process of
closing when you shift out of PARK (P), a chime will
sound. This is a warning that the sliding door(s) is not
completely closed. Also, the Driver Information
Center (DIC) will indicate if the door is open. See DIC
Warnings and Messages on page 3-51. Stop the vehicle
and close the door.
CAUTION:
{
If you shift the transaxle out of PARK (P) and
accelerate before the power sliding door
latches closed, the door may reverse to the
open position. A child or others could fall out
of the vehicle and be injured. Always make
sure the power sliding door is closed and
latched before you drive away.
2-20
If an object obstructs the power sliding door(s) while
it is closing, the door will automatically reverse to
the open position, provided it meets sufficient resistance.
Resistance must be as strong as the force of the
closing door, or stronger. The force of the closing door
increases significantly as the door approaches the
latched position.
The driver's side sliding door is designed to open only a
little if the fuel door is open. If this ever happens, do
not try to force the sliding door. When the fuel filler door
is closed, the driver's side sliding door can be opened
normally.
