GMC 2007 Envoy - Manual (Page 133)

{ CAUTION:
If your vehicle has four-wheel drive, it will
be free to roll — even if the shift lever is
in PARK (P) — if the transfer case is in
NEUTRAL. So be sure the transfer case is
in a drive gear — not in NEUTRAL. See
Four-Wheel Drive on page 122.
Follow the proper steps to be sure your vehicle
will not move. See Shifting Into Park (P) on
page 127.
If you are pulling a trailer, see Towing a Trailer on
page 362.
Mirrors
Manual Rearview Mirror
Your vehicle may have this feature. While sitting in
a comfortable driving position, adjust the rearview
mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up
or down and side to side. The day/night control,
located at the bottom of the mirror, adjusts
the mirror to reduce headlamp glare from behind
during evening or dark conditions. Turn the
control clockwise for night use; return it to the
center for daytime use.
