Dolly Towing - GMC 2009 Envoy Denali Owner's Manual

CAUTION:
{
Shifting a four-wheel-drive vehicle's transfer case
into N (Neutral) can cause the vehicle to roll even if
the transmission is in P (Park). The driver or others
could be injured. Make sure the parking brake
is firmly set before the transfer case is shifted to
N (Neutral).
5. Shift the transfer case to Neutral. See "Shifting into
Neutral" under Four-Wheel Drive on page 2-28.
6. Release the parking brake only after the vehicle
being towed is firmly attached to the towing vehicle.
7. Turn the ignition to LOCK/OFF and remove the
key — the steering wheel will still turn.
After towing, see "Shifting Out of Neutral" under
Four-Wheel Drive on page 2-28.
