Automatic Transmission Operation - Hummer 2004 H2 Owner's Manual

Automatic Transmission Operation

Your vehicle is equipped with an automatic transmission
and features an electronic shift position indicator
located within the instrument panel cluster.
There are several different positions for your shift lever.
PARK (P): This position locks your drive wheels. It's
the best position to use when you start your engine
because your vehicle can't move easily.
CAUTION:
{
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
2-22

suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See Shifting Into Park (P) on
page 2-30. If you are pulling a trailer, see
Towing a Trailer on page 4-75.
CAUTION:
{
Your vehicle will be free to roll — even if your
shift lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the transfer
case is in a drive gear — not in NEUTRAL. See
Shifting Into Park (P) on page 2-30.
