Automatic Transmission Operation - GMC YUKON DENALI 2000 Manual

Automatic Transmission Operation

There are several different positions for your shift lever.
Your vehicle features an electronic shift position indicator
within the instrument cluster. This display must be
powered anytime the shift lever is capable of being moved
out of PARK (P). This means that if your key is in OFF,
rather than LOCK, there will be a small current drain on
your battery which could discharge your battery over a
period of time. If you need to leave your key in the
ignition in OFF for an extended period for any reason, it is
recommended that you disconnect the battery cable from
the battery to prevent discharging your battery.
PARK (P): This locks your rear wheels. It's the best
position to use when you start your engine because your
vehicle can't move easily.
2-26
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.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See "Shifting Into PARK (P)" in the Index. If you
-
have four wheel drive, your vehicle will be free to
--
