Automatic Transmission Operation - Chevrolet 2008 Colorado Owner's Manual

Automatic Transmission Operation

It 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 turned off, but not in 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 but not in LOCK
for an extended period, it is recommended that you
disconnect the battery cable from the battery to prevent
discharging your battery.

Your automatic
transmission has
a shift lever on the
steering column.
There are several different positions for your shift lever.
PARK (P): This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot 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 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) (Automatic
Transmission) on page 2-34. If you are pulling
a trailer, see Towing a Trailer on page 4-47.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must
fully apply your regular brakes before you can
shift from PARK (P) when the ignition key is in ON.
