GMC 2009 Sierra - Manual (Page 81)

Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked from
about 3 feet (1 m) up to 65 feet (20 m) away with
the Remote Keyless Entry (RKE) transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the RKE transmitter. The RKE
transmitter, with the remote start button, provides
an increased operating range of 195 feet (60 m) away.
However, the operating range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off than you were
to start it.
There are other conditions which can affect the
performance of the transmitter. See Remote Keyless
Entry (RKE) System on page 2-4.

(Remote Vehicle Start): If your vehicle has this
feature, press
