GMC 2008 Acadia - Manual (Page 91)

For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for five minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional 10 minutes are considered a second
remote start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key.
After the key is removed from the ignition, the vehicle
can be started using the remote start feature again.
The vehicle cannot be started using the remote
start feature if the key is in the ignition, the hood is not
closed, or if there is an emission control system
malfunction.
Also, the engine will turn off during a remote start if the
coolant temperature gets too high or if the oil pressure
gets low.
Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle
start system enabled. The system may be enabled or
disabled through the DIC if your vehicle has DIC
buttons. See “REMOTE START” under DIC Vehicle
Customization (With DIC Buttons) on page 3-75
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or
disable the remote start system.
Remote Start Ready
If your vehicle does not have the remote start feature, it
will have the remote start ready feature. This feature
allows your dealer/retailer to add the manufacturer’s
remote start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote start feature to your vehicle.
