Extending Engine Run Time
For a 10-minute extension, repeat Steps 1 and 2 while the engine is still running. The remote start can only be extended once.
When the remote start is extended, the second 10-minute period will start immediately.
For example, if the vehicle has been running for five minutes, and 10 minutes are added, the engine will run for a total of 15 minutes.
A maximum of two remote starts, or a remote start with an extension, are allowed between ignition cycles.
The vehicle's ignition must be changed to ON/RUN/START and then back to OFF before the remote start procedure can be used again.
