Extending Engine Run Time
To extend the engine run time by 10 minutes, repeat Steps 1 and 2 while the engine is still running.
The engine run time can only be extended if it is the first remote start since the vehicle has been driven.
Remote start can be extended one time.
If the remote start procedure is used again before the first 10-minute time frame has ended, the first 10 minutes will immediately expire and the second 10-minute time frame will start.
For example, if 
and then
are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for a total of
15 minutes.
A maximum of two remote starts or remote start attempts are allowed between ignition cycles.
After the vehicle's engine has been started two times using the remote start button, the ignition must be turned on and then back off before the remote start procedure can be used again.
