The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the
remote start button is pressed and held again before
the rst 10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of the
engine run time, 10 minutes are added and you now
have 15 minutes of engine running. The added ten
minutes are considered a second remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
normally before the remote start feature can be used
again.
The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.

The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
