3. If it is the first remote start since the vehicle has
been driven, repeat these steps, while the engine
is still running, to extend the engine running time
by 10 minutes. Remote start can be extended
one time.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.
If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has
been done.
To manually shut off a remote start:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning flashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the first 10 minute remote start time
frame, and before the engine stops.
3-8
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 ten minutes are considered a second
remote vehicle 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 remote started again.
The vehicle cannot be remote started 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 vehicle
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. See REMOTE START
under DIC Vehicle Customization on page 4 60 for
additional information. If your vehicle does not have DIC
buttons, see your dealer to enable or disable the remote
vehicle start system.
