Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems, rear window defogger, and
heated seats. SeeHeated Seats on page 1-4and
Heated and Cooled Seats on page 1-5for additional
information. When the remote start system is active, the
climate control system will heat and cool the inside of
the vehicle based on the outside temperature. The rear
window defogger will be turned on by the climate
control system when it is heating the inside of the
vehicle. If the vehicle has heated seats, they may also
turn on. Cooled seats are not activated during a
remote start. Normal operation of the system will return
after the key is turned to the RUN position.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using the remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has remote start, the keyless entry
transmitter provides, an increased range of operation.
However, the range may be less while the vehicle
is running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-5for additional information.

then immediately press and hold the transmitter’s
remote start button until the turn signal lights
ash or if the vehicle’s lights are not visible, press
and hold the remote start button for at least
four seconds. The vehicle’s doors will lock. Pressing
the remote start button again after the vehicle
