Remote Vehicle Start

~2min read

If available, this feature allows you to start the engine from outside of the vehicle. It may also start up the vehicle's heating or air conditioning systems and rear window defogger.

Normal operation of the system will return after the key is turned to the ON/RUN position.

If the vehicle has an automatic climate control system, the climate control system will default to a heating or cooling mode depending on the outside temperatures. If the vehicle does not have an automatic climate control system, the system will turn on at the setting the vehicle was set to when the vehicle was last turned off.

During a remote start, if the vehicle has an automatic climate control system and heated seats, the heated seats will turn on during colder outside temperatures and will shut off when the key is turned to ON/RUN. If the vehicle does not have an automatic climate control system, during remote start, manually turn the heated seats on and off. See Heated and Ventilated Front Seats on page 3‑9 for additional information.

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 the vehicle is low on fuel. The vehicle may run out of fuel.

If the vehicle has the remote start feature, the RKE transmitter functions will have an increased range of operation. However, the range may be less while the vehicle is running.

There are other conditions which can affect the performance of the transmitter. See Remote Keyless Entry (RKE) System on page 2‑2 for additional information.
