Remote Vehicle Start (RVS)

To operate the function, first press and release the lock button on the key fob, then press the remote vehicle start (RVS) button for 2 seconds. The vehicle park lamps will be illuminated to indicate that the engine is running. The vehicle doors will be able to be unlocked. The RVS function is allowed to start the vehicle 2 times for 10-minute intervals. If the body control module (BCM) receives a second request for an RVS event while already operating in RVS then the first timer times out and then the second timer starts. If the RVS button was pressed for the first time and then 7 minutes later the RVS button was pressed a second time, the total time for the RVS event would be 17 minutes. When the RVS button is pressed for the second time, the first 10-minute interval automatically stops and the BCM starts counting the second 10-minute interval. After the first event times out, 10 minutes, the second event must be requested within 20 minutes or the function is disabled.

RVS can be deactivated by pressing the RVS button on the key fob, pressing the hazard switch, or inserting the ignition key and cycling it to the ON position and then OFF again. There are also other safety and security measures that will deactivate RVS, these include depressing the accelerator pedal or opening the hood. RVS will not function with any current or history codes set. The park lights will flash once when the RVS signal is received by the BCM, but the vehicle will not start.

RVS is designed to transition for RVS to normal key ON, engine run operation without any apparent change to the customer except inserting the ignition key and turning it to the RUN position.

While in RVS mode all modules that are powered by the Run/Crank shall be active and understand that RVS is active. All on-board diagnostics (OBD) II functions shall also be active.

The current state of RVS can be viewed through the driver information center (DIC) display under the Remote Start the display will read either On or Off.

The HVAC preset RVS settings are as follows:

• Inside air temperature input below 22°C (72°F) the HVAC system will set the blower motor speed to high speed, set the mode door to the defrost position, set the temperature door to the full hot position and set the recirculation door to the outside air position.
• Inside air temperature input above 26°C (79°F) the HVAC system will set the blower motor speed to high speed, set the mode door to the panel position, set the temperature door to the full cold position, request air conditioning (A/C) compressor operation and set the recirculation door to the recirculate position.
• Inside air temperature input between 22°C (72°F) and 26°C (79°F) the HVAC system will set the blower motor speed to a medium speed, set the mode door to the panel position, set the temperature door to the full cold position, request A/C compressor operation and set the recirculation door to the outside air position.

Once the ignition switch is placed to the RUN position the HVAC system reverts back to its last known setting.
