Turn remote start off for service (valet mode)

Put the system in valet mode before the vehicle goes in for service, or when it's parked indoors or anywhere it shouldn't start.

  • 1. Ignition to ACCTurn the ignition to the first position. On push-button cars, press the start button once without your foot on the brake.
  • 2. Open the RADIO screenPress the Home button on the steering wheel and use the touch pad to pick RADIO on the instrument cluster.
  • 3. Open the menuPress and hold mute (press in on the volume wheel) until Rem Starter On/Off shows, then let go.
  • 4. Change and savePress and release mute to switch between On and Off. Leave the controls alone for about 7 seconds until Settings Saved shows, then turn the ignition off.

No volume and mute buttons on the steering wheel? Mid City's guides above show the turn signal stalk method.

If the module loses power (unplugged, or the battery is disconnected or goes flat), the settings go back to the factory defaults and have to be set again.

The EIS modification on this kit

Kits marked ⒺⒾⓈ need Mid City's EIS modification: the EIS (the ignition module in the dash) comes out and gets a soldered change so the remote starter can start the car.

When we install it, we send the EIS out to a local specialist (same day to 1 day) or to Mid City (about a week). The EIS modification is included in the installed price on our vehicle pages.

Installers: Mid City's EIS steps for this kit are under Manuals and guides.
