The HHR by Chevrolet has the convenient option of starting its engine using the keychain remote. This will allow the air conditioner or heater to bring the car to a comfortable temperature before entering. This can be especially useful in avoiding burns from hot surfaces in desert climates. This option is built in to the on-board computer but may require the purchase of a specialized four-button keychain remote from your dealer.
Start the engine and leave the car in park.
Hold the info and select buttons on the steering wheel for 3 seconds and release. The dash readout will now enter the settings menu.
Press the info button repeatedly until it reads "Remote Start: Off." Press the select button until it reads "Remote Start: On." Turn off the engine.
Press the lock button on the remote.
Hold the start button on the remote for 3 seconds (commonly a loop symbol) until the engine starts.
Press the unlock button, insert the key into the ignition and turn it to the "on" position.
