Starting the Engine

Place the transmission in the proper gear.

If the vehicle has the keyless access system, the keyless access transmitter must be authenticated in order for the ignition control knob to turn. The transmitter can be authenticated either by putting your foot on the brake pedal or by pushing the ignition control knob in.
