Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Select Park and press the brake pedal firmly.
- 02
Touch the Intelligent Key directly against the push-button ignition switch and listen for the chime.
- 03
Within 10 seconds, push the ignition switch while continuing to hold the brake.
- 04
Replace the Intelligent Key battery promptly after the engine starts.
Important limits
- The procedure is for a discharged Intelligent Key battery, not for a discharged vehicle battery.
- Use the key assigned to the vehicle and keep other keys, phones and metal objects away from the switch.
- Pushing the ignition without the brake may only change ignition mode.
Quick checks.
- ✓If no chime sounds, change the key's contact angle and place it directly against the switch center.
- ✓If the 10-second window expires, remove the key and repeat from the contact step.
- ✓If the engine still does not start, confirm Park and brake-pedal input; a no-crank condition may be the vehicle's 12-volt battery rather than the key battery.
