Power Door Locks — If Equipped
The power door lock switches are on each front door trim
panel. Use these switches to lock or unlock the doors.
NOTE:
The key fob may not be able to be detected by the vehicle
Keyless Enter-N-Go system if it is located next to a mobile
phone, laptop or other electronic device; these devices may
block the key fob’s wireless signal and prevent the Keyless
Enter-N-Go system from starting the vehicle.Power Door Lock Switches
If you push the power door lock switch while the key fob is
located inside the vehicle, and any front door is open, the
power locks will not operate. This prevents you from acci -
dentally locking your key fob in the vehicle. Removing the
key fob or closing the door will allow the locks to operate. A
chime will sound if the key fob is in the ignition switch and
a door is open, as a reminder to remove the key fob.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children should
be warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or move
the vehicle.
