uuLocking and Unlocking the Doors uLow Remote Key Signal Strength
Controls
Low Remote Key Signal Strength
The vehicle transmits radio waves to locate the remote key when locking/unlocking*
the doors and fuel fill door, opening* the trunk, or starting the engine.
In the following cases, locking/unlocking
* the doors, opening* the trunk, or starting
the engine may be inhibited or operation may be unstable:
• Strong radio waves are being tra nsmitted by nearby equipment.
• You are carrying the remote key together with telecommunic ations equipment,
laptop computers, cell phone s, or wireless devices.
• A metallic object is touching or covering the remote key.
1Low Remote Key Signal Strength
Communication between the remote key and the
vehicle consumes the remote key's battery.
Battery life is about two years, but this varies
depending on re gularity of use.
The battery is consumed whenever the remote key is
receiving strong radio waves. Avoid placing it near
electrical appliances such as televisions and personal
computers.
