Low Remote Signal Strength
The vehicle transmits radio waves to locate  the remote when locking/unlocking the 
doors*, tailgate*, and fuel fill door*, opening the power sliding door* and the power 
tailgate*, or to start the engine.

• You are carrying the remote together  with telecommunications equipment, 
laptop computers, cell phone s, or wireless devices.
• A metallic object is touchi ng or covering the remote.
1Low Remote Signal Strength
Communication between the  remote and the vehicle 
consumes the remote’s battery.
Battery life is  about two years,  but this varies 
depending on re gularity of use.
The battery is consumed whenever the remote is 
receiving strong radio waves.  Avoid placing it near 
electrical appliances such  as televisions and personal 
computers.
