Controls
Low Keyless Access Remote Signal StrengthThe vehicle transmits radio waves to locate the keyless access remote when locking/
unlocking the doors and tailgate, or to start the engine.
In the following cases, locking/unlocking the doors and tailgate, or starting the
engine may be inhibited or operation may be unstable:
• Strong radio waves are being transmitted by nearby equipment.
• You are carrying the keyless access remote together with telecommunications
equipment, laptop computers, cell phones, or wireless devices.
• A metallic object is touching or covering the keyless access remote.
1Low Keyless Access Remote Signal Strength
Communication between the keyless access remote
and the vehicle consumes the keyless access remote’s
battery.
The keyless access remote battery lasts about two
years. This changes by how often you use the remote.
The battery is consumed whenever the keyless access
remote is receiving strong radio waves. Avoid placing
it near electrica l appliances such as televisions and
personal computers.
