Contains a number that  you will need if you 
purchase a replacement key.
Low Keyless Access Re mote Signal Strength
The vehicle transmits radio waves to locate  the keyless access remote when locking/
unlocking the doors, opening the trunk, or to start 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 transmitted by nearby equipment.
• You are carrying the keyless access re mote together with telecommunications 
equipment, laptop computers, ce ll phones, or wireless devices.
• A metallic object is touching or  covering the keyless access remote.
■Key Number Tag1Key Number Tag
Keep the key number tag separate from the key in a 
safe place outside  of your vehicle.
If you wish to purchase an additional key, contact a 
dealer.
If you lose your key and  you cannot start the engine, 
contact a dealer.
1 Low 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 receivi ng strong radio wave s. Avoid placing 
it near electrical  appliances such as  televisions and 
personal computers.
