Low Keyless Access Remote Signal Strength

Co
ntrols

Contains a number that you will need if you 
purchase a replacement key.

Low Keyless Access Remote 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 remote together with telecommunications 

equipment, laptop computers, cell phones, or wireless devices.

• A metallic object is touching or covering the keyless access remote.

■

Key Number Tag

1

Key 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.
Battery life is about two years, but this varies 
depending on regularity of use.
The battery is consumed whenever the keyless access 
remote is receiving strong radio waves. Avoid placing 
it near electrical appliances such as televisions and 
personal computers.

You can lock or unlock doors using the remote 
transmitter only when the power mode is in VEHICLE 
OFF.

The remote transmitter uses low-power signals, so 
the operating range may vary depending on the 
surroundings.

The remote will not lock the vehicle when a door is 
open.

If the distance at which the remote transmitter works 
varies, the battery is probably low.
