The battery in the remote normally
lasts about 2 years. To ensure
maximum battery life, do not store
the remote close to electrical devices
such as computers or TVs. When the
multi-information display shows
''CHANGE KEYLESS REMOTE
BATTERY,'' replace the battery as
soon as possible (see page

If the remote battery becomes weak
and the power door lock/unlock
operation is disabled, you should
insert the remote into the keyless
access remote slot to set the power
mode and start the engine. After
inserting the remote to the slot,
operate the engine start/stop button
as previously described (see pages
178 and 182

Inserting the remote does not charge
the remote battery. You should
replace the battery as soon as
possible.
