●The keyless entry system operation may vary due to local conditions.

when the ignition is switched off. The system does not operate if the ignition
is switched to any position other than off.
● If the key does not operate when pressing a button or the operational range
becomes too small, the battery may be dead. To install a new battery, refer
to Key Battery Replacement ( →P. 436).
● Additional keys can be obtained at your Toyota dealer. Up to 6 keys can be
used with the keyless functions per vehicle. Bring all keys to your Toyota
dealer when additional keys are required.

bination meter. Replacing the battery

Interior Features
●Battery saver
If any door is left open with the overhead light switch in the DOOR posi\
tion,
or the trunk lid is left open, the overhead light or trunk light turns off after
about 30 minutes to prevent battery depletion.
● To prevent battery depletion, if the interior lights remain turned on (the inte-
rior light switch is in the ON position or an interior light is turned on by press-
ing the lens of the interior light), they turn off automatically under the
following conditions:
• No operations are done for about 30 minutes after the ignition is switched
off.
• When the LOCK button on the key is pressed after the ignition is switched off (interior lights turn off a few seconds).
In addition, if the following operations are performed after turning the inte-
rior lights off, they will turn on again.
• The ignition is switched to a position other than OFF.
• A door is opened.
• A door is unlocked.
● The operation of the illuminated entry system can be changed.
