■Speech recognition information
The Lexus Link speech recognition systems use speech technology that is designed
to understand a wide range of speakers of American English. However, the technol-
ogy may not work as well if a regional or ethnic accent is encountered. If the speech
recognition system does not work properly, refer to the following.
●The system does not recognize your command properly if noise is present. Per-
form the following to improve voice command recognition.
• Turn down or off the air conditioning system.
• Slow down to reduce wind noise.
• Close the windows and the moon roof to block outside noise.
• Have all occupants be quiet so that the system does not recognize their con-
versation as a command.
●When to speak
Say a command within 5 seconds after the system prompts you to speak.
●How to speak
• Speak forcefully and clearly.
• Speak calmly and naturally.
• The driver should speak while facing forward, and the passenger should speak facing the inside rear view mirror.
• Avoid speaking with a rising intonation. Use a flat or falling intonation.
●Tips for one-word commands
• The system recognizes only one word at a time for personal calling. (There are some exceptions, such as “Advanced services” and “My number”.)
• When inputting the security codes or voice-activated keypad number, you
must say them one digit at a time. When inputting a phone number, the
speech recognition system can recognize 7, 10, and 11-digit numbers as well
as the number 911.

CAUTION
■Replacing light bulbs
●Turn off the headlights. Do not attempt to replace the bulb immediately after turn-
ing off the headlights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. Hold the bulb by
the plastic or metal portion.
If the bulb is scratched or dropped it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failing to do so may
result in heat damage, fire, or water entering the headlight unit. This may damage
the headlights or cause condensation to build up on the lens.
●Do not attempt to repair or disassemble light bulbs, connectors, electric circuits
or component parts.
Doing so may result in serious injury due to electric shock.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.
