■Accessing voicemail and sending number tones to an automated
phone system
You can access a voicemail system and respond to a number request
from an automated phone system. When you receive the request for a
number while in a call, press the button after saying the numbers
one at a time, say “Dial”.
If you do not say any commands within 5 seconds after pressing the button,
or if you press the button twice, the system cannot receive the number tones
you are trying to send. Press the button to try again.
■ How to retrieve your phone number
Press the button. When the system responds with “Lexus
Link ready”, say “My number”.
The system responds with “Your number is [#]”.
If the response is “Personal calling unavailable”, this means your personal
calling feature is not yet active, this may take a few days from vehicle
delivery. It could also mean that the personal calling service is not avail-
able in your area. Press the button to check with an Advisor. Now
that you have your number, take a moment to practice by making your
first call to your home phone. Remember, the system recognizes numbers
better when you say them quickly.

■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.

●Tips for entering a phone number using the “Dial” and “Store” commands
• You do not need to say “Dial”, “Store” or “Verify” after the phone number.
• If the phone number entered is not 7, 10, or 11 digits, use the “Dial” or “Store”command.
• Do not pause between the digits.
• Speech recognition does not recognize the words “Hundred” or “Thousand”. Instead, say each digit.
• Speech recognition often works better when the digits are combined
smoothly into a single phrase.
• If the system does not recognize your command properly, use the “Digit dial” command to enter one digit at a time.
●If problems continue
• Say each one of the syllables in the word clearly.
• Be sure to articulate each sound in the word.
• If the system is confusing 2 commands that are similar, be sure to pronounce
the distinction.
• Avoid clipping short words and syllables.
• Try speaking louder to prevent background noise from drowning out your voice.
●Audible voice prompts
Some of the voice guidance instructions can be changed to Spanish. Press the
button and ask a Lexus Link Advisor.

Maintenance requirements
■Repair and replacement
It is recommended that genuine Lexus parts be used for repair to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair
shop other than a Lexus dealer performs repairs, confirm the warranty coverage.
To ensure safe and economical driving, day-to-day care and regular main-
tenance is essential. It is the owner’s responsibility to perform regular
checks. Lexus recommends the following maintenance.
■General maintenance
Should be performed on a daily ba sis. This can be done by yourself
or by a Lexus dealer.
■ Scheduled maintenance
Should be performed at specified intervals according to the mainte-
nance schedule.
For details about maintenance items and schedules, refer to the “War-
ranty and Services Guide/Owner’s Manual Supplement/Scheduled
Maintenance”.
■Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Lexus service and repair manuals is recommended.
For details about warranty coverage, see the separate “Owner’s Guide”,
“Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Warranty Booklet”.

4-2. Maintenance
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the
latest service information. They are well informed about the operations of all
systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been
performed is under warranty coverage. If any problem should arise while your
vehicle is under warranty, your Lexus dealer will promptly take care of it.
CAUTION
■Hazardous materials
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by compo-
nent wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and wash
any affected area immediately.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after han-

Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which include
OBD (On Board Diagnostics) checks. The OBD system monitors the oper-
ation of the emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere in
the emission control system. Your vehicle may not pass the I/M test
and may need to be repaired. Cont act your Lexus dealer to service
the vehicle.
■ Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are set du ring ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator la mp goes off after several driv-
ing trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Lexus dealer to prepare the vehicle for re-testing.
