CAUTION
■Caution while driving
Do not adjust the display.
Be sure to adjust the display on ly when the vehicle is stopped.
■When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the neigh-
borhood. Do not violate any local traffic rules while performing circling calibration.
NOTICE
■To avoid the compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror. 
Doing this may cause a malfunction of the compass sensor.
■To ensure normal operation of the compass
●Do not perform circling calibration of the compass in a place where the earth's
magnetic field is subject to interference by artificial magnetic fields.
●During calibration, do not operate electr ic systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

■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 intonati on. 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.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows. Before entering an automatic car wash, check that the fuel filler door is
closed.
■Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard brushes
or abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same
mild detergent and wax as used on the paint.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
● Working from top to bottom, liber ally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
Wash the vehicle body using a sponge or soft cloth, such as a chamois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● If water no longer beads on clea n paint, apply wax when the vehi-
cle body is cool.
