■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.

Maintenance and care
■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the window in strokes running parallel to the
heater wires.
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlappin g circles. Do not apply water. The excel-
lent results are obtained by keep ing the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Be careful not to splash or spill liquid on the floor.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(  P. 7 7 )
Electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or serious injury.

4-1. Maintenance and care
NOTICE
■Cleaning detergents
Do not use the following types of detergent, as they may discolor the vehicle inte-
rior or cause streaks or damage to painted surfaces.
●Non-seat portions: Organic substances su ch as benzene or gasoline, alkaline or
acidic solutions, dye, or bleach.
●Seats: Acidic solutions, such as thinner, benzene, or alcohol.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces.
●Remove any dust or dirt on leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended pe riods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or that contain wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio syst em may be damaged if water comes into
contact with electrical components under the floor of the vehicle, and may also
cause the body to rust.
■Cleaning the inside of the rear window
Be careful not to scratch or damage the heater wires or antenna.

■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 365)
●If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
■If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.

5-2. Steps to take in an emergency
The tire pressure warning system may become inoperative in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used. (Even if you use genuine Lexus wheels,
the tire pressure warning system may not work properly with some types of
tires.)
●If tire chains are used.
●If the spare tire is in a location subj ect to poor radio wave signal reception.
● If a large metallic object which can interfere with signal reception is put in the
luggage compartment.
■If the tire pressure warning light comes on after blinking for 1 minute frequently
If the tire pressure warning light comes on after blinking for 1 minute frequently
when the engine switch is turned to the “ON” position, have it checked by your
Lexus dealer.
■After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. ( P. 3 2 6 )
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat ti re. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.

5-2. Steps to take in an emergency
■Starting the engine when the battery is discharged
The vehicle cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic, etc.
■When the battery is removed or discharged
The power windows and moon roof must be initialized.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery.
●Make sure the jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any pa rt other than the intended terminal.
●Do not allow the jumper cables to come into contact with the “+” and “-” termi-
nals.
●Do not allow open flame or use matches, cigarette lighters or smoke near the
battery.
Once your vehicle’s engine has started, remove the jumper
cables in the exact reverse ord er in which they were con-
nected.
Once the engine starts, have the ve hicle checked at your Lexus dealer
as soon as possible.STEP5
