CAUTION
SRS airbag precautions
Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
If the areas where the SRS airbags are stored, such as the steering wheel
pad, door of the glove box and front and rear pillar garnishes are damaged
or cracked, have them replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifica-
tions without consulting any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional. The SRS airbags may malfunc-
tion or deploy (inflate) accidentally, causing death or serious injury.
Installation, removal, disassembly and repair of the SRS airbags
Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, glove box, seats or seat upholstery, front,
side and rear pillars or roof side rails
Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows or
winches
Modifications to the vehicle’s suspension system
Installation of electronic devices such as mobile two-way radios (RF-
transmitter) and CD players
Modifications to your vehicle for a person with a physical disability

If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, the glove box, parts of the front and rear pillars, and roof
side rails may be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
SRS airbag deployment conditions (SRS front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 20
- 30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not
move or deform).
However, this threshold velocity will be considerably higher in the follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
SRS airbag deployment conditions (SRS side and curtain shield airbags)
The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 1500 kg [3300 lb.] vehi-
cle colliding with the vehicle cabin from a direction perpendicular to the
vehicle orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
The SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.

The surface of the seats with the side
airbag is scratched, cracked, or other-
wise damaged.
The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain shield airbags
inside is scratched, cracked, or other-
wise damaged.

the accelerator and gently apply the brakes. A greater amount of
electrical energy can be retained when slowing down.
Air conditioning
Use the air conditioning only when necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeat-
edly warm up, which can lead to poor fuel consumption.

When using the microphone
It is unnecessary to speak directly into the microphone when giving a com-
mand.
Wait for the confirmation beep before speaking a command.
Speech commands may not be recognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while speech commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
In the following conditions, the system may not recognize the command
properly and using speech commands may not be possible:
• The command is incorrect or unclear. Note that certain words, accents or
speech patterns may be difficult for the system to recognize.
• There is excessive background noise, such as wind noise.
When searching for a track
A USB memory or iPod must be connected to enable track searching and
playback. (P. 579, 590)
When a USB memory or iPod is connected, recognition data is created so
tracks can be searched using speech commands.
Recognition data is updated under the following conditions:
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. (P. 456)
While the recognition data is being created or being updated, a track search
cannot be performed using a speech command.
When “Play music” is dimmed in the “Shortcuts” screen, it is not possible
to search for a track using a speech command. In this situation, reduce the
amount of music data in the USB memory or iPod and update the recogni-
tion data to enable searching by speech command.
