CAUTION
SRS airbag precautions
Do not strike or apply significant levels of force to the area of the SRS airbag
components.
Doing so can cause the SRS airbags to malfunction.
Do not touch any of the component parts immediately after the SRS airbags
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
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 modifications
without consulting any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional. The SRS airbags may malfunction 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, instru-
ment panel, dashboard, 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 occu-
pant compartment
Installation of snow plows, winches, etc. to the front grille (bull bars or kan-
garoo bar etc.)
Modifications to the vehicle’s suspension system
Installation of electronic devices such as mobile two-way radios, RF-trans-
mitters 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 (inflat-
ing) 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 front seats, 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 following
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 preten-
sioners 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.] vehicle collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orienta-
tion 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 air-
bag is scratched, cracked, or otherwise
damaged.
The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise damaged.

IS300h_EE(OM53B95E)
Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated
air mode. Doing so will help to reduce the burden on the air condition-
ing system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
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 economy.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel economy. Use tires that are appropriate for
the season.
Luggage
Carrying heavy luggage can lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack can also cause poor
fuel economy.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently
driving short distances will cause the engine to repeatedly warm up,
which can lead to excess fuel consumption.
