Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.

Before driving
ES350_UThe main SRS airbag system components are shown above. The SRS
airbag system is controlled by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■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, and parts of the front pillar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (
oP. 3 4 6 )
■SRS airbag deployment conditions (front airbags)
●The front SRS airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to a 12 - 18 mph [20 - 30 km/h]
frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
● Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
●Tire inflation pressure falls in winter as the outside temperature
falls. Add 2.9 to 4.3 psi (20 to 30 kPa, 0.2 to 0.3 kgf/cm2 or bar)
to the standard tire inflation pressure.

■Before towing
●Ensure that your vehicle’s tires are properly inflated. (oP. 396)
●Trailer tires should be inflated according to the trailer manufacturer's recom-
mendation.
●All trailer lights work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide/Owner's Manual Sup-
plement/ Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
1000 lb. (450 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue load capacities.
●Never load more weight in the back than in the front of the trailer. About 60% of
the load should be in the front half of the trailer, and the remaining 40% in the
r e a r.

■When the battery is disconnected
All preset stations are erased.
■Reception sensitivity
●It is difficult to maintain perfect radio reception at all times due to the continually
changing position of the antenna, differences in signal strength and surrounding
objects, such as trains and transmitters.
●The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.
