RX350_U_OM48E90U Your Lexus is equipped with several sophis ticated computers that will record certain
data, such as:
• Engine speed
• Accelerator status
•Brake status
• Vehicle speed
•Shift position
The recorded data varies according to the ve hicle grade level and op tions with which it is
equipped. Furthermore, these computers do not record conversations, sounds or pic-
tures. ●
Data usage
Lexus may use the data recorded in these computers to diagnose malfunctions, con-
duct research and development, and improve quality.
Lexus will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle
is leased
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a law suit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner●

RX350_U_OM48E90U 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 an d disposed of by a qualified service shop or
by your Lexus dealer before you scrap your vehicle.
Special handling may apply, See www.dts c.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.Scrapping of your Lexus

General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have im paired your ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers or
pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full atte ntion to driving. Anything that distracts the
driver, such as adjusting controls, talking on a cellular phone or reading can result in a
collision with resulting death or serious in jury to you, your occupants or others.■
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
or panoramic moon roof, or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

RX350_U_OM48E90U ■
If the SRS airbags deploy (inflate) ●
Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases. ●
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 th e 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. ●
For Lexus Enform Safety Connect subscribers, if the SRS airb ags 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 vehicl e’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 communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. (  P. 5 4 7 )■
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 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 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 possib le that only the seat belt pretensioners will
activate. ●
The SRS front airbags for the front passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the se at is unoccupied. (  P. 4 9 )●
The SRS seat cushion airbag on the front passenger seat will not operate if the occu-
pant is not wearing a seat belt. ■
SRS airbag deployment conditions (S RS side and curtain shield airbags)●
The SRS side and curtain shield airbags wi ll deploy in the even t of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1 500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 -18 mph [20 -30 km/h]). ●
The SRS curtain shield airbags will deploy in the event of vehicle rollover. ●
The SRS side and curtain shield airbags will deploy in the event of a severe frontal colli-
sion.

TWR (Trailer Weight Rating)
The maximum allowable gross trailer
weight. The gross trailer weight is
the sum of the trailer weight and the
weight of the cargo in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package (if avail-
able), hitch and hitch systems (if
required). Additional optional equipment, passengers and cargo in the vehicle will reduce the
trailer weight rating so as not to exceed GCWR, GVWR and GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended to use a
trailer with 2 or more axles.■
Unbraked TWR (Unbraked Trailer Weight Rating)
The trailer weight rating for towing a
trailer without a trailer service brake
system.

The gross trailer weight must never exceed 3500 lb. (1588 kg). ●
The gross combination weight must never exceed the following:
2WD models: 9165 lb. (4157 kg)
AWD models: 9360 lb. (4246 kg) ●
The gross vehicle weight must never
exceed the GVWR indicated on the
Certification Label. ●
The gross axle weight on each axle
must never exceed the GAWR indi-
cated on the Certification Label. ●
If the gross trailer weight is over the unbraked TWR, trailer service brakes are
required. ●
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with
sufficient capacity is required.
Confirm that the gross trailer weight, gross combination weight, gross vehicle
weight, gross axle weight and tongue weight are all within the limits.■

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transaxle, transfer (AWD models), rear differential (AWD models) or wheel
bearing), Lexus recommends that you do not tow a trailer until the vehicle has been
driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will requir e more frequent maintenance due to the addi-
tional load. (See “Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Scheduled Maintenance”.) ●
Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing. ■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal i mmediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. (if enabled, Trailer Sway Cont rol can also help to stabilize the vehicle and
trailer.) ●
After the trailer sw aying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.

254 4-3. Operating the lights and wipers
RX350_U_OM48E90U When the windshield wipers are not being used, they retract to below the hood.
To enable the windshield wipers to be lifted when parking in cold conditions or
when replacing a windshield wiper insert, change the rest position of the wind-
shield wipers to the service position using the wiper lever. ■
Raising the wipers to the service position
Within approximately 40 seconds of
turning the engine switch off, move
the wiper lever to the
(U.S.A.) or (Canada) posi-
tion and hold it for approximately 2
seconds or more. The wipers will move to the service
position.

●
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid ●
Have a service technician inspect the condition of the battery. ●
Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires. Ensure that all tires are of the specified size and the same brand, and that chains
match the size of the tires.
Perform the following according to the driving conditions: ●
Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing. ●
To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield. ●
Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes. ●
Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.Winter driving tips Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
