Perchlorate Material WARNING ■
General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired 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 driv e defensively. Anticipate mistakes that other drivers or
pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to drivin g. 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 rega rding children’s safety
Never leave children unattended in the vehicl e, and never allow child ren 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 play ing with the windows, the moon
roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem-
peratures inside the vehicle can be fatal to children.

For safety and security ■
If the SRS airbags deploy (inflate) ●
Slight abrasions, burns, brui sing 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 the front, side and rear pillars and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.●
The windshield may crack. ●
For Lexus Enform 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 occupa nts 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. 452)WARNING ■

consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differen tial 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 “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.) ●
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 ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the st eering or brakes, your vehicle and trailer
should stabilize. ●
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 ov erloaded 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.
