In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicl e’s location and attempts to speak
with the vehicle occupants to asse ss the level of emergency. If the
occupants are unable to communicate, the agent automatically treats
the call as an emergency, contacts the nearest emergency services
provider to describe the situation, and requests that assistance be sent
to the location.

6664-3. Do-it-yourself maintenance
CAUTIONThe engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions: ■
When working on the engine compartment ●
Keep hands, clothing and tools away from the moving fans and engine drive belt.●
Be careful not to touch the engine, radiator , exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.●
Do not leave anything that may burn easi ly, such as paper and rags, in the engine
compartment.●
Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.●
Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.■
When working near the electric cooling fans or radiator grille
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (  P. 6 7 8 )■
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes.
NOTICE■
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air.

6924-3. Do-it-yourself maintenance
NOTICE■
Repairing or replacing tires, wheels, ti re pressure warning valves, transmitters
and tire valve caps ●
When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitter, contact your Lexus dealer as the tire pressure warning valves and
transmitters may be damage d if not handled correctly.●
When replacing tire valve caps, do not us e tire valve caps other than those speci-
fied. The cap may become stuck.■
To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid seal ants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact your Lexus
dealer or other qualified service shop as so on as possible. Make sure to replace the
tire pressure warning valve and transmitter when replacing the tire. (  P. 685)■
Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driv ing on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.■
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

6964-3. Do-it-yourself maintenance
CAUTION■
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and result in an accident causing death or serious injury: ●
Excessive wear●
Uneven wear●
Poor handling●
Possibility of blowouts resulting from overheated tires●
Poor sealing of the tire bead●
Wheel deformation and/or tire separation●
A greater possibility of tire damage from road hazards
NOTICE■
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture co uld get into the valve and cause air leak-
age, which could result in an accident. If the caps are lost, replace them as soon as
possible.
