■The rear sunshade can be used when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Reverse operation feature
This function will become operational when the rear sunshade is in the raised posi-
tion and the vehicle has been driven at 9 mph (15 km/h) or more or with the shift
lever in P.
To ensure adequate rear visibility, the sunshade automatically lowers when the shift
lever is shifted to “R” and the function is in an operational condition.
However, the rear sunshade is raised again if any of the following occurs:
●Shift the shift lever into “P”.
●The shift lever is shifted out of “R”, and the vehicle reaches a speed of 9 mph
(15 km/h).
●The switch is pressed again.*
*
: Occasionally, the reverse function may not be carried out after the switch has
been pressed. Repeat the above operation to operate the function.
If the engine is turned off when the rear sunshade has been lowered due to the
reverse operation feature, it will not be raised even when the engine is turned on
again and the vehicle reaches a speed of 9 mph (15 km/h). To raise the sunshade
again, press the switch.
■After the “ENGINE START STOP” switch is turned to OFF
The rear sunshade can be raised and lowered for approximately 1 minute.

■Automatic Collision Notification
In case of either airbag deployment or severe collision, the system is
designed to automatically call the response center. The responding
agent receives the vehicle’s location and attempts to speak with the
vehicle occupants to assess 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 loca-
tion.

CAUTION
The 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 fan 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 easily, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the 12 volt battery.
Fuel and 12 volt battery fumes are flammable.
●Be extremely cautious when working on the 12 volt battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cooling fan 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 fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (P. 4 5 7 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the 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. Also a backfire could cause a fire in the engine compartment.

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds, frequent
acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp.qt./600 miles (1.0 L per 1000
km). If the vehicle consumes more than this amount, contact your Lexus dealer.
