Rear sunshade∗
■The rear sunshade can be used when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Reverse operation feature
To ensure adequate rear visibility, the sunshade automatically lowers when the shift
lever is shifted to “R”.
However, the rear sunshade is raised again if any of the following occurs:
●Shift the shift lever into “P”.
●The switch is pressed again.
●The shift lever is shifted out of “R”, and the vehicle reaches a speed of 9 mph (15
km/h).
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.
∗: If equipped
The rear sunshade can be raised and lowered by pressing the switch shown
below.

Safety information for the Lexus Link System
Important! Read this information before using the Lexus Link System. ■Exposure to radio frequency signals
The Lexus Link System installed in your vehicle is a low power ratio trans-
mitter and receiver. When the “ENGINE START STOP” switch is in the
IGNITION ON mode, it receives and also sends radio frequency (RF)
signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previ-
ously set by both U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comp rehensive and periodic evaluations
of the relevant scientific literature. Over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry
reviewed the available body of resear ch to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies with the FCC guidelines in
addition to those standards.

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 easi ly, 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 3 2 )
■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 consumpt ion, 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.
■Resetting the engine oil main tenance data (U.S.A. only)
Perform the following steps:
Press the “DISP” switch ( →P. 153) to change the multi-information dis-
play to blank.
Turn the “ENGINE START STOP” switch to OFF.
Turn the “ENGINE START STOP” switch to IGNITION ON mode with
the trip meter reset button held down.
Keep pressing the button for longer than 7 seconds after the “ENGINE
START STOP” switch is in IGNITION ON mode.

■How to initialize the tire pressure warning system
Park the vehicle in safe plac e and turn the “ENGINE START
STOP” switch to OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( →P. 570)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly three times and the mes-
sage “PRESSURE INITIAL”
appears on the multi-information
display.
Wait for a few minutes with the IGNITION ON mode, and then
turn the “ENGINE START STOP” switch to OFF.

Towing eyelet
■Emergency towing procedureRelease the parking brake.
Put the shift lever in “N”.
The “ENGINE START STOP” switch must be in the ACCESSORY mode
(engine off) or the IGNITION ON mode (engine on).
CAUTION
■While towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelet and the cable or chain.
●If the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
NOTICE
■To prevent causing serious damage to the automatic transmission
Never tow this vehicle from the front with the rear wheels (2WD models) or four
wheels (4WD models) on the ground.
This may cause serious damage to the automatic transmission.
