NOTICE
■How to use the cameras
●Observe the following precautions. Failure to do so may prevent the Multi-terrain
Monitor from operating properly.
• Do not strike the camera area, or allow any objects to bump into it
If the camera or surrounding area has re ceived a strong impact, the camera posi-
tion, installation angle, etc., may deviate. If the camera is accidentally subjected to
an impact, have the vehicle inspected at your Lexus dealer.
• Do not remove, disassemble or modify the camera or surrounding parts
Doing so may result in the camera malfunct ioning. This also may result in a loss of
waterproof performance.
• If the camera lens is dirty, follow the above procedures to clean it
If the camera lens is damaged it cannot transmit a clear image.
Do not allow organic solvent, car wax, oil film remover, glass coating, etc. to con-
tact the camera cover
Doing so will negatively affect the camera co ver (resin). If this happens, wipe it off
immediately.
• When the outside temperature is cold, do not cause any sudden changes in tem-
perature, such as by applying hot water
●When washing the vehicle, do not apply water with a high-pressure washer to the
camera or surrounding area. Doing so ma y cause the camera to receive a strong
impact, and the camera may not operate properly

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically energize d. 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 driving
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 com-
partment.
●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 corro-
sive sulfuric acid.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the
electric cooling fans may auto matically start to run if the air conditioning is on and/or
the coolant temperature is high. ( P. 457)
■When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■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 f ilter removed may cause excessive engine wear due to dirt
in the air.

tery” is shown
Power was turned off due to the automatic power off function. Next time when starting
the engine, increase the engine speed slightly and maintain that level for approximately 5
minutes to recharge the battery.
■If “ENGINE OIL PRES SURE LOW”/“Oil Pressure Low Stop in a Safe Place See
Owner’s Manual” is shown

Immediately stop the vehicle in a safe place and contact your Lexus dealer. Continuing to
drive the vehicle may be dangerous.
■If “HIGH TRANSMISSION FLUID TEMPERAT URE”/“High Transmission Fluid Temp

Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.
Oil viscosity (0W-20 is explained here as an example): • The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value be fore the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme lo ad conditions.
How to read oil container label:
The International Lubricant Specifi-
cation Advisory Co mmittee (ILSAC)
Certification Mark is added to some
oil containers to help you select the
oil you should use.
