4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back and retract the antenna before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows. Before entering an automatic car wash, check that the fuel filler door is
closed.
■Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard brushes
or abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same
mild detergent and wax as used on the paint.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
● Working from top to bottom, liber ally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
Wash the vehicle body using a sponge or soft cloth, such as a chamois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● If water no longer beads on clea n paint, apply wax when the vehi-
cle body is cool.

4-2. Maintenance
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained speciali sts and are kept up to date with the
latest service information. They are well informed about the operations of all
systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been
performed is under warranty coverage. If any problem should arise while your
vehicle is under warranty, your Lexus de aler will promptly take care of it.
CAUTION
■Warning in handling of battery, oils, fuels, and fluids
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by compo-
nent wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and wash
any affected area immediately.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after han-
dling. (P. 2 8 8 )
●Used engine oil contains chemicals that have been shown to cause cancer in lab-
oratory animals. Avoid prolonged and repeated contact. Always protect your
skin by washing thorough ly with soap and water.

4-2. Maintenance
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which include
OBD (On Board Diagnostics) checks. The OBD system monitors the oper-
ation of the emission control system.
■ If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere in
the emission control system. Your vehicle may not pass the I/M test
and may need to be repaired. Contact your Lexus dealer to service
the vehicle.
■ Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator la mp goes off after several driv-
ing trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Lexus dealer to prep are the vehicle for re-testing.

4-3. Do-it-yourself maintenance
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.
■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, inverter, 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
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 fan or radiator grille
Be sure the ignition is off. With the ignition in on, the electric cooling fan may auto-
matically start to run if the air conditioning is on and/or if the coolant temperature is
high.
( P. 2 8 3 )
■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.
●Use eye protection to prevent flying or falling material, fluid spray, etc. from get-
ting 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. Also a backfire could cause a fire in the engine compartment.

Maintenance and care
■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
*: If SAE 5W-30 is not available,SAE 10W-30 may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.

4-3. Do-it-yourself maintenance
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your Lexus dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.
●Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.
●Do not bleed or reduce tire inflation pressure after driving. It is normal for the
tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
