Repair and replacement
It is recommended that genuine Lexus parts
be used for repairs to ensure performance
of each system. If non-Lexus parts are used
in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm
the warranty coverage.
■
Allow inspection and repairs to be per-
formed by a Lexus dealer
●
Lexus technicians are well-trained spe-
cialists and are kept up to date with the
latest service information. They are well
informed about the operation of all sys-
tems on your vehicle.
●
Keep a copy of the repair order. It proves
that the maintenance that has been per-
formed is under warranty coverage. If any
problem should arise while your vehicle is
under warranty, your Lexus dealer will
promptly take care of it.
General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.
For details about maintenance items and
schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

●
Oils, fuels and fluids contained in vehi-
cles as well as waste produced by
component wear contain or emit
chemicals known to the State of Cali-
fornia to cause cancer and birth
defects or other reproductive harm.
Avoid exposure and wash any affected
area immediately.

The OBD system determines that a
problem exists somewhere in the emis-
sion 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.
When the battery is disconnected
or discharged
Readiness codes that are set during ordi-
nary 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
indicating a temporary malfunction and
your vehicle may not pass the I/M test.
The error code in the OBD system will
not be cleared unless the vehicle is
driven 40 or more times.
Contact your Lexus dealer to prepare
the vehicle for re-testing.
Emission inspection and
maintenance (I/M) pro-
grams
Some states have vehicle emission
inspection programs which include
OBD (On Board Diagnostics)
checks. The OBD system monitors
the operation of the emission con-
trol system.
If the malfunction indicator lamp
comes on
Your vehicle may not pass the
I/M test in the following situa-
tions:
When the malfunction indicator
lamp still remains on after sev-

WARNING
The engine compartment contains many
mechanisms and fluids that may move
suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
■
When working on the engine com-
partment
●
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 and rags, in the
engine compartment.
●
Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.

When working near the electric cool-
ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION
ON mode, the electric cooling fan may
automatically start to run if the air condi-
tioning is on and/or the coolant tempera-
ture is high. (

Coolant selection
Only use “Toyota Super Long Life Coolant”
or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -31°F
[-35°C])
Canada:
“Toyota Super Long Life Coolant” is a mix-
ture of 55% coolant and 45% deionized
water. (Minimum temperature: -44°F
[-42°C])
For more details about coolant, contact
your Lexus dealer.
■
If the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses, engine
coolant reservoir caps, drain cock and
water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator, condenser, inter-
cooler radiator and intercooler sub
radiator and clear away any foreign
objects. If either of the above parts is
extremely dirty or you are not sure of
their condition, have your vehicle
inspected by your Lexus dealer.

WARNING
■
When the engine is hot
Do not remove the engine coolant reser-
voir cap, the intercooler coolant reser-
voir cap and the coolant inlet cap.
(
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
NOTICE
■
When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
■
If you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.

Brake fluid can absorb moisture from
the air
Excess moisture in the brake fluid can cause
a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
If any washer does not work or the
warning message appears on the
multi-information display, the washer
tank may be empty. Add washer fluid.
WARNING
■
When the engine is hot
Do not touch the radiator, condenser,
intercooler radiator or intercooler sub
radiator as they may be hot and cause
serious injuries, such as burns.
Checking and adding the brake
fluid
WARNING
■
When filling the reservoir
Take care as brake fluid can harm your
hands and eyes and damage painted sur-
faces.
If fluid gets on your hands or in your eyes,
flush the affected area with clean water
immediately.
If you still experience discomfort, see a
doctor.
NOTICE
■
If the fluid level is low or high
It is normal for the brake fluid level to go
down slightly as the brake pads wear out
or when the fluid level in the accumulator
is high.
If the reservoir needs frequent refilling,
there may be a serious problem.
Adding the washer fluid
WARNING
■
When adding washer fluid
Do not add washer fluid when the engine
is hot or running as washer fluid contains
alcohol and may catch fire if spilled on
the engine, etc.
