 Intercooler Remove the engine compartment cover
and add coolant. 6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan oper-
ates and to check for coolant leaks
from the radiator or hoses. The fan operates when the air conditioning
system is turned on immediately after a
cold start. Confirm that the fan is operating
by checking the fan sound and air flow. If it
is difficult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fan may not oper ate in freezing tem-
peratures.)
7 If the fan is not operating:
Stop the engine immediately and
contact your Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the
nearest Lexus dealer. ■

When inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns. ●
If steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot. ●
Keep hands and clothing (especially a
tie, a scarf or a muffler) away from the
fan and belts.
Failure to do so may cause the hands
or clothing to be caught, resulting in
serious injury. ●
Do not loosen the coolant inlet cap,
the engine coolant reservoir cap or the
intercooler coolant reservoir cap while
the engine and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
■
When adding engine coolant
Add coolant slowly after the engine has
cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can
cause damage to the engine.
■
To prevent damage to the cooling sys-
tem
Observe the following precautions:
●
Avoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).

When trouble arises 1 Stop the engine. Set the parking
brake and shift the shift position to
P.
2 Remove the mud, snow or sand
from around the rear wheels.
3 Place wood, stones or some other
material under the rear wheels to
help provide traction.
4 Restart the engine.
5 Shift the shift position to D or R and
release the parking brake. Then,
while exercising caution, depress
the accelerator pedal. ■
When it is difficult to free the vehicle
Press the switch to turn off TRAC.NOTICE●
Do not use any coolant additive.
If the vehicle becomes stuck Carry out the following proce-
dures if the tires spin or the vehicle

Oil capacity (Drain and refill [Ref-

: The engine oil capacity is a reference
quantity to be used when changing the
engine oil. Warm up and turn off the
engine, wait more than 5 minutes, and
check the oil level on the dipstick.■
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 starting
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.
Recommended viscosity (SAE):
Outside temperature
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 before the W allow for easier
starting of the engine in cold
weather.
• The 20 in 0W-20 indicates the vis-
cosity 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 load con-
ditions.

Vehicle specifications ■
Gasoline quality
In very few cases, driveability problems may
be caused by the brand of gasoline you are
using. If driveability problems persist, try
changing the brand of gasoline. If this does
not correct the problem, consult your Lexus
dealer. ■
Recommendation of the use of gasoline
containing detergent additives●
Lexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.●
All gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additive s concentration pro-
gram.
●
Lexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gaso-
line and a list of marketers, please go to
the official websit e www.toptiergas.com.
■
Recommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments.
Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions. ■
Non-recommendation of the use of
blended gasoline ●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30 (30% ethanol [ ]), E50 (50%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
●
If you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
91. ●
Lexus does not recommend the use of
gasoline containing methanol. ■
Non-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected.
The malfunction indicator lamp on the
instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
■
If your engine knocks
●
Consult your Lexus dealer.
●
You may occasionally notice light knock-
ing for a short time wh ile accelerating or Fuel information You must only use unleaded gaso-
line.
Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number 96) or
higher required for optimum
engine performance and fuel econ-
omy.
If the octane rating is less than 91,
damage to the engine may occur
and may void the vehicle warranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A. A

no need for concern.
NOTICE■
Notice on fuel quality●
Do not use improper fuels. If improper
fuels are used, the engine will be dam-
aged.●
Do not use leaded gasoline.
Leaded gasoline can cause damage to
your vehicle’s three-way catalytic con-
verters causing the emission control
system to malfunction.●
Do not use gasohol other than the type
previously stated.
Other gasohol may cause fuel system
damage or vehicle performance prob-
lems.●
Using unleaded gasoline with an
octane number or rating lower than
the level previously stated may cause
persistent he avy knocking.
At worst, this may lead to engine dam-
age and will void the vehicle warranty.■
When refueling with gasohol
Take care not to spill gasohol. It can dam-
age your vehicle’s paint.
■
Fuel-related poor driveability
If poor driveability is encountered after
using a different type of fuel (poor hot
starting, vaporization, engine knocking,
etc.), discontinue the use of that type of
fuel.
